Allergic contact dermatitis (ACD) is a delayed-type hypersensitivity (DTH) reaction induced by repeated contact with sensitizers. The ability of a chemical to act as a sensitizer has most frequently been tested in animals. As the use of animals for these purposes is gradually and globally being phased out, there is a need for reliable in vitro surrogate assays. Currently proposed in vitro assays are designed to test four key events of the adverse outcome pathway (AOP) involving covalent modification of self-proteins by sensitizers (haptenation) and presentation of new antigens (hapten/carrier complexes) to the immune system...

Cerebral lateralization, the partitioning of functions into a certain hemisphere of the brain, is ubiquitous among vertebrates. Evidence suggests that the cognitive processing of a stimulus is performed with a specific hemisphere depending in part upon the emotional valence of the stimulus (i.e. whether it is appetitive or aversive). Recent work has implicated a predominance of right-hemisphere processing for aversive stimuli. In fish with laterally placed eyes, the preference to view an object with a specific eye has been used as a proxy for assessing cerebral lateralization...

BACKGROUND: Lymphoproliferative disease often presents the clinician and pathologist with a diagnostic dilemma, particularly in the early course of the disease. METHODS: We used modified BIOMED-2 protocols to detect monoclonal expansions of immunoglobulin heavy chain (IgH) and T-cell receptor (TCR) genes in 957 formalin-fixed paraffin-embedded samples from 717 patients. To eliminate false-positive results, heteroduplex analysis was used after PCR reactions. The impact of different fixatives on DNA quality and performance of PCR was assessed...

African black-footed cats (Felis nigripes) are endangered wild felids. One male and full-sibling female African black-footed cat developed vision deficits and mydriasis as early as 3 months of age. The diagnosis of early-onset progressive retinal atrophy (PRA) was supported by reduced direct and consensual pupillary light reflexes, phenotypic presence of retinal degeneration, and a non-recordable electroretinogram with negligible amplitudes in both eyes. Whole genome sequencing, conducted on two unaffected parents and one affected offspring was compared to a variant database from 51 domestic cats and a Pallas cat, revealed 50 candidate variants that segregated concordantly with the PRA phenotype...

The interaction of motorists and bicyclists, particularly during passing maneuvers, is cited as one of the primary causes of bicyclist fatalities. This paper reports the results of a driving simulator study, which sought to analyze the effects that three cross-section configurations of a two-lane rural road and four geometric elements of the road have on driver behavior, during the interaction with a cyclist. A two-lane rural road, about 11km long, was designed and implemented in an advanced-interactive driving simulator...

In a fluctuating environment, the optimal level of exploratory behavior depends on the proportion of current risks and benefits. The exploratory behavior is, therefore, often subjected to heterogenous selection. In populations of commensal rodents living in close proximity of humans, this pressure is further increased by pest management. We hypothesize that the black rat (Rattus rattus) responds to this pressure by either high behavioral flexibility or by development of personality types. The aim of this study was to analyze exploratory behavior and boldness of wild black rats and its changes over time to determine whether exploratory behavior is a personality trait in black rats...

The genus Neofusicoccum includes species with wide geographical and plant host distribution, some of them of economic importance. The genus currently comprises 27 species that are difficult to identify based on morphological features alone. Thus, species differentiation is based on phylogenetic species recognition using multigene genealogies. In this study, we characterised the mating type genes of Neofusicoccum species. Specific primers were designed to amplify and sequence MAT genes in several species and a PCR-based mating type diagnostic assay was developed...

BACKGROUND: Becker muscular dystrophy (BMD) is an X-linked recessive disorder affecting about 1:18,000 male births. Female carriers are usually asymptomatic, but 2.5-18% may present muscle or heart symptoms. In the present work the role of the X chromosome inactivation (XCI) on the onset of symptoms in BMD carriers was analysed and compared with the pattern observed in Duchenne muscular dystrophy (DMD) carriers. METHODS: XCI was determined on the lymphocytes of 36 BMD carriers - both symptomatic and not symptomatic - from 11 families requiring genetic advice at the Cardiomyology and Medical Genetics of the Second University of Naples, through the AR methylation-based assay...

AIMS: The 2013 CAP/IASLC/AMP guideline for EGFR and ALK testing in lung carcinoma indicates that either the primary tumor or the metastasis is suitable for testing. The heterogeneity of gene mutations has been extensively studied, while similar reports on gene rearrangements are limited. The aim of this study was to determine if ALK status between primary tumor and matched metastasis differs. METHODS AND RESULTS: 15 ALK-FISH rearranged and 19 non-ALK-FISH rearranged adenocarcinomas were retrospectively collected based on availability of tissue from a matched metastatic site...
