A Pilot Study on Anti-Diabetic Effect of Vestibular Stimulation in Alloxan Induced Diabetic Model of Wistar Albino Rats

ABSTRACT The present study was undertaken to observe efficacy of vestibular stimulation in diabetes care. Diabetes was induced in the rats by injecting alloxan intraperitonially (I.P) in a single dose of 150mg/kg of body weight. Vestibular stimulation was performed for 60 days by caloric vestibular stimulation, by instilling warm (40 o c) and cold water (30 o c) into the external auditory meatus for group 3 and 4 respectively. The temperature difference sets up convection currents in the endolymph, with consequent motion of the cupula. Blood glucose estimation was performed by using one touch glucometer. In our pilot study we didn't observe significant effect of hot water vestibular stimulation on blood glucose levels . However cold water vestibular stimulation significantly decreased blood glucose levels on 30 th and 40 th day in alloxan induced diabetes rats. Cold water vestibular stimulation may be effective for diabetic patients. Major limitation of our study was low sample size. Hence we suggest further detailed study with more parameters to explode the effectiveness of vestibular stimulation in diabetic care

Effect of Forced Freshwater and Cold Water Swimming Stress Induced Changes in Selected Physiological and Biochemical Parameters in Wistar Albino Rats

ABSTRACT The objective of the present study was to observe the effect of cold water and fresh water swimming stress on physiological and biochemical parameters. 42 adult male 'albino rats of wistar strain with body weight ranging between (50-125g) were subjected to fresh water and cold water swimming stress. The body weight was measured before and after the stress period in all the rats. The animals were sacrificed by decapitation and blood samples were collected. The wet weight of the organs (heart, right and left kidneys, liver, spleen) was expressed per 100g of body weight. Total leucocyte count, red blood cell count, Platelet count, and Hemoglobin were estimated by standard physiological methods. Blood sugar level and serum total cholesterol level were measured by colorimetric method. We conclude that body weight, liver weight, spleen weight increased significantly followed by cold water swimming stress. Significant hypoglycemia was observed followed by both Fresh water and cold water swimming stress. Platelet count decreased significantly followed by both Fresh water and cold water swimming stress. Total leucocyte count increased significantly followed by Fresh water swimming stress

Tetralogy of Fallot with rheumatic mitral stenosis: A case report

<p>Abstract</p> <p>Introduction</p> <p>Rheumatic and congenital heart diseases account for the majority of hospital admissions for cardiac patients in India. Tetralogy of Fallot is the most common congenital heart disease with survival to adulthood. Infective endocarditis accounts for 4% of admissions to a specialized unit for adult patients with a congenital heart lesion. This report is unique in that a severe stenotic lesion of the mitral valve, probably of rheumatic aetiology, was noted in an adult male with Tetralogy of Fallot.</p> <p>Case presentation</p> <p>An unusual association of rheumatic mitral stenosis in an adult Indian male patient aged 35 years with Tetralogy of Fallot and subacute bacterial endocarditis of the aortic valve is presented.</p> <p>Conclusion</p> <p>In this case report the diagnostic implications, hemodynamic and therapeutic consequences of mitral stenosis in Tetralogy of Fallot are discussed. In addition, the morbidity and mortality of infective endocarditis in adult patients with congenital heart disease are summarized. The risk of a coincident rheumatic process in patients with congenital heart disease is highlighted and the need for careful attention to this possibility during primary and follow-up evaluation of such patients emphasized.</p

Change in BMI Accurately Predicted by Social Exposure to Acquaintances

Research has mostly focused on obesity and not on processes of BMI change more generally, although these may be key factors that lead to obesity. Studies have suggested that obesity is affected by social ties. However these studies used survey based data collection techniques that may be biased toward select only close friends and relatives. In this study, mobile phone sensing techniques were used to routinely capture social interaction data in an undergraduate dorm. By automating the capture of social interaction data, the limitations of self-reported social exposure data are avoided. This study attempts to understand and develop a model that best describes the change in BMI using social interaction data. We evaluated a cohort of 42 college students in a co-located university dorm, automatically captured via mobile phones and survey based health-related information. We determined the most predictive variables for change in BMI using the least absolute shrinkage and selection operator (LASSO) method. The selected variables, with gender, healthy diet category, and ability to manage stress, were used to build multiple linear regression models that estimate the effect of exposure and individual factors on change in BMI. We identified the best model using Akaike Information Criterion (AIC) and R[superscript 2]. This study found a model that explains 68% (p<0.0001) of the variation in change in BMI. The model combined social interaction data, especially from acquaintances, and personal health-related information to explain change in BMI. This is the first study taking into account both interactions with different levels of social interaction and personal health-related information. Social interactions with acquaintances accounted for more than half the variation in change in BMI. This suggests the importance of not only individual health information but also the significance of social interactions with people we are exposed to, even people we may not consider as close friends.MIT Masdar ProgramMIT Media Lab Consortiu

Combined effect of regulatory polymorphisms on transcription of UGT1A1 as a cause of Gilbert syndrome

