vacuolar h+-translocation pyrophosphatase (v-ppase) and na+/h+ antiporter (v-na+/h+) are important transporters in plant cells and have essential roles against abiotic stresses. in this study, the effects of salt stress were surveyed on the transcription of v-ppase pump and na+/h+ antiporter genes at early times of nacl treatment in roots of halophytic grass leptochloa fusca through the real ti...

background: hormones can play a significant role in the pathogenesis of multiple sclerosis (ms). the aim of this study was to compare levels of ghrelin, leptin, and testosterone hormones of ms patients with healthy subjects, and assess the relationship between levels of peptide hormone and sex hormones in ms patients. methods: 35 ms patients with definite relapsing remitting multiple sclerosis ...

background : leptin and its receptors have been found in the human gastric mucosa.  its secretion by gastric mucosa has generated interest in its probable role in the gastrointestinal tract and pathophysiology of diseases.   objective: to determine any possible correlation between serum leptin level and pathological findings in patients with duodenal ulcer (du).   methods: in a cross-sectional ...

introduction: studies have shown the regulatory role of leptin in bone formation, its expression in adipose tissue as well as increased levels in circulation following the adminstration of inflammatory stimuli such as lipopolysaccharides (lps). however, there is little data evaluating the role of leptin in inflammatory periapical lesions. the aim of this study was to evaluate the presence and c...

Previously, 40% food restriction of male Siberian hamsters over 21 days in short-day (SD) photoperiod induced characteristic changes in expression of hypothalamic arcuate nucleus energy balance genes; mRNAs for neuropeptide Y, agouti-related peptide, and leptin receptor were upregulated, and those of proopiomelanocortin and cocaine- and amphetamine-regulated transcript were depressed. The prese...

Background and Objectives: Calorie restriction (CR) is one of the proven methods of extending lifespan and slowing aging. Leptin is a nutritionally regulated adipokine that has been proposed as a possible key signal in the adaptive responses relevant to CR. Under CR, plasma leptin levels decrease, thus it was hypothesized that leptin administration may counteract CR-induced weight loss. Therefo...

results there was a significant increase (p < 0.05) in leptin levels on day 14 (12.75 + 5.8 ng/ml) and day 21 (12.91 + 3.2 ng/ml) for age group 18-30 years compared to day 14 (11.60 + 3.2 ng/ml) and day 21 (11.60 + 3.2 ng/ml) for age group 31-40 years. leptin was positively correlated with fsh on day 14, with lh on day 7 and day 21; likewise, with progesterone on day 21 and day 28 and with estr...

Craniopharyngioma (CP) is a benign tumor with high rate of obesity and frequent recurrence. Moreover, the role leptin/leptin receptors axis in prognosis CP still unknown. Plasma leptin concentration mRNA expression were assessed patients CP. association between axis, weight-related outcomes, progression-free survival (PFS) explored patients. Leptin overexpressed tissue compared to normal brain ...
