on the relation between summation and facilitation.summation refers to the small reduction of threshold contrast as a signal is extended in space or time, or when multiple signals are presented simultaneously. facilitation refers to the large reduction in the threshold contrast increment when it is superimposed on a near-threshold pedestal contrast. separate hypotheses relate each of these effects to distinct measures of the log-log steepness of the psychometric function. this note shows that for 2-alternative forced-choice (2afc) proportion cor ...20133617542
[surgical case report: diagnosis of associated abdominal lesions in penetrating injuries of the lower chest].we discuss the way to diagnose intra-abdominal lesions caused by penetrating objects in the lower thorax. let us call these wounds penetrating wounds. two kinds of penetrating wounds are considered: 1. shotwounds; 2. knifewounds. 1. in shotwounds of the lower thorax there is not any non-surgical method available to find the associated intra-abdominal lesions. in these cases the results of: 1. physical examination; 2. local wound exploration; 3. echography of the abdomen and 4. peritoneal lavage ...20133661007

enhanced antiarrhythmic efficacy of propafenone when used in combination with procainamide or quinidine.this study evaluated the efficacy and safety of combining propafenone with procainamide or quinidine for treating ventricular arrhythmias in patients in whom procainamide or quinidine therapy alone failed to suppress arrhythmias. in 30 patients, the addition of propafenone resulted in a significant reduction of premature ventricular contraction (pvc) frequency compared to drug-free baseline (406 pvc/hr vs 33, p less than 0.001) and to procainamide or quinidine monotherapy (211 pvc/hr vs 27, p le ...20133630896
platelet mao activity in clinical subtypes of depression and dst suppression.platelet mao activity was measured in 75 hospitalized depressed patients and in 31 healthy subjects. plasmas post dexamethasone cortisol levels were examined in 73 patients. results indicate that higher platelet mao activity does not occur in all, but only in male major depressed patients. no relationship between changes of mao activity and specific clinical subtypes was found. platelet mao activity is not different between dst suppressors and dst non suppressors. the authors suggest that platel ...20133604729
studies on the interaction between antitrypanosome cis-ddp analogs with dna.the nature of the conformational changes produced in dna by cis-ddp analogs has been studied by physiochemical techniques. the uv spectra showed that the dna undergoes bathochromic shifts accompanied by hyperchromic effects in reaction with specific analogs (cis-pt(ddh) (mucobromic)2, cis-pt(tranilcypromine)2cl2 and cis-pt(ddh) cl2), while a different series of analogs (cis-pt(ddh) (metafluorobenzoic)2 and cis-pt(pentamidine)cl2) induce a significative decrease in the absorbance at 258 nm. moreo ...20133757148

[dorsal spondylodesis of the cervical spine using a hooked plate].the hook plate is a new device for achieving dorsal fusion of the lower cervical spine (c2-t1). using the dorsal approach, this technique guarantees independent stability that is sufficient even in cases without anterior stabilization. it satisfies the three main requirements for dorsal implants, i.e. a tension band, independent stability and the possibility of distraction. except in cases with direct anterior compression of the neural structures (such as herniated discs) the dorsal approach all ...20133574944
calcium in the mitochondria following brief ischemia of gerbil brain.calcium was localized in neurons and glial cells of the ca1 region of hippocampus and in neurons of parietal cortex with the oxalate-pyroantimonate electron cytochemical method following recovery from 5-min ischemia of gerbil brain. during the early postischemic recirculation phase a maximum amount of calcium deposits was detected in mitochondria of all investigated cells. a second rise in mitochondrial calcium deposits was observed in parallel with the onset of ultrastructural degeneration of m ...20133627566

the alprazolam to clonazepam switch for the treatment of panic disorder.forty-eight consecutive patients treated for panic disorder with alprazolam, but with presumed interdose anxiety symptoms, were switched to clonazepam. forty-one patients made the "switch" according to a protocol, and 82% rated clonazepam "better" because of decreased frequency of administration and lack of interdose anxiety. both medications seemed effective for panic disorder at comparable doses, and the authors describe how to switch from alprazolam to clonazepam when interdose anxiety is a c ...20133597803
[reconstructive plastic surgery of the humeral condyles following removal of endoprostheses of the elbow versus arthrodesis].the condyles of the elbow are of utmost importance for the stability of this joint. this is particularly evident in cases where elbow prostheses had to be removed because of loosening or infection and where the condyles had been deliberately resected at the primary operation. in order to obtain a functional elbow with sufficient stability and mobility after removal of the prostheses, we can reconstruct the condyles by means of a large autologous bone graft, which we take from the midpart of the ...20133658417
functional image data acquisition and processing.in the production of functional images certain hardware and software considerations are necessary for the rapid and accurate determination of kinetic parameters. the advent of the digital scintillation camera has made available increased accuracy of quantitation and ease of image handling, although its integrated computer system may not be optimal for program development presently. to reduce the deleterious effects of poisson noise on parameter estimation, the single or multiple application of e ...20133547664
clinical overview of alpha interferon. studies and future directions.the clinical development of the alpha interferons has now progressed through initial phase i and ii trials into extensive controlled clinical trial designs. alpha interferon has been a prototype of other biological agents that are now in clinical development. these agents operate through fundamentally different mechanisms of action than conventional chemotherapy and have produced a unique profile of side effects as well as response patterns. time to response is generally longer than with chemoth ...20133542185
[clinical incidence of subclavian thromboses following pacemaker implantation].although pacemaker (pm) implantation has developed into a standard therapy in appropriate rhythm disorders the procedure is not free of complications. one of the most common problems is thrombotic alteration in the region of the entry of the pacemaker electrode into the venous system. to obtain more details of the incidence and extent of these complications, we investigated a total of 97 patients in two groups, clinically, phlebographically and by doppler-ultrasound technique. 56 (30 males, 26 f ...20133538687
diabetes, noise exposure, and hearing loss.to examine the relationship of diabetes, noise exposure, and hearing loss, the authors reanalyzed data from a cross-sectional investigation on noise exposure, hearing loss, and bp conducted in a high-noise and a low-noise plant. twenty-eight of 348 participants met the following criteria for diabetes: (1) currently on insulin or oral hypoglycemics or (2) at least two elevated serum glucose levels despite adhering to a calorie-restricted diet. diabetics were evenly distributed between high- and l ...20133612333
