Cerebrovascular endothelial dysfunction is involved in the progression of leukoaraiosis. Asymmetric dimethylarginine is a competitive inhibitor of nitric oxide, which is highly expressed in patients with leukoaraiosis. Dimethylarginine dimethylaminohydrolase (DDAH) is a hydrolytic enzyme that is primarily responsible for eliminating asymmetric dimethylarginine, and it plays a role in the pathogenesis of cardiovascular and cerebrovascular diseases.

Introduction: The identification of xenobiotic-induced skeletal muscle toxicities through the detection of biomarkers in nonclinical studies can be useful early in the drug discovery process to aid in candidate drug decisions. Skeletal muscle troponin I (sTnI) has been identified as a potential marker of skeletal muscle injury in humans and animals. When skeletal muscle tissue is injured, sTnI is released into circulation.

The evaluation of the potential immunogenicity of therapeutic proteins in nonclinical safety studies has become complicated by the development of biopharmaceuticals that are dosed at high concentrations and/or have long half lives. These products remain in the circulation of the test system for extended periods of time, resulting in samples containing high concentrations of drug that interfere with standard immunogenicity assays. This protocol describes a novel solid-phase extraction with acid dissociation (SPEAD) sample treatment that removes the interfering therapeutic protein "drug" from the sample prior to performance of a direct immunoassay for detection of anti-drug antibodies (ADA).

Cases of atypical glandular cells (AGC) diagnosed on liquid-based preparations were culled from a 3-year period. When available, residual cellular material was analyzed for human papillomavirus (HPV) by polymerase chain reaction and correlated with cytologic and histologic (biopsy) outcome. Of 178,994 cytologic cases, 187 (0.

Objective: This study related morphologic subtype, human papillomavirus status, and a second cytologic examination to the follow-up biopsy-proven high-grade squamous intraepithelial lesion (HSIL; grade II or III cervical intraepithelial neoplasia) after a cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS).

Study Design: Seven hundred four liquid-based cervical cytology specimens were classified as normal, "ASCUS, favor reactive" (AFR), "ASCUS, not otherwise specified," "ASCUS, favor low-grade squamous intraepithelial lesion," "ASCUS, favor HSIL" (AFHS), low-grade squamous intraepithelial lesion, and HSIL. Human papillomavirus typing used polymerase chain reaction-restriction fragment length polymorphism analysis.
