The limited number of studies reporting emotional memory impairments in adults with psychopathic traits has not yet been replicated in conduct disordered adolescents with callous unemotional (CU) traits. This study aimed to test the developmental hypothesis that emotional memory will also be impaired in conduct disordered adolescents with CU traits on similar memory tasks. Eighty-four conduct d...

Little is known about the importance of trade-offs between ageing and other life history traits, or the effects of ageing on sexual selection, particularly in wild populations suffering high extrinsic mortality rates. Life history theory suggests that trade-offs between reproduction and somatic maintenance may constrain individuals with higher initial reproductive rates to deteriorate more rapi...

A primary goal of polygenic scores, which aggregate the effects of thousands of trait-associated DNA variants discovered in genome-wide association studies (GWASs), is to estimate individual-specific genetic propensities and predict outcomes. This is typically achieved using a single polygenic score, but here we use a multi-polygenic score (MPS) approach to increase predictive power by exploiti...

Anurans (frogs and toads) are unique among land vertebrates in possessing a free-living larval stage that, parallel to adult frogs, diversified into an impressive range of ecomorphs. The tempo and mode at which tadpole morphology evolved through anuran history as well as its relationship to lineage diversification remain elusive. We used a molecular phylogenetic framework to examine patterns of...

Historical geological events and climatic changes are believed to have played important roles in shaping the current distribution of species. However, sympatric species may have responded in different ways to such climatic fluctuations. Here we compared genetic structures of two corvid species, the Azure-winged Magpie Cyanopica cyanus and the Eurasian Magpie Pica pica, both widespread but with ...

BACKGROUND Cholecystocentesis can be part of the diagnostic workup of hepatobiliary disease in small animals, but literature on cytological evaluation of bile is scant. OBJECTIVES To determine the diagnostic utility of cytological assessment of bile aspirates. ANIMALS Fifty-six and 78 client-owned dogs and cats, respectively, with bile collected by cholecystocentesis and submitted to our di...

BACKGROUND/AIM The Epi proLung® BL Reflex Assay [short stature homeobox gene two methylation assay (SHOX2 assay)] (Epigenomics AG, Berlin, Germany) utilizes quantitative methylation-sensitive real-time polymerase chain reaction (QMSP) for the quantification of methylated short stature homeobox gene two (SHOX2) DNA. In the present study, the diagnostic utility of the SHOX2 assay was tested with ...

AIM To determine interobserver and intra-observer agreement in the assessment of cytological grade and intraduct necrosis in pure duct carcinoma in situ (DCIS) of the breast. METHODS Sixty unselected cases with illustrated diagnostic criteria were circulated to 19 practising histopathologists. RESULTS Overall agreement was moderate for cytological grade in three categories: 71% agreement; w...

Background & Objective: Modified Ultra-fast Papanicolaou (MUFP) stain has been developed from Papanicolaou stain (PAP) with the...

Manipulation of host reproduction and efficient maternal transmission have facilitated the global spread of Wolbachia through millions of insect species. Cytological studies of the most common Wolbachia-induced phenotype, cytoplasmic incompatibility (CI), demonstrate that Wolbachia induce CI by altering host cell cycle timing. Cytological analyses also suggest that microtubules and motor protei...
