DNA-based molecular markers for differentiation of five penaeid shrimps (Penaeus monodon, P. semisulcatus, Feneropenaeus merguiensis, Litopenaeus vannamei and Marsupenaeus japonicus) were developed based on polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and single-stranded conformation polymorphism (SSCP) of 16S ribosomal (r) DNA. Differentiation of P. monodon, P....

Background. Thyroid peroxidase gene (TPO) mutations are one of the most common causes of thyroid dyshormonogenesis in patients with congenital hypothyroidism (CH). In this study, the prevalence of TPO gene mutations in patients with thyroid dyshormonogenesis in Isfahan was investigated. Methods. In this cross-sectional study, genomic DNA of 41 patients with permanent CH due to thyroid dyshormon...

In a search for pathophysiological causes of idiopathic male infertility we investigated the occurrence of mutations of the FSH receptor in 48 men with this disorder. The entire FSH receptor gene was analyzed by single stranded conformation polymorphism analysis (SSCP). A heterozygous point mutation without functional consequences, exchanging Val to Ala in codon 341, was found in one patient. S...

in this study, substitution at codon ser315 of katg gene, a reliable marker for isoniazid (inh) resistance was analyzed and compared by three molecular methods such as dna sequencing, polymerase chain reaction restriction fragment length polymorphism (pcr-rflp) and pcr-single strand conformation polymorphism (pcr-sscp) in 105 phenotypically resistant isolates obtained from various parts of indi...

The genetic diversity of Jamunapari goats (Capra hircus) was investigated using an optimized non-radioactive polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) method to detect α-lactalbumin polymorphism in a sample of 50 goats. Our data show that PCR-SSCP is an appropriate tool for evaluating genetic variability in Jamunapari goats. Polymorphism was detected in the sa...

Calpastatin (CAST) is a specific inhibiter of calpains, playing a role in meat tenderization and myogenesis. In the present study, the polymorphism of the CAST gene of Makoei sheep was investigated by polymerase chain reaction and single strand conformation polymorphism technique (PCR–SSCP). Genomic DNA was extracted from whole blood samples collected from 100 sheep. A 622 bp CAST exon 1 segmen...

We successfully cloned the Wistar-Imamichi (WI) rat growth hormone gene (GenBank accession: GQ890681), which contained 5 exons and 4 introns. Using the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) technique, a novel missense substitution single nucleotide polymorphism was identified and tested for Hardy-Weinberg equilibrium with the χ(2) test. This gene fragment ...

In a joint Brazilian-German case study, distribution patterns of microorganisms were compared with environmental variables in the tropical coastal Manguaba lagoon in northeast Brazil, which is situated downstream of several sugar cane processing plants . 16S rDNA and 16S rRNA single strand conformation polymorphism (SSCP) gene fingerprinting were used to follow the composition and distribution ...

DOI: 10.1002/sscp.202000087 The cover picture shows the application of ultrasound-assisted extraction and liquid-liquid to recover polyhydroxylated polymethoxylated flavones, as well phenolic acids from traditional herbal plant, Orthosiphon aristatus. This is a perennial herb that commonly known Java Tea or Cat's Whiskers. It widely used by people in region Southeast Asia folk remedy for many d...

SKG mouse, as a model of spontaneous rheumatoid arthritis (RA) bred recent years, is similar to the patients with RA. We analyzed the clonotypes of T cell infiltrating into joints of SKG mice in initial stage and late stage of RA by using reverse transcriptase-polymerase chain reaction (RT-PCR) and subsequent single-strand conformation polymorphism (SSCP). The results indicated that the percent...
