Fibrolamellar hepatocellular carcinoma: a case report and gene analysis.

Background: Fibrolamellar hepatocellular carcinoma (HCC) (FL-HCC) is rare in Japan. FL-HCC develops in young patients with no history of cirrhosis and tends to manifest lymphatic metastasis with clinical features similar to those of HCC. We present a case of FL-HCC in a young male patient.

Primary tracheobronchial necrosis after esophagectomy: A nationwide multicenter retrospective study in Japan.

Background: The clinical features of postoperative primary tracheobronchial necrosis (P-TBN; the necrosis without anastomotic leakage or other cervical and mediastinal abscess) remains unclear. This nationwide multicenter retrospective study first investigated the clinical features of P-TBN after esophagectomy for upper aerodigestive tract cancer with a large cohort.

Methods: As a study of the Japan Broncho-Esophagological Society, a nationwide questionnaire survey was conducted in 67 institutions.

Reorganization, specialization, and degradation of oocyte maternal components for early development.

Background: Oocyte components are maternally provided, solely determine oocyte quality, and coordinately determine embryo quality with zygotic gene expression. During oocyte maturation, maternal organelles are drastically reorganized and specialized to support oocyte characteristics. A large number of maternal components are actively degraded after fertilization and gradually replaced by zygotic gene products.

Rationale and Design of Rivaroxaban Estimation With Warfarin in Atrial Fibrillation Patients With Coronary Stent Implantation (REWRAPS).

Recent major randomized trials revealed the superiority of non-vitamin K antagonist oral anticoagulants (NOACs) over vitamin K antagonists (VKAs) from 6 months to 2 years after percutaneous coronary intervention (PCI). However, whether NOAC monotherapy superiority over warfarin continues in real-world patients with a history of atrial fibrillation (AF), coronary stenting, and underlying chronic kidney disease (CKD) >1 year after PCI (e.g.

Case of pneumatosis cystoides intestinalis with intra-abdominal free air developed during treatment with voglibose.

Contrast-enhanced computed tomography (CT) scan (portal phase) at the onset. Emphysema is detected in the ileal wall (b, c: Arrows) and free air is detected in the abdominal cavity (a: Arrowhead). CT scan imaging settings: (a-c) window level (WL) 60 and window width (WW) 300.

Enzalutamide + androgen deprivation therapy (ADT) versus flutamide + ADT in Japanese men with castration-resistant prostate cancer: AFTERCAB study.

Objectives: The objective of the study is to compare the efficacy and safety of alternative androgen therapy (AAT) with enzalutamide + androgen deprivation therapy (ADT) and flutamide + ADT in the treatment of Japanese men with metastatic or nonmetastatic castration-resistant prostate cancer (CRPC) who progressed despite combined androgen blockade (CAB) with bicalutamide + ADT. AAT treatment sequence was also investigated.

Materials And Methods: The open-label, Phase 4 AFTERCAB study (NCT02918968) was conducted from November 2016 to March 2020 in Japanese men aged ≥20 years with asymptomatic or mildly symptomatic CRPC.

Fibroblast-derived prolargin is a tumor suppressor in hepatocellular carcinoma.

Cancer-associated fibroblasts (CAF) are important constituents of the tumor microenvironment (TME) and are major drivers of tumorigenesis. Yet, therapies aiming at eliminating CAF have failed to cure patients. This setback has raised questions regarding whether CAF exclusively favour cancer progression, or if they may also assume tumor-suppressor functions.

Role of surgical resection and its alternative local therapy for pulmonary metastasis of colorectal cancer.

We reviewed surgical and alternative treatments for pulmonary metastasis of colorectal cancer, focusing on recent reports. The standard treatment for pulmonary metastasis of colorectal cancer is pulmonary resection, if resectable, despite the fact that the metastasis is hematogenous to distant organs. Guidelines in several countries, including Japan, have described pulmonary resection as a useful option because of the favorable long-term prognosis reported in various studies pertaining to pulmonary resection.

Ciliary GPCR-based transcriptome as a key regulator of cilia length control.

The primary cilium is a plasma membrane-protruding sensory organelle that efficiently conveys signaling cascades in a highly ordered microenvironment. Its signaling is mediated, in part, by a limited set of GPCRs preferentially enriched in the cilium membrane. This includes melanin-concentrating hormone (MCH) receptor 1 (MCHR1), which plays a role in feeding and mood.

Relationship between upper limb injuries and hip range of motion and strength in high school baseball pitchers.

We aimed to examine the relationship between hip range of motion (ROM) and abduction strength and throwing-related shoulder/elbow injuries in high school baseball pitchers. The study included 135 baseball pitchers. We asked them to fill out a questionnaire at the checkups, that included the dominant arm and the years of baseball experience.

Synaptic Ensemble Underlying the Selection and Consolidation of Neuronal Circuits during Learning.

