The purpose of this investigation was to determine whether there is a link between sarcoplasmic reticulum (SR) glycogen status and SR Ca2+ handling. In this investigation, skeletal muscle SR was purified from female Sprague-Dawley rats (200-250 g). Glycogen was extracted from the SR purified from one hindlimb, whereas the SR purified from the contralateral limb served as control. Before removal...

HMG-CoA reductase inhibitors have been associated with skeletal muscle myopathy, ranging from asymptomatic elevations of serum creatine kinase (CK) activity to rhabdomyolysis. In this study, we assessed the effects of addition of different concentrations of simvastatin and pravastatin on growth and differentiation of cultured primary rat skeletal muscle cells. Protein concentrations, CK activit...

Results from different experimental systems demonstrate that increased oxidative damage plays a role in normal aging and age-associated pathology. In the current study, long-term cultures of hippocampal neurons were examined as a model system. It was established that neuronal survival in long-term culture decreases according to the Gompertz law and that neuronal "aging in the dish" is associate...

Strigolactone (SL), auxin, and cytokinin (CK) are hormones that interact to regulate shoot branching. For example, several ramosus (rms) branching mutants in pea (Pisum sativum) have SL defects, perturbed xylem CK levels, and diminished responses to auxin in shoot decapitation assays. In contrast with the last of these characteristics, we discovered that buds on isolated nodes (explants) of rms...

Towards the improvement of plant productivity in saline–alkali soils, application arbuscular mycorrhizal fungi (AMF) is an intensive topic research. For this study, three inoculation treatments, namely, autoclaved AMF inocula (CK), Funneliformis mosseae (FM), and Corymbiglomus tortuosum (CT), four NaCl levels, 0, 50, 100, 150 mM were established to investigate growth physiological responses Gle...

To investigate the effects of different aging times, three An–tea samples were selected for comparison with a non-aged sample as control (CK, one-year-old) and labeled high-aged (HAS, 12 years old), medium-aged (MAS, 7 low-aged (LAS, 2 old). Changes in volatile components investigated using headspace–solid-phase microextraction (HS-SPME) combined gas chromatography–mass spectrometry (GC-MS). Th...
