Abstract
Introducción y objetivos: Ugni molinae (Myrtaceae) es una especie arbustiva nativa del sur de Chile − donde se la conoce como “murta” o “murtilla” − y de Argentina. Este estudio tiene como objetivo aportar información morfo-arquitectural de U. molinae, y así promover su cultivo e introducción en sistemas productivos de Argentina.
M&M: Se realizaron observaciones de U. molinae a diferentes niveles (planta completa, ejes y brotes anuales) sobre plantas desarrolladas en poblaciones naturales y plantas derivadas de semillas o de enraizamiento de estacas y mantenidas en viveros por cinco años.
Resultados: Los brotes cortos de U. molinae completan su extensión sin ramificarse, mientras que los brotes de mayor longitud pueden ramificarse durante su alargamiento a partir de nudos intermedios y/o distales. El inicio de la floración se produce a partir del segundo al tercer año desde la germinación de una semilla o del enraizamiento de una estaca. La mayoría de las flores se forman a fines de la primavera a partir de nudos basales de brotes en alargamiento. La arquitectura de las plantas cambia desde claramente jerárquica a no-jerárquica en los primeros años de desarrollo.
Conclusiones: Ugni molinae puede multiplicarse con facilidad a partir del enraizamiento de estacas o de germinación de semillas. El desarrollo de un entrenudo corto asociado a hojas verdes pequeñas es un claro indicador del límite entre brotes anuales sucesivos. Se necesitan estudios más detallados acerca del desarrollo y la productividad de esta especie en la Argentina para evaluar su inclusión en sistemas productivos.

Abstract
This study has evaluated the effect of EVOO (Extra-Virgin olive oil), OA (oleic acid) and HT (hydroxytyrosol) in an induced model of MS through experimental autoimmune encephalomyelitis (EAE).Dark Agouti 2-month old rats (25 males) were divided into five groups: (i) control group, (ii) EAE group, (iii) EAE+EVOO, (iv) EAE+HT, and (v) EAE+OA. At 65 days, the animals were sacrificed and the glutathione redox system and bacterial lipopolysaccharide (LPS) and LPS-binding protein (LBP) products of the microbiota in brain, spinal cord, and blood were evaluated.Gastric administration of EVOO, OA, and HT reduced the degree of lipid and protein oxidation, and increased glutathione peroxidase, making it a diet-based mechanism for enhancing protection against oxidative damage. In addition, it reduced the levels of LPS and LBP, which appeared as being increased in the EAE correlated with the oxidative stress produced by the disease.

Abstract
OBJECTIVE To determine whether maternal diet supplementation with omega-3 long chain polyunsaturated fatty acids (omega-3 LC-PUFAs) during the last trimester of pregnancy and the breastfeeding period influences the levels of inflammatory cytokines in mother and infants. MATERIAL AND METHOD This registered, double-blind randomized study included 46 pregnant women, who were randomly allocated to either an experimental group receiving 400mL/day of a fish oil-enriched dairy drink [320mg docosahexaenoic acid (DHA) + 72mg eicoapentaenoic acid] (FO group, n = 24) or to a control group receiving 400mL/day of a non-supplemented dairy drink (CT group, n = 22), from week 28 of pregnancy until the fourth month of lactation. During the study, maternal dietary patterns were monitored by a nutritionist, who encouraged compliance with current recommendations of fatty acids intake. DHA concentrations and cytokine levels (GM-CSF, IL-2, IL-4, IL-6, IL-10, INF-γ and TNF-α) were measured in maternal plasma at the moment of recruitment and in maternal (n = 46) and infant (n = 46) plasma at birth and 2.5 months after birth. RESULTS Maternal plasmatic IL-4 levels were higher in FO than in CT subjects (p = 0.009). Additionally, a tendency was observed to higher IL-10 and IL-2 in the FO group. Plasmatic IL-6 however, was higher in CT mothers (p = 0.001). TNF-α was higher in CT infants at birth and 2.5 months after birth (p = 0.005). An analysis of possible relationships between DHA and the concentrations of different cytokines revealed negative correlation between maternal plasmatic IL-6 and DHA (higher plasmatic DHA corresponded to lower IL-6). CONCLUSIONS Maternal dietary omega-3 LC-PUFAs supplementation during critical periods like pregnancy, lactation and early newborn development may influence the levels of certain inflammatory cytokines, reducing pro-inflammatory cytokines and promoting an anti-inflammatory "environment".

