The genetic origin of the Kalash, an isolated community in northern Pakistan, have long been a subject of debate. This study aimed at investigating the genetic diversity and ancestral composition of Kalash people using an advanced set of genetic data including 22 autosomal and 23 Y chromosomal STRs. We elucidated their historical movements and potential connections to ancient populations by investigating their distinct alleles and comparing them with other regional and global populations to catalog their phylogenetic associations.

Aim: The aim of this review was to evaluate the safety profile of gadoterate meglumine from published literature and pharmacovigilance reports of adverse drug reactions (ADRs) encompassing 35 years of clinical use and more than 170 million administered doses.

Materials And Methods: A review of published literature up to December 31, 2024 was performed through a search in Embase and PubMed databases. The analysis focused on current safety concerns associated with gadolinium-based contrast agents, the hypersensitivity reactions (HSRs), nephrogenic systemic fibrosis (NSF), gadolinium accumulation, and symptoms associated with gadolinium exposure.

Objective: Some patients who received multiple administrations of gadolinium-based contrast agents (GBCAs) have been reported to develop "symptoms associated with gadolinium exposure" (SAGE). The aim of this study was to analyze pharmacovigilance data and to explore the various SAGE patterns of linear and macrocyclic GBCAs among patients exhibiting 3 or more SAGE symptoms.

Materials And Methods: SAGE were identified from a review of the scientific literature, and the corresponding preferred terms (PTs) were searched in each system organ class recorded in the FDA Adverse Event Reporting System (FAERS).

Article Synopsis
  • Dengue virus, transmitted primarily by Aedes mosquitoes, poses a major health risk in tropical areas and consists of four serotypes, with DENV-2 identified as the most prevalent in recent studies from Pakistan (2023-2024).
  • Research involved analyzing serum samples to identify serotypes and characterized the envelope gene using techniques like nested PCR and sequencing, revealing DENV-2's close relation to strains in China and India.
  • The study suggests potential antiviral compounds, specifically Arbidol and Quercetin, and identifies B-cell epitopes for future vaccine development, aiming to improve dengue management strategies in the region.

Dengue virus (DENV) infection is a worldwide public health concern infecting approximately 400 million individuals and about 40,000 mortalities yearly. Despite this, no licensed or readily available antiviral medication is currently available specifically for DENV infection, and therapy is typically symptomatic. Therefore, the objective of the study was to investigate the antiviral activity of Beta vulgaris L.

The carbon footprint (CFP) is a measure of greenhouse gases (GHGs) emitted throughout the lifecycle of a product or activity, while the energy footprint (EFP) and water footprint (WFP) measure energy and water consumption, respectively. These footprints are essential for managing emissions and consumption and promoting low-carbon consumption. A carbon labeling scheme could help consumers make informed choices.

This study investigated pH-responsive Terbinafine HCL (TBH)-loaded nanogels as a new approach to treating superficial fungal infections. Acrylic acid (AA) is a synthetic monomer that was crosslinked with a natural polymer (gelatin) using a free radical polymerization technique to fabricate gelatin-g-poly-(acrylic acid) nanogels. Ammonium persulphate (APS) and N, N'-methylene bisacrylamide (MBA) were used as the initiator and crosslinker, respectively.

Ecosystem degradation and fossil fuel depletion are the two foremost concerns to look for alternative fuels. Rapid population growth is primarily accountable for higher consumption of fossil fuel sources, although engine technology is achieving milestones in terms of fuel efficiency and lower exhaust emissions in order to contribute towards a sustainable environment. The main root cause of global warming is carbon dioxide emissions; therefore, it is imperative to assess the impact of alternative fuels in diesel engines with an aim to minimize carbon emissions.

Key Clinical Message: Respiratory viruses, particularly COVID-19, can be associated with severe cases of myocardial infarction (MI). Physicians should have a low threshold for MI in COVID-19 patients who present with persistent chest pain as MI in rapidly deteriorating cases can be missed.

COVID-19-infected individuals and those who recovered from the infection have been demonstrated to have elevated liver enzymes or abnormal liver biochemistries, particularly with preexisting liver diseases, liver metabolic disorders, viral hepatitis, and other hepatic comorbidities. However, possible crosstalk and intricate interplay between COVID-19 and liver disease severity are still elusive, and the available data are murky and confined. Similarly, the syndemic of other blood-borne infectious diseases, chemical-induced liver injuries, and chronic hepatic diseases continued to take lives while showing signs of worsening due to the COVID-19 crisis.
