Cancer patients may experience delayed skin effects of anti-PD-1 therapy

Jul 18 2018 - 00:07
Cancer patients receiving anti-PD-1 therapies who develop lesions, eczema, psoriasis, or other forms of auto-immune diseases affecting the skin may experience those adverse reactions on a delay -- sometimes even after treatment has concluded.

A carcinogen at the gym

Jul 18 2018 - 00:07
Gyms are places people go to get healthier. But nearly half the gyms in the U.S. contain a potentially addictive carcinogen -- tanning beds, report UConn researchers in the July 18 issue of JAMA Dermatology. Exercise reduces the risk of every cancer except melanoma. Tanning beds in gyms make tanning seem like part of a healthy lifestyle, undermine public health messaging and target a vulnerable population.

FEFU scientists reported on toxicity of carbon and silicon nanotubes and carbon nanofibers

Jul 18 2018 - 00:07
Nanoparticles with a wide range of applying, including medicine, damage cells of microalgae Heterosigma akashivo badly. This algae species is widely spread in the Russian Far East marine area. The acute toxic effect exhibited at concentrations of 100 mg/l of carbon nanotubes (CNTs) and silicon nanotubes (SiNTs) in the sea- or fresh water.

PCI patients discharged against medical advice twice as likely to be readmitted

Jul 18 2018 - 00:07
In a new study, researchers found discharge against medical advice as the strongest predictor of 30-day unplanned readmissions in heart attack patients. While only a small number of patients choose to discharge against medical advice following percutaneous coronary intervention (PCI), these patients are twice as likely to be readmitted to the hospital, according to the study published in JACC: Cardiovascular Interventions.

Innate stress

Jul 18 2018 - 00:07
A team of researchers from the Higher School of Economics and the RAS Vavilov Institute of General Genetics has been able to statistically monitor the impact of the monoamine oxidase A gene (MAOA) on the subjective evaluation of well-being among men. This work has been published in the article 'Association of MAOA-uVNTR Polymorphism with Subjective Well-Being in Men' and is the latest step towards an understanding of how genes can affect social phenomena.https://link.springer.com/article/10.1134/S1022795418050058

A safe and effective way to whiten teeth

Jul 18 2018 - 00:07
In the age of Instagram and Snapchat, everyone wants to have perfect pearly whites. To get a brighter smile, consumers can opt for over the counter teeth-whitening treatments or a trip to the dentist to have their teeth bleached professionally. But both types of treatments can harm teeth. According to an article published in ACS Biomaterials Science & Engineering, researchers have now developed a new, less destructive method.

Novel approach studies whale shark ages the best way -- while they are swimming

Jul 18 2018 - 00:07
A new study of whale sharks, using a novel approach to gathering data, shows these endangered animals can live longer and grow larger than previously believed.

New retinal ganglion cell subtypes emerge from single-cell RNA sequencing

Jul 18 2018 - 00:07
Single-cell sequencing technologies are filling in fine details in the catalog of life. Researchers at the University of Connecticut Health Center (UConn Health) and The Jackson Laboratory (JAX) have identified 40 subtypes of retinal ganglion cells (RGCs) along with the genetic markers and transcription factors that differentiate them.

'Nowcasting' beach water quality

Jul 18 2018 - 00:07
Arriving at your favorite beach only to discover it's closed because of bacterial contamination can be a bummer. But even worse would be unknowingly swimming in waters polluted with fecal material -- a very real possibility, given that current detection methods can require up to 24 hours to obtain results. Now, researchers reporting in the ACS journal Environmental Science & Technology have identified computer models that provide accurate short-term forecasts, or 'nowcasts,' of beach water quality.

Link found between bitter-taste sensitivity and cancer risk

Jul 18 2018 - 00:07
High bitter-taste sensitivity is associated with a significantly increased risk of cancer in older British women, according to researchers who conducted a unique study of 5,500 women whose diet, lifestyle and health has been tracked for about 20 years.

HIV infection doubles risk of heart disease, global study finds

Jul 18 2018 - 00:07
People infected with HIV are twice as likely to suffer from heart disease, research has found. Analysis of global figures reveals that HIV-associated cardiovascular disease has more than tripled in the past 20 years as more people are living longer with the virus. The greatest impact is in sub-Saharan Africa and Asia Pacific regions, with Swaziland, Botswana and Lesotho particularly affected.

Lateral gene transfer enables chemical protection of beetles against antagonistic fungi

Jul 18 2018 - 00:07
An international team of researchers has discovered that bacteria associated to Lagria villosa beetles can produce an antifungal substance very similar to one found in tunicates living in the marine environment. The researchers revealed that this commonality is likely explained by the transfer of genes between unrelated microorganisms.

Planck: final data from the mission lends support to the standard cosmological model

Jul 18 2018 - 00:07
With its increased reliability and its data on the polarisation of relic radiation, the Planck mission corroborates the standard cosmological model with unrivalled precision for these parameters, even if some anomalies still remain. For this work the Planck consortium called upon some three hundred researchers, in particular from CNRS, CNES (the French national space agency), CEA (the French Alternative Energies and Atomic Energy Commission) and several universities in France.

Allergies: Mugwort pollen as main source of airborne endotoxins

Jul 18 2018 - 00:07
Different airborne substances can cause respiratory problems for asthma sufferers. These include bacteria and their components, which can trigger inflammations. How they become airborne has not been fully explained up to now. A team from Technical University of Munich and Helmholtz Zentrum München has shown that pollen from the mugwort plant is the main vector for bacteria and that this combination renders the pollen more aggressive. This is not the case in certain Alpine regions.

Dementia could be detected via routinely collected data, new research shows

Jul 18 2018 - 00:07
A new machine-learning model that scans routinely collected NHS data has shown promising signs of being able to predict undiagnosed dementia in primary care, according to research by the University of Plymouth. The results from the feasibility study suggest that the model could significantly reduce the number of those living with undiagnosed dementia.

Old Theban port of Chalcis: A medieval maritime crossroads in Greece

Jul 18 2018 - 00:07
One CNRS researcher, in cooperation with Greek colleagues, has focused her attention on a widely disseminated style of ceramics called the 'main Middle Byzantine Production,' found in all four corners of the Mediterranean. The team's findings have just been published online by the Journal of Archaeological Science: Reports.

Compound identified that protects against neurodegeneration

Jul 18 2018 - 00:07
Researchers from the University of Liverpool have identified a new compound that protects against neurodegeneration in nematode worms. The discovery may enable novel treatments for human neurodegenerative diseases to be developed in the future.
