Calorie Restriction (CR) is known as one of the most effective life-extending interventions. Therefore researchers are looking for other interventions or drugs to mimic the mentioned effects. Time-restricted feeding (TRF) has recently gained more attention recently as one of the CR mimetics.

Background: Calorie restriction (CR) is known as a nutritional gold standard for life extension and different studies have shown that insulin-like growth factor (IGF1) reduction through CR may be involved in CR's anti-aging effects. Besides, time-restricted-feeding (TRF) is also highlighted due to more feasibility and positive health effects. We designed this study to compare the effects of CR and TRF on IGF1 and other metabolic parameters.

Diabetes mellitus is the most common metabolic disorder worldwide. This study examined the effect of turmeric supplementation on glycemic status, lipid profile, hs-CRP and total antioxidant capacity in hyperlipidemic type 2 diabetic patients. In this double-blind, randomized clinical trial, 80 hyperlipidemic type 2 diabetic patients were divided into turmeric (2,100 mg powdered rhizome of turmeric daily) and placebo groups for 8 weeks.

According to the recent studies, vitamin D deficiency has been correlated with progress in type 2 Diabetes and Metabolic Syndrome. The aim of this study was to assess the effect of vitamin D supplementation on glucose and lipid profiles, blood pressure, and biomarkers of liver and kidney in type 2 diabetic patients. In this Double blinded randomized clinical trial, 90 patients with type 2 diabetes and serum 25-Hydroxy vitamin D levels of less than 30 ng/ml recruited from "Besat Diabetes Clinic" in Rasht, North of Iran.

Background: Ferrous sulfate is the most used supplement for treating anemia, but it can result in unfavorable side effects. Nowadays, nanotechnology is used as a way to increase bioavailability and decrease the side effects of drugs and nutrients. This study investigates the effects of nanoparticles containing iron on blood and inflammatory markers in comparison to ferrous sulfate in anemic rats.

Purpose. The association between serum lipids and bone mineral density (BMD) has been investigated previously but, up to now, these relationships have not yet been described in spinal cord injury (SCI). We tried to assess the correlation between serum triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) and BMD in male subjects with SCI.

Context: Omega-3 fatty acids have been recently proposed to induce neural improvement in patients with spinal cord injury (SCI) while affecting some hormones including leptin and adiponectin.

Objectives: We tried to evaluate the effect of omega-3 fatty acids on circulatory concentrations of leptin and adiponectin among these patients.

Design: This study is a double-blinded randomized clinical trial with intervention duration of 14 months.

Background Context: Previously, the associations between leptin and adiponectin levels with bone mineral density (BMD) have been reported in different populations, and occasionally, controversial results have been demonstrated. Until now, these relationships in spinal cord-injured individuals have not yet been described.

Purpose: We tried to investigate the correlation between leptin and adiponectin concentrations in plasma and BMD in Iranian patients with spinal cord injury (SCI).

Objectives: We described the associations between demographic and injury-related factors on bone mineral density (BMD) of the spine and the hip among adult patients with chronic spinal cord injury (SCI).

Design: BMD in spinal and femoral bone sites were assessed. Multivariate analysis was performed to evaluate the relationship between anthropometric and injury-related factors with BMD.

Background Context: Bone loss after spinal cord injury (SCI) occurs because of pathologic changes in osteoblastic and osteoclastic activities due to mechanical unloading. Some biochemical changes in bone metabolism after SCI are described before that were related to bone mineral loss.

Purpose: Our purpose was to determine bone markers' changes and related effective factors in patients with chronic traumatic SCI.

Persons with spinal cord injury (SCI) have a high prevalence of abnormalities in carbohydrate and lipid metabolism. These abnormalities cause adverse coronary heart disease (CHD) in patients with SCI. In this study, we performed a detailed analysis of the level-specific cardiometabolic risk factors in individuals with SCI and analyzed the association of injury level on these risk factors.

Background: Clinical studies have reported that osteoporosis after spinal cord injury (SCI) can be the inflammation-induced base condition and n-3 polyunsaturated fatty acids (PUFAs) suppress the production of pro-inflammatory cytokines. This study documents the effects of n-3 PUFAs on cytokines in a group of patients after chronic SCI.

Methods: This double-blind, placebo- controlled trial was designed in 82 (69 males and 13 females) osteoporotic patients with SCI for 4 months.
