Hemorrhoids are anorectal disorders characterized by venous dilation and mucosal inflammation. Recent genomic analyses identify nitric oxide synthase-3 (NOS3) as a key risk gene; sapropterin—an FDA-approved 6-R-tetrahydrobiopterin analog for phenylketonuria—is predicted to down-regulate this pathway. Objective: To evaluate the anti-inflammatory effect of sapropterin on NOS3, cyclo-oxygenas…
Mesenchymal stem cells (MSCs) are well known for their significant therapeutic potential due to several key biological characteristics. However, MSCs have a limited lifespan during in vitro expansion. This limitation is primarily due to the accumulation of reactive oxygen species (ROS), which triggers oxidative stress and can potentially damage biomolecules within MSCs. The objective of this st…
Male infertility is a significant reproductive health issue often associated with sperm quality. One approach to understanding its molecular mechanism is by exploring epigenetic regulation, particularly DNA methylation and gene expression. MEST is an imprinted gene essential for spermatogenesis and has been implicated in infertility, especially in oligozoospermia. Methods: This case contro…
Oligozoospermia, occurs in 34.14% of male infertility cases, define as sperm concentration counted less than 15 million sperm/mL/ejaculation. One of the factor that affects sperm concentration is epigenetic factors, including DNA methylation. We hypotized that sperm concentration is affected by the DNA methylation of H19 gene, a significant gene in fetal growth and development, especially in th…
Background: Mesenchymal stem cells (MSCs) have great potential for therapy due to their self-renewal, differentiation and immunoregulatory capacities. The proliferative and functional activity of MSCs as well as its immunomodulatory properties can be impaired as a result of oxidative stress-induced senescence during long-term culture of MSCs. Modification of MSCs culture is very important to im…

NURUL AZIZAH, Student ID: 2210246766, The Anti-Inflammatory Effect of Metformin Through Modulation of Cyclooxygenase-2 (COX-2) and Interleukin-10 (IL-10) in a Hemorrhoid Rat Model, supervised by Dr. Darmawi M.Biomed., PhD, and Dr. M. Yulis Hamidy, M.Kes, M.Pd.Ked., Sp.K.K.L.P. Background: Hemorrhoids are a medical condition characterized by inflammation and dilation of blood vessels around the…
Hemorrhoids are a condition characterized by the dilation of venous blood vessels in the anorectal region, involving inflammation, thrombosis, and bleeding. Anti-inflammatory treatments are crucial in preventing the progression of hemorrhoids. Metformin, primarily used as an antihyperglycemic drug, also has anti-inflammatory properties. Its use in patients with type 2 diabetes shows potential i…
Introduction: Diterpene quinone-derived compounds are proven to have antibacterial activity. However, their mechanism of action is unknown. This study aims to determine the mechanism of antibacterial action of a diterpene quinone derivatives (67DOR, 6O7AR) on S. aureus and E. coli through in vitro and in silico assays. Methods: This study is a laboratory experimental through in vitro and in si…
