Fluoride-incorporated cobalt-based electrocatalyst towards enhanced hydrogen evolution reaction.

We report an electrocatalyst, Co bases (metallic Co and Co(OH)) with fluoride-incorporated CoO coating on the surface of (CoO-F/Co), was synthesized by the electro-deposition method. The porous network architecture of CoO-F/Co on the glassy carbon electrode exhibited an ultra-low overpotential of 15 mV, achieving the geometric current density of 10 mA cm in 1.0 M KOH, which were comparable with the HER performance of numerous reported noble metal electrocatalysts.

Dinitrosyliron Complex [(PMDTA)Fe(NO)]: Intermediate for Nitric Oxide Monooxygenation Activity in Nonheme Iron Complex.

Despite a comprehensive study on the biosynthesis and function of nitric oxide, biological metabolism of nitric oxide, especially when its concentration exceeds the cytotoxic level, remains elusive. Oxidation of nitric oxide by O in aqueous solution has been known to yield NO. On the other hand, a biomimetic study on the metal-mediated conversion of NO to NO/NO via O reactivity disclosed a conceivable pathway for aerobic metabolism of NO.

Intrabullous Adhesion Pexia (IBAP) by Percutaneous Pulmonary Bulla Centesis: An Alternative for the Surgical Treatment of Giant Pulmonary Bulla (GPB).

Background And Objective: Most patients with giant pulmonary bulla (GPB) are treated by surgery; however, there is a subset for whom surgery is not a viable option, such as those with contraindications, or those unwilling to undergo operation. Therefore, an alternative minimally invasive method is desired for this subpopulation. The aim of this study was to explore an alternative procedure for treating GPB.

Electrodeposited-film electrodes derived from a precursor dinitrosyl iron complex for electrocatalytic water splitting.

In artificial photosynthesis, water splitting plays an important role for the conversion and storage of renewable energy sources. Here, we report a study on the electrocatalytic properties of the electrodeposited-film electrodes derived from irreversible electro-reduction/-oxidation of a molecular dinitrosyl iron complex (DNIC) {Fe(NO)2}9 [(Me6tren)Fe(NO)2]+ (Me6tren = tris[2-(dimethylamino)ethyl]amine) for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in alkaline solution, individually. For HER, the overpotential and Tafel slope for the electrodeposited-film cathode are lower than those of the equiv.

Peritoneum as the sole distant metastatic site of lung adenosquamous cell carcinoma: a case report.

Background: Peritoneum metastasis of lung cancer is a rare event which, in addition to the peritoneum, usually involves multiple metastatic tissues. Here we report a case of a patient with lung adenosquamous cell carcinoma with the peritoneum as the sole distant metastatic site.

Case Presentation: An 82-year-old Han Chinese man, in the teaching profession, was diagnosed with lung adenosquamous cell carcinoma in the upper lobe of his left lung with the involvement of ipsilateral hilar and mediastinal lymph nodes, and was initially staged as IIIa (cTNM).

Combination of acoustic radiation force impulse imaging, serological indexes and contrast-enhanced ultrasound for diagnosis of liver lesions.

Aim: To assess the value of combined acoustic radiation force impulse (ARFI) imaging, serological indexes and contrast-enhanced ultrasound (CEUS) in distinguishing between benign and malignant liver lesions.

Methods: Patients with liver lesions treated at our hospital were included in this study. The lesions were divided into either a malignant tumor group or a benign tumor group according to pathological or radiological findings.

Effects of berberine on pharmacokinetics of midazolam and rhodamine 123 in rats in vivo.

Aim: To evaluate whether berberine hydrochloride (BBR) could modify the pharmacokinetic profiles of midazolam (MDZ), a substrate of CYP3A, and rhodamine 123 (Rh123), a substrate of P-glycolprotein (P-gp), in male rats.

Methods: The rats were given with varied does of BBR or 75 mg/kg ketoconazole as a positive control for 10 days by intragastric administration. Single-pass duodenum perfusion of 20 mg/kg MDZ and inguinal artery canulated rats were used in the study.

Blind source separation based x-ray image denoising from an image sequence.

Blind source separation (BSS) based x-ray image denoising from an image sequence is proposed. Without priori knowledge, the useful image signal can be separated from an x-ray image sequence, for original images are supposed as different combinations of stable image signal and random image noise. The BSS algorithms such as fixed-point independent component analysis and second-order statistics singular value decomposition are used and compared with multi-frame averaging which is a common algorithm for improving image's signal-to-noise ratio (SNR).

Liver reserve function assessment by acoustic radiation force impulse imaging.

Aim: To evaluate the utility of liver reserve function by acoustic radiation force impulse (ARFI) imaging in patients with liver tumors.

Methods: Seventy-six patients with liver tumors were enrolled in this study. Serum biochemical indexes, such as aminotransferase (ALT), aspartate aminotransferase (AST), serum albumin (ALB), total bilirubin (T-Bil), and other indicators were observed.

In vivo effect of Schisandrin B on cytochrome P450 enzyme activity.

To investigate the possible drug interaction, this study is designed to evaluate the ability of Schisandrin B (Sch B) to modulate cytochrome P450 3A activity (CYP3A) in vivo and to alter the pharmacokinetic profiles of CYP3A substrate (midazolam) in treated rats. Rats were repeated administered with physiological saline (negative control group), ketoconazole (75 mg/kg, positive control group) or varied doses of Sch B (experimental groups) for three consecutive days. Subsequently, changes in hepatic microsomal CYP3A activity and the pharmacokinetic profiles of midazolam and 1'-hydroxy midazolam in plasma were studied to evaluate CYP3A activity.

Inhibitory effects of continuous ingestion of Schisandrin A on CYP3A in the rat.

The objective of this study was to evaluate the ability of schisandrin A (SchA) to inhibit the P450 enzyme CYP3A in vivo. Male Sprague-Dawley rats were intragastrically administered with varied doses of SchA (8 mg/kg or 16 mg/kg or 32 mg/kg) or 75 mg/kg ketoconazole for three consecutive days. Ketoconazole, a chemical inhibitor of CYP3A, was used as positive control.

[Effect of co-inhibition of MCT1 gene and NHE1 gene on proliferation and growth of human lung adenocarcinoma cells].

Background & Objective: The authors previously discovered that the intracellular pH values (pHi) of tumor cells could be decreased, which led tumor cells to acidify and die, when the expressions of the first subtype of monocarboxylate transporter (MCT1) gene and the first subtype of Na+/H+ exchanger (NHE1) gene in tumor cell membranes had been inhibited by each corresponding antisense gene respectively. However it was not clear whether there were co-effects on the pHi, proliferation, and growth of tumor cells, after two genes were inhibited at the same time.

Methods: pLXSN-MCT1 and pLXSN-NHE1, the corresponding antisense gene expression vectors of MCT1 and NHE1 genes, were introduced into human lung adenocarcinoma A549 cells at the same time with electroporation.
