Drug Repositioning for Scorpion Envenomation Treatment Through Dual Inhibition of Chlorotoxin and Leiurotoxin.

Scorpion envenomation, a grave public health concern, is primarily driven by the potent neurotoxins chlorotoxin and leiurotoxin present in Leiurus species venom. Developing effective treatments is crucial to mitigate its impact. Utilizing a drug-repositioning bioinformatics-based approach, potential inhibitors of these neurotoxins were identified from Food and Drug Administration (FDA)-approved drugs.

Overcoming Resistance in Cancer Therapy: Computational Exploration of PIK3CA Mutations, Unveiling Novel Non-Toxic Inhibitors, and Molecular Insights Into Targeting PI3Kα.

Phosphoinositide-3-kinases (PI3 K) are pivotal regulators of cell signaling implicated in various cancers. Particularly, mutations in the PIK3CA gene encoding the p110α catalytic subunit drive oncogenic signaling, making it an attractive therapeutic target. Our study conducted in silico exploration of 31 PIK3CA mutations across breast, endometrial, colon, and ovarian cancers, assessing their impacts on response to PI3Kα inhibitors and identifying potential non-toxic inhibitors and also elucidating their effects on protein stability and flexibility.

Unveiling Blastocystis epidemiology in Morocco: subtype diversity among clinical patients with and without gastrointestinal manifestations in the Meknes region.

Blastocystis is an intestinal protist frequently identified in humans and other animals, though its clinical significance remains controversial. This study aimed to determine the prevalence and genetic diversity of Blastocystis in faecal samples from symptomatic (n = 55) and asymptomatic (n = 50) individuals seeking medical care in Meknes, Morocco. Detection of the protist was accomplished through coproparasitological examination and culture in Jones medium.

[Toxicology of synthetic cannabinoids].

Synthetic cannabinoids (CS), or synthetic endocannabinoid receptor agonists, were initially synthesized for basic research into exocannabinoid signaling pathways, as well as in clinical research for their analgesic properties. The use of CS for recreational purposes is a recent phenomenon, but one that has grown very quickly in recent years, since these molecules now represent the main category of new synthetic products (NPS). This literature review aims to bring together current data regarding the use and effects caused by CS in humans.

Prevalence of Blastocystis sp. in Morocco: Comparative assessment of three diagnostic methods and characterization of parasite forms in Jones' culture medium.

It is crucial to detect and distinguish the different forms of Blastocystis to understand better its impact on human health and its epidemiological evolution.

Genetic diversity and evolutionary dynamics of the Omicron variant of SARS-CoV-2 in Morocco.

Among the numerous variants of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) that have been reported worldwide, the emergence of the Omicron variant has drastically changed the landscape of the coronavirus disease (COVID-19) pandemic. Here, we analyzed the genetic diversity of Moroccan SARS-CoV-2 genomes with a focus on Omicron variant after one year of its detection in Morocco in order to understand its genomic dynamics, features and its potential introduction sources. From 937 Omicron genomes, we identified a total of 999 non-unique mutations distributed across 92 Omicron lineages, of which 13 were specific to the country.

Targeted Gene Panel Sequencing Unveiled New Pathogenic Mutations in Patients With Breast Cancer.

The increasing commercialization of new gene panels based on next-generation sequencing for clinical research has significantly improved our understanding of breast cancer genetics and has led to the discovery of new mutation variants. The study included 16 unselected Moroccan breast cancer patients tested with multi-gene panel (HEVA screen panel) using Illumina Miseq, followed by Sanger sequencing to validate the most relevant mutation. Mutational analysis revealed the presence of 13 mutations (11 single-nucleotide polymorphisms [SNPs] and 2 indels), and 6 of 11 identified SNPs were predicted as pathogenic.
