BACKGROUND/AIMS: Pancreatic carcinoma (PC) is the one of the most common and malignant cancers worldwide. LncRNA taurine upregulated gene 1 (TUG1) was initially identified as a transcript upregulated by taurine, and the abnormal expression of TUG1 has been reported in many cancers. However, the biological role and molecular mechanism of TUG1 in PC still needs further investigation. METHODS: Quantitative real-time PCR (qRT-PCR) was performed to measure the expression of TUG1 in PC cell lines and tissues...

Several β2-microglobulin (B2M) -bound protein complexes undertake key roles in various immune system pathways, including the neonatal Fc receptor (FcRn), cluster of differentiation 1 (CD1) protein, non-classical major histocompatibility complex (MHC), and well-known MHC class I molecules. Therefore, the duplication of B2M may lead to an increase in the biological competence of organisms to the environment. Based on the pig genome assembly SSC10.2, a segmental duplication of ~45.5 kb, encoding the entire B2M protein, was identified in pig chromosome 1...

REVIEW
Jack C Watson, William C Way, Robert C Hilliard
The field of sport psychology is dynamic and growing. To continue building credibility with the public and allied professionals, effective and ethical practice is crucial. Advances in technology have allowed sport psychology professionals to consult with athletes from a distance, but practitioners must be mindful of their competency to use technology, confidentiality concerns, and the suitability of technology for their clients. Movement toward defining competency and clarifying issues of title usage are additional areas in which the field is gaining momentum...

REVIEW
April S Masarik, Rand D Conger
In the present report, we provide an illustrative review of the Family Stress Model (FSM) framework [1] to understand how family stress influences children across development in physical, social-emotional, and cognitive domains. We note that the FSM as a theory has evolved through inspection of: (a) new explanatory pathways (mediators); (b) factors that moderate FSM pathways; and (c) joint tests of competing models. Also important, most researchers cited in this review used longitudinal designs to test the proposed causal ordering of FSM pathways, which replicated among a diverse set of families varied in structure, ethnic background, and geographic location...

REVIEW
Harold D Grotevant, Albert Yh Lo
Challenges in adoptive parenting continue to emerge as adoption policies and practices evolve. We review three areas of research in adoptive parenting that reflect contemporary shifts in adoption. First, we highlight recent findings concerning openness in adoption contact arrangements, or contact between a child's families of birth and rearing. Second, we examine research regarding racial and cultural socialization in transracial and international adoptions. Finally, we review investigations of parenting experiences of lesbian and gay adoptive parents...

OBJECTIVES: Competency-based education places increasing emphasis on formative feedback to learners as part of the assessment process. We wished to determine if gender bias was present in the feedback shared with post-graduate medical trainees (residents) in a two-year family medicine residency program at a Canadian university. METHODS: We performed secondary data analyses of documented feedback (FieldNotes) extracted from the Competency-Based Achievement System database...

Arabidopsis thaliana exhibits a developmentally regulated disease-resistance response known as Age-Related Resistance (ARR), a process that requires intercellular accumulation of salicylic acid (SA), which is thought to act as an antimicrobial agent. ARR is characterized by enhanced resistance to some pathogens at the late adult-vegetative and reproductive stages. While the transition to flowering does not cause the onset of ARR, both processes involve the MADS-domain transcription factor SHORT VEGETATIVE PHASE (SVP)...

The inadequate supply of health workers and demand-side barriers due to clinical practice that heeds too little attention to cultural context are serious obstacles to achieving universal health coverage and the fulfillment of the human rights to health, especially for the poor and vulnerable living in remote rural areas. A number of strategies have been deployed to increase both the supply of healthcare workers and the demand for healthcare services. However, more can be done to improve service delivery as well as mitigate the geographic inequalities that exist in this field...

EDITORIAL
Russell Mannion, Mark Exworthy
Recent years have witnessed a parallel and seemingly contradictory trend towards both the standardization and the customization of healthcare and medical treatment. Here, we explore what is meant by 'standardization' and 'customization' in healthcare settings and explore the implications of these changes for healthcare delivery. We frame the paradox of these divergent and opposing factors in terms of institutional logics - the socially constructed rules, practices and beliefs which perpetuate institutional behaviour...

