Normal maize germplasm could be used to improve the grain yield of popcorn inbreds. Our first objective was to locate genetic factors associated with trait variation and make first assessment on the efficiency of advanced backcross quantitative trait locus (AB-QTL) analysis for the identification and transfer of favorable QTL alleles for grain yield(More)
AIMS Postsynaptic density (PSD)-95 is a scaffolding protein linking the N-methyl-D-aspartate receptor with neuronal nitric oxide synthase (nNOS), which contributes to many physiological and pathological actions. We here investigated whether PSD-95 was involved in the secondary response following spinal cord injury (SCI). METHODS Spinal cord contusion(More)
Findings on the risk of bone fractures associated with long-term fluoride exposure from drinking water have been contradictory. The purpose of this study was to determine the prevalence of bone fracture, including hip fracture, in six Chinese populations with water fluoride concentrations ranging from 0.25 to 7.97 parts per million (ppm). A total of 8266(More)
We report a study of the application of delayed extraction (DE) to infrared-wavelength matrix-assisted time-of-flight mass spectrometry (IR-MALDI-TOF-MS) of proteins. The shapes of the spectral peaks obtained with DE-IR-MALDI-MS are compared with those obtained from the same samples and matrix using continuous extraction (CE) IR-MALDI-MS. Application of DE(More)
In an effort to gain an understanding of the processes governing matrix-assisted laser desorption/ionization (MALDI), we made a direct comparison of ultraviolet (UV)- and infrared (IR)-MALDI linear time-of-flight mass spectra of proteins obtained from the same samples and matrices (on the same sample surface), using two different lasers, each having short(More)
OBJECTIVE To investigate the diagnostic significance of total respiratory impedance for chronic obstructive lung disease. METHODS The impedance of respiratory system was measured by impulse oscillometry method and compared with parameter values of routine pulmonary function in 57 patients with chronic obstructive pulmonary disease (COPD). RESULTS It(More)
Forsythia suspensa extract (FSE) has been demonstrated to attenuate physiological stress induced by high temperature or high stocking density. This experiment was conducted with 144 male Arbor Acre broilers (1-d-old, weighing 42.7 ± 1.7 g) to determine the effects of FSE on performance, nutrient digestibility, antioxidant activities, serum metabolites, and(More)
OBJECTIVE To study the effects of bone marrow mesenchymal stem cells (MSC) on pulmonary fibrosis. METHODS Bone marrow MSC were harvested from 6 week old male SD rats. Forty-eight female SD rats were randomly divided into six groups. The pulmonary fibrosis models were made by intratracheal instillation of bleomycin (5 mg/kg in 0.3 ml normal saline). The(More)
AIM Rutin, also known as violaguercitrin, is a bioflavonoid and has a wide range of biological activity. However, the effect of this compound on arteries is not elucidated. Therefore, the objective of this study was to investigate the mechanism underling the induction of vasodilation in pulmonary artery (PA) by the natural product, rutin. METHODS Firstly,(More)
PURPOSE To investigate iterative reconstruction via prior image constrained total generalized variation (PICTGV) for spectral computed tomography (CT) using fewer projections while achieving greater image quality. METHODS The proposed PICTGV method is formulated as an optimization problem, which balances the data fidelity and prior image constrained total(More)
