[Research on effects of vitamin A palmitate on repair of mechanical corneal epithelial defects and conjunctival goblet cells in rabbits].

Objective: Randomized controlled experimental study to investigate the influence of vitamin A palmitate and bovine recombinant basic fibroblast growth factor (bFGF) on repair of mechanical corneal epithelial defects, conjunctival epithelial cells and goblet cells in rabbits.

Methods: One hundred and twenty New Zealand rabbits (all males) were selected to establish the mechanical corneal epithelial defects models (scratching out a round area with the diameter of 8 mm in the centre of cornea). Forty eight New Zealand rabbits were randomly divided into 4 groups: group A used lincomycin hydrochloride eye drops (LED) after the model had been established; group B used vitamin A palmitate eye gel and LED; group C used recombinant bFGF eye gel and LED; group D used vitamin A palmitate eye gel, bFGF eye gel and LED.

[Polyketide antibiotics produced by polyketide synthase in streptomyces--a review].

Polyketides have played an important role in antibiotic drug discovery with most antibacterial drugs being derived from a natural product or natural product lead. Furthermore, the biosynthetic gene clusters for numerous bioactive polyketides have been intensively studied over the past 15 years. This paper focuses on the polyketide drugs approved by US-FDA and takes a general view in the antibiotics produced by polyketide synthase in streptomyces.

[Sutureless deep lamellar endothelial keratoplasty].

Corneal endothelial dysfunction can severely affect visual acuity. In order to deal with this morbidity, ophthalmologists used to perform penetrating keratoplasty, in which the complications, such as postoperative astigmatism and graft rejection, led to poor visual recovery. If only the Descemet's membrane and endothelium is transplanted, the corneal injury of recipients caused by surgeries would be reduced and better visual acuity recovery might be guaranteed.

Simultaneous pigmented villonodular synovitis and synovial chondromatosis of the temporomandibular joint: case report.

Pigmented villonodular synovitis and synovial chondromatosis are benign nonneoplastic proliferations originating in the synovium of unknown cause. Involvement of the temporomandibular joint (TMJ) is rare. Only 3 cases of simultaneous pigmented villonodular synovitis and synovial chondromatosis involving the TMJ have been reported.

Intra-articular adhesions of the temporomandibular joint: Relation between arthroscopic findings and clinical symptoms.

Background: Intra-articular adhesion (IA) is one of the important pathologic signs of intracapsular temporomandibular joint (TMJ) diseases, but this factor has been rarely described with respect to its arthroscopic characteristics and histology. The purpose of this study was to describe the incidence and distribution of IA in patients with internal derangement (ID) and to investigate the correlation between adhesions and the clinical symptoms of patients with ID of TMJ with closed-lock.

Methods: A retrospective analysis was conducted of 1822 TMJs with ID that were refractory to nonsurgical treatments and underwent arthroscopic surgery between May 2001 and June 2008 in our department.

Histologic study of adhesions in the upper joint compartment of the temporomandibular joint.

Purpose: The aim of this study was to observe the histologic characteristics of adhesions in the upper joint compartment of the temporomandibular joint and investigate the mechanism of genesis.

Patients And Methods: During arthroscopic surgery, we obtained 42 biopsy specimens of different grades of adhesions, ranging from grade I to grade IV, from 21 joints in 21 patients with internal derangement. Two biopsy specimens from each temporomandibular joint were obtained in this study; one was immediately fixed in 4% formalin and examined under a light microscope, and the other was fixed in 2% glutaraldehyde solution and examined under a transmission electron microscope.

Assessing the toxicity of TBBPA and HBCD by zebrafish embryo toxicity assay and biomarker analysis.

Tetrabromobisphenol A (TBBPA) and hexabromocyclododecane (HBCD) are two of the most widely used brominated flame retardants (BFRs). The biological toxicity effect of TBBPA and HBCD was studied by means of zebrafish embryo toxicity assays in combination with three biomarkers, including superoxide dismutase (SOD), lipid peroxidation, (LPO), and heat shock protein (Hsp70). The standard zebrafish embryo assay showed that high concentrations of TBBPA (> or =0.

Genomic and biological characterization of aggressive and docile strains of lymphocytic choriomeningitis virus rescued from a plasmid-based reverse-genetics system.

Arenaviruses include several causative agents of haemorrhagic fever disease in humans. In addition, the prototypic arenavirus lymphocytic choriomeningitis virus (LCMV) is a superb model for the study of virus-host interactions, including the basis of viral persistence and associated diseases. There is little understanding about the molecular mechanisms concerning the regulation and specific role of viral proteins in modulating arenavirus-host cell interactions either associated with an acute or persistent infection, and associated disease.
