Nitric oxide (NO) plays a pivotal role in integrating dopamine transmission in the basal ganglia and has been implicated in the pathogenesis of Parkinson disease (PD). The objective of this study was to ascertain whether the NO synthase inhibitor, 7-nitroindazole (7-NI), is able to reduce L-DOPA-induced dyskinesias (LIDs) in a non-human primate model of PD chronically intoxicated with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Six Parkinsonian macaques were treated daily with L-DOPA for 3-4 months until they developed LIDs. Three animals were then co-treated with a single dose of 7-NI administered 45 min before each L-DOPA treatment. Dyskinetic MPTP-treated monkeys showed a significant decrease in LIDs compared with their scores without 7-NI treatment (p < 0.05). The anti-Parkinsonian effect of L-DOPA was similar in all three monkeys with and without 7-NI co-treatment. This improvement was significant with respect to the intensity and duration of LIDs while the beneficial effect of L-DOPA treatment was maintained and could represent a promising therapy to improve the quality of life of PD patients.

El hematoma hepático subcapsular espontáneo (HHSE) en gestantes, con o sin historia previa de preeclampsia, eclampsia o síndrome HELLP, es una enfermedad poco frecuente durante la gestación y el puerperio (1/45.000-1/225.000 embarazos). Su importancia para el anestesiólogo radica en que asocia una elevada morbimortalidad materna (60-86% y 39%) y neonatal (42%). Tras la sospecha clínica, el diagnóstico de certeza se establece mediante diversas pruebas de imagen; sin embargo, en la mayoría de los casos el diagnóstico del HHSE es un hallazgo casual intraoperatorio asociado a un compromiso materno o fetal. Hoy en día la actuación obstétrica y anestésica ante un HHSE no está estandarizada y depende de su integridad, la estabilidad hemodinámica materna, así como el periodo gestacional en el momento del diagnóstico. La posibilidad de una hemorragia aguda crítica con necesidad de transfusión masiva hace recomendable disponer de protocolos actualizados del tratamiento de la hemorragia obstétrica, adecuándolos a las peculiaridades clínicas de estas pacientes. Tras la fase aguda se debe prestar atención a las complicaciones tromboembólicas.(AU)
Spontaneous subcapsular hepatic hematoma (SSHH) with or without previous history of preeclampsia and/or HELLP syndrome represents a very rare pathological condition in pregnancy and postpartum (1/45,000-1/225,000 pregnancies). Its importance for the anesthesiologist lays in its association with high morbidity and mortality for the mother (60-86%, 39%) and newborn (42%). After a high clinical suspicion, the certainty clinical diagnosis is settled by different imaging techniques. However, in most cases the diagnosis of SSHH is a casual intraoperative finding associated to a maternal or fetal compromise. Nowadays the obstetric and anesthetic management of a SSHH is not standardized and depends on its integrity, hemodynamic stability and the gestational period when diagnosed. The possibility of an acute critic hemorrhage with necessity of massive transfusion, makes advisable to provide updated protocols for the treatment of obstetric hemorrhage, adapting them to the clinical peculiarities of these patients. After the acute phase, close attention should be kept on thromboembolic complications.(AU)

RESUMEN
Telemedicine is a very useful tool and resource for medical diagnosis and treatment. Since its inception in the 70s it has developed progressively, demonstrating the clinical benefit it brings to patients and being increasingly present in the daily activities of clinicians. Different studies have tried to define and limit its effectiveness at the time of application versus face-to-face assistance, this being an important variable to clarify. This article reviews the different variables that have been coined to define the effectiveness when trying to demonstrate the cost-effectiveness of including telemedicine in daily healthcare activity

