The peripheral artery disease is frequent among patients undergoing hemodialysis much more than in the general population. The ankle-brachial index (AB!) is a potent tool to screen this pathology. We analysed the relationship between ABI abnormal values and arteriovenous fistulas (AVF) complications such as stenosis and thrombosis among chronically hemodialysis pat ients (HD). [less ▲]

Regarding the high prevalence of African American patients with ESRD, it is important to estimate the prevalence of early stages of chronic kidney disease in this specific population. Because serum creatinine concentration is dependent on muscular mass, an ethnic factor has to be applied to creatinine-based equations. Such ethnic factors have been proposed in the Modification of Diet in Renal Disease (MDRD) study equation and in the more recent Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. This review analyzes how these correction factors have been developed and how they have, or have not, been validated in external populations. It will be demonstrated that the African American factor in the MDRD study equation is accurate in African American chronic kidney disease (CKD) patients. However, it will be shown that this factor is probably too high for subjects with a GFR of >60 ml/min per 1.73 m2, leading to an underestimation of the prevalence of CKD in the global African American population. It will also be confirmed that this ethnic factor is not accurate in African (non-American) subjects. Lastly, the lack of true external validation of the new CKD-EPI equations will be discussed. Additional trials seem necessary in American African and African populations to better estimate GFR and apprehend the true prevalence of CKD in this population with a high renal risk. [less ▲]

Various peptide segments have been modeled as asymmetric amphipathic alpha-helices. Theoretical calculations have shown that they insert obliquely into model membranes. They have been named "tilted peptides". Molecular modeling results reported here also evidence the presence of tilted peptides in ADM-1 protein of Caenorhabditis elegans that may be involved in fusion events, in meltrin alpha, a protein implicated in myoblast fusion, in hemagglutinin of influenza virus, in the E2 glycoprotein of rubella virus, in the S protein of hepatitis B virus, in a subdomain of Ebola virus and in the malaria CS protein. Experimental results have indicated that tilted peptide fragments may be involved in cellular life events like sperm-egg fecondation, muscle development, protein translocation through signal sequences and cellular death caused by viral infection or parasite infestation. We speculate that membrane destabilization by these tilted peptides may be an important common step in life processes involving fusion phenomena. [less ▲]

The IKKs, IKKa and IKKb, and the IKK-related kinases TBK1 and IKKe, play essential roles in innate immunity through signal-induced activation of NF-κB and IRF3/7, respectively. Although the signaling events within these pathways have been extensively studied, the mechanisms of IKK and IKK-related complex assembly and activation remain poorly defined. Recent data provide insight into the requirement for scaffold proteins in complex assembly; NEMO coordinates some IKK complexes, whereas TANK, NAP1 or SINTBAD assemble TBK1 and IKKe complexes. The different scaffold proteins undergo similar post-translational modifications, including phosphorylation and non-degradative polyubiquitylation. Moreover, increasing evidence suggests that distinct scaffold proteins assemble IKK and potentially TBK1 and IKKε sub-complexes in a stimulus-specific manner, which might be a mechanism to achieve specificity.

A recent photometric survey in the NGC 3766 cluster led to the detection of stars presenting an unexpected variability. They lie in a region of the Hertzsprung-Russell (HR) diagram where no pulsation are theoretically expected, in between the δ Scuti and slowly pulsating B (SPB) star instability domains. Their variability periods, between ~0.1-0.7 d, are outside the expected domains of these well-known pulsators. The NCG 3766 cluster is known to host fast rotating stars. Rotation can significantly affect the pulsation properties of stars and alter their apparent luminosity through gravity darkening. Therefore we inspect if the new variable stars could correspond to fast rotating SPB stars. We carry out instability and visibility analysis of SPB pulsation modes within the frame of the traditional approximation. The effects of gravity darkening on typical SPB models are next studied. We find that at the red border of the SPB instability strip, prograde sectoral (PS) modes are preferentially excited, with periods shifted in the 0.2-0.5 d range due to the Coriolis effect. These modes are best seen when the star is seen equator-on. For such inclinations, low-mass SPB models can appear fainter due to gravity darkening and as if they were located between the δ Scuti and SPB instability strips. [less ▲]

Background : The aims of this study were to evaluate the effect of a single PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies, but otherwise healthy, and to determine the biomarkers that constitute good prognosis factors, if any. Methods : 48 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a single PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterolemia,...) were measured. A pain assessment was then made using a Visual Analog Scale of pain (VAS) and a pressure algometer. The same assessment was carried out after 6 weeks and 12 weeks when possible. Results : There is an overall significant improvement in VAS score at the end of the 12 weeks follow- up. However, no correlation was found between the evolution of the clinical scores and the biological parameters measured. Conclusion: A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathies who were refractory to conventional physio- therapy, whatever the initial values of the measuured biological parameters.

Bernard Bolzano notoriously rejected Immanuel Kant’s claim that arithmetic and geometry were grounded on synthetic a priori judgements based on pure intuition. According to Bolzano, only analysis of concepts could ground the generality of mathematical statements and proofs; such a stand would later lead to logicism (from Frege to Carnap). Far from going in this way, however, Charles Sanders Peirce, who was one of the fathers of formal logic but also a great admirer of Kant, provided semiotic reasons to believe that diagrams do have a general meaning and that they can provide a knowledge which is both general and “ampliative”. Unlike mere logical analysis, diagrams (the analogon of Kant’s schemas) help to explore concepts by going somehow “outside of them” in such a way that new knowledge is gained. This provides new support to Kant’s notion of intuitive construction, which is supposed to be both deductive and inventive [less ▲]
