Structural and antimicrobial properties of synthesized gold nanoparticles using biological and chemical approaches.

This study explores the synthesis and characterization of gold nanoparticles (AuNPs) using green and chemical methods, employing ginger extract and curcumin as reducing agents, in comparison to sodium citrate reduction. The biosynthesized AuNPs synthesized with ginger extract exhibited an average hydrodynamic diameter of 15 and 10 nm for curcumin-conjugated AuNPs, while chemically synthesized AuNPs with sodium citrate displayed an average size of 10 nm. Assessments via Zeta potential measurements revealed negative surface charges across all samples, with the curcumin-conjugated AuNPs showing -36.

Patient Safety Domains in Primary Healthcare: A Systematic Review.

Background: Healthcare systems should ensure the provision of quality services to patients without harming them. However, the provision of services is occasionally accompanied by harm or complications, most of which are preventable. Most studies have focused on secondary healthcare rather than primary healthcare (PHC).

Digenic Inheritance of Mutations in Homologous Recombination Genes in Cancer Patients.

Background/objectives: , , , and are known cancer predisposition genes (CPGs), but tumor risk in patients with simultaneous pathogenic variants (PVs) in CPGs remains largely unknown. In this study, we describe six patients from five families with multiple cancers who coinherited a combination of PVs in these genes.

Methods: PVs were identified using NGS DNA sequencing and were confirmed by Sanger.

New Insights beyond Established Norms: A Scoping Review of Genetic Testing for Infertile Men.

Purpose: From a diagnostic standpoint, certain approaches to genetic screening in clinical practice remain ambiguous in the era of assisted reproduction. Even the most current guidelines do not provide definite guidance on testing protocols, leaving clinicians to carefully determine which tests best serve patients struggling with infertility. The lack of uniformity in the current practice of male fertility evaluation can prove to be quite costly, thus necessitating healthcare practitioners to carefully appraise the necessity and weigh the advantages against potential economic and psychological detriments.

A review of recent developments in the application of nanostructures for sperm cryopreservation.

In the 1970s, sperm cryopreservation was presented as a unique route to fertility preservation. The ability to cryopreserve sperm from all species is challenging. The sperm cryopreservation process encompasses various cellular stresses such as increased osmotic pressure, ice crystal formation, and thermal shock, therefore decreasing the quality of sperm.
