Abstract. A series of model sensitivity experiments was designed to explore the effects different initial conditions and emissions in Xi'an December 2016; is a major city Fenwei Plain, which key area with respect air pollution control China. Three methods were applied for condition tests: clean simulation, restart continuous simulation. In simulation test, C00, C06, C12, C18, C24 conducted effe...

Raman spectroscopy is promising in vivo tool various biomedical applications; moreover, recent years, its use for characterizing articular cartilage degeneration has been developing. It also shown potential scoring the severity of lesions, which could be useful determining optimal treatment strategy during repair surgery. However, effect different injury types on spectra unknown. This study aim...

Thrombin activates platelets mainly through protease-activated receptor (PAR)1 and PAR4. However, downstream platelet signaling between PAR1 and PAR4 is not yet well understood. This study investigated the relationship between nSMase/ceramide and the NF-κB signaling pathway in PARs-mediated human platelet activation. The LC-MS/MS, aggregometry, flow cytometry, immunoprecipitation, and mesenteri...

Sample selection models are important for correcting for the effects of nonrandom sampling in microeconomic data. This note is about semiparametric estimation using a series approximation to the selection correction term. Regression spline and power series approximations are considered. Consistency and asymptotic normality are shown, as well as consistency of an asymptotic variance estimator. J...

Rat surfactant protein (SP) C is synthesized as a 194-amino acid proprotein that is proteolytically processed to a 35-amino acid mature form in subcellular compartments distal to the medial Golgi compartment. To identify domains of SP-C proprotein (proSP-C) necessary for endoplasmic reticulum translocation and for targeting to cytosolic processing compartments, we characterized expression patte...

BACKGROUND Coronary artery disease (CAD) is associated with verbal memory decline, although deterioration may be mitigated in individuals undertaking exercise interventions. Ceramide sphingolipids, suggested to play a role in pathological neurodegeneration, have been associated with the development and progression of CAD but their relationship with cognitive response to exercise has not been as...

Polyynes are alternations of single and triple bonds between carbon atoms, while cumulenes successions double bonds. Since the bond is strongest two recent preoccupations included synthesizing condensing cyclic polyynes their clusters. Density functional theory calculations predicted stable monocyclic rings formation for a number C atoms equal to or higher than 16. Alternative series Carbon Bor...
