Species composition and diversity of tree species along an altitudinal gradient in Sewa catchment of north-western Himalayas, Jammu and Kashmir, India

Species diversity along altitudinal and latitudinal gradient differs in different tree layers at different scales. Thirteen community groups characterized by different dominants in the tree layer were encountered within an altitudinal range of 580 m asl to 3500 m asl and above in Sewa catchment of Bani region, district Kathua, Jammu and Kashmir. The sub-tropical and temperate elements of vegetation reveal predominance of closed canopy forests, wherein the sub-tropical tree species outnumber the temperate tree flora. The pattern of plant diversity as observed by the values of species richness and diversity indices show a decreasing trend from lower to higher altitudes. The study suggests that distribution and species richness are largely regulated by physiography (altitude, latitude, slope, aspect etc.) and climatic factors.

Global Gene Expression Profiles of Subcutaneous Adipose and Muscle from Glucose-Tolerant, Insulin-Sensitive, and Insulin-Resistant Individuals Matched for BMI

OBJECTIVE - To determine altered gene expression profiles in subcutaneous adipose and skeletal muscle from nondiabetic, insulin-resistant individuals compared with insulin-sensitive individuals matched for BMI. RESEARCH DESIGN AND METHODS - A total of 62 nondiabetic individuals were chosen for extremes of insulin sensitivity (31 insulin-resistant and 31 insulin-sensitive subjects; 40 were European American and 22 were African American) and matched for age and obesity measures. Global gene expression profiles were determined and compared between ethnic groups and between insulin-resistant and insulin-sensitive participants individually and using gene-set enrichment analysis. RESULTS - African American and European American subjects differed in 58 muscle and 140 adipose genes, including many inflammatory and metabolically important genes. Peroxisome proliferator-activated receptor γ cofactor 1A (PPARGC1A) was 1.75-fold reduced with insulin resistance in muscle, and fatty acid and lipid metabolism and oxidoreductase activity also were down-regulated. Unexpected categories included ubiquitination, citrullination, and protein degradation. In adipose, highly represented categories included lipid and fatty acid metabolism, insulin action, and cell-cycle regulation. Inflammatory genes were increased in European American subjects and were among the top Kyoto Encyclopedia of Genes and Genomes pathways on gene-set enrichment analysis. FADS1, VEGFA, PTPN3, KLF15, PER3, STEAP4, and AGTR1 were among genes expressed differentially in both adipose and muscle. CONCLUSIONS - Adipose tissue gene expression showed more differences between insulin-resistant versus insulin-sensitive groups than the expression of genes in muscle. We confirm the role of PPARGC1A in muscle and show some support for inflammation in adipose from European American subjects but find prominent roles for lipid metabolism in insulin sensitivity independent of obesity in both tissues.

Psychosocial and quality of life assessment in cancer patients: a pilot study in Indian set up

Background: Routine screening for distress is internationally recommended as a standard of care among cancer patients. This study was conducted to assess the level of stress and determine the association between quality of life (QOL) with demographic, socio-economic status, treatment phase, cancer stage, etc.Methods: An observational study, performed in the department of Clinical Oncology, Nayati Multi Super Speciality Hospital, Mathura, India. Data of 62 histopathologically proven cancer patients between Nov 2016 and July 2018, were analyzed. This pilot study was conducted to assess the QOL and stress levels of cancer patients by using scales of WHOQOL-BREF, QSC-R23 and Hamilton scale. Results: Among 62 cancer patients, high distress along with poor QOL was seen maximum in males, 40-60 year age group and educated. In majority of domains, high distress was found in middle class, whereas poor QOL was found in Lower class in Environmental domain (p<0.01). We found higher distress in nuclear families (p<0.05). High distress was seen in cancer patients who were aware of illness and was found to statistically significant. Poor QOL in stage 4 was found to be statistically significant in Psychological domain of WHOQOL-BREF. High distress was found in patients undergoing treatment in all patients as compared to Pre-treatment phase and Post-treatment phase (p<0.05).Conclusion: To assess psychological stress in cancer patients using all three scales we could not obtain a conclusive result covering all dimensions of QOL. So, in our next study authors plan to develop one indigenous new scale

