Stretch Injuries of Skeletal Muscles: Experimental Study in Rats' Soleus Muscle
(Soc Chilena Anatomia, 2009-12-01)
The study aimed to verify the physiological injury behavior by stretching the soleus muscle of rats, using a noninvasive experimental model. Twenty-four rats were used and divided into three groups of eight animals: control ...
Rho-kinase activity is upregulated in the skeletal muscle of aged exercised rats
(2019-12-01)
There is a gap in the knowledge regarding the regulation of glucose uptake in skeletal muscle during the development of insulin resistance in the elderly. Rho-Kinase (Rock) signaling has been demonstrated as a crucial ...
Histoenzymological and ultrastructural changes in lateral muscle fibers of Oreochromis niloticus (Teleostei: Cichlidae) after local injection of veratrine
(2001-12-01)
The effects of veratrine have been investigated in mammalian, amphibian, and crustacean muscle, but not in fish. In this work, the action of veratrine was studied in the lateral muscle of the freshwater teleost Oreochromis ...
Myostatin and follistatin expression in skeletal muscles of rats with chronic heart failure
(Wiley-Blackwell Publishing, Inc, 2010-02-01)
P>Skeletal muscle abnormalities can contribute to decreased exercise capacity in heart failure. Although muscle atrophy is a common alteration in heart failure, the mechanisms responsible for muscle mass reduction are not ...
Morphology and skeletal muscle growth in pirarucu Arapaima gigas Cuvier, 1817 (Teleostei, Arapaimidae)Morfologia e crescimento do músculo estriado esquelético no pirarucu Arapaima gigas Cuvier, 1817 (Teleostei, Arapaimidae)
(2008-01-01)
The aim of this work was to evaluate the morphological and growth characteristics of skeletal muscle tissue in pirarucu (Arapaima gigas) using alevins (50 days old) and juveniles (1 year old). Muscle samples were collected ...
Mouse extensor digitorum longus and soleus show distinctive ultrastructural changes induced by veratrine
(2002-07-01)
We investigated whether veratrine (5 μl, 10 ng/kg) injected into the mouse extensor digitorum longus (EDL) (fast-twitch) and soleus (SOL) (slow-twitch) muscles provokes distinctive ultrastructural disturbances 15, 30 and ...
Morphological aspects of neuromuscular junctions and gene expression of nicotinic acetylcholine receptors (nAChRs) in skeletal muscle of rats with heart failure
(Springer, 2011-12-01)
HF is syndrome initiated by a reduction in cardiac function and it is characterized by the activation of compensatory mechanisms. Muscular fatigue and dyspnoea are the more common symptoms in HF; these may be due in part ...
High-intensity exercise training induces mitonuclear imbalance and activates the mitochondrial unfolded protein response in the skeletal muscle of aged mice
(Springer, 2020-07-31)
The impairment of mitochondrial metabolism is a hallmark of aging. Mitonuclear imbalance and the mitochondrial unfolded protein response (UPRmt) are two conserved mitochondrial mechanisms that play critical roles in ensuring ...
