Bromo and extra terminal (BET) proteins (BRD2, BRD3, BRD4, BRDT) are transcriptional regulators required for efficient expression of several growth promoting antiapoptotic genes as well cell-cycle progression. BET recruited on transcriptionally active chromatin via their two N-terminal bromodomains (BRD), a protein interaction module that specifically recognizes acetylated lysine residues in histones H3 H4. Inhibition the BET-histone results downregulation number oncogenes, providing novel...

Sixty-five consecutive elderly patients (mean age 78 years) referred to a 'syncope' clinic over six-month period were prospectively studied. Initial evaluation included ambulatory electrocardiography, carotid sinus massage before and after atropine prolonged head-up tilt. Diagnostic criteria for causes of syncope assigned at the beginning study. Overall, diagnosis was attributed symptoms in 92% patients; overlap present quarter. Diagnoses cardioinhibitory syndrome (CSS; 5%), vasodepressor...

Abstract Background After the golden age of antibiotic discovery, bacterial infections still represent a major challenge for public health worldwide. The biofilm mode growth is mostly responsible chronic that current therapeutics fail to cure and it well-established novel strategies must be investigated. Particulate drug delivery systems are considered as promising strategy face issues related treatments in context. Particularly, poly-lactic acid (PLA) nanoparticles present great interest...

Paediatric B-precursor ALL is a highly curable disease, however, treatment resistance in some patients and the long-term toxic effects of current therapies pose need for more targeted therapeutic approaches. We addressed cytotoxic effect JQ1, selective inhibitor against transcriptional regulators, bromodomain extra-terminal (BET) family proteins, paediatric ALL. showed potent vitro response panel primary to independent their prognostic features but dependent on high MYC expression coupled...

To assess treatment with fludrocortisone in vasodepressor carotid sinus syndrome.Eleven patients, mean (SD) age 83 (5) years, daily dizzy episodes and a median of five (range two to 20) syncopal over one year were studied. All had syndrome (> 50 mm Hg fall systolic blood pressure during massage independent bradycardia). Carotid was carried out while the patient supine upright (tilt table) before after 600 micrograms intravenous atropine. Phasic heart rate recordings monitored throughout. The...

Poly(lactic acid) (PLA) nanoparticles (NPs) are widely investigated due to their bioresorbable, biocompatible and low immunogen properties. Interestingly, many recent studies show that they can be efficiently used as drug delivery systems or adjuvants enhance vaccine efficacy. Our work focuses on the molecular mechanisms involved during nanoprecipitation of PLA NPs from concentrated solutions lactic acid polymeric chains, specific interactions with biologically relevant molecules. In this...

Este artigo propõe-se a discutir ética na visão de Habermas. No trabalho, vamos explicar como Habermas constrói sua Ética do Discurso partir uma reformulação da Imperativo Categórico Kant. Isso porque, tal para Kant, também compreende que as normas morais devem ser passíveis universalização. entanto, o filósofo pragmatismo, essa universalização não é mais resultado reflexão monológica sujeito, mas discurso.
