The increased production of beta-amyloid marks Alzheimer's disease. PPAR-γ shows involvement in Alzheimer's disease. PPAR-γ Gene is suspected to reduce beta-amyloid plaques and reduce inflammation and oxidative stress in Alzheimer's disease. Mesenchymal Stem Cells Wharton's Jelly (MSC-WJ) is expected to increase the PPAR-γ Gene expression. Objective: To observed the PPAR-γ Gene expression in Alzheimer's Mice. Methods: The mice are induced using AlCl3 and were given MSC-WJ. This study was an experimental study with a post-test-only control group design on 18 samples of RNA from Alzheimer's mice that were divided into 3 groups. Negative control group (K-), positive control group (K+), and experimented group (P). The mean of PPAR-γ gene expression was obtained by comparing the PPAR-γ gene with the GAPDH gene. This study used semiquantitative methods using ImageJ. Data analysis was used with the Kruskal-Wallis test. It is significant if the value is <0,05. Results: The mean ratio of PPAR-γ gene expression that was obtained in K-, K+, and P were 0.12, 0.06, and 0.08, respectively. There were significant differences between each group, with a p-value of 0,023 (p<0,05). Conclusion: Giving MSC-WJ could increase the PPAR-γ gene expression. Further study using real-time PCR is highly needed to increase the MSC-WJ treatment in patients with Alzheimer's disease.Keywords: Alzheimer disease, MSC-WJ, PPAR- γ

Introduction: Miscarriage is a reflection of the low quality of health in pregnant women. The incidence of miscarriage in the world accounts for 23 million (15%) of the 130 million births per year and up to 80% of miscarriages occur in the first trimester of pregnancy. Miscarriage will affect a woman's social, physical, and psychological. The complexity of the negative impact of miscarriage makes it necessary to pay special attention. Biomarker examination is needed to more accurately identify pregnancies at risk of miscarriage before the appearance of clinical symptoms. The use of fetal fibronectin (fFN) levels have been used as a marker of unexpected labor and as evidence of premature rupture of the fetal membranes. Normally fFN can be detected in cervical and vaginal secretions at <20 weeks gestation. The presence of fFN at >22 weeks gestation indicates disruption of the uteroplacental surface. Therefore, if screening for fibronectin levels using the Enzyme-Linked Immunosorbent Assay (ELISA) test can be carried out in the first trimester of pregnancy, there is a high possibility that miscarriage can be prevented.Method: The type of research is analytical observational research with a cross-sectional research design. The stored samples were examined for fibronectin levels using the ELISA test, which included 21 blood serum samples from normal pregnancy patients in the first trimester and 21 miscarriage samples.Results: The results of the ELISA test produced an average first-trimester normal pregnancy fibronectin level of 118.8 Â± 18.4 ng/mL while the miscarriage fibronectin level was 208.2 Â± 152.0 ng/mL. Data analysis using the Mann-Whitney test obtained a p-value = 0.138, which means there was no significant difference in fibronectin levels between normal pregnancy in the first trimester and miscarriage.Conclusion: This study concludes that fibronectin levels are not specific biomarkers in detecting miscarriage in the first trimester of pregnancy.

Background: Uterine smooth muscle tumor of uncertain malignant potential (STUMP) presents a diagnostic dilemma, especially in Southeast Asian populations, where delayed presentation often leads to advanced tumor burden. This study aimed to characterize the clinicopathological profile of STUMP in Indonesia using the 2021 WHO Classification and modified Stanford parameters. Methods: A descriptive study analyzed 37 STUMP cases diagnosed between 2023 and 2025 at a tertiary referral center in West Sumatra. A panel of pathologists re-evaluated archival slides for atypia, mitotic activity, necrosis, and growth patterns, establishing inter-observer reliability. Fisher’s Exact Test was employed to correlate tumor size with morphological markers of aggression. Results: The cohort demonstrated a distinct large-mass phenotype, with 54.1% of tumors exceeding 10 cm and a median diameter of 14.5 cm. Pathological review classified 56.8% of cases into WHO Group 4 (atypia with ambiguous mitosis). A statistically significant correlation was identified between tumor size >10 cm and the presence of infiltrative growth margins (81.1%; p=0.034). Conclusion: Indonesian STUMP cases are distinctively characterized by massive size and high rates of infiltrative growth, likely driven by prolonged natural history. The prevalence of ambiguous mitotic figures underscores the utility of the WHO Group 4 category in resource-limited settings. These findings advocate for aggressive surgical management and wider resection margins in large-mass variants to mitigate local recurrence risk.
