Methods: This was a cross-sectional study of 14 patients (age range 17-40 years), who underwent vaginoplasty at the Aga Khan University Hospital, Karachi, Pakistan between January 2008 to December 2018. We aimed to assess the anatomical outcomes in terms of vaginal depth, axis and functional outcome as painless and satisfactory vaginal intercourse.
Single nucleotide polymorphism is known to alter the expression and processing of miRNAs leading to a variety of diseases including rheumatoid arthritis (RA). However, disagreement is present up to date regarding the association of miRNA-146a and miRNA-499 polymorphisms with RA. The goal of this study was to assess the association of polymorphisms at miRNA-146a and miRNA-499 with the pathogenesis of RA in patients originating from Pakistan.

Alzheimer's disease (AD) is one of the main healthcare challenges of the twenty-first century, not only affecting millions of people's quality of life but also increasing the burden on the medical community, families, and society. It is a neurodegenerative disorder characterized by learning and cognitive dysfunction, behavioral turbulence, and memory loss and is a major cause of dementia, contributing to 50-60 % of dementia cases in patients above the age of 65. The major pathophysiological changes include accumulation of beta-amyloid plaques (Aβ), highly phosphorylated tau protein, neuroinflammation, GABA neurotransmission disruption, mitochondrial dysfunction, neuronal damage due to free radicals, and decreased concentration of acetylcholine (ACh) and butyrylcholine (BCh).

View Article and Find Full Text PDFBackground: Bioconversion of levoglucosan, a promising sugar derived from the pyrolysis of lignocellulose, into biofuels and chemicals can reduce our dependence on fossil-based raw materials. However, this bioconversion process in microbial strains is challenging due to the lack of catalytic enzyme relevant to levoglucosan metabolism, narrow production ranges of the native strains, poor cellular transport rate of levoglucosan, and inhibition of levoglucosan metabolism by other sugars co-existing in the lignocellulose pyrolysate. The heterologous expression of eukaryotic levoglucosan kinase gene in suitable microbial hosts like Escherichia coli could overcome the first two challenges to some extent; however, no research has been dedicated to resolving the last two issues till now.

Among the different methods, the quorum-quenching (QQ) technique is a novel method as it delays biofilm formation on the membrane surface through disruption of bacterial cell-to-cell communication and thus effectively mitigates membrane biofouling. QQ bacteria require a certain concentration of dissolved oxygen to show their best activities.

View Article and Find Full Text PDFPretreatment of lignocellulosic biomass is crucial for the release of biofermentable sugars for biofuels production, which could greatly alleviate the burgeoning environment and energy crisis caused by the massive usage of traditional fossil fuels. Pyrolysis is a cost-saving pretreatment process that can readily decompose biomass into levoglucosan, a promising anhydrosugar; however, many undesired toxic compounds inhibitory to downstream microbial fermentation are also generated during the pyrolysis, immensely impeding the bioconversion of levoglucosan-containing pyrolysate. Here, we took the first insight into the proteomic responses of a levoglucosan-utilizing and ethanol-producing to three representative biomass-derived inhibitors, identifying large amounts of differentially expressed proteins (DEPs) that could guide the downstream metabolic engineering for the development of inhibitor-resistant strains.
