Estimating cumulative infection rate of COVID-19 after adjusting the dynamic zero-COVID policy in China.

Background: At the end of 2022, China adjusted its coronavirus disease 2019 (COVID-19) prevention and control strategy. How this adjustment affected the cumulative infection rate is debated, and how second booster dose vaccination affected the pandemic remains unclear.

Methods: We collected COVID-19 case data for China's mainland from December 7, 2022, to January 7, 2023, reported by the World Health Organization.

Synthetic microbial community enhances lignocellulose degradation during composting by assembling fungal communities.

Inoculating synthetic microbial community (SynCom) has been proposed as an eco-friendly approach for lignocellulose degradation in composting to enhance organic fertilizer quality. However, the mechanisms responsible for SynCom-regulated lignocellulose degradation during composting remain unclear. Here the SynCom inoculation decreased cellulose and hemicellulose contents by 26.

Comparison of anterior and posterior approaches for the treatment of cervical ossification of the posterior longitudinal ligament: a meta-analysis of 28 cohort studies.

At present, the choice of approach for the surgical treatment of cervical ossification of the posterior longitudinal ligament (OPLL) remains controversial. We performed this meta-analysis to compare the efficacy of the anterior and posterior approaches in the treatment of cervical OPLL. PubMed, EMBASE and the Cochrane Library were systematically searched for all eligible articles as of August 3, 2023, without any publication date restrictions.

Simultaneous Detection of Hydrogen Sulfide and Peroxynitrite Dysregulation with a Sequentially Activated Fluorescent Probe in Ulcerative Colitis Disease.

Ulcerative colitis (UC), often referred to as "green cancer", is a chronic inflammatory bowel disease with an unclear etiology, closely associated with the imbalance of hydrogen sulfide (HS) and peroxynitrite (ONOO). HS exhibits anti-inflammatory effects at physiological levels, but excessive concentrations can compromise the intestinal barrier, while ONOO aggravates inflammation. To facilitate the molecular-level monitoring of these compounds in UC, we developed a novel fluorescent probe, , capable of simultaneously detecting HS and ONOO via distinct fluorescent channels in a cascade mode.

White light-emitting electrochemical cells based on metal-free TADF emitters.

The attainment of white emission from a light-emitting electrochemical cell (LEC) is important, since it enables illumination and facile color conversion from devices that can be cost-efficient and sustainable. However, a drawback with current white LECs is that they either employ non-sustainable metals as an emitter constituent or are intrinsically efficiency limited by that the emitter only converts singlet excitons to photons. Organic compounds that emit by thermally activated delayed fluorescence (TADF) can address these issues since they can harvest all excitons for light emission while being metal free.
