We present simulations using finite-temperature density-functional-theory molecular dynamics to calculate the dynamic electrical conductivity in warm dense aluminum. The comparison between exchange-correlation functionals in the Perdew-Burke-Enzerhof and Heyd-Scuseria-Enzerhof (HSE) approximation indicates evident differences in the density of states and the dc conductivity. The HSE calculations show excellent agreement with experimental Linac Coherent Light Source x-ray plasmon scattering spectra revealing plasmon damping below the widely used random phase approximation...

When cells are exposed to heat shock and various other stresses, heat shock factor 1 (HSF1) is activated and the heat shock response (HSR) is elicited. To better understand the molecular regulation of the HSR, we used 2D-PAGE based proteome analysis to screen for heat shock-induced posttranslationally modified cellular proteins. Our analysis revealed that two protein spots typically present on 2D-PAGE gels and containing heterogeneous nuclear ribonucleoprotein K (hnRNP K) with trioxidized Cys132 disappeared after the heat shock treatment and reappeared during recovery, but the total amount of hnRNP K protein remained unchanged...

The leaves of Petasites japonicus are used for their anti-allergic properties in traditional Korean, Japanese, and Chinese medicine. This study aimed to identify bioactive compounds isolated from P. japonicus leaves. All compounds were assessed for their ability of transcriptional activation, induction of phase 2 enzymes and heat shock proteins (HSPs), as well as protection against the UVB-induced apoptotic cell death. Bioactive compounds were isolated from P. japonicus leaves. All compounds were evaluated for their protective effect using human dermal fibroblasts (HDF) and human epidermal keratinocyte cells (HEKC) treated with UVB radiation...

A particularly challenging aspect of forensic casework is the accurate interpretation of samples that contain DNA from more than one contributor, since DNA analysis of specific identification markers often results in ambiguous mixed profiles. Physically separating the various haploid components of a diploid or polyploid DNA sample or of a specimen containing DNA from multiple individuals can resolve this problem. We adapted and combined previously developed methods of haplotype-specific extraction (HSE) to separate and analyze mitochondrial DNA (mtDNA) in samples containing DNA from two individuals...

Neutron diffraction of tri(3,5-tert-butylphenyl)methane at 20 K reveals an intermolecular C-H···H-C distance of only 1.566(5) Å, which is the shortest reported to date. The compound crystallizes as a C3-symmetric dimer in an unusual head-to-head fashion. Quantum chemical computations of the solid state at the HSE-3c level of theory reproduce the structure and the close contact well (1.555 Å at 0 K) and emphasize the significance of packing effects; the gas-phase dimer structure at the same level shows a 1...

We investigated the effects of co-enzyme Q10 (Q10) and acetyl salicylic acid (ASA) on expression of Hsp70 in the protection of primary chicken myocardial cells during heat stress. Western blot analysis showed that Q10 and ASA accelerated the induction of Hsp70 when chicken myocardial cells were exposed to hyperthermia. In the absence of heat stress, however, neither Q10 nor ASA are able to upregulate Hsp70 expression. Analysis of enzymes that respond to cellular damage and pathological examination revealed that ectopic expression of ASA and Q10 alleviate cellular damage during heat stress...

The heat stress transcription factors (Hsfs) play a prominent role in thermotolerance and eliciting the heat stress response in plants. Identification and expression analysis of Hsfs gene family members in chickpea would provide valuable information on heat stress responsive Hsfs. A genome-wide analysis of Hsfs gene family resulted in the identification of 22 Hsf genes in chickpea in both desi and kabuli genome. Phylogenetic analysis distinctly separated 12 A, 9 B, and 1 C class Hsfs, respectively. An analysis of cis-regulatory elements in the upstream region of the genes identified many stress responsive elements such as heat stress elements (HSE), abscisic acid responsive element (ABRE) etc...

BACKGROUND: Herpes simplex encephalitis (HSE) after primary HSV-1 infection can occur in children due to inborn errors of cell-intrinsic immunity in the central nervous system (CNS). Paradoxically, symptomatic mucocutaneous HSV-1 recurrences are rare survivors of childhood HSE. T-cell acquired immunity is thought to be involved in control of recurrent mucocutaneous HSV infection. We thus tested HSV-1-specific immunity in HSE survivors. METHODS: We obtained serum and peripheral blood mononuclear cells (PBMC) a median of 13...

