Thermoelectric (TE) devices recycle high-temperature waste-heat efficiently, but waste-heat below sub-250 °C remains uncaptured. As promoting full autonomy for the Internet of Things (IoT), we present a TE generator using multilayered pseudo--type GaN/TiN/GaN and -type TiO/TiN/TiO TE one-leg devices, where heterozygous of outer/inner layers demonstrates the functions of a colossal Seebeck coefficient ( = +15,000 μV K) with phonon-assist hopping, controlling by the porosity for reducing thermal conductivity (κ), a high electric conductivity (σ) with reducing κ by outer layers, and σ- coexistence over singular curve by the asymmetric electrode configuration. is elucidated hopping among inner grains and the space charge (SC) grain boundary (GB) of 100 μm regions within Debye length.

The T315I-inclusive compound mutation, the multiple mutations including the T315I mutation on the same BCR::ABL1 gene, confers resistance to diverse tyrosine kinase inhibitors (TKIs). Development of the F311I/T315I compound mutation has been reported in chronic myeloid leukemia patients who sequentially showed clinical resistance to imatinib and dasatinib. The establishment of a human leukemia model with the T315I-inclusive compound mutation remains an experimental challenge.

Capacitance enhancement by ion-laminated borophene-like layered materials.

Nat Commun

January 2025

Laboratory for Chemistry and Life Science, Institute of Integrated Research, Institute of Science Tokyo, Yokohama, 226-8501, Japan.

Atomically flat two-dimensional networks of boron are attracting attention as post-graphene materials. An introduction of cations between the boron atomic layers can exhibit unique electronic functions that are not achieved by neutral graphene or its derivatives. In the present study, we propose a synthesis strategy for ion-laminated boron layered materials in a solution phase, which enables the preparation of analogs by changing the alkali-metal species.

Neurons in the cerebral cortex and hippocampus discharge synchronously in brain state-dependent manner to transfer information. Published studies have highlighted the temporal coordination of neuronal activities between the hippocampus and a neocortical area, however, how the spatial extent of neocortical activity relates to hippocampal activity remains partially unknown. We imaged mesoscopic neocortical activity while recording hippocampal local field potentials in anesthetized and unanesthetized GCaMP-expressing transgenic mice.

The number and variety of identified histone post-translational modifications (PTMs) are continually increasing. However, the specific consequences of each histone PTM remain largely unclear, primarily due to the lack of methods for selectively and rapidly introducing a desired histone PTM in living cells without genetic engineering. Here, we report the development of a cell-permeable histone acetylation catalyst, BAHA-LANA-PEG-CPP44, which selectively enters leukemia cells, binds to chromatin, and acetylates H2BK120 of endogenous histones in a short reaction time.

Department of Dentistry (Oral & Maxillofacial Surgery), Dongsan Medical Center, Keimyung University, School of Medicine, Dalgubeoldaero 1035, Dalseogu, Daegu, 42601, Republic of Korea. Electronic address:

This study aimed to investigate the computed tomography (CT) values and morphology of the temporomandibular joint (TMJ), specifically the condyle and glenoid fossa, in female patients with jaw deformities before and after orthognathic surgery. The maximum CT values were measured on the condylar and glenoid fossa surfaces. In addition, the height, length, and area of the glenoid fossa in the sagittal plane were evaluated for the bilateral TMJs, preoperatively and one year postoperatively.

The latest World Health Organization (WHO) classification of central nervous system tumors (WHO2021/5th) has incorporated molecular information into the diagnosis of each brain tumor type including diffuse glioma. Therefore, an artificial intelligence (AI) framework for learning histological patterns and predicting important genetic events would be useful for future studies and applications. Using the concept of multiple-instance learning, we developed an AI framework named GLioma Image-level and Slide-level gene Predictor (GLISP) to predict nine genetic abnormalities in hematoxylin and eosin sections: , , mutations, promoter mutations, homozygous deletion (CHD), amplification (amp), 7 gain/10 loss (7+/10-), 1p/19q co-deletion, and promoter methylation.

