Mortality salience (MS) has been shown to lead to derogation of others with dissimilar worldviews, yet recent research has shown that Asian-Americans who presumably adopt an interdependent self-construal (SC) tend to reveal greater tolerance after MS induction. In the present study, we demonstrated that Japanese individuals who are high on interdependent SC indeed show greater tolerance toward worldview-threatening other in the MS (vs control) condition, thus replicating the prior research. Extending this research, we also found that interdependent people's tolerance toward worldview-threatening other was mediated by increased activity in the right ventrolateral prefrontal cortex in the MS condition...

OBJECTIVE: Growth Arrest-Specific 6 (GAS6) is a vitamin K-dependent protein. Despite a similar structure to Protein S, it has no anticoagulant activity. An association between GAS6 and some diseases for adults has been reported. In the absence of prospective clinical studies of GAS6 in neonates, so far, the objective of this study is to obtain, for the first time, plasma GAS6 levels before and after vitamin K1 prophylaxis in full-term and pre-term newborns. METHODS: 80 newborn (40 term and 40 preterm) were recruited for this study...

OBJECTIVE: Breast cancer is the most common malignancy among Turkish women and the rate of early stage disease is increasing. The Oncotype DX 21-gene assay is predictive of distant recurrence in ER-positive, HER2-negative early breast cancer. We aimed to evaluate the correlations between Recurrence Score (RS) and routine risk factors. MATERIALS AND METHODS: Ten academic centers across Turkey participated in this prospective trial. Consecutive patients with breast cancer who had pT1-3, pN0-N1mic, ER-positive, and HER2-negative tumors were identified at tumor conferences...

The Xenopus oocyte is known to accumulate filamentous or F-actin in the nucleus, but it is currently unknown whether F-actin also accumulates in embryo nuclei. Using fluorescence-labeled actin reporters, we examined the actin distribution in Xenopus embryonic cells and found that F-actin accumulates in nuclei during the blastula stage but not during the gastrula stage. To further investigate nuclear F-actin, we devised a Xenopus egg extract that reproduces the formation of nuclei in which F-actin accumulates...

OBJECTIVES: There have been no nationwide epidemiological studies of idiopathic normal pressure hydrocephalus (iNPH) in Japan. Therefore, a nationwide epidemiologic survey of iNPH was performed to determine the number of cases and clinical characteristics by sex and diagnostic level. METHODS: The first survey examined the numbers of cases that met the diagnostic criteria of iNPH and those who underwent shunt operations in 2012. The second survey gathered patients' details to clarify their clinical background characteristics...

Mice lacking Cdk6 kinase activity suffer from mild anemia accompanied by elevated numbers of Ter119+ cells in the bone marrow. The animals show hardly any alterations in erythroid development, indicating that Cdk6 is not required for proliferation and maturation of erythroid cells. There is also no difference in stress erythropoiesis following hemolysis in vivo. However, Cdk6-/- erythrocytes have a shortened lifespan and are more sensitive to mechanical stress in vitro, suggesting differences in the cytoskeletal architecture...

ADP-ribosyltransferases (ARTs) modify proteins with single units or polymers of ADP-ribose to regulate DNA repair. However, the substrates for these enzymes are ill-defined. For example, although histones are modified by ARTs, the sites on these proteins ADP-ribosylated following DNA damage and the ARTs that catalyse these events are unknown. This, in part, is due to the lack of a eukaryotic model that contains ARTs, in addition to histone genes that can be manipulated to assess ADP-ribosylation events in vivo...

In this paper, we propose a computationally efficient spatial differencing matrix set (SDMS) method for two-dimensional direction of arrival (2D DOA) estimation with uniform rectangular arrays (URAs) in a low-grazing angle (LGA) condition. By rearranging the auto-correlation and cross-correlation matrices in turn among different subarrays, the SDMS method can estimate the two parameters independently with one-dimensional (1D) subspace-based estimation techniques, where we only perform difference for auto-correlation matrices and the cross-correlation matrices are kept completely...

OBJECTIVE: Due to the occurrence of severe adverse drug reactions to regorafenib, a drug used in cancer therapy, the identification of a predictive marker(s) is needed to increase the therapeutic applicability of this compound. We therefore investigated whether polymorphisms in the ABCG2 and SLCO1B genes are associated with adverse drug reactions to regorafenib. METHODS: For these analyses, 37 Japanese cancer patients were treated with regorafenib, genotyped for polymorphisms in ABCG2 and SLCO1B, and evaluated for drug-related adverse drug reactions...

The objective of this study was to establish reference intervals for growth arrest-specific 6 (GAS6), a vitamin K-dependent protein, in human adult plasma according to the Guideline of Clinical and Laboratory Standards Institute (CLSI) C28-A3. Blood samples were collected from 308 healthy volunteers aged 18-72 (157 female, 151 male). A non-parametric approach was used to calculate the reference interval. The plasma GAS6 reference interval was determined, with 90% confidence interval: the lower limit (2.5 percentile) was 2...