Different cellular mechanisms have been described as being potentially involved in the progression of neurodegeneration in Parkinson's disease, although their role is still unclear. The present study aimed to identify in detail, through differentially expressed genes analysis by bioinformatics approaches, the molecular mechanisms triggered after a systemic insult in parkinsonian mice. To address this objective, we combined a dextran sodium sulfate (DSS)-induced ulcerative colitis experimental mice model with an acute 1-methyl-4-phenyl-1,2,3,6-tetradropyridine (MPTP) intoxication. The animals were divided into four experimental groups based on the different treatments: (i) control, (ii) DSS, (iii) MPTP and (iv) MPTP + DSS. The data obtained by microarray and functional enrichment analysis point out the implication of different molecular mechanisms depending on the experimental condition. We see, in the striatum of animals intoxicated only with DSS, dysfunction processes related to the blood. On the other hand, oxidative stress processes are more prominent at the MPTP intoxicated mice. Finally, differentially expressed genes within the MPTP + DSS show functional enrichment in inflammation and programmed cell death. Interestingly, we identify a significant synergistic negative effect of both toxins since the expression of differentially expressed genes (DEGs) related to balanced cellular homeostasis was not enough to prevent processes associated with cell death. This work provides detailed insights into the involvement of systemic inflammation, triggered after an insult in the colon, in the progression of the degeneration in Parkinsonism. In this way, we will be able to identify promising therapeutic targets that prevent the contribution of inflammatory processes in the progression of Parkinson's disease.

The population of Spanish sheep has decreased from 24 to 15 million heads in the last 75 years due to multiple social and economic factors. Such a demographic reduction might have caused an increase in homozygosity and inbreeding, thus limiting the viability of local breeds with excellent adaptations to harsh ecosystems. The main goal of our study was to investigate the homozygosity patterns of 11 Spanish ovine breeds and to elucidate the relationship of these Spanish breeds with reference populations from Europe, Africa and the Near East. By using Ovine SNP50 BeadChip data retrieved from previous publications, we have found that the majority of studied Spanish ovine breeds have close genetic relatedness with other European populations; the one exception is the Canaria de Pelo breed, which is similar to North African breeds. Our analysis has also demonstrated that, with few exceptions, the genomes of Spanish sheep harbor fewer than 50 runs of homozygosity (ROH) with a total length of less than 350 Mb. Moreover, the frequencies of very long ROH (>30 Mb) are very low, and the inbreeding coefficients (FROH ) are generally small (FROH < 0.10), ranging from 0.008 (Rasa Aragonesa) to 0.086 (Canaria de Pelo). The low levels of homozygosity observed in the 11 Spanish sheep under analysis might be due to their extensive management and the high number of small to medium farms.

The goal of the current study is to analyse the gene expression profile of the ovine skeletal muscle as well as to characterize the genetic variation of transcripts expressed in such tissue. This aim has been achieved by sequencing the longissimus dorsi transcriptomes of 50 sheep distributed in five pools representing the Canaria de Pelo, Roja Mallorquina, Gallega, Xisqueta and Ripollesa Spanish autochthonous breeds. Approximately, 363 million reads per pool have been produced and 71.9-82.9% have been successfully mapped to the ovine genome in a paired-end mode (2 × 75 bp). The 200 most expressed muscle transcripts (≈1% of the total transcript count) account for 51% (Canaria de Pelo) to 67% (Gallega) of the total ovine skeletal muscle mRNA expression. These highly expressed genes play key roles in pathways related with striated muscle contraction, gluconeogenesis, glycolysis, citric acid cycle and respiratory electron transport. RNA-Sequencing of muscle transcripts has also revealed that ~72% of the SNPs detected with this approach are shared by at least two pools, and 10% of them segregate in the five pools under analysis. Most of the substitutions detected by RNA-Seq are synonymous or missense and only a minority are predicted to have consequences on protein function.

