The influence of renal nerves on the effects of concurrent NO synthase inhibition (10 mg kg(-1) b.w. i.v. L-NAME) and ET(A)/ET(B) receptor inhibition (10 mg kg(-1) b.w. i.v. bosentan) on renal excretory function and blood pressure in conscious spontaneously hypertensive rats (SHR) was investigated. L-NAME increased blood pressure, urine flow rate, fractional excretion of sodium, chloride and ph...

The development and life stages of Meloidogyne cruciani on tomato was studied at 28 C. Roots of 2-wk-old 'Rutgers' tomato seedlings were exposed to inoculum for 24 h, rinsed, and the seedlings repotted. No major changes in juvenile development were observed prior to 8 days after inoculation. At 11 days the second-stage juvenile had enlarged considerably. The genital primordium had not yet asume...

Schistosomiasis has been a public health burden in a number of countries across the globe for centuries and probably beyond. The World Health Organization and partners are currently preparing to move towards elimination of this disease. However, given the historical challenges and barriers to ridding areas of this water-borne parasite infection, we question whether the current targets for elimi...

Three-dimensional phase-field simulations are employed to investigate rod-type eutectic growth morphologies in confined geometry. Distinct steady-state solutions are found to depend on this confinement effect with the rod array basis vectors and their included angle (α) changing to accommodate the geometrical constraint. Specific morphologies are observed, including rods of circular cross secti...

Item test analysis is an aid to identify items that need to be eliminated from an assessment. An automatic elimination procedure based on item statistics, therefore, could help to increase the quality of a test in an objective manner. This was investigated by studying the effect of a standardized elimination procedure on the test results of a second-year course over a period of 6 successive yea...

In Latin American and Caribbean (LAC) countries, the number of cases of dog-mediated human rabies is at its lowest since the onset of the Regional Program for Rabies Elimination in 1983, a commitment from LAC countries to eliminate dog-mediated rabies coordinated by the Pan American Health Organization. Despite minor setbacks, the decline in the number of human cases has been constant since 198...
