Conroy, R. T. W. L., Elliott, A. L., and Mills, J. N. (1970). Brit. J. industr. Med., 27, 356-363. Circadian excretory rhythms in night workers. Urine samples have been collected from day and night shift workers in a light engineering factory over periods of 24 or 48 hours during which blood was also collected for determination of plasma 11-hydroxycorticosteroids (11-OHCS). Different subjects d...

Although the belief is widely held that a high protein diet is deleterious to the hypertensive patient, a careful survey of the literature discloses that this is not a generally substantiated point of view. Some clinicians (1-4) in particular Newburgh (5), have insisted that the withdrawal of protein from the diet of patients with hypertension results in the reduction of their blood pressure an...

Glycan molecules from helminth parasites have been associated with diverse biological functions ranging from interactions with neighbouring host cell populations to down-modulation of specific host immunity. Glycoproteins secreted by the intestinal nematode Heligmosomoides polygyrus are of particular interest as the excretory-secretory products (termed HES) of this parasite contain both heat-la...

The excretory system of the nematode Caenorhabditis elegans is a superb model of tubular organogenesis involving a minimum of cells. The system consists of just three unicellular tubes (canal, duct, and pore), a secretory gland, and two associated neurons. Just as in more complex organs, cells of the excretory system must first adopt specific identities and then coordinate diverse processes to ...

Nuclear receptors of the Hepatocyte Nuclear Factor-4 (HNF4) subtype have been linked to a host of developmental and metabolic functions in animals ranging from worms to humans; however, the full spectrum of physiological activities carried out by this nuclear receptor subfamily is far from established. We have found that the Caenorhabditis elegans nuclear receptor NHR-31, a homolog of mammalian...

excretory/secretory antigen was prepared by culturing live adult worms of haemonchus contortus in rpmi 1640 medium at a concentration of 50 worms per ml in a culture-flask at 37 ˚c for 24 hr and the culture supernatant was used as antigen. the e/s antigen was purified by thiol-sepharose affinity chromatography. on western blot analysis, it was demonstrated that thiol-purified antigen showed a s...

background : immunological response of host and parasite play a key role in developing vaccina­tion and immunization. the present study deals with the immune response and effecter mechanism, which was confirmed by migration inhibition factor (mif).  methods : the present work was conducted in parasitological lab of postgraduate department of zool­ogy, government holkar science college, indore (...

background: ornithobilharziosis as one of the parasitic infections may give rise to serious economic problems in animal husbandry. the aim of the study was to prepare and compare the somatic and excretory-secretory (es) antigens of o. tur­kestanicum in gel diffusion test. methods: excretory-secretory (es) and somatic antigens of ornithobilharzia turkestanicum were prepared from collected worms ...
