Background: Non-small cell lung carcinoma (NSCLC) is one of the most common human cancers, comprising approximately 80-85% of all lung carcinomas. An estimated incidence of NSCLC is approximately 2 million new cases per year worldwide.
Results: In recent decade, the treatment of NSCLC has made breakthrough progress owing to a large number of targeted therapies which were approved for clinical use.
The effects of ultrasonic introduced by L-shaped sonotrodes made of high-temperature-resistant ceramic on the microstructure and macro-segregation of solidifying 15t AA2219 aluminum alloy ingots have been examined in the present study. The macroscopic morphology of the corrosion of the sonotrode has been observed. Grain refinement has been observed, the shape and size of the precipitated phase of the ingot were counted, and the degree of segregation along the transverse direction at 500 mm from the head of the ingot has been evaluated.

Neferine has long been recognized as a medicinal herbal ingredient with various physiological and pharmacological activities. Although previous studies have reported its antithrombotic effect, the underlying mechanisms have not been thoroughly investigated. Since platelets play a key role in thrombosis, we investigated the effects of neferine on human platelet function and the potential mechanisms.

L1, a B3 subclass MβL, hydrolyzes almost all of known β-lactam antibiotics. We report a simple and straightforward UV-Vis approach for real-time activity assays of β-lactamases inside living bacterial cells, and this method has been exemplified by choosing antibiotics, L1 enzyme, Escherichia coli expressing L1 (L1 E.

Metallo-β-lactamases (MβLs) such as New Delhi MβL-1 (NDM-1) are principle contributors to the emergence of resistance because of their ability to hydrolyze almost all known β-lactam antibiotics including penicillins, cephalosporins, and carbapenems. A clinical inhibitor of MBLs has not yet been found.

Recent studies have demonstrated that THSG has potent anti-oxidative and anti-inflammatory effects. In this study, we investigated the anti-platelet aggregation, secretion and spreading of THSG with different methods.

Neferine has many biological activities, including anti-hypertensive, anti-arrhythmic, negative inotropic effect and relaxation on vascular smooth muscle. Although previous studies have reported its antithrombotic effect, the mechanisms by which it exerts antithrombotic effect have not been thoroughly studied.

Objective: To study the effects of blocking transforming growth factor beta (TGF-beta) signalling on culture-activated rat hepatic stellate cells (HSCs).
Methods: After cultured in plastic dish for two days, HSCs were infected with adenovirus vector AdT beta-ExR or AdLacZ (control) at 10 multiplicity of infection (MOI) and incubated for four days. The expression of type I collagen, alpha-smooth muscle actin (alpha-SMA) and the proliferation of HSCs were analyzed by ELISA, western blot, immunocytochemistry and BrdU uptake respectively.
