Data on personal sun exposure over a period exceeding the immediate past days or weeks is typically self-reported in brief questionnaire items. The validity of such self-reporting of longer-term personal sun exposure, e.g. over a year, including detail on variation across seasons, has not previously been investigated. In a volunteer sample (n = 331) of Australian adults age 18 years and over, we assessed the 12-month reliability of sun exposure reported separately for each season, and its accuracy compared to a daily sun diary in the same season...

PURPOSE OF REVIEW: This review aims to summarize recent findings regarding the plasticity and fate switching among somatic and progenitor cells residing in the vascular wall of blood vessels in health and disease. RECENT FINDINGS: Cell lineage tracing methods have identified multiple origins of stem cells, macrophages, and matrix-producing cells that become mobilized after acute or chronic injury of cardiovascular tissues. These studies also revealed that in the disease environment, resident somatic cells become plastic, thereby changing their stereotypical identities to adopt proinflammatory and profibrotic phenotypes...

Differential mobility spectrometry (DMS) has been employed to separate isomeric species in several studies. Under the right conditions, factors such as separation voltage, temperature, the presence of chemical modifiers, and residence time can combine to provide unique signal channels for isomeric species. In this study, we examined a set of glycopeptide isomers, MUC5AC-3 and MUC5AC-13, which bear an N-acetyl-galactosamine (GalNAc) group on either threonine-3 or threonine-13. When analyzed as a mixture, the resulting MS and MS/MS spectra yield fragmentation patterns that cannot discern these convolved species...

PURPOSE: Parallel to increasing survival of breast cancer (BC) patients, a need has arisen to characterize the follow-up required to improve and maintain their health. Our study aimed to assess changes in lifestyle habits over time among the study population, compare compliance rates of selected primary and secondary prevention practices between long-term BC survivors and an age-matched comparison group, and identify factors associated with compliance to these practices. METHODS: The study population comprised 250 Israeli BC survivors, diagnosed with BC between 1999 and 2003, without evidence of disease after 8-12 years, and 250 women with no cancer history, individually matched to survivors by age and area of residence...

Biological invasions transport organisms to novel environments; but how does the translocation process influence movement patterns of the invader? Plausibly, the stress of encountering a novel environment, or of the transport process, might induce rapid dispersal from the release site-potentially enhancing (or reducing) invader success and spread. We investigated the effect of transportation and release to novel environments on dispersal-relevant traits of one of the world's most notorious invaders, the cane toad (Rhinella marina)...

Estimates of trends in birth weight may be useful in evaluating population health. We aimed to determine whether temporal changes in birth weight have occurred amongst 2.3 million neonates born in Guangzhou, China, during 2001-2015 and investigate the socioeconomic determinants of any changes. Trends in mean birth weight and annualized changes with the associated 95% confidence intervals (CIs) in the incidence of small for gestational age (SGA) and large for gestational age (LGA), defined as birth weight <10(th) or >90(th) centile respectively for gestational age and sex, were examined using linear and Poisson regression models...

REVIEW

Tissue adaptation is an intrinsic component of immune cell development, influencing both resistance to pathogens and tolerance. Chronically stimulated surfaces of the body, in particular the gut mucosa, are the major sites where immune cells traffic and reside. Their adaptation to these environments requires constant discrimination between natural stimulation coming from harmless microbiota and food, and pathogens that need to be cleared. This review will focus on the adaptation of lymphocytes to the gut mucosa, a highly specialized environment that can help us understand the plasticity of leukocytes arriving at various tissue sites and how tissue-related factors operate to shape immune cell fate and function...

Tissue-resident macrophages display varying phenotypic and functional properties that are largely specified by their local environment. One of these functions, phagocytosis, mediates the natural disposal of billions of cells, but its mechanisms and consequences within living tissues are poorly defined. Using a parabiosis-based strategy, we identified and isolated macrophages from multiple tissues as they phagocytosed blood-borne cellular material. Phagocytosis was circadianally regulated and mediated by distinct repertoires of receptors, opsonins, and transcription factors in macrophages from each tissue...

India accounts for one-fourth of the global tuberculosis (TB) burden. The National TB Program was started in 1962. Over a period of time, some lacunae such as poor case detection rate and incomplete treatment were observed. Later, the government formulated the Revised National Tuberculosis Control Program (RNTCP), which achieved a case detection rate of 70% and a cure rate of 85%. Still, the problem of relapse and defaulter cases persists. In 2014, 6% defaulter cases were reported from India. RNTCP has also focused on microlevel aspects, that is, newer diagnostics such as GenXpert, line probe assay and medicines such as bedaquiline for drug-resistant TB...

Neutrophils are the primary immune cells that respond to inflammation and combat microbial transgression. To thrive, the bacteria residing in their mammalian host have to withstand the antibactericidal responses of neutrophils. We report that enterobactin (Ent), a catecholate siderophore expressed by Escherichia coli, inhibited PMA-induced generation of reactive oxygen species (ROS) and neutrophil extracellular traps (NETs) in mouse and human neutrophils. Ent also impaired the degranulation of primary granules and inhibited phagocytosis and bactericidal activity of neutrophils, without affecting their migration and chemotaxis...

The gut-resident constituents of the microbiota protect the mucosa from invasive pathogens through engagement of both innate and adaptive branches of the immune system. They are also likely to provide systemic protection from pathogens, by enhancing host robustness and tolerance to the invasive microbes and by inducing immune responses that prevent their growth. These properties of commensal microbiota, particularly the capacity of some bacteria to induce diverse types of antigen-specific immune responses, raises the prospect that they could be deployed as vaccine vectors to generate effective local and systemic immunity to viral and bacterial pathogens...
