Early and late mortality after diagnosis of wilms tumor.

PURPOSE To assess rates and causes of mortality in patients with Wilms tumor (WT). METHODS Through 2002, 6,185 patients enrolled onto the National Wilms Tumor Study between 1969 and 1995 were actively observed. Deaths were classified on the basis of medical records as the result of original disease, late effects (including second malignant neoplasms [SMNs], cardiac causes, pulmonary disease, and renal failure), or other causes. Standardized mortality ratios (SMRs) and Cox regression were used to assess the effects of sex, age, and calendar period of diagnosis on mortality. RESULTS Within 5 years of WT diagnosis, 819 deaths occurred, and 159 deaths occurred among 4,972 known 5-year survivors. The SMR was 24.3 (95% CI, 22.6 to 26.0) for the first 5 years, was 12.6 (95% CI, 10.0 to 15.7) for the next 5 years, and remained greater than 3.0 thereafter. For deaths in the first 5 years, the mortality risk decreased by 5-year calendar period of diagnosis (rate ratio [RR] = 0.78 per period). No such trend occurred for later deaths. Among 5-year survivors, 62 deaths were attributed to late effects of treatment or disease, including 27 to SMNs. A trend of decreased risk with calendar period of diagnosis was observed for late-effects mortality (RR = 0.86; 95% CI, 0.67 to 1.10) and for SMN mortality (RR = 0.82; 95% CI, 0.55 to 1.21). CONCLUSION Although the survival outlook for WT patients has improved greatly over time, survivors remain at elevated risk for death many years after their original diagnosis.
A Versatile Monosaccharide Transporter That Operates in the Arbuscular Mycorrhizal Fungus Glomus sp Is Crucial for the Symbiotic Relationship with Plants[C][W]

Carbon allocation to arbuscular mycorrhizal fungi is the reward that plants offer their symbiotic partners in exchange for mineral nutrients. This study identifies a monosaccharide transporter that plays a key role in this process. For more than 400 million years, plants have maintained a mutualistic symbiosis with arbuscular mycorrhizal (AM) fungi. This evolutionary success can be traced to the role of these fungi in providing plants with mineral nutrients, particularly phosphate. In return, photosynthates are given to the fungus, which support its obligate biotrophic lifestyle. Although the mechanisms involved in phosphate transfer have been extensively studied, less is known about the reciprocal transfer of carbon. Here, we present the high-affinity Monosaccharide Transporter2 (MST2) from Glomus sp with a broad substrate spectrum that functions at several symbiotic root locations. Plant cell wall sugars can efficiently outcompete the Glc uptake capacity of MST2, suggesting they can serve as alternative carbon sources. MST2 expression closely correlates with that of the mycorrhiza-specific Phosphate Transporter4 (PT4). Furthermore, reduction of MST2 expression using host-induced gene silencing resulted in impaired mycorrhiza formation, malformed arbuscules, and reduced PT4 expression. These findings highlight the symbiotic role of MST2 and support the hypothesis that the exchange of carbon for phosphate is tightly linked. Unexpectedly, we found that the external mycelium of AM fungi is able to take up sugars in a proton-dependent manner. These results imply that the sugar uptake system operating in this symbiosis is more complex than previously anticipated.
The Theoretical Framework and Application Frontier of Socioemotional Wealth Theory: A Literature Review from the Perspective of Family Firm

For decades, family firms have received high attention from the society, especially from academy community. However, researches on family firms had been relying on other subject’s theories and frameworks in the absence of its own unique theory system. Finally, in 2007, Gomez-Mejia and other scholars put forward a brand new theory-Socioemotional Wealth Theory (SEW). The appearance of the new theory enabled people to set up a framework of interpretation. Nowadays, as the new theory entirely fits in with the features and situations of family firms, it has gradually become a dominant interpretation framework in the field, providing a new perspective for study. We hope that, through analyzing and summarizing the existing researches on Socioemotional Wealth Theory, including its rising up, content and constitutional dimensions, measurement, and factors that influence the decisions and preferences of family firms, this article could provide some references for subsequent discussion and study.
Recovery of Infectious Rabbit Hemorrhagic Disease Virus from Rabbits after Direct Inoculation with In Vitro-Transcribed RNA

