Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Philosophical, Physical and Media Electron [PDF]

open access: yesIn Medias Res, 2019
In the contemporary age of everincreasing influence of electronic media as much as on an individual psyche as on the society as a whole, it would be of great value to undertake a detailed analysis of the very foundation of that means of communication ...

Histiocitose de células de Langerhans: doença de Letterer-Siwe - importância do diagnóstico dermatológico em dois casos Langerhans cell histiocytosis: Letterer-Siwe disease - the importance of dermatological diagnosis in two cases

open access: yesAnais Brasileiros de Dermatologia, 2009
A histiocitose de células de Langerhans é proliferação clonal de células fenotipicamente semelhantes às células de Langerhans. Anteriormente denominada Letterer-Siwe, é a forma mais comum e mais grave dessa enfermidade, acometendo sobretudo crianças até ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Electron-Electron Interactions in Artificial Graphene

open access: yesPhysical Review Letters, 2012
Recent advances in the creation and modulation of graphene-like systems are introducing a science of "designer Dirac materials". In its original definition, artificial graphene is a man-made nanostructure that consists of identical potential wells (quantum dots) arranged in a adjustable honeycomb lattice in the two-dimensional electron gas.

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 ...

Electron Microscopy [PDF]

open access: yes, 2012
Correlative light (LM) and transmission electron microscopic (TEM) analysis is useful, if ultrastructural details of cells need to be related to functional aspects which can only be examined at the LM level. The first protocol presented here introduces a relatively simple way of obtaining TEM images which, on the one hand, reveal ultrastructural ...

Collision of a Positron with the Capture of an Electron from Lithium and the Effect of a Magnetic Field on the Particles Balance

open access: yesChemosensors, 2021
The processes of scattering slow positrons with the possible formation of positronium play an important role in the diagnosis of both composite materials, including semiconductor materials, and for the analysis of images obtained by positron tomography ...
