Conventional treatment lasts at least six months and has adverse effects; therefore, it is important to find therapeutic alternatives that reduce the bacterial load and may reduce the treatment duration. The immune response against tuberculosis can be modulated by several mechanisms, including extracellular vesicles (EVs), which are nano-sized membrane-bound structures that constitute an efficient communication mechanism among immune cells.Methods: The EVs released by the J774A.1 mouse macrophage cell line, both spontaneously (S-EV) and after infection with Mycobacterium tuberculosis H37Rv (Mtb-EV), were purified by ultra-centrifugation and size-exclusion chromatography. The size distribution and chemical composition of these EVs were evaluated, and their effect on the bacterial load and the production of cytokines was determined in both in vitro and in vivo models of M. tuberculosis infection.Results: Mtb-EV are larger than S-EV, they contain M. tuberculosis-specific antigens (not detected in EVs released from M. fortuitum-infected J774A.1 cells) and are rich in phosphatidylserine, present in their outer membrane layer. S-EV, but not Mtb-EV, reduced the bacterial load and the production of MCP-1 and TNF-α in M. tuberculosis-infected macrophages, and these effects were reversed when phosphatidylserine was blocked with annexin V. Both S-EV and Mtb-EV significantly reduced the lung bacterial load in mice infected with M. tuberculosis after 60 days of treatment, but they had no effect on survival or on the lung pneumonic area of these mice.Conclusion: J774A.1 macrophages infected with M. tuberculosis H37Rv released EVs that differed in size and phosphatidylserine content from spontaneously released EVs, and these EVs also had different biological effects: S-EV reduced the mycobacterial load and the cytokine production in vitro (through a phosphatidylserine-dependent mechanism), while both EVs reduced the lung bacterial load in vivo. These results are the basis for further experiments to evaluate whether EVs improve the efficiency of the conventional treatment for tuberculosis.Keywords: tuberculosis, extracellular vesicles, phosphatidylserine, macrophages, lung disease

One of the most important advances in this field has been due to pharmacological design of antibodies against immune checkpoint inhibitors. Anti-PD-1/PD-L1 antibodies are currently in advanced phases of clinical development for several tumors, including lung cancer. Results from Phase I–III trials with anti-PD-1/PD-L1 antibodies in non-small-cell lung cancer have demonstrated response rates of around 20% (range, 16%–50%). More importantly, responses are long-lasting (median duration of response, 18 months) and fast (50% of responses are detected at time of first tumor evaluation) with very low grade 3–4 toxicity (less than 5%). Recently, the anti-PD-1 antibody pembrolizumab received US Food and Drug Administration (FDA) breakthrough therapy designation for treatment of non-small-cell lung cancer, supported by data from a Phase Ib trial. Another anti-PD-1 antibody, nivolumab, has also been approved for lung cancer based on survival advantage demonstrated in recently released data from a Phase III trial in squamous cell lung cancer.Keywords: immunotherapy, immunoncology, cancer, checkpoint inhibitors

Abstract

Los analistas del presente están de acuerdo, en su gran mayoría, que la época moderna está terminando. Algunos hablan del fin de la historia, otros han bautizado este momento como postmodernismo, otros como el advenimiento del Apocalipsis Bíblico y otros preveen tragedias ecológicas a nivel planetario que extinguirán la vida. Cualquiera que sea la óptica con que se mire el fenómeno, en todas hay un denominador común: estamos a la puerta de un cambio de la magnitud de los anteriormente descritos. Sólo que va a ser en muy poco tiempo y el hombre educado con los paradigmas tradicionales no está preparado para enfrentarlo.

