Low survival due to higher risk of relapse and non-relapse mortality after allogeneic HSCT in ATL compared with AML and ALL.

Background: Patients with adult T-cell leukemia/lymphoma (ATL) are considered to have worse outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT) than patients with other hematological malignancies, owing to high risk of relapse and immunocompromised status. However, no studies have compared transplant outcomes between patients with ATL and those with other hematological malignancies using a large-scale database.

Objectives: To compare transplant outcomes between patients with ATL and those with other leukemias and to identify factors contributing to worse transplant outcomes in ATL patients.

sp. nov., a crude oil aggregation-forming anaerobic bacterium isolated from marine sediment.

A crude oil aggregation-forming, strictly anaerobic, Gram-stain-positive, spore-forming, rod-shaped, motile and mesophilic bacterium, named strain SH18-2, was isolated from marine sediment near Sado Island in the Sea of Japan. The temperature, salinity and pH ranges of this strain for the growth were 15-40 °C (optimum 35 °C), 0.5-6.

Broad-spectrum efficacy of CEACAM6-targeted antibody-drug conjugate with BET protein degrader in colorectal, lung, and breast cancer mouse models.

Despite remarkable advances in cancer treatment, most solid cancers remain difficult to cure. We recently developed an antibody-drug conjugate (ADC, 84-EBET) for pancreatic cancer by using the carcinoembryonic-antigen-related cell-adhesion molecule 6 (CEACAM6) antibody #84.7 and the bromodomain and extra-terminal (BET) protein degrader EBET.

Effect of Epstein-Barr Virus infection on gene regulation in immune cells of patients with Immune-Mediated Diseases.

It has been known that Epstein-Barr virus (EBV) can latently infect immune cells after the initial infection, and epidemiological studies have suggested its association with the onset of immune-mediated diseases (IMDs). However, the specific impact of EBV infection on IMDs pathology remains unclear. We quantified EBV load of B cell subsets (Naïve B cells, Unswitched memory B cells, Switched memory B cells, Double negative B cells, and Plasmablasts) in IMD patients as well as healthy control (HC) using bulk RNA sequencing data of 504 donors.

AFM observation of protein translocation mediated by one unit of SecYEG-SecA complex.

Protein translocation across cellular membranes is an essential and nano-scale dynamic process. In the bacterial cytoplasmic membrane, the core proteins in this process are a membrane protein complex, SecYEG, corresponding to the eukaryotic Sec61 complex, and a cytoplasmic protein, SecA ATPase. Despite more than three decades of extensive research on Sec proteins, from genetic experiments to cutting-edge single-molecule analyses, no study has visually demonstrated protein translocation.

The impacts of alien species on river bioassessment.

The extent of alien taxa impacts on river ecosystem health is unclear, but their frequency continues to rise. We investigated 1) the prevalence of including alien taxa in common bioindicators used in river bioassessment, 2) the effect of alien taxa on the richness and abundance of natives, and 3) whether including alien taxa in bioassessment tools increased their sensitivity to river degradation. In the 17 countries analyzed fish represented the greatest number of alien species (1726), followed by macrophytes (925), macroinvertebrates (556), and diatoms (7).

In toto biological framework: Modeling interconnectedness during human development.

Recent advancements in pluripotent stem cell and synthetic tissue technology have brought significant breakthroughs in studying early embryonic development, particularly within the first trimester of development in humans. However, during fetal stage development, investigating further biological events represents a major challenge, partly due to the evolving complexity and continued interaction across multiple organ systems. To bridge this gap, we propose an "in toto" biological framework that leverages a triad of technologies: synthetic tissues, intravital microscopy, and computer vision to capture in vivo cellular morphodynamics, conceptualized as single-cell choreography.

Treatment Outcomes of Canine Orbital Meningiomas in Seven Cases.

Although intracranial and spinal cord meningioma prognoses have been reported, few studies have evaluated the outcomes and prognoses of orbital and optic nerve meningiomas in dogs. We aimed to evaluate the outcomes of canine orbital meningiomas. The seven dogs included were cytologically or histopathologically diagnosed with meningiomas.

Incidence of corneal perforation and lagophthalmos in patients with leprosy in Japan based on 40-year observations.

Purpose: This study aimed to report the incidence, characteristics, and prognosis of corneal perforation in patients with leprosy.

Study Design: Retrospective observational study.

Methods: Patients who presented with leprosy and visited a specialised ophthalmology hospital (Miyata Eye Hospital, Miyazaki, Japan) between 1980 and 2020 were included.

Cardiac Presynaptic Sympathetic Nervous Function Evaluated by Cardiac PET in Patients with Chronotropic Incompetence Without Heart Failure.

Chronotropic incompetence (CTI), the inability of the heart to increase its rate with increased activity, leads to exercise intolerance and predicts overall mortality. We previously reported that cardiac β-adrenergic receptor downregulation occurs in patients with CTI without heart failure (HF), indicating postsynaptic sympathetic nervous dysfunction. However, cardiac presynaptic sympathetic nervous system function in CTI is not fully understood.

Aberrant neuronal hyperactivation causes an age-dependent behavioral decline in .

Age-dependent sensory impairment, memory loss, and cognitive decline are generally attributed to neuron loss, synaptic dysfunction, and decreased neuronal activities over time. Concurrently, increased neuronal activity is reported in humans and other organisms during aging. However, it is unclear whether neuronal hyperactivity is the cause of cognitive impairment or a compensatory mechanism of circuit dysfunction.

TIM-3 marks measurable residual leukemic stem cells responsible for relapse after allogeneic stem cell transplantation.

