This tremendous effort of the scientific community has confirmed the view that cancer actually represents a wide variety of diseases originating from different organs. selleck screening library These studies showed that TP53 and PI3KCA are the two most mutated genes in all types of cancers and that 30-70% of all solid tumors harbor

potentially ‘actionable’ mutations that can be exploited for patient stratification or treatment optimization. Translation of this huge oncogenomic data set to clinical application in personalized medicine programs is now the main challenge for the future. The gap between our basic knowledge and clinical application is still wide. Closing the gap will require translational personalized trials, which may initiate a radical change in our routine clinical practice in oncology.”
“Surgical Plethysmographic Index (SPI), calculated from pulse photo-plethysmographic amplitude oscillations, has been proposed as a tool to measure nociception anti-nociception balance during general anesthesia, but it is affected by several confounding factor that alter the autonomic nervous system (ANS) modulation. We hypothesized that SPI may be mainly affected by sympathetic stimulation independently from nociception. We studied the effects of two sympathetic stimuli on SPI, delivered

through passive head-up tilt at learn more 45 and 90 degrees angles, in nine awake healthy adults. The sympathetic modulation was assessed by means of heart rate variability (HRV) analysis. Mean (SD) SPI significantly increased from baseline to 45 degrees [from 38.6 (13.7) to 60.8 (7.6), p smaller than 0.001)] and to 90 degrees angle tilt [82.3 (5.4), p smaller than 0.001]. The electrocardiographic mean R-to-R interval significantly shortened during both passive tilts, whereas systolic arterial pressure did not change during the study protocol. HRV changed significantly during the study protocol towards a predominance of

sympathetic modulation during passive tilt. Gravitational sympathetic stimulation at two increasing angles, in absence of any painful stimuli, affects SPI in awake healthy volunteers. selleck products SPI seems to reflect the sympathetic outflow directed to peripheral vessels.”
“Histone-like proteins (such as HU, H-NS, and Fis) participate in nucleoid organization and in DNA replication, recombination, and transcription. Cold shock and anoxia upregulates a homologue of HU (Hlp) in Mycobacterium smegmatis, the nonpathogenic model of Mycobacterium tuberculosis. We show using electrophoretic mobility shift assays that Hlp, which in addition to the HU fold has a basic C-terminal tail containing multiple PAKK and PAAK repeats, has very high affinity for DNA. The affinity of Hlp for 76 bp linear DNA is higher, K(d) = 0.037 +/- 0.001 nM, compared to art Hlp variant without the C-terminal repeats, K(d) = 2.5 +/- 0.
