2858 Increasing Prevalence of CVD and Its Risk Factors in India: A Review

Authors: Deepa Shokeen, Bani Tamber Aeri

Abstract:

Non-communicable diseases in general and cardiovascular diseases (CVD) in particular are a big cause of concern worldwide especially in fast growing economy like India. CVD is one of the leading causes of deaths in India. Risk factors for cardiovascular disease are now significant in all populations. At least one-third of all CVD is attributable to five risk factors: tobacco use, alcohol use, high blood pressure, high cholesterol and obesity. Methods: This article aspires to collate data gathered by relevant studies conducted after year 2000 and provide an overview of the prevalence of CVD in India and worldwide. Results: Studies show an increased prevalence of cardiovascular risk factors in India as compared to other developing and developed countries with recent trends showing incidence in younger age group. It is seen to affect almost all sections of the society from young to old and most affluent to least affluent. High blood pressure, high cholesterol, tobacco and alcohol use, as well as low vegetable and fruit intake, already figure among the top risk factors. Conclusion: The prevalence of risk factors associated with CVD has increased and will keep on increasing in India as indicated by studies in the last decade and as predicted by the projections for future estimates. Some major risks are modifiable in that they can be prevented, treated, and controlled. There are considerable health benefits at all ages, for both men and women, in stopping smoking, reducing cholesterol and blood pressure, eating a healthy diet and increasing physical activity.

2857 Health Promotion Program on Prevention of Zoonotic Diseases among Aborigines in Peninsular Malaysia

Authors: Siti Fatimah Kader Maideen, Abdul Rashid, Nur Indah Ahmad

Abstract:

Introduction: Indigenous people have an increased risk of contracting zoonotic infections due to their practices. Similarly, the aborigines in Peninsular Malaysia, the Orang Asli, have a higher risk too. This study aimed to empower the Jahai children on the prevention of zoonotic infections by implementing a health promotion intervention program. Methods: A non-experimental pre and post-test interventional study was conducted among the indigenous primary school children aged between nine and 12 years in Perak, Malaysia. A structured questionnaire was used to assess the pre-and post-knowledge and attitudes towards zoonotic infections and hand hygiene practice. This is followed by three sessions of the health promotion program. Ethical approval was obtained prior to the data collection. Data were analysed using SPSS software. Results: The knowledge on whether diseases can spread from animals to humans, transmission via saliva and faeces, types of organisms that can infect, and signs and symptoms increased significantly between pre and post. Significant improvements were observed in the attitude and practices too. Conclusion: The intervention program demonstrated improvement in the knowledge, attitude, and practice among the children. The continuous program needs to be conducted for a sustainable outcome.

2856 A Rapid Colorimetric Assay for Direct Detection of Unamplified Hepatitis C Virus RNA Using Gold Nanoparticles

Authors: M. Shemis, O. Maher, G. Casterou, F. Gauffre

Abstract:

Hepatitis C virus (HCV) is a major cause of chronic liver disease with a global 170 million chronic carriers at risk of developing liver cirrhosis and/or liver cancer. Egypt reports the highest prevalence of HCV worldwide. Currently, two classes of assays are used in the diagnosis and management of HCV infection. Despite the high sensitivity and specificity of the available diagnostic assays, they are time-consuming, labor-intensive, expensive, and require specialized equipment and highly qualified personal. It is therefore important for clinical and economic terms to develop a low-tech assay for the direct detection of HCV RNA with acceptable sensitivity and specificity, short turnaround time, and cost-effectiveness. Such an assay would be critical to control HCV in developing countries with limited resources and high infection rates, such as Egypt. The unique optical and physical properties of gold nanoparticles (AuNPs) have allowed the use of these nanoparticles in developing simple and rapid colorimetric assays for clinical diagnosis offering higher sensitivity and specificity than current detection techniques. The current research aims to develop a detection assay for HCV RNA using gold nanoparticles (AuNPs). Methods: 200 anti-HCV positive samples and 50 anti-HCV negative plasma samples were collected from Egyptian patients. HCV viral load was quantified using m2000rt (Abbott Molecular Inc., Des Plaines, IL). HCV genotypes were determined using multiplex nested RT- PCR. The assay is based on the aggregation of AuNPs in presence of the target RNA. Aggregation of AuNPs causes a color shift from red to blue. AuNPs were synthesized using citrate reduction method. Different sets of probes within the 5’ UTR conserved region of the HCV genome were designed, grafted on AuNPs and optimized for the efficient detection of HCV RNA. Results: The nano-gold assay could colorimetrically detect HCV RNA down to 125 IU/ml with sensitivity and specificity of 91.1% and 93.8% respectively. The turnaround time of the assay is < 30 min. Conclusions: The assay allows sensitive and rapid detection of HCV RNA and represents an inexpensive and simple point-of-care assay for resource-limited settings.

