A novel analogue of hybrid spirooxindoles was synthesized employing a systematic multistep synthetic approach. The synthetic protocol was designed to obtain a series of spirooxindole derivatives incorporating triazolyl--triazine framework via [3 + 2] cycloaddition (32CA) reaction of azomethine ylide ( with the corresponding chalcones . Unexpectedly, the reaction underwent an alternate route, leading to the cleavage of the s-triazine moiety and yielding a series of spirooxindole derivatives incorporating a triazole motif.

In this work, new hydroxyl functionalized imidazolium ionic liquids were prepared from condensation of ethanolamine with glyoxal and formalin in the presence of acetic acid as catalyst. The chemical modification of the hydroxyl groups with epichlorohydrine added new hydroxylpropanoxychloride groups on the imidazolium cation that were quaternized with -methylimidazolium chloride to produce new imidazolium acetate ionic liquids.

Arsenic (As) contaminated groundwater is a worldwide concern due to its chronic effects on human health. The objectives of the study were to evaluate natural inexpensive raw laterite (RL) and kaolinite (RK) for their potential use as As sorbents and to understand the As sorption on laterite and kaolinite by employing sorption and kinetic models. Raw laterite and RK were tested for EC, pH, XRF and CEC as basic parameters.

In lab and hydroponic experiments, osmotic stress levels (control, -2, -4, -6 and -8 Bars) created by PEG-6000, caused a significant decline in germination, mean germination time, root, shoot, and coleoptile length in both wheat genotypes examined. Germination was inhibited more in Wafaq-2001 than in Chakwal-50.
View Article and Find Full Text PDFAims: Crosstalk between cardiomyocytes and fibroblasts in physiological conditions and during disease remains poorly defined. Previous studies have shown that fibroblasts and myocytes interact via paracrine communication, but several experimental confounding factors, including the use of immature myocytes and the induction of alpha-smooth muscle actin (α-SMA) expression in fibroblasts by prolonged culture, have hindered our understanding of this phenomenon. We hypothesize that fibroblasts and myofibroblasts differentially affect cardiomyocytes viability, volume, and Ca(2+) handling via soluble mediators.

The aim of this study was to establish and characterise adult human myocardial slices from small patients' heart biopsies as a simple, reproducible and relevant preparation suitable for the study of human cardiac tissue at the multicellular level. Vibratome-cut myocardial slices were prepared from left ventricular biopsies obtained from end-stage heart failure patients undergoing heart transplant or ventricular assist device implantation, and from hearts of normal dogs.
