Oregano Essential Oil and Purple Garlic Powder Effects on Intestinal Health, Microbiota Indicators and Antimicrobial Resistance as Feed Additives in Weaning Piglets

Finding alternatives to zinc oxide is a pressing issue for the pig production sector. We studied the impact of the bioactive components degradation of oregano essential oil (OEO) and purple garlic powder (PGP) during storage in silos, their effect on the morphometry of the jejunum and ileum and the cecal microbiota as intestinal health indicators in piglets during the post-weaning period. We also monitored antimicrobial resistance in the commensal indicator E. coli. Histological parameters and intestinal microbiota were measured in 140 piglets weaned at 21 days of age. Seven dietary treatments were used: a negative control group (basal diet), a positive control group with ZnO (3000 mg/kg of food), two groups with OEO at 0.4% and 1.2%, respectively, two groups with PGP 0.4% and 2%, respectively, and a group with OEO with 1.2% combined with PGP with 2%. Each group of piglets received the treatment for seven weeks, from weaning, before samples were taken. Antibiotic resistance profiles were measured in 81 E. coli strains. On this occasion, only the control groups, ZnO, OEO 1.2%, PGP 2% and OEO 1.2% + PGP 2% were used, and the samples were obtained from the cecal content. A progressive loss of the bioactive components of OEO and PGP was observed during the 34 days of storage (p < 0.05). PGP 2%, OEO 1.2% and their combination showed results similar to ZnO (p > 0.05), or superior in the study of intestinal morphometry and the values of E. coli and Lactobacillus. All categories showed high levels of resistance. Only the strains isolated from the OEO 1.2% group did not show resistance to colistin and presented the lowest resistance values. In general, high doses of the additives studied showed the best results, obtaining levels like or higher than those offered by ZnO

Bovine Tuberculosis in a Free Ranging Red Fox (Vulpes vulpes) from Doñana National Park (Spain)

During 1997 and 1998, a survey of Iberian carnivores was conducted to study the epidemiology of bovine tuberculosis in the Doñana National Park and surrounding areas in southwestern Spain. Post-mortem examinations were done on seven red foxes (Vulpes vulpes), two Egyptian mongoose (Herpestes ichneumon), one weasel (Mustela nivalis), two genets (Genetta genetta), one Iberian lynx (Lynx pardinus), one Eurasian badger (Meles meles), and two polecats (Mustela putorius). Lesions suggestive of bovine tuberculosis were not detected but, in culture, Mycobacterium bovis was isolated from the retropharyngeal lymph nodes of one adult male red fox. This is the first report of M. bovis infection in red fox in Spain.Peer reviewe

Experiencia clínica del tratamiento con onabotulinumtoxin A en pacientes con migraña refractaria

To analyse our experience in the treatment of refractory chronic migraine, episodic frequent refractory migraine (>= 10 days/month), with onabotulinumtoxin A (OnabotA). PATIENTS AND METHODS. Retrospective analysis of patients with refractory migraine who underwent, at least two sessions of OnabotA pericranial injections following the PREEMPT protocol between 2008 and 2012. The efficacy of OnabotA was evaluated comparing the basal situation with 12-16 weeks after the second session. We analysed the subjective improvement of the patients, number of days with headache, preventive and abortive drugs consumption, and adverse effects. RESULTS. Forty-one patients (37 women, 4 male) were identified. 65.8% patients experienced subjective improvement after OnabotA treatment. 36.58% responded (reduction of > 50% in headache days). Differences between days with headache before the first session (24.5 +/- 7.3), and 12-16 weeks after the second session (17.4 +/- 11.6), as well as the differences between the number of abortive drugs taken before the first session (26.8 +/- 23.1) and 12-16 weeks after the second session (16.7 +/- 19.3), were statistically significant (p < 0.001). Subgroups analysis showed that all differences were significant, except for the reduction of the number of days with headache in patients with episodic frequent refractory migraine. CONCLUSION. Our work shows that treatment with OnabotA is safe and useful in patients with episodic and chronic refractory migraine, including those patients with medication overuse headache

Simultaneous analysis of the elastic scattering and breakup channel for the reaction 11 Li + 208 Pb at energies near the Coulomb barrier

We present a detailed analysis of the elastic scattering and breakup channel for the reaction of Li11 on Pb208 at incident laboratory energies of 24.3 and 29.8 MeV, measured at the radioactive ion beam facility of TRIUMF, in Vancouver, Canada. A large yield of Li9 fragments was detected by four charged particle telescopes in a wide angular range. The experimental angular and energy distributions of these Li9 fragments have been compared to coupled-reaction-channel and continuum-discretized coupled-channel calculations. The large production of Li9 fragments at small angles can be explained by considering a direct breakup mechanism, while at medium-large angles a competition between direct breakup and neutron transfer to the continuum of the Pb208 target was observed.Proyecto Nacional (España) PA2009-08848 PA2009-07387 PA2010-22131-C02-01 FPA2009-07653 FPA2012-32443Programa Consolider-Ingenio 2010 (España) CSD2007-0004

