Estimation and Hypothesis Testing of Strain-Specific Vaccine Efficacy With Missing Strain Types With Application to a COVID-19 Vaccine Trial.

Based on data from a randomized, controlled vaccine efficacy trial, this article develops statistical methods for assessing vaccine efficacy (VE) to prevent COVID-19 infections by a discrete set of genetic strains of SARS-CoV-2. Strain-specific VE adjusting for possibly time-varying covariates is estimated using augmented inverse probability weighting to address missing viral genotypes under a competing risks model that allows separate baseline hazards for different risk groups. Hypothesis tests are developed to assess whether the vaccine provides at least a specified level of VE against some viral genotypes and whether VE varies across genotypes.

Cathodal Transcranial Direct Current Stimulation Does Not Change Implicit Associations Against Alcohol in Alcohol Use Disorder: A Preregistered Clinical Trial.

Addictive behaviour is shaped by the dynamic interaction of implicit, bottom-up and explicit, top-down cognitive processes. In alcohol use disorder (AUD), implicit alcohol-related associations have been shown to predict increased subsequent alcohol consumption and are linked to the risk of relapse. Explicit cognitive processes, exerting prefrontal top-down control, are particularly significant during the critical period following the decision to abstain.

A Museum Medicine Internship: Program Outline and Participants' Reflections of Its Impact on Their Veterinary Careers.

The Window on Animal Health at the North Carolina Museum of Natural Sciences hosts the VetPAC Museum Medicine Internship, an undergraduate student internship program founded in collaboration with the Veterinary Professions Advising Center at North Carolina State University.

Preserving the Biologically Coherent Generic Concept of , 'Plant Destroyer'.

is a long-established, well known and globally important genus of plant pathogens. Phylogenetic evidence has shown that the biologically distinct, obligate biotrophic downy mildews evolved from at least twice. Since, cladistically, this renders 'paraphyletic', it has been proposed that evolutionary clades be split into multiple genera (Runge et al.

Collateral blood vessels in stroke and ischemic disease: Formation, physiology, rarefaction, remodeling.

Collateral blood vessels are unique, naturally occurring endogenous bypass vessels that provide alternative pathways for oxygen delivery in obstructive arterial conditions and diseases. Surprisingly however, the capacity of the collateral circulation to provide protection varies greatly among individuals, resulting in a significant fraction having poor collateral circulation in their tissues. We recently reviewed evidence that the presence of naturally-occurring polymorphisms in genes that determine the number and diameter of collaterals that form during development (ie, genetic background), is a major contributor to this variation.

mir-276a Is Required for Muscle Development in and Regulates the FGF Receptor During the Migration of Nascent Myotubes in the Testis.

MicroRNAs function as post-transcriptional regulators in gene expression and control a broad range of biological processes in metazoans. The formation of multinucleated muscles is essential for locomotion, growth, and muscle repair. microRNAs have also emerged as important regulators for muscle development and function.

Multi-level barriers to equitable postpartum permanent contraception.

Background: There are several barriers to fulfillment of desired postpartum permanent contraception (PC). Prior research has primarily focused on the federal Medicaid sterilization policy as a barrier to PC; however, other barriers need to be examined.

Objectives: To explore the levels and intersections of barriers to postpartum PC that exist external to the Medicaid policy.

Arene and Heteroarene Functionalization Enabled by Organic Photoredox Catalysis.

ConspectusAromatic functionalization reactions are some of the most fundamental transformations in organic chemistry and have been a mainstay of chemical synthesis for over a century. Reactions such as electrophilic and nucleophilic aromatic substitution (EAS and SAr, respectively) represent the two most fundamental reaction classes for arene elaboration and still today typify the most utilized methods for aromatic functionalization. Despite the reliable reactivity accessed by these venerable transformations, the chemical space that can be accessed by EAS and SAr reactions is inherently limited due to the electronic requirements of the substrate.

The evolving landscape of vasculitis management: past, current and emerging.

Our understanding of ANCA vasculitis has advanced from discovery of putative auto-antibodies to a greater understanding of the myriad alterations of innate and adaptive immunity in this disease. The 21st International Vasculitis Workshop held in Barcelona served again as a forum for distributing and sharing advances in this field. B-cell and T-cell subsets are skewed in ANCA vasculitis patients, favoring a pro-inflammatory phenotype.

Emerging cell therapies in the vasculitis field.

ANCA vasculitis is a systemic autoimmune small-vessel vasculitis characterized by autoantibodies targeting either MPO or PR3. While patients with ANCA vasculitis are successfully treated with broad-spectrum immunosuppression, these treatments often leave patients vulnerable to infections. Research in the field has made positive gains in regards to understanding autoantigen specificity and immune cell subset involvement in disease pathogenesis, relapse and remission.
