Hydroxyapatite (HA) bioceramic coating has been extensively applied for the modification of metallic implants to improve their biocompatibility and service life after implantation. Unfortunately, HA coating often suffers from high friction, severe wear, and bacterial invasion, which restrict its application in artificial joints. According to a bioinspired soft/hard combination strategy, a novel HA composite coating that is infiltrated with a vancomycin-loaded graphene oxide (GO) hybrid supramolecular hydrogel is developed vacuum infiltration and a subsequent host-guest interaction-induced self-assembly process.

Inspired by the structure and dynamic weeping lubricating mechanism of articular cartilage, a novel composite coating composed of a textured YO-stabilized ZrO (YSZ) ceramics reservoir and silver nanoparticles (AgNPs) hybrid supramolecular hydrogel was developed on the basis of a soft/hard combination strategy. The precursor solution including the poly(ethylene glycol) (PEG)-modified AgNPs and α-cyclodextrins (α-CDs) could be infiltrated deep into (50-60 μm) the pores of a textured YSZ ceramics substrate by a vacuum infiltration method, forming a supramolecular hydrogel within the pores through host-guest inclusion between α-CDs and PEG chains distributed onto the surface of AgNPs. The AgNPs hybrid hydrogel showed thixotropic and thermoresponsive gel-sol transition behavior, low cytotoxicity, and excellent drug-loading capacity, as well as significant antibacterial properties.

Odontogenic ameloblast associated protein (ODAM) is a protein contributed to cell adhesion and has been shown to express in normal prostate tissue, but the expression and significance of ODAM in prostate cancer remain unknown. In this study, we detected the protein expressions of ODAM in 88 prostate cancer tissues with immunohistochemical staining, and found that 53 cases (60.2%) was high expression of ODAM, which was shown in the cytoplasm and paranuclear regions.

Currently, there are no well-established preoperative clinicopathological parameters for predicting extra-prostatic extension (EPE) in patients with clinically localised prostate cancer (PCa). The transmembrane protease serine 2 ()-ETS-related gene () fusion gene is a specific biomarker of PCa and is considered a prognostic predictor. The aim of the present study was to assess the value of this marker for predicting EPE in patients with clinically localised PCa.

Background: Perivesical fat invasion is considered as an important prognostic factor for bladder cancer. However, the predictive role of perivesical fat invasion in invasive bladder cancer prognosis has never been reported in Chinese patients. The aim of the study was to assess the predictive value of perivesical fat invasion for prognoses of T2 and T3 bladder cancer in Chinese patients.

Background And Objective: The most effective therapy against renal cell carcinoma (RCC) is surgical treatment; however, there have been few large-scale studies that focused on the oncological outcome of this disease in China. The aim of the current study was to report the clinicopathological results and cancer-specific survival (CSS) rate in RCC patients after surgical treatment in our center.

Methods: We retrospectively analyzed the clinicopathological data of 336 RCC patients who underwent radical or partial nephrectomy between 1999 and 2006.

Objective: To analyze the incidence of benign lesions in Chinese patients undergoing nephrectomies for renal masses identified as localized renal cell carcinoma (RCC) in preoperative imaging.

Methods: Between 1999 and 2007, 303 patients (112 female, 191 male) with presumed localized RCC underwent nephrectomy (234 radical nephrectomies and 69 partial nephrectomies). Preoperative computed tomography images and pathological findings were reviewed and analyzed.

Objectives: To introduce a modified technique for preventing complications related to stoma and ileoureteral anastomosis in patients undergoing ileal conduit diversion.

Methods: A urinary stoma was created intracorporeally and was pulled out to the abdominal wall through a retroperitoneal tunnel. The ileal conduit was fixed by nonabsorbable sutures that incorporated all abdominal wall fascia and the bowel seromuscular layer.

The alternative pathway (AP) respiration of plants is a cyanide-resistant and non-phosphorylating electron transport pathway in mitochondria. Alternative oxidase (AOX) is the terminal oxidase of the AP and exists in plant mitochondria as two states: the reduced, noncovalently linked state or the oxidized, covalently cross-linked state. In the present study, the effects of 20 microM exogenous salicylic acid (SA) on both AP activity and AOX expression in mitochondria of tobacco (Nicotiana rustica L.

The changes in cyanide-resistant respiration and metabolism of active oxygen species in drought-sensitive and drought-resistant wheat seedlings under water stress were studied. In general, drought stress decreased the level of cyanide-resistant respiration and AOX1 mRNA content in wheat seedling leaves. But the drought-resistant cultivars, which had much higher level of cyanide-resistant respiration and AOX1 mRNA content than the drought-sensitive ones, presented an ability to adapt to mild drought stress.
