Elsinochrome (ESC), light-activated, nonhost-selective phytotoxin, is produced by many members of the genus Elsinoë and required for full virulence of the fungus. It appears that approaches disrupting the ESC production will likely reduce disease severity caused by Elsinoë pathogens. In this study, the influence of nutritional and environmental factors on ESC biosynthesis by the citrus scab pat...

Stellera chamaejasme L. has been widely used in the treatment of lung, liver and esophageal cancer in Chinese traditional medicine. In our previous study, we found that the extract of Stellera chamaejasme L. (ESC) inhibited the growth and induced the apoptosis of human lung cancer NCI-H157 cells. In the present study, we investigated the cellular effects of an ESC-2 extract isolated from ESC in...

Stem cells (SC) exhibit a unique capacity for self-renewal in an undifferentiated state. It is unclear whether the self-renewal of pluripotent embryonic SC (ESC) and of tissue-specific adult SC such as hematopoietic SC (HSC) is controlled by common mechanisms. The deletion of transcription factor Zfx impaired the self-renewal but not the differentiation capacity of murine ESC; conversely, Zfx o...

Embryonic stem cells (ESC) have been established previously from the inner cell mass cells of mouse blastocysts. In suspension culture, they spontaneously differentiate to blood-island-containing cystic embryoid bodies (CEB). The development of blood vessels from in situ differentiating endothelial cells of blood islands, a process which we call vasculogenesis, was induced by injecting ESC into...

To the Editors: In their recent publication, Swati S. Sathe and Peter J. Harte (Mech. Dev. 52,77-87, 1995) claim to have "reisolated' the extra sex combs (esc) gene of Drosophila from our published transgenic stock (Frei et aI., EMBO J. 4,979-987, 1985) by inverse PCR, using P element and rosy primers. This description is wrong because our published transgenic stock carried the esc trans gene w...

Abstract: This paper presents an approach to real-time dynamic simulation of vehicles with electronic stability control (ESC). The approach involves the integration of ESC software into the powertrain and brake models of the realtime vehicle dynamic simulation environment of the National Advanced Driving Simulator (NADS). The ultimate goal of this integration is the use of ESC equipped vehicles...

BACKGROUND Previous studies assessed bone remodeling after a single tooth extraction; however, the effect of multiple contiguous teeth extractions around immediate implant remains unknown. The aim of this microcomputed tomographic investigation is to analyze the alveolar bone remodeling around immediate implants placed in accordance with the extraction socket classification (ESC). METHODS Und...

OBJECTIVE To study the effect of GnRH-II on the cell proliferation, apoptosis and secreting vascular endothelial growth factor (VEGF) of ectopic, eutopic and normal endometrial stromal cells (ESC) from patients with or without endometriosis (EMs) in vitro. METHODS The ectopic, eutopic and normal ESC were isolated, cultured and identified, then added 0 M, 10(-10) M, 10(-8) M, 10(-6) M GnRH-II....
