Advances in the Optimization of Fe Nanoparticles: Unlocking Antifungal Properties for Biomedical Applications.

In recent years, nanotechnology has achieved a remarkable status in shaping the future of biological applications, especially in combating fungal diseases. Owing to excellence in nanotechnology, iron nanoparticles (Fe NPs) have gained enormous attention in recent years. In this review, we have provided a comprehensive overview of Fe NPs covering key synthesis approaches and underlying working principles, the factors that influence their properties, essential characterization techniques, and the optimization of their antifungal potential.

Identification of a novel candidate HSD3B2 gene variant for familial hypospadias by whole-exome sequencing.

Hypospadias [MIM: 300633] is one of the most frequent congenital malformations of male external genitalia. The spectrum of genetic variants causing hypospadias is varied, with studies commonly implicating genes critical in the fetal steroidogenic pathway. This is the first genetic study on hypospadias from the Yemen ethnicity and the second to report mutations in more than one affected individual from the same family.

Clinical characterization and further confirmation of the autosomal recessive SLC12A2 disease.

Heterozygous pathogenic variants in SLC12A2 are reported in patients with nonsyndromic hearing loss. Recently, homozygous loss-of-function variants have been reported in two patients with syndromic intellectual disability, with or without hearing loss. However, the clinical and molecular spectrum of SLC12A2 disease has yet to be characterized and confirmed.

Negatively charged food additive dye "Allura Red" rapidly induces SDS-soluble amyloid fibril in beta-lactoglobulin protein.

Recent studies have led to an increased interest to categorize small molecular inhibitors of protein fibrillation. In this study, we used spectroscopy, microscopy and gel electrophoresis techniques that provides an elaborated description of the Allura Red-induced amyloid fibrillation in the β-LG protein at two pHs (7.4 and 3.

Mitochondrial DNA variations in ova and blastocyst: implications in assisted reproduction.

Mitochondrial DNA (mtDNA) of oocyte is critical for its function, embryo quality and development. Analysis of complete mtDNA of 49 oocytes and 18 blastocysts from 67 females opting for IVF revealed 437 nucleotide variations. 40.

Herbo-mineral supplementation in men with idiopathic oligoasthenoteratospermia : A double blind randomized placebo-controlled trial.

Introduction: There is insufficient scientific data on the medical management options for idiopathic oligoasthenoteratospermia (iOATs). We conducted a double blind, randomized, placebo-controlled trial to assess the efficacy and safety of the herbo-mineral supplement, Addyzoa(®), in infertile men with iOATs. We also evaluated its effect on semen reactive oxygen species (ROS) levels, total antioxidant capacity (TAC) and DNA fragmentation index.

Idiopathic recurrent pregnancy loss: role of paternal factors; a pilot study.

Background: This case-control study was designed with the aim of evaluating the role of sperm, oxidative stress and DNA damage in idiopathic recurrent pregnancy loss (iRPL). This pilot study is the first study done on the Indian population which reports the association between DFI, TAC and ROS in couples experiencing iRSA.

Methods: Twenty infertile men with a history of iRPL and 20 fertile controls (having fathered a child a year earlier) were included in the study which was performed in Laboratory for Molecular Reproduction and Genetics, India, from March 2010 to July 2011.

Clinical significance of sperm DNA damage threshold value in the assessment of male infertility.

Sperm DNA integrity is a prerequisite for normal spermatozoal function. The aim of the study was to evaluate the role of sperm chromatin damage, its cut-off level and its effect on sperm parameters in men with idiopathic infertility by analyzing 100 idiopathic infertile men and 50 fertile controls. Semen samples were analyzed as per WHO 1999 guidelines and sperm chromatin structure assay (SCSA) was applied to measure DNA fragmentation index (DFI) in sperm.

Sperm DNA integrity assays: diagnostic and prognostic challenges and implications in management of infertility.

Sperm is not a simple carrier of paternal genetic information but its role extends clearly beyond fertilization. Integrity of sperm genome is an essential pre-requisite for birth of healthy offspring and evaluation of sperm should entail DNA integrity analysis. DNA integrity analysis is a better diagnostic and prognostic marker of sperm reproductive potential.

Attenuation of oxidative stress & DNA damage in varicocelectomy: implications in infertility management.

Sperm DNA integrity is of vital importance for foetal development and birth of healthy offspring. Oxidative stress and consequent DNA damage are the major cause of decline in semen quality in men with varicocele. A preliminary study was conducted on 11 men with clinical varicocele who also had high levels of reactive oxygen species (ROS), to assess DNA damage in sperms and ROS levels before and after varicocelectomy.

Mitochondrial DNA Mutations in etiopathogenesis of male infertility.

Objective: To understand role of mitochondrial (mt) mutations in genes regulating oxidative phosphorylation (OXPHOS) in pathogenesis of male infertility. Infertility affects approximately 15% of couples trying to conceive. Infertility is frequently attributed to defects of sperm motility and number.
