Epidemiological Characteristics of Falls from the National Injury Surveillance System - China, 2019-2022.

Introduction: This study describes and analyzes the distribution of fall cases documented in the National Injury Surveillance System (NISS) from 2019 to 2022.

Methods: Fall data from the NISS (2019-2022) were descriptively analyzed by gender and age.

Results: The NISS in China reported 2,324,577 fall cases from 2019 to 2022.

Comparative study of trastuzumab modification analysis using mono/multi-epitope affinity technology with LC-QTOF-MS.

Dynamic tracking analysis of monoclonal antibodies (mAbs) biotransformation is crucial, as certain modifications could inactivate the protein and reduce drug efficacy. However, a particular challenge (i.e.

Environmental DNA/RNA metabarcoding for noninvasive and comprehensive monitoring and assessment of marine fishes.

Marine fisheries resources are under increasing threat, necessitating the development of new effective monitoring and management strategies. Environmental DNA (eDNA) and RNA (eRNA) metabarcoding has emerged as a non-invasive and sensitive alternative method for monitoring fish biodiversity and fisheries resources and assessing the fisheries impact of anthropogenic activities. Here, we summarize crucial technical details about eDNA metabarcoding for marine fish monitoring and provide meta-analytical trends in primer selection and sample size, assessment standards, fish and fisheries databases, reference fish genomic databases, and other relevant metrics.

Kerr-lens mode-locked GHz-repetition-rate Yb:CYA laser with 11-W average power.

We demonstrate on a high-power 1-GHz Kerr-lens mode-locked (KLM) ytterbium (Yb):CYA laser delivering 149-fs pulses with an average power of 11.1 W. The corresponding single-pulse energy and peak power are 10.
