Background: Eucalyptus bacterial wilt caused by Ralstonia solanacearum is an important eucalyptus disease. Endophytic fungi, an important source of natural active substances, provide a new breakthrough for the control of plant diseases.
Results: In the present study, 80 endophytic fungal isolates were obtained from the healthy branches and fruits of Eucalyptus exserta.
A new -terphenyl derivative 4″-deoxy-2'-methoxyterphenyllin (1), along with six known -terphenyl derivatives (2-7), a known flavonoid derivative dechlorochlorflavonin (8) and a known fellutanine A (9), were isolated from the insect-derived strain of the fungus Bdf-2, associated with . The structure of 1 was established by the analysis of the 1D and 2D NMR and HR-ESI-MS spectra. Compounds 1-9 were evaluated for antibacterial activities against ATCC29213, ATCC25922 and , and for antioxidant activities.

As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages.

Purpose: To investigate the effect of inflammatory cytokines on the activity of the human MUC5AC promoter in vitro and in vivo.
Methods: Conjunctival epithelial cells transfected with MUC5AC-luciferase plasmids challenged with different cytokines (tumor necrosis factor-alpha [TNF-alpha], interleukin [IL]-1beta, IL-2, IL-6, and IL-8) at various concentration (1, 10, 20, 50, 100, 200, 500, 1000, and 2000 pg/mL) for 24 hours. A Helio Gene Gun system (Bio-Rad Laboratories, Hercules, CA, USA) was used to deliver MUC5AC-luciferase plasmids into rabbit conjunctivas, which were also challenged with these cytokines (1000 pg/mL) at the frequency of every six hours for 48 hours.
We report a case of a persistent pupillary membrane (PPM) associated with a cataract managed by sequential argon-YAG laser membranectomy and phacoemulsification. A 30-year-old woman had an extensive PPM and anterior capsular opacity of the lens in the right eye. Best corrected visual acuity (BCVA) was 20/60.