Memories are crucial to the cognitive essence of who we are as human beings. Accumulating evidence has suggested that memories are stored as a subset of neurons that probably fire together in the same ensemble. Such formation of cell ensembles must meet contradictory requirements of being plastic and responsive during learning, but also stable in order to maintain the memory.

Distinct and Cooperative Functions for the -α, -β and -γ Clusters in Neuronal Survival and Axon Targeting.

The clustered () genes are divided into the αβ, and γ clusters. Gene-disruption analyses in mice have revealed the functions of the α and γ clusters. However, all Pcdh protein isoforms form combinatorial -hetero dimers and enter -homophilic interactions.

Being in a Romantic Relationship Is Associated with Reduced Gray Matter Density in Striatum and Increased Subjective Happiness.

Romantic relationship, a widespread feature of human society, is one of the most influential factors in daily life. Although stimuli related to romantic love or being in a romantic relationship commonly result in enhancement of activation or functional connectivity of the reward system, including the striatum, the structure underlying romantic relationship-related regions remain unclear. Because individual experiences can alter gray matter within the adult human brain, we hypothesized that romantic relationship is associated with structural differences in the striatum related to the positive subjective experience of being in a romantic relationship.

Sweet Taste Receptor Serves to Activate Glucose- and Leptin-Responsive Neurons in the Hypothalamic Arcuate Nucleus and Participates in Glucose Responsiveness.

The hypothalamic feeding center plays an important role in energy homeostasis. In the feeding center, whole-body energy signals including hormones and nutrients are sensed, processed, and integrated. As a result, food intake and energy expenditure are regulated.

Factors influencing trough and 90-minute plasma dabigatran etexilate concentrations among patients with non-valvular atrial fibrillation.

Introduction: Dabigatran etexilate, a direct oral anti-coagulation agent, is used in the prevention of thromboembolism in patients with non-valvular atrial fibrillation (NVAF). However, for reasons that are not fully understood, plasma dabigatran etexilate concentrations (PDC) vary significantly among patients.

Methods: We measured trough and 90min PDC in 98 patients with NVAF.

Prognosis and segment-specific nodal spread of primary lung cancer in the right lower lobe.

Background: Although lobe-specific nodal spread of primary lung cancer has been recently described, segment-specific nodal spread remains unclear. We investigated the frequency of hailer and mediastinal lymph node involvement and survival in patients with tumors located in the superior segment (SS) and basal segment (BS) in the right lower lobe.

Methods: Two hundred and sixty-three patients with primary lung cancer originating in the right lower lobe underwent lobectomy with systematic mediastinal lymph node dissection.

Progression after spontaneous regression in lung large cell neuroendocrine carcinoma: Report of a curative resection.

We present the first reported case of lung large cell neuroendocrine carcinoma (LCNEC) with spontaneous regression followed by progression. An 85-year-old woman presented with a 2.8-cm nodule in the right upper lung lobe on chest computed tomography.

A transient resistance to blood-stage malaria in interferon-γ-deficient mice through impaired production of the host cells preferred by malaria parasites.

IFN-γ plays both pathological and protective roles during blood-stage malaria. One of its pathological roles is its contribution to anemia by suppressing erythropoiesis. Here, to evaluate the effects of IFN-γ-mediated alterations in erythropoiesis on the course of malaria infection, mice deficient in IFN-γ (GKO) were infected with two strains of the rodent malaria parasite Plasmodium yoelii, 17XL (PyL) and 17XNL (PyNL), whose host cell ranges differ.

Return of the glucoreceptor: Glucose activates the glucose-sensing receptor T1R3 and facilitates metabolism in pancreatic β-cells.

Subunits of the sweet taste receptor, namely T1R2 and T1R3, are expressed in mouse pancreatic islets. Quantitatively, the expression of messenger ribonucleic acid for T1R2 is much lower than that of T1R3, and immunoreactive T1R2 is in fact undetectable. Presumably, a homodimer of T1R3 could function as a signaling receptor.

Induction of pluripotency in human somatic cells via a transient state resembling primitive streak-like mesendoderm.

During mammalian embryonic development, the primitive streak initiates the differentiation of pluripotent epiblast cells into germ layers. Pluripotency can be reacquired in committed somatic cells using a combination of a handful of transcription factors, such as OCT3/4, SOX2, KLF4 and c-MYC (hereafter referred to as OSKM), albeit with low efficiency. Here we show that during OSKM-induced reprogramming towards pluripotency in human cells, intermediate cells transiently show gene expression profiles resembling mesendoderm, which is a major component of the primitive streak.

Interference of bacterial cell-to-cell communication: a new concept of antimicrobial chemotherapy breaks antibiotic resistance.

Bacteria use a cell-to-cell communication activity termed "quorum sensing" to coordinate group behaviors in a cell density dependent manner. Quorum sensing influences the expression profile of diverse genes, including antibiotic tolerance and virulence determinants, via specific chemical compounds called "autoinducers". During quorum sensing, Gram-negative bacteria typically use an acylated homoserine lactone (AHL) called autoinducer 1.
