DNAs that encode the mating-type functions (mat+ and mat-) of the filamentous fungus Podospora anserina were cloned with the use of the mating-type A probe from Neurospora crassa. Cloning the full mat information was ascertained through gene replacement experiments. Molecular and functional analyses of haploid transformants carrying both mating types lead to several striking conclusions. Mat+ m...
Pseudo-homothallism is a reproductive strategy elected by some fungi producing heterokaryotic sexual spores containing genetically different but sexually compatible nuclei. This lifestyle appears as a compromise between true homothallism (self-fertility with predominant inbreeding) and complete heterothallism (with exclusive outcrossing). However, pseudohomothallic species face the problem of m...
لپتوسپیروز یکی از شایعترین بیماری مشترک بین انسان و دام از حدود نیم قرن پیش بوده که تا کنون گزارش های مختلفی از وقوع آن در انسان و دامها گزارش شده است. بررسی انجام شده در بسیاری از نقاط ایران حاکی از افزایش شیوع آن در بین جمعیت مذکور است. هدف از مطالعه حاضر تعیین میزان شیوع سرولوژیک لپتوسپیرا در گاوها و گوسفندها در ارومیه بود. برای این منظور نمونه خون از تعداد 203 راس گاو و 166 راس گوسفند...
Aimed at investigating the recovery of a specific mutant allele of the mating type locus (MAT) by switching a defective MAT allele, these experiments provide information bearing on several models proposed for MAT interconversion in bakers yeast, Saccharomyces cerevisiae. Hybrids between heterothallic (ho) cells carrying a mutant MAT a allele, designated mata-2, and MAT alpha ho strains show a h...
Medication-assisted treatment (MAT) is underutilized in the treatment of drug-dependent, criminal justice populations. This study surveyed criminal justice agencies affiliated with the Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) to assess use of MAT and factors influencing use of MAT. A convenience sample (N = 50) of criminal justice agency respondents (e.g., jails, prisons, parole/...
To understand the molecular properties of matrilin-3, a newly discovered member of the novel extracellular matrix protein family, we cloned a MAT-3 cDNA from developing chicken sterna. Real time quantitative reverse-transcription polymerase chain reaction indicates that MAT-3 mRNA is mainly expressed in the proliferation zone of a growth plate. It is also expressed in the maturation zone, overl...
Toxoplasma gondii infects all species of warm-blooded animals, including humans, and domestic cats and other felidae are its definitive hosts. The aim of the present survey was to compare serological and molecular tests in accurate diagnosis of T. gondii infection among stray cats in Ahvaz, Iran. A total of 100 cats were examined for the detection of serum antibodies against T. gondii (chronic ...
background: neospora caninum , an obligate intracellular protozoan parasite, is recognized as a major cause of abortion in cattle, while limited information is presently available on the seroprevalence of neospora antibodies in horses' worldwide .the aim of the present study was to determine serologic prevalence of neospora infection in horses in iran. methods: sera from 150 horses from mashh...
