Application of imaging techniques in pancreaticobiliary maljunction.

Imaging techniques are useful tools in the diagnosis and treatment of pancreaticobiliary maljunction (PBM). PBM is a precancerous lesion often relative to the disease of the pancreas and biliary tract, for example, cholecystolithiasis, protein plugs, and pancreatitis. For patients with PBM, early diagnosis and timely treatment are highly important, which is largely dependent on imaging techniques.

Molecular characterization of Clostridioides difficile ribotype 027 in a major Chinese hospital.

Background: The rapid spread of C. difficile 027 has become one of the leading threats of healthcare-associated infections wordwild. However, C.

Genome‑wide profiling of lncRNA expression patterns in patients with acute promyelocytic leukemia with differentiation therapy.

Long non‑coding RNAs (lncRNAs) are crucial factors in acute promyelocytic leukemia (APL) cell differentiation. However, their expression patterns and regulatory functions during all‑trans‑retinoic acid (ATRA)‑induced APL differentiation remain to be fully elucidated. The profile of dysregulated lncRNAs between three bone marrow (BM) samples from patients with APL post‑induction and three BM samples from untreated matched controls was examined with the Human Transcriptome Array 2.

A facile sodium alginate-based approach to improve the mechanical properties of recycled fibers.

The application of recycled fibers is steadily increasing in various paper products recently. It is necessary to improve the mechanical properties of paper products made from these fibers. An eco-friendly polymeric additive, sodium alginate (SA), was prepared from waste seaweeds and developed as functional additives.

[Chemical constituents from root bark of Dictamnus dasycarpus].

Objective: To isolate and identify the chemical constituents from the root bark of Dictamnus dasycarpus.

Methods: Silica gel, Sephadex LH-20, ODS and PTLC were employed for the isolation and purification of chemical constituents. The structures were identified on the basis of spectral data and physicochemical examination.

Structural variation of bamboo lignin before and after ethanol organosolv pretreatment.

In order to make better use of lignocellulosic biomass for the production of renewable fuels and chemicals, it is necessary to disrupt its recalcitrant structure through pretreatment. Specifically, organosolv pretreatment is a feasible method. The main advantage of this method compared to other lignocellulosic pretreatment technologies is the extraction of high-quality lignin for the production of value-added products.

[Targeted delivery of bone marrow mesenchymal stem cells by ultrasound-mediated microbubble destruction].

Objective: To investigate the feasibility of bone marrow mesenchymal stem cell (MSC) transplantation with ultrasound-targeted microbubble destruction.

Methods: Twenty-one Wistar rats were divided into MSCs-iv group (MSCs-iv), ultrasound+MSCs-iv group (US+MSCs-iv), ultrasound+microbubble+MSCs-iv group (US+MB+MSCs-iv) with intravenous MSC transfer, ultrasound and microbubble treatment as indicated. The skeletal muscles were obtained from the rats for microscopic examination with HE staining.
