Research
Hepatocellular steatosis, an early stage within the non-alcoholic fatty liver disease (NAFLD) spectrum, is characterized by excessive lipid accumulation and oxidative stress in hepatocytes.
source →Introduction The development of novel quinolin-2(1H)-one-fused 1,3,4-thiadiazole heterocyclic hybrids was achieved through structural optimization as potential antimicrobial/anti- TB agents.
source →Oral delivery of peptide therapeutics remains challenging due to gastrointestinal (GI) degradation and poor intestinal absorption.
source →Dupilumab, a monoclonal antibody blocking interleukin-4/interleukin-13 signaling, was associated with neuroinflammatory syndromes in 4 children treated for atopic dermatitis. Individuals exhibited behavioral changes, language impairment, and neurodiagnostic abnormalities 2-6 months after treatment initiation.
source →Therapeutic peptides are short chains of amino acids used to treat metabolic and endocrine conditions such as obesity and type 2 diabetes.
source →NLRP3 functions as a critical intracellular danger sensor for inflammasome activation, playing a crucial role in autoimmune diseases. Vitiligo progression has been linked to NLRP3, yet its specific involvement in melanocytes of vitiligo remains poorly understood.
source →The pursuit of pharmacological enhancement in sport has evolved from the widespread use of anabolic-androgenic steroids (AAS) to novel agents such as peptides and peptide analogues.
source →Oral cancer ranks among the most prevalent malignant tumors of the head and neck, comprising 1%-2% of all global malignancies.
source →Background There is a concerning trend of misinformation of healthcare related content on social media. Recent studies have examined themes and narratives about Crohn's disease but have not quantitatively assessed the accuracy and quality of content on Instagram Reels.
source →Airborne particulate matter (PM) poses a major environmental risk that impairs skin health by triggering oxidative stress, inflammation, and cell death.
source →Cardiovascular disease (CVD) is a leading cause of death globally, and vascular calcification (VC) is an important independent risk factor for predicting CVD. Currently, there are no established therapeutic strategies for the treatment of VC.
