OBJECTIVE To explore the food intake of young migrants living in Germany. DESIGN Children and adolescents aged 0 to 17 years living in Germany, including 17.1 % with a migration background, were examined in a representative health survey. Food frequency data of 7186 boys and 6919 girls, aged 3 to 17 years, were analysed separately for Turkish, Russian Germans, other migrants and non-migrants....

The infective stage of Haemonchus contortus, the third-stage larva, retains the secondstage larval cuticle. Exsheathment takes place in the rumen of the host (Somerville, 1954), under the influence of a number of factors, chiefly unionized carbonic acid and dissolved gaseous carbon dioxide (Rogers, 1960). The ensheathed larva survives desiccation, but, if caused to exsheathe by appropriate trea...

The dauer larva of the nematode Caenorhabditis elegans is a good model system for investigating the regulation of developmental fates by environmental cues. Here we show that SDF-9, a protein tyrosine phosphatase-like molecule, is involved in the regulation of dauer larva formation. The dauer larva of sdf-9 mutants is different from a normal dauer larva but resembles the dauer-like larva of daf...

The forkhead gene FH1 encodes a HNF-3beta protein required for gastrulation and development of chordate features in the ascidian tadpole larva. Although most ascidian species develop via a tadpole larva, the conventional larva has regressed into an anural (tailless) larva in some species. Molgula oculata (the tailed species) exhibits a tadpole larva with chordate features (a dorsal neural senso...

BACKGROUND Studies on migration often ignore the health and social impact of migrants returning to their rural communities. Several studies have shown migrants to be particularly susceptible to HIV infection. This paper investigates whether migrants to rural households have a higher risk of dying, especially from HIV, than non-migrants. METHODS Using data from a large and ongoing Demographic ...

here are currently at least 85 million rural-urban migrants in the mainland China. These migrants face great health risks, yet are not recognised or covered by any medical care scheme. This paper demonstrates that the key issue for migrants’ health is not their social characteristics such as low income or the lack of health awareness, as most literature has emphasised, but lies in the instituti...

The preimaginal stages including egg, mature larva and pupa of Pseudaspidapion botanicum Alonso-Zarazaga & Wang, 2011 were described and figured, diagnostic characters of larva and pupa were discussed, and corresponding biological information was supplied. The nomenclature of frontal setae in the larva compared with curculionid weevils, the absence of the hypopharyngeal bracon in the larva, and...

background: gnathostoma spinigerum causes larva migran in human which is endemic in southeast asia. information regarding larva migration is limited. in this study, we investigated the parasite migra­tion by recovery of worms from the whole body of mouse after oral infection with advanced third stage larvae (al3). the percentage of blood eosinophils was examined in parallel. methods: mice were ...

background : the visceral larva migrans (vlm) is a syndrome observed in human infection with helminth larval eggs such as the toxocara spp. that usually infects dogs and cats. among the risk factors involved in the occurrence of vlm, partic­ularly importance of these animal populations, an investigation was carried out for the presence of toxocara spp. eggs in public parks in the city of urmia,...
