in order to study the effects of on-farm seed priming and sowing date on germination percentage, germination speed, and some growth indices of three soybean cultivars, a field experiment was carried out in three replications using a split plot factorial in a randomized complete block design. main plots were representative of two sowing date (5th and 21th of may), while subplots included combina...

The aim of this study is to prepare biogenic sulphides by using bacteria for the removal of zinc cations from their solutions. The production was realized in a bioreactor under anaerobic conditions at 30 °C. Sorbents were prepared by sulphate-reducing bacteria in different nutrient medium modifications, under two modes of bacteria cultivation. Created precipitates of iron sulphides were removed...

A 17-year-old girl with haemolytic anaemia, parenchymal livel disease and gallbladder calculi, is reported. Kayser-Fleischer rings, transaminasaemia, deficiency of ceruloplasmin, increased cupriuria, and nodular cirrhosis of the liver, confirmed the diagnosis of Wilson's disease. Penicillamine therapy had to be interrupted a short time after it was started, because of penicillamine-induces acut...

Anchovy oil is a very suitable supplementary ingredient for fish feeds due to the essential fatty acid composition. The acute toxicity of zinc and copper ions for rainbow trout (Oncorhynchus mykiss Walbaum 1792) were evaluated by static bioassays. The average weight and lenght of fish used in the zinc experiments were 3,02 ±0.21 g and 6.52 ±0.12 cm, respectively, while the tests with copper ion...

BACKGROUND There is a clinical need for new therapeutic products against Herpes simplex virus (HSV). The pomegranate, fruit of the tree Punica granatum L, has since ancient times been linked to activity against infection. This work probed the activity of pomegranate rind extract (PRE) and co-administered zinc (II) ions. MATERIALS AND METHODS PRE was used in conjunction with zinc (II) salts to...

OBJECTIVE To study the effects of zinc supplementation on malaria and other causes of morbidity in young children living in an area holoendemic for malaria in west Africa. DESIGN Randomised, double blind, placebo controlled efficacy trial. SETTING 18 villages in rural northwestern Burkina Faso. PARTICIPANTS 709 children were enrolled; 685 completed the trial. INTERVENTION Supplementatio...

The rate of copper II/zinc cementation from copper sulphate solutions in the absence and in the presence of methanol (CH3OH) and dimethyl sulphoxide (DMSO) has been studied and the reaction was found to follow first-order kinetics. The influence of several parameters on the course of the reaction, such as cylinder rotation speed, initial concentration of Cu ions, temperature and concentration o...
