       This study was planned to investigate the effects of supplementation of cinnamon on fasting blood glucose levels and lipid profiles among type2 diabetic patients. 60 subjects with type 2 diabetes from both sexes (30 males and 30 females) were allocated to the intervention and control groups (30 individuals per group). The doses of 1.5 g of cinnamon were equally administered orally in the form of cinnamon powder into 500 mg per capsule with breakfast, lunch, and dinner for 60 days. Control group received capsules of containing placebo. Blood samples were obtained on the beginning day of the experiment and at the end of 60 days. The fasting blood glucose levels and lipid profiles including total cholesterol, LDL-C, HDL-C and triglycerides of types 2 subjects were measured. Fasting blood glucose levels and lipid profiles in intervention group were significantly lower than control group (

    One of the common issues that occur after total knee replacement surgery is the aseptic loosening. The problem usually occurs after about 15 years from the surgery. The destructive effects of residual particles due to wear, the stress shielding effect, and micro-movements are the causative factors for this type of loosening. In this research, using the advantages of functionally graded biomaterials (FGBM), it is tried to design a prosthetic system that can reduce the above-mentioned effects. For this purpose, the materials used in the most important part of the prosthesis system, i.e., the femoral part are redesigned so that the bioactivity between the prosthesis and bone, and the stress applied to the adjacent tissues increase simultaneously. In addition, to reduce the effect of wear at contact areas, wear-resistant biocompatible ceramics such as alumina and zirconia are used. The value of stress at the bone-prosthesis interface and adjacent tissues is the most important parameters. Two types of three-phase ceramic-based FGBMs are recommended. The prosthesis with three-phase hydroxyapatite-titanium-zirconia has increased the average stress in the bone tissues around high-risk areas up to 71.8% with respect to a commonly used Cr-Co prosthesis. The result for the prosthesis with three-phase hydroxyapatite-titanium-alumina is up to 65%, respectively. At bone-prosthesis interfaces, an increase of 92% in the stress for both zirconia-based and alumina-based is seen. Briefly, the recommended FGBMs can improve the bone-prosthesis performance in all desired indices

    Background: Cyclophosphamide (CP) is an anti-neoplastic alkylating agent that is extensively used in different chemotherapy regimens. Adverse effects on the reproductive system, especially spermatogenesis, are one of the most important side effects of this drug. It is medically essential to use complementary and alternative drugs. Herbal drugs have long been used as a complementary treatment. Our purpose was to study the effect of hydroalcoholic Allium atroviolaceum L. extract on spermatogenesis in CP-treated mice. Results: CP affected a significant decrease in sperm count, motility, viability, and morphology. Sperm count was significantly higher in the all extract groups than in the group of control (p<0.001) and CP group (p<0.001, p<0.01). Sperm motility was significantly greater in the extract (100 and 200mg/kg) groups than in the group of control (p<0.05 and <0.001). Sperm immotility and rotational movement were significantly higher in the CP group than in the CP+extract groups (p<0.001). The sperm viability was significantly greater in the CP+extract (200mg/kg) group than in the CP group (p<0.001). The number of headless sperm, sperm with initial tail, with coiled tail, and sperm with curved body, was significantly lower in the CP+extract (200mg/kg) group than in the CP group (p<0.001). Conclusion: A. atroviolaceum extract treatment significantly improved CP-induced reproductive toxicity

    Background: The most important side effects of Cyclophosphamide, as an anticancer broad-spectrum drug, are the negative effects on the reproduction and fertility because of oxidative stress. Considering the antioxidant properties of medicinal plants, especially those of the Allium genus, this paper studied the effect of hydroalcoholic extract of Allium atroviolaceum L. on the pathology of testicular tissue in CP-treated mice. Methods: Groups of this experimental study consisted of normal saline recipients; three groups receiving A. atroviolaceum extract at 50, 100, 200 mg/kg; three groups receiving A. atroviolaceum extract at 50, 100, and 200 mg/g and 6.6 mg/kg of Cyclophosphamide; and a group given Cyclophosphamide at 1.6 mg/kg. All injections were performed intraperitoneally. After 30 days, the testicular histological profile as well as the number of spermatozoa, the number of primary and round spermatocytes, and the number of spermatogonia were investigated. Results: Cyclophosphamide treatment significantly reduced the lumen diameter, the seminiferous tubule diameter, the epithelial thickness, as well as decreased the quantity of spermatozoa and round and primary spermatocytes compared to the control group. Cyclophosphamide groups treated with A. atroviolaceum extract at 50, 100 and 200 mg/kg in a significant manner improved these variables (P < 0.001). Conclusion: A. atroviolaceum extract can significantly improve Cyclophosphamide-induced toxicity and pathological process on testicular tissue. It seems that this plant, with high antioxidant capacity, can be considered a complementary therapy for Cyclophosphamide to prevent undesirable effects on the reproductive system.

