Breast cancer (BC) in Oman affects younger women and has a more aggressive course. Clinical and biological variables like age, pregnancy, tumor size, type, grade, receptor expression and proliferation predict disease aggression but there is no direct predictor of metastasis except lymphovascular invasion. Epithelial-mesenchymal transition (EMT) is characterized by epithelial cells losing epithelial and acquiring mesenchymal morpho-immunophenotypic characteristics. In tumors, EMT-like transitions may signify a metastatic phenotype and have features in common with cancer stem cells (CSC) which show resistance to chemotherapy...

Selection of suitable Municipal Solid Waste Management (MSWM) options is one of the major challenges in urban areas of the developing countries. Success of MSWM, requires accurate data of generation rate, composition, and physico-chemical characteristics of solid wastes. Improper handling of solid waste can have significant environmental and aesthetical impacts. The present study proposes a new method (applicability index- Pik values) for identifying the most appropriate disposal option with the help of applicability values of Composting-CP, Incineration-IP, and Landfill-LP for individual components of MSW based on the results of the physico-chemical analysis of the collected representative solid waste samples from the study area, Dhanbad, India...

BACKGROUND: Heart failure with preserved ejection fraction (HFpEF) has close ties with hypertension, though risk factors to the development of HFpEF in hypertensive patients are not fully understood. Left ventricular hypertrophy (LVH) signifies the susceptibility toward diastolic heart dysfunction, and genetic determinants of LVH as a result may serve as risk predictors for HFpEF in hypertension. We investigated the role of three renin-angiotensin-aldosterone system (RAAS) gene polymorphisms in the development of LVH in hypertensive patients with a diagnosis of HFpEF...

Signal transducer and activator of transcription 2 (STAT2) is a key element that transduces signals from the cell membrane to the nucleus via the type I interferon-signaling pathway. Although the structural and functional aspects of STAT proteins are well studied in mammals, information on teleostean STATs is very limited. In this study, a STAT paralog, which is highly homologous to the STAT2 members, was identified from a commercially important fish species called rock bream and designated as RbSTAT2. The RbSTAT2 gene was characterized at complementary DNA (cDNA) and genomic sequence levels, and was found to possess structural features common with its mammalian counterparts...

We report the dynamics of compound droplets with a denser liquid (water) droplet over a less dense sessile droplet (mineral oil) that satisfies the Neumann condition. For a fixed size of an oil droplet, depending on the size of the water droplet, either it attains the axisymmetric position or tends to migrate toward the edge of the oil droplet. For a water droplet-to-oil droplet at volume ratio V_w⁄V_o ≥0.05, stable axisymmetric configuration is achieved; for V_w⁄V_o <0.05, migration of water droplet is observed...

The aqueous extract of various plants like C. sativum (AECS), A. tenella colla (AEAT), S. hispida (AESH) and M. verticillata (AEMV) was studied for its hexavalent chromium (Cr(VI)) reduction property. Even though antioxidant activity was present, AEAT, AESH and AEMV did not reduce Cr(VI). AECS showed rapid and dose-dependent Cr(VI) reduction. The efficient reduction of 50 mg/L of Cr(VI) using AECS was attained in the presence of 250 µg/ml of starting plant material, incubating the reaction mixture at pH 2, 30 °C and agitation at 190 rpm...

BACKGROUND: Many parallels exist between growth and development of the placenta and that of cancer. One parallel is shared expression of antigens that may have functional importance and may be recognized by the immune system. Here, we characterize expression and regulation of one such antigen, Trophoblast glycoprotein (TPGB; also called 5T4), in the placenta across gestation, in placentas of preeclamptic (PE) pregnancies, and in purified microvesicles and exosomes. METHODS: Trophoblast glycoprotein expression was analyzed by real-time reverse transcription-polymerase chain reaction (RT-PCR), Western blot, and immunohistochemistry...

This article provides evidence for the long-term affiliation between ecological and cultural changes in German-speaking countries, based on the assumptions derived from social change and human development theory. Based on this theory, the increase in urbanisation, as a measure of ecological change, is associated with significant cultural changes of psychology. Whereas urbanisation is linked to greater individualistic values and materialistic attitudes, rural environments are strongly associated with collectivistic values like allegiance, prevalence of religion, and feelings of belonging and benevolence...
