Errores Médicos

open access: yesActa Médica Costarricense, 2008
En todas las actuaciones de los seres humanos, los errores son una realidad innegable. Por ser el ejercicio de la medicina algo que afecta directamente a las personas, este tema es uno de los más controvertidos, tanto en el nivel profesional como en los medios de comunicación, que siempre están ávidos de noticias impactantes y las destacan con ...

AAA+ protein unfoldases—the Moirai of the proteome

open access: yesFEBS Letters, EarlyView.
AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Quantifying the impact of energy system model resolution on siting, cost, reliability, and emissions for electricity generation

open access: yesEnvironmental Research: Energy
Runtime and memory requirements for typical formulations of energy system models increase non-linearly with resolution, computationally constraining large-scale models despite state-of-the-art solvers and hardware. This scaling paradigm requires omission

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

open access: yesMolecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.

L'error en els aparells com a possibilitat estètica

open access: yesArtnodes, 2012
L'error sembla que és el que s'interposa entre l'ésser ideal i el real. Un esdeveniment, un No-ésser que transforma i deforma l'Ésser. En les tècniques, tecnologies, suports i mitjans audiovisuals es mira de suprimir; tanmateix, hi ha una possibilitat ...

Concatenation of Error Avoiding with Error Correcting Quantum Codes for Correlated Noise Models

open access: yes, 2010
We study the performance of simple error correcting and error avoiding quantum codes together with their concatenation for correlated noise models. Specifically, we consider two error models: i) a bit-flip (phase-flip) noisy Markovian memory channel ...

Infrared laser sampling of low volumes combined with shotgun lipidomics reveals lipid markers in palatine tonsil carcinoma

open access: yesMolecular Oncology, EarlyView.
Nanosecond infrared laser (NIRL) low‐volume sampling combined with shotgun lipidomics uncovers distinct lipidome alterations in oropharyngeal squamous cell carcinoma (OPSCC) of the palatine tonsil. Several lipid species consistently differentiate tumor from healthy tissue, highlighting their potential as diagnostic markers.

PROCEDURE FOR QUANTITATIVE ESTIMATION OF CONFIRMATION OF THE PREDICTION BY THE STRUCTURAL 3D-MODEL FOR HORIZONTALSECTION OF WELLS

open access: yesИзвестия высших учебных заведений: Нефть и газ, 2016
This article considers the problems of estimation of the structural model verification based on the results of the well horizontal section drilling. The method of estimation by standard criteria of the structure confirmation is presented as well as the ...