2855 Dietary Quality among U.S. Adults with Diabetes, Osteoarthritis, and Rheumatoid Arthritis: Age-Specific Associations from NHANES 2011-2022

Authors: Oluwafunmibi Omotayo Fasanya, Augustine Kena Adjei

Abstract:

Limited research has examined the variations in dietary quality among U.S. adults diagnosed with chronic conditions like diabetes mellitus (DM), osteoarthritis (OA), and rheumatoid arthritis (RA), particularly across different age groups. Understanding how diet differs in relation to these conditions is crucial to developing targeted nutritional interventions. This cross-sectional study analyzed data from adult participants in the National Health and Nutrition Examination Survey (NHANES) between 2011 and 2021. Dietary quality was measured using the Healthy Eating Index (HEI)-2015 scores, encompassing both total and component scores for different dietary factors. Self-reported disease statuses for DM, OA, and RA were obtained, with age groups stratified into younger adults (20–59 years, n = 10,050) and older adults (60 years and older, n = 5,200). Logistic regression models, adjusted for demographic factors like sex, race/ethnicity, education, income, weight status, physical activity, and smoking, were used to examine the relationship between disease status and dietary quality, accounting for NHANES' complex survey design. Among younger adults, 8% had DM, 10% had OA, and 4% had RA. Among older adults, 22% had DM, 35% had OA, and 7% had RA. The results showed a consistent association between excess added sugar intake and DM in both age groups. In younger adults, excess sodium intake was also linked to DM, while low seafood and plant protein intake was associated with a higher prevalence of RA. Among older adults, a poor overall dietary pattern was strongly associated with RA, while OA showed varying associations depending on the intake of specific nutrients like fiber and saturated fats. The dietary quality of U.S. adults with DM, OA, and RA varies significantly by age group and disease type. Younger adults with these conditions demonstrated more specific dietary inadequacies, such as high sodium and low protein intake, while older adults exhibited a broader pattern of poor dietary quality, particularly in relation to RA. These findings suggest that personalized nutritional strategies are needed to address the unique dietary challenges faced by individuals with chronic conditions in different age groups.

2854 The Application of Transcranial Direct Current Stimulation (tDCS) Combined with Traditional Physical Therapy to Address Upper Limb Function in Chronic Stroke: A Case Study

Authors: Najmeh Hoseini

Abstract:

Strokerecovery happens through neuroplasticity, which is highly influenced by the environment, including neuro-rehabilitation. Transcranial direct current stimulation (tDCS) may enhance recovery by modulating neuroplasticity. With tDCS, weak direct currents are applied noninvasively to modify excitability in the cortical areas under its electrodes. Combined with functional activities, this may facilitate motor recovery in neurologic disorders such as stroke. The purpose of this case study was to examine the effect of tDCS combined with 30 minutes of traditional physical therapy (PT)on arm function following a stroke. A 29-year-old male with chronic stroke involving the left middle cerebral artery territory went through the treatment protocol. Design The design included 5 weeks of treatment: 1 week of traditional PT, 2 weeks of sham tDCS combined with traditional PT, and 2 weeks of tDCS combined with traditional PT. PT included functional electrical stimulation (FES) of wrist extensors followed by task-specific functional training. Dual hemispheric tDCS with 1 mA intensity was applied on the sensorimotor cortices for the first 20 min of the treatment combined with FES. Assessments before and after each treatment block included Modified Ashworth Scale, ChedokeMcmaster Arm and Hand inventory, Action Research Arm Test (ARAT), and the Box and Blocks Test. Results showed reduced spasticity in elbow and wrist flexors only after tDCS combination weeks (+1 to 0). The patient demonstrated clinically meaningful improvements in gross motor and fine motor control over the duration of the study; however, components of the ARAT that require fine motor control improved the greatest during the experimental block. Average time improvement compared to baseline was26.29 s for tDCS combination weeks, 18.48 s for sham tDCS, and 6.83 for PT standard of care weeks. Combining dual hemispheric tDCS with the standard of care PT demonstrated improvements in hand dexterity greater than PT alone in this patient case.

2851 Exploring the Influence of Culture on Dietary Practices and Ethnic Inequality in Health among Migrant Nigerians in the UK

Authors: Babatunde Johnson

Abstract:

The rate of diseases and death from preventable diseases among ethnic minority groups is high when compared with the wider white population in the UK. This can be due in part to the diet consumed and various cultural reasons. Changes in dietary practices and the health of ethnic minority groups can be caused by the adoption of food practices of the host culture after migration (acculturation) and generational differences among migrants. However, understanding how and why these changes occur is limited due to the challenges of data collection in research. This research utilizes the interpretive phenomenological approach, coupled with Bourdieu’s theory used as the conceptual framework, and seeks an in-depth understanding of how adult immigrant Nigerians in the UK interpret their experience of the influence of ethnic and prevailing cultures on their dietary practice. Recruiting participants from a close-knit community, such as the Nigerian population in the UK, can be complex and problematic and is determined by the accessibility to the community. Although complex, the researcher leveraged the principles of Patient and Public Involvement (PPI) in gaining access to participants within the Nigerian community. This study emphasizes the need for a culturally tailored and community-centered approach to interventions geared toward the reduction of ethnic health inequality in the UK other than the existing practice, which focuses on better healthy eating through the improvement of skills and knowledge about food groups.

