Biliary atresia (BA), a severe pediatric liver disease of unknown etiology, causes neonatal jaundice, progressive cholestasis, and life-threatening liver fibrosis. Emerging evidence suggests microRNAs (miRNAs) – small non-coding RNAs that regulate gene expression by binding target mRNAs may play a role in BA pathogenesis. Circulating miRNAs have shown diagnostic potential for various diseases, prompting our investigation of miR-21 and miR-19 as potential biomarkers in BA. We conducted a case-con [...]

This study investigated three novel complete blood count–derived inflammatory biomarkers Systemic Immune-Inflammation Index (SII), Systemic Inflammation Response Index (SIRI), and Pan-Immune-Inflammation Value (PIV) and their relationship with clinical features of Behçet’s Disease (BD). Established markers, including neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), were also analyzed. Seventy HLA-B51–positive BD patients and 114 HL [...]

An episomal vector is a plasmid- or virus-based vector that is present extrachromosomally in cells after transfection. Although it disappears during cell proliferation, it can exist in non-dividing cells, such as neuronal and muscular cells, and continues to express a gene of interest (GOI). Such episomal vectors are usually based on sequences from DNA viruses such as bovine papillomavirus 1 and Epstein-Barr virus. When cells are transfected with an episomal vector harboring a drug-resistance ge [...]

Wheat constitutes the backbone of global food supplies, and its production is directly linked to the food and nutritional security of the mounting population. Wheat is vulnerable to abiotic stresses like heat, salinity, and drought. These abiotic stresses tend to reduce the food security of the increasing population by reducing wheat production and nutritional quality. Among abiotic stresses, salinity stress (SS) has emerged as the most prevailing stress in modern high-input wheat farming system [...]

Interleukin-8 (IL-8), a pro-inflammatory cytokine, plays a critical role in immune modulation in poultry and has potential applications in veterinary and human medicine. This study investigated the effects of dietary supplementation with mealworm (Tenebrio molitor), probiotics, or their combination on IL-8 gene expression in the livers and spleens of broiler chickens. A total of 160 one-day-old broiler chickens (Ross 308 strain) were assigned to four treatments (basal diet, [...]

Ebstein's anomaly (EA) is a rare form of congenital heart disease (CHD), characterized by abnormal cardiac anatomy involving a defective tricuspid valve (TV), resulting in tricuspid regurgitation (TR) and cyanosis. EA is represented in different case scenarios with varying degrees of complexity across various age groups. It usually affects 0.2-0.7 out of 10,000 live births and accounts for 0.3%-0.6% of all CHD cases. While its occurrence is mainly sporadic, evidence from multiple studies suggest [...]

Non-small cell lung cancer (NSCLC), accounting for approximately 85% of lung cancer cases, remains a leading cause of cancer-related mortality. Genetic alteration such as EGFR mutations, tobacco exposure, and resistance to apoptosis, slows its progression and limits therapeutic success. Although targeted therapies and immunotherapy have improved outcomes for select patients, resistance remains a major challenge, highlighting the need for more effective treatments. This study investigated the pot [...]

A molecular-level understanding of cancer is essential for the development of effective therapies. Constructing protein-protein interaction (PPI) networks offers a valuable approach to identifying dysregulated driver genes and potential therapeutic targets. In this study, we modeled cancer PPI networks as metric spaces and applied mathematical and computational algorithms to analyze their structural and functional properties. Our findings reveal that these networks share a conserved architecture [...]
