Phytophthora capsici is a soilborne oomycete plant pathogen that causes severe vegetable crop losses in New York (NY) state and worldwide. This difficult to manage, part due its production of long-lasting sexual spores tendency quickly evolve fungicide resistance. We single nucleotide polymorphism (SNP) genotyped 252 P. isolates, predominantly from NY, order conduct genome-wide association stud...

The chromosomal spread and karyotype of Bleak (Alburnus alburnus) from Anzali lagoon were identified using tissue squashing techniques with injection of 0.5ml/100g body weight of 0.01% Colchicines solution in fish fingerlings. Kidney and gill tissues were then extracted and chopped in KCl 0.045M for 20 min and fixed in Carnoy solution in 3 stages. The chromosomal spreads were stained in 20% Gim...

The indications and results of cytogenetic analysis of 521 amniotic cell cultures performed at 13-16 weeks of gestation were evaluated in this study. 507 fetuses (97.3%) were cytogenetically normal, 14 (2.7%) had unbalanced karyotypes, and 2 fetuses were found to have major abnormalities, one with anencephaly detected by measurement of alpha -fetoprotein levels in amniotic fluid and ultraso...

Abstract Noninvasive prenatal testing (NIPT) has revolutionized the screening methods for fetal chromosomal aneuploidies with high utility common chromosomes 13,18, 21, X and Y. Trisomy 13 is often associated major minor malformations can be screened by antenatal scan first- second-trimester biochemical screening. We describe a case risk trisomy on NIPT, but without any abnormalities scan. As r...

We evaluated the effect of restriction and modification genes expressed in Campylobacter jejuni, a naturally competent organism, on transformation efficiency. Fourteen strains C. jejuni were tested for sensitivity to 29 enzymes. Strains that showed same susceptibility pattern by either agarose gel electrophoresis or PFGE grouped together. Natural between within groups was assessed using two chr...

introduction: robertsonian translocation is one of the major chromosomal rearrangements with a prevalence rate of 0.1% of the general population and 1% of the infertile population. in this report, we present a nonhomologous robertsonian translocation in a female patient with a history of repeated abortions. case presentation: a couple with the complaint of repeated abortions was admitted in the...

Background: Rapidly increasing possibilities of exposure to environmental extremely low-frequency electromagnetic fields (ELF-EMF) have become a topic of worldwide investigation. Epidemiological and laboratory studies suggest that exposure to ELF-EMF may increase cancer risk therefore assessment of chromosomal damage in various cell lines might be of predictive value for future risk es...

The most significant complication of pregnancy is recurrent miscarriage. Numerous factors have been described as associations with recurrent wastage such as: uterine abnormalities, immunological factors, endocrinologic imbalance and chromosomal defects. Cytogenetic evaluation of couples with recurrent pregnancy losses is performed on the basis of G-banding technique only after other possible et...
