A review on cyclin-dependent kinase 5: An emerging drug target for neurodegenerative diseases.

Cyclin-dependent kinase 5 (CDK5) is the serine/threonine-directed kinase mainly found in the brain and plays a significant role in developing the central nervous system. Recent evidence suggests that CDK5 is activated by specific cyclins regulating its expression and activity. P35 and p39 activate CDK5, and their proteolytic degradation produces p25 and p29, which are stable products involved in the hyperphosphorylation of tau protein, a significant hallmark of various neurological diseases.

Members of Ensifer and Rhizobium genera are new bacterial endosymbionts nodulating Pisum sativum (L.).

A total of 84 Pisum sativum legume nodulating bacteria (LNB) were isolated from seven geographical sites from southern Tunisia. Phylogenetic analyses based on partial sequences of 16S rRNA gene and the housekeeping genes glnII, and recA grouped strains into six clusters, four of which belonged to the genus Rhizobium and two to the Ensifer genus. Among Rhizobium clusters, 41 strains were affiliated to Rhizobium leguminosarum, two strains to R.

They characterize inside the body due to several factors such as diet, nutrition, xenobiotic substances, and microbial infections. Several studies have shown that gut microbiota can induce resistance against pathogens and regulate the immune system.

Aizoon extract as an eco-friendly corrosion inhibitor for stainless steel 430 in HCl solution.

Aizoon extract is used as an eco-friendly anti-corrosive material for stainless steel 430 (SS430) in a 2 M hydrochloric acid solution.

Evaluation of inhaled nitric oxide (iNO) treatment for moderate-to-severe ARDS in critically ill patients with COVID-19: a multicenter cohort study.

Background: Inhaled nitric oxide (iNO) is used as rescue therapy in patients with refractory hypoxemia due to severe COVID-19 acute respiratory distress syndrome (ARDS) despite the recommendation against the use of this treatment. To date, the effect of iNO on the clinical outcomes of critically ill COVID-19 patients with moderate-to-severe ARDS remains arguable. Therefore, this study aimed to evaluate the use of iNO in critically ill COVID-19 patients with moderate-to-severe ARDS.

Vancomycin as an Antibacterial Agent Capped with Silver Nanoparticles: An Experimental Potential Analysis.

For the treatment of various infections, a variety of antimicrobial drugs are formulated.

Identification of 11-Hydroxytephrosin and Torosaflavone A as Potential Inhibitors of 3-Phosphoinositide-Dependent Protein Kinase 1 (PDPK1): Toward Anticancer Drug Discovery.

The 3-phosphoinositide-dependent protein kinase 1 (PDPK1) has a significant role in cancer progression and metastasis as well as other inflammatory disorders, and has been proposed as a promising therapeutic target for several malignancies. In this work, we conducted a systematic virtual screening of natural compounds from the IMPPAT database to identify possible PDPK1 inhibitors. Primarily, the Lipinski rules, ADMET, and PAINS filter were applied and then the binding affinities, docking scores, and selectivity were carried out to find effective hits against PDPK1.

Evaluation of anti-angiogenic agent F16 for targeting glioblastoma xenograft tumors.

Glioblastoma Multiforme (GBM) is one of the most aggressive and lethal types of all cancers, with an average 5-year survival rate of 5%. Since GBM tumors are highly vascularized tumors, and their growth is angiogenesis-dependent, antagonizing tumor angiogenesis by using angiogenesis inhibitors were considered as one of the promising approaches. In this context, intensive preclinical evaluation of a novel small molecule named F16 has exhibited potent anti-angiogenic and anti-tumor activities by selectively antagonizing Vascular Endothelial Growth Factor Receptor (VEGFR).
