The impact of therapy on the quality of life in asymptomatic patients with freshly detected hypertension

Background: Hypertension is an commonly encountered disease which adversely affect  all aspects of quality of life (QoL). The existing studies are confounded by the presence of multiple comorbidities and inclusion of elderly, which by themselves impairs the QoL. There is thus a need to study the impact of hypertension on QoL, in isolation.Method: This is a single center, prospective, intention to treat, observation study. The aim of the study is to evaluate the change in the QoL over six months, in newly diagnosed asymptomatic patients of hypertension. The tools used to assess the QoL included World Health Organisation’s Quality of Life Questionnaire (WHOQOL- BREF) and Short Form-36 (SF-36).Result: A total of 232 patients (172 males and 60 females) were enrolled in the study. The mean age was 44.66 years. A total of 102 patients (43.97%) had stage-1 and 130 patients (56.03%) had stage-2 hypertension. The female gender is associated with a higher likelihood of presentation with stage-2 hypertension. The male cohort had a better baseline QoL. The desired blood pressures was achieved in 40.52%. With therapy, the QoL improved significantly; sub-hoc analysis showed, the improvement was higher in males and those with stage-1 hypertension. There is an inverse relationship between the QoL and requirement for higher number of antihypertensive mediations.Conclusions: In patients with asymptomatic primary hypertension, treatment improves all aspects of QoL. The factors adversely affecting the QoL include female gender, higher stage of hypertension, poor blood pressure control and requirement of higher numbers of antihypertensive medicine

Synthesis, Spectroscopic, and Antimicrobial Studies of Binuclear Metallocene (M = Ti, Zr, or Hf) Derivatives of Bis(mercaptoazoles)

The reactions of (η5 − C5H5)2MCl2 (M = Ti, Zr, or Hf) with mercaptoazoles (LH2), namely, bis(mercaptotriazoles), bis(mercap- tooxadiazoles), and bis(mercaptothiadiazoles) in 2 : 1 molar ratio, respectively, have been studied in dry tetrahydrofuran in the presence of n-butylamine and the binuclear complexes of the type [{(η − C5H5)2 M}2(L)] (M = Ti/Zr/Hf) are obtained. Tentative structural conclusions are drawn for the reaction products based upon elemental analysis, electrical conductance, magnetic moment, and spectral data (UV-Vis, IR, 1H NMR, and 13C NMR). FAB-mass spectra of few complexes of each series were also carried out to confirm the binuclear structures. Studies were conducted to assess the growth-inhibiting potential of the complexes synthesized, and the ligands against various fungal and bacterial strains

A study was conducted to explore the woody species diversity of Kamla Nehru Institute of Physical & Social Sciences (KNIPSS) main campus spreading over approx. 45 acre of land area. Data was derived from extensive field survey. Identification of the woody species was done using local floras and various external resources. A total of 43 woody species belonging to 24 families is represented in study area. The 39 species were represented as angiosperm and 04 species as represented as gymnosperm respectably. Result showed that 17 families consists of only 1 species each, 2 families have 2 species each respectively. Of the total species, available in campus 30 are native and 13 are exotic.  The Apocynaceae, Caesalpiniaceae and Moraceae were the dominant families of the woody species on the KNIPSS main campus

Differentially localized survivin and STAT3 as markers of gastric cancer progression: Association with Helicobacter pylori

