Strategie alimentari atte a incrementare il contenuto di Omega3 e CLA del latte

Tra i componenti naturali biologicamente attivi, e con cui è possibile arricchire il latte, notevole importanza rivestono gli acidi grassi Omega3 e i CLA. I ruoli benefici svolti da questi particolari lipidi si manifestano soprattutto nella regolazione dei processi infiammatori, nella prevenzione del diabete e delle malattie cardiovascolari; è inoltre dimostrato come i CLA abbiano attività anticancerogena e ipocolesterolemica, stimolino il sistema immunitario e prevengano l’insorgenza del diabete e delle malattie croniche non trasmissibili. Lo scopo di questo lavoro è stato quello di individuare, in condizioni sperimentali controllate e nelle comuni realtà di allevamento, le possibili strategie alimentari atte ad aumentare le concentrazioni di Omega-3 e CLA del latte vaccino, senza penalizzare i titoli di grasso del latte. I lavori sperimentali effettuati possono essere distinti in 3 fasi: una prima fase in cui l’oggetto principale delle ricerche svolte è stato l’incremento in acidi grassi Omega3 del latte, una seconda fase in cui l’obiettivo si è allargato anche all’incremento delle concentrazioni in CLA, e una terza fase che ha avuto come scopo quello di incrementare i livelli di Omega3 e CLA del latte senza penalizzare i titoli di grasso. Le strategie alimentari più efficaci si sono basate sulla modificazione degli apporti lipidici della razione attraverso la supplementazione con seme di soia o relativo olio, semi di lino o relativo olio, olii di pesce e acido stearico. Le ricerche svolte hanno evidenziato come, attraverso opportune ed accurate modulazioni degli apporti lipidici delle razioni, sia di fatto possibile innalzare i contenuti di acidi grassi della serie Omega3 e CLA nel latte vaccino, senza penalizzare i titoli del grasso del latte.

A Qualitative Study on the Adoption of Copyright Assignment Agreements (CAA) and Copyright License Agreements (CLA) within Selected FOSS Projects

Open source software projects are multi-collaborative works incorporating the contributions of numerous developers who, in spite of publishing their code under a public license such as GPL, Apache or BSD, retain the copyright in their contributions. Having multiple copyright-owners can make the steering of a project difficult, if not impossible, as there is no ultimate authority able to take decisions relating to the maintenance and use of the project. This predicament can be remedied by centring the dispersed copyrights in a single authority via contributor agreements. Whether to introduce contributor agreements, and if so in which form, is a pressing question for many emerging, but also for established projects. The current paper provides an insight into the ethos of different projects and their reason for adopting or rejecting particular contributor agreements. It further examines the exact set-up of the contributor agreements used and concludes that smart drafting can blur the difference between CAAs and CLAs to a considerable extent, manoeuvring them into a legal grey area. To avoid costly litigation to test the legal enforceability of individual clauses, this paper proposes the establishment of an international committee comprised of developers, product managers and lawyers interested in finding a common terminology that may serve as a foundation for every contributor agreement

Effects of Feeding Calcium Salts of Conjugated Linoleic Acid (CLA) to Finishing Steers

Thirty crossbred steers were randomly assigned to three treatment groups and fed corn-based finishing diets (88% concentrate) containing 0, 1.0 or 2.5% conjugated linoleic acid (CLA) for an average of 130 days. Steers fed 2.5% CLA consumed less feed and had lower daily gains than control steers. Carcass weights tended to be reduced, and marbling scores were decreased by feeding 2.5% CLA. There were no significant effects of feeding CLA on dressing percentages, yield grades and backfat measurements. The rounds from each animal were physically separated into tissue components. Rounds from steers fed CLA contained a higher percentage of lean tissue and a lower percentage of fat. Feeding CLA increased concentrations of CLA in lipids from fat and lean in rib steaks and rounds. Increasing CLA in beef had no effects on shelf life, tenderness, juiciness, flavor or flavor intensity of rib steaks. Although results indicated that feeding calcium salts of CLA to beef steers decreased performance, concentrations of CLA in tissues could be increased offering the availability of a leaner, more healthful meat product.

Effects Of Therapeutic Approach On The Neonatal Evolution Of Very Low Birth Weight Infants With Patent Ductus Arteriosus.

To analyze the effects of treatment approach on the outcomes of newborns (birth weight [BW] < 1,000 g) with patent ductus arteriosus (PDA), from the Brazilian Neonatal Research Network (BNRN) on: death, bronchopulmonary dysplasia (BPD), severe intraventricular hemorrhage (IVH III/IV), retinopathy of prematurity requiring surgical (ROPsur), necrotizing enterocolitis requiring surgery (NECsur), and death/BPD. This was a multicentric, cohort study, retrospective data collection, including newborns (BW < 1000 g) with gestational age (GA) < 33 weeks and echocardiographic diagnosis of PDA, from 16 neonatal units of the BNRN from January 1, 2010 to Dec 31, 2011. Newborns who died or were transferred until the third day of life, and those with presence of congenital malformation or infection were excluded. Groups: G1 - conservative approach (without treatment), G2 - pharmacologic (indomethacin or ibuprofen), G3 - surgical ligation (independent of previous treatment). Factors analyzed: antenatal corticosteroid, cesarean section, BW, GA, 5 min. Apgar score < 4, male gender, Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE II), respiratory distress syndrome (RDS), late sepsis (LS), mechanical ventilation (MV), surfactant (< 2 h of life), and time of MV. death, O2 dependence at 36 weeks (BPD36wks), IVH III/IV, ROPsur, NECsur, and death/BPD36wks. Student's t-test, chi-squared test, or Fisher's exact test; Odds ratio (95% CI); logistic binary regression and backward stepwise multiple regression. Software: MedCalc (Medical Calculator) software, version 12.1.4.0. p-values < 0.05 were considered statistically significant. 1,097 newborns were selected and 494 newborns were included: G1 - 187 (37.8%), G2 - 205 (41.5%), and G3 - 102 (20.6%). The highest mortality was observed in G1 (51.3%) and the lowest in G3 (14.7%). The highest frequencies of BPD36wks (70.6%) and ROPsur were observed in G3 (23.5%). The lowest occurrence of death/BPD36wks occurred in G2 (58.0%). Pharmacological (OR 0.29; 95% CI: 0.14-0.62) and conservative (OR 0.34; 95% CI: 0.14-0.79) treatments were protective for the outcome death/BPD36wks. The conservative approach of PDA was associated to high mortality, the surgical approach to the occurrence of BPD36wks and ROPsur, and the pharmacological treatment was protective for the outcome death/BPD36wks.
