The Garhwal Himalayas are a part of a unique ecosystem, with sharp agro-climatic variations within a very small geographical area (53,485 km2). The varied agro-climatic situations result in different cropping systems and socio-economic lifestyles that could likely affect the nutritional status of the people living in this region. This article will attempt to explore the impact of these variables (namely, age, family size, education, income, calorie and protein intake, land holding, number of animals, and wheat production) on the body mass index (BMI) of the population residing in the Garhwal Hills. A total of 1,030 subjects were studied from the three agro-climatic zones (406 from the high hills, 292 from the mid hills, and 332 from the low hills). It has been found that the people living in the high hills are the most undernourished, as the lowest percentage of people (52.6 per cent) with an acceptable BMI and the highest percentage of people in the severely malnourished category (11.1 per cent) are found here. People living in urban areas have a better nutritional status. Correlation studies show that the nutritional status of the population improves with age, literacy levels, and small family size. In some cases, calorie and protein intake have a positive impact on the health of the people, whereas size of land holding, number of animals, and income of the family do not have any significant influence on nutritional status. 相似文献
Multichannel auditory brainstem implants (ABI) are currently indicated for patients with neurofibromatosis type II (NF2) involving both vestibulocochlear nerves. The ABI helps bypass the damaged cochlear nerves and restores a level of auditory sensation via the electrical stimulation of the cochlear nucleus. The implant is usually placed in the lateral recess of the fourth ventricle at the time of tumor resection to stimulate the cochlear nucleus. We report a case of ABI done on a 15-year-old girl with bilateral vestibular schwannomas. 相似文献
Several 1-(substituted phenoxy)-3-{[4-(4-trifluoromethyl) phenoxy] piperidin-1-yl} propan-2-ols (str.II) were prepared in
a six-step reaction sequence starting from methylamine and ethyl acrylate and evaluated for antidepressant activity. The compounds
were fully characterized by spectral and elemental analyses, and were tested for their effect on gross behavior, antireserpine
and anorexigenic activity. No effect was observed on gross behavior and some of them showed fluoxetine like antireserpine
and anorexigenic activity. 相似文献
The binding studies of Co(III) and Ru(II) polypyridyl complexes with dsDNA were carried out by molecular modeling studies to identify the binding interactions. The 3D structures of the metal complexes [Ru(phen)2ippip]2+ (RP-ippip), [Co(phen)2ippip]3+ (CP-ippip), [Ru(bpy)2ippip]2+ (RB-ippip), and [Co(bpy)2ippip]3+ (CB-ippip), where ippip = 4-(isopropylbenzaldehyde)imidazo[4,5-f][1,10] phenanthroline, phen = 1,10-phenanthroline, and bpy = bypyridine, were simulated using molecular dynamic simulations for stable conformers. The energy-minimized 3D structures of metal complexes were docked to the double-stranded dodecamer 5′-D(*AP * CP * CP * GP * AP * CP * GP * TP * CP * GP * GP * T)-3′. The aromatic ligand, ippip, facilitates the binding of the metal complex with DNA through intercalation. The effect of ancillary ligands, phen and bpy, was investigated. The ancillary ligands were found to be involved in bond formation with the phosphate backbone of nucleotide base pairs in metal complex–DNA docked complex. The significant interactions of metal complexes in the major groove of DNA are the prerequisite features of the metal complexes to be considered as DNA-intercalator. The molecular docking data are well substantiated by the available experimental data. The modeling results should extend knowledge about the nature of binding of these complexes with DNA. 相似文献
Aim To compare American Diabetes Association and International Expert Committee recommended cut‐off values of HbA1c for detecting the presence of pre‐diabetes against plasma glucose values obtained from oral glucose tolerance tests in Asian Indians. Methods A cross‐sectional randomly sampled population survey involving 2368 adults, aged ≥ 20 years. HbA1c was measured on a Bio‐Rad 10 system in 1972 subjects. Results Of the 1972 subjects studied, 329 were detected to have pre‐diabetes based on isolated impaired fasting glucose in 125 subjects (6.3%), isolated impaired glucose tolerance in 141 subjects (7.1%) and the presence of both in 63 subjects (3.2%). The HbA1c cut‐off of 34 mmol/mol (5.7%), as recommended by the American Diabetes Association for detecting the presence of pre‐diabetes, showed sensitivity of 62%, specificity 77%, with a positive predictive value of 34.7%, a negative predictive value of 89.5% and accuracy of 67.8%; whereas the HbA1c cut‐off recommended by the International Expert Committee of 42 mmol/mol (6%) had a sensitivity of 36%, specificity of 90%, positive predictive value of 42.7%, negative predictive of 85.4% and an accuracy of 77%. However, both these HbA1c cut‐offs underdiagnosed the presence of pre‐diabetes in 38 and 64% of these subjects, respectively. Conclusions The American Diabetes Association and the International Expert Committee recommended HbA1c cut‐off values and oral glucose tolerance tests identify different pre‐diabetes cohorts. Long‐term prospective studies are required to define the usefulness of one over the other. 相似文献
Adaptive optics is a relatively new tool that is available to ophthalmologists for study of cellular level details. In addition to the axial resolution provided by the spectral-domain optical coherence tomography, adaptive optics provides an excellent lateral resolution, enabling visualization of the photoreceptors, blood vessels and details of the optic nerve head. We attempt a mini review of the current role of adaptive optics in retinal imaging. PubMed search was performed with key words Adaptive optics OR Retina OR Retinal imaging. Conference abstracts were searched from the Association for Research in Vision and Ophthalmology (ARVO) and American Academy of Ophthalmology (AAO) meetings. In total, 261 relevant publications and 389 conference abstracts were identified. 相似文献
Epidemiologic findings suggest that lipids and alteration in lipid metabolizing protein/gene may contribute to the development of neurodegenerative disorders. The aim of the current study was to determine the serum lipid levels and genetic variation in two lipid metabolizing genes, low-density lipoprotein receptor-related protein-associated protein (LRPAP1) and apolipoprotein E (APOE) gene in Parkinson’s disease (PD). Based on well-defined inclusion and exclusion criteria, this study included 70 patients with PD and 100 age-matched controls. LRPAP1 and APOE gene polymorphism were analyzed by polymerase chain reaction and restriction fragment length polymorphism, respectively. Fasting serum lipid levels were determined using an autoanalyser. The logistic regression analysis showed that high levels of serum cholesterol [odds ratio (OR) = 1.101, 95 % confidence interval (CI95%) = 1.067–1.135], LRPAP1 I allelic variant alone (OR = 2.766, CI95% = 1.137–6.752) and in combination with APOE ε4 allelic variant (OR = 4.187, CI95% = 1.621–10.82) were significantly associated with increase in PD risk. Apart from that, the high levels of LDL cholesterol appears to have a protective role (OR = 0.931, CI95% = 0.897–0.966) against PD. The LRPAP1 I allelic variant may be considered a candidate gene for PD, predominantly in patients having the APOE ε4 allelic variant. 相似文献
