Acute and chronic hepatitis in childhood leukemia: a multicentric study from the Italian Pediatric Cooperative Group for Therapy of Acute Leukemia (A…

1985

The incidence of acute and chronic liver damage and its relation to hepatitis B virus (HBV) infection was evaluated in 164 consecutive children with acute leukemia seen in ten Italian hemato-pediatric units. Thirteen out of 164 children (7.9%) had acute hepatitis (AH) during treatment, while 8/90 (8.8%) showed an acute exacerbation of liver damage within 6 months after therapy withdrawal. Seven of the 13 children with AH while on therapy were HBsAg positive. In 12/13 cases, liver disease progressed to chronicity. Five of eight children who developed AH after completion of treatment were HBsAg positive. Eighty-nine patients (54.2%) developed biochemical evidence of chronic hepatitis during t…

Tool Failure in Sequential Cutting of two Different Materials

1985

In this paper the authors show that the premature tool breakage, characteristic of interrupted cutting, can be enhanced in sequential cutting of two materials having different mechanical and chemical properties. The results of experimental investigations carried out in turning pieces consisting of medium carbon steel and aluminium alloy show that the time to failure is significatively lower than that occurring in machining only one of the two materials; moreover the morphology of the damage depends by the cutting order. Working with the sequence steel-Al alloy welding phenomena caused by strong deoxidation due to the latter material are observed; these phenomena cause the early development …

Acute toxicity of some chlorinated phenolic compounds toSelenastrum capricornutum and phytoplankton

1985

Acute toxicity of several chlorinated phenolic compounds detected in waste waters of bleached pulp was determined forSelenastrum capricornutum and indigenous phytoplankton using bioassays. Five of the phenolic compounds were chlorocatechols, four were chloroguaiacols and one was chlorosyringol. The response ofSelenastrum capricornutum to chemicals was measured by cell counting and phytoplankton14C-uptake. Chlorinated catechols inhibited the growth ofSelenastrum cultures in lower concentrations than chlorinated guaiacols. The increasing number of chlorine substituents on the phenolic ring increased the toxicity of both chlorinated catechols and guaiacols. The EC50-values (0-96 hr) of the com…

Studies on zymogenicity and solubilization of chitin synthase from Candida albicans

1985

The zymogenic form of the chitin synthase present in mixed membrane preparations was extracted by digitonin treatment. The residual extracted membranes exclusively retained the basal activity. Trypsin activation of the zymogenic form of the enzyme did not modify the digitonin solubilization characteristics of the original zymogenic form, suggesting significant differences between ‘in vivo’ activation of chitin synthase and that carried out by trypsin ‘in vitro’.

On the Influence of the Radius Between Face and Flank on the Tool Life of Sintered Carbides

1985

Experimental investigations carried out by the authors in interrupted cutting, show that if the cutting edge survives to few impacts, then fracture will take place to very high number of impacts. Early fractures can be explained by assuming the presence of microscopic defects on the tool edge; a longer life can be referred to an increase tool strengthness due to rounding of the edge as a consequence of the wear process. In order to study the effects of the rounding of the edge, experimental tests have been carried out on several inserts of sintered carbides with different values of the radius of the edge between face and flank obtained by a tumbling process. The results show that the greate…

Structurally Uniform Oligomers

1985

Model compounds as well as prototype reactions are frequently used to understand more complex chemical systems. In the case of phenolic resins a large number of model compounds have been synthesized. They are regarded as either components of a complex mixture of novolaks or resoles or as representative segments of the phenolic crosslinked network. These model compounds were formerly the basis for the correlation of physical properties to molecular structure. Presently the progress of analytical separations and identification methods is formidable; highly sophisticated chemical instrumentation allows the analysis of highly complex mixtures. Nevertheless, well defined compounds with definite …

1985

The virulence of bacteria in many phagocytic systems has been studied for several years and it is known that macrophages play an important role in host defence against invading microorganisms and in cooperation with cellular and humoral immune mechanisms. Pathogenic bacteria can be divided into two groups with regard to their fate within phagocytes: (a) extracellular bacteria which are promptly killed after phagocytosis and (b) facultative intracellular bacteria which are resistant to intracellular killing unless macrophages are activated. Humoral immune mechanisms (antibody, complement) deal mainly with extracellular bacteria, while cellular immune mechanisms (T cells, macrophages) deal wi…

