Background and Objective: Fluctuation in the homeostasis system is one of the main causes of heart attacks. There are contradectry reports regarding the effect of regular exercise, particularly resistance training on hemostasis indeces. This study was done to determine the effect of 8 weeks of resistance training on hemostasis indeces and lipid profile in adult men. Methods: In this clinical trail study, 16 adult men were randomly divided into interventional and control groups. Subjects in interventional group participated in a resistance training program including a period 3 days a week for 8 weeks session. Body mass index, level of fibrinogen, protrombin time (PT), partial thromboplastin time (PTT), platelet count, D-dimer fibrinolytic factor, Cholesterol, Triglyceride, HDL and LDL were measured for each subject. Results: After 8 weeks of resistance training, the level of fibrinogen, PT, PTT and platelets count were significantly reduced and D-dimer fibrinolytic factor increased in interventional group in compared to controls (P<0.05). Serum level of Cholesterol, Triglyceride, HDL and LDL had no significant change in interventional group in comparsion with the controls. Conclusion: Resistance training reduces hemostasis indeces in adult men.

Background and Objective: Nano-sized particles at scale of 1 to 100 nm, called nanoparticles. In addition, the composition and structure of materials is also one of the factors influencing the material properties. With the advent of nanotechnology and due to increasing antimicrobial properties of nanoscale silver it can also be used in the fight against various human pathogens. This study was carried out to evaluate the antibacterial effect of silver nanoparticles synthesized by green method against the standard strains Escherichia coli k12 and Escherichia coli 25922. Methods: In this descriptive study, silver nanoparticles were synthesized using Prosopis farcta seed exudates and analyzed by UV visible spectrophotometer, X-ray diffraction and transmission electron microscopy. Antibacterial effect of silver nanoparticles was evaluated using broth macro-dilution method. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of silver nanoparticles was determined on the standard strains of Escherichia coli k12 and Escherichia coli ATCC 25922. Results: Transmission electron microscopy showed nanoparticles with diameters in the range between 5-35 nm with a maximum frequency range in 20-25 nm. The minimum inhibitory concentrations of bacteria, of E. coli k12 and E. coli 25922 respectively, were 1.56 and 0.39 µg/ml (ppm) and minimum bactericidal concentrations of 3.12 and 0.78 µg/ml wiring (ppm). Conclusion: Biological synthesis using P. farcta seed is a inexpensive, method and require no energy. Due to the strong antibacterial activity of silver nanoparticles, can be a suitable alternative for disinfectants, disinfection and control of pathogens.

Background and Objective: Exercise in cardiac patients after coronary artery bypass grafting (CABG) improves cardiovascular function by increasing the capillary density of the myocardium. Platelet-derived growth factor and stromal cell-derived factor-1 play an important role in angiogenesis and cell proliferation and differentiation. This study was performed to determine the effect of eight weeks of combined training on plasma levels of Platelet-derived growth factor (PDGF) and stromal cell-derived factor-1 (SDF1) in CABG patients.
Methods: In this clinical trial study, 24 patients who underwent coronary artery bypass grafting operation were selected using convenience and purposeful sampling method and randomly divided into two combined training and control groups. Subjects in combined training group were received aerobic and resistance training protocols for eight weeks, three sessions per week. Before and after training program, body composition assessments and blood sampling were performed to measure Platelet-derived growth factor (PDGF) and stromal cell-derived factor-1 (SDF1). ELISA method was used to measure PDGF and SDF1.
Results: The level of PDGF was significantly increased in intervention group in compared to control group (P<0.05). Although the level of SDF1 in the intervention group increased in intervention group in compared to control group; but this increase level of SDF1 was not significant.
Conclusion: This study showed that the eight weeks of combined rehabilitation training can promote desirable physiological adaptations in cardiovascular health by increasing the plasma levels of PDGF.