ABSTRACT We report the first full-length infectious clone of strain JX/CHA/97 of rabbit hemorrhagic disease virus (RHDV). The transcripts from the full-length cDNA clones were infectious when they were directly injected into rabbits. The sequence of the virus recovered from the rabbits was identical to that of the injected RNA transcripts. The cDNA clone was engineered to contain one silent nucleotide change to create an EcoRV site (A to T at nucleotide 2908). The genetic marker was retained in the recovered progeny virus. The transfection of RNA transcripts into RK-13 cells resulted in the synthesis of viral antigens, indicating that the cDNA clones were replication competent. This stable infectious molecular clone should be an important tool for developing a better understanding of the molecular biology and pathogenesis of RHDV.
Identification of potentially toxic compounds in complex extracts of environmental samples using gas chromatography‐mass spectrometry and multivariate data analysis

—In this study, we examined 31 samples of varying chemical composition, including samples of soils from gasworks, coke production sites, and sites where wood preservatives were heavily used; ash and soot from municipal solid waste incinerators; antiskid sand; and dust from areas with heavy road traffic. The samples were comprehensively chemically characterized, especially their polycyclic aromatic compound contents, using gas chromatography‐time‐of‐flight mass spectrometry, whereas their biological effects were assessed using dehydrogenase activity, root growth (Hordeum vulgare), reproduction of springtails (Folsomia candida), algal growth (Desmodesmus subspicatus), germinability (Sinapis alba), Vibrio fischeri, DR‐CALUX, and Ames Salmonella assays. The number of compounds detected in the samples ranged from 123 to 527. Using the multivariate regression technique of partial‐least‐squares projections to latent structures, it was possible to find individual compounds that exhibited strong correlations with the different biological responses. Some of the results, however, indicate that a broader chemical characterization may be needed to identify all the compounds that may cause the measured biological responses.
Tea and cancer.

Tea is one of the most popular beverages consumed worldwide. The relationship between tea consumption and human cancer incidence is an important concern. This topic has been studied in different populations by many investigators, but no clear-cut conclusion can be drawn. Whereas some studies have shown a protective effect of tea consumption against certain types of cancers, other studies have indicated an opposite effect. Our purpose is to provide a critical review of this topic, covering basic chemistry and biochemical activity of tea, epidemiologic investigations, and laboratory studies, as well as possible directions for future research. Studies have demonstrated either a lack of association between tea consumption and cancer incidence at specific organ sites or inconsistent results. On the other hand, many laboratory studies have demonstrated inhibitory effects of tea preparations and tea polyphenols against tumor formation and growth. This inhibitory activity is believed to be mainly due to the antioxidative and possible antiproliferative effects of polyphenolic compounds in green and black tea. These polyphenolics may also inhibit carcinogenesis by blocking the endogenous formation of N-nitroso compounds, suppressing the activation of carcinogens, and trapping of genotoxic agents. The effect of tea consumption on cancer is likely to depend on the causative factors of the specific cancer. Therefore, a protective effect observed on a certain cancer with a specific population may not be observable with a cancer of a different etiology. On the basis of this concept, we suggest future laboratory and epidemiologic studies to elucidate the relationship between tea consumption and human cancer risk.

Abstract This article describes a method for analyzing conversational difficulties and communication breakdown management in hearing-impaired adults and their communicative partners. The focus of the analysis is placed on the examination of conversational floor control, the proportion of repaired and nonrepaired communication breakdowns, and the strategies used by each member of the dyad to repair breakdowns. A case study illustrating the application of the procedure for aural rehabilitation is presented.
Multihazard Weather Risk Perception and Preparedness in Eight Countries

