Les sciences religieuses et la morphogenèse du sacré

(Résumé de l'ouvrage) Quest'opera intende riaprire un dibattito teorico sul ruolo della bellezza nella scienza, nell'arte e nella filosofia. I contributi qui raccolti esplorano i diversi modi attraverso i quali la bellezza, come elemento nel contempo estetico, empirico e concettuale, appare implicata nell'attività stessa di scoperta e di creazione. Pur nella loro diversità, tali approcci sono concordi nel sottolineare la necessità di rivalorizzare la ricchezza straordinaria e il carattere vivente delle ''bellezze'' del pianeta e della natura. In tale orizzonte, in cui quest'opera si colloca, appare fondamentale oltre che naturale il voler riconciliare scienza e filosofia, creatività matematica e immaginazione artistica, natura e cultura.

What is the presentation of renal angiomyolipomas?

Renal angiomyolipomas (AMLs) are commonly benign tumours formed by fat, blood vessels and non-striated muscle, which tend to be associated with neuroendocrine syndromes, or turn up sporadically.

Nephrocalcinosis in a patient with complete distal renal tubular acidosis.

A 35-year-old patient, diagnosed with distal renal tubular acidosis (dRTA), presented with metabolic acidosis (pH =7.1) together with hypokalaemia (2.8 meq/l), hyperlipidaemia and renal insuffi ciency (creatinine clearance = 60.8 ml/min). A 24 h urine examination showed an alkaline pH (7.5), hypercalciuria, hyperkaliuria hypocitraturia (1, 2 ,3). The patient was treated with potassium, citrate supplements and simvastatin . A typical renal colic occurred and an image study revealed considerable bilateral nephrocalcinosis, radio-opaque lithiasis in the left distal lumbar ureter and the right mid lumbar ureter with severe left ureter-hydronephrosis. Ureteroscopy and laser lithotripsy of left lumbar fragments were performed, continuing with the medical treatment (4).

Meta-analysis of studies analyzing the role of human papillomavirus in the development of bladder carcinoma

PURPOSE We aimed to ascertain the degree of association between bladder cancer and human papillomavirus (HPV) infection. MATERIALS AND METHODS We performed a meta-analysis of observational studies with cases and controls with publication dates up to January 2011. The PubMed electronic database was searched by using the key words "bladder cancer and virus." Twenty-one articles were selected that met the required methodological criteria. We implemented an internal quality control system to verify the selected search method. We analyzed the pooled effect of all the studies and also analyzed the techniques used as follows: 1) studies with DNA-based techniques, among which we found studies with polymerase chain reaction (PCR)-based techniques and 2) studies with non-PCR-based techniques, and studies with non-DNA-based techniques. RESULTS Taking into account the 21 studies that were included in the meta-analysis, we obtained a heterogeneity chi-squared value of Q(exp)=26.45 (p=0.383). The pooled odds ratio (OR) was 2.13 (95% confidence interval [CI], 1.54 to 2.95), which points to a significant effect between HPV and bladder cancer. Twenty studies assessed the presence of DNA. The overall effect showed a significant relationship between virus presence and bladder cancer, with a pooled OR of 2.19 (95% CI, 1.40 to 3.43). Of the other six studies, four examined the virus's capsid antigen and two detected antibodies in serum by Western blot. The estimated pooled OR in this group was 2.11 (95% CI, 1.27 to 3.51), which confirmed the relationship between the presence of virus and cancer. CONCLUSIONS The pooled OR value showed a moderate relationship between viral infection and bladder tumors.

Association of 25-hydroxyvitamin D with metabolic syndrome in patients with psoriasis: a case-control study.

Vitamin D deficiency is associated with higher cardiovascular risk and metabolic syndrome (MeS) criteria. The main objective of this study was to analyse the association of 25-hydroxyvitamin D (25-OHD) serum levels with MeS (National Cholesterol Education Program-Adult Treatment Panel-III criteria) in 46 Spanish patients with psoriasis, but without arthritis and systemic treatment, and 46 control subjects, matched by sex and age. The patients with psoriasis showed significantly lower level of 25-OHD than controls (30.5 vs. 38.3 ng/ml; p = 0.0001). Patients with MeS had significantly lower serum levels of 25-OHD than those without MeS (24.1 ± 7.5 vs. 32.8 ± 8.9, p = 0.007), and a negative correlation was found between 25-OHD and waist circumference, diastolic blood pressure, fasting glucose, and triglyceridaemia. In the control group no significant correlation between 25-OHD and MeS was found. Al-though the sample was small, our results suggest a potential protective role for 25-OHD in the metabolic profile of patients with psoriasis without arthritis.

