A dataset of Antarctic ecosystems in ice-free lands: classification, descriptions, and maps.

Antarctica, Earth's least understood and most remote continent, is threatened by human disturbances and climate-related changes, underscoring the imperative for biodiversity inventories to inform conservation. Antarctic ecosystems support unique species and genetic diversity, deliver essential ecosystem services and contribute to planetary stability. We present Antarctica's first comprehensive ecosystem classification and map of ice-free lands, which host most of the continent's biodiversity.

The moderating role of social media motives in the relationship between screen usage and cybervictimization.

Background: Screen time is on the rise among youth, and as a result, cyberbullying victimization has become increasingly prevalent. While prior research has established a positive correlation between screen usage and cyberbullying victimization, a paucity of research has explored how motives for screen usage are associated with cyberbullying victimization and moderate the positive association between screen usage and cyberbullying victimization.

Objective: The present study sought to address these research gaps by exploring the association between motives for screen usage and cyberbullying victimization and examining whether these motives moderate the association between screen time and cyberbullying.

Homogeneous and bioluminescent biochemical and cellular assay for monitoring cGAMP and enzymes that generate and degrade cGAMP.

The cyclic GMP-AMP synthase-stimulator of the interferon gene (cGAS-STING) signaling pathway is considered an essential pattern recognition and effector pathway in the natural immune system and is mainly responsible for recognizing DNA molecules present in the cytoplasm and activating downstream signaling pathways to generate type I interferons (IFN-I) and other inflammatory factors. STING, a crucial junction protein in the innate immune system, exerts an essential role in host resistance to external pathogen invasion. The DNA introduced by pathogens or tumors is recognized by the cytoplasmic nucleic acid receptor cGAS, and a second messenger, cGAMP, is generated using intracellular guanosine triphosphate (GTP) and adenosine triphosphate (ATP).

Specialized Infrared Camera-Computer System (SPY) Imaging for Monitoring the Restoration of Nipple Sensation in Patients Undergoing Breast Reduction.

Introduction Symptomatic mammary hypertrophy (SMH) refers to excessive breast weight exceeding 3% of total body weight, impacting not only the breast but also the nipples and areola. Breast reduction surgery (BRS) has a complication that adversely affects the nipple-areolar complex (NAC) sensation. The purpose of this study was to estimate the degree to which the specialized infrared camera-computer system (SPY) may predict postoperative sensation of the NAC following BRS.

Impact factors and publication times of original scientific research in radiology journals.

Purpose: The time from article submission to publication in peer-reviewed scientific journals is variable and can be prolonged, which slows the dissemination of research and can influence the academic progress of authors. This study evaluated the publication times for articles in radiology journals, in particular the relationship between turnaround times and journal impact factors (IFs).

Methods: Bibliometric data was obtained from Journal Citation Reports to conduct a comparative analysis of radiology journals against those in other disciplines of clinical medicine using highest IF, median IF, cited half-life, immediacy index, and number of journals.
