A high-carbohydrate diet induces greater inflammation than a high-fat diet in mouse skeletal muscle

Braz. j. med. biol. res; 53 (3), 2020
We previously reported that both the high-carbohydrate diet (HCD) and high-fat diet (HFD) given for two months promote lipid deposition and inflammation in the liver and brain of mice. The results obtained indicate a tissue-specific response to both diets. Herein, we compared the effects of HCD and HFD o...

Morphometric and molecular muscle remodeling after passive stretching in elderly female rats

Clinics; 75 (), 2020
OBJECTIVES: To determine the effects of three sessions of a passive stretching exercise protocol on the muscles of elderly female rats. METHODS: The effects of the stretching exercises on the soleus muscle were analyzed using immunohistochemistry [tissue inhibitors of matrix metalloproteinases (TIMP), t...

Mechanical evaluation of tibial fixation of the hamstring tendon in anterior cruciate ligament double-bundle reconstruction with and without interference screws

Clinics; 75 (), 2020
OBJECTIVE: The objective of this study was to compare two postero-lateral bundle (PLB) tibial fixation techniques for the reconstruction of the anterior cruciate ligament with double bundle: a technique without the use of an interference screw, preserving the native tibial insertion of the tendons of the...

The effects of stretching on muscle morphometry of ovariectomized rats

Abstract Introduction: Ageing is responsible for structural alterations, declining of all physiological variables, including range of motion and skeletal muscle function, known as sarcopenia. Objective: The aim of the study was to evaluate the effects of stretching on muscle morphometry in ovariectomiz...

Stem cells in end-to-side neurorrhaphy. Experimental study in rats

Acta cir. bras; 35 (12), 2020
Abstract Purpose: To evaluate the influence of mesenchymal stem cells from adipose tissue in the end-to-side neurorrhaphy, focusing in the nerve regeneration and the muscle reinnervation in acute trauma. Methods: 140 animals were randomly divided in seven groups: control, denervated, end-to-side neuror...

Quercetin modulates age-induced changes in the transcript levels of some apoptosis related genes in the skeletal muscles of male rats

Adverse changes occur gradually in the skeletal muscles with age via continuous exposure to oxidative stress. Quercetin, a member of the flavonoids family, possesses anti-oxidative and radical-scavenging activities. Therefore, this study investigated the role of quercetin to modulate age-induced changes ...

Shark liver oil consumption decreases contractility in EDL muscle of trained rats

Abstract Introduction: Professional and recreational athletes make daily use of nutritional supplements to improve physical performance. Polyunsaturated fatty acids (PUFAs) have been used in this sense. N-3 PUFA, particularly eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids are involved in importa...

Creatine supplementation plus neuromuscular electrical stimulation improves lower-limb muscle strength and quality of life in hemodialysis men

Prevalence of the palmaris longus and its impact on grip strength in elite gymnasts and non-athletes

Int. j. morphol; 37 (4), 2019
In elite athletes, the palmaris longus (PL) presence has a potential contribution to hand strength, smaller reaction time, better shooting speed and power. The aim of this study was to investigate the prevalence of PL in elite competitive artistic gymnasts and its impact on grip strength compared to a co...
