the purpose of this study was to investigate the interference effect of concurrent strength and endurance training on maximum strength and vo2max in non-athletes. for this purpose, 34 sedentary healthy men (mean age 22±1.18 years, height 173.61±6.48 cm, and weight 56.13±8.50 kg) voluntarily participated in this study. initially, subjects were randomly assigned to one of four training groups: st...

Endurance exercise is an inexpensive intervention that is thought to provide substantial protection against several age-related pathologies, as well as inducing acute changes to endurance capacity and metabolism. Recently, it has been established that endurance exercise induces conserved alterations in physiological capacity in the invertebrate Drosophila model. If the genetic factors underlyin...

Background: Analysis of many proteins produced during the transition into the stationary phase and under stress conditions (including starvation stress) demonstrated that a number of novel proteins were induced in common to each stress and could be the reason for cross-protection in bacterial cells. It is necessary to investigate the synthesis of these proteins during different stress condition...

the effect of a neuropeptide, the tachykinin on α-amylase, protease and lipase activities in the midgut of american cockroach, periplaneta americana (linnaeus) is evaluated . immunohistochemical reactivities against tachykinin (tachykinin- ir) were detected in the midgut. tachykinin-ir cells in three regions (anterior, median and posterior) of the midgut were counted in normally fed, starved fo...

Intramuscular triglyceride (IMTG) has received considerable attention as a potential mechanism promoting insulin resistance. Endurance-trained athletes have high amounts of IMTG but are insulin sensitive, suggesting IMTG content alone does not change insulin action. Recent data suggest increased muscle lipid synthesis protects against fat-induced insulin resistance. We hypothesized that rates o...

Autophagy, a lysosomal catabolic pathway for long-lived proteins and damaged organelles, is crucial for cell homeostasis, and survival under stressful conditions. During starvation, autophagy is induced in numerous organisms ranging from yeast to mammals, and promotes survival by supplying nutrients and energy. In the early neonatal period, when transplacental nutrients supply is interrupted, s...

this study was carried out on 10 crossbred male sheep aged 1-1.5 year. an innervated crosskopf abomasal fundic pouch was made in each animal and effect o f starvation an d feeding on abomasal volume and composition were assesed . the results indicated that during starvation, volume of secretion , total acidity and k concentration decreased to a low level, while ph and na concentration reached h...

A conjugated poly(fluorene-thiophene) donor and a tethered phenanthro[9,10-d]imidazole acceptor (PFT-PI) was used as the active layer in flexible nonvolatile resistor memory devices with low threshold voltages (±2 V), low switching powers (∼100 μW cm(-2)), large ON/OFF memory windows (10(4)), good retention (>10(4) s) and excellent endurance against electric and mechanical stimulus.

OBJECTIVES The aim of this study was to investigate the effects of 8-week endurance and resistance exercise training on release of brain natriuretic peptide. MATERIALS AND METHODS Study population was categorized into 4 groups: Group-1 (n = 6) consisted of sedentary individuals who volunteered to complete 8-weeks of endurance exercise; Group-2 (n=6) consisted of sedentary individuals who volu...

Pyruvate dehydrogenase kinase (PDK) catalyzes phosphorylation and inactivation of the pyruvate dehydrogenase complex (PDC). Two isoforms of this mitochondrial kinase (PDK2 and PDK4) are induced in a tissue-specific manner in response to starvation and diabetes. Inactivation of PDC by increased PDK activity promotes gluconeogenesis by conserving three-carbon substrates. This helps maintain gluco...
