Probiotics are living microorganisms increasingly used to treat or modulate different diseases or disorders because of their benefits and also low adverse reaction, and their positive and protective effects on various cells and tissues have been reported. The mechanisms by which probiotics exert their beneficial effects in different cells and tissues were investigated, and autophagy is one of the main mechanisms to induce their positive effects. Autophagy is a conserved process that occurs in all eukaryotic cells and plays an essential role in homeostasis and cell survival by degrading damaged and dysfunctional intracellular organelles.

Objectives: To review non-surgical prevention strategies in women with hereditary breast and ovarian cancer syndromes.

Content: Women with a g or mutations face a high cumulative breast and ovarian cancer risk. While bilateral mastectomy (PBM) and bilateral salpingo-oophrectomy (PBSO) profoundly reduce the respective cancer risks, they are also associated with considerable side effects.

Background: FGF23 controls serum l,25(OH)D levels and phosphate homeostasis. This study evaluates the effects of ferritin on intact PTH, FGF23, and l,25(OH)D in patients with major thalassemia. It also evaluates FGF23 changes in patients with hypoparathyroidism to clarify the interaction between FGF23 and PTH in the absence of proper PTH functioning in human.

Unlabelled: Despite the significant improvements in the management of thalassemia, there are growing concerns regarding their long-term complications. We showed that low bone mass is one of the most prevalent complications among these patients. Insufficient physical activity and hypogonadism are the main possible associated factors followed by DM and insufficient sun exposure.

Background And Study Aim: Chronic use of proton-pump inhibitors (PPIs) has become a mainstay of therapy in common gastrointestinal diseases. A causal relationship between chronic PPI use and development of osteoporosis remains unproven. The aim of this study was to determine whether PPI users are more likely to develop alterations in bone density.

Unlabelled: Bone health evaluation in children requires an appropriate reference database. We have shown higher curves for spine aBMD in Iranian subjects than Americans, but lower curves for femoral neck and total body. These results can be used as reference values to assist Iranian clinicians in interpreting and monitoring bone densitometry results.

Background: Low serum vitamin D has been associated with metabolic syndrome and Non-alcoholic fatty liver disease (NAFLD). This study aimed to investigate the impact of vitamin D supplementation in treatment of patients with NAFLD.

Methods: In a double blind, randomized, placebo controlled trial patients with NAFLD were randomized to receive one weekly pearl of placebo, 50,000 U vitamin D3 (cholecalciferol) pearl per week and 0.

Background: Wnt signalling/LRP5 is involved in adipogenesis by down-regulating adipogenic transcription factors. Therefore polymorphisms in components of this pathway may lead to metabolic disorders.

Aim: This study tested the impact of LRP5 polymorphism on lipid profile in Iranian children.

The genetic epidemiology of variation in bone mineral density (BMD) and osteoporosis is not well studied in Iranian populations and needs more research. We report a candidate gene association study of BMD variation in a healthy cross-sectional study of 501 males and females sampled from the Iranian Multi-Centre Osteoporosis Study, Shiraz, Iran. We selected to study the association with 21 single nucleotide polymorphisms (SNPs) located in the 7 candidate genes , and .

Unlabelled: Acute leukemia is the most common malignancy in children. We showed that low bone mass is prevalent among children with leukemia, especially in femur. Serum calcium, exercise, chemotherapy protocol, and radiotherapy are the main contributing factors.

Objectives: This study was conducted to assess bone mineral density (BMD) and bone mineral content (BMC) of patients with hemoglobin H (HbH) disease.

Methods: BMD and BMC were measured by dual energy X-ray absorptiometry of the lumbar spines and femur neck in 21 patients with Hb H disease over the age of 10 years. An association of BMD with sex, age, hemoglobin, calcium, phosphorus, and serum ferritin level was also evaluated.

Failure to achieve optimal bone mass in childhood is the primary cause of decreased adult bone mineral density (BMD) and increased bone fragility in later life. Activating and inactivating LRP5 gene mutations has been associated with extreme bone-related phenotypes. Our aim was to investigate the role of LRP5 polymorphism on BMD, mineral biochemical parameters, and body composition in Iranian children.

Aim Of The Study: Thyroid dysfunction and autoimmunity are common problems in women of child-bearing age. It could be associated with pregnancy morbidities in the mother and fetus. Due to lack of sufficient data about the prevalence of thyroid autoimmunity in pregnant women in Iran, and controversies about its complications on pregnancy outcomes, this study was conducted.

Aim: This study aimed to investigate the prevalence, metabolic risk factors, and thyroid dysfunction among a healthy urban population.

Methods: In a cross-sectional study, the patients were evaluated for nonalcoholic fatty liver disease (NAFLD) using ultrasonography. The participants' characteristics such as age, sex, weight, height, body mass index (BMI), waist circumference, hip circumference, waist-to-hip ratio, systolic and diastolic blood pressure, and history of diabetes, ischemic heart disease (IHD), hypertension, and hyperlipidemia were recorded using a data gathering form.

Background: Killer cell immunoglobulin-like receptors (KIR) are expressed on NK cells and a subset of T cells. The variable KIR receptors along with their ligands, HLA class I, influence risk for autoimmune and malignant diseases.

Objective: To investigate the KIR gene profiles in relation to susceptibility to Graves' disease in patients with ophthalmopathy.

Background: Vanadium compounds are able to reduce blood glucose in experimentally- induced diabetic rats and type 2 diabetic patients, but data about their long- term safety and efficacy in diabetic patients are scarce.

Methods: Fourteen type 1 diabetic patients received oral vanadyl sulfate (50 - 100 mg TID) for a period of 30 months. Fasting blood sugar (FBS), lipid levels, hematologic, and biochemical parameters were measured before and periodically during the treatment.

Unlabelled: We provide the first reference values for bone mineral content and bone mineral density according to age and sex in Iranian children and adolescents. The prevalence of hypovitaminosis D was high, and levels of physical activity were low in our sample. Multiple regression analyses showed age, BMI, and Tanner stage to be the main indicators of bone mineral apparent density.
