Long noncoding RNA integrates a DNA-PK-mediated DNA damage response and vascular senescence.

Long noncoding RNAs (lncRNAs) are emerging regulators of biological processes in the vessel wall; however, their role in atherosclerosis remains poorly defined. We used RNA sequencing to profile lncRNAs derived specifically from the aortic intima of mice on a high-cholesterol diet during lesion progression and regression phases. We found that the evolutionarily conserved lncRNA small nucleolar host gene-12 () is highly expressed in the vascular endothelium and decreases during lesion progression.

Impact of a TeamSTEPPS Trauma Nurse Academy at a Level 1 Trauma Center.

Problem: Nurses are crucial members of the team caring for the acutely injured trauma patient. Until recently, nurses and physicians gained an understanding of leadership and supportive roles separately. With the advent of a multidisciplinary team approach to trauma care, formal team training and simulation has transpired.

Thromboelastography in healthy dairy cows.

Thromboelastography is a whole blood-based coagulation assay that can be used to investigate hypocoagulability and hypercoagulability, as seen with thromboembolic diseases and disseminated intravascular coagulation. Numerous coagulopathies due to different causes are reported in cows. The objective was to establish reference intervals for thromboelastography using the TEG 5000 (Haemonetics GmbH, Munich, Germany) with citrated whole blood samples and kaolin activation in dairy cows and to investigate possible thromboelastographic changes between cows in different lactation periods.

Discovery and optimization of a series of benzothiazole phosphoinositide 3-kinase (PI3K)/mammalian target of rapamycin (mTOR) dual inhibitors.

Phosphoinositide 3-kinase α (PI3Kα) is a lipid kinase that plays a key regulatory role in several cellular processes. The mutation or amplification of this kinase in humans has been implicated in the growth of multiple tumor types. Consequently, PI3Kα has become a target of intense research for drug discovery.

Testing a social-cognitive model of moral behavior: the interactive influence of situations and moral identity centrality.

This article proposes and tests a social-cognitive framework for examining the joint influence of situational factors and the centrality of moral identity on moral intentions and behaviors. The authors hypothesized that if a situational factor increases the current accessibility of moral identity within the working self-concept, then it strengthens the motivation to act morally. In contrast, if a situational factor decreases the current accessibility of moral identity, then it weakens the motivation to act morally.

Overcoming beneficiary race as an impediment to charitable donations: social dominance orientation, the experience of moral elevation, and donation behavior.

Three studies examined the relationship between social dominance orientation (SDO), the experience of moral elevation, and Whites' donations to charitable organizations. Study 1 used video clips depicting acts of moral excellence to elicit a state of moral elevation (a distinctive feeling of warmth and expansion, which is accompanied by admiration, affection, and even love for people whose exemplary moral behavior is being observed). Results show that moral elevation increased participants' willingness to donate to a Black-oriented charity and attenuated the negative effect of the group-based dominance (GBD) component of SDO on donation behavior.

Youths' understandings of cigarette advertisements.

This study addresses two questions: (1) when youths are exposed to advertisements for cigarettes, do they primarily see advertisements for brands or products, and (2) is there a relationship between youths' understandings of cigarette advertisements and their susceptibility to smoking? A sample of 271 participants ranging in age from 7 to 12 viewed a series of print advertisements that included cigarette and non-tobacco-related ads. While viewing each ad, participants were asked to indicate what they thought the advertisement was trying to sell. Responses were coded into one of three categories reflecting important differences in participants' comprehension of each advertisement - no understanding, product category understanding, or brand understanding.

Genetic background controls tumor development in PTEN-deficient mice.

PTEN is one of the most frequently mutated tumor suppressor genes in human cancers. Germ line mutations of PTEN have been detected in three rare autosomal-dominant disorders. However, identical mutations in the PTEN gene may lead to different symptoms that have traditionally been described as different disorders, such as Cowden disease, Lhermitte-Duclos disease, and Bannayan-Zonana syndromes.

PTEN deletion leads to up-regulation of a secreted growth factor pleiotrophin.

Tumor suppressor gene PTEN is highly mutated in a wide variety of human tumors. To identify unknown targets or signal transduction pathways that are regulated by PTEN, microarray analysis was performed to compare the gene expression profiles of Pten null mouse embryonic fibroblasts (MEFs) cell lines and their isogenic counterparts. Expression of a heparin binding growth factor, pleiotrophin (Ptn), was found to be up-regulated in Pten-/- MEFs as well as Pten null mammary tumors.

Young children's understandings of cigarette smoking.

Aims: We explore young children's attitudes toward, beliefs about, and life-style associations with cigarette smoking using direct and indirect measures.

Design, Setting And Participants: Second (n = 100) and fifth grade (n = 141) elementary school students (i.e.
