Ionic Hydrogels Based Wearable Sensors to Monitor the Solar Radiation Dose for Vitamin D Production and Sunburn Prevention.

ACS Appl Mater Interfaces 2021 Sep 15. Epub 2021 Sep 15.

Key Laboratory of Advanced Textile Materials & Manufacturing Technology, Ministry of Education, Zhejiang Sci-Tech University, 928 Second Avenue, 310018 Hangzhou, China.

Wearable solar radiation sensors based on ionic hydrogels are facilely prepared to simultaneously monitor the radiation dose for the production of vitamin D and the prevention of sunburn. Tetramethylethylenediamine (TEMED) is neutralized with acrylic acid (AA) to obtain tetramethylethylenediamine acrylate (TEMEDA), which is further polymerized with acrylamide by a free radical reaction. By simply adding MB or NR during the polymerization, the final obtained ionic hydrogels can indicate solar radiation. Read More

Corroles: The Hitherto Elusive Parent Macrocycle and its Metal Complexes.

Angew Chem Int Ed Engl 2021 Sep 15. Epub 2021 Sep 15.

Technion Israel Institute of Technology, Chemistry, ISRAEL.

The science and technology of corroles, macrocycles that owe their name to the cobalt-chelating prosthetic group of Vitamin B12 and share numerous features with the iron-chelating porphyrin present in heme proteins/enzymes, constantly crosses new boundaries ever since stable derivatives became easily accessible. Particularly important is the increasing utilization of corroles and the corresponding metal complexes for the benefit of mankind, in terms of new drug candidates for treating various diseases and as catalysts for sustainable energy relevant processes. One still unmet challenge is to gain access to the plain macrocycle, as to allow for a full elucidation of the most fundamental properties of corroles. Read More

School of Sports and Exercise Sciences, Faculty of Science, Liverpool John Moores University, IM Marsh Campus, Barkhill Road, Liverpool L17 6AF, United Kingdom.

Individuals with discordantly high ApoB to LDL-C levels carry a higher risk of atherosclerotic cardiovascular disease compared to those with average or discordantly low ApoB to LDL-C. We aimed to determine associations between ApoB and LDL-C discordance in relation to nutrient patterns (NPs) using National Health and Nutrition Examination Survey data. Participants were grouped by established LDL-C and ApoB cut-offs (Group 1: Low ApoB/Low LDL-C, Group 2: Low ApoB/High LDL-C, Group 3: High ApoB/Low LDL-C, Group 4: High ApoB/High LDL-C). Read More

Causal risk and protective factors in rheumatoid arthritis: A genetic update.

J Transl Autoimmun 2021 3;4:100119. Epub 2021 Sep 3.

Central Research Laboratory, Kazan State Medical Academy, Kazan, Russia.

The characterization of risk and protective factors in complex diseases such as rheumatoid arthritis (RA) has evolved from epidemiological studies, which test association, to the use of Mendelian randomization approaches, which test direct relationships. Indeed, direct associations with the mucosal origin of RA are retrieved with periodontal disease ( and predominantly), interstitial lung involvement, tobacco smoking and air pollutants. Next, factors directly associated with an acquired immune response include genetic factors (HLA DRB1, PTPN22), capacity to produce anti-modified protein antibodies (AMPA), and relatives with a history of autoimmune diseases.

Oral delivery of proteins and peptides: Challenges, status quo and future perspectives.

Acta Pharm Sin B 2021 Aug 29;11(8):2416-2448. Epub 2021 Apr 29.

Shanghai Skin Disease Hospital, Tongji University School of Medicine, Shanghai 200443, China.

Proteins and peptides (PPs) have gradually become more attractive therapeutic molecules than small molecular drugs due to their high selectivity and efficacy, but fewer side effects. Owing to the poor stability and limited permeability through gastrointestinal (GI) tract and epithelia, the therapeutic PPs are usually administered by parenteral route. Given the big demand for oral administration in clinical use, a variety of researches focused on developing new technologies to overcome GI barriers of PPs, such as enteric coating, enzyme inhibitors, permeation enhancers, nanoparticles, as well as intestinal microdevices.

Wait-there's evidence for that? Integrative medicine treatments for major depressive disorder.

Int J Psychiatry Med 2021 Sep;56(5):334-343

Beaumont Grosse Pointe Family Medicine Residency, Grosse Pointe, MI, USA.

Depression is one of the most common mental health disorders and currently affects over 17 million Americans. Up to two-thirds of patients with depression in the United States will seek complementary and alternative or integrative medical treatments and thus medical providers who treat depression should understand that many integrative medical treatments have evidence of efficacy either as monotherapies or as add-on adjuncts to other treatments. This review references guidelines from the Canadian Network for Mood and Anxiety Treatments and Michigan Medicine, along with an updated literature review, to provide a framework for reviewing medications or herbal formulation, as well as other therapies, which have evidence in the treatment of depression.