A 55-year-old man was admitted to our hospital for investigation of high fever, decreased consciousness and bilateral visual impairment. His cerebrospinal fluid analysis revealed pleocytosis of mononuclear cells and an increased protein concentration. FLAIR images revealed multiple high-intensity lesions in the frontal lobe, part of which was enhanced with gadolinium. Despite initiating treatment with acyclovir and corticosteroids, his consciousness and visual acuity deteriorated. Immunopathological examination of brain biopsies showed numerous herpes simplex virus type 2-positive neurons and macrophages, leading to a diagnosis of herpes simplex encephalitis (HSE)...

Plant miR164 family is highly conserved and miR164 members regulate conserved targets belonging to NAC transcription factors. Our previous studies have revealed that peu-miR164a-e and its target gene POPTR_0007s08420 participate in abiotic stress response in Populus euphratica according to deep sequencing and degradome sequencing. In this study, miR164 family comprises six members that generate two mature products (miR164a-e and miR164f) and target seven NAC genes in P. euphratica. Co-expression in Nicotiana benthamiana and 5' RACE confirmed that peu-miR164 directs PeNAC070, PeNAC012 and PeNAC028 mRNAs cleavage...

Glioblastoma (GBM) is associated with poor prognosis due to its resistance to surgery, irradiation, and conventional chemotherapy. Thus, efficient therapeutic approaches for the treatment of GBM are urgently needed. HSP70 is an antiapoptotic protein that participates in the inhibition of both mitochondrial and membrane receptor apoptosis pathways and is highly expressed in glioma tissues. Here, we investigated a derivative of apoptin; specifically, a chicken anemia viral protein with selective toxicity toward cancer cells that can inhibit hyperactive molecules, including HSP70...

Defects in genes of the Toll-like receptor 3 (TLR3) pathway are associated with susceptibility to herpes simplex virus type 1 encephalitis (HSE). We analyzed a cohort of 11 adult Italian patients in whom viral encephalitis developed. We detected 2 rare missense mutations in TLR3: 1 in a patient with HSE (p.Leu297Val) and 1 in a patient with varicella-zoster virus encephalitis (p.Leu199Phe). Both mutations are extremely rare in human populations and have pathogenicity scores highly suggestive of a functional effect...

INTRODUCTION: [(11)C]Flumazenil is a well-known PET tracer for GABAA receptors and is mainly used as an imaging biomarker for neuronal loss. Recently, GABAA receptors on immune cells have been investigated as target for modulation of inflammation. Since neuronal loss is often accompanied by neuroinflammation, PET imaging with [(11)C]flumazenil is potentially affected by infiltrating immune cells. This may also compromise the validity of using the pons as reference tissue in quantitative pharmacokinetic analysis...

The Health and Safety Executive (HSE) in Great Britain (GB), in association with its stakeholders, developed the Control of Substances Hazardous to Health (COSHH)-Essentials (C-E) control banding tool in 1998. The objective was to provide a simple tool for employers, particularly small and medium-sized enterprises (SMEs), to help select and apply appropriate measures for the adequate control of exposure to hazardous substances. The tool used hazard classification information (R-phrases) to assign substances to one of five health hazard groups, each with its respective 'target airborne concentration range'...

In view of their high nonlinear optical coefficients and good phase-matching properties, CdSiP2 (CSP) crystals are considered as one of the most promising materials in the field of nonlinear optical applications. However, the slight absorption losses around 1.34 μm and 1.78 μm under e-polarized light have been affecting its performance. In this study, first-principles calculations were performed to identify the effects of various charge defects on the absorption properties. Different intrinsic defects in the CSP crystal were calculated using the HSE method and compared according to the specific chemical environments in the experiments...

The effects of color perception are utilized in visual displays for the purpose of safety in the workplace and in daily life. These effects, generally known as color functionality, are divided into four classifications: visibility, legibility, conspicuity and discriminability. This article focuses on the relationship between the color functionality of color schemes used in visual displays for occupational and environmental safety and color vision deficiency (particularly congenital red-green color deficiency), a critical issue in ophthalmology, and examines the effects of color functionality on the perception of the color red in individuals with protan defects...
