Abstract
BACKGROUND Neuroblastoma (NB) is a heterogeneous tumor with extremely diverse prognosis according to clinical and genetic factors such as specific combinations of chromosomal imbalances. METHODS Molecular karyotyping data from a national neuroblastic tumor database of 155 NB samples were analyzed and related to clinical data. RESULTS Segmental chromosomal alterations (SCA) were detected in 102 NB, whereas 45 only displayed numerical alterations. Incidence of SCA was higher in stage M (92%) and MYCN amplified (MNA) NB (96%). Presence of SCA was associated with older age, especially 1q gain and 3p deletion. 96% of the deaths were observed in the SCA group and 85% of the relapsed NB contained SCA. The alteration most commonly associated with a higher number of other segmental rearrangements was 11q deletion, followed by 4p deletion. Whole-chromosome 19 gain was associated with lower stages, absence of SCA and better outcome. CONCLUSIONS SCA are not randomly distributed and are concentrated on recurrent chromosomes. The most frequently affected chromosomes identify prognostic factors in specific risk groups. SCA are associated with older age and MNA. We have identified a small subset of patients with better outcome that share whole-chromosome 19 numeric gain, suggesting its use as a prognostic biomarker in NB.

Abstract
Abstract
Objectives
Lipolysis is the catabolic process that hydrolyzes triglyceride (TG) to free fatty acids (FFAs) and glycerol under negative energy balance such as fasting. In adipocytes, adipose TG lipase (ATGL), hormone-sensitive lipase (HSL), and monoglyceride lipase play key roles in a series of TG hydrolysis reactions in mammals. However, overly activated adipose lipolysis is believed to contribute to link between obesity and systemic inflammation and oxidative stress. We previously demonstrated that piceatannol (PIC), a natural resveratrol analogue, inhibits adipogenesis in cultured adipocytes and lipogenesis in Caenorhabditis elegans. Furthermore, we showed that PIC extends the lifespan of C. elegans via the insulin/IGF-1 signaling. However, the effects of PIC on lipid metabolism during fasting state is unknown.
Methods
We conducted Oil-Red-O assay, Enzyme assay (TG and Free glycerol contents), PCR analysis and lifespan assay.
Results
In this study, we demonstrated that PIC-treated C. elegans exhibited suppressed lipolysis under fasting as judged by increased lipid accumulation and TG levels with decreased free glycerol level. Consistent with these findings, PIC treatment resulted in decreased mRNA levels of genes involved lipolysis such as atgl-1, hosl-1 and aak-2 in fasted C. elegans. Also, PIC treatment augmented fasting-induced lifespan of C. elegans by an increased daf-16 gene expression. However, such effect was abolished when atgl-1, aak-2, and daf-16 mutants were treated with PIC. In addition, we also found that autophagy is required for PIC-induced lifespan in C. elegans during fasting since autophagy inhibitor treatments and autophagy gene deficient worms resulted in blunting the lifespan extension effect of PIC.
Conclusions
Collectively, our results indicate that PIC contributes to lifespan extension in C. elegans during fasting possibly through regulating lipolysis- and/or autophagy-dependent lipid metabolism.

Abstract
The aim of the present study was to evaluate the effects of using ultra-high pressure homogenisation (UHPH) on the composition and biochemistry of starter-free fresh cheeses and to monitor their evolution during cold storage as an alternative to conventional treatments applied in the production of fresh cheese such as conventional pasteurisation and homogenisation-pasteurisation. Although both homogenisation treatments increased cheese moisture content, cheeses from UHPH-treated milk showed lower moisture loss during storage than those from conventionally homogenised-pasteurised milk. Lipolysis and proteolysis levels in cheeses from UHPH-treated milk were lower than those from conventionally treated milk samples. Although, oxidation was found to be the major drawback, in general terms, high quality starter-free fresh cheeses were obtained from UHPH-treated milk.

Abstract
Ewe milk cheeses were submitted to 200, 300, 400, and 500 MPa (2P to 5P) at 2 stages of ripening (after 1 and 15 d of manufacturing; P1 and P15). The high-pressure-treated cheeses showed a more important hydrolysis of beta-casein than control and 2P1 cheeses. Degradation of alpha(s1)-casein was more important in 3P1, 4P1, and P15 cheeses than control and 2P1 cheeses. The 5P1 cheeses exhibited the lowest degradation of alpha(s)-caseins, probably as a consequence of the inactivation of residual chymosin. Treatment at 300 MPa applied on the first day of ripening increased the peptidolytic activity, accelerating the secondary proteolysis of cheeses. The 3P1 cheeses had extensive peptide degradation and the highest content of free amino acids. Treatments at 500 MPa, however, decelerated the proteolysis of cheeses due to a reduction of microbial population and inactivation of enzymes.

Abstract
The effect of high-pressure treatment on the volatile profile of ewe milk cheeses was investigated. Cheeses were submitted to 200, 300, 400 and 500 MPa at 2 stages of ripening (after 1 and 15 d of manufacturing) and volatile compounds were assayed at 15 and 60 d of ripening. High-pressure treatment altered the balance of volatile profile of cheeses, limiting the formation of acids, alcohols, ketones, aldehydes, and sulfur compounds and enhancing the formation of 2,3-butanedione. In general, cheeses pressurized at 15 d of ripening were more similar to untreated cheeses than those treated at 1 d. Cheeses treated at 300 MPa after 1 d of manufacturing were characterized by higher levels of free amino acids, ethanol, ethyl esters, and branched-chain aldehydes, whereas cheeses treated at 500 MPa after 1 d of manufacturing had lower microbial populations, showed the highest abundance of 2,3-butanedione, pyruvaldehyde, and methyl ketones, and the lowest abundance of alcohols.

Abstract
A 21-kDa calmodulin (CaM)-binding protein and a 19-kDa calmodulin-binding protein were detected in 0.1 M CaCl2 extracts of Angelica dahurica L. suspension-cultured cells and carrot (Daucus carota L.) suspension-cultured cells, respectively, using a biotinylated cauliflower CaM gel-overlay technique in the presence of 1 mM Ca2+. No bands, or very weak bands, were shown on sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels overlayed with biotinylated cauliflower CaM when 1 mM Ca2+ was replaced by 5 mM EGTA, indicating that the binding of these two CaM-binding proteins to CaM was dependent on Ca2+. Less 21-kDa CaM-binding protein was found in culture medium of Angelica dahurica suspension cells; however, a 21-kDa protein was abundant in the cell wall. We believe that the 21-kDa CaM-binding protein is mainly in the cell wall of Angelica dahurica. Based on its reaction with periodic acid-Schiff (PAS) reagent, this 21-kDa protein would appear to be a glycoprotein. The 21-kDa CaM-binding protein was purified by a procedure including Sephadex G-100 gel filtration and CM-Sepharose cation-exchange column chromatography. The purity reached 91% according to gel scanning. The purified 21-kDa CaM-binding protein inhibited the activity of CaM-dependent NAD kinase and the degree of inhibition increased with augmentation of the 21-kDa protein, which appeared to be the typical characteristic of CaM-binding protein.
