traffic accident has increased in the last decade. one of the most important outcomes of accident is spinal cord injury (sci). so, cell therapy is obtained a greater attention in most fields of medicine because of its potential for incurable diseases through replacing of dead cells. the current study aims to describe the important of locomotor functional and structural connection of the spinal ...

Inhibition of ammonia excretion (J(amm)) is a common response to Cu exposure in freshwater (FW) and seawater (SW) organisms. To determine the mechanism of this response, a euryhaline species of guppy (Poecilia vivipara) was exposed to 20 μg Cu/l in FW (0 ppt) and SW (25 ppt) for 96 h. In both salinities, Cu transiently inhibited ammonia excretion (J(amm)) followed by a full recovery by the end ...

Treatment with the atypical antipsychotic drug olanzapine is frequently associated with development of obesity and insulin resistance. Treatment-induced weight gain has been suggested to be the main contributing factor of diminished insulin sensitivity. This study evaluated the effects of short-term treatment with olanzapine on 12h plasma prolactin and cortisol concentrations in healthy men. Th...

Dehydroepiandrosterone (DHEA) is important for human health, especially for women. All estrogens and practically half of androgens are synthesized from DHEA in peripheral tissues. However, the mechanism and exact target tissues of DHEA biotransformation in the female are not fully clear. The present study showed that maximal content of androstenedione (AD) and testosterone (T) were observed at ...

Ionic status during early development was investigated in the purple sea urchin. Whole body cation concentrations (Ca(2+), Na(+), K(+), Mg(2+)), unidirectional Ca(2+) uptake rates measured with (45)Ca(2+), Ca(2+)-ATPase activity, and growth were examined at 12h intervals over the first 96h of development. Whole body Ca(2+) concentration was low initially but increased steadily by >15-fold throu...

PURPOSE Data are accumulating to support the involvement of inflammatory mechanisms in the pathogenesis and course of epilepsy. METHODS The aim of this study was to examine seizure-induced changes in plasma concentrations of interleukin-6 (IL-6), interleukin-1 receptor antagonist (IL-1Ra), and interleukin-1 beta (IL-1β) in 23 patients with epilepsy undergoing a video-electroencephalography (E...

BACKGROUND/AIMS Kidney abnormalities are one of the main chronic complications of sickle cell disease (SCD). The aim of this study is to investigate the occurrence of renal tubular abnormalities among patients with SCD. METHODS This is a prospective study with 26 SCD adult patients in Brazil. Urinary acidification and concentration tests were performed using calcium chloride (CaCl2), after a ...

UNLABELLED Angiotensin II has articularly shown to play a key role in the regulation of inflammatory processes in hypertension. AIM The present study aims to correlate the angiotensin II-induced hypertension 4th systemic inflammation. MATERIAL AND METHODS We conducted an experimental study on Wistar male rats who received Ang II via subcutaneous miniosmotic pumps for 2 weeks. Rats were expo...

Based on the cooperative virulence index (c.f.) and LC(50) of fipronil, the interaction effect between short-term heat pretreatment and fipronil on 2(nd) instar larvae of diamondback moth (DBM), Plutella xylostella (Linnaeus), was assessed. The results suggested that pretreatment of the tested insects at 30 °C for 2, 4 and 8h could somewhat decrease the toxicity of fipronil at all set concentra...

Tetrodotoxin (TTX) was intramuscularly administered to non-toxic cultured specimens of the pufferfish Takifugu rubripes to investigate TTX transfer/accumulation profiles in the pufferfish body. In two groups of test fish administered either 50MU/individual of TTX standard (purified TTX; PTTX) or crude extract of toxic pufferfish ovary (crude TTX; CTTX), TTX rapidly transferred from the muscle v...
