Abstract
ABSTRACT
Background and Objectives: Osteoarthritis (OS) is the most common type of arthritis and joint disease, especially in women. Proinflammatory cytokines, biochemical factors, specially matrix metalloproteinases, and reactive oxygen species play important roles in joint destruction in this disease. Therefore, the present study aimed to evaluate level of inflammatory factors and its relationship with clinical symptoms of OS in female patients.
Methods: The study was performed on female patients with knee OS, referring to healthcare centers of Tabriz University of Medical Sciences. After measuring the weight and height of patients, clinical symptoms such as severity of pain and physical performance were evaluated using the Knee Injury and Osteopaedic Outcome Score questionnaire. Serum levels of IL-1β, TNF-α, and hs-CRP in fasting blood samples were measured using ELISA kits and immunoturbidimetric assays.
Results: There was a significant association between level of IL-1β and score of pain. There was no significant relationship between the clinical symptoms and level of other inflammatory factors.
Conclusion: The results of the present study showed that the increase in inflammatory factors is correlated with severity of pain in OS patients.

Abstract
Background and objectives: Blood flow restriction training (BFRT) has gained substantial interest due to the lower required intensity, which may be beneficial for individuals who are not able to lift heavy weights. Therefore, we aimed at evaluating effects of 12 weeks of resistance training with and without blood flow restriction on follistatin (FST) concentrations and physical performance in elderly females.
Methods: Thirty elderly female were randomly assigned into the following groups: resistance training with blood flow restriction (BFRT; n=10), resistance training without blood flow restriction (WBFRT; n=10) and control ( n=10). The resistance training was carried out three session a week for 12 weeks. Serum concentrations of FST, muscular endurance and dynamic balance were assessed at baseline and after the 12week intervention.
Results: Significant main effects of time were observed for FST (p =0.03, η2 = 0.15), muscular endurance (p = 0.00, η2 = 0.59) and dynamic balance (p=0.00, η2 = 0.57). FST [BFRT= 1.4 ng/ml (effect size Cohen’s {d} = -0.8) significantly increased only in BFRT group. However, muscular endurance [BFRT= 95 (d= -4.1) and WBFRT = 32 (d= -0.9)] significantly increased in both intervention groups (P<0.05). In addition, dynamic balance [BFRT= -0.5 seconds (d= 2.2)] significantly increased only in the BFRT group (P<0.05).
Conclusion: BFRT was able to increase FST concentrations. Due to its mechanistic role in muscle mass alterations, elderly females can incorporate our BFRT protocol to improve anabolic conditions for muscular adaptations.

Abstract
Background and objectives: Endurance exercise causes fatigue due to mitochondrial dysfunction and oxidative stress. The present study was designed to investigate the effects of taurine supplementation on lipids peroxidation and antioxidant activity during endurance activities.
Methods: Twenty-four male volunteers aged 27 ± 1.8 years and weighting 74.9 ± 5.9 kg were randomly divided into three groups: taurine supplementation (n=8), placebo (n=8), and control (n=8). The subjects completed a 28-day endurance training protocol. Biochemical parameters such as superoxide dismutase (SOD), glutathione peroxidase (GPX) activities, as well as malondialdehyde (MDA) concentrations (8 hours before the first session and 8 hours after the last session) and maximum rate of oxygen consumption, were measured to evaluate the antioxidant, lipid peroxidation, and VO2 max status respectively. Finally, data were analyzed by SPSS software at a significance level of <0.05.
Results: Taurine supplementation significantly increased SOD (p=0.001) and GPX (p=0.001) but significantly decreased MDA (p=0.001). However, it had no significant effect on the VO2 max.
Conclusion: The results of the present study indicate that taurine has antioxidant effects against endurance exercise-induced oxidant stress and lipid peroxidation.

Abstract
Plasma cell leukemia (PCL) is a rare form of plasma cell dyscrasia with 2 variants: the primary form, which occurs de novo in patients with no previous history of multiple myeloma (MM), and the secondary form, which represents a leukemic transformation in patients with a previously recognized MM. Unlike myeloma, PCL typically follows an aggressive course, and the median age at presentation is usually above 50 years. In this report, we present a case of primary PCL that manifested at 19, an exceptionally rare occurrence.
