Background: The growth in obesity and rates of abdominal obesity in developing countries is due to the dietary transition, meaning a shift from traditional, fiber-rich diets to Westernized diets high in processed foods, sugars, and unhealthy fats. Environmental changes, such as improving the quality of dietary fat consumed, may be useful in preventing or mitigating the obesity or unhealthy obesity phenotype in individuals with a genetic predisposition, although this has not yet been confirmed. Therefore, in this study, we investigated how dietary fat quality indices with metabolically healthy obesity (MHO) or metabolically unhealthy obesity (MUO) based on the Karelis criterion interact with genetic susceptibility in Iranian female adults.

Targeting ferroptosis in gastrointestinal tumors: Interplay of iron-dependent cell death and autophagy.

Mol Cell Probes

January 2025

Farhikhtegan Medical Convergence Sciences Research Center, Farhikhtegan Hospital Tehran Medical Sciences, Islamic Azad University, Tehran, Iran; Department of Genetics, Faculty of Advanced Science and Technology, Tehran Medical Sciences, Islamic Azad University, Tehran, Iran. Electronic address:

Ferroptosis is a regulated cell death mechanism distinct from apoptosis, autophagy, and necroptosis, marked by iron accumulation and lipid peroxidation. Since its identification in 2012, it has developed into a potential therapeutic target, especially concerning GI disorders like PC, HCC, GC, and CRC. This interest arises from the distinctive role of ferroptosis in the progression of diseases, presenting a new avenue for treatment where existing therapies fall short.

Bio-Obturation for Internal Root Resorption in Contralateral Mandibular Molars: A Five-Year Case Study.

Cureus

December 2024

Endodontics, Iranian Center for Endodontic Research, Research Institute of Dental Sciences, Shahid Beheshti University of Medical Sciences, Tehran, IRN.

Internal root resorption (IRR) is a rare but complex condition characterized by progressive destruction of the internal dentin walls, typically resulting from chronic pulp inflammation, trauma, or infection. Managing apical IRR, particularly in teeth with extensive apical lesions, presents significant challenges due to the limitations of traditional root canal treatment (RCT) and obturation techniques. This report discusses the nonsurgical management of two contralateral mandibular first molars in a 49-year-old male patient, both exhibiting apical IRR and large endodontic lesions.

Predictive performance of noninvasive factors for liver fibrosis in severe obesity: a screening based on machine learning models.

J Diabetes Metab Disord

June 2025

Center for Global Health Research, Saveetha Institute of Medical and Technical Sciences, Saveetha Medical College and Hospitals, Saveetha University, Chennai, India.

Objectives: Liver fibrosis resulting from nonalcoholic fatty liver disease (NAFLD) and metabolic disorders is highly prevalent in patients with severe obesity and poses a significant health challenge. However, there is a lack of data on the effectiveness of noninvasive factors in predicting liver fibrosis. Therefore, this study aimed to assess the relationship between these factors and liver fibrosis through a machine learning approach.

Cyclooxygenases (COX) play a pivotal role in inflammation and are responsible for the production of prostaglandins (PGs). Two types of COXs have been identified as key biological targets for drug design: Constitutive COX-1 and inducible COX-2. Nonsteroidal anti-inflammatory drugs (NSAIDs) target COX-1, while selective COX-2 inhibitors are designed for COX-2.

Article Synopsis
  • Advanced glycation end products (AGEs), mainly derived from methylglyoxal (MG), are linked to neurological disorders such as Alzheimer's disease.
  • The study assessed the effects of aminoguanidine (AG), semicarbazide (SC), and thiosemicarbazide (TSC) on MG-induced toxicity in rats, revealing that MG exposure led to memory issues, increased anxiety, and brain cell damage.
  • Semicarbazide showed the most promise in preventing memory problems, while AG and TSC alleviated anxiety and improved neuronal survival in specific brain regions affected by MG.
  • Further research is needed to understand how these compounds protect against neurobehavioral toxicity.
