16. Resistance to Fluoroquinolones in Escherichia coli: Prevention, Genetics and Fitness Costs
Abstract : Antibiotic-resistant bacteria are increasingly a major healthcare problem but very few new classes of antibiotics have been discovered or launched in recent decades. Approaches to dealing with the problem include learning how bacteria evolve to resistance and improving dosing regimens with current antibiotics so as to reduce the selection of resistant bacteria.

17. A 3-year lifestyle intervention in primary health care : effects on physical activity, cardiovascular risk factors, quality of life and cost-effectiveness
Abstract : Background: A sedentary lifestyle diminishes quality of life (QOL) and contributes to increasing prevalence of obesity, diabetes and cardiovascular diseases (CVD), and thus increases the economic burden on health care and society. Expensive and tightly controlled lifestyle interventions reduce cardiovascular risk and onset of diabetes. READ MORE

18. Antibiotic Resistance and Fitness of Escherichia coli in the Infantile Commensal Microbiota
Abstract : Microbial resistance to antibiotics is a growing problem worldwide. Resistance develops not only in microbes which are the targets of the antibiotic treatment, but also in those belonging to the normal microbiota of the treated host. Little is known on the ecological consequences of antibiotic resistance in commensal bacteria. READ MORE

19. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans
Abstract : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.

20. Acute and early chronic responses to resistance exercise using flywheel or weights
Abstract : Resistance exercise using weights typically offers constant external load during coupled shortening (concentric) and lengthening (eccentric) muscle actions in sets of consecutive repetitions until failure. However, the constant external load and the inherent capability of skeletal muscle to produce greater force in the eccentric compared with the concentric action, would infer that most actions are executed with incomplete motor unit involvement.