Elevated A2F bisect N-glycans of serum IgA reflect progression of liver fibrosis in patients with MASLD.

J Gastroenterol

January 2025

Department of Gastroenterology and Hepatology, Graduate School of Medicine, Hokkaido University, Hokkaido, Japan.

Background: Advanced liver fibrosis in cases of metabolic dysfunction-associated steatotic liver disease (MASLD) leads to cirrhosis and hepatocellular carcinoma. The current gold standard for liver fibrosis is invasive liver biopsy. Therefore, a less invasive biomarker that accurately reflects the stage of liver fibrosis is highly desirable.

Evaluation of Lower Lip Hypoesthesia Using Trigeminal Somatosensory Evoked Potential After Sagittal Split Ramus Osteotomy: Retrospective Study.

J Craniofac Surg

January 2025

Department of Oral and Maxillofacial Surgery, Division of Medicine, Interdisciplinary Graduate School, University of Yamanashi, Yamanashi, Japan.

Objective: This study evaluated the degree of paresthesia and recovery of the lower lip and chin in patients who underwent sagittal split ramus osteotomy (SSRO) by measuring the preoperative and postoperative trigeminal somatosensory evoked potential (TSEP).

Study Design: Thirty-seven patients with skeletal class II and III malocclusion who underwent SSRO were included. TSEP was measured at 7 points: preoperatively and 1 week, 1, 3, 6, 12, and 18 months postoperatively.

Cancer cells in the tumour microenvironment use various mechanisms to evade the immune system, particularly T cell attack. For example, metabolic reprogramming in the tumour microenvironment and mitochondrial dysfunction in tumour-infiltrating lymphocytes (TILs) impair antitumour immune responses. However, detailed mechanisms of such processes remain unclear.

Live imaging of paracrine signaling: Advances in visualization and tracking techniques.

Cell Struct Funct

January 2025

Department of Pathology and Biology of Diseases, Graduate School of Medicine, Kyoto University.

Live imaging techniques have revolutionized our understanding of paracrine signaling, a crucial form of cell-to-cell communication in biological processes. This review examines recent advances in visualizing and tracking paracrine factors through four key stages: secretion from producing cells, diffusion through extracellular space, binding to target cells, and activation of intracellular signaling within target cells. Paracrine factor secretion can be directly visualized by fluorescent protein tagging to ligand, or indirectly by visualizing the cleavage of the transmembrane pro-ligands or plasma membrane fusion of endosomes comprising the paracrine factors.

Obesity exacerbates susceptibility to infectious diseases. We investigated the effects of a high-fat diet (HFD) on intestinal immunity, particularly immunoglobulin (Ig)A-producing cells, B-cell activating factor (BAFF), and a proliferation-inducing ligand (APRIL) localization. Mice (4- to 20-weeks old) were fed HFD or standard chow diet, and their jejunum and ileum were fixed using the in vivo cryotechnique.

Rationale: Chronic knee pain is a common health issue that requires effective and noninvasive treatment. We devised a novel noninvasive approach using ultrasound-guided electrical nerve reactivation (ENR) in which ultrasound is used to identify the genicular nerve (GN). Then, transcutaneous low-frequency stimulation is applied for 10 seconds.

Amyotrophic lateral sclerosis (ALS) is characterized by the mislocalization and abnormal deposition of TAR DNA-binding protein 43 (TDP-43). This protein plays important roles in RNA metabolism and transport in motor neurons and glial cells. In addition, abnormal iron accumulation and oxidative stress are observed in the brain and spinal cord of patients with ALS exhibiting TDP-43 pathology and in animal models of ALS.

Aims/introduction: Patients with type 2 diabetes are at high risk of developing steatotic liver disease (SLD). Weight loss has proven effective in treating metabolic dysfunction-associated steatotic liver disease (MASLD) in obese patients with type 2 diabetes, with sodium-glucose cotransporter 2 (SGLT2) inhibitors showing promising results. However, lean MASLD is more prevalent in Japan, necessitating alternative approaches to body weight reduction.
