Green synthesis of Cu-doped ZnO nanoparticles and its application for the photocatalytic degradation of hazardous organic pollutants.

In recent times, the synthesis of metal nanoparticles (NPs) using plant extracts has recently emerged as an intriguing issue in the field of nanoscience and nanobiotechnology, with numerous advantages over conventional physicochemical approaches. In the current study, ZnO NPs were synthesized from Synadium grantii leaf extricate with varying Cu-dopant concentrations. In order to the synthesis of the pure and Cu-doped ZnO NPs, zinc nitrate hexahydrate and copper nitrate trihydrate were used as a precursor in leaf extracts of the plant.

Urinary Versus Recombinant Gonadotropins for Ovarian Stimulation in Women Undergoing Treatment with Assisted Reproductive Technology.

Globally, about 10%-15% couples are affected by infertility, with major role being played by the couple's lifestyle. Several gonadotropin preparations (urinary, purified urinary, recombinant, and biosimilars) are available for use. Purified urinary formulations offer numerous advantages over their predecessor, including lesser injection dose required, ability to be administered subcutaneously, less batch-to-batch variability, better efficacy, ability to individualize protocols as per patient's need, better control of developing follicles, less risk of multiple pregnancies, and hyperstimulation.

Squamous cell carcinoma arising from congenital lymphedema.

Congenital lymphedema is a rare type of primary lymphedema occurring at birth or developing shortly later. Primary lymphedema can be classified according to whether it is familial or sporadic. The primary congenital familial lymphedema is also known as Milroy's disease.

Paediatric nasopharyngeal foreign bodies.

Two unusual cases of foreign bodies, a metallic whistle and a wooden gutty with a threaded screw, lodged in the nasopharyngeal region are reported. The rare feature of absence pf symptoms inspite of impaction for long duration in the paediatric age group is recorded.
