A Prioritized List of Veterinary Clinical Presentations in Dogs, Cats, and Horses to Guide Curricular Content, Design, and Assessment.

The Association of American Veterinary Medical Colleges competency-based veterinary education (CBVE) framework can be used to guide curriculum and assessment design and is intended to prepare veterinary graduates for Day One of clinical practice. However, while the framework defines curricular outcomes in terms of demonstrable competencies, it does not define the specific knowledge, skills, and attitudes required to achieve those outcomes. In some human medical curricula, prioritized lists of clinical presentations guide curricular content, design, and assessment.

Agar lot-specific inhibition in the plating efficiency of yeast spores and cells.

The fission yeast Schizosaccharomyces pombe and the budding yeast Saccharomyces cerevisiae are highly diverged (530 mya), single-celled, model eukaryotic organisms. Scientists employ mating, meiosis, and the plating of ascospores and cells to generate strains with novel genotypes and to discover biological processes. Our three laboratories encountered independently sudden-onset, major impediments to such research.

Distance-dependent effects on CRISPR/Cas9-mediated genome editing in compromise efficiency and create unsought alleles.

Discrete DNA sites position meiotic recombination at hotspots. We sought to create four different, 15 bp long, candidate regulatory DNA sites within the reporter gene. Each effort employed a fission yeast-optimized CRISPR system (SpEDIT), optimal guide RNA, and one of four homologous recombination templates with 10 to 15 bp substitutions.

Eukaryotic Pif1 helicase unwinds G-quadruplex and dsDNA using a conserved wedge.

G-quadruplexes (G4s) formed by guanine-rich nucleic acids induce genome instability through impeding DNA replication fork progression. G4s are stable DNA structures, the unfolding of which require the functions of DNA helicases. Pif1 helicase binds preferentially to G4 DNA and plays multiple roles in maintaining genome stability, but the mechanism by which Pif1 unfolds G4s is poorly understood.

Purification of Native Dentilisin Complex from by Preparative Continuous Polyacrylamide Gel Electrophoresis and Functional Analysis by Gelatin Zymography.

Periodontal disease is characterized by the destruction of the hard and soft tissues comprising the periodontium. This destruction translates to a degradation of the extracellular matrices (ECM), mediated by bacterial proteases, host-derived matrix metalloproteinases (MMPs), and other proteases released by host tissues and immune cells. Bacterial pathogens interact with host tissue, triggering adverse cellular functions, including a heightened immune response, tissue destruction, and tissue migration.

Examining the Interplay between the Cognitive and Emotional Aspects of Gender Differences in Spatial Processing.

Women reliably perform worse than men on measures of spatial ability, particularly those involving mental rotation. At the same time, females also report higher levels of spatial anxiety than males. What remains unclear, however, is whether and in what ways gender differences in these cognitive and affective aspects of spatial processing may be interrelated.

DNA sequences and distinct mechanisms for and alleles of .

The gene of the fission yeast supports both positive and negative selection; consequently, this gene is widely employed as a powerful tool to study diverse biological processes. Here we report the DNA sequences of two functionally null alleles, and . The allele has a four bp duplication of bp +63 to +66 (5'-CAAG-3') within the ORF and the allele has a nonsynonymous substitution (G to A) at bp +679.

Irritability in Youths: A Critical Integrative Review.

Irritability, defined as proneness to anger that may impair an individual's functioning, is common in youths. There has been a recent upsurge in relevant research. The authors combine systematic and narrative review approaches to integrate the latest clinical and translational findings and provide suggestions for addressing research gaps.

Selinexor for the treatment of recurrent or metastatic salivary gland tumors: Results from the GEMS-001 clinical trial.

Objectives: We aimed to evaluate the activity of selinexor, an oral selective inhibitor of nuclear export, in patients with recurrent or metastatic salivary gland tumors (SGT).

Methods: GEMS-001 is an open-label Phase 2 study for patients with recurrent or metastatic SGT with two parts. In Part 1 of the protocol, patients had tumor samples profiled with targeted next generation sequencing as well as immunohistochemistry for androgen receptor, HER-2 and ALK.

Early life drought predicts components of adult body size in wild female baboons.

Objectives: In many taxa, adverse early-life environments are associated with reduced growth and smaller body size in adulthood. However, in wild primates, we know very little about whether, where, and to what degree trajectories are influenced by early adversity, or which types of early adversity matter most. Here, we use parallel-laser photogrammetry to assess inter-individual predictors of three measures of body size (leg length, forearm length, and shoulder-rump length) in a population of wild female baboons studied since birth.

A retrospective cohort study of the characteristics of unsuccessful operative vaginal deliveries.

Introduction: Unsuccessful operative vaginal delivery (OVD) is associated with high rates of materno-fetal morbidity. We aimed to examine institutional rates of unsuccessful OVDs (uOVD) and compare them with successful OVD (sOVD) in order to identify factors to aid patient selection and education.

Methods: A 6-month retrospective cohort study was performed on all unsuccessful and successful OVDs in a tertiary level maternity hospital in the Republic of Ireland.

