Romantic and sexual relationships of young adults born very preterm: An individual participant data meta-analysis.

Aim: To compare romantic and sexual relationships between adults born very preterm (VP; <32 weeks of gestation) or with very low birth weight (VLBW; <1500 g) and at term, and to evaluate potential biological and environmental explanatory factors among VP/VLBW participants.

Methods: This individual participant data (IPD) meta-analysis included longitudinal studies assessing romantic and sexual relationships in adults (mean sample age ≥ 18 years) born VP/VLBW compared with term-born controls. Following PRISMA-IPD guidelines, 11 of the 13 identified cohorts provided IPD from 1606 VP/VLBW adults and 1659 term-born controls.

Protein inclusion into ice can dissociate subunits.

An antifreeze protein's inclusion into ice can be used to purify it from other proteins and solutes. Domains that are covalently attached to the antifreeze protein are also drawn into the ice such that the ice-binding portion of the fusion protein can be used as an affinity tag. Here we have explored the use of ice-affinity tags on multi-subunit proteins.

Parents' life satisfaction prior to and following preterm birth.

The current study tested whether the reported lower wellbeing of parents after preterm birth, relative to term birth, is a continuation of a pre-existing difference before pregnancy. Parents from Germany (the German Socio-Economic Panel Study, N = 10,649) and the United Kingdom (British Household Panel Study and Understanding Society, N = 11,012) reported their new-born's birthweight and gestational age, subsequently categorised as very preterm or very low birthweight (VP/VLBW, < 32 weeks or < 1500 g), moderately/late preterm or low birthweight (MLP/LBW, ≥ 32 weeks and < 37 weeks/≥ 1500 g and < 2500 g), or term-born (≥ 37 weeks and ≥ 2500 g). Mixed models were used to analyse life satisfaction, an aspect of wellbeing, at four assessments-two years and six months before birth and six months and two years afterwards.

A peptide-binding domain shared with an Antarctic bacterium facilitates human cell binding and intestinal colonization.

the causative agent of the disease cholera, is responsible for multiple pandemics. binds to and colonizes the gastrointestinal tract within the human host, as well as various surfaces in the marine environment (e.g.

Association of Birth Weight Centiles and Gestational Age With Cognitive Performance at Age 5 Years.

Importance: Birth weight percentiles (BWPs) are often dichotomized at the 10th percentile and show statistically significant association with later cognitive performance, for both preterm and term-born children. However, research testing nonlinear associations between BWPs and cognitive performance is scarce.

Objective: To investigate culturally invariant, nonlinear associations of BWPs and gestational age with later cognitive performance.

Lower hypothalamus subunit volumes link with impaired long-term body weight gain after preterm birth.

Introduction: Preterm birth is associated with an increased risk for impaired body weight gain. While it is known that in prematurity several somatic and environmental factors (e.g.

Social Functioning in Adults Born Very Preterm: Individual Participant Meta-analysis.

Context: There is a lack of research on individual perceptions of social experiences and social relationships among very preterm (VP) adults compared with term-born peers.

Objective: To investigate self-perceived social functioning in adults born VP (<32 weeks' gestation) and/or with very low birth weight (VLBW) (<1500g) compared with term-born adults (≥37 weeks' gestation) using an individual participant data (IPD) meta-analysis.

Data Sources: Two international consortia: Research on European Children and Adults born Preterm and Adults Born Preterm International Collaboration.

Association of Very Preterm Birth or Very Low Birth Weight With Intelligence in Adulthood: An Individual Participant Data Meta-analysis.

Importance: Birth before 32 weeks' gestation (very preterm [VPT]) and birth weight below 1500 g (very low birth weight [VLBW]) have been associated with lower cognitive performance in childhood. However, there are few investigations of the association of neonatal morbidities and maternal educational levels with the adult cognitive performance of individuals born VPT or VLBW (VPT/VLBW).

Objective: To assess differences in adult IQ between VPT/VLBW and term-born individuals and to examine the association of adult IQ with cohort factors, neonatal morbidities, and maternal educational level among VPT/VLBW participants.

