Trajectories of breast density change over time and subsequent breast cancer risk: longitudinal study.

Objective: To identify clusters of women with similar trajectories of breast density change over four longitudinal assessments and to examine the association between these trajectories and the subsequent risk of breast cancer.

Design: Retrospective cohort study.

Setting: Data from the national breast cancer screening programme, which is embedded in the National Health Insurance Service database in Korea.

Synthesis and Physico-Chemical Analysis of Dextran from Maltodextrin via pH Controlled Fermentation by .

Dextran is an exopolysaccharide (EPS) with multifunctional applications in the food and pharmaceutical industries, primarily synthesized from . Dextran can be produced from dextrin through fermentation, utilizing its dextran dextrinase activity. This study examined how jar fermentor conditions impact the growth and enzyme activity of , with a focus on the effects of pH on dextran synthesis via bioconversion (without pH control, pH 4.

Tailoring Red-to-Blue Emission in InGaP/ZnSe/ZnS Quantum Dots Using a Novel [In(btsa)Cl] Precursor and GaI.

Ternary InGaP quantum dots (QDs) have emerged as promising materials for efficient blue emission, owing to their tunable bandgap, high stability, and superior optoelectronic properties. However, most reported methods for Ga incorporation into the InP structure have predominantly relied on cation exchange in pre-grown InP QDs at elevated temperatures above 280 °C. This is largely due to the fact that, when heating In and P precursors in the presence of Ga, an InP/GaP core-shell structure readily forms.

A scientific-article key-insight extraction system based on multi-actor of fine-tuned open-source large language models.

The exponential growth of scientific articles has presented challenges in information organization and extraction. Automation is urgently needed to streamline literature reviews and enhance insight extraction. We explore the potential of Large Language Models (LLMs) in key-insights extraction from scientific articles, including OpenAI's GPT-4.

Acetogenesis to ethanologenesis: facilitating NADH oxidation via reductive acetate uptake.

(Homo)acetogens, including Clostridium spp., represent an enigma in metabolic flexibility and diversity. Eubacterium callanderi KIST612 is an acetogen that produces n-butyrate with carbon monoxide (CO) as the carbon and energy source; however, the production route is unknown.
