Amino acids represent an important component in the diet of the Venus flytrap (Dionaea muscipula), and supply plants with much needed nitrogen resources upon capture of insect prey. Little is known about the significance of prey-derived carbon backbones of amino acids for the success of Dionaea's carnivorous life-style. The present study tracked changes in plant amino acid pools and their δ(13) C- and δ(15) N-signatures, after half of all traps per plant had been fed with contrasting amounts of double-labeled insect powder (0, 5, 10 and 20 mg per trap)...

AIM: This study evaluates the clinical performance of a novel tunnel-like surgical technique in the treatment of isolated deep intrabony defects. MATERIAL AND METHODS: Twelve patients presenting with at least one isolated deep intrabony defect received regenerative periodontal treatment with "entire papilla preservation" technique. Access to the intrabony defect for debridement was provided by a bevelled vertical releasing incision positioned in the buccal gingiva of the neighbouring interdental space...

The distal end of the eukaryotic flagellum/cilium is important for axonemal growth and signaling and has distinct biomechanical properties. Specific flagellum tip structures exist, yet their composition, dynamics, and functions are largely unknown. We used biochemical approaches to identify seven constituents of the flagella connector at the tip of an assembling trypanosome flagellum and three constituents of the axonemal capping structure at the tips of both assembling and mature flagella. Both tip structures contain evolutionarily conserved as well as kinetoplastid-specific proteins, and component assembly into the structures occurs very early during flagellum extension...

International adoptees need to cope with stressful transitions and to develop secure attachment with their caregivers at the same time. Although most children adopted from abroad adjust fine, they are at increased risk of psychological problems. We investigated whether both child and family-related factors are associated with later psychological problems and whether the length of time spent at home after adoption before daycare moderates these associations among internationally adopted children in Finland (FinAdo, Finnish Adoption Study)...

US government-funded early home visiting services are expanding significantly. The most widely implemented home visiting models target at-risk new mothers and their infants. Such home visiting programs typically aim to support infant-parent relationships; yet, such programs' effects on infant attachment quality per se are as yet untested. Given these programs' aims, and the crucial role of early attachments in human development, it is important to understand attachment processes in home visited families. The current, preliminary study examined 94 high-risk mother-infant dyads participating in a randomized evaluation of the Healthy Families Durham (HFD) home visiting program...

Continuous monitoring of an arterial pulse using a pressure sensor attached on the epidermis is an important technology for detecting the early onset of cardiovascular disease and assessing personal health status. Conventional pulse sensors have the capability of detecting human biosignals, but have significant drawbacks of power consumption issues that limit sustainable operation of wearable medical devices. Here, a self-powered piezoelectric pulse sensor is demonstrated to enable in vivo measurement of radial/carotid pulse signals in near-surface arteries...

BACKGROUND: During the neonatal resuscitation, careful oxygenation is needed. The use of pulse oximetry is recommended to evaluate the need for oxygenation, but it is not clear whether adequate peripheral perfusion is established to allow the evaluation of arterial oxygen saturation (SpO2). Additionally, there is no study of the changes in SpO2 immediately after birth in Japan, despite the indispensable need for definitive oxygenation criteria. METHODS: A prospective observational study was performed in neonates with gestational ages of 35-41 weeks...

INTRODUCTION: Plant-made virus-like particles (VLP) bearing influenza virus hemagglutinins (HA) are novel vaccine candidates that induce cross-reactive humoral and poly-functional T cell responses. To better understand the mechanisms that underlie this broad immunogenicity we studied early interactions of VLPs bearing either H1 (A/California/07/2009 (H1N1)) or H5 (A/Indonesia/05/2005 (H5N1)) with a human monocytoid cell line (U-937 cells) and human monocyte-derived macrophages (MDMs) as model antigen-presenting cells (APC)...

Segregation of homologous chromosomes during meiosis depends on their ability to reorganize within the nucleus, discriminate among potential partners, and stabilize pairwise associations through assembly of the synaptonemal complex (SC). Here we report a high-resolution time-course analysis of these key early events during Caenorhabditis elegans meiosis. Labeled nucleotides are incorporated specifically into the X chromosomes during the last two hours of S phase, a property we exploit to identify a highly synchronous cohort of nuclei...

BACKGROUND: Disorganised attachment patterns in infants have been linked to later psychopathology. Services have variable practices for identifying and providing interventions for families of children with disorganised attachment patterns, which is the attachment pattern leading to most future psychopathology. Several recent government reports have highlighted the need for better parenting interventions in at risk groups. OBJECTIVES: The objective of this review and meta-analysis was to evaluate the clinical effectiveness of available parenting interventions for families of children at high risk of developing, or already showing, a disorganised pattern of attachment...