Abstract
BACKGROUND AND PURPOSE The use of cerebral protection during CAS is an extended practice. Paradoxically it is open to question because it can lead to potential embolic complications. The aim of this study was to evaluate the safety and efficacy of CASWPD in patients with severe symptomatic carotid artery stenosis. MATERIALS AND METHODS A prospective study was performed including 210 consecutive patients (201 symptomatic and 9 asymptomatic) with carotid artery stenosis >70%. All patients were treated by CASWPD. Angiographic results and neurologic complications were recorded during the procedure and within 30 days after it. All patients underwent clinical evaluation and Doppler sonography follow-up at 3, 6, and 12 months after the procedure. RESULTS Two hundred twenty carotid arteries were treated. The average degree of stenosis was 88.9%. The procedure was successfully completed in 212 (96.4%) arteries. After stent placement, 98.6% of arteries showed no residual stenosis or <30%. Balloon angioplasty dilation before stent placement was performed in 16% of cases. During the 30-day periprocedural period, there were 3 major complications (1.4%), including 1 disabling ischemic stroke, 1 acute stent thrombosis, and 1 MI. The last 2 patients died from these complications. At 1-year follow-up 24 (12.8%) restenoses, 2 new ipsilateral strokes, 1 contralateral stroke, and 5 deaths (2.7%) had occurred. None of these deaths were related to the initial stroke. CONCLUSIONS In our study, unprotected stent placement in symptomatic patients with severe carotid artery stenosis has demonstrated a low incidence of complications. We believe that this is due to the reduction of maneuvering and manipulation through the stenosis and to the protective effect of the stent placement before angioplasty balloon dilation.

Abstract
This review summarizes studies on the role of olive oil intake in the prevention and attenuation of mitochondrial oxidative stress derived from several situations such as ageing, physical exercise, treatment with adriamycin or intake of thermally oxidised oils. After more than fifteen years of studies on these issues, results have demonstrated that under different models of oxidative stress the regular intake of virgin olive oil as dietary fat is able to attenuate or increase free radical production at the mitochondrial level to a lower extent than when n-6 polyunsaturated oils are used. In the same way, virgin olive oil leads to better function of the mitochondrial electron transport chain.

Abstract
Physical exercise and fatty acids have been studied in relation to mitochondrial composition and function in rat liver, heart, and skeletal muscle. Male rats were divided into two groups according to dietary fat type (virgin olive and sunflower oils). One-half of the animals from each group were subjected to a submaximal exercise for 8 weeks; the other half acted as sedentary controls. Coenzyme Q, cytochromes b, c + c1, a + a3 concentrations, and the activity of cytochrome c oxidase were determined. Regular exercise increased (P < 0.05) the concentration of the above-mentioned elements and the activity of the cytochrome c oxidase by roughly 50% in liver and skeletal muscle. In contrast, physical exercise decreased (P < 0.05) cytochrome c oxidase activity in the heart (in micromol/min/g, from 8.4+/-0.1 to 4.9+/-0.1 in virgin olive oil group and from 9.7+/-0.1 to 6.7+/-0.2 in sunflower oil animals). Dietary fat type raised the levels of coenzyme Q, cytochromes, and cytochrome c oxidase activity in skeletal muscle (P < 0.05) among the rats fed sunflower oil. In conclusion, dietary fat type, regular exercise, and the specific tissue modulate composition and function of rat mitochondria.

Abstract
The effects of four edible oils on lipid peroxidation have been investigated in rabbit heart mitochondrial membranes. The experimental oils (olive oil from the variety "picual", washed olive oil from the variety "picual", olive oil from the variety "arbequina" and high-oleic sunflower oil) had a similar fatty-acid composition, but differed in their unsaponified fraction (polyphenols, tocopherols, and others). The lowest hydroperoxide levels were found with picual and washed picual. No differences in mitochondrial membrane thiobarbituric acid reactive substance (TBARS), alpha-tocopherol concentrations and cytosolic antioxidant enzymes (superoxide dismutase, glutathione peroxidase, glutathione reductase and catalase) were found, whereas the CoQ10 content correlated inversely with hydroperoxide levels in all groups. These results suggest that mitochondrial membranes with high levels of monounsaturated fatty acids generate low levels of lipid peroxidation. Moreover, the saponified fraction of the experimental diets proved more important in preventing lipid peroxidation than the unsaponified fraction. Lastly, coenzyme Q may help to prevent peroxidative stress damage in rabbit heart mitochondria.

