Objective Gestational diabetes mellitus (GDM) is closely related to obesity, adipose tissue, and adipokines. Adiponectin-homologous adipokines with anti-inflammatory properties, including C1q/TNF-related protein 3 (CTRP3) and CTRP9, regulate glucose and lipid metabolism, which was measured in pregnant women with GDM with the aim to assess their circulating levels and their relation with inflammatory cytokines and other biochemical data. Methods Serum levels of CTRP3, CTRP9, adiponectin, tumor necrosis factor (TNF)-α, and interleukin (IL)-6 were measured in 43 subjects with GDM and 42 healthy controls by enzyme-linked immunosorbent assay. Results Serum levels of adiponectin and CTRP3 were lower in GDM subjects than in controls, whereas CTRP9, TNF-α, and IL-6 showed higher concentrations in subjects with GDM than in controls. In the subjects with GDM, there was a significant association of CTRP3 with homeostasis model assessment of insulin resistance (HOMA-IR), body mass index, and triglycerides, whereas CTRP9 is associated with TNF-α and HOMA-IR. Conclusion The differences in the assessed levels of CTRP3 and CTRP9 suggest a possible relation with the pathogenesis of GDM, in particular insulin resistance, which showed significant association with both adipokines.
The primary metabolize of chlorpyrifos (CPF) is in the liver tissue, which it can cause oxidative damage and apoptosis in liver cells. The use of exercise with antioxidant supplements could have a protective effects in the liver tissue especially by improve mitochondria function. The aim of the present study was to investigate the protective effect of aerobic exercise and eugenol (Eu) supplementation on destructive effects of CPF in liver tissue. Sixty-four adult male albino rats were randomly divided into eight groups (eight rats in each group). Four experimental groups received intraperitoneal injection of either 3.0 mg/kg body weight CPF in dimethyl sulfoxide for six consecutive weeks. Aerobic exercise was performed 5 days per week over 4 weeks for exercise groups. Finally, the animals were sacrificed for the histomorphometric analysis and biochemical measurement in the liver tissue. The result of this study show that consumption of CPF alone, caused collagen deposition, increased apoptosis, tumor necrosis factor α, malondialdehyde, and decreased catalase, superoxide dismutase, acetylcholinesterase (AChE) compared to control and exercise groups
BackgroundThe association between breast cancer (BC) and different indices of dietary fats has not been well-studied. Thus, this study aimed to investigate the association between BC and dietary fat quality (DFQ) indices in Iranian women.MethodsThis case–control study was conducted on 120 women with breast cancer and 240 healthy women in Tehran, Iran. Food Frequency Questionnaire and nutritionist IV software were used to assess the intake of dietary fats and to calculate the DFQ indices.ResultsThe patients with BC had a higher total fat (TF) (P < 0.01) and a lower ratio of polyunsaturated fatty acids (PUFAs) omega-3 to PUFAs omega-6 (ω-3/ω-6) compared with the controls (P < 0.001). TF had a significant association with BC risk (OR: 1.16; 95% CI: 1.01–1.33, P < 0.001). No significant association was found between BC and PUFA/saturated fatty acid ratio or the ω-3/ω-6 ratio.ConclusionThe patients with BC had a lower ω-3/ω-6 ratio and a higher total dietary fat intake than the healthy women. Total dietary fat intake was also directly associated with the risk of BC. Thus, low-fat diets may have beneficial effects for BC prevention. Further longitudinal studies are warranted.
Abstract. Recent studies have reported that dietary antioxidants can influence the risk of breast cancer (BC). Therefore, this study aimed to investigate the association of dietary antioxidant index (DAI) with BC among Iranian women. This case-control study was conducted on 180 women with breast cancer and 360 healthy women who were referred to the cancer clinic of Shohadaye Tajrish Hospital in Tehran, Iran. A 168-item validated food frequency questionnaire (FFQ) was used to assess dietary intake. The DAI score was calculated based on the intake of antioxidant vitamins and minerals derived from the FFQ. The control group had a significantly higher intake of vitamin D (1.79±1.56 vs. 1.05±0.84 μg/d; P=0.01) and lower intake of calorie (2315±1066 vs. 2737±925 kcal/d; P=0.01), carbohydrate (311±170 vs. 402±124 g/d; P=0.01), iron (15.4±12.1 vs. 19.7±6.4 mg/d; P=0.01), thiamine (1.5±0.7 vs. 2.3±0.9 mg/d; P=0.01), niacin (18.2±9.2 vs. 24.3±7.9 mg/d; P=0.01), folic acid (465±308.7 vs. 673±205.2 μg/d; P=0.01), and selenium (82.6±41.7 vs. 98.7±40.8 μg/d; P=0.01) compared to the case group. No significant association was found between DAI with breast cancer after adjustments for age. DAI had a negative association with breast cancer after additional adjustments for BMI, the number of pregnancies, duration of breastfeeding, menopause age, and total energy intake (OR: 0.91, 95% CI: 0.90–.93, and all P<0.001). The present study identified a negative association between DAI and the risk of BC, indicating the importance of antioxidants in preventing BC. Longitudinal studies should be conducted to confirm this association.
