We investigated how myofibrillar protein synthesis (MPS) and muscle anabolic signalling were affected by resistance exercise at 20-90% of 1 repetition maximum (1 RM) in two groups (25 each) post-absorptive, healthy, young (24 +/- 6 years) old (70 5 men with identical body mass indices 2 kg m(-2)). hypothesized that, response to exercise, molecule phosphorylation MPS would be modified a dose-dependant fashion, but lesser extent older men. Vastus lateralis was sampled before, immediately...

Transgenic Brassica napus plants overexpressing AtNHX1, a vacuolar Na + /H antiport from Arabidopsis thaliana, were able to grow, flower, and produce seeds in the presence of 200 mM sodium chloride. Although transgenic grown high salinity accumulated up 6% their dry weight, growth these was only marginally affected by salt concentration. Moreover, seed yields oil quality not soil. Our results demonstrate potential use for agricultural saline soils. findings, showing that modification single...

Opioids are a group of analgesic agents commonly used in clinical practice. There three classical opioid receptors (DOP, KOP and MOP), while the novel NOP receptor is considered to be non-opioid branch family. can act at these as agonists, antagonists or partial agonists. Opioid agonists bind G-protein coupled cause cellular hyperpolarisation. Most clinically relevant analgesics MOP central peripheral nervous system an agonist manner elicit analgesia. may also classified according their mode...

Temporal hypometabolism on fluorodeoxyglucose positron emission tomography (FDG-PET) is a common finding in patients with drug-resistant temporal lobe epilepsy (TLE). The pathophysiology underlying the hypometabolism, including whether it reflects primary epileptogenic process, or occurs later as result of limbic atrophy chronic seizures, remains unknown. This study aimed to investigate ontologic relationship among atrophy, histological changes, and rats.Serial vivo imaging FDG-PET...
