31P NMR spectroscopy, chemical analysis, and free Mg2+ of rabbit bladder and uterine smooth muscle.

• Martin J. Kushmerick, P F Dillon, R. A. Meyer, T. R. Brown, J M Krisanda, H. Lee Sweeney
• The Journal of biological chemistry
• 1986

31P NMR spectra of isolated rabbit bladder and uterus were obtained under steady-state arterial perfusion in vitro at rest and while stimulated. The spectra contained seven major peaks:… (More)

ATP utilization (delta approximately P) during an isometric contraction has been studied in terms of both measurements of oxygen consumption and lactate production as well as of the tissue nucleotide… (More)

Dependence of force, velocity, and O2 consumption on [Ca2+]o in porcine carotid artery.

• J M Krisanda, R. J. Paul
• The American journal of physiology
• 1988

The relationship between extracellular calcium concentration ([Ca2+]o), isometric force (Fo), unloaded shortening velocity (Vus), and the rate of ATP utilization (JATP) were studied in vascular… (More)

Tight binding of arterial myosin to skeletal F-actin.

• J M Krisanda, R. A. Murphy
• The Journal of biological chemistry
• 1980

A study of the K+-activated myosin ATPase activity, which was measured at high ionic strength in the absence of divalent cations, permitted estimates of the actin-myosin interaction under conditions… (More)

High affinity of various smooth muscle myosins for skeletal F-actin demonstrated by enzyme kinetics and electron microscopy.

• J M Krisanda, Steve Breese, R. A. Murphy
• Biochimica et biophysica acta
• 1982

Myosins isolated from mixed rabbit skeletal muscle and several smooth muscles differ with respect to the rate of ATP hydrolysis and the degree of inhibition of the potassium-activated ATPase activity… (More)

Phosphagen and metabolite content during contraction in porcine carotid artery.

• J M Krisanda, R. J. Paul
• The American journal of physiology
• 1983

Previous studies (Paul, R. J. Chemical energetics of vascular smooth muscle. In: Handbook of Physiology: The Cardiovascular System. Bethesda, MD: Am. Physiol. Soc., 1980, p. 201-235) have shown that… (More)

Energetics of isometric contraction in porcine carotid artery.

• J M Krisanda, R. J. Paul
• The American journal of physiology
• 1984

The rate of ATP utilization ( JATP ) and unloaded shortening velocity ( Vus ) of porcine carotid artery were studied during tension development and maintenance to assess the importance of mechanisms… (More)

The effects of calcium on smooth muscle mechanics and energetics.

• R. J. Paul, Joseph Strauss, J M Krisanda
• Progress in clinical and biological research
• 1987

In smooth muscle isometric force, shortening velocity, the ATP utilization under isometric conditions, and tension cost are all functions of calcium. This suggests that both cross bridge number and… (More)

Effect of decreased pH on force and phosphocreatine in mammalian skeletal muscle.