Study of Photoluminescence Behaviour of Porous Silicon Samples Prepared at 20 mA Current Density

The paper presents a study on a series of porous silicon films of various thicknesses, prepared at 20 mA current density using a photoluminescence fitting model to determine the average crystallite size of sphe-rical shaped interconnected silicon quantum dots. Discrepancy in photoluminescence behavior of the samples is well explained with this model. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/3097

Combined effect of boron and salt on polypeptide resolutions in wheat (Triticum aestivum) varieties differing in their tolerance

Salinity aggravates toxicity symptoms of boron in wheat. Four wheat (Triticum aestivum L.) varieties differing in tolerance to these stresses were subjected to five stress treatments [control (2.5 ppm B), 50 ppm B + 6 dS/m, 100 ppm B + 6 dS/m, 50 ppm B + 10 dS/m and 100 ppm B + 10 dS/m]. Higher reductions for root length, fresh and dry weight were observed in Schomburgk and HD 2009 varieties at 100 ppm B + 10 dS/m NaCl in comparison to KRL 35 and BTSchomburgk. Results indicated that combined boron and salt stresses significantly increased soluble B and proline concentrations in the roots. At the highest level of stress (100 ppm B + 10 dS/m), maximum proline accumulation was evident in HD 2009 (18.6 mg/g) and minimum in KRL 35 (13.5 mg/g). Protein profile expressions of boron tolerant and intolerant varieties of wheat showed de novo synthesis of two specific polypeptides (35.73 and 31.10 KDa) in boron tolerant variety and one (16.98 kDa) in boron intolerant variety. Likewise, KRL 35 (salt tolerant) showed 4 specific polypeptides of 89.13, 58.4, 46.21 and 31.10 kDa, whereas three specific polypeptides (24.05, 19.13 and 17.52 kDa) appeared in the salt intolerant variety (HD 2009). Appearance of 5 common polypeptides bands of MW 89.13, 53.4, 46.21. 31.10 and 25.12 kDa in both the tolerant varieties, i.e. BT-Schomburgk (boron tolerant) and KRL 35 (salt tolerant) is of special interest and could have possible use as markers for tolerance. The synthesis of common polypeptide of MW 25.12 kDa was observed in all the four varieties with increase in stress treatments

Withaferin A inhibits lysosomal activity to block autophagic flux and induces apoptosis via energetic impairment in breast cancer cells

Withaferin A (WFA), a steroidal lactone, negatively regulates breast cancer growth however, its mechanisms of action remain largely elusive. We found that WFA blocks autophagy flux and lysosomal proteolytic activity in breast cancer cells. WFA increases accumulation of autophagosomes, LC3B-II-conversion, expression of autophagy-related proteins and autophagosome/lysosome fusion. Autolysosomes display the characteristics of acidic compartments in WFA-treated cells; however, the protein degradation activity of lysosomes is inhibited. Blockade of autophagic flux reduces the recycling of cellular fuels leading to insufficient substrates for tricarboxylic acid (TCA) cycle and impaired oxidative phosphorylation. WFA decreases expression and phosphorylation of LDHA, the key enzyme that catalyzes pyruvate-to-lactate conversion, reduces ATP levels and increases AMPK activation. AMPK-inhibition abrogates while AMPK-activation potentiates WFA's effect. WFA and 2-deoxyglucose combination elicits synergistic inhibition of breast cancer cells. Genetic-knockout of BECN1 and ATG7 fails to rescue cells from WFA-treatment; in contrast, addition of methyl pyruvate to supplement TCA cycle protects WFA-treated cells. Together, these results implicate that WFA is a potent lysosomal inhibitor; energetic impairment is required for WFA-induced apoptosis and growth-inhibition and combining WFA and 2DG is a promising therapeutic strategy for breast cancer
