Upper Cretaceous–Lower Paleogene successions along the southern Tethyan margin record the combined effects of global environmental perturbations, relative sea-level change, and regional tectonism. This study reconstructs paleoenvironmental and sequence-stratigraphic evolution across Maastrichtian–Ypresian strata in four Esh El-Mellaha sections, northern Eastern Desert, Egypt, using integrated lithostratigraphy, microfacies, be...

Macrolophus caliginosus Wagner (Hemiptera: Heteroptera: Miridae), a predatory bug widely used in biological control against whiteflies and spider mites, also shows strong efficiency on aphids, with females consuming on average ~43.2 first-instar Aphis gossypii nymphs per day under laboratory conditions. This study evaluates the predation capacity and functional response of M. caliginosus to varying densities of Aphis craccivor...

Despite Saudi Arabia being an interesting area from a floristic perspective, its vegetation is still relatively poorly studied. This certainly applies to the Hijaz Mountains and adjacent coastal zones. We aim to describe the flora and vegetation of the foothills of the Hijaz Mountains regarding the environmental conditions. Hijaz Mountains and adjacent coastal zones, Saudi Arabia. We studied the vegetation at the Hijaz Mountai...

Recombination-activating gene 1 (RAG1) is a vital player in V(D)J recombination, a fundamental process in primary B cell and T cell receptor diversification of the adaptive immune system. Current vertebrate RAG evolved from RAG transposon; however, it has been modified to play a crucial role in the adaptive system instead of being irreversibly silenced by CpG methylation. By interrogating a range of publicly available datasets...

Parkinson’s disease (PD) is a chronic and ongoing neurological condition. Unfortunately, as the dopaminergic terminals continue to deteriorate, the effectiveness of anti-Parkinson therapy decreases. This study aimed to examine the effects of BM-MSCs-derived exosomes in rats induced with Parkinson’s disease. The goal was to determine their potential for neurogenic repair and functional restoration. Forty male albino rats were d...

This study was conducted to evaluate the effects of supplementation of exogenous enzymes in broiler diets that includes fermented canola meal on performance, nutrient digestibility, biochemical indication, antioxidative capacity, digestive enzyme activity, immune responses, and gut health. Five hundred 1-day-old Ross 308 broiler chicks were randomly allocated into five experimental groups (5 replicate/group), the first group:...
