A search for beta-lactamase in chlamydiae, mycoplasmas, planctomycetes, and cyanelles: bacteria and bacterial descendants at different phylogenetic p…

2000

Bacteria from different phylogenetic positions such as chlamydiae, mycoplasmas, planctomycetes and also endosymbiotic murein-containing cyanelles were investigated for the production of beta-lactamases. No beta-lactamase activity was found in bacteria lacking murein such as Chlamydia pneumoniae, Mycoplasma pneumoniae, Pirellula marina and Planctomyces maris. In the murein-containing cyanelles of Cyanophora paradoxa no beta-lactamase activity could be detected.

1649 Retrospective Analysis of Doxapram for the Treatment of Apnea of Prematurity

2012

Background and Aims Only one small randomized controlled study on doxapram to treat apnea of prematurity is available. Before the implementation of a local treatment protocol, we aimed to evaluate the frequency of administration of doxapram in our NICU. We asked, if frequency and severity of apneas were affected by doxapram, if intubation for apnea was avoided, and if side effects occurred. Methods We retrospectively analysed all premature infants Results 17 of 64 (27%) infants (mean gestational age 26.1 weeks, mean birth weight 733g) were treated during two years. All of them had been treated with caffeine before doxapram was applied. 70 therapy courses of 16 infants were analyzed. In 8 of…

Evidence for essential primary amino groups in a bacterial coupling factor F1ATPase.

1980

Abstract We have found that the binding of pyridoxal-5′-phosphate to 6 primary amino groups leads to the inactivation of the enzyme. A preferential reaction of pyridoxal-5′-phosphate with the α-subunits of this enzyme can be demonstrated. The reactivity of the amino groups is influenced by various effectors. In the presence of ATP the inhibition of the ATPase activity is noncompetitive.

A wide family of pyridoxal thiosemicarbazone ferric complexes: Syntheses, structures and magnetic properties

2009

Abstract This study reports the syntheses and the characterization of 12 ferric complexes of pyridoxal thiosemicarbazone. The richness of the coordination chemistry of this ligand is highlighted by the modulation of its charge from neutral H 2 L to anionic L 2− , thus leading to a wide family of ferric compounds with charge varying from +3 to −1. The structures of complexes [Fe(HL) 2 ]ClO 4  · 2H 2 O and [Fe(HL)L] · 4.5H 2 O were solved and discussed with a particular attention brought to the intermolecular interactions occurring between the complexes. The investigation of magnetic properties of these compounds revealed that two of them are in the HS state at any temperature, whereas the ot…

Elogio delle contaminazioni “disciplinari”

2021

Il saggio esprime i motivi di condivisione della linea editoriale della rivista, i tre punti cardine che definiscono il profilo teorico di Historia Magistra e che possono così essere riassunti: il fatto di considerare la storia “un diritto fondamentale di tutti gli esseri umani”, la dimensione scientifica dell’approccio storico (e della ricerca sociale in termini più ampi), la celebre frase di Marx per la quale la storia sarebbe “il faro che illumina ogni nostra conoscenza”. In questo caso, è utile rileggere l’affermazione marxiana dentro confini più ampi, sostituendo alla dimensione “disciplinare” (quella che vede, per l’appunto nella storia “una” specifica branca del sapere) la dimensione…

Giustificazione epistemica e responsabilità cognitiva nel Teeteto

2011

Sullo sfondo di un'interpretazione della critica al relativismo e allo scetticismo sofistico nel Teeteto che individua come suo esito la delineazione di un'epistemologia del dialeghesthai elenchico incentrata su una concezione fallibilista della verità come homologhia, il saggio cerca di mostrare come in questo dialogo platonico emerga il modello di un rapporto mente-mondo mediato concettualmente e razionalmente, diverso sia dal modello sofistico di conoscenza come passiva aisthesis, sia da quello di una pura conoscenza non contaminata dalla percezione che Platone sembrava voler sostenere con la Teoria dei due mondi. Una tale ipotesi di lettura è centrata sull'identificazione del nucleo più…

L'episteme e la sua giustificabilità razionale nella terza definizione del Teeteto: verso una teoria della responsabilità cognitiva

Treatment of pulmonary embolism.

2015

International audience; The treatment of pulmonary embolism is going to be deeply modified by the development of Direct Oral Anticoagulants (DOACs). There are currently three anti-Xa factors (rivaroxaban, apixaban, edoxaban) and one anti-IIa factor (dabigatran) labeled by the FDA and the EMA. All these drugs are direct anticoagulant, orally effective, without the need for adaptation to hemostasis test. As kidney excretion is involved for all of them, they are contra-indicated in patients with severe renal failure (creatinine clearance<30mL/min according to Cockcroft & Gault formula). All the anti-Xa factor drugs are metabolized by liver cytochromes and then contra-indicated in case of liver…

Pulmonary embolism hotline 2012. Recent and expected trials.

2012

SummaryManagement of acute pulmonary embolism (PE) has advanced considerably in the past year, and progress is expected to continue in 2013. To help determine the optimal management strategy for normotensive patients with intermediate-risk PE, the Pulmonary Embolism Thrombolysis (PEITHO) study completed enrolment of 1006 patients with evidence of right ventricular dysfunction (by echocardiography or computed tomography) plus a positive troponin test. Patients have been randomised to thrombolytic treatment with tenecteplase versus placebo, and the effects on clinical end points (death or haemodynamic collapse) assessed at 7 and 30 days. The results are expected in spring 2013; long-term foll…

Dental management of patients taking novel oral anticoagulants (NOAs): Dabigatran

2017

Background A new group of oral anticoagulants (dabigatran, rivaroxaban, apixaban and edoxaban) with clear advantages over classic dicoumarin oral anticoagulants (warfarin and acenocoumarol) has been developed in recent years. Patients being treated with oral anticoagulants are at higher risk for bleeding when undergoing dental treatments. Material and methods A literature search was conducted through April 2016 for publications in the ISI Web of Knowledge, PubMed and Cochrane Library using the keywords "dabigatran", "rivaroxaban", "apixaban", "edoxaban", "new oral anticoagulants", "novel oral anticoagulants", "bleeding" and "dental treatment". Results There is no need for regular coagulatio…
