University of California, Davis (UCD) line 200 White Leghorn Chickens spontaneously develop a syndrome that has many analogous features to human progressive systemic sclerosis. This syndrome is characterized by progressive involution of comb, dermal fibrosis, and distal polyarthritis. These three features occur within 6 wk after hatching, and are accompanied by a 40% mortality as a result of va...

Wild and cultivated Basidiomycetes species were cultured to determine the distribution of bacteria causing brown blotch disease of Agaricus bisporus. Colonies from each basidiocarp were screened for brown blotch organisms by the white line and host pathogenicity tests. Isolates causing brown blotch were identified as Pseudomonas tolaasi and an Arthrobacter species.

Background: Leukemia is a malignant proliferative disorder of the hematopoietic cells. The important role of angiogenesis in leukemia has been reported by several studies. Matrix metalloproteinases (MMPs) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. Objective: The present study was conducted to evaluate the patterns of ...

in order to study the response of new sugar beet hybrids and cultivars to curly top disease in the field conditions, an experiment was carried out in a randomized complete block design with four replications and sixteen treatments in 2007 in fasa. each plot included a hybrid or cultivar planted in three rows with eight meter length and 50cm between- row spacing. after weeding and first thinning...

Fish infected with Ich may have white specks on their skin as though they were sprinkled with salt (Fig. 1). Because of this appearance, Ich is sometimes called white spot disease. The skin of the fish may also look bumpy. Mature forms of the parasite are large (up to 1 mm or 1/32 inch across) and can be seen without magnification. Ich often causes the fish to have large amounts of mucus slough...

Vanishing white matter disease 1 (VWM) is a puzzling leukoencephalopathy caused by mutations in any of the five genes encoding eukaryotic translation initiation factor 2B (eIF2B), an ubiquitously expressed protein complex with a crucial role in initiation of mRNA translation for virtually every protein in the human body. VWM is one of the most prevalent inherited childhood white matter disorder...

In the photolithography processing of semiconductor, line width is smaller and smaller. Therefore, the requirements of process window are stricter than before. In the small line width, the formation of serious white wall will affect line width and cause rejects in following process. The study conducted research on the control of best focus in which particularly explored the relationship between...

High-cadence, multiwavelength optical observations of a solar active region (NOAA 10969), obtained with the Swedish Solar Telescope, are presented. Difference imaging of white light continuum data reveals a white light brightening, 2 min in duration, linked to a co-temporal and co-spatial C2.0 flare event. The flare kernel observed in the white light images has a diameter of 300 km, thus render...

In the developed countries, many organizations are regarded a...

Coral diseases have caused a substantial decline in the biodiversity and abundance of reef-building corals. To date, more than 30 distinct diseases of scleractinian corals have been reported, which cause progressive tissue loss and/or affect coral growth, reproductive capacity, recruitment, species diversity and the abundance of reef-associated organisms. While coral disease research has increa...
