Coral-Symbiodiniaceae symbiotic associations under antibiotic stress: Accumulation patterns and potential physiological effects in a natural reef.

Antibiotics threaten scleractinian corals, but their accumulation patterns and physiological effects on corals in natural reefs remain unclear. This study investigated antibiotic occurrence in seawater and two coral species, Galaxea fascicularis and Pocillopora damicornis, and explored the physiological effects of bioaccumulated antibiotics in a fringing reef of the South China Sea. Nineteen antibiotic components were detected in seawater, with total antibiotic concentrations (ΣABs) ranging from 17.

Modular cascade with engineered HpaB for efficient synthesis of hydroxytyrosol.

Hydroxytyrosol, a naturally occurring chemical with antioxidant and antiviral properties, is widely used in the nutrition, pharmaceutical, and cosmetic industries. In the present study, a modularized cascade composed of Modules 1 and 2 was designed and implemented to convert l-tyrosine to hydroxytyrosol. Module 1 was a four-enzymatic cascade for converting l-tyrosine to tyrosol.

A new pipeline SPICE identifies novel JUN-IKZF1 composite elements.

Transcription factor partners can cooperatively bind to DNA composite elements to augment gene transcription. Here, we report a novel protein-DNA binding screening pipeline, termed Spacing Preference Identification of Composite Elements (SPICE), that can systematically predict protein binding partners and DNA motif spacing preferences. Using SPICE, we successfully identified known composite elements, such as AP1-IRF composite elements (AICEs) and STAT5 tetramers, and also uncovered several novel binding partners, including JUN-IKZF1 composite elements.

Effect of low-dose radiation pre-irradiation on postoperative local chest wall recurrence of breast cancer-A retrospective study.

Purpose: The purpose of this study was to determine the efficacy and safety of low-dose radiotherapy (LDR) for postoperative local chest wall recurrence of breast cancer.

Methods: The records of 52 patients with postoperative local chest wall recurrent breast cancer treated at our cancer center from January 2019 to December 2022. The t-test was used to compare the means of the LDR group and non LDR group.

Sex Disparities in Cognitive Impairment Research: A Scoping Review in Informatics Literature.

Rationale: A scoping review was conducted to investigate knowledge gaps in the informatics research literature regarding sex differences in cognitive decline, identifying existing studies and areas where further studies are needed.

Materials And Methods: We searched Ovid and other databases for studies on sex differences and cognitive decline, focusing on publications in peer-reviewed informatics journals and conference proceedings from 2000 to 2023. The selected manuscripts were analyzed and summarized through discussion among three reviewers.
