OBJECTIVES: Type 2 diabetic Mellitus (T2DM) is the most common systemic and endocrine disease in humans, and diabetic nephropathy is one of the most serious complications of this disorder. The polymorphisms in the apolipoprotein A5 (ApoA5) gene are strongly related to hypertriglyceridemia and are considered a predisposing factor for diabetic nephropathy. The current study proposed to examine the association of APOA5-S19W polymorphism with serum lipids levels in patients with type 2 diabetic nephropathy in Mazandaran province...

OBJECTIVES: Metabolic syndrome (MS) is a collection of metabolic disorders including hyperglycemia, hypertension and dyslipidemia. The outcome of metabolic syndrome depends on structural changes in heart like increased left atrial size or increased left ventricular mass. This study was done to determine the echocardiography abnormalities in metabolic syndrome. METHODS: After obtaining informed consent, 75 subjects with metabolic syndrome and 75 controls were included in the study...

BACKGROUND: There has been several discussion and debates regarding the possible setremental influence of elevated serum progesterone (SP) on the day of human chorionic gonadotropin (hCG) administration.

METHODS: In this prospective cohort study, women under ovulation induction through IVF-ICSI using the GnRH-antagonist protocol were studied...

OBJECTIVES: Type 2 diabetes (T2D) is known to be associated with chronic inflammation, but the inflammatory regulators/markers are not exactly defined and the link between them remains undetermined. The objective of this study is to identify these markers by testing traditional (IL6 & IL8) and non-traditional (TREM1 & uPAR) inflammatory markers. METHODS: Data and blood samples were obtained from 114 T2D and 74 non-diabetic Kuwaiti subjects attending health facilities in Kuwait...

OBJECTIVES: MicroRNA expression disruptions play an important function in the expansion of gastric cancer. Previous investigation has indicated that miR-372-5p doing as an oncogene in several malignancies. CDX1 and CDX2, as target genes of miR-372-5p, play the role of tumor suppressors and oncogenes in gastric cancer cells, respectively. The current investigation explored the effects of miR-372-5p regulation on CDX2 and CDX1 in AGS cell lines and studied their molecular mechanism. METHODS: hsa-miR-372-5p miRCURY LNA miRNA Inhibitors and Mimic were transfected into AGS cell line...

Major Depressive Disorder (MDD) is a mood disorder classified as a persistent depressive mood and loss of interest lasting for more than two weeks and accompanied by a list of symptoms outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) diagnostic criteria. MDD affects approximately 264 million people worldwide and is the most prevailing form of neuropsychiatric disorder. Owing to the probable hypothesized pathophysiology of MDD being an outcome of abnormalities in the amino acid neurotransmitter system, including glutamate (the primary excitatory neurotransmitter) and γ -aminobutyric acid (GABA), SAGE-217 (Zuranolone) is being evaluated as a possible therapeutic treatment for MDD...

DNA methylation is the most important epigenetic element that activates the inhibition of gene transcription and is included in the pathogenesis of all types of malignancies. Remarkably, the effectors of DNA methylation are DNMTs (DNA methyltransferases) that catalyze de novo or keep methylation of hemimethylated DNA after the DNA replication process. DNA methylation structures in cancer are altered, with three procedures by which DNA methylation helps cancer development which are including direct mutagenesis, hypomethylation of the cancer genome, and also focal hypermethylation of the promoters of TSGs (tumor suppressor genes)...

OBJECTIVES: Metabolic syndrome (MetS) may cause premature development of some diseases. PON1 genes may be involved in the pathogenesis of MetS. The aim of study was to evaluate the association between Q192R and L55M gene polymorphisms and its enzyme activity with the MetS components in subjects with and without MetS. METHODS: Polymerase Chain Reaction and Restriction Fragment Length Polymorphism analysis were performed to determine polymorphisms of the paraoxonase1 gene in subjects with and without metabolic syndrome...

The study analyzed changes in observed cervical mucus discharge, various hormones in first morning urine, and serum progesterone...

OBJECTIVES: Androgen receptor (AR) play a key role in the onset and progression of prostate cancer. Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound and the active ingredient in green tea, which is involved in modulating gene expression through epigenetic alterations. Previous studies have shown that EGCG at low concentrations reduces the expression of AR and prostate-specific antigen (PSA) in the LNCaP cell line of prostate cancer. In this study, the effect of higher EGCG concentrations on AR and PSA expression in LNCaP prostate cancer cell line was investigated...
