Energy intake effects at pasture on milk production and coagulation properties in girgentana goats with different as1-cn genotypes
2007
The aim of this study was to investigate whether proerties of milk from Girgentana goats of different as1-CN genotypes were affected by the energy intake at pasture. Thirty six goats were genotyped at as1-CN locus using several genomic techniques and milk protein analysis. Eight genotypes associted with low (FF, 2 goats), medium (AF, AN, BF, BN, 21 goats) and high (AA, AB, BB, 13 goats) as1-CN level have beed typed. The increase in energy intake (E) of goats from low (2.0 Mcal/d) corresponded to an increasing dry matter intake, diet CP percentage, milk yield and clotting parameters, and a reduction in milk fat. Depending on genotypes linked to increasign as1-CN, milk was higher in casein, c…
Feed intake, milk composition and cheesemaking properties in Girgentana grazing goats with different genotype at αs1-casein and K-casein
2009
Milk ability for cheese manufacturing depends on both animals utilization of dietary nutrients and genetic polymorphism of caseins. It is well known that strong alleles associated with high content of as1-casein increase cheese-making properties of goat milk, whereas there is little information about effect of genetic variants of κ-casein. The aim of this experiment was to investigate the effect of some composite as1-casein and κ-casein genotypes n changing feeding behavior at pasture and milk yield and properties of Girgentana goats. Forty goats were genotyped at as1, as2, b and κ-casein loci using specific PCR protocols at DNA level and IEF technique at milk protein level. Twelve goats, d…
Emerging Immnunohistochemical evidence for Direct Peripheral Control of Endocannabinoids on the Gastrointestinal Tract and Pancreas of Obese (fa/fa)a…
2012
This research has the objective to investigate immunohistochemical expression of CB1 receptor and its probable changes in Gastroenteropancreatic system (GEP) of obese and lean Zucker rats and understand the endocannabinoid pathophysiological implications in the obesity. Male obese (fa/fa) and lean Zucker rats 6 weeks old were obtained from Harlan Italy Srl; the rats were sacrificed at 8, 12 and 16 weeks old. Normal rats also were sacrificed. Specimens of stomach, jejunum-ileum and pancreas were fixed in Bouin’s mixture and embedded in paraffin; obtained sections were processed with anti-CB1 (Biosource Europe SA) by Streptavidin-Biotin-Complex Method. The findings show that CB1 receptor is e…
Calcium intake in the Mediterranean region
2014
A deficiency in calcium intake, is considered an important risk factor for the development of osteoporosis. Since the human body cannot produce calcium, individuals are recommended to maintain an adequate daily intake. The aim of the “Calcium Intake in the Mediterranean Region” Study is to evaluate the mean calcium intake in men and women between 40 and 80 residing in various areas of the Mediterranean basin. Enrolled subjects have been asked to fill out a self-administered questionnaire to evaluate the mean daily calcium intake from food, principle risk factors for osteoporosis were registered. A dual- energy X-ray absorptiometry (DEXA) has also been carried out to evaluate bone mineral de…
Jejunoileal bypass as the main procedure in the onset of immune-related conditions: the model of BADAS
2013
Bariatric surgery represents a common approach for the control of severe morbid obesity, reducing caloric intake by modifying the anatomy of the gastrointestinal tract. Following jejunoileal bypass, a large spectrum of complications has been described, with rheumatic manifestation present in up to 20% of cases. Although bowel bypass syndrome, also called blind loop syndrome, is a well-recognized complication of jejunoileal bypass, the same syndrome was recognized in patients who had not had intestinal bypass surgery, and the term the 'bowel-associated dermatosis-arthritis syndrome' (BADAS) was coined. The pathogenesis of BADAS is as yet poorly understood and only few data concerning this is…
Purification of recovered phosphoric acid by extracting aluminium with di-2-ethylhexyl phosphoric acid
2021
AbstractThe extraction of aluminium from dilute phosphoric acid with di-2-ethylhexyl phosphoric acid (DEHPA) was optimized using response surface methodology. The optimization was based on the experimental three-level central composite face-centred design (CCF) and was conducted on real-life samples. The three variables included were pH, extractant concentration and aqueous to organic phase ratio (AO). Under the optimized conditions (pH 2.5, 0.6 M DEHPA and AO ratio 1:2), extraction efficiency of 99% for aluminium in four extraction stages is achieved. The purified phosphoric acid solution can then be utilized by the fertilizing industry. Stripping tests for organic phase loaded with alumin…
Toxicological assessment of mesoporous silica particles in the nematode Caenorhabditis elegans
2018
[EN] Here we report the toxicological evaluation of mesoporous silica particles (MSPs) in the nematode C. elegans. Specifically, we have investigated the effect of bare micro- (M0) and nano-sized (N0) MSPs, and their corresponding functionalized particles with a starch derivative (Glu-N) (M1 and N1, respectively) on C. elegans ageing parameters. The toxicity of MSPs, their impact on C. elegans lifespan, movement capacity, progeny and ability to survive upon exposure to acute oxidative stress were assessed. This study demonstrated that both size particles assayed (M0 and N0), labeled with rhodamine and monitored through fluorescence microscopy, are ingested by the nematode. Moreover, toxicit…
Assessment of test-meal induced autonomic arousal in anorexic, bulimic and control females
1998
This study attempted to measure three different physiological responses to food intake in eating disordered subjects. Skin conductance level (SCL), heart rate and electroencephalogram were recorded before, during and after a test-meal in 42 females (14 anorexic inpatients, 10 bulimic outpatients and 18 control subjects). Significant increase in SCL during the meal was found in anorexics only. Pre-meal SCL was lower in bulimics than in controls and anorexics. No changes were found on heart rate or electroencephalogram in all groups of subjects. This suggests that anorexic inpatients may display a measurable arousal when confronted with a meal, whereas bulimic outpatients and control subjects…

Preliminary Estimation of Deoxynivalenol Excretion through a 24 h Pilot Study
2015
A duplicate diet study was designed to explore the occurrence of 15 Fusarium mycotoxins in the 24 h-diet consumed by one volunteer as well as the levels of mycotoxins in his 24 h-collected urine. The employed methodology involved solvent extraction at high ionic strength followed by dispersive solid phase extraction and gas chromatography determination coupled to mass spectrometry in tandem. Satisfactory results in method performance were achieved. The method"s accuracy was in a range of 68%108%, with intra-day relative standard deviation and inter-day relative standard deviation lower than 12% and 15%, respectively. The limits of quantitation ranged from 0.1 to 8 μg/Kg. The matrix effect w…
