This application note shows how the Agilent 2100 Bioanalyzer was used in polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) fragment analysis for fish species identification. A 464bp cytochrome-b target sequence, found in all vertebrate fish, was first amplified and then digested with restriction enzymes. The fragments were resolved on the DNA 500 LabChip®, allowing s...

aim : this study aimed to determinant association between rs76189946 polymorphism of egf gene and risk of colorectal cancer in an iranian population. background : colorectal cancer (crc) is the third most prevalent cancer in both genders worldwide. the determination of genetic variation becomes a new way to etiology of colorectal cancer. epidermal growth factor (egf) is a mitogen that plays an ...

Background/Aim: Vitiligo is a prevalent inflammatory illness that can affect the skin and mucosal surfaces characterized by patchy loss of pigmentation. Paraoxonase1 (PON1) an esterase enzyme with antioxidant properties binds to high-density lipoproteins. We examined whether PON1 gene Q192R polymorphism risk factor for vitiligo among Turkish people.
 Methods: The study included 70 controls...

Background: Staphylococcus aureus is a common pathogen in human that can be the cause of a wide range of infectious diseases including bacteremia, pneumonia, cellulitis, and osteomyelitis and skin and soft tissue infections. The coagulase enzyme is one of the most important virulence factors of this bacterium. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) Coa...

Background: Coronary artery disease (CAD) is a complex disorder. It thought to be result of gene-gene and gene-environment interactions. was reported that XbaI polymorphism ApoB gene associated with CAD. However, the results were conflicting risk factors not fully studied in previous studies. Aim: estimate association lipid profile, dietary pattern CAD Egyptian population. Subjects Methods: Thi...

conclusions several previous studies used pcr-rflp to genotype hbv; however, we showed the high risk to obtain atypical profiles, especially in advanced stages of chronic infection, with as results difficulties to genotype the virus. these profiles resulted from the accumulation of mutations during natural course of infection resulting in a modification in restriction sites for enzymes. so, we ...

conclusions the results of the present study, compared to the previous studies, showed a significantly lower prevalence of cutaneous candidiasis. among candida species, c. albicans was still the most common infectious agent isolated from clinical samples. shifting toward non-albicans candida species was not confirmed in this study. in addition, our study revealed that there is a direct correlat...

identification  of clinically  significant  nocardia  species  is essential  for the definitive diagnosis, predict antimicrobial susceptibility, epidemiological purposes,  and  for  an  effective  treatment.   conventional   identification   of nocardia species in routine medical laboratories which is based on phenotypic (cellular morphology, colonial characteristics), biochemical and enzymatic...

Toxoplasmosis and leishmaniasis are two worldwide zoonoses caused by the protozoan parasites Toxoplasma gondii and Leishmania spp., respectively. This report describes the clinical and laboratorial findings of a co-infection with both parasites in a 4-year-old female dog suspected of ehrlichiosis that presented anemia, thrombocytopenia, hypoalbuminemia, hyperglobulinemia, tachyzoite-like struct...

OBJECTIVE The aim of this study was to evaluate, by PCR-RFLP and real-time PCR, the yield and quality of genomic DNA collected from buccal cells by mouthwash after different storage times at room temperature. MATERIAL AND METHODS A group of volunteers was recruited to collect buccal cells using a mouthwash solution. The collected solution was divided into 3 tubes, one tube were used for immed...
