Megiston agathon (Pl. Ap. 38 a) – Sedno życia i filozoficznego wyzwania Sokratesa

We suggest a certain minimal approach to the historical Socrates on the basis of Plato’s Apology. This text makes it possible to reconstruct the authentic charge and the defense line of Socrates, as well as his motivation and the quintessence of his philosophical challenge. The most important thing is what the philosopher says in the face of his death sentence: that the greatest good for a man is to live an examined life focusing on virtues and ethical values. Unfortunately, the preponderance of studies, even the most recent ones, fail to recognize the philosopher’s provocative challenge, whilst it is not only a crucial motif in the Socratic examining (ἐξετάζειν), i.e. testing the interlocutors’ knowledge by means of irony, elenchos and aporia, but also an inspiration for his direct and indirect followers in seeking virtues and the greatest good.

Elafin prevents lipopolysaccharide-induced AP-1 and NF-kB activation via an effect on the ubiquitin-proteasome pathway

In this paper we follow on from our research into SLPI by assessing the immunomodulatory activity of elafin - an antiprotease related to SLPI and also present on the respiratory tract. We demonstrate for the first time that exogenously applied elafin inhibits lipopolysaccharide-induced activation of the NF-kappaB and AP-1 pathways in monocytes. I designed this project and supervised Marcus Butler during his MD thesis.

Ubiquitin-dependent proteolysis of trihydrophobin 1 (TH1) by the human papilloma virus E6-associated protein (E6-AP).

Human Papilloma virus E6-associated protein (E6-AP), which is known as an E3 ubiquitin ligase, mediates ubiquitination and subsequent degradation of a series of cellular proteins. In this paper, we identify here trihydrophobin 1 (TH1), an integral subunit of the human negative transcription elongation factor (NELF) complex, as a novel E6-AP interaction protein and a target of E6-AP-mediated degradation. Overexpression of E6-AP results in degradation of TH1 in a dose-dependent manner, whereas knock-down of endogenous E6-AP elevates the TH1 protein level. TH1 protein turnover is substantially faster, compared to controls, in cells that overexpressed E6-AP. Wild-type E6-AP promotes the ubiquitination of TH1, while a catalytically inactive point mutant of E6-AP abolishes its ubiquitination. Furthermore, in vitro ubiquitination assay also demonstrates that TH1 can be ubiquitinated by E6-AP. The degradation is blocked by treatment with proteasome inhibitor MG132. Herein, we provide strong evidence that TH1 is a specific substrate that is targeted for degradation through E6-AP-catalyzed polyubiquitination.

Genome-wide analysis of p63 binding sites identifies AP-2 factors as co-regulators of epidermal differentiation

The p63 transcription factor (TP63) is critical in development, growth and differentiation of stratifying epithelia. This is highlighted by the severity of congenital abnormalities caused by TP63 mutations in humans, the dramatic phenotypes in knockout mice and de-regulation of TP63 expression in neoplasia altering the tumour suppressive roles of the TP53 family. In order to define the normal role played by TP63 and provide the basis for better understanding how this network is perturbed in disease, we used chromatin immunoprecipitation combined with massively parallel sequencing (ChIP-seq) to identify >7500 high-confidence TP63-binding regions across the entire genome, in primary human neonatal foreskin keratinocytes (HFKs). Using integrative strategies, we demonstrate that only a subset of these sites are bound by TP53 in response to DNA damage. We identify a role for TP63 in transcriptional regulation of multiple genes genetically linked to cleft palate and identify AP-2alpha (TFAP2A) as a co-regulator of a subset of these genes. We further demonstrate that AP-2gamma (TFAP2C) can bind a subset of these regions and that acute depletion of either TFAP2A or TFAP2C alone is sufficient to reduce terminal differentiation of organotypic epidermal skin equivalents, indicating overlapping physiological functions with TP63.

O Tratamento dos activos fixos tangíveis no SNC proposto: sua comparação com o POC

Este artigo compara o Sistema de Normalização Contabilística (SNC) e o Plano Oficial de Contabilidade (POC), no que respeita ao reconhecimento, mensuração e divulgação dos activos fixos tangíveis. Para o efeito, analisou-se os dois normativos e procedeu-se à elaboração de quadros comparativos. Verificou-se que, de um modo geral, o SNC não se afasta muito do POC, pelo facto deste último nos últimos anos, ter sofrido várias influências anglo-saxónicas, e o SNC baseia-se nas normas internacionais de contabilidade adaptadas pela União Europeia. No entanto, trata-se de um sistema mais complexo do que o POC, contemplando numa só norma, todas as disposições gerais relativamente a esta matéria e remetendo para outras normas o tratamento de situações específicas.

Évaluation pré-clinique du (–)-[18F]FEOBV: Profil métabolique plasmatique.

Introduction. Plusieurs maladies neurodégénératives bénéficieraient de meilleures ap-proches diagnostiques, dont la maladie d’Alzheimer. Celle-ci affecte en particulier les systèmes cholinergiques du SNC, et de nombreuses études d’imagerie ont tenté d’évaluer la dégénérescence de ce système à des fins diagnostiques, à l’aide de ligands radioactifs de diverses composantes du système ACh. En définitive, la plupart de ces études ne se sont pas montrées satisfaisantes. À la recherche de meilleures approches dans ce domaine, nous avons décidé d’évaluer les possibilités offertes par le (-)-[18F]Fluoroethoxy-benzovesamicol ((-)-[18F]FEOBV), un agent émetteur de positons se liant au VAChT de façon spécifique et réversible. Avant d’en arriver à une utilisation humaine cependant, une validation animale en plusieurs étapes s’avère nécessaire, mais celle-ci nous est apparue justifiée à la lumière de résultats d’études préliminaires en TEP chez le rat, qui se sont montrées très prometteuses. Nous nous sommes donc attaqués à la caractérisation du métabolisme de cet agent. Ceci a exigé, dans un premier temps, la mise au point d’une méthode chromatographique d’analyse des métabolites sanguins et, dans un deuxième temps, l’évaluation de ces métabolites et de leur cinétique chez le rat. Ces données permettront ultérieurement, chez l’humain, de procéder à des études quantitatives en TEP. Étude #1: Une fois les paramètres chromatographiques optimisés, le TR du (–)-FEOBV fut établi à 7.92 ± 0.18 minutes. Étude #2 : Le métabolisme in vivo s’est montré très rapide et temporellement variable, mais un seul métabolite hydrophile a été identifié. La fonction d’apport au cerveau du (–)-[18F]FEOBV a pu être établie après correction pour la présence du métabolite détecté. Conclusion. Dans l’ensemble, le (–)-[18F]FEOBV semble très prometteur en tant que marqueur biologique du système cholinergique pré-synaptique.
