Molecular Basis for Uracil‐DNA‐Glycosylase to Identify DNA Damage in the Nucleosome

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The DNA base‐excision repair (BER) pathway is initiated by a glycosylase, such as uracil‐DNA‐glycosylase (UDG), which identifies and removes a wrong base incorporated in the DNA sequence. The very early steps in the identification of the DNA damage are crucial to the correct initiation of the repair chain, and become even more complex when ...

Positive Matrix Factorisation (PMF) - An Introduction to the Chemometric Evaluation of Environmental Monitoring Data Using PMF [PDF]

, 2009
Positive Matrix Factorization (PMF) is a multivariate factor analysis technique used successfully among others at the US Environmental Protection Agency for the chemometric evaluation and modelling of environmental data sets. Compared to other methods it

A Rank‐Based CUSUM Monitoring Scheme for Time Between Events and Amplitude Data

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Monitoring time between events and amplitude (TBEA) data is critical in many applications, particularly in manufacturing, reliability engineering, and service operations. Yet, most existing TBEA control charts focus on a single quality characteristic and are typically developed under restrictive distributional assumptions.

Using MALDI‐FTICR Mass Spectrometry to Enhance ZooMS Identifications of Pleistocene Bone Fragments Showing Variable Collagen Preservation

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Recent advances in high‐throughput molecular analyses of collagen peptides, especially ZooMS (Zooarchaeology by Mass Spectrometry), have permitted breakthroughs in the analysis of archaeological material that is highly fragmented, a factor that hinders morphological identification.

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for

Programmable 3D Microfluidics Reveals Motility‐Driven Antibiotic Resistance Evolution in Gradients

Small, EarlyView.
Using a programmable microfluidic platform, this study shows that bacterial motility is crucial for resistance development in heterogeneous antibiotic landscapes. Motile Escherichia coli randomly migrates along antibiotic gradients, and sufficient movement is required for resistance to emerge.

Predictive Amphiphile Design Enables Control of Self‐Assembled Nanoparticle‐Cell Membrane Interactions

Small, EarlyView.
The interactions of self‐assembled nanocarriers with cell membranes are programmable through amphiphile design. We identify how head and tail chemistry govern distinct interaction mechanisms and introduce ΔGtransfer, a unified thermodynamic descriptor that predicts nanoparticle behaviour from simple molecular simulations.

Different inflammatory, fibrotic, and immunologic signatures between pre-fibrotic and overt primary myelofibrosis

Haematologica
Primary myelofibrosis (PMF) is a myeloid proliferative neoplasm (MPN) characterized by bone marrow (BM) fibrosis. Pre-fibrotic PMF (pre-PMF) progresses to overt PMF.

Thrombospondin-1 (TSP-1) in primary myelofibrosis (PMF) — a megakaryocyte-derived biomarker which largely discriminates PMF from essential thrombocythemia

, 2010
International audiencePrimary myelofibrosis (PMF) is a chronic myeloproliferative neoplasm showing aberrant bone marrow remodeling with increased angiogenesis, progressive matrix accumulation, and fibrosis development.
