Commiphora africana (A Rich) Engel., known as ‘African myrrh’, is a medicinal plant of the Burseraceae family, widely used in traditional Malian medicine. The aim of this study was to carry out phytochemical screening and to evaluate the antioxidant activity of the extracts. The plant material consisted of root bark and leaves. These parts were collected in Ségué, Bankass Prefecture, in the Mopti region of Mali. The extracts were prepared by reflux heating and Soxhlet extraction. Phytochemical groups were identified using tube colour reactions.

Phytoremediation by potted plants is widely promoted as a low-cost remedy for indoor volatile organic compounds (VOCs), yet the supporting evidence comes from sealed-chamber studies lasting many hours, whereas school-level replications typically use short protocols without leak testing or sensor characterisation.

La mobilité touristique estivale des jeunes ruraux vers les grandes villes côtières se situe à la croisée de la bioclimatologie humaine et de la géographie du tourisme. Cette recherche évalue le choc bioclimatique subi par les jeunes vacanciers à Cotonou en juillet-août et identifie leurs stratégies d’adaptation face à l’inconfort thermique.

RNA biogenesis is a highly coordinated and fundamental biological process that regulates the synthesis, processing, modification, maturation, transport and turnover of cellular RNA molecules. The coordinated production of wide range of RNAs and other non-coding RNAs is essential for maintaining gene expression, protein synthesis and cellular homeostasis. Ribosome quality control (RQC) provides an important protective mechanism by detecting defective or stalled ribosomes, resolving ribosome collisions, and eliminating abnormal nascent proteins and dysfunctional ribosomal components.

The objective of this study is to remove copper and lead by optimizing operating parameters such as pH, electrolysis time and inter-electrode distance using the electrocoagulation process on a pilot scale with aluminum electrodes. During this experiment, the pH was varied between 1.8 and 9; the electrolysis time between 0 and 25 hours and the inter-electrode distance between 20 and 25 cm in order to obtain the best operating conditions. The electrical energy consumed and the operating cost were also evaluated.

Malgré une prise en charge multimodale, le glioblastoma (GBM) reste une tumeur cérébrale agressive de très mauvais pronostic, en raison notamment de la barrière hémato-encéphalique, de l'hétérogénéité tumorale et d'une délivrance intracellulaire insuffisante des agents thérapeutiques. Le GBM, qui touche principalement l'adulte (âge médian ~65 ans) avec une incidence de 3-4/100 000 habitants, présente un phénotype mésenchymateux caractérisé par une surexpression de la vimentine, en faisant une cible de choix pour des peptides dérivés du cytosquelette.

The story of technology is always in a continuous process. Every era has witnessed various innovations that changed human life where the roots of technology are in the invention of the wheel. From the very beginning, technology has aimed a new lifestyle centred on connectivity and convenience for mankind. While it brings many benefits, it also requires responsibility and balance. As we look toward the future, embracing technology wisely will be key to building a more connected, innovative, and humane world.

This study examines the impact of key socio-economic factors—education, work experience, gender, and age—on income, with a particular focus on capturing heterogeneity across the income distribution. A structured preprocessing framework is employed, including missing value treatment, categorical variable transformation, and outlier detection using the Interquartile Range (IQR) method. The dataset is divided into training (80%) and test (20%) subsets to assess model generalizability, and K-fold cross-validation is applied to evaluate predictive stability.

G4 are guanine-rich non-canonical nucleic acids conformations in eukaryotic genomes. The cellular, genomic and physiological significance of G4s was skeptical a decade ago. Computational and experimental methods have offered new perspectives into their roles. Biophysical research has demonstrated relationship between the G4 sequence content, topology, and thermodynamic stability. G4s are primarily located in genomic areas such as telomeres, enhancers, and gene promoters. G4s are involved in transcriptional regulation and chromatin mediated epigenetic genome changes.
