A multifaceted intervention at all six obstetric units in the Stockholm Health Region was performed in 2008-2011 in order to increase safety for the newborn infants. Case-controlled criterion-based reviews of care processes during labor and delivery have been used to assess factors associated with suboptimal care during labor and delivery. Categories of increased risk of adverse outcome during labor and delivery were defined. Cases with low Apgar scores and healthy controls were scrutinized and compared to data from a study with an identical design performed before the intervention...

Fifty percent of adolescents have tried an illicit drug and 70% have tried alcohol by the end of high school, with even higher rates among multiracial youth. Ethnic identity is a protective factor against substance use for minority groups. However, little is known about the mechanisms that facilitate its protective effects, and even less is known about this relationship for multiracial youth. The purpose of the present study was to examine the protective effect of ethnic identity on substance use and to determine whether this relationship operated indirectly through self-esteem, a strong predictor of substance use for among adolescent populations...

Autophagy is a highly conserved degradation pathway among eukaryote cells, which can recycle damaged or unwanted cell materials upon encountering stress conditions. As a key component of the Class III PI3K kinase complex, ATG6/Beclin-1 is essential for autophagosome formation. In this study, we isolated a putative HvATG6 gene in barley genome. The protein encoded by HvATG6 shares high sequence identity to ATG6 orthologs in rice and wheat, and has a typical autophagy-specific domain containing segments of repeated β-sheet-α-helix...

On mild acid degradation of the lipopolysaccharide of Enterobacter cloacae C5529, the O-polysaccharide chain was cleaved at the linkages of 5,7-diacetamido-3,5,7,9-tetradeoxy-l-glycero-l-manno-non-2-ulosonic acid (di-N-acetylpseudaminic acid, Psep5Ac7Ac). The resultant oligosaccharide and an alkali-treated lipopolysaccharide were studied by sugar analysis along with (1)H and (13)C NMR spectroscopy, and the following structure of the tetrasaccharide repeating unit of the O-polysaccharide was established: →4)-β-Psep5Ac7Ac-(2 → 3)-β-d-Galp-(1 → 6)-β-d-Galf-(1 → 3)-α-d-Galp-(1→ It differs from a structurally related O-polysaccharide of E...

Redox-sensitive potassium channels consisting of the voltage-gated K(+) (KV) channel pore subunit KV1.5 regulate resting membrane potential and thereby contractility of vascular smooth muscle cells. Members of the KV1 family associate with cytosolic auxiliary β subunits, which are members of the aldo-keto reductase (AKR) superfamily (AKR6A subfamily). The Kvβ subunits have been proposed to regulate Kv1 gating via pyridine nucleotide cofactor binding. However, the molecular identity of KVβ subunits that associate with native KV1...

We provide evidence for location and function of a small conductance, Ca(2+)-activated K(+) (SKCa) channel isoform 3 (SK3) in mitochondria (m) of guinea pig, rat and human ventricular myocytes. SKCa agonists protected isolated hearts and mitochondria against ischemia/reperfusion (IR) injury; SKCa antagonists worsened IR injury. Intravenous infusion of a SKCa channel agonist/antagonist, respectively, in intact rats was effective in reducing/enhancing regional infarct size induced by coronary artery occlusion...

The HID-Ion AmpliSeq™ Identity Panel amplifies 90 autosomal SNPs and 34 Y- SNPs with massively parallel sequencing (MPS) using the Ion Torrent PGM™ platform. In the present study, 105 Basques were analyzed to assess this panel. All loci were in Hardy-Weinberg equilibrium and no association between them was detected. Forensic parameters were calculated as 5.74×10(-36) for combined match probability and 99.99998% for combined power of exclusion. In conclusion, the HID Identity panel and the use of this new MPS technology are very promising tools for paternity testing and human identification in routine casework in the forensic field...

This article proposes a reflection on the exclusion of particularly vulnerable human beings as a condition for the success of economistic culture and social organization. This fragility can depend on the body side as well as the social aspect: the effects of discrimination are identical. To react to a situation of injustice less and less tolerable, the biolaw touches -as in general the right, if it has a meaning and a specific function, and is not reduced to mere legitimization of the balance of forces or interest of the individuals or the groups better organized and represented- defend the fragility of all violence in the name of equality among human beings which depend on the universal condition of vulnerability, held in its positive aspects by philosophers such as MacIntyre and Nussbaum and many literary geniuses of all times...

Although recent work suggests that opposite-sex facial attractiveness is less salient in memory when individuals are in a committed romantic relationship, romantic relationship quality can vary over time. In light of this, we tested whether activating concerns about romantic relationship quality strengthens memory for attractive faces. Partnered women were exposed briefly to faces manipulated in shape cues to attractiveness before either being asked to think about a moment of emotional closeness or distance in their current relationship...

