Two kinds of carbon dots with the maximum fluorescence peak of 492 nm (named as G-CDs) and 607 nm (named as R-CDs) were synthesized. In the presence of MoO ions, the fluorescence of R-CDs at 607 nm can be quenched, which can probably be assigned to their aggregation caused by MoO, while that of G-CDs at 492 nm remained unchanged. For the first time, a ratiometric fluorescence probe was developed for MoO ions detection.

Mouse model of acute hypoxia was constructed by using a sealed glass jar. Laser speckle contrast imaging was used to detect the changes of cerebral blood flow after different time duration of hypoxia.

Background: Controversy over the issue that No. 12a lymph node involvement is distant or regional metastasis remains, and the possible inclusion of 12a lymph nodes in D2 lymphadenectomy is unclear. As reported, gastric cancer (GC) located in the lower third is highly related to the metastasis of station 12a lymph nodes.

The ideal position for inferior eyelid fat fixation is to cross the tear trough ligament causing tear trough depression and the orbicularis retaining ligament, with the distal end fixed at the farthest end of the dissected lacuna deep down the inferior orbicularis oculi muscle. Traditional suturing is difficult in the deep narrow lacunae, but a buried guide needle can be used to suture and fix the fat in the deepest lacuna.

Inappropriate use of neoadjuvant therapy, however, may lead to the loss of therapeutic opportunities. Until an effective prediction model of individual drug sensitivity is established, no accurate model exists to help surgeons decide on the appropriate use of neoadjuvant chemotherapy.

Alkaline phosphatase (ALP) is an important biomarker for diagnosis, and the abnormal level of serum ALP is closely related to a variety of diseases. In present work, a ratiometric fluorescence probe based on hybrid nanoparticles CDs@YVO: Dy nanoparticle is introduced for alkaline phosphatase (ALP) activity determination. The CDs@YVO: Dy probe is constructed by the carbon dots (CDs) and YVO: Dy through a simple mixing method, in which the blue emission of CDs at 405 nm acts as the calibrated signal, the green emission of YVO: Dy at 574 nm decreased with the increasing targets ALP, and used as the output signal.

Previously, we proposed that Menin acts as a tumor suppressor by inhibiting cell growth in pancreatic ductal adenocarcinoma (PDAC), whereas the relationship between the Menin expression and overall survival rate of PDAC patients has not been completely elucidated, indicating the complexity of Menin functions in PDAC progression. Here, we identify Menin as a promoter of epithelial-mesenchymal transition (EMT), which is largely associated with cell migration or metastasis, with modest activity in cell growth inhibition.

In the conjugates, the 24-COOH of the bile acids was kept intact to preserve liver-specific recognition. The ability of the newly synthesized conjugates (at 100 mg/kg dosage) to reduce total cholesterol (TC) and triglyceride (TG) levels in mice fed with high-fat diet (HFD) was evaluated.

Currently, there has been no approved drug to treat NAFLD or NASH. The current study has presented RLA8, a novel and balanced quadruple agonist for hepatic lipid metabolism and inflammation-related peroxisome proliferator-activated receptors (PPARs)-// and G protein-coupled receptor 40 (GPR40), as a NASH drug candidate.