2850 On the Absence of BLAD, CVM, DUMPS and BC Autosomal Recessive Mutations in Stud Bulls of the Local Alatau Cattle Breed of the Republic of Kazakhstan

Authors: Yessengali Ussenbekov, Valery Terletskiy, Orik Zhanserkenova, Shynar Kasymbekova, Indira Beyshova, Aitkali Imanbayev, Almas Serikov

Abstract:

Currently, there are 46 hereditary diseases afflicting cattle with known molecular genetic diagnostic methods developed for them. Genetic anomalies frequently occur in the Holstein cattle breeds from American and Canadian bloodlines. The data on the incidence of BLAD, CVM, DUMPS and BC autosomal recessive lethal mutations in pedigree animals are discordant, the detrimental allele incidence rates are high for the Holstein cattle breed, whereas the incidence rates of these mutations are low in some breeds or they are completely absent. Data were obtained on the basis of frozen semen of stud bulls. DNA was extracted from the semen with the DNA-Sorb-B extraction kit. The lethal mutation in the genes CD18, SLC35A3, UMP and ASS of Alatau stud bulls (N=124) was detected by polymerase chain reaction and RFLP analysis. It was established that stud bulls of the local Alatau breed were not carriers of the BLAD, CVM, DUMPS, and BC detrimental mutations. However, with a view to preventing the dissemination of hereditary diseases it is recommended to monitor the pedigree stock using molecular genetic methods.

2849 Role of Human Milk Oligosaccharides (HMOs) in Epigenetic Modulation of Bacterial Pathogen in Infant and Toddler

Authors: Aftab Yusuf Raj

Abstract:

Human milk oligosaccharides (HMOs) are complex carbohydrates. They are 3rd most abundant solid component found in breast milk, after lactose and lipids. HMO has profound beneficial health benefit effects on infants and toddlers. They have diverse roles, in immuno-modulation, development of neonatal gut, influencing the commensal microbiota of developing gut, and anti-inflammatory functions. HMOs, gut and commensal microbiota of the gut work synergistically to bring positive impact on infant and toddler health. HMO influences the gut-brain axis, maintains good mental health and cognitive function and inhibits neuronal inflammation. HMOs are now applied in infant nutrition, and supplementation of HMOs in infant formula is a promising innovation for infant nutrition.

2848 Increased Risk of Adverse Birth Outcomes of Newborns in Arsenic Exposed- Women with Gestational Diabetes

Authors: Tania Mannan, Rahelee Zinnat, Fatema Jebunnesa, Israt Ara Hossain

Abstract:

Background: Exposure to arsenic has known toxic effects but the effect on pregnancy outcomes is not as widely documented especially in women with diabetes. Growing evidence has suggested a potential role of arsenic exposure in the development of gestational diabetes mellitus (GDM). Therefore, we aimed to investigate the association of urinary arsenic (UAs) with birth outcomes in GDM subjects. Methods: Under an observational cross-sectional design a total of 263 GDM subjects (age in years, M±SD, 21±3.7) residing in an arsenic affected area of Bangladesh, were subjected to a 2 sample OGTT at the third trimester of gestation. Among them, 73 GDM and 190 non-GDM subjects enrolled in this study. Clinical and anthropometric measurements were done by standard techniques. Degree of chronic arsenic exposure was assessed by the level of UAs level. According to World Health Organization (WHO) criteria, GDM was diagnosed and neonatal outcomes using APGAR (Activity Pulse Grimace Appearance Respirations) Score, birth weight and size were assessed by a specialist obstetrician. Serum glucose was measured by the Glucose Oxidase method and UAs level was determined by ultraviolet/visible spectrophotometry. Result: Out of the 263 pregnant women, 28% developed GDM. Urinary Arsenic was significantly higher in the GDM as compared to the non-GDM group [UAs, µg/l, M±SD (range), 204.2±67.0 (67.0-377.0) vs 77.3±38.1 (22.0-99.0), p < 0.001]. Activity Pulse Grimace Appearance Respirations Score of the neonates from GDM mothers was significantly lower compared to the neonates from non-GDM mothers [APGAR Score, M±SD, 4.7±0.8 vs. 6.4±0.7, p<0.001]. Pearson’s correlation analysis in GDM subjects revealed that UA levels were found to have a significant positive correlation with both fasting and postprandial serum glucose levels (p < 0.001) and (p < 0.001) respectively. Again, a significant inverse correlation of UAs with birth weight and size was observed (p < 0.001). The APGAR Score of the neonates were found to have a significant negative correlation (p < 0.001) with UAs level. Conclusion: The effect of chronic arsenic exposure is associated with glucose intolerance during pregnancy and it also adversely affects birth outcomes. The study suggests further research on the impact of total arsenic exposure on pregnancy outcomes.

