A mutant ASXL1-BAP1-EHMT complex contributes to heterochromatin dysfunction in clonal hematopoiesis and chronic monomyelocytic leukemia.

is one of the three most frequently mutated genes in age-related clonal hematopoiesis (CH), alongside and (. CH can progress to myeloid malignancies including chronic monomyelocytic leukemia (CMML) and is also strongly associated with inflammatory cardiovascular disease and all-cause mortality in humans. DNMT3A and TET2 regulate DNA methylation and demethylation pathways, respectively, and loss-of-function mutations in these genes reduce DNA methylation in heterochromatin, allowing derepression of silenced elements in heterochromatin.

HOPX as a tumour-suppressive protein in T-cell acute lymphoblastic leukaemia.

The homeodomain protein homeobox (HOPX), a multifaceted regulator of cellular functions and developmental processes, is predominantly expressed in stem cells across diverse tissues; it has also emerged as a tumour suppressor in various solid cancers. However, its role in haematological malignancies still remains undefined. This study aimed to elucidate its significance in T-cell acute lymphoblastic leukaemia (T-ALL).

Acute Promyelocytic Leukemia Asian Consortium study of arsenic trioxide in newly-diagnosed patients: impact and outcome.

The Acute Promyelocytic Leukemia Asian Consortium analyzed a contemporaneous cohort of newly-diagnosed APL patients treated with and without frontline arsenic trioxide (ATO) in six centers. The objectives were to define the impact of ATO on early deaths and relapses, and its optimal positioning in the overall treatment strategy. In a 21.

Clinical relevance of NFYA splice variants in patients with acute myeloid leukaemia undergoing intensive chemotherapy.

Aberrant alternative splicing (AS) contributes to leukemogenesis, but reports on the clinical and biological implications of aberrant AS in acute myeloid leukaemia (AML) remain limited. Here, we used RNA-seq to analyse AS in AML cells from 341 patients, comparing them to healthy CD34 haematopoietic stem cells (HSCs). Our findings highlight distinct AS patterns in the nuclear transcription factor Y subunit alpha (NFYA) gene, with two main isoforms: NFYA-L (Long) and NFYA-S (Short), differing in exon 3 inclusion.

IDH2 mutation accelerates TPO-induced myelofibrosis with enhanced S100a8/a9 and NFκB signaling in vivo.

Introduction: mutation is an unfavorable prognostic factor in patients with primary myelofibrosis (PMF) but its effect on myelofibrosis (MF) remains largely unclear.

Methods: In this study, we aimed to elucidate the roles of mutation in the development and progression of MF by transcriptomic and molecular techniques using the transgenic mice.

Results: We found that thrombopoietin (TPO)-overexpressed ( + TPO) mice had accelerated progression to MF, compared with TPO-overexpressed wild (WT + TPO) mice, showing activation of multiple inflammatory pathways, among which nuclear factor κB (NFκB) was the most significantly enhanced.

STudy to ActivelY WARM trauma patients (STAY WARM): a pilot study assessing feasibility of self-warming blankets in patients requiring a massive hemorrhage protocol activation.

Purpose: Massively bleeding trauma patients often arrive to intensive care units hypothermic. Active warming blankets have shown promise in reducing hypothermia in the pre-hospital setting, but less is known about their in-hospital use. The aim of this pilot evaluation was to understand the feasibility of the Ready-Heat blanket in a level 1 trauma centre to improve the management of hypothermia in massively bleeding trauma patients.

Promising deep-red emitting Cr-doped SrAlO phosphors for plant growth LEDs.

Recently, deep-red-emitting phosphors that can be excited by ultraviolet (UV) and near-ultraviolet (NUV) light have been extensively investigated for plant growth LED applications. However, due to the harmful effects of these high-energy rays on plants, violet- or blue-excited deep-red-emitting phosphors are considered a more appropriate solution. In this work, SrAlO:Cr phosphors were synthesized using a simple solid-state reaction, revealing a strikingly sharp deep-red emission band centered at 694 nm and effective excitation by violet light.

Blood pressure screening results from May Measurement Month 2021 in Vietnam.

Elevated blood pressure (BP) is a growing burden worldwide, leading to over 10 million deaths each year. May Measurement Month (MMM) is a global initiative to raise awareness of high BP and acts as a temporary solution to the worldwide shortage of screening programmes. We aimed to screen for hypertension and cardiovascular risk factors in people aged ≥18 years in the community, thereby defining the proportion of participants with elevated BP and assessing the awareness and the effectiveness of its treatment.

Unraveling the role of hepatitis B virus DNA integration in B-cell lymphomagenesis.

