AIM To investigate the feasibility of fast track clinical pathway for esophageal tumor resections. METHODS One hundred and fourteen patients with esophageal carcinoma who underwent esophagogastrectomy from January 2006 to October 2007 in our department were studied. Fast track clinical pathway included analgesia control, fluid infusion volume control,(More)
The condition of the brain parenchyma in cases of vascular dementia and other cerebrovascular conditions may be influenced by structural and functional changes of the terminal intracerebral blood vessels. Arterioles can develop obliterative lesions, capillaries and postcapillary venules can be altered, causing edema. The first part of this review is focused(More)
Michael addition reaction of Chitosan (CS) and polyethylene glycol diacrylate (PEGDA) was carried out successfully in acidic solution. Films with CS/PEGDA weight ratios from 100/0 to 0/100 in 10% increments were analyzed by Fourier transform infrared (FTIR) spectroscopy, Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD). Additionally, the films(More)
Biocompatible carboxyethyl chitosan/poly(vinyl alcohol) (CECS/PVA) nanofibers were successfully prepared by electrospinning of aqueous CECS/PVA solution. The composite nanofibrous membranes were subjected to detailed analysis by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and X-ray diffraction (XRD). SEM images showed that(More)
An iron induced model of posttraumatic chronic focal epilepsy in rats was studied with respect to extracellular amino acids, electrophysiology, and morphology, approx. 6 months after intracortical injection of ferrous chloride. Twenty-six of the twenty-eight (93%) rats developed spontaneous epileptiform EEG-activity and electrical cortical stimulation done(More)
In order to investigate the effects of different terms of inhaled nitric oxide (NO) preconditioning with low concentration on the activations of Toll-like receptor 2 and 4 (TLR2/4) in the lung ischemia-reperfusion (IR) injury in mice, we divided the male C57BL mice into five groups: sham (S) group, IR group, NO 1-min preconditioning group (15 ppm NO(More)
BACKGROUND The development of rapid and safe antidepressants for the treatment of major depression is in urgent demand. Converging evidence suggests that glutamatergic signaling seems to play important roles in the pathophysiology of depression. METHODS We studied the antidepressant effects of 3(')-deoxyadenosine (3'-dA, Cordycepin) and the critical role(More)
In this study, alginate/chitosan layer-by-layer composite coatings were prepared on titanium substrates via electrodeposition. The mechanism of anodic deposition of anionic alginate based on the pH decrease at the anode surface, while the pH increase at the cathode surface enabled the deposition of cationic chitosan coatings. The surface of coatings was(More)
Porous scaffolds composed of alginate (AG) and chitosan (CS) were fabricated by combining the formation of polyelectrolyte complex (PEC) with freeze-drying. The AG scaffold was used as a framework with uniformly distributed and interconnected pore structure. The chitosan or chitosan/hydroxyapatite (CS/HA) composite solution was introduced into the pores of(More)
A two-component tissue adhesive based on biocompatible and bio-degradable polymers (oxidized urethane dextran (Dex-U-AD) and gelatin) was prepared and photocrosslinked under the ultraviolet (UV) irradiation. The adhesive could adhere to surface of gelatin, which simulated the human tissue steadily. The structures of above Dex-U-AD were characterized by(More)