Abstract

Aims: The objective of the study is to determine the demographics and the in-hospital outcome of diabetic and non-diabetic patients treated with percutaneous coronary interventions (PCI) in Europe, to report the type of equipment and technology used for PCI procedures in diabetics and to clarify whether the treatment of diabetic patients complies with current European Society of Cardiology (ESC) guidelines. Methods and results: A total of 14,458 patients treated with PCI were enrolled from 29 member countries of the ESC between June 2005 and January 2006. Data were collected on patient characteristics and treatment, using new Cardiology Audit and Registration Data standards. In total, 3,603 patients (24.9%) were diabetic. Diabetics were older, more often female and had a higher body mass index than non-diabetics. Diabetics had higher rates of hypercholesterolaemia and hypertension, while current smokers were more frequent in the non-diabetics. Diabetics also had significantly higher rates of previous cardiovascular events. Clopidogrel was administered only in 48.1% of diabetic patients before PCI, while IIb/IIIa inhibitors were 22.9% during PCI. At discharge, there was a major adjustment of treatment with increases in the use of Beta-blocker (80.4%), angiotensin converting enzyme inhibitor (ACEI, 71.3%) and statins (89.8%) compared with on admission (Beta-blocker 60.9%, ACEI 55.0%, statin 63.1%). Inhospital mortality was higher in diabetics (1.8% vs 1.2%) although the in-hospital MACCE rate was not significantly different (3.6% vs 3.0%, p=0.09). Conclusions: Diabetic patients treated with PCI were older with more comorbidity. According to ESC guideline, the under-usage of clopidogrel, GP IIb/IIIa inhibitors should be improved. PCI is now taken as a good opportunity to adjust the use of appropriate medication. © Europa Edition. All rights reserved.

Abstract

Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p

Abstract

Aims: Revascularization in patients with coronary artery disease changed over the last two decades, favouring the number of patients treated by means of percutaneous coronary interventions (PCI) when compared with coronary artery bypass grafting (CABG). Many randomized controlled trials (RCTs) have been performed to compare these two competing revascularization techniques. Because of the strict enrolment criteria of RCTs in which highly selected patients are recruited, the applicability of the results may be limited in clinical practice. The current study evaluates to what extent patients in clinical practice were similar to those who participated in RCTs comparing PCI with CABG. Methods and results: Clinical characteristics and 1-year outcome of 4713 patients enrolled in the Euro Heart Survey on Coronary Revascularization were compared with 8647 patients who participated in 14 major RCTs, comparing PCI with CABG. In addition, we analysed which proportion of survey patients would have disqualified for trial participation (n = 3033, 64%), aiming at identifying differences between trial-eligible and trial-ineligible survey patients. In general, important differences were observed between trial participants and survey patients. Patients in clinical practice were older, more often had comorbid conditions, single-vessel disease, and left main stem stenosis when compared with trial participants. Almost identical differences were observed between trial-eligible and trial-ineligible survey patients. In clinical practice, PCI was the treatment of choice, even in patients who were trial-ineligible (46% PCI, 26% CABG, 28% medical). PCI remained the preferred treatment option in patients with multi-vessel disease (57% in trial-eligible and 40% in trial-ineligible patients, respectively, P < 0.001); yet, the risk profile of patients treated by PCI was better than that for patients treated either by CABG or by medical therapy. In the RCTs, there was no mortality difference between PCI and CABG. In clinical practice, however, we observed 1-year unadjusted survival benefit for PCI vs. CABG (2.9 vs. 5.4%, P < 0.001). Survival benefit was only observed in trial-ineligible patients (3.3 vs. 6.2%, P < 0.001). Conclusion: Many patients in clinical practice were not represented in RCTs. Moreover, only 36% of these patients were considered eligible for participating in a trial comparing PCI with CABG. We demonstrated that RCTs included younger patients with a better cardiovascular risk profile when compared with patients in everyday clinical practice. This study highlights the disparity between patients in clinical practice and patients in whom the studies that provide the evidence for treatment guidelines are performed. © The European Society of Cardiology 2006.

Abstract

Aim The objective behind the Euro Heart Survey on diabetes and the heart was to study the prevalence of abnormal glucose regulation in adult patients with coronary artery disease (CAD). Methods and results The survey engaged 110 centres in 25 countries recruiting 4196 patients referred to a cardiologist due to CAD out of whom 2107 were admitted on an acute basis and 2854 had an elective consultation. Patient data were collected via a web-based case record form. An oral glucose tolerance test (OGTT) was used for the characterisation of the glucose metabolism. Thirty-one per cent of the patients had diabetes. An OGTT was performed on the 1920 patients without known diabetes, of whom 923 had acute and 997 had a stable manifestation of CAD, respectively. In patients with acute CAD, 36% had impaired glucose regulation and 22% newly detected diabetes. In the stable group these proportions were 37% and 14%. Conclusion This survey demonstrates that normal glucose regulation is less common than abnormal glucose regulation in patients with CAD. OGTT easily discloses the glucometabolic state and should be a routine procedure. The knowledge of glucometabolic state among these patients should influence their future management because it has great potential to improve the outcome.

