Fluorescence-barcoded cell lines stably expressing membrane-anchored influenza neuraminidases.

The discovery of broadly protective antibodies to the influenza virus neuraminidase (NA) has raised interest in NA as a vaccine target. However, recombinant, solubilized tetrameric NA ectodomains are often challenging to express and isolate, hindering the study of anti-NA humoral responses. To address this obstacle, we established a panel of 22 non-adherent cell lines stably expressing native, historical N1, N2, N3, N9, and NB NAs anchored on the cell surface.

Subjective Well-Being among African Americans: Findings from the National Survey of American Life.

Life satisfaction and happiness are related but distinct assessments of life quality with established links to sociodemographic and health factors. Despite a rich literature on quality of life, there remains a paucity of research on this topic among African Americans. This investigation explored (1) the sociodemographic correlates of life satisfaction and happiness and (2) how life satisfaction and happiness are related to health factors and adversity-relevant life circumstances.

Immunodominant extracellular loops of Treponema pallidum FadL outer membrane proteins elicit antibodies with opsonic and growth-inhibitory activities.

The global resurgence of syphilis has created a potent stimulus for vaccine development. To identify potentially protective antibodies against Treponema pallidum (TPA), we used Pyrococcus furiosus thioredoxin (PfTrx) to display extracellular loops (ECLs) from three TPA outer membrane protein families (outer membrane factors for efflux pumps, eight-stranded β-barrels, and FadLs) to assess their reactivity with immune rabbit serum (IRS). We identified five immunodominant loops from the FadL orthologs TP0856, TP0858 and TP0865 by immunoblotting and ELISA.

Potassium bicarbonate, not sodium bicarbonate, maintains acidosis-mediated bone dissolution.

Treatments for metabolic acidosis are not well studied; however, one treatment that is commonly used is sodium bicarbonate administration. Sodium bicarbonate has been shown to help reduce symptoms of metabolic acidosis, but its benefits for bone health remain uncertain. Potassium bicarbonate has become a potential new treatment due to its reduction in bone resorption markers, unlike sodium bicarbonate.

Allostatic Load, Educational Attainment, and Risk of Cancer Mortality Among US Men.

Importance: Health disparities among racial and ethnic minoritized populations, particularly for cancer mortality rates, remain a major public health concern. Men from underrepresented backgrounds (Black and Hispanic men, specifically) face the pervasive effects of discrimination in their daily lives, which also contribute to the complex associations among allostatic load (a marker of chronic stress), educational opportunities, and elevated risks of cancer mortality.

Objective: To elucidate the associations among educational attainment, allostatic load, and cancer mortality risk among men.