OBJECTIVE: Anti-epidermal growth factor receptor (EGFR) antibodies and bevacizumab are commonly used, sequentially, as palliative chemotherapies for patients with metastatic colorectal cancer. However, little is known about the efficacy of second-line treatments containing bevacizumab after first-line treatment with an anti-EGFR antibody. METHODS: We retrospectively reviewed 128 patients who received second-line bevacizumab-containing chemotherapy and evaluated the effect of prior use of anti-EGFR antibody on the efficacy of the second-line treatment...

A chemically-activatable alkynyl steroid analogue probe has been synthesized for visualizing the lipid raft membrane domains by Raman microscopy. The Raman probe, in which ring A of its steroid backbone is replaced with an alkynyl group, was designed to enable activation of the alkyne signal through the Eschenmoser-Tanabe fragmentation reaction of the oxidized cholesterol precursor in lipid bilayer membranes. The alkynyl steroid analogue was observed to form liquid-ordered raft-like domains on a model giant-liposome system in a similar manner as cholesterol, and the large alkyne signal of the accumulated probe at 2120 cm(-1) was mapped on the microdomains with a Raman microscope...

We present the case of a 70-year-old man diagnosed with multiple myeloma in 2008, who after four therapy lines initiated a fifth-line treatment with pomalidomide (4 mg orally, days 1-21 of a 28-day cycle) and low-dose dexamethasone (40 mg weekly orally). The patient was treated with pomalidomide for almost 2 years achieving a complete remission after 12 cycles. Complete remission was maintained for 9 months. This case illustrates the potential of pomalidomide plus low-dose dexamethasone to overcome multiple myeloma refractoriness inducing a quick and very prolonged remission...

Selenium is present in proteins in the form of selenocysteine, where this amino acid serves catalytic oxidoreductase functions. The use of selenocysteine in nature is strongly associated with redox catalysis. However, selenium is also found in a 2-selenouridine moiety at the wobble position of tRNA(Glu), tRNA(Gln) and tRNA(Lys). It is thought that the modifications of the wobble position of the tRNA improves the selectivity of the codon-anticodon pair as a result of the physico-chemical changes that result from substitution of sulfur and selenium for oxygen...

Prion diseases are progressive fatal neurodegenerative illnesses caused by the accumulation of transmissible abnormal prion protein (PrP). To find treatments for prion diseases, we searched for substances from natural resources that inhibit abnormal PrP formation in prion-infected cells. We found that high-molecular-weight components from insect cuticle extracts reduced abnormal PrP levels. The chemical nature of these components was consistent with that of melanin. In fact, synthetic melanin produced from tyrosine or 3-hydroxy-l-tyrosine inhibited abnormal PrP formation...

PURPOSE: The purpose of this study was to assess hepatic arterial infusion (HAI) of oxaliplatin combined with intravenous 5-fluorouracil (5-FU) and l-leucovorin (l-LV) in colorectal cancer (CRC) patients with systemic chemotherapy failure in a phase I/II trial. METHODS: CRC patients with unresectable liver metastases following standard systemic chemotherapy failure were eligible. A catheter-port system for HAI was placed using interventional radiology. In phase I, escalating doses of oxaliplatin for levels 1 and 2 were set at 50 and 100 mg/m(2), respectively, and were combined with fixed doses of intravenous 5-FU (200 mg/m(2) bolus and 2400 mg/m(2)/46-h continuous infusion) and l-LV (200 mg/m(2))...

It is well known that 5-fluoroorotic acid (5-FOA)-resistant mutants isolated from wild-type Cryptococcus neoformans are exclusively either ura3 or ura5 mutants. Unexpectedly, many of the 5-FOA-resistant mutants isolated in our selective regime were Ura(+). We identified CNM00460 as the gene responsible for these mutations. Cnm00460 belongs to the nucleobase cation symporter 1/purine-related transporter (NCS1/PRT) super family of fungal transporters, representative members of which are uracil transporter, uridine transporter and allantoin transporter of Saccharomyces cerevisiae...

BACKGROUND: Disseminated intravascular coagulation (DIC) is a rare complication of advanced gastric cancer (AGC). Despite reports of the efficacy of chemotherapy for AGC with DIC, little is known of platinum-based doublet therapy. PATIENTS AND METHODS: We conducted a single-institute, retrospective chart review of 500 consecutive chemotherapy-naïve patients with advanced gastric adenocarcinoma (recurrent or metastatic) from November 2010 to November 2015. RESULTS: Six patients were diagnosed with AGC with DIC (1...

BACKGROUND: Behavioural resilience in mosquitoes poses a significant challenge to mosquito control. Although behaviour changes in anopheline vectors have been reported over the last decade, there are no empirical data to suggest they compromise the efficacy of vector control in reducing malaria transmission. METHODS: In this study, we quantified human exposure to both bites and infective bites of a major malaria vector in Papua New Guinea over the course of four years surrounding a nationwide bednet distribution...
