Electrical Kinetic Model of a Hydroxylated Graphene FET Gas Sensor.

Graphene transistor sensors, with advantages such as facile surface functionalization and high sensitivity, have gained extensive research interest in gas detection applications. This study fabricated back-gated graphene transistors and employed a hydroxylation scheme for the surface functionalization of graphene. On the basis of the interaction mechanisms between gas molecules and graphene's electrical properties, a compact electrical kinetics model considering the gas-solid surface reaction of graphene transistors is proposed.

Overexpression of cytoplasmic poly(A)-binding protein 1 as a biomarker for the prognosis and selection of postoperative regimen in breast cancer.

Purpose: The dysregulation of the cytoplasmic poly(A)-binding protein 1 (PABPC1) is involved in a variety of tumors but little is known about its role in human breast cancer. Therefore, the effect of PABPC1 in the prognosis and regimen selection in breast cancer patients was evaluated.

Methods: A total of 791 cases of invasive breast cancer were included in this study, although only 416 were involved in subsequent analyses after the propensity score matching (PSM) test.

Revascularization-first strategy versus central repair-first strategy for acute type A aortic dissection complicated with mesenteric malperfusion syndrome: A meta-analysis.

Objective: The optimal therapeutic strategy for acute type A aortic dissection (ATAAD) accompanied by mesenteric malperfusion syndrome (mMPS) has not been fully elucidated. The intent of this meta-analysis was to analyze the effectiveness and safety of the revascularization-first strategy among patients with ATAAD complicated with mMPS through comprehensive comparisons with the central repair-first strategy.

Methods: Studies relevant to the comparison of the outcomes of early reperfusion combined with delayed proximal aortic repair and initial central repair in the treatment of ATAAD complicated with mMPS, were systematacially searched using PubMed, Cochrane Library, Web of Science and Embase up to June 30, 2022.

Aromatin D-J: Seven previously undescribed labdane diterpenoids isolated from Blumea aromatica.

Blumea aromatica is a traditional Chinese medicine used for treating various diseases such as rheumatoid arthritis, eczema, and pruritus. Previous studies on B. aromatica used a mass defect-filtering strategy via the ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry and reported the presence of several labdane diterpenoids (LADs).

High-Temperature-Annealed Flexible Carbon Nanotube Network Transistors for High-Frequency Wearable Wireless Electronics.

Semiconducting single-walled carbon nanotubes (SWNTs) are potential active materials for fast-growing flexible/wearable applications with low-power dissipation, especially suitable for increasingly important radio-frequency (RF) wireless biosensor systems. However, the operation frequency of the existing flexible carbon nanotube field-effect transistors (CNT-FETs) is far below the current state-of-the-art GSM spectrum frequency band (typical 850 MHz) for near-field wireless communication applications. In this paper, we successfully conduct a 900 °C annealing process for the flexible CNT-FETs and hence significantly improve their operation frequency up to 2.

[Effects of Niaoduqing granule on urine metabolic profile in chronic renal failure rats].

Objective: To investigate the effects of Niaoduqing granule on the urine metabolic profile in chronic renal failure (CRF) rats.

Methods: Thirty six male SD rats were divided into the normal control group, the model group, and the Niaoduqing group with 12 rats in each group. The CRF was induced by gavage of 250 mg·kg·d adenine for 21 d.

The reuse of waste glass for enhancement of heavy metals immobilization during the introduction of galvanized sludge in brick manufacturing.

The mixing of galvanized sludge in fired clay brick manufacturing has been regarded as an alternative approach for the consumption of galvanized sludge. Decreasing the surface area and porosity of fired brick definitely lowers the risk of heavy metal release. In this study, a novel method is proposed to reduce the surface area and porosity of bricks and promote heavy metal immobilization by adding waste glass.

Structural characterization and immunomodulating activities of a novel polysaccharide from Nervilia fordii.

Nervilia fordii (Hance) Schltr. has been widely used as a medicinal and edible herb in Southwest China and Southeast Asia. In this study, NFP-1, a new water-soluble polysaccharidewith a purity of 97.

Evaluation of a 12-week targeted vitamin D supplementation regimen in patients with active inflammatory bowel disease.

Background & Aims: Vitamin D at serum 25(OH)D concentrations above 100 nmol/L is associated with disease remission in patients with IBD, suggesting targeted dosing might be anti-inflammatory. This study aimed to assess the effectiveness, safety and predictors of a 12-week regimen of vitamin D supplementation to achieve such a target in patients with active disease.

Methods: In a pilot study, patients with active colitis and a serum 25(OH)D concentration <75 nmol/L were prescribed oral liquid vitamin D supplementation over 12 weeks using a specific protocol with dose adjusted 4-weekly to aim for a target level of 100-125 nmol/L.
