esults: At 40-Hz stimulation, SZ and AFF had significantly reduced phase locking compared with HC. This deficit was more pronounced ver the left hemisphere in SZ. Evoked power at 40 Hz was also reduced in the patients compared with HC. At 30-Hz stimulation phase ocking and evoked power were reduced in both patient groups. The 20-Hz ASSR did not differ between groups, but phase locking and voked...

The effects of chrysotile on DNA synthesis in the gastrointestinal tract of the rat were studied by measuring the uptake of tritium-labeled thymidine; whole stomach, small intestine, colon liver were removed, cleaned, and homogenized and the DNA was isolated and assayed for tritium label.A dose-response study indicated that 2 weeks after a 5 mg/kg dose of chrysotile, DNA synthesis was increased...

We have quantitated the production of thymine glycols in DNA following treatment of cultured human fibroblasts or DNA in solution with the carcinogen N-hydroxy-2-naphthylamine. Thymine glycols, detected by using a monoclonal antibody specific to this base damage, were produced in DNA in a dose dependent manner both in vitro and in vivo. Exposure of DNA to N-hydroxy-2-naphthylamine in the presen...

Invasive methods for prenatal diagnosis include chorionic villus sampling (CVS) and amniocentesis that entail the risk of fetal loss and mortality. During pregnancy, fetal cells including fetal DNA crossed the placenta and within maternal peripheral blood those valuable sources of the sex and genetics information fetuses. It is demonstrated fetal DNA in plasma and serum from healthy pregnant wo...

Protection in experimental rabbit syphilis has been previously assessed by lesion development following intradermal challenge with Treponema pallidum. We have recently reported that passive immunization using monoclonal antibody M131 conveys partial protection as evidenced by significant lesion delays following intradermal challenge. To determine whether such delays in time to lesion appearance...

We have quantitated the production of thymine glycols in DNA following treatment of cultured human fibroblasts or DNA in solution with the carcinogen A/-hydroxy-2-naphthylamine. Thy mine glycols, detected by using a monoclonal antibody specific to this base damage, were produced in DNA in a dose dependent manner both in vitro and in vivo. Exposure of DNA to W-hydroxy2-naphthylamine in the prese...

Chronic hepatitis B virus (HBV) infection is a worldwide problem and HBV reactivation following anticancer chemotherapy has become an emerging clinical challenge. However, the mechanisms of HBV reactivation following chemotherapy remain unclear. Epirubicin is an anthracycline drug used in chemotherapy to treat numerous types of malignancy, including breast cancer, acute leukemia, malignant lymp...

Genome integrity relies on precise coordination between DNA replication and chromosome segregation. Whereas replication stress attracted much attention, the consequences of mitotic perturbations for genome integrity are less understood. Here, we knockdown 47 validated mitotic regulators to show that a broad spectrum of mitotic errors correlates with increased DNA breakage in daughter cells. Une...
