Background: An important factor in the prevention of industrial accidents is the ability of employees to maintain awareness of the work situation, understand the information it holds, and predict how situations will develop. In the present study, we examined the role of fatalistic beliefs and safety climate in predicting occupational situation awareness (SA) among workers.   Mate...

where [E]/[E], is fractional enzyme activity, and t is reaction time. The constants C and k were determined graphically (Defares & Sneddon, 1960). The results of the effect of diethyl pyrocarbonate on DEAE-cellulose column-chromatography fractions obtained from two samples of normal gastric mucosa and three samples of stomach adenocarcinoma are presented in summary form in Table I. It will be s...

A physical deduction of the FN = kh 3/2 relation (where FN is normal force, k penetration resistance and h penetration depth) for conical/pyramidal indentation loading curves has been achieved on the basis of elementary mathematics. The indentation process couples the productions of volume and pressure to the displaced material that often partly plasticizes due to such pressure. As the pressure...

We have studied the mechanical properties of encapsulated Saccharomyces cerevisiae yeast cells by performing AFM force measurements. Single living cells have been coated through the alternate deposition of oppositely charged polyelectrolyte layers and mechanically trapped into a porous membrane. Coated and uncoated cells in presence/absence of bud scars, i.e. scars resulting from previous buddi...

Background: Tumor necrosis factor-alpha (TNF-α) is a proinflammatory cytokine that plays an immunomodulatory role in a variety of systemic and dermatologic disease. Its blockade can be achieved by using specific inhibitors like etanercept. At present, etanercept is approved for rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, juvenile idiopathic arthritis and psoriasis treatme...

Am J Physiol Endocrinol Metab 281: E676–E682, 2001.—Muscle wasting affects large numbers of people, but few therapeutic approaches exist to treat and/or reverse this condition. The b2-adrenoceptor agonist clenbuterol produces a ...

BACKGROUND Tumor necrosis factor-alpha (TNF-a) is a proinflammatory cytokine that plays an immunomodulatory role in a variety of systemic and dermatologic diseases. Currently, three anti-TNF-a drugs are available in North America- infliximab (approved in the U.S. for the treatment of rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, ulcerative colitis, and psoriatic arthritis), eta...

nervous system. He has been a beleagured champion in maintaining the inadequacy of explaining the action potential in purely physical terms, and pointing out shortcomings of the chemical transmitter theory. His work has stimulated much research and probably will continue to do so. For example, although few readily accept a direct involvement of ACh in the propagation of the action potential, no...
