Limited information is available on suitable height of transport crates for turkeys. We compared behaviors and physiological indicators of four groups of 10 female turkeys each confined in either conventional (38.5 cm height) or experimental (77 cm height) crates during six commercial pre-slaughter transportations for 86 km (76 ± 4 min) along two tracts with one-lane streets, crossroads, bends, roundabouts (S1 and S2) and a highway tract (H) between S1 and S2. Only 36% of birds in the higher crates maintained a standing position...

In the framework of a gene flow assessment, we investigated the natural hybridization rate between Gossypium hirsutum (AADD genome) and G. herbaceum (AA genome). The latter species, a diploid progenitor of G. hirsutum, is spontaneously present in South Africa. Reciprocal crosses were performed without emasculation between G. herbaceum and G. hirsutum Neither examination of the morphological characteristics nor flow cytometry analysis of the 335 plants resulting from the G. hirsutum x G. herbaceum cross showed any hybrid features...

White matter injury (WMI) of prematurity is associated with a spectrum of neurological disorders ranging from mild cognitive and behavioral deficits to cerebral palsy. Translational studies have implicated impaired oligodendrocyte development after hypoxia as the primary cause of WMI, but the underlying mechanisms remain poorly understood. The goal of this study was to identify alterations in the expression of oligodendrocyte precursor cell transcription factors in a mouse model of transient mild global hypoxia...

Learning via instructions and learning through physical practice are complementary pathways to obtain skilled performance. Whereas an initial task representation can be formed on the basis of instructions, physically practicing novel instructions leads to a shift in processing mode from controlled processing toward more automatic processing. This shift in processing mode is supposedly caused by the formation of a pragmatic task representation, which includes task parameters needed to attain skilled task execution...

The concentrations of water-soluble compounds (ions, carboxylic acids, amino acids, sugars, phenolic compounds) in aerosol and snow have been determined at the coastal Italian base "Mario Zucchelli" (Antarctica) during the 2014-2015 austral summer. The main aim of this research was to investigate the air-snow transfer processes of a number of classes of chemical compounds and investigate their potential as tracers for specific sources. The composition and particle size distribution of Antarctic aerosol was measured, and water-soluble compounds accounted for 66% of the PM10 total mass concentration...

A novel series of hybrid molecules (5a-5m) was designed, synthesized and evaluated as multifunctional cholinesterase (ChE) inhibitors against cognitive dysfunction. Heterocyclic moieties acridine and piperazine were conjugated with suitable linkers in a single scaffold and the structures of the target compounds were confirmed by IR, (1) H NMR, (13) C NMR and LC-MS analysis. The pharmacological activity of synthesized compounds was evaluated using behavioral models of amnesia viz. step down passive avoidance and elevated plus maze at a dose 0...

Aggression jeopardizes positive development in children and predicts social and academic maladjustment in school. The present study determined the relationships among anger dysregulation (a marker of emotion regulation), cortisol activity (a biomarker of stress), and peer-nominated aggression in typically developing children in their everyday classroom setting (N = 151, Mean age = 10.86, SD =.74). Salivary cortisol was collected at 09:15, 11:45, and 14:45 hr across 4 consecutive days. Children provided self-reports of anger regulation; peers reported proactive and reactive aggressive behaviors...

Traumatic brain injury (TBI) initiates a deleterious inflammatory response that exacerbates pathology and worsens outcome. This inflammatory response is partially mediated by a reduction in cAMP and a concomitant upregulation of cAMP-hydrolyzing phosphodiesterases (PDEs) acutely after TBI. The PDE4B subfamily, specifically PDE4B2, has been found to regulate cAMP in inflammatory cells, such as neutrophils, macrophages and microglia. To determine if PDE4B regulates inflammation and subsequent pathology after TBI, adult male Sprague Dawley rats received sham surgery or moderate parasagittal fluid-percussion brain injury (2 ± 0...

Switching between tasks is assumed to be accompanied by inhibiting currently irrelevant, but competing tasks. A dominant task that strongly interferes with performing a weaker task may receive especially strong inhibition. We tested this prediction by letting participants switch among three tasks that differ in dominance: a location discrimination task with strong stimulus-response bindings (responding with left-hand and right-hand button presses to stimuli presented left or right to the fixation cross) was combined with a color/pattern and a shape discrimination task, for which stimulus-response mappings were arbitrary (e...

Few studies have investigated the effects of iron oxide nanoparticles (NPs) on analgesia. We developed inflammatory pain models via complete Freund's adjuvant injection over the hind paw in CD1 mice. Various doses of magnetite (Fe3O4) NPs were injected into the paw. Analgesia behavior was checked with von Frey microfilament and thermal irradiation measurements. Paw skin tissues were harvested at the maximal analgesia time point. The presence of activated white cells (CD68, myeloperoxidase) and free radical (reactive oxygen species, ROS) production were also checked...

