BACKGROUND: The psychosocial evaluation is an important part of the live organ donor evaluation process, yet this is not standardized across institutions. OBJECTIVE: This study was designed to prospectively test the reliability and validity of a semistructured psychosocial evaluation tool that was recently developed and reported in the literature (the Live Donor Assessment Tool [LDAT]). METHODS: A total of 248 live donor candidates who presented for evaluation were invited to participate in a study that involved the LDAT being scored as part of the standard psychosocial evaluation process; 222 provided informed consent...

BACKGROUND: Transitional care units aim to assist caregivers who cannot manage the care for persons with dementia who manifest behavioral and psychological symptoms of dementia (BPSD). However, there is a dearth in research on such care units. OBJECTIVE: The current study reviewed one specialized transitional unit to better understand the characteristics of the persons with dementia and behavioral symptoms entering such unit. The study also looked at the change in terms of (a) BPSD, (b) use of psychotropic medications and (c) function of the patients in this unit...

Cryptosporidiosis is a nationally notifiable gastrointestinal illness caused by parasitic protozoa of the genus Cryptosporidium, which can cause profuse, watery diarrhea that can last up to 2-3 weeks in immunocompetent patients and can lead to life-threatening wasting and malabsorption in immunocompromised patients. Fecal-oral transmission of Cryptosporidium oocysts, the parasite's infectious life stage, occurs via ingestion of contaminated recreational water, drinking water, or food, or following contact with infected persons or animals, particularly preweaned bovine calves (1)...

Under stress, metabolism is changing: specific up- or down-regulation of proteins and metabolites occurs as well as side-effects. Distinguishing specific stress-signaling metabolites (alarmones) from side-products (damage metabolites) is not trivial. One example is diadenosine tetraphosphate, Ap4A - a side-product of aminoacyl-tRNA synthetases found in all domains of life. The earliest observations suggested that Ap4A serves as an alarmone for heat stress in E. coli. However, despite 50 years of research, the signaling mechanisms associated with Ap4A remain unknown...

Kirchhoff's law of thermal radiation, relating emissivity and absorptance is commonly formulated for opaque bodies in thermodynamic equilibrium with the environment. However, in many systems of practical importance, both assumptions are often not satisfied. We revisit the century-old law and examine the limits of its applicability in an example of Er:YAG and Er:YLF dielectric crystals-potential radiation converters for thermophotovoltaic applications. The (80 at.%) Er:YAG crystal is opaque between 1.45 μm and 1...

DCs are necessary and sufficient for induction of allergic airway inflammation. CD11b+ DCs direct the underlying Th2 immunity, but debate surrounds the function of CD103+ DCs in lung immunity and asthma after an allergic challenge. We challenged Batf3-/- mice, which lacked lung CD103+ DCs, with the relevant allergen house dust mite (HDM) as a model to ascertain their role in asthma. We show that acute and chronic HDM exposure leads to defective Th1 immunity in Batf3-deficient mice. In addition, chronic HDM challenge in Batf3-/- mice results in increased Th2 and Th17 immune responses and exacerbated airway inflammation...

The contributions of the innate immune system to the development of pancreatic cancer are still ill defined. Inflammatory macrophages can initiate metaplasia of pancreatic acinar cells to a duct-like phenotype (acinar-to-ductal metaplasia [ADM]), which then gives rise to pancreatic intraepithelial neoplasia (PanIN) when oncogenic KRas is present. However, it remains unclear when and how this inflammatory macrophage population is replaced by tumor-promoting macrophages. Here, we demonstrate the presence of interleukin-13 (IL-13), which can convert inflammatory into Ym1+ alternatively activated macrophages, at ADM/PanIN lesions...

BACKGROUND: WINROP (weight, insulin-like growth factor 1, neonatal, retinopathy of prematurity) is a web-based retinopathy of prematurity (ROP) risk algorithm that uses postnatal weight gain as a surrogate of insulin-like growth factor-1 (IGF-1) to predict the risk of severe ROP in premature infants. The purpose of this study was to validate the web-based algorithm WINROP in detecting severe (type 1 or type 2) ROP in a North American cohort of infants. METHODS: The records of consecutive infants who underwent ROP examinations between 2008 and 2011 were reviewed retrospectively...

Within the Brachyura there are a variety of specialized holding mechanisms, which facilitate the close attachment of the highly reduced pleon underneath the cephalothorax. The most common mechanism in eubrachyurans, known as the press-button, consists of a sternal protrusion and a corresponding pleonal socket. Reports on the microstructural properties of the surface of these holding structures are scarce and patchy. In this study, the European Green Crab Carcinus maenas, is used as model to describe the microstructure of a typical press-button mechanism with the use of scanning electron microscopy and light microscopic histology...

The olivary pretectal nucleus (OPT) is a midbrain structure that receives reciprocal bilateral retinal projections, is involved in the pupillary light reflex, and connects reciprocally with the intergeniculate leaflet (IGL), a retinorecipient brain region that mediates behavioral responses to light pulses (i.e., masking) in diurnal Nile grass rats. Here, we lesioned the OPT and evaluated behavioral responses in grass rats to various lighting conditions, as well as their anxiety-like responses to light exposure...

Minichromosome maintenance protein (Mcm) 10 is a part of the eukaryotic replication machinery and highly conserved throughout evolution. As a multivalent DNA scaffold, Mcm10 coordinates the action of proteins that are indispensable for lagging strand synthesis, such as the replication clamp, proliferating cell nuclear antigen (PCNA). The binding between Mcm10 and PCNA serves an essential function during DNA elongation and is mediated by the ubiquitination of Mcm10. Here we map lysine 372 as the primary attachment site for ubiquitin on S...

Background: There is marked interest in using DNA based methods to detect antimicrobial resistance (AMR) with targeted polymerase chain reaction (PCR) approaches increasingly being incorporated into clinical care. Whole genome sequencing (WGS) could offer significant advantages over targeted PCR for AMR detection, particularly for species where mutations are major drivers of AMR. Methods: Illumina MiSeq WGS and broth microdilution (BMD) assays were performed on 90 bloodstream isolates of the four most common gram-negative bacteria causing bloodstream infections in neutropenic patients...

Estrogen deficiency causes bone loss as a result of microdamage, oxidative stress, and osteocyte apoptosis. A relationship between oxidative stress-induced apoptosis, c-Jun N-terminal kinase (JNK) activation, and expression of factors involved in bone remodeling has been demonstrated in osteocytes. However, the molecular regulation of these events in osteocytes treated with 17β-estradiol (17β-E2) remains unexplored. The MLO-Y4 murine osteocyte-like cell line was used as a model to study starvation-induced apoptosis and ROS production during 17β-E2 treatment...

Multiple Endocrine Neoplasia type 1 (MEN1) syndrome is a rare complex tumor-predisposing hereditary disorder, inherited in an autosomal dominant manner (OMIM 131100). MEN1 is characterized by tumors of the parathyroids, the neuroendocrine cells of the gastro-entero-pancreatic tract, and the anterior pituitary. The molecular mechanisms that control parathyroid tumorigenesis are still poorly understood. Here we studied the global microRNAs (miRNAs) expression profile in MEN1 parathyroid adenomas to understand the role of these regulatory factors in MEN1 parathyroid tumorigenesis...
