background: the prevalence and intensity of soil-transmitted helminth infections and the anthropogenic risk factors of 978 ran­domly selected primary school children from igbede community in isoko south local government area of delta state southern nigeria were evaluated. methods: subjects were screened for the presence of sth using direct smear method and kato-katz techniques. this study was c...

according to general circulation model (gcm), zonal thermal belts are 1- inter-tropical convergence zones (itcz) around eqator; 2- sub tropical high (sth) belt around 30 degree latitude; 3- sub polar low (spl) belt around high latitudes. the belt of inter-tropical convergence zone (itcz) displaces in meridional path, about 5° over the oceans and up to 40° over continents, during the seasons of ...

Soil-transmitted helminth (STH) infections and zinc deficiency are often found in low- and middle-income countries and are both known to affect child growth. However, studies combining data on zinc and STH are lacking. In two studies in schoolchildren in Cuba and Cambodia, we collected data on height, STH infection and zinc concentration in either plasma (Cambodia) or hair (Cuba). We analyzed w...

BACKGROUND >94% of new annual leprosy cases are diagnosed in populations co-endemic for soil-transmitted helminths (STH). STH can profoundly dysregulate host immune responses towards Th2 bias, which can be restored over time after deworming. We hypothesize that STH co-infection is associated with leprosy reaction (denoted as simply "reaction" herein) occurrence within a co-endemic population. ...

We study the complexity of approximating the Stieltjes integral R 1 0 f (x) dg(x) for functions f having r continuous derivatives and functions g whose sth derivative has bounded variation. Let r(n) denote the nth minimal error attainable by approximations using at most n evaluations of f and g, and let comp(") denote the "-complexity (the minimal cost of computing an "-approximation). We show ...

Let r(n) denote the nth minimal error attainable by approximations using at most n evaluations of f and g, and let comp(ε) denote the ε-complexity (the minimal cost of computing an ε-approximation). We show t...

Intracellular recordings were made from dopaminergic neurons of the rat substantia nigra compacta (SNc) in in vitro slice preparations to study the synaptic influence from the subthalamic nucleus (STh). After microstimulation of STh, monosynaptic excitatory postsynaptic potentials (EPSPs) were produced in dopaminergic neurons. STh-induced EPSPs were composed of 6-cyano-7-nitroquinoxalene-2,3-di...