2847 The Diffusion of Membrane Nanodomains with Specific Ganglioside Composition

Authors: Barbora Chmelova, Radek Sachl

Abstract:

Gangliosides are amphipathic membrane lipids. Due to the composition of bulky oligosaccharide chains containing one or more sialic acids linked to the hydrophobic ceramide base, gangliosides are classified among glycosphingolipids. This unique structure induces a high self-aggregating tendency of gangliosides and, therefore, the formation of nanoscopic clusters called nanodomains. Gangliosides are preferentially present in an extracellular membrane leaflet of all human tissues and thus have an impact on a huge number of biological processes, such as intercellular communication, cell signalling, membrane trafficking, and regulation of receptor activity. Defects in their metabolism, impairment of proper ganglioside function, or changes in their organization lead to serious health conditions such as Alzheimer´s and Parkinson´s diseases, autoimmune diseases, tumour growth, etc. This work mainly focuses on ganglioside organization into nanodomains and their dynamics within the plasma membrane. Current research investigates static ganglioside nanodomains characterization; nevertheless, the information about their diffusion is missing. In our study, fluorescence correlation spectroscopy is implemented together with stimulated emission depletion (STED-FCS), which combines the diffraction-unlimited spatial resolution with high temporal resolution. By comparison of the experiments performed on model vesicles containing 4 % of either GM1, GM2, or GM3 and Monte Carlo simulations of diffusion on the plasma membrane, the description of ganglioside clustering, diffusion of nanodomains, and even diffusion of ganglioside molecules inside investigated nanodomains are described.

Authors: Shizra Waris, Bilal Shoaib, Munib Ahmad

Abstract:

Background; The using of clinical decision support systems (CDSSs) may recover unceasing disease organization, which requires regular visits to multiple health professionals, treatment monitoring, disease control, and patient behavior modification. The objective of this survey is to determine if these CDSSs improve the processes of unceasing care including diagnosis, treatment, and monitoring of diseases. Though artificial intelligence is not a new idea it has been widely documented as a new technology in computer science. Numerous areas such as education business, medical and developed have made use of artificial intelligence Methods: The survey covers articles extracted from relevant databases. It uses search terms related to information technology and viral hepatitis which are published between 2000 and 2016. Results: Overall, 80% of studies asserted the profit provided by information technology (IT); 75% of learning asserted the benefits concerned with medical domain;25% of studies do not clearly define the added benefits due IT. The CDSS current state requires many improvements to hold up the management of liver diseases such as HCV, liver fibrosis, and cirrhosis. Conclusion: We concluded that the planned model gives earlier and more correct calculation of hepatitis B and it works as promising tool for calculating of custom hepatitis B from the clinical laboratory data.

2845 A 30 Year Audit of the Vascular Complications of Ports: Permanent Intravascular Access Devices

Authors: S. Kershaw, P. J. Barry, K. Webb

Abstract:

Background: Cystic Fibrosis (CF) is a chronic lung disease where patients have chronic lung infection punctuated by acute exacerbations that require intermittent intravenous (IV) antibiotics during their lives. With time, peripheral venous access can become difficult and limited. Accessing these veins can become arduous, traumatic, painful and unworkable. A permanent intravascular access device or Port is a small device that is inserted into the central venous system that allows the delivery of medicine eliminating the need for peripheral venous access. Ports represent a convenient and efficient method when venous access is required on a permanent basis however they are also associated with significant vascular complications. Superior Vena Cava Obstruction (SVCO) is a rare but significant vascular complication of ports in this setting. Objective: We aimed to look at a single CF centre’s experience of port-related SVCO over a thirty year period. Methods: Retrospective data was extracted using patient’s notes, electronic radiological reports and local databases over a period in excess of 30 years from 1982 to 2014. Results: 13 patients were identified with SVCO as a result of their port. 11 patients had CF (9 female, 2 male), one male patient had Primary Ciliary Dyskinesia and one female patient had severe Asthma. The mean port function was 1532 days (range 110 – 4049) and the mean age at SVCO was 24 years (range 11.1 to 36.5 years). The most common symptoms were facial oedema (n=8, 61.5%) and dilated veins (n=6, 46.2%). 7 patients had their Ports removed after SVCO. 6 patients underwent attempted stenting (46.2%) and 6 did not. 4 out of the 6 who underwent stenting required/had re-intervention. 3 of the 6 patients who underwent stenting had symptom resolution, however, 4 of the 6 patients who were not stented had symptom resolution also. Symptom resolution was not guaranteed with stenting and required re-intervention in two-thirds. Conclusion: This case series represents the experience of one of the longest established CF units in the UK and represents the largest cohort ever reported in the literature.