The goals of the current work were to analyse the population structure of 11 Spanish ovine breeds and to detect genomic regions that may have been targeted by selection. A total of 141 individuals were genotyped with the Infinium 50 K Ovine SNP BeadChip (Illumina). We combined this dataset with Spanish ovine data previously reported by the International Sheep Genomics Consortium (N = 229). Multidimensional scaling and Admixture analyses revealed that Canaria de Pelo and, to a lesser extent, Roja Mallorquina, Latxa and Churra are clearly differentiated populations, while the remaining seven breeds (Ojalada, Castellana, Gallega, Xisqueta, Ripollesa, Rasa Aragonesa and Segureña) share a similar genetic background. Performance of a genome scan with BayeScan and hapFLK allowed us identifying three genomic regions that are consistently detected with both methods i.e. Oar3 (150-154 Mb), Oar6 (4-49 Mb) and Oar13 (68-74 Mb). Neighbor-joining trees based on polymorphisms mapping to these three selective sweeps did not show a clustering of breeds according to their predominant productive specialization (except the local tree based on Oar13 SNPs). Such cryptic signatures of selection have been also found in the bovine genome, posing a considerable challenge to understand the biological consequences of artificial selection.

The article is a summary of Dra. Carmen Gómez Candela's presentation at the Science in Nutrition 3rd International Congress in Milan, March 2014. The article covers omega-3 fatty acids use in different medical areas and several institutions' opinions in relation to the topic. Omega-3 acids are essential fatty acids. A certain amount of omega-3 is needed in our daily diet; however, the usual consumption is generally less than the recommended amount. Changes in dietary patterns in the course of history have led to deficit levels of omega-3 in the human body. Currently, there is increasing evidence of the benefits of omega-3 in different medical specialities. There are still some gaps regarding its role in illnesses such as dementia, psychiatric disorders, and inflammatory diseases. Nevertheless, stronger evidence is being proved in cardiovascular diseases and cancer. This article provides a reflection on possible ways to increase omega-3 daily consumption and the constraints associated with food with high contents of heavy metals, which, in turn, are also rich in omega-3s.

BACKGROUND & AIM: n-3 fatty acid intake has been associated with inflammatory benefits in cardiovascular disease (CVD). Functionalising meat may be of great interest. The aim of the present study was to assess the effect of functional meat containing n-3 and rosemary extract on inflammatory and oxidative status markers in subjects with risk for CVD. METHODS AND RESULTS: A randomised, double-blind, cross-over study was undertaken to compare the effects on the above markers of consuming functional or control meat products. 43 volunteers with at least two lipid profile variables showing risk for CVD were randomly assigned to receive functional meat (FM) or control meat (CM) over 12-weeks with a 4-week wash-out interval before crossover. Functional effects were assessed by examining lipid profile, CRP, PAI-1, TNF-alpha, IL-6, fibrinogen (inflammatory markers), and TBARS, FRAP and 8-iso-PGF2 (oxidative status markers). 33 subjects (24 women) aged 50.7±8.8 years completed the study. In FM treatment, PAI-1, fibrinogen and 8-iso-PGF2 decreased significantly after 12 weeks, while FRAP significantly increased. In contrast, in CM treatment, a significant increase was seen in PAI-1, while FRAP significantly declined. Significant differences were also seen between the FM and CM treatments after 12 weeks in terms of the change observed in PAI-1, FRAP and 8-iso-PGF2 values. No significant differences were seen in anthropometric variables nor were adverse effects reported. CONCLUSION: The consumption of FM containing n-3 and rosemary extract improved oxidative and inflammatory status of people with at least two lipid profile variables showing risk for CVD. The inclusion of such functional meat in a balanced diet might be a healthy lifestyle option.
Objetivos: La ingesta de omega-3 se ha asociado con efectos antinflamatorios relacionados con la prevención de la enfermedad cardiovascular (ECV). Desarrollar productos cárnicos funcionales podría ser de gran interés para la población. El objetivo del presente estudio fue evaluar el efecto de una carne funcional con omega-3 y extracto de romero sobre marcadores de inflamación y oxidación en personas con riesgo cardiovascular. Pacientes y métodos: Se diseñó un ensayo clínico cruzado y doble-ciego para estudiar el efecto del consumo de un producto cárnico funcional sobre marcadores de inflamación y oxidación. Se incluyeron 43 voluntarios con al menos 2 parámetros del perfil lipídico alterado, indicando riesgo de ECV. Fueron asignados aleatoriamente en 2 grupos que consumieron en cruzado carne funcional (CF) o carne control (CC) durante 12 semanas con un periodo de lavado de 4 semanas entre ellos. Al finalizar el estudio se evaluó: perfil lipídico, marcadores de inflamación (PCR, PAI-1, TNF-alpha, IL-6, fibrinógeno) y marcadores de oxidación (TBARS, FRAP, 8-iso-PGF2ï¡). Resultados: Completaron el estudio 33 personas (24 mujeres) con edad media de 50.7±8.8 años. Tras consumir CF durante 12 semanas se observó una disminución significativa del PAI-1, fibrinógeno y 8-iso-PGF2ï¡, mientras que el FRAP incrementó significativamente. Sin embargo, con CC incrementó PAI-1 y disminuyó FRAP significativamente. Además se observaron diferencias significativas entre los cambios producidos tras consumir uno u otro producto de los marcadores PAI-1, FRAP y 8-iso-PGF2ï¡. Al final de cada intervención no se observaron cambios en variables antropométricas ni efectos adversos. Conclusiones: El consumo de CF con omega-3 y extracto de romero mejora el estado inflamatorio y oxidativo de personas con al menos 2 parámetros del perfil lipídico alterado. La inclusión de estas CF en una dieta equilibrada podría ser una opción más para mantener un estilo de vida saludable. ClinicalTrials.gov NCT0199088.

