Anatomical, kinematic and ablation studies were performed to evaluate the contribution of elasticity in use of the cockroach tarsus (foot) in walking. The distal tarsus (claws and arolium) engages the substrate during the stance phase of walking by the action of a single muscle, the retractor unguis. Kinematic and ablation studies demonstrated that tarsal(More)
BACKGROUND We conducted a meta-analysis of patients with coronary heart disease (CHD) to determine the effectiveness of statin therapy; whether effectiveness varied according to patient characteristics, outcomes, or pretreatment low-density lipoprotein cholesterol (LDL-C) levels; and the optimal LDL-C goal and the level at which to initiate statin therapy.(More)
Repetitive hydatidiform mole was observed in four pregnancies. The pregnancies presented with heavy bleeding and vomiting, but the post-evacuation courses were uncomplicated, with rapid regression of serum hCG levels. Cytogenetic investigations, analyses of restriction fragment length polymorphisms, and flow cytometry in three pregnancies were consistent(More)
To examine how walking patterns are adapted to changes in load, we recorded leg movements and muscle activities when cockroaches (Periplaneta americana) walked upright and on an inverted surface. Animals were videotaped to measure the hindleg femoro-tibial joint angle while myograms were taken from the tibial extensor and flexor muscles. The joint is(More)
Many types of sense organs have been demonstrated to show repetitive discharges during walking that could provide informational cues about leg movements and other parameters of locomotion. We have recorded activities of receptors of the distal (tarsal) segments of the cockroach hindleg in restrained and freely moving animals while they were videotaped.(More)
PURPOSE We report on two children who presented with hyperuricemia and acute renal failure (admission uric acid levels 57.4 and 59.2 mg/dl). RESULTS Both were subsequently diagnosed to have acute lymphoblastic leukemia, despite normal initial complete blood counts and peripheral smear. Neither patient had nephromegaly on renal ultrasound. CONCLUSIONS(More)
Combination laser conization was performed in 469 patients for the treatment of cervical intraepithelial neoplasia (CIN). In 58 cases (12.4%), CIN was located in the margins of the cone. Fifty-one patients with involvement of the margins were evaluated by cytologic examination, using the Ayre spatula and the Cytobrush, and by cervical biopsy and(More)
During 4 years, 1980-1984, 197 patients were treated for CIN II and CIN III by cryosurgery. Included were 62 patients with endocervical involvement (positive ECC). The cure rates of a single cryosurgical treatment were lowered significantly by increasing grade of CIN and by endocervical involvement. The factors influencing the cure rates of cryosurgery are(More)
Quantitation of T-lymphocyte subsets and natural killer cells in peripheral blood of 16 patients with cervical intraepithelial neoplasia and 15 controls with normal cervical cytology was performed using specific monoclonal antibodies and flow cytometry. No differences were observed in T-helper lymphocytes, T-suppressor/cytotoxic lymphocytes, Th/Ts cell(More)
