Indeed, the useful predictions generated by the present computational models are of immense importance and could further speed up the anticancer drug development in the near future.Developing efficient catalysts for the conversion of CO2 into fuels and value-added chemicals is of great significance to relieve the growing energy crisis and global warming. With the assistance of DFT calculations, it was found that, different from Al12 X (X=Be, Al, and C), the alkali-metal-like superatom Al12 P prefers to combine with CO2 via a bidentate double oxygen coordination, yielding a stable Al12 P(η2 -O2 C) complex containing an activated radical anion of CO2 (i.e., CO2.- ). Thereby, this compound could not only participate in the subsequent cycloaddition reaction with propylene oxide but also initiate the radical reaction with hydrogen gas to form high-value chemicals, revealing that Al12 P can play an important role in catalyzing these conversion reactions. Considering that Al12 P has been produced in laboratory and is capable of absorbing visible light to drive the activation and transformation of CO2 , it is anticipated that this work could guide the discovery of additional superatom catalysts for CO2 transformation and open up a new research field of superatom catalysis.

Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatologic disease of childhood. The various subtypes of JIA differ in clinical features and treatments. The aim of this study was to analyze the frequency of JIA subtypes, patient demographic and clinical features, as well as the rates of macrophage activation syndrome, uveitis, and remission in Turkish JIA patients treated at a single center, and to compare the findings to those in the literature.

The files of all JIA patients treated at our pediatric rheumatology department between January 2017 and January 2019 were retrospectively reviewed. Patient demographic, clinical, and laboratory data were obtained from the patients' files and hospital database.

The study included 305 patients (180 females) with a mean age at onset of 7.83 ± 4.62 years. Among all the JIA subtypes, the most frequent was oligoarthritis (41.6%), followed by enthesitis-related arthritis (29.2%), rheumatoid factor (RF)-negative polyarthritis (13.4%) systemic arthritis (9.5%), RF-positive polyarthritis (2.6%), psoriatic arthritis (2.0%), and undifferentiated arthritis (1.6%). At the time of data collection 278 patients (91.0%) were in remission, whereas 27 patients (9.0%) had active disease. Macrophage activation syndrome developed in 12 of the 29 (41.0%) systemic arthritis. Uveitis was noted in 32 (10.0%) patients. CBR-470-1 Biological agents were administered in 142 of the patients.

The available data indicate that JIA as a whole is a heterogeneous disease with significant variability in course and long-term outcome. As such, each patient should be evaluated according to his/her disease subtype.

These are intended to control or eradicate disease vectors and pests, or to spread useful traits through wild populations for disease control or conservation purposes. However, a crucial problem for gene drives is the evolution of resistance against them, preventing their spread. Understanding the mechanisms by which populations might evolve resistance is essential for engineering effective gene drive systems. This review summarizes our current knowledge of drive resistance in both natural and synthetic gene drives. We explore how insights from naturally occurring and synthetic drive systems can be integrated to improve the design of gene drives, better predict the outcome of releases and understand genomic conflict in general.This study reports the outcomes of a systematic literature review, which aims to determine the influence of four indoor environmental parameters - indoor air, thermal, acoustic, and lighting conditions -on the quality of teaching and learning and on students' academic achievement in schools for higher education, defined as education at a college or university. By applying the Cochrane Collaboration Method, relevant scientific evidence was identified by systematically searching in multiple databases. After the screening process, 21 publications of high relevance and quality were included. The collected evidence showed that the indoor environmental quality (IEQ) can contribute positively to the quality of learning and short-term academic performance of students. However, the influence of all parameters on the quality of teaching and the long-term academic performance could not be determined yet. Students perform at their best in different IEQ conditions, and these conditions are task-dependent, suggesting that classrooms which provide multiple IEQ classroom conditions facilitate different learning tasks optimally. In addition, the presented evidence illuminates how to examine the influence of the IEQ on users. Finally, this information supports decision-makers in facility management and building systems engineering to improve the IEQ, and by doing so, allow teachers and students to perform optimally.

Damage to enteric neurons and impaired gastrointestinal muscle contractions cause motility disorders in 70% of diabetic patients. It is thought that enteric neuropathy and dysmotility occur before overt diabetes, but triggers of these abnormalities are not fully known. We tested the hypothesis that intestinal contents of mice with and without high-fat diet- (HFD-) induced diabetic conditions contain molecules that impair gastrointestinal movements by damaging neurons and disrupting muscle contractions.

Small and large intestinal segments were collected from healthy, standard chow diet (SCD) fed mice. Filtrates of ileocecal contents (ileocecal supernatants; ICS) from HFD or SCD mice were perfused through them. Cultured intact intestinal muscularis externa preparations were used to determine whether ICS and their fractions obtained by solid-phase extraction (SPE) and SPE subfractions collected by high-performance liquid chromatography (HPLC) disrupt muscle contractions by injuring neurons and smooth muscle cells.
