Water deficit and phosphate (Pi) deficiency adversely affect growth and biological nitrogen fixation (BNF) of legume crops. In this study, we examined the impact of interaction between soil water conditions and available soil-Pi levels on growth, nodule development and BNF potential of nine cowpea varieties grown on dry savanna soils. In our experimental design, soils with different available s...

An established goal of WHO and its member states is that all people, whatever their stage of development and their social and economic conditions have the right to have access to an adequate supply of safe drinking water (WHO, 1986, 1996, 1997). Water is considered one of the most important and sensitive issues in the Middle East, where increasing water deficiency and deterioration of the avail...

We assessed the nutrient (N, P) deficiency of phytoplankton from the perennially ice-covered lakes in Taylor Valley, Antarctica, with 14C-based bioassays. Phytoplankton in the near-surface waters from three of the four lakes displayed elevated photosynthetic carbon assimilation in the presence of added P relative to controls. Carbon assimilation in samples from deep chlorophyll layers was also ...

Normal subjects and patients with antidiuretic hormone (ADH) deficiency were studied to determine the mechanism of the antidiuretic action of clofibrate. Before clofibrate treatment, the patients' ability to concentrate urine with a standardized dehydration procedure correlated with the amount of ADH which was excreted. During clofibrate administration all six patients with ADH deficiency devel...

From November 1979 to May 1982, I had the "honor" of serving time at Evin political prison, Teheran Iran. Evin is the historical prison which has set the pace of revolution in the country. At Evin it was discovered that increased regular intake of water improved the clinical picture of peptic ulcer disease. One of the main components of this picture was pain of varying severity, sometimes very ...

The nutritional status of 80 patients with non-alcoholic chronic liver disease was assessed by determination of various nutritional parameters in body fluids. With the exception of vitamin C there was a higher incidence (40%) of fat soluble vitamin deficiency (vitamins A, E, and carotene) than of the water soluble vitamins. Less than 10% of patients showed evidence of vitamin B12, nicotinic aci...
