Evaluation of the Second Edition of : A Customizable Curriculum for Apprentice-Style Undergraduate and Graduate Research Training Programs and Courses.

The second edition of (ER) is a collection of customizable active-learning activities, resources, and assessment and evaluation tools for use in undergraduate and graduate research training programs and courses. Results from two design and development research studies examining the effectiveness of the second edition of the ER curriculum and a 2-day ER facilitator training workshop are reported. Pilot testing of the second edition of the curriculum at 20 sites across the country (42 unique implementations) with 78 facilitators and 565 undergraduate and graduate research trainees provides evidence that the ER activities are clear and complete and that they were effective in helping trainees gain knowledge or improve their ability to do research.

Ultrastructural Characterization of Proteinuric Patients Predicts Clinical Outcomes.

Background: The analysis and reporting of glomerular features ascertained by electron microscopy are limited to few parameters with minimal predictive value, despite some contributions to disease diagnoses.

Methods: We investigated the prognostic value of 12 electron microscopy histologic and ultrastructural changes (descriptors) from the Nephrotic Syndrome Study Network (NEPTUNE) Digital Pathology Scoring System. Study pathologists scored 12 descriptors in NEPTUNE renal biopsies from 242 patients with minimal change disease or FSGS, with duplicate readings to evaluate reproducibility.

Social anxiety and age are associated with neural response to social evaluation during adolescence.

Adolescence is a sensitive period for the development of adaptive social behaviors and social anxiety, possibly due to aspects of brain development. However, research is needed to examine interactions among age, social anxiety, and social dynamics previously shown to influence neural responding. The current functional magnetic resonance imaging (fMRI) study examines brain function in 8-18 year-olds with varying levels of social anxiety.

Psychosis-associated DNA methylomic variation in Alzheimer's disease cortex.

Psychotic symptoms are a common and debilitating feature of Alzheimer's disease (AD) and are associated with a more rapid course of decline. Current evidence from postmortem and neuroimaging studies implicates frontal, temporal, and parietal lobes, with reported disruptions in monoaminergic pathways. However, the molecular mechanisms underlying this remain unclear.

Fluids affecting bladder urgency and lower urinary symptoms (FABULUS): methods and protocol for a randomized controlled trial.

Introduction And Hypothesis: We present the design of a randomized controlled trial, Fluids Affecting Bladder Urgency and Lower Urinary Symptoms (FABULUS), with the purpose of testing the common clinical advice of treating overactive bladder by eliminating potentially irritating beverages (PIBs) that are caffeinated, artificially sweetened, citric, or alcoholic. The primary hypothesis is that women taught to reduce PIBs will show less void frequency compared with a control group instructed in diet/exercise recommendations. Secondary outcomes include change in urgency symptoms and volume per void.

Variable Benefits of Antibody Induction by Kidney Allograft Type.

Background: Kidneys from acute renal failure (ARF), expanded criteria donors (ECD), and donation after cardiac death (DCD) donors are often discarded due to concerns for delayed graft function (DGF) and graft failure. Induction immunosuppression may be used to minimize these risks, but practices vary widely. Furthermore, little is known regarding national outcomes of transplant recipients receiving induction immunosuppression for receipt of high-risk kidneys.

Self-Perceived Improvement in Bladder Health After Viewing a Novel Tutorial on Knack Use: A Randomized Controlled Trial Pilot Study.

To test a novel bladder health tutorial on use of the Knack for overcoming bladder control challenges. The Knack-tutorial is a self-administered vignette-based instructional program on preempting bladder challenges in daily life (urgency, stress-leakage, or urge-leakage) through anticipatory, well-timed pelvic floor muscle contraction at the moment of challenge. This is a randomized controlled trial pilot test of 108 women with stress or mixed urinary incontinence.

Inland water bodies in China: Features discovered in the long-term satellite data.

Water bodies (WBs), such as lakes, ponds, and impoundments, provide essential ecosystem services for human society, yet their characteristics and changes over large areas remain elusive. Here we used unprecedented data layers derived from all Landsat images available between 1984 and 2015 to understand the overall characteristics and changes of WBs between 2 epochs (i.e.

Alzheimer's disease-associated (hydroxy)methylomic changes in the brain and blood.

Background: Late-onset Alzheimer's disease (AD) is a complex multifactorial affliction, the pathogenesis of which is thought to involve gene-environment interactions that might be captured in the epigenome. The present study investigated epigenome-wide patterns of DNA methylation (5-methylcytosine, 5mC) and hydroxymethylation (5-hydroxymethylcytosine, 5hmC), as well as the abundance of unmodified cytosine (UC), in relation to AD.