Pre-validation of a reporter gene assay for oxidative stress for the rapid screening of nanobiomaterials.

Engineered nanomaterials have been found to induce oxidative stress. Cellular oxidative stress, in turn, can result in the induction of antioxidant and detoxification enzymes which are controlled by the nuclear erythroid 2-related factor 2 (NRF2) transcription factor. Here, we present the results of a pre-validation study which was conducted within the frame of BIORIMA ("biomaterial risk management") an EU-funded research and innovation project.

Monitoring helicase-catalyzed unwinding of multiple duplexes simultaneously.

Helicases catalyze the unwinding of duplex nucleic acids to aid a variety of cellular processes. Although helicases unwind duplex DNA in the same direction that they translocate on single-stranded DNA, forked duplexes provide opportunities to monitor unwinding by helicase monomers bound to each arm of the fork. The activity of the helicase bound to the displaced strand can be discerned alongside the helicase bound to the translocase strand using a forked substrate with accessible duplexes on both strands labeled with different fluorophores.

Solid Lipid Nanoparticles Loaded with Nisin (SLN-Nisin) are More Effective Than Free Nisin as Antimicrobial, Antibiofilm, and Anticancer Agents.

Bacteriocins are peptides produced by bacteria to inhibit the growth of other prokaryotes. Nisin is a bacteriocin widely used in the food industry and for biomedical applications. However, bacteriocins have some limitations, as they experience mechanisms of resistance, degradation by proteases, and suboptimal intracellular delivery.

Role and Regulation of Pif1 Family Helicases at the Replication Fork.

Pif1 helicases are a multifunctional family of DNA helicases that are important for many aspects of genomic stability in the nucleus and mitochondria. Pif1 helicases are conserved from bacteria to humans. Pif1 helicases play multiple roles at the replication fork, including promoting replication through many barriers such as G-quadruplex DNA, the rDNA replication fork barrier, tRNA genes, and R-loops.

Semen and serum platinum levels in cisplatin-treated survivors of germ cell cancer.

Background: Testicular cancer survivors often have impaired gonadal function possibly related to chemotherapy. Platinum is a heavy metal that can be detected at low levels in serum many years after treatment, it is not known whether platinum also persists in semen and if platinum persistence in semen is associated with impaired fertility.

Methods: Adult cisplatin-treated testicular cancer survivors were enrolled.

Remote synchronous toenail procedure training using a sausage model.

: Social distancing practices brought on by the COVID-19 pandemic have limited the ability of residency training programs to deliver procedure training via traditional in-person methods. Financial strains brought on by the pandemic also mean that fewer resources may be available to develop novel teaching processes. We sought to investigate a protocol meant to address the rising need for inexpensive procedure training that can be performed remotely or in a socially distanced manner.

A structural feature of Dda helicase which enhances displacement of streptavidin and trp repressor from DNA.

Helicases are molecular motors with many activities. They use the energy from ATP hydrolysis to unwind double-stranded nucleic acids while translocating on the single-stranded DNA. In addition to unwinding, many helicases are able to remove proteins from nucleic acids.

Predictive radiomics signature for treatment response to nivolumab in patients with advanced renal cell carcinoma.

Introduction: The anti-programmed cell death protein-1 (PD-1) immune checkpoint inhibitor nivolumab is currently approved for the treatment of patients with metastatic renal cell carcinoma (mRCC); approximately 25% of patients respond. We hypothesized that we could identify a biomarker of response using radiomics to train a machine learning classifier to predict nivolumab response outcomes.

Methods: Patients with mRCC of different histologies treated with nivolumab in a single institution between 2013 and 2017 were retrospectively identified.

Implementation and Effects of a Team-Based Quality Improvement Training Program Across a Health System: The Northwestern Medicine Academy for Quality and Safety Improvement.

Background: Professional organizations emphasize the need to train health care professionals in quality improvement (QI). Many reports of QI education programs involve small numbers of participants. Little is known about QI education programs on a larger scale and whether participants subsequently engage in QI activities.

Treponema denticola dentilisin triggered TLR2/MyD88 activation upregulates a tissue destructive program involving MMPs via Sp1 in human oral cells.

Periodontal disease is driven by dysbiosis in the oral microbiome, resulting in over-representation of species that induce the release of pro-inflammatory cytokines, chemokines, and tissue-remodeling matrix metalloproteinases (MMPs) in the periodontium. These chronic tissue-destructive inflammatory responses result in gradual loss of tooth-supporting alveolar bone. The oral spirochete Treponema denticola, is consistently found at significantly elevated levels in periodontal lesions.

Quality of patient-reported outcomes in oncology clinical trials using immune checkpoint inhibitors: A systematic review.

Background: There are limited data regarding the quality of patient-reported outcome (PRO) data in immune checkpoint inhibitor (ICI) clinical trial publications.

Methods: A systematic search of citations from various databases was conducted to identify prospective clinical trials involving ICI in advanced tumors from 2003 to 2020. A 30-point score was adapted from the CONSORT PRO extension statement to assess adherence to CONSORT PRO reporting.
