Conformation of a Protein Kinase C Substrate, NG(28-43), and Its Analog in Aqueous and Sodium Dodecyl Sulfate Micell Solutions
A peptide corresponding to the neuronal protein neurogranin (NG) residues 28-43, NG(28-43), and its analog, [A(35)]NG(28-43), have been investigated by NMR, electron paramagnetic resonance (EPR), and circular dichroism (CD) spectroscopies. The peptides existed in aqueous solution predominantly in…

Effects of quercetin on insulin-like growth factors (IGFs) and their binding protein-3 (IGFBP-3) secretion and induction of apoptosis in human prostate cancer cells
BACKGROUND: Quercetin, the predominant flavonoid, has been reported to lower the risk of several cancers. This flavonoid found in onion, grapes, green vegetables, etc. has been shown to possess potent antiproliferative effects against various malignant cells. This study was designed to investigate…

Use of Nutrition Risk in Critically ill (NUTRIC) Score to Assess Nutritional Risk in Mechanically Ventilated Patients: A Prospective Observational Study
CONTEXT: Nutritional risk assessment must be done on all critically ill patients. Malnutrition in intensive care unit (ICU) patients is associated with adverse clinical outcomes. Traditional scoring systems cannot be used for screening in mechanically ventilated (MV) patients because these patients…

Quercetin-induced growth inhibition and cell death in prostatic carcinoma cells (PC-3) are associated with increase in p21 and hypophosphorylated retinoblastoma proteins expression
Prostate cancer is the major health problem and the leading cause of male cancer death. Quercetin is a novel antitumor and antioxidant, whose molecular mechanism involved in cell cycle arrest in androgen independent prostate cancer cells remains unclear. In this study, we investigated the effects…

The surface reactivity of silver nanoparticles doped with TiO2 nanorod like crystals for enhancing photocatalytic degradation of harmful water pollutants under visible - light irradiations
A novel and highly efficient photocatalytic system was successfully engineered through the initial synthesis of TiO₂ nanoparticles, followed by their morphological transformation into one-dimensional TiO₂ nanorod-like crystals (TiO₂ NRCs) via a hydrothermal strategy. To further tailor the surface…

Effect of fins in enhancing phase change material fusion in a spherical thermal energy storage container
The increased depletion of fossil fuels needs alternatives like solar energy to address daily demands. However, solar energy is intermittent, hence it is integrated with thermal energy storage (TES) systems. Phase change materials (PCM) are used in TES systems, but they suffer from meagre thermal…