Weather risk perception research lacks multihazard and transcultural datasets. This hypothesis-generating study used a cognitive behavioral approach and Brunswik’s lens model for subjective risk parameters across eight countries. In Germany, Poland, Israel, the United States, Brazil, India, Malaysia, and Australia, 812 field interviews took place with a uniform set of 37 questions about weather interest, media access, elementary meteorological knowledge, weather fear, preparedness, loss due to weather, and sociodemography. The local randomized quota samples were strictly tested for sample errors; however, they cannot be considered representative for individual countries due to sample size and methodology. Highly rated subjective risks included flood, heat, tornado, and lightning. Weather fear was most prominent in the Malaysian sample and lowest in the German. Subjective elements were further explored with bivariate correlations and a multivariate regression analysis. Sociodemography correlated with psychological variables like knowledge, interest, and fear. Fear was related with subjective risk; less educated and informed people were more fearful. A linear regression analysis identified interest, gender, housing type, education, loss due to weather, and local weather access as the significant predictors for preparedness. The level of preparedness was highest in the United States and Australia and lowest in the Malaysian and Brazilian samples. A lack of meteorological training and infrequent loss experiences make media communication important and emphasize the value of repetition for basic information. Elements of this survey can serve to monitor weather-related psychological orientations of vulnerable population groups. Finally, this survey provides a template with which larger representative transcultural multihazard perception studies can be pursued.

The Mo atoms in the title compounds, i.e. triethyl­ammonium cis-tetra­chloro­bis(4-ethyl­pyridine-N)­molybdate(III), cis-(C6H16N)­[MoCl4(C7H9N)2], and trans-tetra­chloro­bis(4-ethyl­pyridine-N)molybdenum(IV), trans-[MoCl4(C7H9N)2], are six-coordinate with octahedral geometry. The Mo atom in the latter complex lies on a site with crystallographic 2/m symmetry.
Global transcriptome profiling identifies KLF15 and SLC25A10 as modifiers of adipocytes insulin sensitivity in obese women

Although the mechanisms linking obesity to insulin resistance (IR) and type 2 diabetes (T2D) are not entirely understood, it is likely that alterations of adipose tissue function are involved. The aim of this study was to identify new genes controlling insulin sensitivity in adipocytes from obese women with either insulin resistant (OIR) or sensitive (OIS) adipocytes. Insulin sensitivity was first determined by measuring lipogenesis in isolated adipocytes from abdominal subcutaneous white adipose tissue (WAT) in a large observational study. Lipogenesis was measured under conditions where glucose transport was the rate limiting step and reflects in vivo insulin sensitivity. We then performed microarray-based transcriptome profiling on subcutaneous WAT specimen from a subgroup of 9 lean, 21 OIS and 18 obese OIR women. We could identify 432 genes that were differentially expressed between the OIR and OIS group (FDR ≤5%). These genes are enriched in pathways related to glucose and amino acid metabolism, cellular respiration, and insulin signaling, and include genes such as SLC2A4, AKT2, as well as genes coding for enzymes in the mitochondria respiratory chain. Two IR-associated genes, KLF15 encoding a transcription factor and SLC25A10 encoding a dicarboxylate carrier, were selected for functional evaluation in adipocytes differentiated in vitro. Knockdown of KLF15 and SLC25A10 using siRNA inhibited insulin-stimulated lipogenesis in adipocytes. Transcriptome profiling of siRNA-treated cells suggested that KLF15 might control insulin sensitivity by influencing expression of PPARG, PXMP2, AQP7, LPL and genes in the mitochondrial respiratory chain. Knockdown of SLC25A10 had only modest impact on the transcriptome, suggesting that it might directly influence insulin sensitivity in adipocytes independently of transcription due to its important role in fatty acid synthesis. In summary, this study identifies novel genes associated with insulin sensitivity in adipocytes in women independently of obesity. KFL15 and SLC25A10 are inhibitors of insulin-stimulated lipogenesis under conditions when glucose transport is the rate limiting step.
"Something to Just Hold On To": Occasional Teaching and Collaborative Inquiry in Precarious Times