Study of the scattering of halo nuclei around the Coulomb barrier

During the past ten years the present collaboration has carried out several experiments related with the study of radioactive nuclei. One of the topics in which we have centered our research, is the scattering of halo nuclei at energies around the Coulomb barrier. As part of this study, we present in this work a review of the results obtained from the scattering of 6He, 11Be and 11Li. The presence of a "halo" in these exotic nuclei is found to have a striking effect on the dynamics of these reactions, making their study an interesting experimental problem and a challenge for existing reaction theories.Ministerio de Ciencia y Tecnología FPA2005-04460, FPA2005-02379, FPA-2000-1592-C03-02, FPA2003-05958, FPA2002- 04181-C04-02/03, FPA2006-13807-c02-0, FPA2009- 07653Programa Español Consolider-Ingenio 2010 CSD2007-0004

Scattering of light halo nuclei on heavy target at energies around the coulomb barrier

INPC 2013 – International Nuclear Physics ConferenceWe report here on experiments performed at TRIUMF to study the scattering of the light halo nuclei 11Li on lead at energies below and around the Coulomb barrier. The the elastic and break-up differential cross section are interpreted in the framework of Continuum-Discretized Coupled-Channel calculations. The departure from Rutherford scattering at energies below the barrier is well beyond the behavior of normal nucleiConsejo Interinstitucional de Ciencia y Tecnología FPA2009-07387Consejo Interinstitucional de Ciencia y Tecnología FPA2012-32443Consejo Interinstitucional de Ciencia y Tecnología FPA2009-08848Consejo Interinstitucional de Ciencia y Tecnología FPA2009-07653Consejo Interinstitucional de Ciencia y Tecnología FPA2010-22131-C02-0

Influence of obstructive sleep apnea on systemic inflammation in pregnancy

Background: Obstructive sleep apnea (OSA) is prevalent in pregnancy and it is associated with adverse pregnancy-related outcomes such as gestational diabetes, pre-eclampsia, and low birth weight. Maternal systemic inflammation is proposed to be one of the main intermediate mechanisms. However, the effects of OSA on systemic inflammation are unknown in normal pregnancy. Methods: Women in the 3rd trimester underwent hospital polysomnography to evaluate whether OSA increases systemic inflammation in normal pregnancy and its potential association with adverse fetal outcomes. OSA was defined as an apnea–hypopnea index (AHI) of = 5 h-1. Plasma cytokines levels (TNF-a, IL-1ß, IL-6, IL-8, and IL-10) were determined by multiple immunoassays. Results: We included 11 patients with OSA and 22 women with AHI &lt; 5 h-1, who were homogeneous in age, and body mass index (BMI). Women with OSA had significant higher levels of TNF-a, IL-1ß, IL-8, and IL-10. We found significant correlations between AHI during REM and TNF-a (r = 0.40), IL-1ß (r = 0.36), IL-6 (r = 0.52), IL-8 (r = 0.43), between obstructive apnea index and TNF-a (r = 0.46) and between AHI and IL-1ß (r = 0.43). We also found that CT90% was related to IL-8 (r = 0.37). There were no significant differences in neonatal characteristics; however, we found inverse correlations between TNF-a and IL-8 with birth weight (both r = -0.48), while IL-8 showed a significant inverse relationship with neonatal gestational age (r = -0.48). Conclusions: OSA in our normal pregnancy population was associated with higher systemic inflammation, which was related to obstructive events, especially during REM sleep. Moreover, systemic inflammation was inversely correlated with neonatal birth weight and age

The experiment was performed at the GANIL-SPIRAL facility, with the aim of extracting information about the structure of 8He and the relevant reaction mechanisms. In this contribution, details of the experimental setup and preliminary data on elastic cross sections are reporte

Single nucleotide polymorphisms in DNA repair genes as risk factors associated to prostate cancer progression

Background Besides serum levels of PSA, there is a lack of prostate cancer specific biomarkers. It is need to develop new biological markers associated with the tumor behavior which would be valuable to better individualize treatment. The aim of this study was to elucidate the relationship between single nucleotide polymorphisms (SNPs) in genes involved in DNA repair and prostate cancer progression.Methods A total of 494 prostate cancer patients from a Spanish multicenter study were genotyped for 10 SNPs in XRCC1, ERCC2, ERCC1, LIG4, ATM and TP53 genes. The SNP genotyping was made in a Biotrove OpenArray® NT Cycler. Clinical tumor stage, diagnostic PSA serum levels, and Gleason score at diagnosis were obtained for all participants. Genotypic and allelic frequencies were determined using the web-based environment SNPator.Results SNPs rs11615 (ERCC1) and rs17503908 (ATM) appeared as risk factors for prostate cancer aggressiveness. Patients wild homozygous for these SNPs (AA and TT, respectively) were at higher risk for developing cT2b – cT4 (OR = 2.21 (confidence interval (CI) 95% 1.47 – 3.31), p < 0.001) and Gleason scores ≥ 7 (OR = 2.22 (CI 95% 1.38 – 3.57), p < 0.001), respectively. Moreover, those patients wild homozygous for both SNPs had the greatest risk of presenting D’Amico high-risk tumors (OR = 2.57 (CI 95% 1.28 – 5.16)).Conclusions Genetic variants at DNA repair genes are associated with prostate cancer progression, and would be taken into account when assessing the malignancy of prostate cancer.This work was subsidized by a grant from the Instituto de Salud Carlos III (Ministerio de Economía y Competitividad from Spain), ID: PI12/01867.