The human neurotensin 1 receptor (hNTS1) is a G protein-coupled receptor involved in many physiological functions, including analgesia, hypothermia, and hypotension. To gain a better understanding of which signaling pathways or combination of pathways are linked to NTS1 activation and function, we investigated the ability of activated hNTS1, which was stably expressed by CHO-K1 cells, to directly engage G proteins, activate second messenger cascades and recruit β-arrestins. Using BRET-based biosensors, we found that neurotensin (NT), NT(8-13) and neuromedin N (NN) activated the Gαq-, Gαi1-, GαoA-, and Gα13-protein signaling pathways as well as the recruitment of β-arrestins 1 and 2...

In biology, the term "clone" is most widely used to designate genetically identical cells or organisms that are asexually descended from a common progenitor. The concept of clonality in hematology-oncology has received much attention in recent years, as the advent of next-generation sequencing platforms has provided new tools for detection of clonal populations in patients, and experiments on primary cells have provided fascinating new insights into the clonal architecture of human malignancies. The term "clone" is used more loosely by the general public to mean any close or identical copy...

Languages exhibit sociolinguistic variation, such that adult native speakers condition the usage of linguistic variants on social context, gender, and ethnicity, among other cues. While the existence of this kind of socially conditioned variation is well-established, less is known about how it is acquired. Studies of naturalistic language use by children provide various examples where children's production of sociolinguistic variants appears to be conditioned on similar factors to adults' production, but it is difficult to determine whether this reflects knowledge of sociolinguistic conditioning or systematic differences in the input to children from different social groups...

The cystic fibrosis transmembrane conductance regulator (CFTR) is an ATP-binding cassette (ABC) transporter that uniquely functions as an ion channel. Here, we present a 3.9 Å structure of dephosphorylated human CFTR without nucleotides, determined by electron cryomicroscopy (cryo-EM). Close resemblance of this human CFTR structure to zebrafish CFTR under identical conditions reinforces its relevance for understanding CFTR function. The human CFTR structure reveals a previously unresolved helix belonging to the R domain docked inside the intracellular vestibule, precluding channel opening...

Objectives: Determination of the primary site of origin for mucinous neoplasms identified in the peritoneal and/or pelvic cavities may be challenging, with major differential diagnoses including appendiceal mucinous neoplasm (AMN) and ovarian mucinous neoplasm (OMN). Special AT-rich sequence binding protein 2 (SATB2) has been shown to be highly selectively expressed in the lower gastrointestinal tract, including the appendix. Methods: We investigated the utility of a dual stain (DS) with SATB2 or caudal type homeobox 2 (CDX2) and cytokeratin 20 (CK20) or villin in distinguishing AMNs from OMNs...

Introduction: Lesbian, gay, and bisexual (LGB) adults have higher rates of smoking than heterosexual adults. LGB individuals face unique stressors, including challenges associated with having a LGB identity. The extent to which these unique stressors are related to dependence motives in LGB adult smokers, however, has not been previously explored. The current study was conducted to redress these gaps. Methods: Participants (N=52; Mage=42.8; 55.8% Black/African American) were recruited from the local community...

During human pregnancy, fetal extravillous trophoblasts (EVT) play a key role in the regulation of maternal T cell and NK cell responses. EVT display a unique combination of Human Leukocyte Antigens (HLA); EVT do not express HLA-A and HLA-B, but do express HLA-C, HLA-E and HLA-G. The mechanisms establishing this unique HLA expression pattern have not been fully elucidated. The MHC class I and class II transcriptional activators NLRC5 and CIITA are expressed neither by EVT nor by the EVT model cell line JEG3, which has an MHC expression pattern identical to that of EVT...

There is a dearth of information on the quality of health care for Asian American children and particularly Asian children with special health care needs (CSHCN). The goal of this article was to determine whether there were disparities in quality of health care for Asian CSHCN, whose experiences have not been studied. Data were derived from the 2009-2010 National Survey of Children with Special Health Care Needs (ns = 355 non-Hispanic Asian children and 4,343 non-Hispanic white CSHCN). Bivariate and multivariate logistic regression analyses were conducted to examine the relationship between racial identity (that is, non-Hispanic white and non-Hispanic Asian) and quality of health care...

Marek's disease ( ) is a lymphoproliferative disease caused by an Alphaherpesvirus, genus Mardivirus , serotype 1 ( Gallid Herpesvirus 2 , GaHV-2) that includes all known pathogenic strains. In addition to Marek's disease virus ( ) serotype 1, the genus includes 2 distinct nonpathogenic serotypes: serotype 2 (GaHV-3) and serotype 3 ( Meleagridis Herpesvirus 1 , MeHV-1) which are used in commercially available vaccines against MD. As a result of vaccination, clinical signs are not commonly observed, and new cases are usually associated with emerging variant strains against which the vaccines are less effective...
