Toxicological Evaluation of the Undesirable Components in Processed Infant Foods Using Artificial Intelligence

open access: yesFuture Postharvest and Food, EarlyView.
The detection of toxins in baby food using artificial intelligence. ABSTRACT Infant foods and baby formulas are becoming increasingly popular across the globe owing to their ease of consumption and nutritional value specific to infants. Impurities may find their way into the food chain at any point from the acquisition of raw materials to final ...

Detection of OH Maser Emission in the 71 yr Periodic Comet 12P/Pons-Brooks Using the 40 m Thai National Radio Telescope

open access: yesThe Planetary Science Journal
Although the optical cometary database is extensive, the radio database is limited. The 18 cm OH maser observations of comets allow us to determine (i) the production rate of OH ( Q _OH ) and (ii) the water expansion velocity, for each comet.

Deubiquitinase USP38 Stabilizes PLK1 Expression to Boost DNA Damage Repair in Ovarian Cancer

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Ovarian cancer (OC) is one of the most prevalent and severe gynecological malignant tumors. DNA damage repair (DDR) is essential in maintaining genome stability. This study aims to investigate the effects and mechanisms of USP38 and PLK1 on DNA damage repair and malignant behavior in OC cells.