Results: We identified epigenetic differences in AD patients (n = 45) as compared to age-matched controls (n = 35) in the middle temporal gyrus, pertaining to genomic regions close to or overlapping with genes such as OXT (- 3.

A phase I dose finding study of intravenous voriconazole in pediatric patients undergoing hematopoietic cell transplantation.

To optimize voriconazole dosing in pediatric hematopoietic cell transplantation (HCT), we conducted a phase I study with a modified 3 + 3 dose-escalation followed by an expansion cohort at the maximum tolerated, minimum efficacious dose (MTD/MED). Patients ≤21 years who required voriconazole for prevention or treatment of an invasive fungal infection were assigned to three age groups. Of the 59 evaluable patients, 13 were <2 years, 23 were 2-11, and 23 were 12-21.

Reduced-Toxicity (BuFlu) Conditioning Is Better Tolerated but Has a Higher Second Transplantation Rate Compared to Myeloablative Conditioning (BuCy) in Children with Inherited Metabolic Disorders.

Hematopoietic stem cell transplantation (HCT) is a primary treatment for various inherited metabolic disorders (IMDs). Achieving stable and sustained engraftment while minimizing transplantation-related morbidity and mortality is critical to optimizing outcomes for IMDs. Traditional regimens have used myeloablative approaches, primarily busulfan and cyclophosphamide (BuCy), which is associated with significant regimen-related toxicity.

Oesophageal eosinophilia accompanies food allergy to hen egg white protein in young pigs.

Background: Esophagitis with eosinophilia, inflammation, and fibrosis represent a chronic condition in humans with food allergies.

Objective: In this investigation, we asked whether esophagitis with an eosinophilic component is observed in young pigs rendered allergic to hen egg white protein (HEWP).

Methods: Food allergy was induced in young pigs using two protocols.

Characterization of resistance to a potent D-peptide HIV entry inhibitor.

Background: PIE12-trimer is a highly potent D-peptide HIV-1 entry inhibitor that broadly targets group M isolates. It specifically binds the three identical conserved hydrophobic pockets at the base of the gp41 N-trimer with sub-femtomolar affinity. This extremely high affinity for the transiently exposed gp41 trimer provides a reserve of binding energy (resistance capacitor) to prevent the viral resistance pathway of stepwise accumulation of modest affinity-disrupting mutations.

Artificial fingerprints for cross-comparison of forensic DNA and protein recovery methods.

Quantitative genomic and proteomic evaluation of human latent fingerprint depositions represents a challenge within the forensic field, due to the high variability in the amount of DNA and protein initially deposited. To better assess recovery techniques for touch depositions, we present a method to produce simple and customizable artificial fingerprints. These artificial fingerprint samples include the primary components of a typical latent fingerprint, specifically sebaceous fluid, eccrine perspiration, extracellular DNA, and proteinaceous epidermal skin material (i.

Diagnosis and Management of Patients with the α-Gal Syndrome.

The galactose-α-1,3-galactose (α-Gal) syndrome has many novel features that are relevant to diagnosis and management. In most cases, the diagnosis can be made on a history of delayed allergic reactions to mammalian meat and the blood test for IgE to the oligosaccharide α-Gal. In general, the diagnosis also dictates the primary treatment, that is, avoiding mammalian meat and also dairy in some cases.

Structure Based Prediction of Neoantigen Immunogenicity.

The development of immunological therapies that incorporate peptide antigens presented to T cells by MHC proteins is a long sought-after goal, particularly for cancer, where mutated neoantigens are being explored as personalized cancer vaccines. Although neoantigens can be identified through sequencing, bioinformatics and mass spectrometry, identifying those which are immunogenic and able to promote tumor rejection remains a significant challenge. Here we examined the potential of high-resolution structural modeling followed by energetic scoring of structural features for predicting neoantigen immunogenicity.

Related and unrelated donor transplantation for β-thalassemia major: results of an international survey.

We studied 1110 patients with β-thalassemia major aged ≤25 years who received transplants with grafts from HLA-matched related (n = 677; 61%), HLA-mismatched related (n = 78; 7%), HLA-matched unrelated (n = 252; 23%), and HLA-mismatched unrelated (n = 103; 9%) donors between 2000 and 2016. Ninety percent of transplants were performed in the last decade. Eight-five percent of patients received ≥20 transfusions and 88% were inadequately chelated.