Studying isolation by distance can provide useful demographic information. To analyze isolation by distance from molecular data, one can use some kind of genetic distance or coalescent simulations. Molecular markers can often display technical caveats, such as PCR-based amplification failures (null alleles, allelic dropouts). These problems can alter population parameter inferences that can be extracted from molecular data. In this simulation study, we analyze the behavior of different genetic distances in Island (null hypothesis) and stepping stone models displaying varying neighborhood sizes...

Brain angiogenesis inhibitor protein 3 (BAI3) is from the adhesion group of seven-transmembrane spanning G protein-coupled receptors (GPCRs) and has been identified via gene expression profiling as being upregulated in small-cell lung cancer (SCLC) tumors. It has subsequently been validated as a sensitive and specific immunohistochemical marker for SCLC, helping to differentiate these tumors from morphologically similar large-cell neuroendocrine (LCNEC) malignancies. It is, however, still unclear as to the role BAI3 proteins might play in SCLC and indeed how they might contribute to tumorigenesis...

Epithelial-free areas, present in both thymic cortex and medulla, have been studied in WT and EphB-deficient mice that have important alterations in the development of thymic epithelium due to the lack of proper thymocyte-thymic epithelial cell interactions. In both WT and mutant thymuses, the number and size of epithelial-free areas are significantly larger in the medulla than in the cortex. The two parameters show a reverse correlation: low numbers of these areas course with large epithelial-free areas and vice versa...

AIM: Remote ischemic Post Conditioning (RIPOC) has shown to be neuroprotective against cerebral Ischemic Reperfusion (I/R) injury. However, the RIPOC protection against I/R injury induced cognitive abnormalities still remains elusive. Abundant evidence from earlier studies highlighted the role of heme oxygenase-1 (HO-1) in neuronal survival in various neurodegenerative disorders. Thus, in the present study, we investigated the possible contribution of HO-1 in RIPOC mediated neuroprotection against cerebral I/R injury and associated cognitive deficits...

The World Health Organization (WHO) classification of central nervous system (CNS) tumors was revised in 2016 with a basis on the integrated diagnosis of molecular genetics. We herein provide the guidelines for using molecular genetic tests in routine pathological practice for an accurate diagnosis and appropriate management. While astrocytomas and IDH-mutant (secondary) glioblastomas are characterized by the mutational status of IDH, TP53 , and ATRX , oligodendrogliomas have a 1p/19q codeletion and mutations in IDH, CIC , FUBP1 , and the promoter region of telomerase reverse transcriptase ( TERTp )...

Tumor recurrence in glioblastoma (GBM) is, in part, attributed to increased epithelial-to-mesenchymal transition (EMT) and enhanced tumor cell dissemination in adjacent brain parenchyma after ionizing radiation (IR). EMT is associated with aggressive behavior, increased stem-like characteristics and treatment resistance in malignancies; however, the underlying signaling mechanisms that regulate EMT are poorly understood. We identified grade-dependent p21-activated kinases 4 (PAK4) upregulation in gliomas and further determined its role in mesenchymal transition and radioresistance...

BACKGROUND AND AIMS: Sending and receiving sexually suggestive or explicit images or texts (sexting) have been shown to be associated with health risk behaviors but literature about this phenomenon is scarce in Nigeria. This study looked at the prevalence, predictors, and associated sexual risk behaviors of sexting among postsecondary school young persons in Ibadan, Nigeria. METHODS: This was a cross-sectional study using a self-administered questionnaire. Data were obtained for sociodemographic characteristics and sexual orientation, sexting behavior, personality assessment (using the International Personality Item Pool Big-Five factor markers), indicators for problematic phone use (using Mobile Phone Problem Use Scale), and sexual behavior...

The role of serotonin (5-hydroxytryptamine, 5-HT) in social behavior regulation is not fully understood. While 5-HT release in nuclei of the social behavior network has generally been associated with inhibition of aggressive behavior across multiple classes of vertebrates, less is known about its effects on sexual, especially non-copulatory courtship display behaviors. Furthermore, most research has examined effects at 5-HT release sites, while studies examining the behavioral relevance of source cell populations have generated contradictory findings...

We investigated kin relatedness and kin-recognition abilities of the Argentine ant, Linepithema humile (Mayr), an invader from North America that has pervaded Japan for 20 yr, using genetic analyses and behavioral bioassays. From these data and interactions among factors, we formulated an eradication and management time-scale pattern diagram. Relatedness within a colony using microsatellite markers was effectively zero, whereas relatedness estimated by multilocus DNA fingerprinting markers was relatively high...
