Cryoprotective effect of zinc and gold nanoparticles during cooling and freeze-thawing on Marwari stallion sperm parameters and reactive oxygen species production.

Background: Sperm cryopreservation is one of the most important procedures in the development of biotechnologies for assisted reproduction. Cryopreservation of stallion spermatozoa tends to cause plasma membrane damage due to the low ratio of cholesterol to phospholipids. Different substances and compounds can be added to semen extenders to improve sperm quality.

Impact of Transportation on the Suitability of Cryopreserved Corneal Lenticule for Implantation.

Corneal lenticules can be deposited and retrieved for vision-restoring surgeries. Extended transportation logistical delays from the lenticule bank to the clinic could be a concern. To investigate this, corneal lenticules were cryopreserved at a Ministry of Health of Singapore-licensed lenticule bank for 1 year and were then transported at 4 °C.

EXPRESS: Metformin; Its Salutary Effects Beyond Diabetes Mellitus.

Metformin, an oral hypoglycemic agent, is commonly used in patients with type II diabetes mellitus. Studies have shown its use is associated with reduction in major cardiovascular events (MACE) in patients with type 2 diabetes such as hospitalization for acute myocardial infarction, stroke, transient ischemic attack, or cardiovascular death. [1-6] There is also a suggestion that metformin may have effects beyond those relating to lowering of blood sugar.

Recent advancements on 2D nanomaterials as emerging paradigm for the adsorptive removal of microcontaminants.

Water reservoirs are facing increasing prevalence of microcontaminants originating from agricultural runoff, industrial effluents, and domestic wastewater. The persistence of microcontaminants leads to disruptions in aquatic ecosystems and poses potential long-term health risks to humans, even at minimal concentrations. However, traditional wastewater treatment methods are inefficient to eliminate the microcontaminants because of their intricate chemical structures and low concentration.