There has been a growing interest in the role played by antioxidant enzymes in the regulation of endometrial function in mammals. However, little is known about enzymatic antioxidative pathways involved in conditioning the cyclic and early pregnant endometrium for conceptus attachment and implantation in domestic ruminants. We aimed to investigate changes in activities of superoxide dismutase 1 and 2 (SOD1, SOD2), glutathione peroxidase (GPX), glutathione reductase (GR) and catalase (CAT) in sheep caruncles (CAR) and intercaruncles (ICAR) endometrial tissues of cyclic and early pregnant ewes...

The comprehensive social reform and relaxation of religious regulation in mainland China have encouraged scholars to propose a revival thesis of religion, predicting a rising prevalence of religious adherence in the Reform Era. This study extends the revival thesis by focusing attention on people's subjective religiosity, and investigates age, period, and cohort effects on the transition in perceived importance of religion from 1990 to 2012. Capitalizing on the repeated cross-sectional data of the China sample in the World Values Survey, this study shows that (1) The senior population, relative to the younger counterpart, attaches greater importance to religion...

Infectious rotavirus particles are triple-layered, icosahedral assemblies. The outer layer proteins, VP4 (cleaved to VP8* and VP5*) and VP7, surround a transcriptionally competent, double-layer particle (DLP), which they deliver into the cytosol. During entry of rhesus rotavirus, VP8* interacts with cell-surface gangliosides, allowing engulfment into a membrane vesicle by a clathrin-independent process. Escape into the cytosol and outer-layer shedding depend on interaction of a hydrophobic surface on VP5* with the membrane bilayer and on a large-scale conformational change...

PURPOSE: Indirect inguinal hernia related to the presence of a patent processus vaginalis (PPV) in adult is estimated to be around 15%. Most surgeons would favor a standard anterior hernioplasty to minimize the potential risk of damaging the spermatic cord structures that are always intimately fused to the congenital peritoneal sac. This also means overlooking the potential benefit of alternative posterior techniques such as endoscopic totally extraperitoneal (TEP) repair that is known to offer faster recovery with reduced risk of developing chronic groin pain...

Mitotic arrest deficient 2 (Mad2) belongs to the spindle assembly checkpoint (SAC), a mechanism that blocks progression of the cell cycle until microtubule attachment to kinetochores is complete. It has been found to be involved in the resistance of cancer cells to "anti-mitotic" drugs such as paclitaxel. Mad2 controls meiotic progression, but its role during sea urchin development had never been investigated. Furthermore, the existence of a SAC in this species had never been proved. The present data show that a Mad2 protein, highly homologous to that of humans, is expressed in this species...

Zymoseptoria tritici causes Septoria leaf blotch of wheat. The prevailing paradigm of the Z. tritici-wheat interaction assumes fungal ingress through stomata within 24-48h, followed by days of symptomless infection. This is extrapolated from studies testing the mode of fungal ingress under optimal infection conditions. Here, we explicitly assess the timing of entry, using GFP-tagged Z. tritici. We show that early entry is comparatively rare, and extended epiphytic growth possible. We test the hypotheses that our data diverge from earlier studies due to: i...

Attachment theory has developed over many decades - and continues to develop. Its roots lie in several seminal publications of John Bowlby (the basis of attachment theory) and Mary D. S. Ainsworth (the notion of individual differences in attachment). This paper identifies the prescient contributions of these early publications and two processes (a long-term dialogue and reflection on discrepancy) that underlay emergent theory. Because I was a student of Ainsworth when both attachment theory and individual differences in attachment organization were becoming better known, I offer some of my recollections of that period, suggesting how that period may have affected current work in attachment...

The history of Chinese medicine is still widely imagined in terms dictated by the discourse of modernity, that is as 'traditional' and 'Chinese.' And yet, so as to be intelligible to us moderns, it must simultaneously be framed through categories that make it comparable somehow to the 'West' and the 'modern' from which it is said to be essentially different. This is accomplished, for instance, by viewing Chinese medicine as fundamentally shaped by cosmological thinking, as focusing on process rather than matter, and as forever hampered by attachments to the past even when it tries to innovate...

Bromobenzene (BrB), a hydrophobic, recalcitrant organic compound, is listed by the environmental protection agencies as an environmental and marine pollutant having hepatotoxic, mutagenic, teratogenic, and carcinogenic effects. The tropical marine yeast Yarrowia lipolytica 3589 was seen to grow aerobically on BrB and displayed a maximum growth rate (μmax) of 0.04 h(-1). Furthermore, we also observed an increase in cell size and sedimentation velocity for the cells grown on BrB as compared to the glucose grown cells...