Authors: Ayubova Nargiza Mirzabixulaevna, Kiryakov Dmitriy Andreyevich

Abstract:

Relevance: According to experts from the World Health Organization, in 80% of cases, the causes of skin cancer are external factors: polluted air, radioactive substances, solar flares, and free radicals. In dermatology, one of the most common related to obligate diseases is actinic keratosis. Actinic keratosis (AC) is an area of abnormal proliferation and differentiation of keratinocytes, which carry the risk of progression into invasive squamous cell carcinoma of the skin. The purpose of the study is to study the prevalence of various forms of actinic keratosis among the population of Uzbekistan. Materials and methods of research: The study is based on the observation and clinical laboratory examination of 96 patients who were divided by gender and age. Women made up 45% and men made up 55%. The youngest patient was 43 years old, and the oldest was 92 years old. The control group consisted of 40 patients. The following clinical signs were evaluated: peeling, hyperkeratosis, erythema, pigmentation, atrophy. Results: Studies have shown that of all forms of actinic keratosis, erythematous (36%), hyperkeratotic (27%), pigmented (12%), cutaneous horn (7.0%), atrophic (7.0%), Actinic cheilitis (6%), lichenoid (5%) are common. Conclusion: Thus, the data we have obtained indicate that the main and pronounced clinical sign in the erythematous form is erythema and the hyperkeratic form is often found. With cutaneous horn, there is a sharp hyperkeratosis of the epidermis.

2842 Digitial Communication – The Future of Chronic Disease Management Is Healthcare Apps

Authors: Kirstin Griffin

Abstract:

During a period of increased anxiety and stress, communication became the essential tool to help the public stay informed and feel prepared during the Covid-19 pandemic. However, certain groups of patients were not feeling as reassured. The news and media blasted the message that patients with diabetes were “high-risk" in regards to contracting the Covid-19 infection. Routine clinics were being cancelled, GP practices were closing their doors, and patients with type 1 diabetes were understandably scared. The influx of calls to diabetes specialists nurses from concerned patients highlighted the need for better and more specialised information. An Application specifically for patients with type 1 diabetes was created to deliver this information, and it proved to be the essential communication tool that was desperately needed. The Application for patients with type 1 diabetes aimed to deliver specialist information to patients in regards to their diagnosis, management, and ongoing follow-up commitments. The Application gives practical advice on multiple areas of diabetes management, including sick-day rules and diabetic emergencies, as well as up-to-date information on technology, including setting up Libre devices and downloading glucose meters to facilitate attending virtual clinics. Delivery of this information in an easy-to-understand and comprehensive way is intended to improve patient engagement with diabetes services and ultimately empower patients in the control of their own disease. The application also offers a messaging service to allow the diabetes team to send out alerts to patient groups on specific issues, such as changes to clinics, or respond to recent news updates regarding Covid-19. The App was launched in NHS Fife in June 2020 and has amassed 800 active users so far. There is growing engagement with the App since its launch, with over 1000 user interactions in the last month alone. Feedback shows that 100% of users like the App and have found it useful in the management of their diabetes. The App has proven to be an essential tool in communication with one of the most vulnerable groups during the Covid-19 pandemic, and its ongoing development will continue to increase patient engagement and improve glycaemic control for patients with type 1 diabetes. The future of chronic disease management should involve digital solutions such as apps to further empower patients in their healthcare.

Authors: Cangir Uyarlar, Eyup Eren Gultepe, Mustafa Kabu, Hacı Ahmet Celik

Abstract:

This study aimed to evaluate the effects of orally Immunoglobulin (Ig) Y treatments to calves were fed with colostrum having insufficient antibodies before first suckling. A total of 28 Holstein calves were fed assigned into control and treatment groups. The calves were fed fresh colostrum from their respective mother for the first 4 days. The treatment group calves were orally administered IgLock (10 g/d/calf) immediately before the first colostrum feeding and IgLock was administered just one time in treatment group calves. Then, the calves were offered normal milk until weaning. After weaning, all calves kept same paddock and were fed same ration. Diarrhea and respiratoric diseases were recorded for one year. Blood was collected from all calves in the study on birth day (0 day) before vaccination and IgLock administration, then, collected for the following 2 days in all groups. Albumin (ALB), Total Protein (TP), Aspartate Aminotransferase (AST), Alanine Aminotrasferase (ALT), Gamma-Glutamyl Transferase (GGT), Serum Amyloid A (SAA), Haptoglobin (HPT) and Ig G analyses were performed on all samples. Although serum ALB, ALT, GGT and Ig G levels were not shown a time dependent-change within control group; serum TP, AST, HPT and SAA levels were significantly changed by the time within mentioned group. Serum TP level was steady at first 2 days, then, it was increased significantly at 3rd day. Also, serum AST level was significantly increased at 2nd day, then it was descended to first day levels again at 3rd day. Although serum HPT levels were shown a significant gradually decreasing within control group, serum SAA levels were decreased rapidly after first day and there were no significance differences between 2nd and 3rd day in SAA levels. Serum ALB, ALT, HPT and SAA levels were not shown a time dependent-change within treatmet group. After first day Serum TP, GGT, AST and Ig G levels were shown an significant increasing at 2nd day.