Background: Studies have shown that hepatitis B virus (HBV)-associated B-cell non-Hodgkin lymphoma (NHL) constitutes a unique subgroup with distinct clinical features. It still leaves open the question of whether the integration of HBV DNA into the B-cell genome is a causal mechanism in the development of lymphoma.

Methods: Using the hybridisation capture-based next generation sequencing and RNA sequencing, we characterised the HBV integration pattern in 45 HBV-associated B-cell NHL tumour tissues.

Realization of a two-dimensional Weyl semimetal and topological Fermi strings.

A two-dimensional (2D) Weyl semimetal, akin to a spinful variant of graphene, represents a topological matter characterized by Weyl fermion-like quasiparticles in low dimensions. The spinful linear band structure in two dimensions gives rise to distinctive topological properties, accompanied by the emergence of Fermi string edge states. We report the experimental realization of a 2D Weyl semimetal, bismuthene monolayer grown on SnS(Se) substrates.

In vivo experimental study comparing alveolar ridge preservation versus guided bone regeneration after unassisted socket healing at intact and damaged sites in narrow alveolar ridges.

Background: To compare bone regeneration and dimensional alteration of alveolar ridge at intact and damaged extraction sockets after alveolar ridge preservation (ARP) and implant placement versus unassisted socket healing followed by guided bone regeneration (GBR) with simultaneous implant placement.

Methods: In 6 beagle dogs, 3 types of extraction sockets in the mandible were created: (1) intact sockets, (2) 1-wall defect sockets and (3) 2-wall defect sockets. The sockets were allocated to undergo either (1) ARP and implant placement 8 weeks later (ARP group) or (2) GBR with simultaneous implant placement after 8 weeks of unassisted socket healing (GBR group).

Association of Genotypes With Nasopharyngeal Carcinoma Risk.

Background/aim: The up-regulation of matrix metalloproteinase-9 (MMP-9) expression is a characteristic feature observed across various malignancies, including nasopharyngeal carcinoma (NPC). Nevertheless, the influence of MMP-9 genotype in the context of NPC remains underexplored. This study examined the implications of MMP-9 promoter rs3918242 genotypes on the susceptibility to NPC in Taiwan.

Evaluation of cutout factors with small and narrow fields using various dosimetry detectors in electron beam keloid radiotherapy.

Background: The inherent problems in the existence of electron equilibrium and steep dose fall-off pose difficulties for small- and narrow-field dosimetry.

Objective: To investigate the cutout factors for keloid electron radiotherapy using various dosimetry detectors for small and narrow fields.

Method: The measurements were performed in a solid water phantom with nine different cutout shapes.

Inequivalent and uncorrelated response priming in motor imagery and execution.

Introduction: Theoretical considerations on motor imagery and motor execution have long been dominated by the functional equivalence view. Previous empirical works comparing these two modes of actions, however, have largely relied on subjective judgments on the imagery process, which may be exposed to various biases. The current study aims to re-examine the commonality and distinguishable aspects of motor imagery and execution via a response repetition paradigm.

Multicolour and lineage-specific interphase chromosome Flow-FISH: method development and clinical validation.

Flow cytometry can be applied in the detection of fluorescence in situ hybridisation (FISH) signals to efficiently analyse chromosomal aberrations. However, such interphase chromosome (IC) Flow-FISH protocols are currently limited to detecting a single colour. Furthermore, combining IC Flow-FISH with conventional multicolour flow cytometry is difficult because the DNA-denaturation step in FISH assay also disrupts cellular integrity and protein structures, precluding subsequent antigen-antibody binding and hindering concurrent labeling of surface antigens and FISH signals.

Stellae-123 gene expression signature improved risk stratification in taiwanese acute myeloid leukemia patients.

The European Leukemia Net recommendations provide valuable guidance in treatment decisions of patients with acute myeloid leukemia (AML). However, the genetic complexity and heterogeneity of AML are not fully covered, notwithstanding that gene expression analysis is crucial in the risk stratification of AML. The Stellae-123 score, an AI-based model that captures gene expression patterns, has demonstrated robust survival predictions in AML patients across four western-population cohorts.

Kinome expression profiling improves risk stratification and therapeutic targeting in myelodysplastic syndromes.

The human kinome, which comprises >500 kinases, plays a critical role in regulating numerous essential cellular functions. Although the dysregulation of kinases has been observed in various human cancers, the characterization and clinical implications of kinase expressions in myelodysplastic syndromes (MDS) have not been systematically investigated. In this study, we evaluated the kinome expression profiles of 341 adult patients with primary MDS and identified 7 kinases (PTK7, KIT, MAST4, NTRK1, PAK6, CAMK1D, and PRKCZ) whose expression levels were highly predictive of compromised patient survival.
