Background and Purpose: The etiology of stroke in the young is different from that in older patients and remains unknown in almost one third of the cases. To gain further insight into both pathogenic and etiologic determinants, we prospectively studied a large number of consecutive young adults with focal cerebral ischemia. Methods: Three hundred thirty-three patients aged 15-44 years with tran...

to identify the alternaria spp. pathogenic to tomato and potato, surveys of tomato and potato fields were made during 2009- 2010 in west azerbaijan province. in total about 261 isolates belonging to alternaria genus were isolated and purified. based on morphological studies 6 species, namely: a. alternata, a.tenuissima, a. interrupta, a. arborescense, a. brassicina and a. tomatophila from tomat...

background: naegleria is a free-living amoeba, and pathogenic naegleria may pose a health risk to people exposed to recreational water. our objective in this study was to determine if there are pathogenic amoebae in environmental water samples from changchun, northeastern china. methods: during july to september 2012, a total of 70 water samples were collected from changchun, northeastern china...

diseased samples with root rot symptoms were collected from different sugar beet growing areas. from rotted roots, 20 fungal isolates were identified as fusarium solani based on morphological characteristics .pathogenecity of the isolates was studied in in vitro condition on sugar beet roots. the results showed pathogenic variability among the isolates. cluster analysis divided the isolates int...

garlic and onion are very important crops which are cultivated especially in autumn season in jiroft region, southeast of iran. one of the limiting factors for development of cultivation of these crops is fungal diseases such as leaf spot and blight. for identifying the causal agents of this disease, numerous onion and garlic fields were surveyed during 2001-2003 and infected samples were colle...

results the lipl32 sequences were >94% homologous among the vaccinal and other pathogenic leptospira serovars in genbank. this result indicates the conservation of this gene within the pathogenic leptospires. conclusions the cloned gene in this study may provide a potentially suitable platform for development of a variety of applications such as serological diagnostic tests or recombinant vacci...

Background Cardiac myxomas are benign tumors that commonly arise within the left atria. Familial cardiac myxomas are a part of Carney Complex (CNC), an autosomal dominant multiple neoplasia syndrome caused by germline mutations in PRKAR1A. Seven percent of cardiac myxomas are associated with CNC. To date, the genetic basis of isolated cardiac myxomas (ICM), however, has not been fully elucidate...

Most highly pathogenic avian influenza viruses (AIV) emerge after field passage of non-pathogenic AIVs in birds. The outbreak of low-pathogenic H7N1 avian influenza virus in Italy during 1999-2000 followed by outbreak of highly pathogenic H7N1 avian influenza virus is one example in this regard. This experiment has been designed to investigate the effect of pre-infection of birds with LPAI on s...

Amelogenin gene (AMEL-X) encodes an enamel protein called amelogenin, which plays a vital role in tooth development. Any mutations in this gene or the associated pathway lead to developmental abnormalities of the tooth. The present study aims to analyze functional missense mutations in AMEL-X genes and derive an association with amelogenesis imperfecta. The information on miss...
