How other members of the top management team see the nurse executive.

This study compared how top-level organizational groups within Veterans Affairs Medical Center (VAMC) top management teams perceived nurse executives' participation in strategic decision making. Nurse executives' perceptions of their own involvement in strategic decision making generally agreed with the views of both chiefs of staff and directors. However, the associate director's perceptions of the nurse executive's involvement often differed significantly with those of the nurse.

Decision-making activity and influence of nurse executives in top management teams.

This study assesses the impact on decision-making when introducing the nurse executive into the top management team (TMT) in Veterans Affairs Medical Centers. Results indicate that nurse executives formally elevated to the TMT were no more likely to perceive greater involvement in decision-making than non-TMT nurse executives or nurses informally appointed to the TMT. However, nurse executives in all categories perceived themselves as more involved in strategic decisions than other TMT members.

Complementation of the Saccharomyces cerevisiae plasma membrane H+-ATPase by a plant H+-ATPase generates a highly abundant fusicoccin binding site.

Accumulating evidence suggests that the H+-ATPase of the plant plasma membrane is activated by a direct, reversible interaction with 14-3-3 proteins involving the displacement of the C-terminal autoinhibitory domain of the enzyme. The fungal phytotoxin fusicoccin (FC) appears to stabilize this H+-ATPase.14-3-3 complex, thus leading to a persistent activation of the H+-ATPase in vivo.

Five new 14-3-3 isoforms from Nicotiana tabacum L.: implications for the phylogeny of plant 14-3-3 proteins.

About thirty years after the initial identification of 14-3-3 proteins in mammalian brain, they are now thought to be ubiquitous among eukaryotes. We identified five cDNAs encoding 14-3-3 proteins of Nicotiana tabacum L. using a polymerase chain reaction (PCR)-based screening strategy.

Impaired microvascular vasoconstrictive responses to vasopressin in septic rats.

Objective: To evaluate mechanisms of vasodilation in sepsis by comparing responses of resistance arterioles to vasopressin in rat cremaster muscle of septic and control rats.

Design: Prospective, experimental study.

Setting: Experimental animal laboratory.

Nitric oxide synthase inhibition reverses arteriolar hyporesponsiveness to endothelin-1 in septic rats.

Persistent vasodilation refractory to vasopressor agents is the hemodynamic abnormality characteristic of septic shock. Induction of nitric oxide synthase (NOS) by sepsis-induced cytokines has been hypothesized to play a pathogenetic role in this refractory vasodilation. To evaluate the mechanism of vasodilation in sepsis, we used in vivo videomicroscopy to measure responses of resistance arterioles (15-20 microm) to topical suffusion of the potent vasoconstrictor, endothelin-1 (ET-1), in rat cremaster muscle.

Cardiac endothelin release and infarct size, myocardial blood flow, and ventricular function in canine infarction and reperfusion.

Background: The potent vasoconstrictor endothelin-1 (ET) may play an important pathophysiologic role in acute myocardial infarction, but its precise effects are incompletely understood. The purpose of this study was to evaluate the interrelationships between cardiac ET-1 release and infarct size, myocardial blood flow, and ventricular function.

Methods: Fifteen closed chest dogs underwent 3 hours of coronary artery occlusion followed by 3 hours of reperfusion.

Workers' perceptions of discrepancies between chronological age and personal age: you're only as old as you feel.

A large manufacturing organization was surveyed to determine whether workers perceive discrepancies between their chronological ages and the ages they "feel" themselves to be. A substantial proportion (61.5%) of the sample did report such discrepancies.

Aphasia: providing better nursing care.

The ability to communicate affects the total person and penetrates nearly every aspects of living. To best assist those persons experiencing language loss, the nurse needs to gain basic knowledge about the types of aphasia and about techniques to guide these persons in regaining communication skills that promote self-care. For the aphasic, relearning each small step in communication is a triumph.

Lymphocyte transformation, rosette formation and behaviour of immunoglobulins in sarcoidosis.

1. Patients with sarcoidosis indicated significant decrease of the mean value of lymphocyte transformation (LT) in all stages and all periods of sarcoidosis. In chronic sarcoidosis the mean value of LT was significantly lower (27.
