(Basidiomycota, Mycenaceae), a new species of sect. from China.

Background: (Pers.) Roussel (1806) is a large genus of Mycenaceae known for having small to medium-sized basidiomata. It is typified by the species (Scop.

Retinal nerve fiber layer characteristics in patients with spontaneous intracranial hypotension: a retrospective case series.

Objective: To evaluate changes in retinal nerve fiber layer (RNFL) and macular thicknesses, included ganglion cell-inner plexiform layer (GCIPL) thickness, in patients with spontaneous intracranial hypotension (SIH).

Methods: This was a retrospective, nonrandom, observational case series study. Comprehensive ophthalmic examinations and systemic examinations were performed.

[Preretinal hemorrhage and prognosis following vitrectomy and silicone oil tamponade for severe proliferative diabetic retinopathy].

Objective: To examine the prognosis of preretinal hemorrhage following vitrectomy and silicone oil tamponade for severe proliferative diabetic retinopathy.

Methods: Clinical data of 76 cases of proliferative diabetic retinopathy treated with vitrectomy and silicone oil infusion tamponade in Sir Run Run Shaw Hospital from October 2006 to September 2013 were retrospectively reviewed. Intraoperative bleeding,postoperative preretinal bleeding,blood reabsorption time, and preretinal fibrosis were assessed.

Establishment of rat model of central venous catheter (CVC): associated infection and evaluation of the virulence of bacterial biofilms.

In this study, a central venous catheter (CVC)-associated infection model was established in rats to investigate and evaluate the effect of biofilms on the virulence of the pathogens. Twenty-four adult SD rats were randomly divided into biofilm positive (BF+) and biofilm negative (BF-) groups to be challenged with strains of S.epidermidis.

Risk factors related to chronic rhegmatogenous retinal detachment.

Aim: To evaluate the clinical factors related to chronic rhegmatogenous retinal detachment (RRD).

Methods: A retrospective case-control study. A total of 103 consecutive patients (103 eyes) with primary RRD were studied to evaluate the clinical factors related to chronic RRD.

[Effects of exogenous NO3- on cherry root function and enzyme activities related to nitrogen metabolism under hypoxia stress].

A water culture experiment with controlled dissolved oxygen concentration was conducted to explore the effects of exogenous NO3- on the root function and enzyme activities related to nitrogen metabolism of cherry (Prunun cerasus x P. canescens) seedlings under hypoxia stress. Comparing with the control (7.

Comparative analysis of headspace volatiles of Chinese Rosa rugosa.

The floral headspace compounds of Chinese Rosa rugosa germplasms that were isolated by an automated headspace sampler with built-in trap, and followed by gas chromatography-mass spectrometry for identification and quantification. Up to 33 volatile compounds were identified from the 23 rose germplasms, including nine alcohols, five esters, three alkanes, 10 terpenes, three aldehydes, two ketones, and one ether. The main floral components identified were 2-phenylethanol, β-citronellol, ethanol, and n-hexane.

A Serratia marcescens OxyR homolog mediates surface attachment and biofilm formation.

OxyR is a conserved bacterial transcription factor with a regulatory role in oxidative stress response. From a genetic screen for genes that modulate biofilm formation in the opportunistic pathogen Serratia marcescens, mutations in an oxyR homolog and predicted fimbria structural genes were identified.
