Impact of astaxanthin supplementation on markers of cardiometabolic health and tactical performance among firefighters.

Rationale: Firefighters are at risk for cardiovascular disease due to occupational-related inflammation, oxidative stress, and lifestyle practices. Astaxanthin (AX) possesses anti-inflammatory/antioxidant and purported ergogenic properties. This study examined the impact of supplementing the diet with 12 mg/d AX for four weeks on markers of inflammation, oxidative stress, cardiometabolic health, exercise capacity, and occupation-related performance in career firefighters.

Estimating the impact of vaccination: lessons learned in the first phase of the Vaccine Impact Modelling Consortium.

Estimates of the global health impact of immunisation are important for quantifying historical benefits as well as planning future investments and strategy. The Vaccine Impact Modelling Consortium (VIMC) was established in 2016 to provide reliable estimates of the health impact of immunisation. In this article we examine the consortium in its first five-year phase.

The perceptual span in dyslexic reading and visual search.

Many studies have attempted to identify the root cause of dyslexia. Different theories of dyslexia have proposed either a phonological, attentional, or visual deficit. While research has used eye-tracking to study dyslexia, only two previous studies have used the moving-window paradigm to explore the perceptual span in dyslexic reading, and none have done so in visual search.

"Important Enough to Show the World": Using Authentic Research Opportunities and Micropublications to Build Students' Science Identities.

Primarily undergraduate institutions (PUI) often struggle to provide authentic research opportunities that culminate in peer-reviewed publications due to "recipe-driven" lab courses and the comprehensive body of work necessary for traditional scientific publication. However, the advent of short-form, single-figure "micropublications" has created novel opportunities for early-career scientists to make and publish authentic scientific contributions on a scale and in a timespan compatible with their training periods. The purpose of this qualitative case study is to explore the benefits accrued by eight undergraduate and master's students who participated in authentic, small-scale research projects and disseminated their work as coauthors of peer-reviewed micropublications at a PUI.

Syndecans in hematopoietic cells and their niches.

Heparan sulfate proteoglycans are a family of glycoproteins that modulate cell signaling by binding growth factors and changing their bioavailability. Syndecans are a specific family of transmembrane heparan sulfate proteoglycans that regulate cell adhesion, migration, and signaling. In this review, we will summarize emerging evidence for the functions of syndecans in the normal and malignant blood systems and their microenvironments.
