this paper presents a case-report of cutaneous actinomycosis due to actinomyces viscosus in a 22 year old man, hospital staff from tehran with multiple fistulous tracts in his right hand and a history of skin injury due to thorn of plant. diagnosis was based on the observation of gram positive coccoid, diphtheroid and long branching filaments in direct examination of pus from fistulous tracts a...

The family Simuliidae is the host of simbiontes fungi that inhabit the digestive tracts of arthropods. This paper reports the presence of fungi in Simulium goeldii Cerqueira & Nunes de Mello larvae in Amazonia. We observed that the larvae are a good component of aquatic systems to isolate filamentous fungi.

In the nuclear genome of Saccharomyces cerevisiae, simple, repetitive DNA sequences (microsatellites) mutate at rates much higher than nonrepetitive sequences. Most of these mutations are deletions or additions of repeat units. The yeast mitochondrial genome also contains many microsatellites. To examine the stability of these sequences, we constructed a reporter gene (arg8(m)) containing out-o...

statistical studies on palynology contents of late cretaceous to paleocene age gurpi formation in a surface section in zagros basin,sw iran indicate changes in abundance, species diversity, ratio of spiniferites to cyclonephelium (s/c), palynological marine index(pmi) values and organic facies. these palynological variations clearly reflect fluctuations in relative sea-level and depositionalenv...

Objective To investigate groups of thalamic nuclei (anterior, posterior, medial, lateral) and the integrity of their associated tracts with regard to cognitive and neuropsychiatric symptoms in multiple sclerosis (MS) patients. Methods Conventional MRI and diffusion tensor imaging (DTI) was acquired in 73 MS patients and 18 healthy controls. Extensive neuropsychological testing was performed and...

Expansions of trinucleotide GAA•TTC tracts are associated with the human disease Friedreich's ataxia, and long GAA•TTC tracts elevate genome instability in yeast. We show that tracts of (GAA)(230)•(TTC)(230) stimulate mitotic crossovers in yeast about 10,000-fold relative to a "normal" DNA sequence; (GAA)(n)•(TTC)(n) tracts, however, do not significantly elevate meiotic recombination. Most of t...
