OBJECTIVE: Preston et al. indicated that Protein S (PS) deficiency was associated with stillbirths but not miscarriages. The PS-Tokushima missense variant was reported to serve as a genetic risk factor for deep vein thrombosis in the Japanese population. A previous cross-sectional study showed no increase in the prevalence of PS-Tokushima in patients with recurrent early pregnancy loss or in patients with intra uterine fetal death and/or fetal growth restriction. There has been limited number of prospective studies examining the pregnancy outcome in patients with both a PS deficiency and recurrent pregnancy loss (RPL)...

BACKGROUND: Sleep has been reported to be an important factor in bone metabolism, and sympathetic nervous system activity has been reported to regulate bone metabolism. In this study, we evaluated the association between sleep, sympathetic nervous system activity, and bone mass. METHODS: The study subjects were 221 individuals (108 males; 113 females; mean age: 55.1±7.0years) divided into two groups: those who slept for less than 6h a day (short sleep [SS] group), and those who slept 6h or longer (normal sleep [NS] group)...

The official material used in table tennis balls was changed from celluloid to plastic, a material free of celluloid, in 2014. The purpose of this study was to understand the differences and similarities in the two types of ball materials by comparing their behavior upon collision with a table. The behavior of the balls before and after collision with a table, at various initial speeds ranging from 15 to 115 km/h, was captured using high-speed cameras. Velocities and spin rates before collision and velocities after collision were computed to calculate the coefficients of restitution and friction...

Ingestion of high fructose corn syrup (HFCS) is associated with the risk of both diabetes and obesity. Rare sugar syrup (RSS) has been developed by alkaline isomerization of HFCS and has anti-obesity and anti-diabetic effects. However, the influence of RSS on glucose metabolism has not been explored. We investigated whether long-term administration of RSS maintains glucose tolerance and whether the underlying mechanism involves hepatic glucokinase translocation. Wistar rats were administered water, RSS, or HFCS in drinking water for 10 weeks, and then evaluated for glucose tolerance, insulin tolerance, liver glycogen content, and subcellular distribution of liver glucokinase...

For the treatment of skull defect compensation after neurosurgery, a customized artificial bone is often employed owing to its toughness and the relative ease of producing cosmetically good result. However, implants are vulnerable to infection and removal of implant is sometimes necessary. Several other treatment options such as autologous bone graft or free flap are likely to be considered for the secondary reconstruction to avoid reinfection; however, reimplantation of artificial bone is beneficial for the patients, being not concerned with donor site morbidity...

BACKGROUND: Although the mainstay of treatment for acute decompensated heart failure (ADHF) is decongestion by diuretic therapy, it is often associated with worsening renal function (WRF). The effect of tolvaptan, a selective V2 receptor antagonist, on WRF in ADHF patients with preserved left ventricular ejection fraction (LVEF) is unknown.Methods and Results:We enrolled 50 consecutive ADHF patients whose LVEF on admission was ≥45%. Patients were randomly assigned to either tolvaptan add-on (n=26) or conventional diuretic therapy (n=24)...

BACKGROUND: Although a multidisciplinary approach is often recommended to treat intractable pain, this approach does not completely prevent uncontrolled pain in some patients. The aim of this retrospective study was to investigate the exacerbating factors of prolonged, intractable pain among patients being treated at a pain liaison clinic. METHODS: The participants of this study were 94 outpatients (32 men, 62 women) with chronic intractable pain who visited our hospital between April 2013 and February 2015...

PRG4 is one of the downstream molecules of the myxoid liposarcoma (MLS)-specific fusion oncoproteins TLS-CHOP and EWS-CHOP. Exogenous PRG4 expression increases the tumorigenicity of cells injected in nude mice. The molecular functions of PRG4 in tumorigenesis and/or tumor progression of MLS cells, however, still remain unclear. In this report, we demonstrated that siRNA-mediated knockdown of PRG4 suppressed the growth of the MLS-derived cell lines 1955/91 and 2645/94. In addition, PRG4 knockdown promoted adipocytic differentiation in 1955/91 cells...

A 152-week-old male Royal College of Surgeons (RCS) rat kept as a non-treated animal in a long-term animal study presented with a soft mass in the anterior mediastinum, which adhered to the pleura of the lung. Histopathologically, the mass mainly consisted of round to short spindle-shaped tumor cells that had infiltrated through the hyperplastic thymic tissue. The tumor cells were arranged in loose to dense sheets. Nuclei were moderate in size and round to spindle-shaped, with small nucleoli. Almost all tumor cells exhibited abundant eosinophilic cytoplasm, including eosinophilic granules of a range of sizes...

Diabetes and salivary gland dysfunction are major factors that induce dental caries in experimental animals, but there are no reports analyzing the association of dental caries and salivary glands in an animal model of diabetes mellitus (DM). To clarify the initial development of dental caries and preceding salivary gland disorder, we performed a histopathological analysis on teeth and salivary glands in diabetic Wistar rats 7 weeks after alloxan treatment (DM group) in comparison with nondiabetic rats (Non-DM group) and functional analysis on saliva secretion during the experimental period...

Alloxan (AL) is a material well-known to induce diabetes. Prior to inducing a prolonged diabetic state, AL causes acute tubulointerstitial nephritis. However, the precise primary target site and mechanism of its nephrotoxicity remain unclear. The objective of this study was to evaluate the morphological characteristics relevant to acute renal toxicity following AL administration. Rats were intravenously treated with AL. Eight hours after AL treatment, aquaporin 1-negative and Na/K pump-positive thick ascending limbs of Henle (TAL) were degenerated in the outer medulla...

A 75-year-old man was referred to our hospital for evaluation of persistent anemia. Despite repeated diagnostic tests, including bone marrow aspiration, the cause of his anemia remained unknown. On each occasion, computed tomography had revealed neither swollen lymph nodes nor splenomegaly. After a 10-year follow-up period, he was admitted with general fatigue and had developed splenomegaly as well as the anemia. Bone marrow biopsy revealed increased abnormal lymphocytes with short villi that were positive for CD11c, CD19, CD20, and kappa chain, but not for CD5, CD10, CD23, or cyclin D1, according to flow cytometry...

Goadsporin (GS) is a member of ribosomally synthesized and post-translationally modified peptides (RiPPs), containing an N-terminal acetyl moiety, six azoles and two dehydroalanines in the peptidic main chain. Although the enzymes involved in GS biosynthesis have been defined, the principle of how the respective enzymes control the specific modifications remains elusive. Here we report a one-pot synthesis of GS using the enzymes reconstituted in the 'flexible' in vitro translation system, referred to as the FIT-GS system...

Additional risk stratification may provide more aggressive and focalized preventive treatment to high-risk hypertensive patients according to the Japanese hypertension guidelines. We prospectively investigated the predictive value of high-sensitivity troponin I (hsTnI), both independently and in combination with N-terminal pro-B-type natriuretic peptide (NT-proBNP), for incident heart failure (HF) in high-risk hypertensive patients with preserved left ventricular ejection fraction (LVEF). Baseline hsTnI and NT-proBNP levels and echocardiography data were obtained for 493 Japanese hypertensive outpatients (mean age, 68...