Abstract
Physical exercise induces oxidative stress. Dietary fat modulates lipid composition of plasma and fatty acid profile of mitochondrial membranes. Over 8 wk, two groups of rats were fed virgin olive oil or sunflower oil as the only fat sources. Both groups were divided into 4 subgroups according to exercise: one of sedentary rats and the other three of rats subjected to different exercises on a treadmill. There was a lower concentration of vitamin A and coenzyme Q in the plasma of animals subjected to exercise compared to the sedentary animals. The concentrations of these molecules in liver and skeletal muscle mitochondria of animals exercised until exhaustion were higher than in sedentary animals. This can suggest the existence of a balance between plasma and mitochondrial membrane for these antioxidants as a response to an oxidative attack.

Abstract
The mitochondrial theory of aging suggests that this phenomenon is the consequence of random somatic mutations in mitochondrial DNA, induced by long-term exposure to free radical attack. There are two potential dietary means of delaying the effects of free radicals on cellular aging, i.e., enrichment of mitochondrial membranes with monounsaturated fatty acids and supplementation with antioxidants. We have performed a preliminary study on male rats, 6 or 12 month old, fed with diets differing in the nature of the fat (virgin olive oil or sunflower oil) and/or with antioxidant supplementation (coenzyme Q10), analysing hydroperoxide and coenzyme Q9 and Q10 in heart mitochondria. Preliminary results allow us to conclude that the CoQ10 dietetic supplementation as well as the enrichment of the cellular membranes with monounsaturated fatty acids, successfully protect mitochondrial membranes from aged rats against the free radical insult.

Abstract
The most probable factor connecting premature infant problems such as retinopathy, intraventricular hemorrhage and chronic lung disease appears to be the excessive production of oxygen free radicals which can occur as a consequence of oxygen therapy. The aim of our investigation was to elucidate the possible correlations between lipid peroxidation, in this study measured as hydroperoxides production, and antioxidant concentrations in erythrocyte membranes of both full term and preterm infants. Hydroperoxide concentrations were found to be high, especially in premature infants, in erythrocyte membranes at birth and in the initial days of life. The erythrocyte membranes were also found to contain low levels and/or low activities of antioxidant defense mechanisms which was more evident in premature newborns where alpha-tochopherol levels were significantly lower in comparison to full term infant levels. Furthermore, when premature infants undergo oxygen therapy these effects were exacerbated. These results demonstrate that at birth, particularly in the premature newborn, the degree of oxidative stress outweighs the antioxidant defense mechanisms.

Abstract
Plasma is an important vehicle through which antioxidant molecules are conveyed and in which they may show different behaviors, either acting as a protective factor for oxidative damage to different blood elements or using it as a vehicle through which dietary antioxidant factors would be distributed to the body. The aim of the study was to determine the plasma level of vitamin E, coenzyme Q, uric acid and vitamin A and their relation with the cellular oxidative damage mediated by physical training and the ingestion of different fat (virgin olive and sunflower oils). Male Wistar rats were divided into 8 subgroups based on the dietary fat intake and their physical activity. Results show that both dietary fat and physical training affect susceptibility to iron-induced lipid peroxidation in plasma and the tissues that were studied. The increase of this lipid peroxidation parallels a decrease of the level of all the plasma antioxidants that were studied.

Abstract
Two patients, aged 59 and 73 years, presented with the clinical syndrome of Posterior Cortical Dementia (PCD). Follow-up during 3 and 11 years confirmed the progressive nature of the disorder. Posterior cerebral impairment was seen on SPECT studies. Neuroimaging studies showed an early dilatation of the right occipital ventricular horn which predominated over the cortical atrophy. This kind of cerebral atrophy could identify a subset of PCD cases that may be unrelated to Alzheimer's disease.

Abstract
Cluster tic syndrome (CTS) is a disorder characterized by three types of pain attacks. One resembles trigeminal neuralgia, the second resembles cluster headache, and the third is mixed, starting as a neuralgic pain immediately followed by a homolateral headache accompanied by autonomic signs. This type of attack is pathognomonic for CTS. The three pain types can all be provoked. CTS appears between ages 20 and 70 and may be either episodic or chronic; medical treatment is poor.

Abstract
A Spanish family with the DTI variant sensitive to L-Dopa is presented with three patients, 2 first cousins and an aunt being described. The dystonic beginning of the disease during infancy is of note in the former two patients as is the later initiation of parkinsonism in the third patient. Marked improvement was observed in all of the patients with L-Dopa treatment. Some peculiarities of the cases are commented upon and the discussion includes analysis of the nosological aspects, relation with juvenile parkinsonism and Parkinson's disease. Finally, reference is made to the different hypersensitivity for presenting choreic dyskinesia which the patients had.