This thesis is the product of a collaborative inquiry involving six occasional teachers, myself included, who came together over five months to share our experiences of navigating a teacher labour market ruled by teacher surplus, job shortages, and increasing employment precarity. Together we took an inquiry stance on occasional teaching (Cochran-Smith & Lytle, 2009) and explored the consequences of precarious teacher employment for teaching, learning, working, and living. Here I document the myriad ways precariousness shapes not only our career trajectories but also our everyday experiences of practice, our professional identities as educators, and our engagement in political action and institutional change efforts. I also offer specific processes and interventions that mitigate the risks of long-term employment precarity for teaching and learning. Throughout, I rely on my participants’ words as well as my own to tell a story about our work, what it means to us, and why it matters.
Anti‐EGFR monoclonal antibodies enhance sensitivity to DNA‐damaging agents in BRCA1‐mutated and PTEN‐wild‐type triple‐negative breast cancer cells

Increased epidermal growth factor receptor (EGFR) expression in triple‐negative breast cancer (TNBC) is recognized as a promising therapeutic target, specifically through the use of selective EGFR inhibitors combined with chemotherapies. TNBC is characterized by genetic instability that leads to increased sensitivity to cytotoxic agents. We analyzed the effect of anti‐EGFR monoclonal antibodies (mAbs; cetuximab and panitumumab) in combination with chemotherapeutic agents (docetaxel, cisplatin, and epirubicin) on EGFR‐expressing TNBC cell lines that have different mutation statuses for one oncogene (KRAS) and two tumor suppressor genes (PTEN and BRCA1). Both mAbs failed to improve the cytotoxic effect of chemotherapies in the KRAS mutant cell line (MDA‐MB‐231) and PTEN‐null cell lines (HCC‐1937 and MDA‐MB‐468). In contrast, mAbs combined with DNA‐damaging agents (cisplatin or epirubicin) had a synergistic effect in the BRCA1‐mutant cell line SUM‐1315 (wild‐type KRAS and PTEN). The reintroduction of wild‐type BRCA1 into SUM‐1315 cells abolished this synergism. The improved effect of combination therapy was associated with cell cycle arrest at G1 phase and inhibition of the phosphorylation of EGFR and ERK1/2 proteins. These results suggest that patients with BRCA1‐associated TNBC without genetic alterations in the PTEN and KRAS genes may have improved therapeutic responses to anti‐EGFR mAbs combined with DNA‐damaging agents. © 2017 Wiley Periodicals, Inc.
Is volume transfer coefficient (K(trans)) related to histologic grade in human gliomas?

PURPOSE The purpose of this study was to examine the relationship between contrast transfer coefficient [K(trans)] and grade in gliomas. MATERIAL AND METHODS Median values of K(trans), CBV(T1), and of the 95th percentile (95%) of the distribution (K(trans) [95%] and CBV(T1) [95%]) were calculated in 39 patients with glioma. Group comparisons and post hoc pairwise comparisons were performed. The relationship between variables and grade used Spearman rho and canonical discriminant analysis. The separation of high- from low-grade tumors was separately assessed by using Mann-Whitney U tests and logistic regression. Receiver operator curve analysis was performed for high- and low-grade tumors and grade III and grade IV tumors. RESULTS There were significant differences between grades for all variables (P < .001). Pairwise comparisons demonstrated significant differences between grades II and III and II and IV for all variables except K(trans), which did not show significance in the grade II and III comparison, and between III and IV for CBV(T1) and CBV(T1) (95%; P < .01). All variables correlated with grade (P < .01). Discriminant analysis showed independent relation between both CBV(T1) and K(trans) (95%) and grade, and the canonical function produced a total correct classification of 74.4% of cases. Logistic regression analysis for low- versus high-grade tumors showed K(trans) (95%) and CBV(T1) to be independent factors (P < .01 and P < .05). CONCLUSION There are strong independent relationships between both CBV and K(trans) and histologic grade in gliomas. Both measurements show good discriminative power in distinguishing between low- and high-grade tumors with diagnostic sensitivity and specificity >90%.
The cost of a food-borne outbreak of hepatitis A in Denver, Colo.

