Surgery for choledochal cysts (CDC) in children younger than 6 months is relatively rare. We report our experience and compare the results between Da Vinci robot-assisted hepaticojejunostomy (RAHJ) and laparoscopic-assisted hepaticojejunostomy (LAHJ) in children younger than 6 months to treat CDC. A retrospective study was conducted on all children under 6 months of age who underwent RAHJ or LAHJ at the Children's Hospital, Zhejiang University School of Medicine, from July 2018 to November 2023.

Thirty-two healthy adult SPF male SD rats, 8 ~ 10 weeks old, weight 240 ~ 260 g, were divided into four groups by the method of random number table (n = 8): sham group, I/R group, I/R + Fer-1 group, I/R + DFO group. In the I/R + Fer-1 group, ferristatin-1(5 mg /kg) was intraperitoneally injected 30 min before surgery; in the I/R + DFO group, DFO 100 mg/kg was injected intraperitoneally 1 h before operation and 12 h after operation.

The widely used Radix Astragali (RA) has significant therapeutic effects on cognitive impairment (CI) caused by type 2 diabetes (T2DM). However, the effective active ingredients and the precise mechanism underly RA alleviation of T2DM-induced CI still require further study. In this study, we aim to elucidate whether and how jaranol, a key effective active ingredient in RA, influences CI in db/db mice.

In this study, the ion ratio, multivariate statistics, and inverse geochemical modeling were used to investigate and explore the chemical characteristics of groundwater and factors driving the formation of groundwater components in the plain area of Deyang City, China. The chemical type of groundwater in the area was dominated by the HCO-Ca type, and the variation in groundwater chemical composition was mainly affected by water-rock interaction and human interference.

On the basis of the calculated activation energy (E) and reaction energy (E), the optimal energy path for the hydrogenation of HMF (F-CHO) into BHMF (F-CHOH) on Pd(111) is as follows: F-CHO + 2H → F-CHOH + H → F-CHOH; the minimum reaction path on Cu(111) is F-CHO + 2H → F-CHO + H → F-CHOH. On Cu(111), the formation of F-CHOH from F-CHO hydrogenation is the rate-determining step because it has the highest reaction energy barrier and the smallest rate constant.

Herein, a selenium (Se) sacrificial layer is introduced between the rhenium sulfide (ReS) semiconductor and source/drain electrode. With the Se layer and postannealing process, the ReS transistor significantly decreases the off-state current with a substantial increase in the on-state current density.

Lodging reduces grain yield and quality in cereal crops. Lodging resistance is affected by the strength of the culm, which is influenced by the culm diameter, culm wall thickness, and cell wall composition. To explore the genetic architecture of culm diameter in rice (Oryza sativa), we conducted a genome-wide association study (GWAS).

Hydrogen peroxide, phenols, amines, aldehydes, and other substances can easily damage intracellular biomacromolecules. Although natural peroxidases can convert these harmful substances into benign ones, the high costs, poor stabilities, and stringent application conditions associated with these enzymes necessitate the exploration of artificial mimics. In this study, Ce-doped MIL-101(Fe)-NH and MIL-101(Fe)-NO were synthesized with varying compositions a solvothermal method.

While previous studies suggest that mechanical forces may enhance exosome release, the direct relationship between these forces and exosome secretion needs to be further characterized. Here, we utilized dual-color CD63 reporter-based high-speed live-cell imaging to visualize how mechanical forces influence exosome release in situ.

Due to the low response rate and low PD-L1 expression in pancreatic cancer, the therapeutic application of PL-L1 inhibitors in pancreatic cancer is greatly limited. In vitro studies showed that the expression of PD-L1 increased in pancreatic cancer cells stimulated by fluorouracil (5-FU).

In a mixed alkali activation system, the role of each individual alkali has generally been assumed to be the same as in a single alkali activation system, and the low corrosiveness of weak alkalis has mainly been emphasized. However, the intrinsic roles of the individual alkalis should be understood in detail and redefined to illuminate the activation pathways from the perspective of internal chemical reactions rather than corrosiveness.

The selenium-containing crown ether macrocycle, featuring a strong hydrophilic hydrogen-bond receptor (selenoxide) and a synergistic hydrophobic selenium-substituted crown core, confines water within a segregated, interdigitated architecture. While water molecules typically freeze around 0 °C, the confined water in this supramolecular polymer remains in a liquid-like state down to -80 °C.

Herein, a magnetic field (MF) induced combination of chemo/photothermal therapy is demonstrated using FeO@mSiO@Au core@shell@satellites nanoparticles (NPs) loaded with chemotherapeutic drug doxorubicin (DOX), both and An application of an external MF to the NPs dispersion causes magnetophoretic movement and aggregation of the NPs. While the synthesized NPs only slightly absorb light at ∼800 nm, their aggregation results in a significant near infrared (NIR) absorption associated with plasmon resonance coupling between the Au satellites in the NPs aggregates.