We report on an experimental single-photon absorption study on gas-phase protonated collagen peptides employing a combination of mass spectrometry and synchrotron radiation. Partial ion yields for the main photoabsorption products vary steadily with photon energy over the range from 14 to 545 eV. At low energy, non-dissociative photoionisation competes with neutral molecule loss from the precursor ion, whereas fragmentation of the peptide backbone dominates at soft X-ray energies. Neutral molecule losses from the ionised peptide are found to have low energy barriers and most likely involve amino-acid residue side-chains with radical character, in particular aspartic acid...

Microorganisms are the most abundant, diverse and functionally important organisms on Earth. Over the past decade, microbial ecologists have produced the largest ever community datasets. However, these data are rarely used to uncover law-like patterns of commonness and rarity, test theories of biodiversity, or explore unifying explanations for the structure of microbial communities. Using a global scale compilation of >20,000 samples from environmental, engineered and host-related ecosystems, we test the power of competing theories to predict distributions of microbial abundance and diversity-abundance scaling laws...

Animal social organization varies from complex societies where reproduction is dominated by a single individual (eusociality) to those where reproduction is more evenly distributed among group members (communal breeding). Yet, how simple groups transition evolutionarily to more complex societies remains unclear. Competing hypotheses suggest that eusociality and communal breeding are alternative evolutionary endpoints, or that communal breeding is an intermediate stage in the transition towards eusociality. We tested these alternative hypotheses in sponge-dwelling shrimps, Synalpheus spp...

Competition can profoundly affect biodiversity patterns by determining whether similar species are likely to coexist. When species compete directly for space, competitive ability differences should theoretically promote trait and phylogenetic clustering, provided that niche differences are otherwise minimal. Yet many sessile communities exhibit high biodiversity despite minimal reliance on niche differentiation. A potential explanation is that intransitive competition ('rock-paper-scissors' competition) not only promotes species richness but also fosters coexistence among highly dissimilar species with different competitive strategies...

The increasing availability of genotype-phenotype maps for different combinations of mutations has empowered evolutionary biologists with the tools to interrogate the predictability of adaptive evolution, especially in the context of the evolution of antimicrobial resistance. Large microbial populations are known to generate competing beneficial mutations, but determining how these mutations contribute to the adaptive trajectories that are most likely to be followed remains a challenge. Despite a recognition that there may also be competition between successive alleles on the same trajectory, prior studies have not fully considered how this impacts adaptation rates along, or likelihood of following, individual trajectories...

Jan Martinus Anne de Vries, Fiona Timmins
This article is the first in a two-part series discussing declining standards of care. Many healthcare organisations, particularly hospitals, are under increased pressure to maintain standards of care while experiencing funding and staff shortages, and increasing patient numbers and demand for services. One of the main risks associated with these competing demands is a gradual decline in care standards, described as 'care erosion' in this article. Understanding the psychosocial mechanisms that can lead to care erosion is important in preventing its occurrence...

Healthcare is a complex area with significant potential for service improvement despite the effects of increasing economic and social pressures on the quality and safety of patient care. As the largest group of healthcare professionals in direct contact with patients, nurses are well positioned to contribute to improvements in healthcare services and to the development of new policies. To influence healthcare improvements and policies effectively, nurses require leadership skills. Historically, it was thought that only nurses in management roles required leadership skills; however, the ability to influence change is a requirement at all levels of clinical practice...

The coordination of tBuPONOP (tBuPONOP = 2,6-bis(ditertbutylphosphinito)pyridine) to different ruthenium starting materials, to generate (tBuPONOP)RuCl2, was investigated. The 16-electron species (tBuPONOP)Ru(H)Cl was produced from the reaction of triethylsilane with (tBuPONOP)RuCl2. Reactions of (tBuPONOP)RuCl2 with both phenylsilane or diphenylsilane afforded the 16-electron hydrido-silyl species (tBuPONOP)Ru(H)(PhSiCl2) and (tBuPONOP)Ru(H)(Ph2SiCl), respectively. Reactions of all three of these complexes with silver triflate afforded the simple salt metathesis products of (tBuPONOP)Ru(H)(OTf), (tBuPONOP)Ru(H)(PhSiCl(OTf)), and (tBuPONOP)Ru(H)(Ph2Si(OTf))...

The expression of emotion in faces serves numerous meaningful functions, such as conveying messages of danger or approach, facilitating communication, and promoting the formation of social bonds and relationships. The study of facial expressions of emotion has become integral to research in social psychology and social neuroscience, particularly with respect to the neuropeptide oxytocin. This chapter examines how oxytocin influences the processing of emotion in faces by reviewing intranasal administration studies of automatic processing, selective attention, and emotion recognition...
