Afferent-inherent regulation of myosin heavy chain isoforms in rat muscle spindles.

Whether afferents exert their morphogenetic influence on spindles through release of trophic factors at intrafusal fiber junctions or via participation in proprioceptive pathways which modulate the motor activity to muscles was investigated by…

Expression of alpha-cardiac myosin heavy chain in normal and denervated rat muscle spindles.

Whether any fibers in rat hindlimb muscles express alpha-cardiac myosin heavy chain (MHC) is uncertain. Expression of alpha-cardiac MHC mRNA and the polypeptide for which it codes were examined in control and denervated rat muscle spindles using in…

Onset of exercise shifts operating point of arterial baroreflex to higher pressures.

This study was designed to test the hypothesis that the increase in sympathetic nerve activity (SNA) and mean arterial pressure (MAP) at the onset of exercise is dependent on a rapid upward shift of the operating point of the arterial baroreflex. To…

Gender difference in cardiopulmonary reflex inhibition of sympathetic nerve activity.

We tested the hypothesis that reflex responses to mechanical [increase in left atrial pressure (LAP) 0-25 mmHg] and chemical stimulation [left atrial injection of phenylbiguanide (PBG), 0.5-10 mg/kg] of cardiopulmonary receptors are greater in female…

Characterization of vascular endothelial growth factor (VEGF) in the uterine cervix over pregnancy: effects of denervation and implications for cervical ripening.

Bilateral neurectomy of the pelvic nerve (BLPN) that carries uterine cervix-related sensory nerves induces dystocia, and administration of its vasoactive neuropeptides induces changes in the cervical microvasculature, resembling those that occur in…

Transient Expression Of A Slow-tonic Mhc Isoform By Extrafusal Fibers In The Developing Rat

ALD 19, a monoclonal antibody that recognizes the slow-tonic myosin heavy chain (MHC) isoform, has been used extensively as a marker for nuclear bag intrafusal fibers of muscle spindles in developing and adult rats. Extrafusal fibers of adult rat…

Differential-effects Of Neonatal Denervation On Intrafusal Muscle-fibers In The Rat

The response of developing muscle spindles to denervation was studied by sectioning the nerve to the medial gastrocnemius muscle of rats at birth. The denervated spindles were examined daily throughout the first postnatal week for changes in…
