Article Abstract

Two new taxoids (5 and 6) were obtained by isolating impurities in aziditaxel, and their structures were characterized based on data analysis of (1)H NMR, (13)C NMR, HPLC-MS, and through comparison with literature. In order to test their cytotoxicities against human nonsmall lung cancer cell lines (A549), sufficient amounts of compounds 5 and 6 were obtained by semi-synthesis and both of them showed equipotent cytotoxiesty compared with taxol, docetaxel, and aziditaxel.

Background: Actinomyces graevenitzii is a relatively uncommon Actinomyces species, which is an oral species and predominantly recovered from respiratory locations [1,2]. It is a gram-positive anaerobic bacteria or microaerobic filamentation bacteria, which can induce pyogenic and granulomatous inflammation characterized by swelling and concomitant pus, sinus formation, and the formation of yellow sulfur granules. All tissues and organs can be infected; the most common type involves the neck and face (55%), followed by the abdominal and pelvic cavities (20%).

Taenia crassiceps (Zeder, 1800), a zoonotic cestode with a wide geographical distribution, utilises canids as definitive hosts and small rodents as intermediate hosts. However, accidental infections in non-human primates, particularly in captive lemurs, have been increasingly documented. In this case report, we describe the first documented case of cysticercosis caused by the larval stage of T.

The present investigation elucidates the therapeutic potential of glycyrrhizin, the predominant triterpene saponin isolated from (licorice), in the management of systemic lupus erythematosus (SLE), an autoimmune disorder characterized by multisystemic involvement and therapeutic recalcitrance. Comprehensive interrogation of multiple disease-specific databases facilitated the identification of crucial SLE-associated molecular targets and hub genes, with MAPK1, MAPK3, TP53, JUN, and JAK2 demonstrating the highest degree of network centrality. Subsequent molecular docking simulations and binding affinity assessments revealed compounds with exceptional complementarity to these pivotal molecular targets, establishing as a pharmacologically promising botanical source and glycyrrhizin as its principal bioactive constituent meriting comprehensive mechanistic investigation.

Breast cancer metastasis and relapse remain uncontrollable despite significant advancements in early diagnosis and treatment, resulting in increased mortality. Breast cancer is the most frequently diagnosed cancer in women worldwide and has become the leading cause of cancer-related deaths. Cancer stem cells (CSCs) may play significant roles in tumor initiation, maintenance, invasion, relapse, metastasis, and therapy resistance.

Background: Hospital surfaces are critical reservoirs of multidrug-resistant pathogens, including third-generation cephalosporin-resistant Gram-negative bacteria (3GC-R-GNB), significantly contributing to healthcare-associated infections (HCAIs). This challenge is pronounced in low- and middle-income countries, where resource constraints limit effective infection prevention and control (IPC) measures. This study screened hospital surfaces for 3GC-R-GNB in selected District Hospitals (DHs) in Mwanza, Tanzania.
