Anxiety symptoms occur in a large portion of Alzheimer's disease (AD) patients. ApolipoproteinE-4 (ApoE ε4 allele), a risk factor for AD, has been recognized as an important contributor to psychiatric disorders. In the present study, we aimed to investigate the corticosterone level in relation to anxiety-like behavior changes in transgenic male mice with different glial fibrillary acidic protein (GFAP)-ApoE isoforms. GFAP-ApoE4 transgenic mice aged 3 months showed higher anxiety-like behavior in open field, light-dark box and elevated plus maze tasks compared with that of age-matched GFAP-ApoE3 mice...

We discuss the governing forces for analytics, especially concerning citizens' behaviours and their transactions, that depend on which of three spheres of operation an institution is in (corporate, public sector/government and academic). We argue that aspirations and missions also differ by sphere even as digital spaces have drawn these spheres ever closer together. We propose that citizens' expectations and implicit permissions for any exploitation of their data require the perception of a fair balance of benefits, which should be transparent (accessible to citizens) and justifiable...

Chemotherapy is a standard strategy for glioma, while chemoresistance remains a major therapeutic challenge in current clinical practice. Our present study was aimed to determine whether inhibition of the miR-223/ paired box 6 (PAX6) pathway could increase the sensitivity of glioma to Temozolomide. An elevated level of miR-223 was observed in glioma tissues. Exogenous miR-223 promoted cell survival when exposed to Temozolomide (TMZ), while miR-223 inhibition could reverse this process. The RNA and protein levels of PAX6 were significantly decreased by exogenous miR-223, and the 3'-untranslated region of PAX6 was shown to be a target of miR-223...

Life is uncertain. To reduce uncertainty and make adaptive decisions, individuals need to collect information. Individuals often visit the breeding sites of their conspecifics (i.e., "prospect"), likely to assess conspecifics' reproductive success and to use such information to identify high-quality spots for future breeding. We investigated whether visitation rate by prospectors and success of visited sites are causally linked. We manipulated the reproductive success (enlarged, reduced, and control broods) in a nest-box population of migratory pied flycatchers, Ficedula hypoleuca, in Finland...

In this work, we tested canonical and domain based pair natural orbital coupled cluster methods (CCSD(T) and DLPNO-CCSD(T), respectively) for a set of 32 ligand exchange and association/dissociation reaction enthalpies involving ionic complexes of Li, Be, Na, Mg, Ca, Sr, Ba and Pb(ii). Two strategies were investigated: in the former, only valence electrons were included in the correlation treatment, giving rise to the computationally very efficient FC (frozen core) approach; in the latter, all non-ECP electrons were included in the correlation treatment, giving rise to the AE (all electron) approach...

A facile and green mechanosynthesis strategy free of solvent and high reaction temperature was developed to fabricate highly emissive cesium lead halide perovskite (CsPbX3) quantum dots (QDs). Their composition can be adjusted conveniently simply through mechanically milling/grinding stoichiometric combinations of raw reagents, thereby introducing a broad luminescence tunability of the product with adjustable wavelength, linewidth and photoluminescence quantum yield. Desired CsPbX3 QDs "library" can thus be readily constructed in a way like assembling Lego building blocks...

Metabotropic glutamate receptors (mGluRs) are important modulators of excitatory neurotransmission, and have been implicated in addiction to alcohol and anxiety-related behaviors. However, the behavioral consequence and contribution of individual subtypes are not known yet. This study determined the effects of mGluR8 activation on anxiety-like behavior, voluntary ethanol intake and ethanol-induced conditioned reward. To this aim, anxiety and spontaneous behavior were measured in C57BL/6J mice using the elevated plus maze (EPM), open field (OF) and light-dark box (LDB) tests after systemic injection of the selective mGluR8 agonist (S)-3,4-dicarboxyphenylglycine ((S)-3,4-DCPG)...

Current multiplexed diagnostics for Zika, dengue, and chikungunya viruses are situated outside the intersection of affordability, high performance, and suitability for use at the point-of-care in resource-limited settings. Consequently, insufficient diagnostic capabilities are a key limitation facing current Zika outbreak management strategies. Here we demonstrate highly sensitive and specific detection of Zika, chikungunya, and dengue viruses by coupling reverse-transcription loop-mediated isothermal amplification (RT-LAMP) with our recently developed quenching of unincorporated amplification signal reporters (QUASR) technique...

Absorption of dietary sphingomyelin (SM) requires its initial degradation into ceramide, a process catalyzed by the intestinal enzyme alkaline sphingomyelinase (alk-SMase, NPP7, ENPP7). Alk-SMase belongs to the nucleotide pyrophosphatase / phosphodiesterase family, the members of which hydrolyze nucleoside phosphates, phospholipids and other related molecules. NPP7 is the only paralog that can cleave SM, and its activity requires the presence of bile salts, a class of physiological anionic detergents. To elucidate the mechanism of substrate recognition, we determined the crystal structure of human alk-SMase in complex with phosphocholine, a reaction product...

