Optical and biological properties of MgO/ZnO nanocomposite derived via eggshell membrane: a bio-waste approach.

A novel synthesis of MgO/ZnO nanocomposite using a template, namely an eggshell membrane (ESM) was attempted. The nanocomposite was characterized by XRD, UV-visible, FTIR, Raman, DLS (zeta potential and particle size distribution), FESEM with EDX, and HRTEM analysis. The presence of periclase cubic MgO (space group Fm3m) and hexagonal wurtzite ZnO (space group P63mc) structures was verified by the XRD results.

AzuR From the SmtB/ArsR Family of Transcriptional Repressors Regulates Metallothionein in sp. Strain PCC 7120.

Metallothioneins (MTs) are cysteine-rich, metal-sequestering cytosolic proteins that play a key role in maintaining metal homeostasis and detoxification. We had previously characterized NmtA, a MT from the heterocystous, nitrogen-fixing cyanobacterium sp. strain PCC 7120 and demonstrated its role in providing protection against cadmium toxicity.

Drug Repurposing for Tooth Regeneration: The Promising Premises.

Drug repurposing which identifies new therapeutic use(s) for drugs currently in use is a brand-new avenue of research interest worldwide. It circumvents the high-end monetary and time investment usually associated with contemporary drug discoveries. In the field of dentistry, recent studies in drug repurposing focuses in attaining dentin repair or reduction of bone resorption associated with apical periodontitis.

Urban stormwater harvesting for domestic water supply: a water evaluation and planning approach.

Renewable groundwater and surface water supplies are insufficient for the current worldwide urban population as water demand is increasing rapidly. Usage per capita in urban areas transcends 160 liters per day. Climate change is projected to increase water demand even more.

Influence of Pyrexia on Pharmacokinetics of Azithromycin and Its Interaction With Tolfenamic Acid in Goats.

Azithromycin is a macrolide antimicrobial agent of the azalide group with a broad spectrum of activity against gram-negative and gram-positive bacterial organisms. Tolfenamic acid is a non-steroidal anti-inflammatory drug of the fenamate group, which is used extensively in humans and animals due to its anti-inflammatory, analgesic, and antipyretic properties. There is dearth of literature on any type of drug interaction between azithromycin and tolfenamic acid in any species, including human beings and alteration of its pharmacokinetics by fever.