17. Influence of an external magnetic field in the two-photon absorption coefficient of magnetite nanoparticles in colloids and thin films

Author

Espinosa, D. H. G., Oliveira, C. L. P., and Figueiredo Neto, A. M.

Abstract

The Z-scan nonlinear optical and the small-angle x-ray scattering (SAXS) techniques are used to investigate the structure and nonlinear optical properties of magnetite nanoparticles dispersed in a colloid and trapped in thin films. The nonlinear refractive index (n_2) and the two-photon absorption coefficient (β) were measured as a function of the intensity of an external applied magnetic field H. Different relative orientations of the field with respect to the light polarization direction were investigated. When the external magnetic field is applied to the colloidal sample (H parallel to the light polarization direction), the two-photon absorption coefficient increases with the field, ranging from β=1.5  cm/GW (without field) to β=2.4  cm/GW (2700 Oe). For the field direction perpendicular to the light polarization direction, β decreases to β=1.0  cm/GW (2700 Oe) and after remains constant. These values evidence a two-photon absorption anisotropy in magnetite, and allowed us to evaluate some elements of the third-order nonlinear optical susceptibility tensor χ^(3). The SAXS experiments revealed that when the field is applied, small linear aggregates are formed in the direction of H.

Abstract

Toxoplasma gondii is an obligate intracellular parasite recognized as the etiological agent of Toxoplasmosis, a zoonotic disease endemic in different countries worldwide. In Mexico, the disease is recognized as a human and animal health problem. T. gondii sporozoites have the capacity of been released from the gut lumen and infect several tissues, including kidneys. Rodents have been identified as intermediate hosts of T. gondii; nevertheless, no previous reports exist in Yucatan, Mexico, about their role in the infectious cycle. A total of 187 specimens (130 Mus musculus and 57 Rattus rattus) were studied. Total DNA was extracted from renal tissue and was utilized in the identification of T. gondii with the end-point Polymerase Chain Reaction (PCR) method. Six positive products were purified and sequenced in order to confirm and validate the results through the BLAST Sequence Analysis Tool. The PCR provided a global positivity of 5.34% (10/187). The BLAST analysis found a direct homology for T. gondii with identities and coverage of 96-98% and 98-100%, respectively. Our results confirm the role of M. musculus and R. rattus in the biological cycle of T. gondii and offer knowledge of the parasite transmission in intermediary hosts of the region. Toxoplasma gondii est un parasite intracellulaire obligatoire et l'agent causal de la toxoplasmose, une zoonose endémique dans différents pays. Au Mexique, la maladie est reconnue comme un problème de santé humaine et animale. Les sporozoïtes de T. gondii peuvent être libérés de la lumière intestinale et infecter différents tissus, dont les reins. Bien que les rongeurs soient reconnus comme des hôtes intermédiaires de T. gondii, il n'existe aucune étude sur leur rôle dans le cycle d'infection dans la région du Yucatan au Mexique. Au total, 187 spécimens (130 Mus musculus et 57 Rattus rattus) ont été étudiés. L'ADN total a été extrait du tissu rénal et utilisé pour l'identification de T. gondii par PCR. Six amplicons ont été purifiés et séquencés afin de confirmer et valider les résultats en utilisant l'outil d'analyse de séquences BLAST. La PCR a donné une positivité globale de 5.34% (10/187). L'analyse BLAST a donné une homologie directe avec T. gondii, avec des identités et couvertures de 96-98% et 98-100%, respectivement. Nos résultats confirment le rôle de M. musculus et R. rattus dans le cycle biologique de T. gondii et apportent de la connaissance quant à la transmission du parasite dans des hôtes intermédiaires de la région.

