Parasitic infectious agents in endemic African countries including Tanzania rarely occurs in isolation and co-infections within a single host in populations are norms rather than exceptions (Brooker et al., 2007; Mazigo et al., 2010a; Mboera et al., 2011). Coinfection refers to a situation in which an individual harbours two or more infections from different species simultaneously, where as mon...

Parasitic infection can modify host mobility and consequently their dispersal capacity. We experimentally investigated this idea using the ciliate Paramecium caudatum and its bacterial parasite Holospora undulata. We compared the short-distance dispersal of infected and uninfected populations in interconnected microcosms. Infection reduced the proportion of hosts dispersing, with levels differi...

Background. Orally ingested medications now come in both immediate release and controlled release preparations. Controlled release preparations were developed by pharmaceutical companies to improve compliance and decrease frequency of pill ingestion. Case Report. A 67-year-old obese male patient presented to our clinic with focal abdominal pain that had been present 3 inches below umbilicus for...

Cannabis use has often been associated with various forms of psychosis. Today it is well established that everyone produces marijuana-like compounds known as endocannabinoids. The endocannabinoid system is a homeostatic regulator of all body systems including the nervous system. As a result, imbalances in the endocannabinoid system have been considered as possible causes of various forms of men...

Recently, there has been a concerted research effort by marine scientists to quantify the sensitivity of marine organisms to ocean acidification (OA). Empirical data generated by this research have been used to predict changes to marine ecosystem health, biodiversity and productivity that will be caused by continued acidification. These studies have also found that the effects of OA on marine o...

A s ín d r o m e q u e a c o m p a n h a a hiperimunoglobulinemia E (hiper-IgE), como descrita originalmente por Buckley e cols2 em 1972, consistia de susceptibilidade aumentada a infecções, particularmente por estafilococos, e n ív e is s é r ic o s de IgE e x tre m a m e n te elevados (> 2000ng/ml). Demostrou-se a seguir que estes indivíduos também apresentavam deficiência na quimiotaxia neut...

The root parasitic plant species Phelipanche ramosa, branched broomrape, causes severe damage to economically important crops such as tomato. Its seed germination is triggered by host-derived signals upon which it invades the host root. In tomato, strigolactones (SLs) are the main germination stimulants for P. ramosa. Therefore, the development of low SL-producing lines may be an approach to co...