The role of diabetic nephropathy in the outcome of acute renal injury (AKI) is not well defined. Herein we evaluate the outcome of lipopolysaccharide- (LPS-) induced AKI in streptozotocin-induced diabetes, as well as the potential role of Hypoxia Inducible Factor (HIF-1 α ) in this condition. Although 6 h after LPS injection all mice developed a decrease in renal function, proteinuric diabetic mice showed a better recovery of this parameter throughout the study (72 h). Both HIF-1 α and vascular endothelium growth factor (VEGF) were found to be upregulated in diabetic mice. After LPS injection, all animals showed an upregulation of these factors, although it was higher in the diabetic group. Glycated albumin (GA) was found to upregulate HIF-1 α in HK-2 cells, which resulted in increased production of VEGF. Interestingly, LPS cooperated with GA to induce HIF-1 α upregulation. In conclusion, diabetic mice display a better recovery of AKI after experimental endotoxemia. Moreover, these animals showed an increased expression of both HIF-1 α and VEGF that was reproduced by incubating renal cells with GA. Since VEGF is considered a survival factor for tubular cells, our findings suggest that diabetes displays HIF-1 α upregulation that might function as a "precondition state" offering protection from endotoxic AKI.

INTRODUCTION: Oncohematologic patients usually present nutritional deficits associated with the disease, the treatments and side effects, etc. However, there are hardly any descriptive data about the dietary recommendations used and the patient's self-perception of its usefulness in their disease. AIM: To assess the self-perception of the nutritional importance in a group of oncohematologic patients. MATERIALS AND METHODS: 111 oncohematologic patients self-reported a questionnaire containing items about socio-sanitary data and self-perception of the nutritional importance in their disease. RESULTS: The mean age was 40.0 ± 12.8 years (64.86% women). The most frequent diagnosis and treatment was lymphoma (83.78%) and chemotheraphy (92.80%). 75% considered "very important" relationship between oncohematologic disease and nutritional status. Only 54.1% received dietary advice. And 53.2% and 50.5% considered that the use of nutritional supplements improve quality of life and/or disease respectively. CONCLUSIONS: A significant percentage of patients had advanced stages of their disease. However, half the group had not received dietary advice despite high interest in receiving nutritional care. Therefore, the nutritional assessment and the personalized nutritional support implementation of the patient should be included in routine clinical practice.