Abstract

A new super-oxidized water (SOW) product, Microcyn, was tested for in vitro antimicrobial and antiviral activities. The effectiveness of this neutral-pH SOW at killing Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and Candida albicans in pure culture was evaluated. One millilitre (approximately 10(8)colony-forming units/mL) of each micro-organism was subjected to 9 mL Microcyn or sterile water at room temperature for 30s. Under these conditions, a log(10) reduction factor of 8 in the level of all pathogens occurred in the treatment samples. In addition, results of tests with three batches of Microcyn exposed to Bacillus atrophaeus spores for 5 min demonstrated complete inactivation of the spores within 2-3 min (log(10) reduction factor >4). The effectiveness of Microcyn in reducing human immunodeficiency virus-1 (HIV-1) on hard surfaces (glass) was also evaluated in compliance with Environmental Protection Agency requirements for virucidal claims. After exposure of the tested surfaces to Microcyn for 5 min without agitation, there was a log(10) reduction factor >3 in the viral load as measured by both cytopathic effect and antigen p24 of HIV-1 production in MT-2 cultures. Microcyn activity against adenoviral vector type 5 was also analysed under simulated laboratory in-use conditions with viral suspensions. In order to increase the sensitivity of the test, the fluorescent light emitted by AdGFP-infected cells was measured with the use of a flow cytometer. A log(10) reduction factor >3 in the viral load was achieved after a 5-min exposure to Microcyn under these strict conditions. These results show that Microcyn exerts a wide antimicrobial spectrum with major advantages over acidic SOWs, including neutral pH, lower free active chlorine (51-85 ppm) and long shelf life (1 year).

Abstract

Summary: A new super-oxidized water (SOW) product, Microcyn tm , was tested for in vitro antimicrobial and antiviral activities. The effectiveness of this neutral-pH SOW at killing Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and Candida albicans in pure culture was evaluated. One millilitre (∼108 colony-forming units/mL) of each micro-organism was subjected to 9mL Microcyn or sterile water at room temperature for 30s. Under these conditions, a log10 reduction factor of 8 in the level of all pathogens occurred in the treatment samples. In addition, results of tests with three batches of Microcyn exposed to Bacillus atrophaeus spores for 5min demonstrated complete inactivation of the spores within 2–3min (log10 reduction factor >4). The effectiveness of Microcyn in reducing human immunodeficiency virus-1 (HIV-1) on hard surfaces (glass) was also evaluated in compliance with Environmental Protection Agency requirements for virucidal claims. After exposure of the tested surfaces to Microcyn for 5min without agitation, there was a log10 reduction factor >3 in the viral load as measured by both cytopathic effect and antigen p24 of HIV-1 production in MT-2 cultures.

21. Study of the scale behaviour in the finishing mill to improve the strip surface quality*

Author

Espinosa, D., Lannoo, G., Malbrancke, J., Moreas, G., and Picard, M.

Abstract

The cracking behaviour of the oxide layer formed during hot rolling was studied together with different combinations of process parameters in order to find their single influence on the surface quality and formation of oxide defects. Several trials were performed on the CRM pilot line to study in detail the impact of strip reduction, strip temperature, entry scale thickness, roll degradation, lubrication, skin cooling, chemical composition and humidity on the scale behaviour. In general, the degree of deformation, entry scale thickness and rolling temperatures are the most important parameters and the importance decreases in that order.

23. Dexamethasone induces a heat‐stress response that ameliorates the conformational consequences on antithrombin of l‐asparaginase treatment

Author

HERNÁNDEZ‐ESPINOSA, D., MIÑANO, A., ORDÓÑEZ, A., MOTA, R., MARTÍNEZ‐MARTÍNEZ, I., VICENTE, V., and CORRAL, J.

Abstract

Background: l‐asparaginase (l‐ASP) treatment of patients with acute lymphoblastic leukemia causes a severe antithrombin deficiency by intracellular retention of this serpin within the endoplasmic reticulum (ER) of hepatic cells, and a subsequent risk of thrombosis. Interestingly, co‐administration of dexamethasone with l‐ASP seems to reduce the risk of thrombosis. Objectives:We have investigated the effect of two corticoids, dexamethasone and prednisone, on the conformational consequences of l‐ASP treatment on antithrombin. Patients/methods: Levels, activity, conformation and immunohistological features of antithrombin were studied in patients, cell and mice models. Because of the importance of the steroid receptor‐heat stress response (HSR) axis, and the role of unfolded protein response (UPR) in conformational diseases, we also evaluated Hsp27, Hsp70, Hsp90, HSF‐1 and ER chaperons (Grp78 and Grp94). Results:In all models, l‐ASP alone or in combination with prednisone caused the intracellular retention of antithrombin associated with a severe deficiency. In contrast, the combination of l‐ASP with dexamethasone ameliorated both the deficiency and intracellular retention of the serpin, which is associated with increased expression of heat shock proteins and ER‐chaperons. Conclusions:These results suggest a protective effect of dexamethasone on the conformational consequences of l‐ASP on antithrombin as a result of exacerbated HSR and UPR that help to explain the reduced risk of thrombosis reported in patients that follow this scheme of treatment.

