[Q]: Context: A functional vacuolar adenosine triphosphatase (v-ATPase) complex regulates canonical Wnt/-catenin signaling. The goal of this study was to identify the distribution of the v-ATPase in human and murine models of pancreatic intraepithelial neoplasms (PanINs) and assess its role in Wnt/-catenin signaling.', 'We evaluated the immunolabeling pattern of the v-ATPase in human PanIN specimens and murine PanIN-1 and PanIN-2 lesions obtained from Ptf1a(Cre/+); LSL-Kras(G12D) mice. Wnt/-catenin signaling was interrogated in primary PanIN cells by examining the phosphorylated levels of its surface coreceptor, low-density lipoprotein receptor-related protein-6 (LRP6), and its intracellular effector, nonphosphorylated -catenin. The response of primary PanIN cells to epidermal growth factor (EGF) was assessed in the absence and presence of the v-ATPase inhibitor, concanamycin.', 'In advanced (PanIN-2), but not early (PanIN-1), lesions, the v-ATPase assumed a polarized phenotype. Blocking the v-ATPase disrupted Wnt/-catenin signaling in primary PanIN cells despite significantly higher levels of the total and activated Wnt cell surface coreceptor, LRP6. Vacuolar adenosine triphosphatase blockade significantly decreased the total and activated levels of EGF receptor, a determinant of PanIN progression. The activation of EGF receptor and its intracellular mediator, p44/42 mitogen-activated protein kinase, was also reduced by v-ATPase blockade. This led to diminished proliferation in response to EGF ligand.
Answer: The v-ATPase regulates Wnt/-catenin and EGF receptor signaling in PanINs.

[Q]: Context: the nutritional content and energy density of foods is related to greater control of appetite, satiety and reducing food intake.', 'the randomized crossover study included 20 healthy women, aged 20 and 30 years with a BMI of 20 to 24.9 kg/m2 and who completed that included 3 day trial comparing 8 hours 130 kcal snacks consumed afternoon: yoghurt with added whey protein (PSL), biscuits and chocolate. Participants consumed a standardized menu; snack was consumed 3 hours after lunch. Perceived hunger and fullness were evaluated during the afternoon until dinner voluntary intake ad libitum. They repeat the same snack 3 times.', 'consumption of yogurt with PSL led to a further reduction of appetite in the afternoon in front of the snack of chocolate and biscuits (p < 0.001). No differences of appetite in the afternoon between chocolate vs cookies but significant difference between yogurt with PSL and other treatments (p < 0.001) were detected. At snack, yogurt there was a significant reduction in caloric intake compared to other snacks (p < 0.001) and a later request for dinner with about 45 minutes apart.
Answer: snacks with less energy density and rich in protein (yogurt with PSL) improve the control of appetite, satiety and reduces food intake in healthy women later.

[Q]: Context: According to previous studies, sulodexide suppresses intravascular inflammation when used in patients with chronic venous disease (CVD). In the current study, we tested the effect of prolonged in vitro exposure of human venous endothelial cells to the serum from patients with CVD, examining the function of these cells and how it is modified when these cells are simultaneously exposed to sulodexide.', 'Human umbilical venous cells (HUVEC) were cultured in standard medium (control), in medium supplemented with 5% serum pooled from CVD patients (CVD-serum) or in medium from CVD patients who were treated with sulodexide (CVD-serum-SUL). The synthesis of interleukin-6 (IL-6), monocyte chemoattractant protein -1(MCP-1) and soluble intercellular adhesion molecule - 1 (s-ICAM-1) were studied at the beginning of incubation and were measured after 9 and 15 days of exposure to the studied media. The concentration of IL-6 after cell stimulation by interleukin -1 (IL-1) was also measured. In a subsequent part of the experiment, the effect of the studied sera on the in vitro replicative ageing of HUVEC was evaluated. A total of 15 passages of the cell culture were performed and both the PDT (population doubling time) and the cell hypertrophy were assessed.', 'The concentrations of Il-6, MCP-1, and ICAM-1 gradually increased in the supernatants containing 5% CVD serum compared with the control medium. In the supernatants obtained after cell incubation with serum from sulodexide treated patients, the increase in concentrations of IL-6, MCP-1 and ICAM-1 was significantly less than the control. Release of IL-6 after stimulation with IL-1 (100 pg/mL) was the highest in the CVD-serum group: 3540670 pg/105 cells vs. 1850540 pg/105 cells in the control (P<0.01 vs. CVD-serum) and 2320 430 pg/105 cells in CVD-serum-SUL (P<0.02 vs. CVD-serum). PDT was significantly longer in the cells incubated with CVD serum compared with the control group, and PDT was reduced when serum from sulodexide treated patients was used. The cells became senescent in the presence of CVD serum, but the cells obtained from patients at the end of 8 weeks of treatment with sulodexide showed a much weaker inflammatory phenotype than the CVD group.
Answer: Chronic in vitro exposure of HUVEC to medium supplemented with CVD patient serum induces an inflammatory phenotype. Sulodexide treatment significantly reduces that effect and slows HUVEC senescence in the milieu of CVD serum.
