Although human papilloma virus (HPV) associated lesions constitute a well recognized clinical entity in the female lower genital tract, namely vulva, vagina and cervix, few studies have demonstrated HPV infection in other genital sites, particularly in the ovary and uterine corpus. Recently, with the highly sensitive polymerase chain reaction (PCR)(More)
Next-generation sequencing has become more widely used to reveal genetic defect in monogenic disorders. Retinitis pigmentosa (RP), the leading cause of hereditary blindness worldwide, has been attributed to more than 67 disease-causing genes. Due to the extreme genetic heterogeneity, using general molecular screening alone is inadequate for identifying(More)
OBJECTIVE To determine the amplification of proto-oncogene HER-2/neu in invasive cervical cancer and its relationship with the stage of disease, grade of tumor and prognosis of patients. METHODS In this retrospective study 70 women with invasive cervical squamous cell carcinoma were included. DNA was extracted from the paraffin-embedded tumor tissue. The(More)
A novel assay for supercoiled and other fully double-stranded forms of hepatitis B virus (HBV) DNA in blood is presented that utilizes molecular hybridisation to a radiophosphorous-labeled oligonucleotide probe. The probe [5'-d(ACGTGCAGAGGTGAAGCGA)] is complementary to the S(+)-strand sequence furthest downstream, at the end of the gap. We examined blood(More)