24. In vivo effects of hyperthermia on the functional and conformational characteristics of antithrombin

Author

HERNÁNDEZ‐ESPINOSA, D., MOTA, R., MIÑANO, A., ORDÓÑEZ, A., YÉLAMOS, J., VICENTE, V., and CORRAL, J.

Abstract

Background: High temperatures produce in vitrotransitions of antithrombin to its inactive latent and polymeric forms. Accordingly, high body temperatures might contribute in vivoto conformational changes in antithrombin associated with increased thrombotic risk. Methods: We assessed the in vivoeffects of different hyperthermic stimuli on antithrombin. We studied two mouse models of hyperthermia. (i) Febrile syndrome induced by turpentine. (ii) Heat stroke generated by exposure to 42 °C. Body temperatures were measured. Antigen, anti‐factor Xa activity and conformational features of plasma antithrombin were studied. Furthermore, structural and ultrastructural features from livers were analyzed. Intracellular retention of serpins (antithrombin and α1‐antitrypsin) was studied by western‐blotting, immunohistochemistry, and immunogold‐labeling‐electron microscopy. Results: Hyperthermic stimuli caused a moderate deficiency of circulating antithrombin and a slight increase in its latent form. Moreover, hyperthermia caused intracellular retention of antithrombin into aggregates within the lumen of the endoplasmic reticulum of hepatocytes. This effect was similar for α1‐antitrypsin. Conclusion: Hyperthermia causes minor conformational changes on circulating antithrombin in vivo, although it has severe consequences for intracellular antithrombin and other hepatic serpins, inducing the intracellular retention of the nascent protein. These effects may contribute to the moderate plasma deficiency of antithrombin and the increased thrombotic risk detected in hyperthermic conditions.

27. Effects of Mo additions on the solidification of high chromium cast iron

Author

Tenório, J. A. S., Albertin, E., and Espinosa, D. C. R.

Abstract

High chromium white cast irons present high resistance to abrasive wear, being employed fundamentally in industrial branches that manipulate hard raw materials, such as the mining industry. Eutectic and hypoeutectic alloys containing increasing contents of molybdenum (0–2 wt%) were cast and used for the investigation of the effect of Mo and of the cooling rate on the coarsening of carbides. The experimental results were obtained by DTA experiments and by casting in special moulds specially designed to obtain directionally solidified columnar grains. Molybdenum additions results in increased eutectic cell diameter and increased carbide particle spacing. Molybdenum decreases both the austenite primary solidification temperature and the starting temperature for the univariant eutectic L → γ + M7C3, but the overall effect results in increased solidification intervals both in the austenite field and in the eutectic field.

29. Additivity of substituent effects in the fluoroarene series: Equilibrium acidity in the gas phase and deprotonation rates in ethereal solution

Author

Büker, H.H., Nibbering, N.M.M., Espinosa, D., Mongin, F., and Schlosser, Manfred

Abstract

Benzene and all mono-, di-, tri-, tetra- and pentafluoro substituted derivatives thereof were equilibrated with the corresponding aryl anions in the gas phase. Perfect additivity of the substituent effects on the acidity was observed. The basicities were diminished by 12, 6 and 4 kcal/mol depending on whether the supplementary fluorine atom occupied the ortho, metaor paraposition with respect to the deprotonation site. On the other hand, substituent effects on the rates of hydrogenmetalinterconversion processes level off with increasing numbers of halogens. For example, while the free energy of activation of sec-butyllithium promoted lithiation of fluorobenzene is at least 4 kcal/mol smaller than that of benzene, the difference was found to shrink to less than 2.5 kcal/mol when pentafluorobenzene and 1,2,3,4-tetrafluorobenzene were compared.