<p>Abstract</p> <p>Background</p> <p>Gilbert syndrome is caused by defects in bilirubin UDP-glucuronosyltransferase (UGT1A1). The most common variation believed to be involved is A(TA)7TAA. Although several polymorphisms have been found to link with A(TA)7TAA, the combined effect of regulatory polymorphisms in the development of Gilbert syndrome remains unclear.</p> <p>Methods</p> <p>In an analysis of 15 patients and 60 normal subjects, we detected 14 polymorphisms and nine haplotypes in the regulatory region. We classified the 4-kbp regulatory region of the patients into: the TATA box including A(TA)7TAA; a phenobarbital responsive enhancer module including c.-3275T>G; and a region including other ten linked polymorphisms. The effect on transcription of these polymorphisms was studied.</p> <p>Results</p> <p>All haplotypes with A(TA)7TAA had c.-3275T>G and additional polymorphisms. In an <it>in-vitro </it>expression study of the 4-kbp regulatory region, A(TA)7TAA alone did not significantly reduce transcription. In contrast, c.-3275T>G reduced transcription to 69% of that of wild type, and the linked polymorphisms reduced transcription to 88% of wild type. Transcription of the typical regulatory region of the patients was 56% of wild type. Co-expression of constitutive androstane receptor (CAR) increased the transcription of wild type by a factor of 4.3. Each polymorphism by itself did not reduce transcription to the level of the patients, however, even in the presence of CAR.</p> <p>Conclusions</p> <p>These results imply that co-operation of A(TA)7TAA, c.-3275T>G and the linked polymorphisms is necessary in causing Gilbert syndrome.</p

State–Space Forecasting of Schistosoma haematobium Time-Series in Niono, Mali

Adequate forecasting and early warning systems are based upon observations of human behavior, population, disease time-series, climate, environment, and/or a combination thereof, whichever option best compromises among realism, feasibility, robustness, and parsimony. Fully automatic and user-friendly state–space forecasting frameworks, incorporating myriad options (e.g., expert opinion, univariate, multivariate, and spatial-temporal), could considerably enhance disease control and hazard mitigation efforts in regions where vulnerability to neglected tropical diseases is pervasive and statistical expertise is scarce. The operational simplicity, generality, and flexibility of state–space frameworks, encapsulating multiple methods, could conveniently allow for 1) unsupervised model selection without disease-specific methodological tailoring, 2) on-line adaptation to disease time-series fluctuations, and 3) automatic switches between distinct forecasting methods as new time-series perturbations dictate. In this investigation, a univariate state–space framework with the aforementioned properties was successfully applied to the Schistosoma haematobium time-series for the district of Niono, Mali, to automatically generate contemporaneous on-line forecasts and hence, providing a basis for local re-organization and strengthening public health programs in this and potentially other Sahelian districts

Apolipoprotein M Gene (APOM) Polymorphism Modifies Metabolic and Disease Traits in Type 2 Diabetes

This study aimed at substantiating the associations of the apolipoproein M gene (APOM) with type 2 diabetes (T2D) as well as with metabolic traits in Hong Kong Chinese. In addition, APOM gene function was further characterized to elucidate its activity in cholesterol metabolism. Seventeen APOM SNPs documented in the NCBI database were genotyped. Five SNPs were confirmed in our study cohort of 1234 T2D and 606 control participants. Three of the five SNPs rs707921(C+1871A), rs707922(G+1837T) and rs805264(G+203A) were in linkage disequilibrium (LD). We chose rs707922 to tag this LD region for down stream association analyses and characterized the function of this SNP at molecular level. No association between APOM and T2D susceptibility was detected in our Hong Kong Chinese cohort. Interestingly, the C allele of rs805297 was significantly associated with T2D duration of longer than 10 years (OR = 1.245, p = 0.015). The rs707922 TT genotype was significantly associated with elevated plasma total- and LDL- cholesterol levels (p = 0.006 and p = 0.009, respectively) in T2D patients. Molecular analyses of rs707922 lead to the discoveries of a novel transcript APOM5 as well as the cryptic nature of exon 5 of the gene. Ectopic expression of APOM5 transcript confirmed rs707922 allele-dependent activity of the transcript in modifying cholesterol homeostasis in vitro. In conclusion, the results here did not support APOM as a T2D susceptibility gene in Hong Kong Chinese. However, in T2D patients, a subset of APOM SNPs was associated with disease duration and metabolic traits. Further molecular analysis proved the functional activity of rs707922 in APOM expression and in regulation of cellular cholesterol content

Who wants a slimmer body? The relationship between body weight status, education level and body shape dissatisfaction among young adults in Hong Kong

Background: Body shape dissatisfaction has been thought to have an indispensable impact on weight control behaviors. We investigated the prevalence of body shape dissatisfaction (BSD) and explored its association with weight status, education level and other determinants among young adults in Hong Kong. Methods. Information on anthropometry, BSD, and socio-demographics was collected from a random sample of 1205 young adults (611 men and 594 women) aged 18-27 in a community-based household survey. BSD was defined as a discrepancy between current and ideal body shape based on a figure rating scale. Cross-tabulations, homogeneity tests and logistic regression models were applied. Results: The percentages of underweight men and women were 16.5% and 34.9% respectively, and the corresponding percentages of being overweight or obese were 26.7% and 13.2% for men and women respectively. Three-quarters of young adults had BSD. Among women, 30.9% of those underweight and 75.5% of those with normal weight desired a slimmer body shape. Overweight men and underweight women with lower education level were more likely to have a mismatch between weight status and BSD than those with higher education level. After controlling for other determinants, underweight women were found to have a higher likelihood to maintain their current body shapes than other women. Men were found to be less likely to have a mismatch between weight status and BSD than women. Conclusions: Overweight and obesity in men and underweight in women were prevalent among Hong Kong young adults. Inappropriate body shape desire might predispose individuals to unhealthy weight loss or gain behaviors. Careful consideration of actual weight status in body shape desire is needed in health promotion and education, especially for underweight and normal weight women and those with a low education level. © 2011 Cheung et al; licensee BioMed Central Ltd.published_or_final_versio