BackgroundLocalization and differential expression of STAT3 and survivin in cancer cells are often related to distinct cellular functions. The involvement of survivin and STAT3 in gastric cancer has been reported in separate studies but without clear understanding of their kinetics in cancer progression.MethodsWe examined intracellular distribution of STAT3 and survivin in gastric adenocarcinoma and compared it with normal and precancer tissues using immunoblotting and immunohistochemistry.ResultsAnalysis of a total of 156 gastric samples comprising 61 histologically normal, 30 precancerous tissues (comprising intestinal metaplasia and dysplasia), and 65 adenocarcinomas, collected as endoscopic biopsies from treatment naïve study participants, revealed a significant (P < .001) increase in overall protein levels. Survivin expression was detectable in both cytoplasmic (90.8%) and nuclear (87.7%) compartments in gastric adenocarcinomas lesions. Precancerous dysplastic gastric lesions exhibited a moderate survivin expression (56.7%) localized in cytoplasmic compartment. Similarly, STAT3 and pSTAT3 expression was detected at high level in gastric cancer lesions. The levels of compartmentalized expression of survivin and STAT3/pSTAT3 correlated in precancerous and adenocarcinoma lesions. Although overexpression of these proteins was found associated with the tobacco use and alcohol consumption, their expression invariably and strongly correlated with concurrent Helicobacter pylori infection. Receiver operating characteristic analysis of nuclear survivin, STAT3, and pSTAT3 in different study groups showed acceptable positive and negative predictive values with area under the curve above 0.8 (P < .001).ConclusionOverall, our results suggest that overall increase in survivin and STAT3 and their subcellular localization are key determinants of gastric cancer progression, which can be collectively used as potential disease biomarkers and therapeutic targets for gastric cancer.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/1/cnr21004-Supplementary_Methods_20180313.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/2/cnr21004-sup-0001-F1.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/3/cnr21004_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/144680/4/cnr21004.pd

Drought and salinity stresses induced physio-biochemical changes in sugarcane: an overview of tolerance mechanism and mitigating approaches

Sugarcane productivity is being hampered globally under changing environmental scenarios like drought and salinity. The highly complex nature of the plant responses against these stresses is determined by a variety of factors such as genotype, developmental phase of the plant, progression rate and stress, intensity, and duration. These factors influence plant responses and can determine whether mitigation approaches associated with acclimation are implemented. In this review, we attempt to summarize the effects of drought and salinity on sugarcane growth, specifically on the plant’s responses at various levels, viz., physiological, biochemical, and metabolic responses, to these stresses. Furthermore, mitigation strategies for dealing with these stresses have been discussed. Despite sugarcane’s complex genomes, conventional breeding approaches can be utilized in conjunction with molecular breeding and omics technologies to develop drought- and salinity-tolerant cultivars. The significant role of plant growth-promoting bacteria in sustaining sugarcane productivity under drought and salinity cannot be overlooked

Anti-thrombotic efficacy of S007-867: Pre-clinical evaluation in experimental models of thrombosis in vivo and in vitro.

Pharmacological inhibition of platelet collagen interaction is a promising therapeutic strategy to treat intra-vascular thrombosis. S007-867 is a novel synthetic inhibitor of collagen-induced platelet aggregation. It has shown better antithrombotic protection than aspirin and clopidogrel with minimal bleeding tendency in mice. The present study is aimed to systematically investigate the antithrombotic efficacy of S007-867 in comparison to aspirin and clopidogrel in vivo and to delineate its mechanism of action in vitro. Aspirin, clopidogrel, and S007-867 significantly reduced thrombus weight in arterio-venous (AV) shunt model in rats. In mice, following ferric chloride induced thrombosis in either carotid or mesenteric artery; S007-867 significantly prolonged the vessel occlusion time (1.2-fold) and maintained a sustained blood flow velocity for >30 min. Comparatively, clopidogrel showed significant prolongation in TTO (1.3-fold) while aspirin remained ineffective. Both S007-867 and aspirin did not alter bleeding time in either kidney or spleen injury models, and thus maintained hemostasis, while clopidogrel showed significant increase in spleen bleeding time (1.7-fold). The coagulation parameters namely thrombin time, prothrombin time or activated partial thromboplastin time remained unaffected even at high concentration of S007-867 (300 µM), thus implying its antithrombotic effect to be primarily platelet mediated. S007-867 significantly inhibited collagen-mediated platelet adhesion and aggregation in mice ex-vivo. Moreover, when blood was perfused over a highly thrombogenic combination of collagen mimicking peptides like CRP-GFOGER-VWF-III, S007-867 significantly reduced total thrombus volume or ZV50 (53.4 ± 5.7%). Mechanistically, S007-867 (10-300 μM) inhibited collagen-induced ATP release, thromboxane A2 (TxA2) generation, intra-platelet [Ca+2] flux and global tyrosine phosphorylation including PLCγ2. Collectively the present study highlights that S007-867 is a novel synthetic inhibitor of collagen induced platelet activation, that effectively maintains blood flow velocity and delays vascular occlusion. It inhibits thrombogenesis without compromising hemostasis. Therefore, S007-867 may be further developed for the treatment of thrombotic disorders in clinical settings
