Controlling the initiation of cell migration plays a fundamental role in shaping the tissue during embryonic development. During gastrulation in zebrafish, some mesendoderm cells migrate inward to form the endoderm as the innermost germ layer along the yolk syncytial layer. However, how the initiation of inward migration is regulated is poorly understood. In this study, we performed light-sheet microscopy-based 3D single-cell tracking consisting of (a) whole-embryo time-lapse imaging with light-sheet microscopy and (b) three-dimensional single cell tracking in the zebrafish gastrula in which cells are marked with histone H2A-mCherry (nuclei) and the sox17:EGFP transgene (expressed in endoderm cells)...

Open reconstruction of superior mesenteric artery aneurysms is very difficult, especially if the lesion is extensive. Aneurysmal lesions were found in a 74-year-old woman during a medical checkup. Computed tomography scan showed a 6.8-cm aneurysm arising 4 cm distal to the superior mesenteric artery origin, in succession to a 2.7-cm aneurysm, and further distal small aneurysms with string-of-beads appearance. The first, second, and third jejunoileal arteries, the middle colic artery, and the ileocolic artery were originated from the aneurysms...

We examined the expansion of target food products for the analysis of polychlorinated biphenyls (PCBs). From our studies in fish using an accelerated solvent extractor (ASE) and GC-MS/MS, we found that recovery of low-chlorinated PCBs (some isomer of 3 or 4 chlorinated PCBs) in specific food products was low. Therefore, we attempted to improve the analytical method. In Japanese sea perch (Suzuki) and milk, freeze drying before extracting with ASE did not sufficiently improve the recovery of low-chlorinated PCBs; however, it was significantly improved by changing the column to a silica gel/H2 SO4 silica gel multilayer column...

Prostaglandin (PG) D2 is a lipid mediator, and in the brain, overproduction of PGD2 is reportedly involved in the progression and exacerbation of neuroinflammation. The objective of this study was to elucidate PGD2 efflux transport, under normal and inflammatory conditions, across the blood-brain barrier (BBB), which is formed by brain capillaries. Elimination of [3 H]PGD2 across the BBB of normal and lipopolysaccharide (LPS)-induced inflammatory rats was examined by the intracerebral microinjection technique...

We treated the case of a 22-year-old male patient with liver dysfunction. At 1 year of age, hepatic fibrosis was suspected. In addition, due to the presence of retinitis pigmentosa, renal failure, obesity, mental retardation, and hypogonadism, he was diagnosed with Bardet-Biedl syndrome (BBS). Skipping of exons 14 and 17 in the sodium channel and clathrin linker 1 (SCLT1) gene was observed. At 22 years of age, the liver enzyme levels were further elevated and a diagnosis of microvesicular steatohepatitis was made...

The c-Kit receptor tyrosine kinase regulates the development and differentiation of several progenitor cells. In the gastrointestinal (GI) tract, the c-Kit regulates the development of the interstitial cells of Cajal (ICC) that are responsible for motility regulation of the GI musculature. W-sash (Wsh ) is an inversion mutation upstream of the c-kit promoter region that affects a key regulatory element, resulting in cell-type-specific altered gene expression, leading to a decrease in the number of mast cells, melanocytes, and ICC...

The filter extraction method is a new, simple method for evaluating anticancer drug contamination in air. The method involves installing a filter in the exhaust port of an exhaust duct on a facility's air conditioner, then collecting and measuring fine particles of the antineoplastic agents adsorbed onto the filter. In this study, we analyzed the utility of maintaining continuous filter extraction for measuring cyclophosphamide and 5-fluorouracil contamination. The filters were installed in 3 areas of an outpatient chemotherapy room and then left in place for approximately 5 months...

This study investigated the role of the PI3K/Akt pathway in cadmium (Cd) induced malignant transformation of normal prostate epithelial (PWR1E and RWPE1) cells. Both PWR1E and RWPE1 cells were exposed to 10 μM Cd for one year and designated as Cd-PWR1E and Cd-RWPE1. Cd-RWPE1 cells robustly formed tumors in athymic nude mice. Functionally, Cd-exposure induced tumorigenic attributes indicated by increased wound healing, migration and invasion capabilities in both cell lines. RT2 -array analysis revealed many oncogenes including P110α, Akt, mTOR, NFKB1 and RAF were induced whereas tumor suppressor (TS) genes were attenuated in Cd-RWPE1...

Extracellular vesicles (EVs), such as exosomes, have garnered increasing interest because of their potential clinical applications that range from diagnostics to therapeutics. The development of an automated and reproducible EV purification platform would therefore aid the introduction of EV biomarkers and therapies into the clinic. Here, we demonstrate that K8- as well as K-16 peptides (containing 8 and 16 lysine residues with dissociation constants of 102 nM and 11.6 nM for phosphatidylserine, respectively) immobilized on magnetic beads can capture small EVs (< 0...

