ASC filament formation serves as a signal amplification mechanism for inflammasomes [PDF]

open access: yes, 2016
A hallmark of inflammasome activation is the ASC speck, a micrometre-sized structure formed by the inflammasome adaptor protein ASC (apoptosis-associated speck-like protein containing a CARD), which consists of a pyrin domain (PYD) and a caspase ...

Germline TP53 Mutations Causing Diamond–Blackfan Anemia: A French Report

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Diamond–Blackfan anemia is a rare congenital erythroblastopenia typically caused by mutations in ribosomal protein genes. Recently, gain‐of‐function mutations in TP53 have been identified as a novel cause of Diamond–Blackfan anemia. We report two French patients who both harbored a heterozygous TP53 deletion (NM_000546.5: c.1077delA; p ...

Formation mechanism of basalt-related agate deposits: an example from the Ating River alluvial gravels in the Xunke area, Heilongjiang, NE China

open access: yesFrontiers in Earth Science
This study investigates Xunke agates from Ating River alluvial gravels (Northeast, NE China) using optical microscopy, electron probe microanalyzer mapping (EPMA), and laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) to constrain ...

Characteristics and formation mechanism of talc in Permian Maokou Formation, southwestern Sichuan Basin: a case study of first member of Maokou Formation in well A1

open access: yesShiyou shiyan dizhi, 2021
Different forms of talc have been developed in the first member of Permian Maokou Formation (P2m1) in the Sichuan Basin. As a hydrothermal alteration mineral, its formation mechanism and its influence on the P2m1 reservoir need to be further explored ...

Surface chemistry in the Interstellar Medium II. $\mathrm{H}_2$ formation on dust with random temperature fluctuations

open access: yes, 2014
The $\mathrm{H}_2$ formation on grains is known to be sensitive to dust temperature, which is also known to fluctuate for small grain sizes due to photon absorption.

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.

Mechanism of membrane tube formation induced by adhesive nanocomponents

open access: yes, 2012
We report numerical simulations of membrane tubulation driven by large colloidal particles. Using Monte Carlo simulations we study how the process depends on particle size, concentration and binding strength, and present accurate free energy calculations

Two Faces of NOTCH1 in Childhood Lymphoblastic T‐Cell Neoplasia: Prognostic Divergence of Mutational and Structural Aberrations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT In pediatric patients, T‐cell lymphoblastic lymphoma (T‐LBL) survival exceeds 80%. Relapse remains associated with limited curative options. Frontline treatment is largely extrapolated from T‐cell acute lymphoblastic leukemia (T‐ALL) treatment, reflecting the ongoing debate, whether both entities represent distinct diseases or variants within ...

Genomic Insights Into Species Divergence and Adaptive Evolution in the Grass Genus Orinus on the Qinghai‐Tibet Plateau

open access: yesEcology and Evolution
The grass genus Orinus, endemic to the Qinghai‐Tibet Plateau (QTP), has long been taxonomically controversial. Recent integrative studies combining morphological and DNA barcoding proposed revising the genus from six to three species; however, this ...
