Conducting Randomized Trials in the Electrophysiology Laboratory: Lessons from a Randomized Comparison of Recording Methods During Pulmonary Vein Isolation by Segmental Ostial Ablation
(Kluwer Academic Publishers; Springer Science+Business Media, 2003-09)
Accurate identification of pulmonary vein (PV) potentials during segmental ostial ablation for PV isolation is very important to completely isolate the PVs and also to avoid unnecessary applications of radiofrequency energy. ...
Datura stramonium lectin: isolation and characterization of the homogeneous lectin
(Elsevier, 1981-07-20)
The temporal structure of motivation: III. Identification and ecological significance of ultradian rhythms of intracranial reinforcement
(Elsevier, 1980-10)
Adult male Sprague-Dawley rats were stereotactically implanted with intracranial electrodes aimed at the anterior medial forebrain bundle, and trained to self-administer intracranial stimulation. Following 3 weeks of ...
Suppression of natural killer (NK) cell activity of spleen cells by thymocytes
(Elsevier, 1981-02)
The in vitro influence of thymus cells on natural killer cell activity of spleen cells against prelabeled target cells (YAC-I and RL[male symbol]I) has been studied in syngeneic as well as in allogeneic murine models. In ...
Fusion of mercury a new certified standard for differential scanning calorimetry
(Elsevier, 1990-03)
From the results of adiabatic-calorimetric measurements, mercury has been certified as a standard reference material for temperature and enthalpy of fusion for differential scanning calorimetry. The fusion temperature is ...
Development of crystalline inclusions (“ergosterol crystals”) in Neurospora crassa
(Springer-Verlag, 1976-09)
Development of crystalline inclusions (“ergosterol crystals”) in “snowflake”, a morphological mutant of Neurospora crassa has been examined. The inclusions which arise in membranebound organelles appear as electron dense ...
Effectiveness factor calculations for immobilized enzyme catalysts
(Wiley Subscription Services, Inc., A Wiley Company, 1973-09)
The steady state, nonlinear diffusion equations which describe reactions in constrained enzyme solutions are of great interest in many biological and engineering applications. As in other types of nonlinear differential ...
