Evaluation of skeletal muscle regeneration in experimental model after malnutrition

Braz. j. biol; 77 (1), 2017
Abstract The aim of this study was to analyze muscle regeneration after cryoinjury in the tibialis anterior muscle of young rats that were malnourished and then recovered. Forty Wistar rats were divided into a nourished group that received a normal protein diet (14% casein) for 90 days and a malnourished...

Jumping in aquatic environment after sciatic nerve compression: nociceptive evaluation and morphological characteristics of the soleus muscle of Wistar rats

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT Objective To evaluate the effect of jumping in aquatic environment on nociception and in the soleus muscle of trained and not trained Wistar rats, in the treatment of compressive neuropathy of the sciatic nerve. Methods Twenty-five Wistar rats were distributed into five groups: Control, Lesi...

Electrical stimulation attenuates morphological alterations and prevents atrophy of the denervated cranial tibial muscle

Einstein (Säo Paulo); 15 (1), 2017
ABSTRACT Objective To investigate if electrical stimulation through Russian current is able to maintain morphology of the cranial tibial muscle of experimentally denervated rats. Methods Thirty-six Wistar rats were divided into four groups: the Initial Control Group, Final Control Group, Experimental...

90-kDa N-domain angiotensin I-converting enzyme (ACE): possible marker for hypertension in a renal transplant model

J. bras. nefrol; 39 (1), 2017
Abstract Introduction: Hypertension is nearly universal in kidney transplant and several factors are associated with post transplant hypertension, including immunosuppressive medications and genetic predisposition. Objective: The aims were to evaluate the effects of spontaneously hypertensive rats (SHR...

Comparative analysis of two different models of swimming applied to pregnant rats born small for pregnant age

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT The aim of this study was to compare two models of swimming applied to pregnant rats born small for pregnancy age (SPA). Diabetes was chemically induced in adult female rats to develop an inadequate intrauterine environment, leading to birth of a SPA offspring. In adulthood, the female SPA rats ...

Grape juice increases the BDNF levels but not alter the S100B levels in hippocampus and frontal cortex from male Wistar Rats

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Several studies have shown that a high consumption of vegetables and fruits is consistently associated with a low risk of oxidative stress-induced diseases, which includes some degenerative diseases such as amyotrophic lateral sclerosis, Alzheimer and Parkinson. Therefore, the objective of this ...

Autophagy protects against neural cell death induced by piperidine alkaloids present in Prosopis juliflora (Mesquite)

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Prosopis juliflora is a shrub that has been used to feed animals and humans. However, a synergistic action of piperidine alkaloids has been suggested to be responsible for neurotoxic damage observed in animals. We investigated the involvement of programmed cell death (PCD) and autophagy on the m...

Effect of Bauhinia holophylla treatment in Streptozotocin-induced diabetic rats

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Bauhinia holophylla, commonly known as "cow's hoof", is widely used in Brazilian folk medicine for the diabetes treatment. Therefore, the aim of this study was at evaluating the aqueous extract effect of Bauhinia holophylla leaves treatment on the streptozotocin-induced diabetic rats. Diabetes w...

Tryptophan overloading activates brain regions involved with cognition, mood and anxiety

An. acad. bras. ciênc; 89 (1), 2017
ABSTRACT Tryptophan is the only precursor of serotonin and mediates serotonergic activity in the brain. Previous studies have shown that the administration of tryptophan or tryptophan depletion significantly alters cognition, mood and anxiety. Nevertheless, the neurobiological alterations that follow the...