BACKGROUND In 1992, a food-borne outbreak of hepatitis A associated with a catering facility in Denver, Colo, resulted in 43 secondary cases of hepatitis A and the potential exposure of approximately 5000 patrons. OBJECTIVES To assess (1) disease control costs, including state and local health department personnel costs, provision and administration of immune globulin, and cost of extra hepatitis A serologic tests performed; (2) business losses; and (3) cost of the cases' illnesses. METHODS Cost data were collected from hospitals, health maintenance organizations, health departments, laboratories, the caterer's insurance company, and the catering facility involved in the outbreak. RESULTS The total costs assessed in the outbreak from a societal perspective were $809,706. Disease control costs were $689,314, which included $450,397 for 16,293 immune globulin injections and $105,699 for 2777 hours of health department personnel time. The cases' medical costs were $46,064, or 7% of the disease control costs. CONCLUSIONS The cases' medical costs and productivity losses were only a minor component of the total cost of this outbreak. The high cost of food-borne outbreaks should be taken into account in economic analyses of the vaccination of food handlers with inactivated hepatitis A vaccine.
Common gene expression signatures in t(8;21)‐ and inv(16)‐acute myeloid leukaemia

Human acute myeloid leukaemia (AML) involving a core‐binding factor (CBF) transcription factor is called CBF leukaemia. In these leukaemias, AML1 (RUNX1, PEBP2αB, CBFα2)‐MTG8 (ETO) and CBFβ (PEBP2β)‐MYH11 chimaeric proteins are generated by t(8;21) and inv(16) respectively. We analysed gene expression profiles of leukaemic cells by microarray, and selected genes whose expression appeared to be modulated in association with t(8;21) and inv(16). In a pair‐wise comparison, 15% of t(8;21)‐associated transcripts exhibited high or low expression in inv(16)‐AML, and 26% of inv(16)‐associated transcripts did so equivalently in t(8;21)‐AML. These common elements in gene expression profiles between t(8;21)‐ and inv(16)‐AML probably reflect the situation that AML1‐MTG8 and CBFβ‐MYH11 chimaeric proteins affect a common set of target genes in CBF leukaemic cells. On the other hand, 38% of t(8;21)‐associated and 24% of inv(16)‐associated transcripts were regulated in t(8;21)‐ and inv(16)‐specific manners. These distinct features of t(8;21)‐ and inv(16)‐associated genes correlate with the bimodular structures of the chimaeric proteins (CBF‐related AML1 and CBFβ portions, and CBF‐unrelated MTG8 and MYH11 portions).
Predominant role of endothelial nitric oxide synthase in vascular endothelial growth factor-induced angiogenesis and vascular permeability

Nitric oxide (NO) plays a critical role in vascular endothelial growth factor (VEGF)-induced angiogenesis and vascular hyperpermeability. However, the relative contribution of different NO synthase (NOS) isoforms to these processes is not known. Here, we evaluated the relative contributions of endothelial and inducible NOS (eNOS and iNOS, respectively) to angiogenesis and permeability of VEGF-induced angiogenic vessels. The contribution of eNOS was assessed by using an eNOS-deficient mouse, and iNOS contribution was assessed by using a selective inhibitor [l-N6-(1-iminoethyl) lysine, l-NIL] and an iNOS-deficient mouse. Angiogenesis was induced by VEGF in type I collagen gels placed in the mouse cranial window. Angiogenesis, vessel diameter, blood flow rate, and vascular permeability were proportional to NO levels measured with microelectrodes: Wild-type (WT) ≥ WT with l-NIL or iNOS−/− > eNOS−/− ≥ eNOS−/− with l-NIL. The role of NOS in VEGF-induced acute vascular permeability increase in quiescent vessels also was determined by using eNOS- and iNOS-deficient mice. VEGF superfusion significantly increased permeability in both WT and iNOS−/− mice but not in eNOS−/− mice. These findings suggest that eNOS plays a predominant role in VEGF-induced angiogenesis and vascular permeability. Thus, selective modulation of eNOS activity is a promising strategy for altering angiogenesis and vascular permeability in vivo.
