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 block the sun such as titanium dioxide or zinc oxide, which leave the tell-tale white coating. Not wanting to sport a white tint, the popularity of the chemical sunscreens soared. Because of the way they were used at the time, there wasn’t a lot of concern about a potential health impact. But that soon changed, and the FDA began to ask the industry for safety testing, said David Andrews, senior scientist at EWG. “They were originally used in small quantities to prevent sunburn on vacation,” Andrews said. “Now they recommend applying these every day, applying them to large parts of your body. And the FDA began raising concerns.” A small study of sunscreen chemicals The new FDA study enrolled 24 healthy volunteers who were randomly assigned to a spray or lotion sunscreen that contained avobenzone, oxybenzone, or octocrylene as ingredi...

Authors: Li N, Guo X, Liu L, Wang L, Cheng R Abstract Objective: To investigate the regulatory mechanism of miR-204 on proliferation, apoptosis and autophagy of cervical cancer cells. Methods: The expression of miR-204 in cervical cancer tissues and cell lines was detected by real-time PCR. Cell viability and apoptosis were detected by MTT and flow cytometry, respectively. Protein expression of Bcl-2, Bax, Caspase-3 and LC3I/II in C33A cells after transfection was detected by Western blot assay. The interaction between miR-204 and ATF2 was verified by Targetscan online prediction, dual-luciferase assay and Western ...

In this study, our purpose was to investigate the methylation status of ACE and explored its prognostic value in CRC. The expression of ACE was detected by quantitative real-time polymerase chain reaction (qRT-PCR) analysis while the methylation status of ACE was measured via methylation-specific polymerase chain reaction (MSP). The result demonstrated that ACE expression was up-regulated in tumour tissues and HT-29 cells compared with the controls. ACE was also confirmed to be hypomethylated in CRC. Next, we evaluated the influence of ACE hypomethylation on cell growth. It was proved to be a favourable factor for the cell...

Publication date: October 2019Source: Materials Science in Semiconductor Processing, Volume 101Author(s): Ozlem Altintas YildirimAbstractCopper doped zinc oxide (Cu:ZnO) nanonails with uniformly distributed Cu ions through the nail structure were synthesized via a vapor-liquid-solid technique using seed Cu:ZnO nanoparticles. The seed nanoparticles were prepared with a simple precipitation method. The structure and morphology of nanonails and the distribution of Cu ions were investigated using X-ray diffraction, electron energy loss spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM) and...

In this study, we have successfully doped hydroxyapatite (HA) with zinc (Zn2+), sulphate (SO42−) and fluoride (F−) ions to develop a new composition of bioceramic, Ca10-x Znx(PO4)6-y(SO4)y(OH)2-z-yFz(SO4)y, (x = 0, 0.2, 0.6, 1.0, y = 0, 0.5 and z = 0,1.0 mol), using wet precipitation method. The obtained materials were analysed using XRD, FTIR, FESEM, and XPS techniques to investigate the phase purity, particle morphology and elemental composition, respectively. A model anticancer drug (Doxorubicin, DOX) was loaded onto the surface of the Zn/SO4-FHA materials. About 100% loading of DOX with a cont...

We retrospectively investigated the poor prognostic factors at discharge in elderly patients aged 75 years or older admitted to hospital with mild TBI. We continuously enrolled 83 patients aged 75 years or older with mild TBI, in a private general Japanese hospital. The Glasgow Coma Scale scores on admission were within the range of 13–1...

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

In this study, we identified 37 genus-level core bacteria from feces of 101 healthy mice with different ages, sexes, and mouse strains in three previous studies. They collectively represented nearly half of the total sequences, and predominantly included carbohydrate- and amino acids-metabolizing bacteria and immunomodulatory bacteria. Among them, Anaerostipes indwelt the gut of all healthy mice. Co-abundance analysis showed that these core genera were clustered into five groups (Group C1–C5), which were ecologically related. For example, the abundances of Group C2 including probiotics Bifidobacterium and Lactobacill...

In this study, the gut microbiota of 30 LC patients and 30 healthy controls were examined via next-generation sequencing of 16S rRNA and analyzed for diversity and biomarkers. We found that there was no decrease in significant microbial diversity (alpha diversity) in LC patients compared to controls (P observed = 0.1422), while the composition (beta diversity) differed significantly between patients and controls (phylum [stress = 0.153], class [stress = 0.16], order [stress = 0.146], family [stress = 0.153]). Controls had a higher abundance of the bacterial phylum Actinobacteria and genus Bifidobacterium, while patients wi...
