The common cuckoo (Cuculus canorus) is an avian brood parasite, laying its eggs in the nests of other bird species, where these hosts incubate the parasitic eggs, feed and rear the nestlings. The appearance of a cuckoo egg in a host nest may change the bacterial community in the nest. This may have consequences on the hatchability of host eggs, even when hosts reject the parasitic egg, typically within six days after parasitism. The present study revealed the bacterial community of cuckoo eggshells and those of the great reed warbler (Acrocephalus arundinaceus), one of the main hosts of cuckoos...

BACKGROUND: Does performing pre-employment hair drug testing subsequently affect the prevalence of positive random and postaccident urine drug tests? METHODS: This cross-sectional study was designed to evaluate the prevalence of positive postaccident and random workplace urine drug tests for companies that perform pre-employment hair and urine drug testing to companies that only perform pre-employment urine drug testing. RESULTS: Fisher exact test of independence indicated no significant difference between pre-employment hair drug testing and overall US Department of Transportation random and postaccident urine drug test positivity rates...

PURPOSE: To evaluate the probability of survival and failure modes of different external hexagon connection systems restored with anterior cement-retained single-unit crowns. The postulated null hypothesis was that there would be no differences under accelerated life testing. MATERIALS AND METHODS: Fifty-four external hexagon dental implants (∼4 mm diameter) were used for single cement-retained crown replacement and divided into 3 groups: (3i) Full OSSEOTITE, Biomet 3i (n = 18); (OL) OEX P4, Osseolife Implants (n = 18); and (IL) Unihex, Intra-Lock International (n = 18)...

Hepatic ischemia-reperfusion injury (IRI) represents a major risk factor of early graft dysfunction and acute/chronic rejection as well as a key obstacle to expanding the donor pool in orthotopic liver transplantation (OLT). Although glucocorticoid receptor (GR) signaling may enhance cytoprotective programs, clinical use of glucocorticoid is limited due to adverse effects, while clinical relevance of GR-facilitated cytoprotection in OLT remains unknown. We aimed to evaluate the significance of hepatic GR in clinical OLT and verify the impact of recombinant human relaxin (rhRLX), which may function as GR agonist in tissue/disease-specific manner...

Intimate partner violence (IPV) perpetration is often preceded by perceived interpersonal provocations such as slights, insults, and rejections. Yet the neural mechanisms that link provocation to IPV remain unclear. In the context of interactions with strangers, the medial prefrontal cortex (MPFC) has been repeatedly shown to respond to provocation, with more dorsal activation associated with more aggressive reactions and more ventral activation associated with less aggressive reactions. We used functional brain imaging to test whether this dorsal-ventral MPFC reactivity gradient would also correlate with greater aggression towards an unexamined target: intimate partners...

PORPUSE: Sudden cardiac death (SCD) is an important post-transplant problem being responsible for approximately 10% of deaths. We conducted a systematic review and meta-analysis to evaluate incidence and predictors of post-heart transplant SCD, and use of implantable cardiac defibrillator (ICD). METHODS: Citations were identified in electronic databases and references of included studies. Observational studies on adults reporting on incidence and predictors of post-transplant SCD and ICD use were selected...

The cost to individuals and to society of psychopathology that emerges in childhood is substantial. Children whose problems are undiagnosed or inadequately treated struggle in school, experience rejection by peers, and become a source of stress for caregivers and teachers. As adults, their mental health problems tend to recur and their cognitive difficulties persist. Clinicians hold a well-founded belief that early identification of children who are at risk for psychopathology is the key to prevention.

A study of ice formation in stationary turbulent conditions is carried out in various limit regimes of crystal growth, supercooling, and ice entrainment at the water surface. Analytical expressions for the temperature, salinity, and ice concentration mean profiles are provided, and the role of fluctuations in ice production is numerically quantified. Lower bounds on the ratio of sensible heat flux to latent heat flux to the atmosphere are derived and their dependence on key parameters such as salt rejection in freezing and ice entrainment in the water column is elucidated...

Simplicial complexes are now a popular alternative to networks when it comes to describing the structure of complex systems, primarily because they encode multinode interactions explicitly. With this new description comes the need for principled null models that allow for easy comparison with empirical data. We propose a natural candidate, the simplicial configuration model. The core of our contribution is an efficient and uniform Markov chain Monte Carlo sampler for this model. We demonstrate its usefulness in a short case study by investigating the topology of three real systems and their randomized counterparts (using their Betti numbers)...

