Parainfluenza virus 3 (PIV3) infection poses a substantial risk to vulnerable groups including infants, the elderly, and immunocompromised individuals, and lacks effective treatments or vaccines. This study focuses on targeting the hemagglutinin-neuraminidase (HN) protein, a structural glycoprotein of PIV3 critical for viral infection and egress. With the objective of targeting these activities of HN, we identified eight neutralizing human monoclonal antibodies (mAbs) with potent effects on viral neutralization, cell-cell fusion inhibition, and complement deposition.

Introduction: Central to neurosurgical care, neurosurgical education is particularly needed in low- and middle-income countries (LMICs), where opportunities for neurosurgical training are limited due to social and economic constraints and an inadequate workforce. The present paper aims (1) to evaluate the validity and usability of a cadaver-free hybrid system in the context of LMICs and (2) to report their learning needs and whether the courses meet those needs via a comprehensive survey.

Methods: From April to November 2021, a non-profit initiative consisting of a series of innovative cadaver-free courses based on virtual and practical training was organized.

Article Synopsis
  • COBRAs are a promising universal influenza vaccine that needs further study on how they trigger immune responses with different adjuvants.
  • In studies, various adjuvants, including AddaVax and AddaS03, were tested with two COBRAs specific to H1 and N1 subtypes.
  • AddaS03 was found to be the most effective adjuvant, producing high levels of antibodies in response to the vaccine candidates, particularly effective against the 2009 H1N1 virus.

Neuraminidase (NA) is an important surface protein on influenza virions, playing an essential role in the viral life cycle and being a key target of the immune system. Despite the importance of NA-based immunity, current vaccines are focused on the hemagglutinin (HA) protein as the target for protective antibodies, and the amount of NA is not standardized in virion-based vaccines. Antibodies targeting NA are predominantly protective, reducing infection severity and viral shedding.

Among circulating influenza viruses in humans, H3N2 viruses typically evolve faster than other subtypes and have caused disease in millions of people since emerging in 1968. Computationally optimized broadly reactive antigen (COBRA) technology is one strategy to broaden vaccine-elicited antibody responses among influenza subtypes. In this study, we determined the structural integrity of an H3N2 COBRA hemagglutinin (HA), TJ5, and we probed the antigenic profile of several H3N2 COBRA HAs by assessing recognition of these immunogens by human B cells from seasonally vaccinated human subjects.

Computationally optimized broadly reactive Ag (COBRA) hemagglutinin (HA) immunogens have previously been generated for several influenza subtypes to improve vaccine-elicited Ab breadth. As nearly all individuals have pre-existing immunity to influenza viruses, influenza-specific memory B cells will likely be recalled upon COBRA HA vaccination. We determined the epitope specificity and repertoire characteristics of pre-existing human B cells to H1 COBRA HA Ags.

The rapid development of nutrition science is embracing digital transformation to generate large amounts of data. Precision nutrition and "Big Data" place increasing demand for data repositories and visualization, which enhances the digital transformation. We defined the need for an integrated nutrition data platform as a web-based platform that can collect, store, track, analyze, monitor, and visually display key metrics in nutrition and health while allowing users to interact with visuals and download data provided in the platform.

Nutrient profiling systems (NPS) aim to discriminate the healthfulness of foods for front-of-package labelling, warning labels, taxation, company ratings and more. Existing NPS often assess relatively few nutrients and ingredients, use inconsistent criteria across food categories and have not incorporated the newest science. Here, we developed and validated an NPS, the Food Compass, to incorporate a broader range of food characteristics, attributes and uniform scoring principles.

The number of women in the medical field has increased in Africa over the last few decades, yet the underrepresentation of women within neurosurgery has been a recurrent theme. Of all surgical disciplines, neurosurgery is among the least equitable, and the rate of increase in female surgeons lags behind other surgical disciplines such as general surgery. This historical review provides an overview of the history of women in neurosurgery and their current status on the African continent.

Improving awareness and accessibility of healthy diets are key challenges for health professionals and policymakers alike. While the US government has been assessing and encouraging nutritious diets via the Dietary Guidelines for Americans (DGA) since 1980, the long-term sustainability, and thus availability, of those diets has received less attention. The 2015 Dietary Guidelines Advisory Committee (DGAC) examined the evidence on sustainable diets for the first time, but this topic was not included within the scope of work for the 2020 DGAC.