In this study, we investigated the measurable residual leukemic stem cell (MR-LSC) population after allogeneic stem cell transplantation (allo-SCT) for high-risk acute myeloid leukemia (AML), utilizing T-cell immunoglobulin mucin-3 (TIM-3) expression as a functional marker of AML leukemic stem cells (LSCs). Analysis of the CD34CD38 fraction of bone marrow cells immediately after achievement of engraftment revealed the presence of both TIM-3LSCs and TIM-3 donor hematopoietic stem cells (HSCs) at varying ratios. Genetic analysis confirmed that TIM-3 cells harbored patient-specific mutations identical to those found in AML clones, whereas TIM-3 cells did not, indicating that TIM-3CD34CD38 cells represent residual AML LSCs.

WEE1 confers resistance to KRAS inhibitors in non-small cell lung cancer.

KRAS inhibitors sotorasib and adagrasib have been approved for the treatment of KRAS-mutant non-small cell lung cancer (NSCLC). However, the efficacy of single-agent treatments is limited, presumably due to multiple resistance mechanisms. To overcome these therapeutic limitations, combination strategies that potentiate the antitumor efficacy of KRAS inhibitors must be developed.

Globular-shaped Aβ oligomers have diverse mechanisms for promoting Aβ aggregations with the facilitation of fibril elongation.

The accumulation of amyloid β-proteins (Aβ) in the extracellular space, forming insoluble plaques, is a primary pathological process underlying Alzheimer's disease (AD). Among the various Aβ species that appear during Aβ aggregation, Aβ oligomers are considered the most neurotoxic form. However, the precise mechanisms of their molecular functions within the Aβ aggregation cascade have not been clarified so far.

All-Inside Arthroscopic Anatomic Anterior Talofibular Ligament Repair for Chronic Lateral Ankle Instability and Injury at the Talar Attachment: Surgical Technique.

Recently, arthroscopic anterior talofibular ligament (ATFL) repair has become popular, and favorable outcomes have been reported. In general, ATFL injuries are often caused by fibular attachment, and there are no reports of arthroscopic ligament repair of talar attachment injuries. We present a surgical technique for arthroscopic ligament repair via the anterolateral portal, accessory anterolateral portal, and far accessory anterolateral portal for ATFL injuries on the talar side.

The carbonyl nucleobase adduct MAde is a potent antigen for adaptive polyclonal MR1-restricted T cells.

The major histocompatibility complex (MHC) class I-related molecule MHC-class-I-related protein 1 (MR1) presents metabolites to distinct MR1-restricted T cell subsets, including mucosal-associated invariant T (MAIT) and MR1T cells. However, self-reactive MR1T cells and the nature of recognized antigens remain underexplored. Here, we report a cell endogenous carbonyl adduct of adenine (8-(9H-purin-6-yl)-2-oxa-8-azabicyclo[3.

Association between in-hospital weight change and 28-day mortality in adults with gram-negative rod bacteremia.

Background: Body weight and fluid balance are critical parameters in the monitoring of patient status, as low body weight and fluid overload are associated with increased mortality in sepsis cases. While body weight reflects nutritional and fluid status, fluid balance is a major indicator of clinical stability. However, limited research has comprehensively evaluated the combined impact of in-hospital weight change and fluid balance on mortality in bacteremia patients, especially those undergoing treatment outside of ICUs.

ML385, a selective inhibitor of Nrf2, demonstrates efficacy in the treatment of adult T-cell leukemia.

Nrf2 plays a critical role in regulating cytoprotective transcriptional responses and glucose metabolism while also preventing inflammation-induced carcinogenesis. However, Nrf2 can paradoxically promote carcinogenesis. Here, we aimed to elucidate the role of Nrf2 in ATL associated with HTLV-1.

Drug-induced liver injury related to avacopan therapy.

Objectives: The efficacy of avacopan as remission induction therapy for Anti-Neutrophil Cytoplasmic Autoantibody (ANCA)-associated vasculitis (AAV) is well-established. However, concerns regarding liver injury post-avacopan treatment remain, especially in Japan. Therefore, this study aimed to investigate drug-induced liver injury (DILI) associated with avacopan treatment.

Post-transplant transient abnormal myelopoiesis evolving from a GATA1 mutant clone in umbilical cord blood.

Transient abnormal myelopoiesis (TAM) generally affects newborns with Down syndrome and is associated with constitutional trisomy 21 and a somatic GATA1 mutation. Here we describe a case of TAM which evolved after umbilical cord blood transplantation (UCBT), whose origin was identified as a GATA1 mutation-harboring clone in umbilical cord blood (UCB) by detailed genetic analyses. A 58-year-old male who received UCBT for peripheral T-cell lymphoma presented progressive anemia and thrombocytopenia, and leukocytosis with blast cells in the peripheral blood (PB).

The importin α proteins IMPA1, IMPA2, and IMPA4 play redundant roles in suppressing autoimmunity in Arabidopsis thaliana.

Proteins in the importin α (IMPA) family play pivotal roles in intracellular nucleocytoplasmic transport. Arabidopsis thaliana possesses nine IMPA members, with diverse tissue-specific expression patterns. Among these nine IMPAs, IMPA1, IMPA2, and IMPA4 cluster together phylogenetically, suggesting potential functional redundancy.

Combined quantitative analysis of the nigro-striata system in multiple system atrophy and Parkinson's disease.

Degeneration of the nigrostriatal system occurs in multiple system atrophy (MSA) and Parkinson's disease (PD) via distinct pathological mechanisms. Here, we investigated nigrostriatal degeneration in MSA and PD by combining a newly developed method for evaluating the regional accumulation of dopamine transporter single-photon emission computed tomography (DAT SPECT) and individual voxel-based morphometry adjusting covariates (iVAC). We recruited 17 MSA patients and 13 PD patients, and compared their clinical and imaging indices.
