Comparison between two statistical downscaling methods for summer daily rainfall in Chongqing, China
Two circulation index-based methods were applied to downscale summer daily rainfall at four meteorological stations in Chongqing, China. One is a regression method (CIM) and the other a hybrid circulation classification plus regression method (CPM). Both methods used the same three circulation indices and surface specific humidity as predictors. In the first method (CIM), the indices and humidity
Systemic administration of anti-urokinase plasminogen activator receptor monoclonal antibodies induces hepatic fibrin deposition in tissue-type plasminogen activator deficient mice
BACKGROUND: Degradation of extracellular matrix proteins, such as fibrin, is pivotal to tumor invasion. Inhibition of the interaction between urokinase plasminogen activator (u-PA) and its receptor (u-PAR), and hence pro-u-PA activation, is an attractive approach to anti-invasive cancer therapy. A number of inhibitors exist for the human system, but because of species specificity none of these are
Expression analysis of pluripotency-associated genes in human fetal neural stem cells during differentiation.
L1-L2 convergence in clausal packaging in Japanese and English
This study investigates L1-L2 convergence among bilinguals at an intermediate (CEFR-B2) level of L2 proficiency, focusing on the clausal packaging of Manner and Path of motion. Previous research has shown that Japanese speakers use multi-clause and English speakers single-clause constructions (Allen et al., 2003; Kita & Özyürek, 2003). We compared descriptions of motion from monolingual Englis
B-cell precursor t(8;14)(q11;q32)-positive acute lymphoblastic leukemia in children is strongly associated with Down syndrome or with a concomitant Philadelphia chromosome.
We review the clinical and cytogenetic features of 44 acute lymphoblastic leukemias (ALLs) with t(8;14)(q11;q32), including three from our department and 41 ascertained in the literature, focusing on age and gender distribution, peripheral blood values, immunophenotypic data, survival and additional chromosomal changes. Most patients are children or young adults, with a median age of 10 yr for chi
Transthyretin as a potential CSF biomarker for Alzheimer's disease and dementia with Lewy bodies: effects of treatment with cholinesterase inhibitors.
Background: Previous studies have indicated that transthyretin (TTR) levels in cerebrospinal fluid (CSF) are altered in depression and dementia. The present study aimed to investigate whether CSF TTR can be used to discriminate between patients with Alzheimer's disease (AD) and patients with dementia with Lewy bodies (DLB) with or without medication, as well as to reveal whether CSF TTR correlates
Nonfamilial breast cancer subtypes.
Over the last decade, our knowledge in somatic genetic events related to breast cancer has increased -enormously. Through usage of various genome-wide molecular approaches, it has become increasingly clear that breast cancer is a vastly heterogeneous disease. Microarray-based gene expression profiling has divided breast cancer into five distinct intrinsic subtypes termed basal-like, HER2-enriched,
Emerging dipeptidyl peptidase-4 inhibitors for the treatment of diabetes.
Inhibition of dipeptidyl peptidase-4 (DPP-4) prevents the inactivation of glucagon-like peptide-1 (GLP-1). This increases circulating levels of active GLP-1, stimulates insulin secretion and inhibits glucagon secretion, resulting in lowering of glucose levels and improvement of glycemic control in patients with type 2 diabetes. Several DPP-4 inhibitors are emerging for therapeutic use. Most experi
Validation of a modified EuroSCORE risk stratification model for cardiac surgery: the Swedish experience.
Objective: The European System for Cardiac Operative Risk Evaluation (EuroSCORE) is used to identify patients at high risk for aortic valve replacement (AVR) in whom alternative procedures, such as trans-catheter aortic valve implantation (TAVI), may be appropriate. The aim of the present study was to calibrate and validate the EuroSCORE for different cardiac surgery procedures to improve patient
Cerebrospinal fluid biomarker results in relation to neuropathological dementia diagnoses.
BACKGROUND: Clinical dementia diagnoses are not always consistent with neuropathological findings. As correct diagnosis is important for treatment and care, new diagnostic possibilities for dementia are in demand. Cerebrospinal fluid biomarkers should ideally be able to identify ongoing processes in the brain, but need to be further compared with neuropathological findings for evaluation of their
Efficient induction of functional neurons from adult human fibroblasts.
Cellular reprogramming is a rapidly developing technology by which somatic cells are turned into pluripotent stem cells or other somatic cell types through expression of specific combinations of genes. This allows for the generation of patient-specific cell lines that can serve as tools for understanding disease pathogenesis, for drug screens and, potentially, for cell replacement therapies. Sever
Multiple polynomial regression method for determination of biomedical optical properties from integrating sphere measurements
We present a new, to our knowledge, method for extracting optical properties from integrating sphere measurements on thin biological samples. The method is based on multivariate calibration techniques involving Monte Carlo simulations, multiple polynomial regression, and a Newton-Raphson algorithm for solving nonlinear equation systems. Prediction tests with simulated data showed that the mean rel
Suppression of sulfonylurea- and glucose-induced insulin secretion in vitro and in vivo in mice lacking the chloride transport protein ClC-3.
Priming of insulin secretory granules for release requires intragranular acidification and depends on vesicular Cl(-)-fluxes, but the identity of the chloride transporter/ion channel involved is unknown. We tested the hypothesis that the chloride transport protein ClC-3 fulfills these actions in pancreatic beta cells. In ClC-3(-/-) mice, insulin secretion evoked by membrane depolarization (high ex
Expression of a Core 3 Disialyl-Le(x) Hexasaccharide in Human Colorectal Cancers: A Potential Marker of Malignant Transformation in Colon.
Cancer-associated alterations in cell surface and secreted glycoproteins have been catalogued for many years but many of the studies of alterations in mucin carbohydrate have relied on histochemical or immunohistochemical methods, with little direct chemical analysis. In this study, we analyzed the O-glycosylation pattern of MUC2 glycoprotein isolated from colorectal carcinomas, transitional mucos
Fictional Death and Scientific Truth: The Truth-value of Science in Contemporary Forensic Crime Fiction
The author explores the relationship between science and truth in forensic crime fiction by analysis of narrative and media specific constituents of CSI: Crime Scene Investigation and Cornwell’s The Scarpetta Factor. Both are found to convey strong bonds between science and truth, and readers/viewers are likely to assume that this is the case also in the external world.
Sustainable assessment? Critical features of the assessment process in a modularised engineering programme
A New Easy-to-Prepare Homogeneous Continuous Electrochromatographic Bed for Enantiomer Recognition
Completely homogeneous polyacrylamide-based gels were used for capillary electrochromatography (CEC) of drug enantiomers. Like continuous beds (also called continuous polymer rods, silica rods, monoliths) they do not require frits to support the bed, because it is covalently linked to the capillary wall. Along lifetime is an important feature of the beds. The gel matrices can be prepared in any la
Environmental concern, self-concept and defence style. A study of the Agenda 21 process in a Swedish municipality
The experience of working with Agenda 21 was investigated among child care personnel in a small Swedish municipality. The main aim was to study the correlation between environmental concern and personality. It was hypothesised that people caring about the environment would have a positive self-concept and use an adaptive defence style. The result showed that personal concern ( r =0.42, p =0.000),
