objective: duplex ultrasonography is a non-invasive, non-expensive screening test for carotid disease. intima media thickness (imt) is appropriate for atherosclerosis process diagnosis. leukoaraisis (la) increase the risk of cerebrovascular accident (cva). la patients need preventive medication for cva. imt is a non-invasive diagnostic and prognostic test in la. the aim of this study was evalua...

To test whether sex determination in the parasitic wasp Bracon sp. near hebetor (Hymenoptera: Braconidae) is based upon a single locus or multiple loci, a linkage map was constructed using random amplified polymorphic DNA (RAPD) markers. The map includes 71 RAPD markers and one phenotypic marker, blonde. Sex was scored in a manner consistent with segregation of a single "sex locus" under comple...

Ecoimmunology conceptualizes the role of immunity in shaping life history a natural context. Within ecoimmunology, macroimmunology is framework that explains effects habitat and spatial differences on variation immune phenotypes across populations. these frameworks, ontogeny—the development system an individual span—has received little attention. Here, we investigated how ontogeny from birth un...

An individual's sex depends upon its genes (genotypic sex determination or GSD) in birds and mammals, but reptiles are more complex: some species have GSD whereas in others, nest temperatures determine offspring sex (temperature-dependent sex determination). Previous studies suggested that montane scincid lizards (Bassiana duperreyi, Scincidae) possess both of these systems simultaneously: offs...

OBJECTIVES This study examines sex differences in vulnerability among children experiencing rapid culture change that may reflect distinct microecologies driven by differential parental investment and/or sex-specific life history strategies. Apparent female growth canalization may be a life history strategy favoring growth over maintenance but also may reflect sex-differentiated selection for r...
