Background/Aims: This study aims to investigate the association between Binge Eating Disorder and functional dyspepsia in a Mexican population, focusing on symptomatology and demographic characteristics. Methods: We conducted a cross-sectional study on 1016 subjects, evaluating binge eating disorder (BED) and functional dyspepsia based on the Rome IV criteria. Data collection included sociodemographic information, gastrointestinal symptom severity, and anxiety/depression screening using validated tools. A multivariate logistic regression analysis with the 2 test was conducted for comparison analysis. Results: The prevalence of dyspepsia in BED was 53.6% (95% CI, 46-56). Postprandial fullness (OR, 1.52; 95% CI, 1.06-2.17; P = 0.021) and overlap syndrome (OR, 1.80; 95% CI, 1.25-2.60; P = 0.002) were significantly associated with BED. Patients with BED also presented more severe postprandial distress syndrome (P = 0.027). Anxiety was prevalent in BED patients, while depression was more prominent in patients with BED and dyspepsia overlap. Conclusions BED patients have a high prevalence of dyspepsia with an association between postprandial fullness and this eating disorder. BED appears to be more prevalent in younger individuals and males. These findings underscore the importance of considering dyspepsia in the management of BED and highlight the need for further research on this association.

Background: The study of small-molecule compounds with antitumor activity involves several crucial steps. These include determining their selective effects on cancer cells, understanding the type of cell death they induce, identifying the activated signaling pathways, pinpointing the target molecules, and elucidating the mechanisms of action. Among the plant-derived compounds with anticancer properties, flavonoids are notable for their ease of isolation and their abundance in food. Apigetrin, a representative flavonoid, is a secondary metabolite found in plants, and our previous study indicated that its anticancer selectivity index was 13.1. However, the specific mechanism by which apigetrin inhibits leukemia cell growth remains unclear. Aim: To study of the inhibitory action of apigenin on leukemia cell culture Materials and Methods: In this study, we evaluated the apoptosis of cells using flow cytometry and investigated the in volvement of the caspase pathway through the use of pancaspase inhibitors to explore the effects of apigetrin on leukemia cell growth. Results: After incubating leukemia RAW264.7 cells with 30 μM apigetrin for 24 and 48 hours, we did not detect any apoptosis through Annexin V and PI staining by flow cytometry. We compared the number of viable cells using the MTT assay after 24-hour treatment of apigetrin with or without pretreatment of Z-VAD, a pancaspase inhibitor, for 30 minutes. The results indicated that the pancaspase inhibitor did not reduce the inhibitory effect of apigetrin on the growth of RAW264.7 cells. In contrast, the positive control group, treated with doxorubicin—which induces apoptosis—showed not only significant apoptosis but also a reduction of the pancaspase inhibitor on the cell growth inhibition. Therefore, these data suggested that apigetrin likely has a cytostatic effect or inhibits the cell cycle rather than being cytotoxic. Future research should focus on determining which stage of the cell cycle RAW264.7 cells treated with apigetrin are in, as well as studying the signaling pathways involved in the cell cycle. Conclusions Apigetrin inhibits the proliferation of RAW264.7 leukemia cells in a caspase-independent and non-apoptotic manner.

Background: In recent years, the incidence of liver diseases due to complications of non-alcoholic fatty liver disease (NAFLD) has shown a significant upward trend in Southeast Asian countries. NAFLD is a hepatic disorder characterized by lipid accumulation in the microstructure of the liver in individuals who consume little to no alcohol. It is often associated with insulin resistance and is diagnosed when steatosis affects more than 5% of hepatocytes histologically, or when the fat signal intensity on MRI exceeds 5.6%, based on fat-to-water ratio measurements. In Mongolia, histological studies using frozen liver sections with routine and special staining techniques are limited, highlighting the necessity of this study. Aim: To determine and compare the degree of steatosis and fibrosis in frozen liver tissue samples of patients with NAFLD through histological analysis. Materials and Methods: This study was conducted at the the Department of Anatomy, School of Biomedicine and Bio medical Research Institute of MNUMS in collaboration with the Second State Central Hospital. Ethical approval was obtained from the Research Ethics Committee of MNUMS (Protocol No. 2024/3-06). All procedures adhered strictly to laboratory biosafety protocols. Participants were selected among patients undergoing elective laparoscopic cholecystectomy, from whom informed consent was obtained. Based on inclusion criteria, five participants were grouped as follows: healthy control (n=1), NAFLD without fibrosis (n=2), and NAFLD with fibrosis (n=2). Liver biopsies (approx. 1 cm in size) were obtained intraoperatively, immediately deep-frozen in liquid nitrogen, and prepared for histological evaluation. Results: In patients with NAFLD compared to the healthy liver group, disruption of hepatocyte columnar architecture and mild periportal lymphocytic infiltration were observed. Oil Red O staining revealed 34–66% micro- and macrovesicular steatosis, corresponding to grade 2 steatosis. Masson’s trichrome staining showed no fibrotic changes in perivenular or periportal areas (Ishak grade 0/4) at this stage. However, upon progression to grade 3 steatosis, early-stage fibrosis was observed in both perivenular and periportal regions (Ishak grade 1/4). Further progression to stage 4 fibrosis was characterized by the development of connective tissue septa, although no significant changes in droplet size were observed. Conclusions 1. Increasing stages of fibrosis are not directly influenced by the severity of hepatic steatosis in NAFLD. 2. Although the degree of steatosis increases, the absence of corresponding fibrotic changes in early stages indicates a complex progression pattern of NAFLD requiring further investigation.