Structural Basis of Ligand Selectivity by a Bacterial Adhesin Lectin Involved in Multispecies Biofilm Formation.

Carbohydrate recognition by lectins governs critical host-microbe interactions. PA14 ( PA14 domain) lectin is a domain of a 1.5-MDa adhesin responsible for a symbiotic bacterium-diatom interaction in Antarctica.

Ice recrystallization inhibition activity varies with ice-binding protein type and does not correlate with thermal hysteresis.

Ice-binding proteins (IBPs) inhibit the growth of ice through surface adsorption. In some freeze-resistant fishes and insects, circulating IBPs serve as antifreeze proteins to stop ice growth by lowering the freezing point. Plants are less able to avoid freezing and some use IBPs to minimize the damage caused in the frozen state by ice recrystallization, which is the growth of large ice grains at the expense of small ones.

Medical pluralism, Pentecostal healing and contests over healing power in Papua New Guinea.

This paper is based on long-term ethnographic fieldwork among the Lelet of New Ireland Province, Papua New Guinea. It draws on qualitative interviews with Pentecostal Christians intended to examine their understanding of Christianity and how this relates to their cultural practices - in this case, how their Pentecostalism affects their therapeutic beliefs and practices. The frequent observation that therapeutic repertoires are becoming less discrete is substantiated by the Lelet case, for in their search for therapy, the Lelet often cross the borders of different repertoires, seeing no contradiction, for example, between combining a vernacular therapy with biomedicine.

Crystal structure of an insect antifreeze protein reveals ordered waters on the ice-binding surface.

Antifreeze proteins (AFPs) are characterized by their ability to adsorb to the surface of ice crystals and prevent any further crystal growth. AFPs have independently evolved for this purpose in a variety of organisms that encounter the threat of freezing, including many species of polar fish, insects, plants and microorganisms. Despite their diverse origins and structures, it has been suggested that all AFPs can organize ice-like water patterns on one side of the protein (the ice-binding site) that helps bind the AFP to ice.

Marital sexual violence and conjugality in highlands Papua New Guinea.

Many male coffee farmers in the highlands of Papua New Guinea believe they have a right to sex with their spouse without regard to her wishes. Drawing on quantitative and qualitative data, I argue that such sexual violence is best framed within local understandings of what marriage involves - an implicit contract which conveys rights and responsibilities to each partner in a marriage. Changes brought by modernity are transforming traditional understandings of conjugality, causing some discrepancies in partners' understanding of what they have agreed to.

Small for gestational age-cognitive performance from infancy to adulthood: an observational study.

Objective: To determine whether cognitive performance from infancy to adulthood is affected by being born small for gestational age (SGA), and if this depends on the SGA reference used. Furthermore, to determine SGA's effect while considering the effects of very preterm/very low birthweight (VP/VLBW), socio-economic status (SES) and parent-infant relationship.

Design, Setting And Population: A total of 414 participants (197 term-born, 217 VP/VLBW) of the Bavarian Longitudinal Study.

Carrot 'antifreeze' protein has an irregular ice-binding site that confers weak freezing point depression but strong inhibition of ice recrystallization.

Ice-binding proteins (IBPs) are found in many biological kingdoms where they protect organisms from freezing damage as antifreeze agents or inhibitors of ice recrystallization. Here, the crystal structure of recombinant IBP from carrot (Daucus carota) has been solved to a resolution of 2.3 Å.

The Role of Executive and General Cognitive Functioning in the Attention Problems of Very and Extremely Preterm Adults.

Objective: To determine whether the attention problems in adults born very preterm/very low birth weight (VP/VLBW; <32 weeks' gestation/<1500 g) or extremely preterm (EP; <26 weeks' gestation) are associated with specific executive or general cognitive deficits.

Method: Cohorts of VP/VLBW (the Bavarian Longitudinal Study [BLS]) and EP (the EPICure Study) participants were followed from birth to early adulthood, each also following a respective control group. Adult attention deficit hyperactivity disorder (ADHD) symptoms were assessed via self-report in both cohorts and additionally by parent report in the BLS.

