In eukaryotes, many independent evolutionary transitions have been documented between hermaphroditic sexual systems and separate sexes (which is termed dioecy in plants and gonochorism in animals)1. Dioecious plants or gonochoristic animals are characterised by individuals of the same species but with...
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.Populations across the world are aging at a surprising pace, bringing potentially big...

Some may have a single set of reproductive structures, be unsegmented or lack well-defined segmentation. The basic synapomorhic, shared traits are the absence of digestive tract and the presence of microtriches on the tegumental surface (Caira and Littlewood, 2001; Lockyer et al., 2003). ...
摘要: Reports that forest researchers have developed an innovative method of using nematodes to control the infestation of the forests by the pine weevil. Bane of trees planted on restocked conifer sties; Application of nematodes on the stumps of trees; Tests undertaken in Wales and Scotland....
We have used these data to identify gene families and processes associated with the major parasitic groups. To accelerate the search for new interventions, we have mined the dataset of more than 1.4 million genes to predict new drug targets and drugs. Results Genomic diversity in parasitic ...
Such reductions in worm fecundity post treatment suggest that egg - based measures of drug efficacy, such as Kato-Katz, may overestimate the short-term effect of praziquantel on adult - worm burdens. These findings have important implications forS. mansonitransmission control, diagnostic protocols, ...
medinensis) indicate we still have much to learn about these parasites. Furthermore, among eight species in the Old World and six species in the New World there is a lack of general life history knowledge as well as questions on species occurrence, host diversity, and transmission dynamics. ...
even low doses of praziquantel significantly reduced adult-worm fecundity.Such reductions in worm fecundity post treatment suggest that egg-based measures of drug efficacy,such as Kato-Katz,may overestimate the short-term effect of praziquantel on adult-worm burdens.These findings have important ...
