INTRODUCTION AND METHODS. Serotonin N-acetyltransferase (NAT) is a rate-limiting enzyme in melatonin biosynthesis. Its activity (which parallels melatonin levels) follows a diurnal rhythm with high values at night and low values during day-hours of any light-dark illumination cycle (1). In retinas NAT is expressed by photoreceptors (2). Exposure of animals to light at night suppresses the noctu...

Phytoremediation is an efficient approach that uses plants to remediate the polluted environments.The aim of this research was to evaluate phytoremediation ability of Artemisia aucheriin the contaminated soil to Cadmium, Lead, Zinc and Nickel. A greenhouse experiment was performed to investigate the effect of Municipal Solid Waste Compost (MSWC) on phytoremediation efficiency of A....

People who supplement their diets with extra zinc usually have potentially harmful changes in lipoprotein metabolism. Because zinc can interfere with copper metabolism and copper deficiency has produced similar changes in lipid metabolism in animals and people, the hypothesis that lipid alterations from high zinc intakes are accompanied by changes in copper metabolism was tested. Progenies of s...

In 14 patients undergoing open-heart operations the haemodynamic effects of diazepam 0.4 mgkg(-1) followed by ketamine 2 mg kg(-1) were studied. In eight patients undergoing coronary bypass surgery, the mean arterial pressure decreased significantly after diazepam from 90.3 +/-7.4 (SEM) to 78.0 +/-5.0 mm Hg (P less than 0.05). However, no changes occurred in six patients undergoing valve replac...

Abstract Fly ash represents a promising alternative source of rare earth elements (REE). However, information on REE containing mineral phases and their association with other fly components, vital for recovery from ash, is currently lacking. Herein, the mass fraction, distribution, crystallography solid-state chemistry REE, U Th in Nigerian simulated samples were characterised using range labo...

The hormonal responses to anaesthesia and cardiac surgery were studied in 20 patients. Ten patients were anaesthetized with fentanyl 60 microgram kg-1 and nitrous oxide in oxygen and 10 with etomidate 0.3 mgkg-1 and nitrous oxide in oxygen plus halothane. There were no significant changes in cortisol, growth hormone or insulin concentrations in response to surgery in either group, although cort...
