Introduction : Bilateral salpingo-oophorectomy (BSO) is a risk factor for osteoporosis. Previous studies have reported an association between genetic polymorphisms and the risk of developing osteoporosis. However, the relationship between osteoporosis and genetic polymorphisms in Japanese women treated with BSO is not well understood. To improve the quality of life for post-BSO patients, it is important to determine the genetic factors that influence their risk for osteoporosis. The aim of this study was to investigate the association between gene variations of estrogen metabolism-related gene

Introduction: Breastmilk is recognised as the best infant nutrition, but Exclusive Breastfeeding (EBF) rates remain as low as 63.7% in India and 48% worldwide. One barrier is the development of Musculoskeletal Disorders (MSDs) in postpartum mothers due to a lack of education on proper breastfeeding posture. These factors can impact the quality of the infant’s latch, resulting in early cessation of breastfeeding. Aim: This study aimed to assess the impact of ergonomic breastfeeding on the risk of developing MSD in lactating mothers and infant latch quality. Materials and Methods: The present qu

OBJECTIVES Although the effect of physical activity (PA) on the incidence of atrial fibrillation (AF) has been studied, contradictory results have been reported. Such discrepancies may reflect the different effects of various types of PA upon AF, as well as gender interactions. Therefore, we aimed to evaluate the associations of PA types (total, moderate/vigorous, and intentional), as well as walking pace, with AF risk in men and women. METHODS Using the Multi-Ethnic Study of Atherosclerosis Typical Week Physical Activity Survey, 3 PA measures and walking pace were calculated among 6,487 men a

We studied the associations between selenium exposure and prostate diseases such as prostate cancer (PCa) and benign prostatic hyperplasia (BPH), and estimated the optimal range of selenium concentrations that may be needed to prevent these diseases among Nigerian men. Blood and urine samples from men with histologically diagnosed PCa (n = 90), BPH (n = 97), and controls (n = 98) were analyzed for trace elements, including selenium. The associations bet

Abstract Background TRAIL plays an important role in host immunosurveillance against tumor progression, as it induces apoptosis of tumor cells but not normal cells, and thus has great therapeutic potential for cancer treatment. TRAIL binds to two cell-death-inducing (DR4 and DR5) and two decoy (DcR1, and DcR2) receptors. Here, we compare the expression levels of TRAIL and its receptors in normal oral mucosa (NOM), oral premalignancies (OPM), and primary and metastatic oral squamous cell carcinomas (OSCC) in order to characterize the changes in their expression patterns during OSCC initiation a