Slow eye movement (SEM) is reported as a reliable indicator of sleep onset period (SOP) in sleep researches, but its characteristics and functions for detecting driving fatigue have not been fully studied. Through visual observations on ten subjects' experimental data, we found that SEMs tend to occur during eye closure events (ECEs). SEMs accompanied with alpha wave's attenuation during simulated driving was observed in our study. We used box plots to analyze the distribution of durations of different ECEs to measure sleepiness level...

The development of smartphone-based biosensors for point-of-care testing (POCT) applications allows realizing "all in one" instruments, with large potential distribution among the general population. With this respect, paper color-based detection performed by reflectance measurement is the most popular, simple, inexpensive and straightforward method. Despite the large number of scientific publications related to these biosensors, they still suffer from a poor detectability and reproducibility related to inhomogeneity of color development, which leads to low assay reproducibility...

The p75 neurotrophin receptor (p75NTR) is a low-affinity receptor that is capable of binding neurotrophins. Two different p75NTR knockout mouse lines are available either with a deletion in Exon III (p75NTR(E)(x)(III)(-/-) ) or in Exon IV (p75NTR(E)(x)(IV)(-/-) ). In p75NTR(E)(x)(III) knockout mice, only the full-length p75NTR is deleted, whereas in p75NTR(E)(x)(IV) knockout mice, the full-length as well as the truncated isoform of the receptor is deleted. Deletion of p75NTR has been shown to affect, among others, the septo-hippocampal cholinergic innervation pattern and neuronal plasticity within the hippocampus...

OBJECTIVES: There are several models of depression. Chronic unpredictable mild stress (CMS) appears to have the greatest validity, although it is often being criticized for low reliability. METHODS: Male Wistar/DV rats were used in this study to assess our modified 2-week model of CMS as a combination of psychosocial, physical and metabolic stressors and to compare the effect of acute administration of venlafaxine (VFX) and diazepam (DZP), either in stress or no stress conditions...

In recent years, the myocardium has been rediscovered under the lenses of immunology, and lymphocytes have been implicated in the pathogenesis of cardiomyopathies with different etiologies. Aging is an important risk factor for heart diseases, and it also has impact on the immune system. Thus, we sought to determine whether immunological activity would influence myocardial structure and function in elderly mice. Morphological, functional, and molecular analyses revealed that the age-related myocardial impairment occurs in parallel with shifts in the composition of tissue-resident leukocytes and with an accumulation of activated CD4(+) Foxp3(-) (forkhead box P3) IFN-γ(+) T cells in the heart-draining lymph nodes...

The presence of a network of areas in the parietal and premotor cortices, which are active both during action execution and observation, suggests that we might understand the actions of other people by activating those motor programs for making similar actions. Although neurophysiological and imaging studies show an involvement of the somatosensory cortex (SI) during action observation and execution, it is unclear whether SI is essential for understanding the somatosensory aspects of observed actions. To address this issue, we used off-line transcranial magnetic continuous theta-burst stimulation (cTBS) just before a weight judgment task...

Jujube (Ziziphus Jujuba Mill.) fruit has been utilized as an adjunct to alleviate medical symptoms including, but not limited to, anorexia, fatigue, anxiety and mild diarrhea for centuries. Despite a growing body of literature revealing jujube fruit's health promoting properties such as anti-cancer, anti-inflammation and anti-oxidant effects (shown with cell-based in vitro platforms), there is a paucity of studies systemically examining its impact on whole organisms or throughout the entire course of life utilizing in vivo model systems...

Regulation of the flowering mechanism is influenced by many environmental factors. Dissecting the regulatory processes upstream of the LFY (LEAFY) gene will help us to understand the molecular mechanisms of floral induction. In total, 53 LFY sequences were identified in 37 species. Among the 53 selected LFY promoters and after eliminating the short sequences, 47 LFY promoters were analyzed. Comparative genome studies for LFY promoters among plants showed that TATA-box existed in all herbaceous plants. The 1345-bp promoter sequence upstream to hickory LFY gene was cloned and analyzed, together with functional studies...

Wheat germ has an important enzymatic activity, being lipases the enzymes which cause the highest impact in the reduction of shelf life. The objective of this study was to evaluate the effects of infrared radiation on wheat germ stabilization in an attempt to extend the shelf life. The effects of treatment time, gap (sample distance to IR emitters) and infrared radiation intensity on wheat germ were analyzed through response surface methodology. Final moisture content, final temperature, color of germ and germ oil quality parameters: free fatty acid content changes and total tocopherol content were the responses evaluated using a Box-Behnken design...
