#1
Hang Cao, Rosi Bissinger, Anja T Umbach, Meinrad Gawaz, Florian Lang
BACKGROUND/AIMS: The retinoid X receptor (RXRs) stimulator Bexarotene ((4-[1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthyl)ethynyl] benzoic acid) is used for the treatment of several malignancies. Bexarotene is at least in part effective by stimulation of apoptosis of tumor cells. Moreover, Bexarotene triggers eryptosis, the suicidal death of erythrocytes. Similar to erythrocytes, blood platelets lack nuclei but are nevertheless able to enter an apoptosis-like phenotype, characterized by caspase activation, cell shrinkage and cell membrane scrambling with phospha-tidylserine translocation to the cell surface...

BACKGROUND: Many older adults with depressive disorder manifest anxious distress. This longitudinal study examines the predictive value of worry as a maladaptive cognitive emotion regulation strategy, and resources necessary for successful emotion regulation (i.e., cognitive control and resting heart rate variability [HRV]) for the course of anxiety symptoms in depressed older adults. Moreover, it examines whether these emotion regulation variables moderate the impact of negative life events on severity of anxiety symptoms...

OBJECTIVE: Care coordinators may help manage care for children with chronic illness. Their role in pediatric epilepsy care is understudied. We aimed to qualitatively describe the content of a care coordination intervention for children with epilepsy. METHODS: We conducted nine semi-structured interviews and one focus group with care coordinators at a pediatric accountable care organization (ACO) in Ohio. The care coordinators used a modified version of a published care coordination checklist for children with epilepsy (Patel AD, 2014)...

BACKGROUND: Women protective service workers die by suicide at a higher rate than women workers in other occupational groups. However, no study has examined rates and correlates of suicidal thoughts and behaviors among women firefighters, despite the potential for these data to inform suicide screening, prevention, and intervention initiatives. The purpose of this study is to describe and compare pre-career and career rates of suicidal thoughts and behaviors and identify their sociodemographic and occupational correlates among women firefighters...

REVIEW
Kathleen M Schoch, Timothy M Miller
Multiple neurodegenerative diseases are characterized by single-protein dysfunction and aggregation. Treatment strategies for these diseases have often targeted downstream pathways to ameliorate consequences of protein dysfunction; however, targeting the source of that dysfunction, the affected protein itself, seems most judicious to achieve a highly effective therapeutic outcome. Antisense oligonucleotides (ASOs) are small sequences of DNA able to target RNA transcripts, resulting in reduced or modified protein expression...

Using a relativistic all-electron description and numerical atomic centered orbital basis set the performance of the G0W0 method on the electronic band gap of (TiO(2))n nanoparticles (n=1-20) is investigated. Results are presented for G0W0 on top of hybrid (PBE0 and a modified version with 12.5% of Fock exchange) functionals. The underestimation of the electronic band gap from Kohn-Sham orbital energies is corrected by the quasiparticle energies from G0W0 method which are consistent with the variational ΔSCF approach...

REVIEW
Alexander Panossian
Adaptogens are stress-response modifiers that increase an organism's nonspecific resistance to stress by increasing its ability to adapt and survive. The classical reductionist model is insufficiently complex to explain the mechanistic aspects of the physiological notion of "adaptability" and the adaptogenic activity of adaptogens. Here, I demonstrate that (1) the mechanisms of action of adaptogens are impossible to rationally describe using the reductionist concept of pharmacology, whereas the network pharmacology approach is the most suitable method; and (2) the principles of systems biology and pharmacological networks appear to be more suitable for conceptualizing adaptogen function and are applicable to any phytochemical...

Myeloproliferative neoplasms (MPNs) are a class of hematologic diseases characterized by aberrant proliferation of one or more myeloid lineages and progressive bone marrow fibrosis. In 2005, seminal work by multiple groups identified the JAK2V617F mutation in a significant fraction of MPN patients. Since that time, murine models of JAK2V617F have greatly enhanced the understanding of the role of aberrant JAK-STAT signaling in MPN pathogenesis and have provided an in vivo pre-clinical platform that can be used to develop novel therapies...

Traditional genome-wide scans for positive selection have mainly uncovered selective sweeps associated with monogenic traits. While selection on quantitative traits is much more common, very few signals have been detected because of their polygenic nature. We searched for positive selection signals underlying coronary artery disease (CAD) in worldwide populations, using novel approaches to quantify relationships between polygenic selection signals and CAD genetic risk. We identified new candidate adaptive loci that appear to have been directly modified by disease pressures given their significant associations with CAD genetic risk...

PURPOSE: Disease staging involves the assessment of disease severity or progression and is used for treatment selection. In diabetic retinopathy, disease staging using a wide area is more desirable than that using a limited area. We investigated if deep learning artificial intelligence (AI) could be used to grade diabetic retinopathy and determine treatment and prognosis. METHODS: The retrospective study analyzed 9,939 posterior pole photographs of 2,740 patients with diabetes...

BACKGROUND: MicroRNA-155 (miR-155) is known to be involved in autoimmune diseases, inflammation, and transplantation. However, its role in a warm hepatic ischemia-reperfusion (IR) model has not been fully elucidated. METHODS: Partial hepatic IR was performed in wild-type and miR-155-deficient mice treated with or without GdCl3, and then the serum transaminase concentration and histology were analyzed. Kupffer cells (KCs) were isolated from the liver after IR, and immunohistochemistry was used to evaluate activation and polarization...

Flavins, including flavin adenine dinucleotide (FAD), are fundamental catalytic cofactors responsible for the redox functionality of a diverse set of proteins. Alternatively, modified flavin analogues are rarely found in nature as their incorporation typically results in inactivation of flavoproteins, thus leading to the disruption of important cellular pathways. Here, we report that the fungal flavoenzyme formate oxidase (FOX) catalyzes the slow conversion of non-covalently bound FAD to 8-formyl FAD (8-fFAD), and that this conversion results in a nearly 10-fold increase in formate oxidase activity...

In order to provide orthogonal solvent processible surface modification and improve device stability of bulk-heterojunction polymer solar cells (PSCs), n-type semiconducting material naphthalene diimide (NDI) was chemically introduced on ITO surface as cathode interlayer (CIL) using 3-bromopropyltrimethoxysilane (BrTMS) as coupling agent. After modification, the work function of ITO can be decreased from 4.70 eV to 4.23 eV. The modified ITO cathode was applied in inverted PSCs based on PTB7-Th:PC71BM. With the CIL modification, a champion power conversion efficiency (PCE) of 5...
