objective: the role of wnt signaling and its antagonist; secreted frizzled related protein type 4 (sfpr4) was reported in rodent ovarian follicular development. this study examines immunolocalization of sfrp4 in ovaries of polycystic ovary (pco) rat model and evaluates its role in follicular growth arrest and its premature differentiation. materials and mathods: pco was induced with daily admin...

In this issue of Neuron, Duan et al. (2015) introduce a novel rodent model of executive control. Their neural recordings provide direct evidence for the task-set inertia theory and suggest a crucial role for the superior colliculus in executive control.

Strategies for the prevention and control of commensal rodents would improve with better knowledge their response to environmental factors from different spatial scales. In this research we evaluated which scales characteristics determine rodent infestation levels in a subtropical urban rural landscape gradient Misiones, Argentina. A total 87 households an urban, periurban were surveyed at leas...

1. The screening for potential anti-malaria properties by bioassay guided fractionations. The biological properties were carried out using the plasmodium lactate dehydrogenase assay (pLDH) (Makler, 1993). 2. The harmful effect of the extract was determined by the MTT assay (Mossman, 1983). 3. The extracts were tested for its efficacy in animal model using rodent malaria parasite, P. berghei usi...

Abstract Background Rodent malaria parasites are important models for studying host-malaria parasite interactions such as host immune response, mechanisms of evasion killing, and vaccine development. One the rodent is Plasmodium yoelii , multiple P. strains or subspecies that cause different disease phenotypes have been widely employed in various studies. The genomes transcriptomes several anal...

In response to this, an Australian Centre for International Agricultural Research (ACIAR) project titled “Farmer-based Adaptive Rodent Management, Extension and Research System in Cambodia” (referred to as the FARMERS project in this paper) has been trialing a physical method of rodent control called the Community Trap Barrier System or TBS (ACIAR 2001). TBS consists of a lure crop and trapping...

The mammalian and flea fauna of La Rioja Province is one of the least known from northwestern Argentina. In this study, the distribution and nomenclature of 13 species of fleas of bats and rodents from La Rioja Province are updated. Four species of fleas are recorded for the first time in La Rioja Province including a new record for northwestern Argentina, and two new flea-host associations. An...