Medical Attendance in Air Transportation of Patients

1985

SummaryAir transportation missions of seriously ill or injured patients are subdivided into rescue missions and medical evacuation missions. In 1981, for rescue missions, 29 stationed rescue helicopters were available with an operation radius of 50 km. Their task consisted of securing the primary care for vital risk patients as soon as possible. Medical evacuation missions were realized by helicopter, ambulance aircraft, and airliner. Before take-off a medical briefing was held to diminish the transport-trauma. Patients with cardiopulmonary insufficiency are at risk as simultaneous appearance of acceleration, climbing rate, falling cabin pressure and emotional stress may produce serious com…

The X-ray gas scintillation spectrometer experiment on the first spacelab flight

1985

The First Spacelab mission, launched on Space ShuttleFlight STS-9 in November 1983 carried a multidisciplinary payload which was intended to demonstrate that valuable scientific results can be achieved from such short duration missions. The payload complement included a spectrometer to undertake observations of the brighter cosmic X-ray sources. The primary scientific objectives of this experiment were the study of detailed spectral features in cosmic X-ray sources and their associated temporal variations over a wide energy range from about 2 up to 30 keV. The instrument based on the gas scintillation proportional counter had an effective area of some 180 cm2 with an energy resolution of ∼9…

Medullary respiratory-related neurons with axonal connections to rostral pons and their function in termination of inspiration.

1985

In urethane-anaesthetized, paralyzed and artificially ventilated rabbits, medullary respiration-related neurons (RRU) were classified according to the phase relation of their burst discharge to phrenic nerve activity. Phase-bound inspiratory (I) or expiratory (E) neurons were discriminated from phase-spanning expiratory-inspiratory (EI) or inspiratory-expiratory (IE) units. Mechanisms of termination of inspiration by electrical stimulation of rostral pontine nuclei (Nc. parabrachialis medialis; Lc. coeruleus) were examined firstly to demonstrate whether RRU receive descending excitatory and inhibitory afferents as well as ascending efferents and secondly to analyse the time course of the ne…

La geografía en la E. G. B: Un ejemplo de descoordinación entre programas renovados y libros de texto

1985

Este trabajo explica el sentido que ha de tener la Geografía en la E.G.B. y los contenidos a estudiar según los Programas Renovados, por un lado; y el enfoque y contenidos de la Geografía que hay que estudiar según los libros de texto, por otro. A través del análisis de las distintas capacidades y contenidos que se plantean, se observa: 1.º Que la Geografía presentada por los Programas Renovados no se adapta plenamente a las exigencias de la sociedad y realizadas actuales; 2.º Que existe una descoordinación entre Programas Renovados y libros de texto; 3.º Que los libros de texto no trabajan aquellos objetivos para los que sus autores afirman que han sido editados. Por tanto, podremos utiliz…

The effects of prostaglandin F2α in the human eye

1985

The ocular effects of 200 micrograms of topically applied prostaglandin F2 alpha were studied in 18 nonglaucomatous volunteers. A fall in intraocular pressure was seen in the prostaglandin-treated eyes when compared with the placebo-treated control eyes. The maximum intraocular pressure reduction was observed at the 7th h and hypotensive ocular effect persisted for 24 h. Prostaglandins did not produce any change in pupillary diameter or signs of intraocular inflammation visible by anterior segment biomicroscopy or iris fluorescein angiography. The drug caused side effects: conjunctival hyperemia was constant and many patients complained of ocular smarting and headache. It could be useful in…

In the present study, the investigation of social attitudes has been operationalized by studying the control directed by Finnish society towards one of its marginal groups, the vagrants, in the beginning of the 19th century. As vagrancy had not in fact been officed by legislation as a crime but as its consequences (deprivation of freedom) were much the same as those of actual criminality, 1t 1s Justifiable also from the point of view of the legal protection of the contemporary individual, to look into the question of how the decision of depriving a person of his freedom was reached. Because vagrancy, according to the existing servant and recruiting regulations, reformed in the beginning of …

Quantum and Classical Statistical Mechanics of the Non-Linear Schrödinger, Sinh-Gordon and Sine-Gordon Equations

1985

We are going to describe our work on the quantum and classical statistical mechanics of some exactly integrable non-linear one dimensional systems. The simplest is the non-linear Schrodinger equation (NLS) $$i{\psi _t} = - {\psi _{XX}} + 2c{\psi ^ + }\psi \psi $$ (1) where c, the coupling constant, is positive. The others are the sine- and sinh-Gordon equations (sG and shG) $${\phi _{xx}} - {\phi _{tt}} = {m^2}\sin \phi $$ (1.2) $${\phi _{xx}} - {\phi _{tt}} = {m^2}\sinh \phi $$ (1.3)