Financiamento de parques tecnológicos: um estudo comparativo de casos brasileiros, portugueses e espanhóis

O mercado globalizado e de competição intensiva, no qual países e empresas estão inseridos, demanda uma busca constante por inovação. Entre os habitats de estímulo à inovação com diversas iniciativas pelo mundo, e também no Brasil, estão os chamados parques tecnológicos. Um dos grandes desafios para a implantação e a operacionalização desses empreendimentos é a obtenção de recursos. Surge, então, a questão: quais os mecanismos de financiamento de que a organização gestora de um parque tecnológico dispõe para realizar as fases de planejamento, implantação e operacionalização dos elementos constitutivos e serviços oferecidos por esse tipo de empreendimento? O objetivo neste trabalho é levantar e comparar os mecanismos de financiamento utilizados nas etapas citadas dos empreendimentos: Tecnopuc, Polo de Informática de São Leopoldo e Sapiens Parque, instalados no Brasil; Biocant Park e Taguspark, instalados em Portugal; Parque Tecnológico de Cartuja 93, Parque Tecnológico de Andalucia, Parque Científico de Barcelona, Parque Tecnológico de Bizkaia e Parque Tecnológico de Álava, instalados na Espanha. O que se pode observar em todos os casos estudados é que, mesmo apresentando organizações gestoras, atores e estruturas diferenciadas, o financiamento das fases de implantação não se deu somente por meio de recursos públicos ou privados, mas também por meio de parcerias. Além disso, verificou-se que as diferenças encontradas nos modelos de financiamento podem ser atribuídas, principalmente, a cinco fatores: participantes da organização gestora; modelo jurídico da organização gestora; elementos constitutivos de propriedade da organização gestora; atração de infraestruturas tecnológicas e empresas âncoras; disponibilidade de fundos públicos de fomento ao desenvolvimento tecnológico e econômico.

Evaluation of two HbA1c point-of-care analyzers.

BACKGROUND Measurement of HbA1c is the most important parameter to assess glycemic control in diabetic patients. Different point-of-care devices for HbA1c are available. The aim of this study was to evaluate two point-of-care testing (POCT) analyzers (DCA Vantage from Siemens and Afinion from Axis-Shield). We studied the bias and precision as well as interference from carbamylated hemoglobin. METHODS Bias of the POCT analyzers was obtained by measuring 53 blood samples from diabetic patients with a wide range of HbA1c, 4%-14% (20-130 mmol/mol), and comparing the results with those obtained by the laboratory method: HPLC HA 8160 Menarini. Precision was performed by 20 successive determinations of two samples with low 4.2% (22 mmol/mol) and high 9.5% (80 mmol/mol) HbA1c values. The possible interference from carbamylated hemoglobin was studied using 25 samples from patients with chronic renal failure. RESULTS The means of the differences between measurements performed by each POCT analyzer and the laboratory method (95% confidence interval) were: 0.28% (p<0.005) (0.10-0.44) for DCA and 0.27% (p<0.001) (0.19-0.35) for Afinion. Correlation coefficients were: r=0.973 for DCA, and r=0.991 for Afinion. The mean bias observed by using samples from chronic renal failure patients were 0.2 (range -0.4, 0.4) for DCA and 0.2 (-0.2, 0.5) for Afinion. Imprecision results were: CV=3.1% (high HbA1c) and 2.97% (low HbA1c) for DCA, CV=1.95% (high HbA1c) and 2.66% (low HbA1c) for Afinion. CONCLUSIONS Both POCT analyzers for HbA1c show good correlation with the laboratory method and acceptable precision.

Guidelines for the use and interpretation of assays for monitoring autophagy.

In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Accordingly, it is important to update these guidelines for monitoring autophagy in different organisms. Various reviews have described the range of assays that have been used for this purpose. Nevertheless, there continues to be confusion regarding acceptable methods to measure autophagy, especially in multicellular eukaryotes. A key point that needs to be emphasized is that there is a difference between measurements that monitor the numbers or volume of autophagic elements (e.g., autophagosomes or autolysosomes) at any stage of the autophagic process vs. those that measure flux through the autophagy pathway (i.e., the complete process); thus, a block in macroautophagy that results in autophagosome accumulation needs to be differentiated from stimuli that result in increased autophagic activity, defined as increased autophagy induction coupled with increased delivery to, and degradation within, lysosomes (in most higher eukaryotes and some protists such as Dictyostelium) or the vacuole (in plants and fungi). In other words, it is especially important that investigators new to the field understand that the appearance of more autophagosomes does not necessarily equate with more autophagy. In fact, in many cases, autophagosomes accumulate because of a block in trafficking to lysosomes without a concomitant change in autophagosome biogenesis, whereas an increase in autolysosomes may reflect a reduction in degradative activity. Here, we present a set of guidelines for the selection and interpretation of methods for use by investigators who aim to examine macroautophagy and related processes, as well as for reviewers who need to provide realistic and reasonable critiques of papers that are focused on these processes. These guidelines are not meant to be a formulaic set of rules, because the appropriate assays depend in part on the question being asked and the system being used. In addition, we emphasize that no individual assay is guaranteed to be the most appropriate one in every situation, and we strongly recommend the use of multiple assays to monitor autophagy. In these guidelines, we consider these various methods of assessing autophagy and what information can, or cannot, be obtained from them. Finally, by discussing the merits and limits of particular autophagy assays, we hope to encourage technical innovation in the field.
