Non-alcoholic fatty pancreas disease pathogenesis: a role for developmental programming and altered circadian rhythms.
2013
Objectives Emerging evidence suggests that maternal obesity (MO) predisposes offspring to obesity and the recently described non-alcoholic fatty pancreas disease (NAFPD) but involved mechanisms remain unclear. Using a pathophysiologically relevant murine model, we here investigated a role for the biological clock - molecular core circadian genes (CCG) in the generation of NAFPD. Design Female C57BL6 mice were fed an obesogenic diet (OD) or standard chow (SC) for 6 weeks, prior to pregnancy and throughout gestation and lactation: resulting offspring were subsequently weaned onto either OD (Ob_Ob and Con_Ob) or standard chow (Ob_Con and Con_Con) for 6 months. Biochemical, pro-inflammatory and…
Distribución, solapamiento y características nosológicas de los trastornos abdominales funcionales en una muestra de población pediátrica en base a l…

En los últimos 25 años se han multiplicado los estudios relacionados con las aplicaciones de la Lógica Difusa en Medicina, si bien en Pediatría este incremento es aún vestigial. Por otro lado, la práctica totalidad de los mismos está relacionada con la Ingeniería y no con el modelado mediante Lógica Difusa de aspectos clínicos. Recientemente se desarrolló una amplia investigación sobre las aplicaciones de la Lógica Difusa en la toma de decisiones clínicas en relación con infecciones del tracto respiratorio inferior en Pediatría. En base a los resultados prometedores de dicho estudio consideramos conveniente explorar otros aspectos clínicos, como son el proceso de diagnóstico médico, la natu…
Unusual basement layer in the midgut of gammaridean Niphargus virei Chevreux (Crustacea, Amphipoda).
1988
The basement membrane of the midgut and posterior caeca epithelium in the gammaridean amphipod Niphargus virei Chevreux, 1896 is made of an unusual structure. This basal lamina, properly called “basal layer”, shows a dense sheet formed by a system of dense hexagonal plates connected by thin filaments. Histochemical studies and enzymatic reactions lead to the conclusion that these structures are proteinaceous, without collagenous protein, and embedded in a neutral polysaccharide matrix. The possible mechanical significance of these mesenteric structures is discussed.
HSP10,HSP70 AND HSP90 IMMUNOHISTOCHEMICAL LEVELS CHANGE IN ULCERATIVE COLITIS AFTER THERAPY
2011
Ulcerative colitis (UC) is a form of inflammatory bowel disease (IBD) characterized by damage of large bowel mucosa and frequent extra-intestinal autoimmune comorbidities. The role played in IBD pathogenesis by molecular chaperones known to interact with components of the immune system involved in inflammation is unclear. We previously demonstrated that mucosal Hsp60 decreases in UC patients treated with conventional therapies (mesalazine, probiotics), suggesting that this chaperonin could be a reliable biomarker useful for monitoring response to treatment, and that it might play a role in pathogenesis. In the present work we investigated three other heat shock protein/molecular chaperones:…
Activation of Human Osteoblasts via Different Bovine Bone Substitute Materials With and Without Injectable Platelet Rich Fibrin in vitro
2021
IntroductionThe aim of the in vitro study was to compare the effect of four bovine bone substitute materials (XBSM) with and without injectable platelet-reach fibrin for viability and metabolic activity of human osteoblasts (HOB) as well as expression of alkaline phosphatase (ALP), bone morphogenetic protein 2 (BMP-2), and osteonectin (OCN).Materials and MethodsCerabone® (CB), Bio-Oss® (BO), Creos Xenogain® (CX) and MinerOss® X (MO) ± i-PRF were incubated with HOB. At day 3, 7, and 10, cell viability and metabolic activity as well as expression of ALP, OCN, and BMP-2, was examined.ResultsFor non-i-PRF groups, the highest values concerning viability were seen for CB at all time points. Pre-t…
Gandhian Fasting and Cultural Indigestion in Jeffrey Eugenides’ “Air Mail”
2020
Abstract “Air Mail” is one of the ten stories included in Jeffrey Eugenides’ latest collection of stories, Fresh Complaint. Drawing on one of the characters in his third novel, The Marriage Plot, as well as on his own experiences in India working as a volunteer alongside Mother Theresa, “Air Mail” tells the story of young (and idealistic) Mitchell Grammaticus, who leaves the West in order to explore India, Bangkok, and a tropical island in the Gulf of Siam, where he finally succumbs to dysentery (as well as to thoughts regarding the futility of existence). Ripe in irony and biting sarcasm, coupled with a surprising tenderness and empathy, which are the landmarks of Eugenides’ writing, the s…
SELF-EXPANDABLE METAL STENT PLACEMENT FOR CLOSURE OF A LEAK AFTER TOTAL GASTRECTOMY FOR GASTRIC CANCER: REPORT ON THREE CASES AND REVIEW OF THE LITER…
2014
In the setting of the curative oncological surgery, the gastric surgery is exposed to complicated upper gastrointestinal leaks, and consequently the management of this problem has become more critically focused than was previously possible. We report here three cases of placement of a partially silicone-coated SEMS (Evolution Controlled Release Esophageal Stent System, Cook Medical, Winston-Salem, NC, USA) in patients who underwent total gastrectomy with Roux-en-Y end-to-side esophagojejunostomy for a gastric adenocarcinoma. The promising results of our report, despite the small number of patients, suggest that early stenting (through a partially silicone-coated SEMS) is a feasible alternat…
Experimental study of the anaerobic urban wastewater treatment in a submerged hollow-fibre membrane bioreactor at pilot scale
2011
The aim of this study was to assess the effect of several operational variables on both biological and separation process performance in a submerged anaerobic membrane bioreactor pilot plant that treats urban wastewater. The pilot plant is equipped with two industrial hollow-fibre ultrafiltration membrane modules (PURON¿ Koch Membrane Systems, 30m 2 of filtration surface each). It was operated under mesophilic conditions (at 33°C), 70days of SRT, and variable HRT ranging from 20 to 6h. The effects of the influent COD/SO 4-S ratio (ranging from 2 to 12) and the MLTS concentration (ranging from 6 to 22gL -1) were also analysed. The main performance results were about 87% of COD removal, efflu…
Monofloral honeys by Sicilian black honeybee (Apis mellifera ssp. sicula) have high reducing power and antioxidant capacity
2016
Thirty samples from thirteen Sicilian monofloral honeys by the local black honeybee, and two honeydew honeys, were studied to assess phenol content, reducing power and antioxidant capacity as well as correlations among these parameters. Honeys from Apiaceae showed the highest phenol amount and capacity to reduce ferric ion and stable chemical radicals, whereas honeys from Leguminosae the lowest. All honeys were active against myoglobin-derived radicals usually formed in red meat after storage and/or heating and significant correlation (p = 0.023) was found between flavonoid content and deactivation rate of this radical.

MUC1-CT mediates corticosteroid responses in COPD
2016
Background: Corticosteroid resistance is an acquired condition in chronic obstructive pulmonary disease (COPD) patients and a challenge to develop new anti-inflammatory therapies. In previous reports we showed that cytoplasmic tail of the membrain tethered mucin 1 (MUC1-CT) interacts with glucocorticoid receptor (GR) mediating corticosteroid anti-inflammatory efficacy. Objectives: To analyze the role of MUC1-CT as a key marker of corticosteroid efficacy in COPD Methods: The expression of MUC1-CT and the anti-inflammatory role of dexamethasone were evaluated in neutrophils and bronchial epithelial cells from healthy and COPD patients. Anti-inflammatory effects of dexamethasone and glucocorti…