Complete androgen insensitivity syndrome (CAIS), also known as Morris syndrome, is a rare X-linked recessive disorder characterized by a 46XY karyotype and a female external phenotype. We present the case of a 32-year-old patient who presented to Unimed International Hospital in 2024 with primary amenorrhea, infertility, and chronic pelvic pain. Clinical examination, imaging, and laboratory investigations led to the diagnosis of CAIS. Laparoscopic surgery was performed to remove bilateral gonadal structures and a cystic mass on the left side. Histopathological analysis revealed testicular tissue and a serous cystadenoma originating from the left mesonephric remnant. Following gonadectomy, hormone replacement therapy was initiated, resulting in stabilization of hormone levels. This rare case highlights the possibility of mesonephric remnant-derived cystadenoma in CAIS and underscores the diagnostic value of cytogenetic and histological evaluations, especially in distinguishing between ovarian and testicular tissue when imaging findings are inconclusive.

Background: Cancer incidence and mortality are steadily increasing both globally and in Mongolia. As these rates rise, traditional Mongolian medicine has long utilized herbal formulas for the treatment of gastric and esophageal cancers and precancerous conditions. One such formulation—Hot Natured 3 Herbs (HN3H)—comprises three species from the Ranunculaceae family: Atragene sibirica L., Ranunculus repens L., and Pulsatilla bungeana L.. However, scientific validation of its anti-tumor effects is essential. This study aimed to investigate the effect of HN3H in a tumor-induced animal model. Aim: To identify the biologically active compounds of HN3H and evaluate their effect in an experimentally induced tumor model in animals. Materials and Methods: The three herbs comprising HN3H—Atragene sibirica L., Ranunculus repens L., and Pulsatilla bungeana L.—were collected during their flowering stage (May–June) in Khishig-Undur, Bulgan province, and dried according to official procedures. Extraction was carried out by maceration in 96% ethanol at a 1:10 ratio. The concentrated extract was suspended in water (1:1) and successively fractionated with dichloromethane, ethyl acetate, butanol, chloroform, and n-hexane. The study was approved by the Research Ethics Committee of the Mongolian National University of Medical Sciences (Protocol №2020/03-04). A colorectal cancer model was established by subcutaneous injection of MC-38 cells (Kerafast, USA) into C57BL/6 mice. Immunohistochemistry was performed using CK20, CDX2, Ki67, and p53 antibodies at 1:100 and 1:200 dilutions. Results: The ethanol extract of HN3H contained 2.98±0.04% total phenolics and 2.16±0.05% total flavonoids. Body weight and tumor volume were measured daily with three repetitions. All groups showed a time-dependent increase in body weight. Mice in groups 1A and 1B received ethanol extract at 50 and 100 mg/kg doses; groups 2A and 2B received dichloromethane extract at the same doses. The negative control group was administered 0.5 mg/kg PBS orally, while the positive control group received intraperitoneal injections of 5-fluorouracil (5FU) at 10 mg/kg twice a week. Tumor growth increased in a time-dependent manner across groups. Compared to the negative control, tumor volumes in four treatment groups showed statistically significant reduction (p˂0.05), while no significant difference was observed when compared to the positive control (p=0.08). Histological analysis revealed necrosis in all groups, with variation in extent. Conclusion The ethanol extract of HN3H exhibited moderate levels of phenolic compounds and a high concentration of flavonoids. HN3H extract inhibited tumor progression and activated lymphocyte-predominant inflammation in tumor tissues, indicating potential anti-tumor activity (p˂0.05).
