Feasibility of Xenogeneic Mitochondrial Transplantation in Neuronal Systems: An Exploratory Study

open access: yesLife
Mitochondrial transplantation (MTx) has emerged as a potential therapeutic approach for diseases associated with mitochondrial dysfunction, yet its scalability and cross-species feasibility remain underexplored.

Bacterial Topography of the Healthy Human Lower Respiratory Tract

open access: yesmBio, 2017
Although culture-independent techniques have refuted lung sterility in health, controversy about contamination during bronchoscope passage through the upper respiratory tract (URT) has impeded research progress.

On critical semilinear elliptic systems

open access: yesAdvances in Differential Equations, 2001
The goal of the present paper is to study the existence of solutions of the semilinear elliptic system \[ \begin{gathered} -\Delta u+ u= |v|^{q-1} v+ g(x,v)\quad\text{in }\mathbb{R}^n,\\ -\Delta v+ v= |u|^{p-1} u+ f(x,u)\quad\text{in }\mathbb{R}^N,\\ u(x)\to 0\text{ and }v(x)\to 0\quad \text{as }|x|\to \infty,\end{gathered}\tag{1} \] where \({1\over p ...

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

open access: yesFEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Critical Theory -- An Alternative Solution to IT Planning Implementation Problems in Tourism [PDF]

open access: yes, 2004
Empirical evidence is presented, which suggests that current approaches to IT in tourism are dominated by the assumptions of the Postpositivist paradigm and are failing to meet the objectives they have set for themselves.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

On the Fault Hypothesis for a Safety-Critical Real-Time System

open access: yes, 2004
A safety-critical real-time computer system must provide its services with a dependability that is much better than the dependability of any one of its constituent components.

Critical incident monitoring in paediatric and adult critical care: from reporting to improved patient outcomes?

open access: yes, 2010
PURPOSE OF REVIEW: Critical incident reporting alone does not necessarily improve patient safety or even patient outcomes. Substantial improvement has been made by focusing on the further two steps of critical incident monitoring, that is, the analysis ...

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 ...
