ASCA PV observations of the Seyfert 1 galaxy MCG63015 : rapid variability of the warm absorber. ABSTRACT We present a detailed re-analysis of the two ASCA Performance Veriication observations of the nearby Seyfert 1 galaxy MCG63015. Connrming the results of Fabian et al. (1994), we nd deenite evidence for the O vii and O viii K-shell absorption edges of the warm absorber and a doubling of the w...

BACKGROUND The addition of triiodothyronine (T(3)) is one of the most widely studied augmentation strategies for refractory depression. Despite this there are no long term studies or studies of doses above 100 mcg. METHOD Long term and high dose augmentation with T(3) for refractory unipolar major depression was studied. Seventeen patients were assessed for symptom improvement with the Clinic...

In shallow lakes, different primary producers might impact the physiochemical characteristics of the sediment and the associated microbial communities. Until now, little was known about the features of sediment Archaea and their variation across different primary producer-dominated ecosystems. Lake Taihu provides a suitable study area with cyanobacteria- and macrophyte-dominated zones co-occurr...

At intravenous dosages of ≥8 mcg/kg, sufentanil produces hypnosis and anesthesia without the use of additional anesthetic agents. A deep level of anesthesia is maintained at these dosages, as demonstrated by EEG patterns. Dosages of up to 25 mcg/kg attenuate the sympathetic response to surgical stress. The catecholamine response, particularly norepinephrine, is further attenuated at doses of su...

Background: Opioids added to local anesthetics for peripheral nerve blocks may intensify analgesia and prolong analgesic and sensorial block duration. These agents may also cause potentiation and prolongation of motor block. Objective: This study compared the postoperative effects of 30 mL of 0.25% bupivacaine +50 mcg fentanyl and 30 mL of 0.25% bupivaca...

Magnetocardiography (MCG) is the recording of the magnetic field (MF) generated by cardiac electrophysiological activity. Because it is a contactless method, MCG is ideal for noninvasive cardiac mapping of small experimental animals. The aim of this study was to assess age-related changes of cardiac intervals and ventricular repolarization (VR) maps in intact rats by means of MCG mapping. Twent...

Identifying species or individuals that feed upon other species of animals is an important aspect of some predation studies. We evaluated the effectiveness with which the biomark associated with iophenoxic acid (IA) injections was transferred from domestic goats to coyotes (Canis latrans) that fed on them. We injected doses of 100, 300, or 1,000 mg of IA into goats to raise serum iodine levels,...

Magnetocardiogram (MCG) mapping is a new promising non-invasive tool for obtaining functional information concerning the electrical activities of the heart. Since MCG was first measured by Baule and McFee[1], the MCG has been studied worldwide. In particular, it is known that Cohen and his co-workers measured the MCG by use of a SQUID inside a magnetically shielded room[2] and the technique has...

Magnetocardiographic (MCG) mapping measures magnetic fields generated by the electrophysiological activity of the heart. Quantitative analysis of MCG ventricular repolarization (VR) parameters may be useful to detect myocardial ischemia in patients with apparently normal ECG. However, manual calculation of MCG VR is time consuming and can be dependent on the examiner’s experience. Alternatively...
