FDA: 7 Sunscreen Chemicals Enter Bloodstream After Use, But Don ’ t Abandon Sun Protection
(CNN) — After a single application, a total of seven chemicals commonly found in sunscreens can be absorbed into the bloodstream at levels that exceed safety thresholds, according to studies by the Center for Drug Evaluation and Research, an arm of the US Food and Drug Administration. “What is most alarming about these findings is that chemicals are absorbing into the body in significant amounts and the ingredients have not been fully tested for safety,” said David Andrews, a senior scientist for the Environmental Working Group, or EWG, a consumer organization which advocates for sunscreen safety. “...

Sunscreen Enters Bloodstream After Just One Day Of Use, Study Says
This study is the FDA’s way of showing sunscreen manufacturers they need to do the studies to see if chemical absorption poses health risks.” The need to screen According to the Skin Cancer Foundation, more Americans are diagnosed with skin cancer each year than all other cancers combined. Around the world, melanoma ranks as the 19th most common cancer in both men and women, says the World Cancer Research Fund. In the United States, sunscreens were originally approved as an over-the-counter solution to sunburn. They came in two types: one using chemical combos to filter the sun, the other using minerals to bloc...

Mass Cytometry Identifies Distinct Subsets of Regulatory T Cells and Natural Killer Cells Associated With High Risk for Type 1 Diabetes
In conclusion, we show that subpopulations of Treg and NK cells were increased in individuals positive for multiple autoantibodies before disease onset. To our knowledge, these are the first results showing alterations of a subset of Tregs and NK cells in individuals with high risk for T1D. Using a multidimensional phenotyping and unbiased clustering approach we were able to identify cell populations expressing markers which are not often analyzed in a conventional flow cytometry panel. This approach made it possible to find differences that otherwise would not have been detected. Our data provides new insight into disease...

Nutritional Heterogeneity Among Aspergillus fumigatus Strains Has Consequences for Virulence in a Strain- and Host-Dependent Manner
We examined the relationship between the metabolic processes of carbon catabolite repression (CCR), nitrogen catabolite repression (NCR) and virulence in a variety of A. fumigatus clinical isolates. A considerable amount of heterogeneity with respect to the degree of CCR and NCR was observed and a positive correlation between NCR and virulence in a neutropenic mouse model of pulmonary aspergillosis (PA) was found. Isolate Afs35 was selected for further analysis and compared to the reference strain A1163, with both strains presenting the same degree of virulence in a neutropenic mouse model of PA. Afs35 metabolome analysis ...