BACKGROUND: Protein arginine methyltransferase 1 (PRMT1), a major type I arginine methyltransferase in mammals, methylates histone and non-histone proteins to regulate various cellular functions such as transcription, DNA damage response, and signal transduction. SCOPE OF REVIEW: This review summarizes previous and recent studies on PRMT1 functions in major cell types of the central nervous system. We also discuss the potential involvement of PRMT1 in neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal dementia...

Papillary thyroid microcarcinoma (PTMC) has the highest incidence among all thyroid carcinomas. Although surgery is the primary treatment for PTMC, it inevitably leads to trauma and some complications. To formulate an optimal treatment strategy, we aim to clarify the risk factors for lymph node metastasis (LNM) in PTMC patients. This study retrospectively analyzed patients who underwent thyroidectomy during 1995-2015, and grouped them according to lymph node metastasis. Age, gender, tumor size, thyroid functions, Hashimoto's thyroiditis, multifocal tumor, extrathyroidal extensions, capsular invasion were analyzed...

Chronic lymphocytic thyroiditis (CLT), also known as Hashimoto's thyroiditis (HT) or autoimmune thyroiditis (AIT), is a T cell-mediated organ-specific autoimmune thyroid disease. It is a common etiology of acquired thyroid dysfunction in pediatrics. In HT, early adolescence is a period of high risk of diagnosis. Henoch-Schönlein purpura (HSP) is the most common primary systemic vasculitis in pediatrics, with small vasculitis as the main lesion. We described a rare case in which a pair of twin sisters were diagnosed with Hashimoto's thyroiditis and allergic purpura...

The efficacy of antipyretics for preventing febrile seizure recurrence has been reported by a recent study, and the results might overturn previous evidence. We systematically reviewed the efficacy of antipyretics in the prevention of febrile seizure recurrence in children focused on the timing of its administration. We searched the Medline, Embase, and Cochrane Central Register of Controlled Trials databases for randomized and quasi-randomized trials and prospective non-randomized studies of aged up to 60 months, diagnosed with febrile seizure, who were treated with antipyretics...

Long non‑coding RNAs (lncRNAs) have been increasingly recognized as important immune checkpoints involved in the pathogenesis of autoimmune diseases. However, the exact role of lncRNAs in Hashimoto's thyroiditis (HT) has been rarely studied. The aim of the present study was to investigate the role of lncRNAs and the potential biomarkers in HT, a total of 33 patients with HT and 32 healthy volunteers were enrolled in the present study, and five patients and five healthy controls were investigated using next generation sequencing...

OBJECTIVES: The myositis-specific autoantibodies that characterise certain forms of idiopathic inflammatory myopathy (IIM) are useful for diagnosing dermatomyositis (DM) / polymyositis (PM) and predicting its prognosis. The autoantibody to phenylalanyl-tRNA synthetase (anti-Zo) has been identified as a disease marker antibody for anti-synthetase syndrome only in a UK cohort. Here we aim to establish an ELISA for the measurement of anti-Zo and to characterise the clinical features of Japanese patients who have this autoantibody...

BACKGROUND:  Hashimoto's thyroiditis (HT) may cause salivary dysfunction in patients resulting in xerostomia, but little is known about changes in salivary function in patients with no obvious dry mouth symptoms. In this study we assessed salivary function in women with HT, who had not experienced xerostomia and, for the first time, evaluated the effects of thyroid auto-antibodies on this function.: METHODS:  Sixty consecutive subjects were included, comprising 32 women (mean age, 36 ± 12 years) diagnosed with HT accompanied by differentiated thyroid cancer (DTC) in the study group (HT group), along with a control group (DTC group) of 28 women (mean age, 40 ± 12 years) diagnosed with DTC only...

BACKGROUND: A few studies have reported the incidence and clinical implications of complications after pleurectomy/decortication (P/D). OBJECTIVE: The aim of this study was to assess the details of complications and predictive factors of particularly durable air leak with P/D. METHODS: Data on 163 consecutive patients who underwent neoadjuvant chemotherapy (NAC) followed by P/D for malignant pleural mesothelioma between September 2012 and May 2020 at our institution were retrospectively analyzed...

Saprophytic bacteria and plants compete for limited nutrient sources. Bacillus subtilis grows well on steamed soybeans Glycine max to produce the fermented food, natto. Here we focus on bacterial responses in conflict between B. subtilis and G. max. B. subtilis cells maintained high growth rates specifically on non-germinating, dead soybean seeds. On the other hand, viable soybean seeds with germinating capability attenuated the initial growth of B. subtilis. Thus, B. subtilis cells may trigger saprophytic growth in response to the physiological status of G...

BACKGROUND: There has been no solid evidence regarding the actual efficacy of adhesion barriers in liver surgery. METHODS: Difficulty grade of lysis of adhesion was evaluated in 122 patients who underwent repeat hepatectomy (ReHx) using the TORAD score. Technical difficulty of lysis of adhesion and incidence of complication were then compared between the group of patients who received a sheet-type adhesion barrier (Seprafilm®) in the previous hepatectomy (n = 70) and those who did not (n = 52) using the inverse probability weighting method...