Authors: A. Qasmaoui, F. Ohmani, Z. Zaine, I. El Akrad, J. Hamamouchi, K. Halout, B. Belkadi, R. Charof

Abstract:

The evolution of antibiotic resistance is a crucial aspect of the problem related to the intensive use of these substances in medicine for humans and animals. The production of ESBL extended spectrum β-lactamase enzymes is the main mechanism of resistance to β-lactam antibiotics in Escherichia coli. The objective of our work is to determine the resistance genes in E. coli strains.ESBL coli stored at the epidemic diseases laboratory of the National Institute of Hygiene. The strains were identified according to the classic bacteriological criteria. An antibiogram was performed on the strains isolated by the Mueller Hinton agar disc diffusion method. The production of ESBL in the strains was detected by the synergy assay technique and confirmed for the presence of the blaCTX-M1, blaCTX-M2, blaTEM, blaSHV, blaOXA-48 genes by gene amplification . Of the 27 observed strains of E.coli, 17 isolated strains present the phenotype of extended-spectrum Beta-lactamase with a percentage of 63%.. All 18 cefotaxime-resistant strains were analyzed for an ESBL phenotype. All strains were positive in the double-disc synergy assay. The fight against the emergence and spread of these multi-resistant antibiotic-resistant strains requires the reasonable use of antibiotics.

2838 Physico-Chemical and Antibacterial Properties of Neem Extracts

Authors: C. C. Igwe

Abstract:

Several parts of Neem tree (Azadirachta indica) are used in traditional medicine in many West African countries for the treatment of various human diseases. The leaf, stem - bark and seed were air dried for 8, 5 and 7 days, respectively. The shells were carfully separated from the seeds, each powdered sample obtained with mechanical miller and 250 mm sieve. The neem samples were individually subjected to extraction with acetone, n-hexane for 48hr and 72 hr, respectively. Physico-chemical and antibacterial evaluation were carried out using standard methods. Results of physico - chemical analyses of the extracted oil from the seed shows that it has a brownish colour, with a smell similar to garlic while the moisture content, refractive index are 0.76% and 1.47 respectively. Other vital chemical results obtained from the neem oil such as saponification value (234.62), acid value (10.84 %), free fatty acid (5.84 %) and peroxide value (10.52%) indicated the oil extracted satisfied standard oils parameters for quality soap and cosmetics production. The antibacterial screening by disc diffusion revealed the oil demonstrated high activity against Staphylococcus aureus. Both the physio-chemical and antibacterial of samples have been certified by National Agency for Food and Drugs Administration and Control. The preliminary results of this study may validate the medicinal value of the plant. Further studies are in progress to clarify the in vivo potentials of neem extracts in the management of human communicable diseases and this is a subject of investigation in our group.

Authors: Maria Lopez-Ibarra, Ana Velazquez-Wong, Lucelli Yañez-Gutierrez, Maria Araujo-Solis, Fabio Salamanca-Gomez, Alfonso Mendez-Tenorio, Haydeé Rosas-Vargas

Abstract:

Congenital heart diseases (CHD) are the most common congenital abnormalities. These conditions can occur as both an element of distinct chromosomal malformation syndromes or as non-syndromic forms. Their etiology is not fully understood. Genetic variants such copy number variants have been associated with CHD. The aim of our study was to analyze these genomic variants in peripheral blood from Mexican children diagnosed with non-syndromic CHD. We included 16 children with atrial and ventricular septal defects and 5 healthy subjects without heart malformations as controls. To exclude the most common heart disease-associated syndrome alteration, we performed a fluorescence in situ hybridization test to identify the 22q11.2, responsible for congenital heart abnormalities associated with Di-George Syndrome. Then, a microarray based comparative genomic hybridization was used to identify global copy number variants. The identification of copy number variants resulted from the comparison and analysis between our results and data from main genetic variation databases. We identified copy number variants gain in three chromosomes regions from pediatric patients, 4q13.2 (31.25%), 9q34.3 (25%) and 20q13.33 (50%), where several genes associated with cellular, biosynthetic, and metabolic processes are located, UGT2B15, UGT2B17, SNAPC4, SDCCAG3, PMPCA, INPP6E, C9orf163, NOTCH1, C20orf166, and SLCO4A1. In addition, after a hierarchical cluster analysis based on the fluorescence intensity ratios from the comparative genomic hybridization, two congenital heart disease groups were generated corresponding to children with atrial or ventricular septal defects. Further analysis with a larger sample size is needed to corroborate these copy number variants as possible biomarkers to differentiate between heart abnormalities. Interestingly, the 20q13.33 gain was present in 50% of children with these CHD which could suggest that alterations in both coding and non-coding elements within this chromosomal region may play an important role in distinct heart conditions.