    Background Critical inter-provincial differences within Iran in the pattern of non-communicable diseases (NCDs) and difficulties inherent to identifying prevention methods to reduce mortality from NCDs have challenged the implementation of the provincial health system plan. The Shahrekord Cohort Study (SCS) was designed to address these gaps in Chaharmahal and Bakhtiari, a province of high altitude in the southwest of Iran, characterized by its large Bakhtiari population, along with Fars and Turk ethnicity groups. Methods This ongoing cohort, a prospective, large-scale longitudinal study, includes a unique, rich biobank and was conducted for the first time in Chaharmahal and Bakhtiari Province in Iran. SCS is a part of the PERSIAN (Prospective Epidemiological Research Studies in IrAN) cohort. The study began in 2015, recruited 10075 participants (52.8% female, 47.2% male) from both urban (n=7034) and rural (n=3041) areas, and participants will be annually followed up for at least 15 years. A cross-sectional analysis was conducted using baseline data from the SCS, using descriptive statistics and logistic regression. Data analysis was performed using Stata software. Results The prevalence of NCDs was 9.8% for type 2 diabetes, 17.1% for hypertension, 11.6% for thyroid disease, 0.2% for multiple sclerosis and 5.7, 0.9 and 1.3% for ischemic heart disease, stroke and myocardial infarction, respectively. The prevalence of multimorbidity (>= 2 NCDs) was higher in women (39.1%) than men (24.9%). The means (standard deviations) of age, BMI, systolic blood pressure and fasting blood glucose were 49.5 (9) years, 27.6 (4.6) kg/m(2), 115.4 (17.3) mmHg and 96.7 (27.3) mg/dL, respectively. Logistic regression models showed that older age, female gender, living in an urban area, non-native ethnicity, high wealth index, unemployment, obesity, low physical activity, hypertriglyceridemia, high fasting blood sugar, alkaline urine pH and high systolic and diastolic blood pressure were associated with increased prevalence of NCDs. Conclusions The SCS provides a platform for epidemiological studies that will be useful to better control NCDs in the southwest of Iran and to foster research collaboration. The SCS will be an essential resource for identifying NCD risk factors in this region and designing relevant public health interventions

    The Power of Social Theory: The Anti-Colonial Discursive Framework

    This paper introduces the anti-colonial discourse as a guiding framework for forming alliances and partnerships among anti-oppression activists in the academia and the larger society. To this end, it builds upon insights from narratives of "indigeneity" and traditions of anti-racism theory and praxis. Thanks to the spaces created by Marxist, feminist, post-colonialist, and deconstructionist struggles, the anti-colonial discourse seeks to reclaim a new independent space strongly interconnected with and heavily interlocked to those other spaces. This paper illustrates the interconnectivities, similarities, and dissimilarities between this new anti-colonial space and the spaces created by those other rich traditions . Its aim is to envision a common zone of resistance in which the oppressed and marginalized groups are enabled to form alliances in resisting various colonial tendencies

    ABSTRACT Oxidative stress is induced by a wide range of environmental factors including heavy metals stress such as Cadmium. Therefore, antioxidant resistance mechanisms may provide a strategy to enhance metal tolerance, and processes of antioxidant responses to metal stress must be clearly understood. And also identification of tolerant cultivars and study of tolerance mechanisms to heavy metal stress is necessary in order to evaluate Cadmium stress effect on super oxide dismutase, catalase and glutathione peroxydase activity, a pot experiment was done in the form of factorial in randomized complete block design (RCBD) in research greenhouse of Islamic Azad University, college of agriculture and natural resources branch of karaj. In this experiment 6 bean seeds genotypes grew in greenhouse conditions in the soil consist of CdCl 2 with concentration of 0, 45, 90 mg/kg. The results of analysis of variance indicated that effect of Cd stress on above traits in different bean genotypes were significant. Thus, amount of SOD, CAT and GPX enzymes activities, in the highest level of Cd toxicity, were increased 146.2%, 96.2% and 92%, respectively in compared to control that these results can be the effects of tolerance mechanisms of plants against Cd stress. Mean comparison showed that Emerson and G-01437 genotypes have the most activity in the highest level of Cd toxicity by comparison with control. According to received results, increase in antioxidant activity in special genotypes is referred to the index of tolerance to Cadmium stress
