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.

Chitosan-Zinc-Ligated Hydroxychloroquine: Molecular Docking, Synthesis, Characterization, and Trypanocidal Activity against .

The existing treatments against are faced with several drawbacks, such as limited drug options, resistance, the relapse of infection, toxicity, etc., which emphasizes the necessity for new alternatives. We synthesized novel metal-based antiparasitic compounds using chitosan, hydroxychloroquine (HC), and ZnO nanoparticles (NPs) and characterized them for size, morphology, chemical interactions, etc.

Antiviral and Cytoprotective Effect of Zinc (Yasad Bhasma) Based Nanoformulations Against Bovine Coronavirus.

Ayurvedic medicine utilizes metal-based preparations, known as bhasmas, to treat various health conditions. Yasad bhasma (YB), a zinc-based ayurvedic preparation, shows promise as a potential candidate for developing zinc-based nanomedicines with anti-inflammatory and antioxidant properties. In this study, we synthesized a formulation combining YB and hydroxychloroquine (HC) as a zinc ionophore (YBHC) and investigated its biocompatibility and antiviral effects against buffalo calf coronavirus (BCoV) in Vero cells.

A biologically functional bioink based on extracellular matrix derived collagen for 3D printing of skin.

Over the past few years, several advancements have been made to develop artificial skin that mimics human skin. Artificial skin manufactured using 3D printing technology that includes all epidermal and dermal components, such as collagen, may offer a viable solution. The skin-specific bioink was derived from digested chicken skin and incorporated into PVA (polyvinyl alcohol) and gelatin.
