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.

Article Synopsis
  • High-molecular risk (HMR) mutations, such as ASXL1 and IDH, are linked to poorer outcomes in myelofibrosis (MF) patients, particularly when combined with lower levels of the JAK2V617F variant allele frequency (VAF).
  • Analysis of 124 MF patients showed that HMR mutations significantly impacted prognosis for those with lower JAK2V617F VAF, while this effect was not observed in patients with higher VAF levels.
  • The study's findings indicate that having both HMR mutations and a lower JAK2V617F VAF (≤50%) serves as a strong independent risk factor for survival, improving existing prognostic models and prompting the need for further

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.

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.

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.

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.

  • Mutations in the TP53 gene, especially multihit alterations, are linked to worse clinical outcomes in patients with myelodysplastic syndrome (MDS).
  • This study analyzed TP53 abnormalities in 682 patients with MDS who had an isolated deletion of chromosome 5 (MDS-del(5q)), revealing that 24% had multihit mutations, indicating a greater risk for leukemic transformation.
  • The study found that the effect of monoallelic mutations varies with the variant allele frequency (VAF); lower VAF (<20%) behaved like wild-type TP53, while higher VAF (≥20%) showed outcomes similar to multihit mutations, highlighting the need for careful consideration of TP53 status in

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.

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.

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.

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.

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.

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.

Article Synopsis
  • In 2022, two new classification systems for myelodysplastic syndromes (MDS) were introduced: the International Consensus Classification (ICC) and the 2022 WHO classification, both aimed at improving disease categorization but differing in terminology and definitions.
  • A study validated these systems, showing they effectively help in distinguishing MDS types, highlighting that a blood blast percentage of ≥5% correlates with poorer survival rates and that specific mutations can provide insight on patient outcomes.
  • The research suggests that patients diagnosed with certain types of MDS show varying survival rates, and the proposal of an integrated classification system aims to enhance diagnosis and future MDS research, with further studies needed for verification.

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.
