Question: Lieber-DeCarli diet has been used to induce obesity and non-alcoholic steatohepatitis (NASH). As scarce anatomical and clinical-related information on this diet model exists and being exercise an advised strategy to counteract metabolic diseases, we aimed to analyze the preventive (voluntary physical activity - VPA) and therapeutic (endurance training - ET) effect of exercise on clinical/anatomical features of rats fed with Lieber-DeCarli diet.', 'In the beginning of the protocol, Sprague-Dawley rats were divided into standard-diet sedentary (SS, n = 20), standard-diet VPA (SVPA, n = 10), high-fat diet sedentary (HS, n = 20) and high-fat diet VPA (HVPA, n = 10) groups. After 9-weeks, half (n = 10) of SS and HS groups were engaged in an ET program (8 wks/5 d/wk/60 min/day). At this time, a blood sample was collected for biochemical analysis. At the end of protocol (17-weeks) anatomic measures were assessed. Heart, liver, femur and visceral fat were weighted and blood was collected again. Liver section was used for histopathological examination.', 'At 17-weeks, high-fat diet increased visceral adiposity (HS vs. SS), which was counteracted by both exercises. However, ET was the only intervention able to diminished obesity-related measures and the histological features of NASH. Moreover, blood analysis at 9 weeks showed that high-fat diet increased ALT, AST, cholesterol and HDL while VLDL and TG levels were decreased (HS vs. SS). Notably, although these parameters were counteracted after 9-weeks of VPA, they were transitory and not observed after 17-weeks.

Answer: Does physical exercise antagonize clinical and anatomical features characterizing Lieber-DeCarli diet-induced obesity and related metabolic disorders?


Question: Crowdsourcing dietary ratings for food photographs, which uses the input of several users to provide feedback, has potential to assist with dietary self-monitoring.', "This study assessed how closely crowdsourced ratings of foods and beverages contained in 450 pictures from the Eatery mobile app as rated by peer users (fellow Eatery app users) (n = 5006 peers, mean 18.4 peer ratings/photo) using a simple 'healthiness' scale were related to the ratings of the same pictures by trained observers (raters). In addition, the foods and beverages present in each picture were categorized and the impact on the peer rating scale by food/beverage category was examined. Raters were trained to provide a 'healthiness' score using criteria from the 2010 US Dietary Guidelines.", "The average of all three raters' scores was highly correlated with the peer healthiness score for all photos (r = 0.88, p<0.001). Using a multivariate linear model (R(2) = 0.73) to examine the association of peer healthiness scores with foods and beverages present in photos, peer ratings were in the hypothesized direction for both foods/beverages to increase and ones to limit. Photos with fruit, vegetables, whole grains, and legumes, nuts, and seeds (borderline at p = 0.06) were all associated with higher peer healthiness scores, and processed foods (borderline at p = 0.06), food from fast food restaurants, refined grains, red meat, cheese, savory snacks, sweets/desserts, and sugar-sweetened beverages were associated with lower peer healthiness scores.

Answer: Are the use of crowdsourcing for dietary self-monitoring : crowdsourced ratings of food pictures comparable to ratings by trained observers?


Question: House dust mites (HDM) have been shown to be important sources of indoor allergens associated with asthma and other allergic conditions. While exogenous proteases from allergens have a direct proinflammatory role in the respiratory tract, the precise mechanisms underlying the release of cytokines from the respiratory epithelium are unclear.', 'The present study examines that extracellular signal-regulated kinase (ERK) activated downstream of the Ca(2+)-sensitive tyrosine kinase plays an important role in the efficient activation of the HDM-induced IL-8 signaling pathway.', 'We examined the effect of HDM, and the role of the Ca(2+)/calmodulin system and mitogen-activated protein kinases, on IL-8 expression in human lung epithelial cells.', 'In H292 cells, HDM induced IL-8 release in a time- and/or dose-dependent manner. This IL-8 release was abolished by treatment with intracellular Ca(2+) chelator (BAPTA-AM), but not by EGTA or nifedipine. Calmodulin inhibitor (calmidazolium) and tyrosine kinase inhibitor (genistein) almost completely blocked IL-8 release by HDM. PD98,059, an ERK pathway inhibitor, completely abolished HDM-induced IL-8 release. Moreover, PD98,059, BAPTA-AM, calmidazolium and genistein suppressed the HDM-induced ERK phosphorylation.

Answer:
Does calcium-calmodulin mediate house dust mite-induced ERK activation and IL-8 production in human respiratory epithelial cells?
