In this work, the sawmill waste from debarking was considered as source of valuable phytoconstituents. The extraction was performed using different ethanol/water mixtures, and characterization was obtained by LC-MS. This latter revealed flavonoid glycosides, lignans, and procyanidins.

Twenty BFDV strains isolated in Italy from juvenile Congo African grey parrots (Psittacus erithacus) were investigated. Seventeen strains showed an "atypical peracute form" (aPF) of the disease, and three a chronic form (CF).

The possible involvement of GABAergic B receptors in the control of LH and ACTH/cortisol secretion in response to naloxone was evaluated in seven normal men. Subjects were tested with naloxone (4 mg IV bolus plus 10 mg infused over 2 hr) with or without previous treatment with the gamma-aminobutyric acid (GABA)-ergic B receptor agonist, baclofen (5, 10 or 15 mg PO 30 min before naloxone). In additional experiments, six normal men were tested with 15 mg baclofen or placebo 30 min before a 2-hr infusion of normal saline.

Echocardiographic tracings of the septum, posterior wall and anterior mitral valve leaflet were analyzed by computer and compared with those of 25 age matched normal subjects (C). Acromegalic patients had a marked increase of the septum, posterior wall thickness and left ventricular muscular mass (p < 0.

The aim of this study was to compare the results obtained with those using standard precordial leads, in particular V4 and V6 leads. A group of 28 patients, males and females, aged between 15 and 55 years of age, was examined.
