Flowering is initiated in response to environmental cues, with the photoperiod and ambient temperature being the main ones. The regulatory pathways underlying floral transition are well studied in but remain largely unknown in legumes. Here, we first applied an in silico approach to infer the regulatory inputs of four -like genes of the narrow-leafed lupin .

Coenzyme Q (CoQ), a component of the electron transport chain, participates in aerobic respiration to produce ATP. Little is known about the relationship between CoQ and ethanol fermentation. Herein, we revealed that the deficiency or the addition of CoQ in sake yeast led to an increase or a decrease, respectively, in ethanol production rate at the early stage of fermentation.

Magnetic nanoparticles modified with tetraethyl orthosilicate (FeO@TEOS) and bovine serum albumin (FeO@TEOS@BSA) were evaluated as sorbent in albumin depletion from human serum samples by magnetic dispersive solid phase extraction. Characterization studies were carried out by X-ray diffraction, thermogravimetry, Fourier transform infrared spectroscopy, zeta potential, and scanning electron microscopy. Both nanoparticles also showed high thermal stability and pH-dependent surface charges.

Article Synopsis
  • - Detection and diagnosis of colon polyps are crucial for preventing colorectal cancer, and AI technologies can improve colonoscopy effectiveness through computer-aided detection (CADe) and diagnosis (CADx) systems.
  • - The REAL-Colon dataset offers a large collection of 2.7 million native video frames from real-world colonoscopy, featuring 350,000 expert-annotated bounding boxes, which provide a more realistic dataset compared to existing down-sampled images.
  • - This dataset includes comprehensive patient and procedural data, promoting transparency and enabling researchers to develop and benchmark more accurate AI algorithms for improved colonoscopy outcomes.

Perivascular epithelioid cell tumor (PEComa) is a rare mesenchymal tumor. Some papers have reported that colonoscopy could be used to treat PEComa with a predominantly pedunculated polyp, whereas surgical intervention is often required for cases with submucosal-type tumors. These findings suggest that the morphology of PEComa changes dramatically with disease progression.