Authors: Zoran Herceg, Višnja Stulić, Tomislava Vukušić, Anet Režek Jambrak

Abstract:

High voltage electrical discharge is a new technology used for inactivation of pathogen microorganisms. Pathogen yeasts can cause diseases in humans if they are ingested. Nowadays new technologies have become the focus of researching all over the world. Rhodotorula is known as yeast that can cause diseases in humans. The aim of this study was to examine whether the high voltage electrical discharge treatment generated in gas phase has an influence on yeast reduction and recovery of Rhodotorula spp 74 in pure culture. Rhodotorula spp. 74 was treated in 200 mL of model solution. Treatment time (5 and 10 min), frequency (60 and 90 Hz) and injected gas (air or argon 99,99%) were changed. Titanium high voltage needle was used as high voltage electrode (positive polarity) through which air or argon was injected at the gas flow of 0.6 L/min. Experimental design and statistical analyses were obtained by Statgraphics Centurion software (StatPoint Technologies, Inc., VA, USA). The best inactivation rate 1.7 log10 reduction was observed after the 10 min of treatment, frequency of 90 Hz and injected air. Also with a longer treatment time inactivation rate was higher. After the 24 h recovery of treated samples was observed. Therefore the further optimization of method is needed to understand the mechanism of yeasts inactivation and cells recovery after the treatment.

Abstract:

Objective: In many countries, tuberculosis (TB) is still one of the most important diseases. Tuberculosis is among top 10 causes of death worldwide. The early diagnosis of active tuberculosis still depends on the presence of acid resistant bacilli (ARB) in stained smears. In this study, we aimed to investigate the diagnostic performances of Erlich Ziehl Neelsen (EZN), Kinyoun and two different fluorescent stains. Methods: The specimens were obtained from the patients who applied to Chest Diseases Departments of Ankara Atatürk Chest Diseases and Thoracic Surgery Training and Research Hospital, and Afyon Kocatepe University, ANS Research and Practice Hospital. The study was carried out in the Medical Microbiology Laboratory, School of Medicine, Afyon Kocatepe University. All the non-sterile specimens were homogenized and decontaminated according to the EUCAST instructions. Samples were inoculated onto the Löwenstein-Jensen agars (bio-Merieux Marcy l'Etoile, France) and then incubated at 37˚C, for 40 days. Four smears were prepared from each specimen. Slides were stained with commercial EZN (BD, Sparks, USA), Kinyoun (SALUBRIS Istanbul, Turkey), Auramine (SALUBRIS Istanbul, Turkey) and Rhodamine (SALUBRIS Istanbul, Turkey) kit. While EZN and Kinyoun stainings were examined by light microscope, Auramine and Rhodamine slides were examined by fluorescence microscopy. Results: A total of 158 respiratory system samples (sputum, broncho alveolar lavage fluid…etc) were enrolled into the study. A hundred and two of the samples that processed were found as culture positive. The sensitivity, specificity, positive predictive, and negative predictive values were detected as 100%, 67.5%, 73.5%, and 100% for EZN, 100%, 70.9%, 77.4%, and 100% for Kinyoun, 100%,77.8%, 84.3%, 100% for Auramine, and 100%, 80% , 86.3%, and 100% for Rhodamine respectively. Conclusions: According to our study auramine and rhodamine staining methods showed the best diagnostic performance among the four investigated staining methods. In conclusion, the fluorochrome staining method may be accepted as the most reliable, rapid and useful method for diagnosis of the mycobacterial infections truly.

2834 Clustering of Natural and Nature Derived Compounds for Cardiovascular Disease: Pharmacophore Modeling

Authors: S. Roy, R. Rekha, K. Sriram, G. Subhadra, R. Johana

Abstract:

Cardiovascular disease remains a leading cause of death in most industrialized countries. Many chemical drugs are available in the market which targets different receptor proteins related to cardiovascular diseases. Of late the traditional herbal drugs are safer when compared to chemical drugs because of its side effects. However, many herbal remedies used in treating cardiovascular diseases have not undergone scientific assessment to prove its pharmacological activities. There are many natural compounds, nature derived and Natural product mimic compounds are available which are in the market as approved drug. In the most of the cases drug activity at the molecular level are not known. Here we have categorized those compounds with our experimental compounds in different classes based on the structural similarity and physicochemical properties, using a tool, Chemmine and has attempted to understand the mechanism of the action of a experimental compound, which are clustered with Simvastatin, Lovastatin, Mevastatin and Pravastatin. Target protein molecule for Simvastatin, Lovastatin, Mevastatin and Pravastatin is HMG-CoA reductase, so we concluded that the experimental compound may be able to bind to the same target. Molecular docking and atomic interaction studies with simvastatin and our experimental compound were compared. A pharmacophore modeling was done based on the experimental compound and HMG-CoA reductase inhibitor.

