Article Synopsis
  • There's a rising demand for effective sensors to detect toluene due to concerns about environmental and personal health.
  • Metal oxide semiconductor (MOS) sensors are popular for this purpose but face issues with selectivity, temperature, and stability, limiting their practical use.
  • The recently developed AuPt@ZnO nanoflower sensors show a significant improvement in performance, with enhanced sensitivity, lower operating temperature, and better stability, making them promising for real-world toluene detection.

The mature processes of metal oxide semiconductors (MOS) have attracted considerable interest. However, the low sensitivity of metal oxide semiconductor gas sensors is still challenging, and constrains its practical applications. Bimetallic nanoparticles are of interest owing to their excellent catalytic properties.

Three-dimensional NAND flash memory is widely used in sensor systems as an advanced storage medium that ensures system stability through fast data access. However, in flash memory, as the number of cell bits increases and the process pitch keeps scaling, the data disturbance becomes more serious, especially for neighbor wordline interference (NWI), which leads to a deterioration of data storage reliability. Thus, a physical device model was constructed to investigate the NWI mechanism and evaluate critical device factors for this long-standing and intractable problem.

Objective: To investigate the effect of Da-Cheng-Qi decoction (DCQD) on treating intestinal injury in rats with severe acute pancreatitis (SAP), based on the Janus kinase 2 (JAK2)/signal transducers and transcription 3 (STAT3) signaling pathway.

Methods: Rats were randomly divided into the SAP group, SAP + ruxolitinib (JAK2 inhibitor) group, SAP + Stattic (STAT3 inhibitor) group, SAP + DCQD group, and sham operation group. They were further divided into 3-hour, 6-hour, 12-hour, and 18-hour subgroups.

Purpose: Pancreatoduodenectomy is the most common operative procedure performed for distal bile duct carcinoma. Data on outcome after surgery for this rare malignancy is scarce, especially from western countries. The purpose of this study is to explore the prognostic factors and outcome after pancreatoduodenectomy for distal bile duct carcinoma.

Purpose: To assess the available evidence on the prognostic factors for the 5-year survival for patients with distal cholangiocarcinoma (DCC) following surgical resection.

Methods: We performed a comprehensive search of abstracts included in databases where relevant studies were published between January 2000 and August 2015. Risk ratios (RRs), 95 % confidence intervals (95 % CIs), and random-effects model were calculated using RevMan 5.

Purpose: To investigate the relationship between the APACHE II score and the immunity of patients with severe acute pancreatitis.

Methods: Clinical data were collected from 88 patients with acute pancreatitis, divided into four groups according to the severity of the disease. C-reactive protein (CRP), tumor necrosis factor-α, interleukin-6, interleukin-10, interleukin-4 and endotoxin (ET) in serum were measured on admission and then on days 3, 5, and 7.

Objective: To evaluate the effectiveness of pharmaconutrition-supplemented parenteral nutrition (PN) for severe acute pancreatitis (SAP).

Methods: A comprehensive search of abstracts was performed in the MEDLINE, OVID, Springer, and Cochrane Library database. Published data of randomized clinical trials (RCTs) comparing the clinically relevant outcomes of pharmaconutrition-supplemented PN versus PN for patients with SAP were analyzed.

Purpose: The aim of our study was to evaluate the safety and effectiveness of early enteral nutrition (EN) for patients after pancreatoduodenectomy (PD).

Methods: We performed a comprehensive search of abstracts in the MEDLINE database, OVID database, Springer database, the Science Citation Index, and the Cochrane Library database. Published data of randomized clinical trials (RCTs) comparing the clinically relevant outcomes of early EN and other nutritional routes for patients after PD were analyzed.

The aim of our study was to observe the dynamic changes of immunity for patients with severe acute pancreatitis (SAP) and intervention by traditional Chinese medicine. Twenty-three patients who met the inclusion criteria were randomized to combined treatment of traditional Chinese medicine and Western medicine (TCM) or conventional western medicine treatment (WM) groups. The clinical data for all patients were collected.

To investigate patients with severe acute pancreatitis (SAP) by dynamic levels of pro-/anti-inflammatory cytokines and endotoxin (ET) in plasma and the relationship between immunity and infection, organ dysfunction. Seventy-two patients with SAP were recruited. The ET, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-10 (IL-10), and interleukin-4 (IL-4) were determined on admission and days 3, 7, and 14.
