Species of tapeworms belonging to the family Taenidae are among the most important helminth parasites of man and domestic animals. Taeniasis and cysticercosis are serious problems of public health and economy in developing countries. The ultimate control of these diseases depends on the development of effective prophylactic vaccines. Although vaccines against bacterial and viral infections are ...

A novel fiber-optic electrochemiluninescence sensor has been developed. It can be conveniently applied by placing into the sample solution in a manner similar to a conventional ion selective electrode, without requiring liquid luminous reagent and a flowing system. The sensor is consisted of an independent probe and a case for exclusion the ambient light, allowing the sample solution to pass th...

To show the impact of sensor behaviour on the control result, four strategies for aeration control are tested using different sensor characteristics. It is demonstrated, on the one hand, how an increasing response time will limit the achievable control quality and, on the other hand, how a given sensor characteristic can be taken into account for the controller design. The presented tests show ...

Leptin, a recently identified hormonal product of the ob gene, is known to regulate appetite, body metabolism, and reproductive functions. We investigated the expression of the leptin receptor (Ob-R) in testes from different age groups. The messenger RNA for Ob-R was found in testes from all age groups using RT-PCR. Using immunohistochemistry, we observed age- and stage-dependent distribution o...

Accumulation of protein-bound uraemic toxins (PBUTs) is one of the reasons for the development of uraemia-related complications including cardiovascular disease; however, conventional haemodialysis is limited in its ability to remove PBUTs. We aimed to examine whether the oral charcoal adsorbent AST-120 has an additive effect on PBUT removal in haemodialysis patients. During the 4-week study, a...

The response of 73 psychiatric outpatients to manipulation of their dietary intake of carbohydrate was studied with respect to symptoms of anxiety, depression, and dys-perception. In particular these symptoms were evaluated in three conditions: in ketosis, at the transition point from ketosis to non-ketosis, which I regard as an "Optimum Carbohydrate Level" (OCL), and at a higher carbohydrate i...

In Wistar rats infected with 500 to 2,500 Trichinella spiralis larvae the muscle larvae intensity (larvae per gram-l.p.g.) was measured from 20 to 180 day post infection (d.p.i). The l.p.g. increased to day 40-50 p.i. and decreased thereafter. The highest reduction took place between 60 and 120 d.p.i. with intermediate inoculum of T. spiralis larvae. The mechanism of the reduction of T. spirali...

The microsomal synthesis of docosahexaenoic acid (DHA) from radiolabeled eicosapentaenoic acid was tested in vitro using the livers of crab-eating monkeys. The test animals included 1 fetus (embryonic day 120), 2 neonates (full-term, embryonic day 165), and 2 adults. DHA was formed equally in the liver microsomes of each animal. Neonatal livers were found to contain higher percent of arachidoni...

Goniothalamin was evaluated for its anti-malaria activity in-vivo, using the 4-Day Suppressive Test (Peters & Robinson, 1975). The test were carried out against two strains of rodent malaria parasites, the sensitive strain P. berghei ANKA (MRA 311) strain and the resistant strain P. yoelii (MRA 312). An Initial screening was carried out using a single dose of 10 mg/kg body weight administered s...