BACKGROUND: Despite effective antiviral treatment, hundreds of kidneys from deceased donors with hepatitis C virus (HCV) are discarded annually. Little is known about the determinants of willingness to accept HCV-infected kidneys among HCV-negative patients. METHODS: At 2 centers, 189 patients undergoing initial or reevaluation for transplant made 12 hypothetical decisions about accepting HCV-infected kidneys in which we systematically varied expected HCV cure rate, allograft quality and wait-time for an uninfected kidney...

BACKGROUND: Kidney transplantation holds much promise as a treatment of choice for patients with end stage kidney disease. The impact of cold ischemia time (CIT) on acute renal transplant rejection (ARTR) remains to be fully studied in a large cohort of renal transplant patients. METHODS: From the Organ Procurement and Transplantation Network database, we analyzed 63,798 deceased donor renal transplants performed between 2000-2010. We assessed the association between CIT and ARTR...

Inferential statistics relies heavily on the central limit theorem and the related law of large numbers. According to the central limit theorem, regardless of the distribution of the source population, a sample estimate of that population will have a normal distribution, but only if the sample is large enough. The related law of large numbers holds that the central limit theorem is valid as random samples become large enough, usually defined as an n ≥ 30. In research-related hypothesis testing, the term "statistically significant" is used to describe when an observed difference or association has met a certain threshold...

BACKGROUND: Hepatic progenitor cells (HPC) are induced following liver injury to facilitate regeneration. Acute cellular rejection (ACR) is a common complication after liver transplantation as a result of immune-mediated liver injury. In this study we characterized HPC phenotype in liver allograft biopsy with ACR. We also explored the correlation between expression HPC immunophenotype and clinicopathological parameters. METHODS: Forty-four liver allograft biopsies performed between 2008-2016 in a single center with histologically proven ACR were examined for immunohistochemical expression of HPC markers CK19 and Sox9...

Maternal behavior is known to influence the behavioral development of young. Recently, it was demonstrated that maternal behavior also differed according to sex chicks and brood sex composition. So, here, we explored if these factors influenced behavioral development of chicks quail when they were brooded, and what characteristics of chicks and foster females could best explain this development. We studied three sets of chick pairs brooded by foster females: unisex male, unisex female, and mixed broods. We found that both emotivity profile and sociality depended on the sex: females were more reactive and less social than males...

We report a case of capillary leak that developed during treatment of antibody-mediated rejection in a kidney transplant recipient. A 53-year-old female transplant recipient experienced an increase in serum creatinine from 1.1 to 1.8 mg/dL. Antibody-mediated rejection was diagnosed by graft biopsy. She was treated with five plasmapheresis sessions (on alternate days with albumin replacement), five doses of immunoglobulin (5 g/dose at 100 mg/kg), a single dose of rituximab (500 mg), and four doses of bortezomib on days 1, 4, 7, and 10 (1...

Introduction: Being able to counter immune-mediated rejection has for decades been the single largest obstacle for the progress of vascular composite allotransplantation (VCA). The human immune system performs the key role of differentiating the 'self ' from the 'non-self '. This, although is quintessential to eliminate or resist infections, also resists the acceptance of an allograft which it promptly recognises as 'non-self'. Materials and Methods: Pre-operative evaluation of the recipient evaluation included immunological assessment in the form of panel reactive antibodies (PRA), human leucocyte antigen (HLA) typing, donor-specific antibody detection assays (DSA) and complement-dependent cytotoxicity assays (CDC)...

Safe and effective conflict resolution is critical for survival and reproduction. Theoretical models describe how animals resolve conflict by assessing their own and/or their opponent's ability (resource holding potential, RHP), yet experimental tests of these models are often inconclusive. Recent reviews have suggested this uncertainty could be alleviated by using multiple approaches to test assessment models. The mantis shrimp Neogonodactylus bredini presents visual displays and ritualistically exchanges high-force strikes during territorial contests...

The last large marsupial carnivores-the Tasmanian devil (Sarcophilis harrisii) and thylacine (Thylacinus cynocephalus)-went extinct on mainland Australia during the mid-Holocene. Based on the youngest fossil dates (approx. 3500 years before present, BP), these extinctions are often considered synchronous and driven by a common cause. However, many published devil dates have recently been rejected as unreliable, shifting the youngest mainland fossil age to 25 500 years BP and challenging the synchronous-extinction hypothesis...
