PENEFSKY Z, ELWOOD J
Comp Biochem Physiol A Physiol
. 1996 Jun;
114(2):175-87.
PMID: 8925433
Mechanical responses were compared between controls, developing Sprague-Dawley rat papillary muscle and age-matched weanlings fed with Torula yeast, a food source deficient in chromium. At 8 weeks postnatal, deficient rats...

Comp Biochem Physiol Physiol
. 1994 Sep;
109(1):1-22.
PMID: 8076447
The contraction-relaxation cycle of the heart represents the combined action of a variety of different components of the myocytes. For many years an 'index' of contractility has been sought as...

PENEFSKY Z, Diamond E
Comp Biochem Physiol Comp Physiol
. 1992 Dec;
103(4):747-55.
PMID: 1361898
1. A comparison was made of the mechanical performance of heart muscle from mouse, an atricial mammal, with corticosterone as glucocorticoid and spiny mouse (Acomys cahirinus), a precocial mammal, with...

PENEFSKY Z, McCann F
J Dev Physiol
. 1989 Jul;
12(1):27-33.
PMID: 2614038
Action potentials recorded from perinatal rat ventricles exhibited a plateau (phase 2), followed by a rapid repolarization characteristics of all mammalian ventricular cells. Within the second postnatal week, a number...

Katz S, PENEFSKY Z, McGinnis M
J Mol Cell Cardiol
. 1988 Apr;
20(4):323-8.
PMID: 3172245
Glucocorticoid hormones alter functional cardiac responses in the rat heart. In the neonatal rat heart, glucocorticoid treatment on post-natal day 2 alters heart function for up to 3 weeks post-injection,...

PENEFSKY Z
Comp Biochem Physiol C Comp Pharmacol Toxicol
. 1988 Jan;
90(1):133-44.
PMID: 2904853
1. The negative force-frequency response of normal rat heart was accentuated when the animals were adrenalectomized. Treatment of adrenalectomized animals with dexamethasone restored the normal force-frequency response. 2. Total adrenalectomy...

PENEFSKY Z, Wolfe J, Greengard O, Bernstein J
J Dev Physiol
. 1986 Oct;
8(5):333-45.
PMID: 3794225
Age-dependent changes in the mechanical responses of developing Fisher rat heart during the first three postnatal weeks were studied in relation to the hypothesis that the abnormality observed in the...

PENEFSKY Z, BUCKLEY N, Robinson T, Sorensen A
Comp Biochem Physiol A Comp Physiol
. 1985 Jan;
80(3):399-409.
PMID: 2858319
Mechanical responses of myocardium from 16 piglets were studied from 18 hr to 12 days after birth. Tension, time and velocity parameters of contraction and relaxation were determined for every...

PENEFSKY Z, Scott W
Comp Biochem Physiol A Comp Physiol
. 1982 Jan;
72(3):559-69.
PMID: 6126299
1. Mechanical responses of young and old rat myocardium to increasing rates of stimulation were compared. As the animals aged, we found a significant enhancement of the negative force-frequency response...
