Introduction: Choline participates in plant stress tolerance through glycine betaine (GB) and phospholipid metabolism. As a salt-sensitive turfgrass species, Kentucky bluegrass () is the main turfgrass species in cool-season areas.
Methods: To improve salinity tolerance and investigate the effects of choline on the physiological and lipidomic responses of turfgrass plants under salinity stress conditions, exogenous choline chloride was applied to Kentucky bluegrass exposed to salt stress.
Histamine-gated chloride channels (HACls) mediate fast inhibitory neurotransmission in invertebrate nervous systems and have important roles in light reception, color processing, temperature preference and light-dark cycle. The fall armyworm, Spodoptera frugiperda is a main destructive pest of grain and row crops. However, the pharmacological characterization of HACls in S.

We calculate the adsorption energy, equilibrium distance, Mulliken charge transfer, electron localization function, and work function to explore whether P2C2 is suitable for detecting NO2 gas. The results demonstrate that the P2C2 monolayer is highly sensitive and selective to NO2 gas molecules with robust adsorption energy and superior charge transfer due to the existence of strong orbital hybridization between the NO2 molecule and monolayer P2C2.

Methods: From June 2008 to March 2013, 122 patients (95 men and 27 women; mean age, 50.9 ± 10.
Objective: To explore the feasibility of open single-branched stent graft placement for simplified total arch replacement in acute Stanford type A aortic dissection.
Methods: Between June 2008 and September 2009, 23 patients with acute Stanford type A aortic dissection underwent total arch replacement plus open single-branched stent graft placement. When core nasopharyngeal temperature dropped to 68 H, the perfusion to lower body was discontinued.
Background: In total arch replacement for patients with acute type A aortic dissection, anastomoses of the graft to the left subclavian artery and descending aorta are often difficult, and the arch vessel anastomosis is frequently performed at the site of dissection. To make this procedure easier and safer, we developed 2 modified techniques: open single-branched stent graft placement into the left subclavian artery and the descending aorta and reinforcement of the dissected arch vessel stump with a stent graft neointima. The feasibility and initial clinical results of these 2 new techniques are reported.

We developed a single-branched stent graft that was constructed by adding a side arm stent-graft to a conventional aortic stent graft. By its open placement into the origin of the left subclavian artery and the descending aorta, the left subclavian artery anastomosis could be avoided, and the distal aortic anastomosis was performed at the proximal arch between the brachiocephalic artery and the left common carotid artery.

The potential oncogenic role of CCRK and its clinical/prognostic significance, however, in ovarian carcinoma are unclear. In this study, CCRK expression was examined by immunohistochemistry in a series of ovarian carcinoma tissues.

Objective: To observe the clinic effect of combined use of berberin hydrochloride (Ber) with cyclosporine A (CsA) on the blood concentration of CsA in heart transplanted recipients.
Methods: The blood concentration of CsA, liver-renal function and blood lipids in 22 heart transplanted recipients, who received Ber-CsA combined therapy, were measured.
Results: The whole blood steady state concentration of CsA, C0 and C2, in recipients after being treated with Ber-CsA significantly increased than those before applying Ber-CsA (P < 0.

Objective: To investigate the significance and mechanisms of overexpression of p21-activated kinase 1 gene (PAK1) in epithelial ovarian neoplasms.
Methods: Immunohistochemistry, fluorescence in situ hybridization and terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling methods were used to examine the protein expression and amplification of PAK1 and cell apoptosis in 30 benign ovarian adenomas, 20 borderline tumors and 80 ovarian carcinomas by tissue microarray.
Results: In immunohistochemistry study, overexpression of PAK1 protein was observed in 7 (25.
Objective: To investigate the molecular mechanisms of tauopathies. Comparative proteomic analysis of brain proteins was employed to study 4 patients with tauopathies as compared with 4 controls.
Methods: The brains of subjects who died without clinical or pathological involvement of nervous system and brains of patients with tauopathies were obtained at autopsy.

Objective: To compare the results of proteomics between the cerebellum and frontal lobe of the aged.
Method: Proteins were isolated from human cerebellums and frontal lobes and separated by two-dimensional (2D) gel electrophoresis. The proteins were then stained with silver or colloidal coomassie blue to produce a high-resolution map of the proteome.

Objective: To evaluate the effect of Ginkgo biloba extract (GBE) on neuronal apoptosis in rabbits with kaolin-induced syringomyelia.
Methods: Twenty-four of 30 Chinese white rabbits were subjected to injection of 25% kaolin mixed with equal volume (0.6 ml) of cerebrospinal fluid drawn from the cisterna magna under ketamine anesthesia.
Objective: To investigate the molecular mechanisms of Alzheimer's disease by comparing global protein patterns in two-dimensional electrophoregram (2-DE) of the brain of rats with intrahippocampal amyloid beta injection and normal rats.
Methods: From adult SD rats with intrahippocampal injection of amyloid beta, 200 microg brain proteins were extracted with 9 mol/L urea, 4% CHAPS, 1% DTT, 0.5% CA and a cocktail of protease inhibitors.
