DNA Damage Induced by Late Spring Sunlight in Antarctica.

Photochem Photobiol 2020 Jul 2. Epub 2020 Jul 2.

Depto. de Microbiologia, Instituto de Ciências Biomédicas, Universidade de São Paulo, São Paulo, SP, Brazil.

Sunlight ultraviolet (UV) radiation constitutes an important environmental genotoxic agent that organisms are exposed to, as it can damage DNA directly, generating pyrimidine dimers, and indirectly, generating oxidized bases and single-strand breaks (SSBs). These lesions can lead to mutations, triggering skin and eye disorders, including carcinogenesis and photoaging. Stratospheric ozone layer depletion, particularly in the Antarctic continent, predicts an uncertain scenario of UV incidence on the Earth in the next decades. Read More

Many of these have not been updated yet, and may never be, therefore, the main objectives of this paper are to develop an offline skin dose mapping application, which uses DICOM headers for the peak skin dose (PSD) assessment and to compare the PSD assessment results to XR-RV3 Gafchromic film for common IC procedures.

Comparative assessment of phenolic bioaccessibility from 100% grape juice and whole grapes.

Food Funct 2020 Jul 2. Epub 2020 Jul 2.

Plants for Human Health Institute, North Carolina State University, Kannapolis, NC, USA. and Department of Food Bioprocessing and Nutrition Sciences, North Carolina State University, Raleigh, NC, USA.

Juicing of grapes includes contact with phenolic rich seeds and skins that otherwise rely on maceration for phenolic release. To understand if 100% grape juice can provide a matrix with highly bioaccessible phenolics relative to whole fruit, differences in phenolic content and bioaccessibility from commonly consumed table, Concord (CG) and Niagara (NG) grapes and their 100% juices were compared. Phenolic contents in whole grapes and 100% juices were assayed by LC-MS prior to in vitro digestion to determine phenolic bioaccessibility. Read More

Mineralized Soft and Elastic Polymer Dots-Hydrogel for Flexible Self-Powered Electronic Skin Sensor.

ACS Appl Mater Interfaces 2020 Jul 2. Epub 2020 Jul 2.

We propose an integrated, self-powered, flexible electronic skin device containing an alginate-derived polymer dot (A-PD)-incorporated mineralized hydrogel-based energy-storage unit and a chitosan-derived n-type carbon dot (N-CD)-based solar cell for an energy-harvesting unit. This study demonstrates a unique architecture of mineralized hydrogel comprising of A-PD-incorporated poly(acrylic acid) (PAA)/CaCO3/laponite containing soft and sensitive layer, deposited with a polyaniline electrode to serve as an energy storage unit. The self-assembly was achieved through the ionic crosslinking between A-PD and PAA driven by the mineralization process, resulting in excellent dimensional stability and improved mechanical properties of the hydrogel.

Chilblain-like lesions during COVID-19 pandemic: a serological study on a case series.

Br J Dermatol 2020 Jul 1. Epub 2020 Jul 1.

Division of Dermatology, Santa Chiara Hospital, Trento, Italy.

The outbreak of chilblain-like lesions (CLL) coincidentally to the COVID-19 pandemic is a topic of great concern. SARS-CoV-2 has been hypothesized as the etiologic agent of CLL, on the basis of the temporal correlation between the "burst" of skin manifestations and the viral pandemic. However, the relationship between CLL and COVID-19 remains unclear, since authors failed to confirm the SARS-CoV-2 infection in these patients using a real-time reverse transcription polymerase chain reaction (rt-PCR) test from nasopharyngeal swabs, which seldom resulted positive.
