Epigenetic mechanisms regulate and stabilize a broad range of biological processes without altering the primary DNA sequence. This regulation is achieved through DNA methylation, post-translational histone modifications (PTMs), and non-coding RNAs (ncRNAs). These mechanisms facilitate rapid and flexible changes in gene expression in response to environmental cues such as temperature, humidity, nutrition, and chemical exposure. Upon detection of these signals, the neuroendocrine system relays the...

Hsi-sheng Chi’s 1976 English monograph *Warlord Politics in China, 1916-1928* was the first to systematically construct an analytical paradigm of “relation-culture” in the study of Beiyang warlord politics. This research broke away from the traditional class-based historical view and regarded the warlord group as a dynamically operating power balance system. Its core innovations lie in: 1) employing political science and sociological theories to deconstruct warlord factions, proposing three sust...

Round pneumonia is a rare clinical entity in adults and may radiographically resemble malignant lung lesions, often leading to diagnostic uncertainty. We present the case of a geriatric patient with a background of diabetes mellitus, hypertension and lichen sclerosis who arrived with a five-day history of fever, generalised body ache, right ear pain, fatigue and decreased appetite. She was febrile with mild tachycardia, and her investigations revealed leukocytosis, significantly raised C-reactiv...

Introduction: The integration of lasers in dental practice has experienced real extent thanks to the advantages and facilities they present. This technology has shown remarkable results namely in the surgery of soft tissues as well as hard tissues. In dentistry, and essentially in joint prostheses, the most lasers used are Diode laser and Erbium laser. These lasers facilitated interventions and optimizing treatment plans. Objective: The main purpose of our systematic review was to show the contr...

The WHO lists H. pylori as one of the 20 pathogens that pose the greatest threat to human health due to their antibiotic resistance and classifies it as a Group 1 gastric carcinogen, directly linked to stomach cancer. This study aimed to determine the prevalence of H. pylori infection among students in Lubumbashi and to test the associations between serological results and sex, age, and the presence of gastritis attack. This was a descriptive cross-sectional study conducted fro...

Staphylococcus aureus is an important foodborne pathogen that is of major concern to public health especially when it becomes resistant to a last-line drug of choice like vancomycin. As the use of plant derived drinks such as soy milk have grown, the issue of microbial contamination and antimicrobial resistance is also of greater concern particularly in regions with little regulations. This study was done to determine the occurrence of Vancomycin-Resistant Staphylococcus aureus (VRSA) in soy mil...