Synergy between Antifreeze Proteins Is Driven by Complementary Ice-Binding.

In some cold-adapted organisms, over a dozen isoforms of antifreeze (glyco)proteins or AF(G)Ps are present. Although these isoforms are structurally similar, their ability to inhibit ice growth varies significantly, and, in some fish, passive isoforms can be much more abundant than the active ones. Laboratory experiments demonstrated more than a decade ago that mixtures of AFP isoforms can exhibit synergistic enhancement of each other's activity.

'Full price, full body': norms, brideprice and intimate partner violence in highlands Papua New Guinea.

This paper draws on qualitative research in Jiwaka Province, in the highlands of Papua New Guinea (PNG), to examine the changing nature of marriage in that context. In particular, it examines how changes in the practice of brideprice have been associated with an increase in intimate partner violence. Violence, a relational process, is to be understood in the context of the customary unequal power relations between men and women.

Association of physical activity and cardiorespiratory function or BMI and body composition in preterm-born individuals: a systematic review.

Aim: To evaluate the association of physical activity (PA) and forced expiratory volume in one second (FEV1), peak oxygen consumption (pVO2), body mass index (BMI) and body composition in preterm-born individuals.

Methods: Cochrane Library, EMBASE, MEDLINE, AMED, ERIC, Web of Science and PsycInfo were searched with no restriction on language and date of publication from inception to January 2018. Data were extracted comparing preterm-born individuals with different frequencies of PA and the outcome of interest.

Comparison of diets for Largemouth and Smallmouth Bass in Eastern Lake Ontario using DNA barcoding and stable isotope analysis.

Largemouth (LMB: Micropterus salmoides) and Smallmouth Bass (SMB: Micropterus dolomieu) are important species in the recreational fisheries of the Laurentian Great Lakes. The invasion of the Round Goby (Neogobius melanostomus) into these lakes has changed several facets of black bass biology, but there is still much to learn about the relationship between these species. Previous dietary analyses have shown Round Goby to be important prey for bass, but have been limited by low visual identification rates of dissected stomach items.

Effects of p53-knockout in vascular smooth muscle cells on atherosclerosis in mice.

In vitro and in vivo evidence has indicated that the tumor suppressor, p53, may play a significant role in the regulation of atherosclerotic plaque formation. In vivo studies using global knockout mice models, however, have generated inconclusive results that do not address the roles of p53 in various cell types involved in atherosclerosis. In this study, we have specifically ablated p53 in vascular smooth muscle cells (VSMC) in the ApoE-/- mouse model to investigate the roles of p53 in VSMC in atherosclerotic plaque formation and stability.

Transgressive women don't deserve protection: young men's narratives of sexual violence against women in rural Papua New Guinea.

Sexual violence against women and girls is commonplace in Papua New Guinea (PNG). While the experiences of women are rightly given central place in institutional responses to sexual violence, the men who perpetrate violence are often overlooked, an oversight that undermines the effectiveness of prevention efforts. This paper draws on interviews conducted with young men as part of a qualitative longitudinal study of masculinity and male sexuality in a rural highland area of PNG.

The roles of akt isoforms in the regulation of podosome formation in fibroblasts and extracellular matrix invasion.

Mesenchymal cells employ actin-based membrane protrusions called podosomes and invadopodia for cross-tissue migration during normal human development such as embryogenesis and angiogenesis, and in diseases such as atherosclerosis plaque formation and cancer cell metastasis. The Akt isoforms, downstream effectors of phosphatidylinositol 3 kinase (PI3K), play crucial roles in cell migration and invasion, but their involvement in podosome formation and cell invasion is not known. In this study, we have used Akt1 and/or Akt2 knockout mouse embryonic fibroblasts and Akt3-targeted shRNA to determine the roles of the three Akt isoforms in Src and phorbol ester-induced podosome formation, and extracellular matrix (ECM) digestion.
