Unexpected poor ovarian response (UPOR) occurs when nine or fewer oocytes are retrieved from a young patient with normal ovarian reserve. Bone morphogenetic protein15 (BMP15) and growth differentiation factor 9 (GDF9) are two oocyte-specific factors with pivotal role in folliculogenesis. The aim of this study was to assess the relation between BMP15 and GDF9 variants with UPOR.

Background: Genetic factors play a substantial role in acute myeloid leukemia (AML) etiology. Overexpression of the mouse double minute 2 (MDM2) gene has been explored in many tumors. However, the role of MDM2 -309T>G (rs2279744) polymorphism in AML remains unclear.

Risk factors for ovarian cancer include a number of genetic variants as well as endometriosis. The - system is one of the apoptotic pathways that play an essential role in the apoptotic process within the endometrium. Here, we evaluate the correlation between - polymorphisms with the risk of endometriosis in Iranian patients and healthy controls.

Article Synopsis
  • Telomere length is a marker of cellular aging and has been linked to inflammation and oxidative stress, with emerging evidence suggesting air pollution impacts TL.
  • A systematic review and meta-analysis of studies up to July 2018 were conducted to explore the relationship between air pollution and TL in adults, assessing the quality of 19 identified studies.
  • Results indicated that long-term exposure to particulate matter (PM) was inversely related to TL, whereas short-term PM exposure and exposure to Polychlorinated Biphenyls (PCBs) showed a positive association with TL, suggesting varying impacts depending on the duration of exposure.

The aim of this study was to investigate spatial variation and health risk of the exposure to PM (particulate matter with a diameter of 2.5 µm or less) and PM (particulate matter with a diameter of 10 µm or less) in Sabzevar, Iran. PM and PM were measured during three campaigns from April to November 2017, in 26 sampling points.

The aim of this study was to assess the potential health risk of exposure to polycyclic aromatic hydrocarbons (PAHs) at home and kindergarten for pre-school children. The urine samples were taken from 200 pre-school children aged 5-7 years and analyzed for 1-OHP as a biomarker of PAHs. Mixed effect models were applied to investigate the association between effective environmental parameters (mode of transport, distance to major roads, traffic density, greenness, tobacco exposure, home ventilation, and grill foods) and urinary 1-OHP levels.

Background: Genetic factors are believed to play an important role in the etiology of polycystic ovarian syndrome (PCOS) which is the most common endocrinological disorder of women in their reproductive age. Androgen metabolism is impaired in PCOS and, thus, gene which is involved in this pathway can be a candidate gene. Previous studies have shown a relationship between single nucleotide polymorphism (SNP) of in hyperandrogenism and PCOS in some racial groups.

Introduction It has been hypothesized that mental disorders including depression and anxiety can affect immune responses. The study was done to evaluate the relation between depression and anxiety and expression levels of CD36, CD68, and CD9 on peripheral blood monocytes of chronic hepatitis B (CHB) patients. Methods Sixty CHB patients were selected with various ranges of depression and anxiety.