2833 Identification and Characterization of Genes Expressed in Diseased Condition Silkworms (Bombyx mori): A Systematic Investigation

Authors: Siddharth Soni, Gourav Kumar Pandey, Sneha Kumari, Dev Mani Pandey, Koel Mukherjee

Abstract:

The silkworm Bombyx mori is a commercially important insect, but a major roadblock in silk production are silkworm diseases. Flacherie is one of the diseases of the silkworm, that affects the midgut of the 4th and 5th instar larvae and eventually makes them lethargic, stop feeding and finally result in their death. The concerned disease is a result of bacterial and viral infection and in some instances a combination of both. The present study aims to identify and study the expression level of genes in the flacherie condition. For the said work, total RNA was isolated from the infected larvae at their most probable infectious instar and cDNA was synthesized using Reverse Transcriptase PCR (RT-PCR). This cDNA was then used to amplify disease relalted genes whose expression levels were checked using quantitaive PCR (qPCR) using the double delta Ct method. Cry toxin receptors like APN and BtR-175, ROS mediator Dual Oxidase are few proteins whose genes were overexpressed. Interestingly, pattern recognition receptors (PRRs) C-type lectins' genes were found to be downregulated. The results explain about the strong expression of genes that can distinguish the concerned protein in the midgut of diseased silkworm and thereby aiding knowledge in the field of inhibitor designing research.

2832 Sumac Sprouts: From in Vitro Seed Germination to Chemical Characterization

Authors: Leto Leandra, Guaitini Caterina, Agosti Anna, Del Vecchio Lorenzo, Guarrasi Valeria, Cirlini Martina, Chiancone Benedetta

Abstract:

To the best of our knowledge, this study represents the first attempt to investigate the in vitro germination response of Rhus coriaria L., and its sprout chemical characterization. Rhus coriaria L., a species belonging to the Anacardiaceae family, is commonly called "sumac" and is cultivated, in different countries of the Mediterranean and the Middle East regions, to produce a spice with a sour taste, obtained from its dried and ground fruits. Moreover, since ancient times, many beneficial properties have been attributed to this plant that has been used, in the traditional medicine of several Asian countries, against various diseases, including liver and intestinal pathologies, ulcers and various inflammatory states. In the recent past, sumac was cultivated in the Southern regions of Italy to treat leather, but its cultivation was abandoned, and currently, sumac plants grow spontaneously in marginal areas. Recently, in Italy, the interest in this species has been growing again, thanks to its numerous properties; thus, it becomes imperative to deepen the knowledge of this plant. In this study, in order to set up an efficient in vitro seed germination protocol, sumac seeds collected from spontaneous plants grown in Sicily, an island in the South of Italy, were, firstly, subjected to different treatments, scarification (mechanical, physical and chemical), cold stratification and imbibition, to break their physical and physiological dormancy, then, treated seeds were in vitro cultured on media with different gibberellic acid (GA3) concentrations. Results showed that, without any treatment, only 5% of in vitro sown seeds germinated, while the germination percentage increased up to 19% after the mechanical scarification. A further significative improvement of germination percentages was recorded after the physical scarification, with (40.5%) or without (36.5%) 8 weeks of cold stratification, especially when seeds were sown on gibberellin enriched cultured media. Vitro-derived sumac sprouts, at different developmental stages, were chemically characterized, in terms of polyphenol and tannin content, as well as for their antioxidant activity, to evaluate this matrix as a potential novel food or as a source of bioactive compounds. Results evidenced how more developed sumac sprouts and, above all, their leaves are a wealthy source of polyphenols (78.4 GAE/g SS) and tannins (21.9 mg GAE/g SS), with marked antioxidant activity. The outcomes of this study will be of support the nursery sector and sumac growers in obtaining a higher number of plants in a shorter time; moreover, the sprout chemical characterization will contribute to the process of considering this matrix as a new source of bioactive compounds and tannins to be used in food and non-food sectors.

2830 Polymer Nanocarrier for Rheumatoid Arthritis Therapy

Authors: Vijayakameswara Rao Neralla, Jueun Jeon, Jae Hyung Park

Abstract:

To develop a potential nanocarrier for diagnosis and treatment of rheumatoid arthritis (RA), we prepared a hyaluronic acid (HA)-5β-cholanic acid (CA) conjugate with an acid-labile ketal linker. This conjugate could self-assemble in aqueous conditions to produce pH-responsive HA-CA nanoparticles as potential carriers of the anti-inflammatory drug methotrexate (MTX). MTX was rapidly released from nanoparticles under inflamed synovial tissue in RA. In vitro cytotoxicity data showed that pH-responsive HA-CA nanoparticles were non-toxic to RAW 264.7 cells. In vivo biodistribution results confirmed that, after their systemic administration, pH-responsive HA-CA nanoparticles selectively accumulated in the inflamed joints of collagen-induced arthritis mice. These results indicate that pH-responsive HA-CA nanoparticles represent a promising candidate as a drug carrier for RA therapy.
