Harmonisation de l'indication géographique dans la Loi de la propriété industrielle du Mexique

Les produits du terroir occupent une place privilégiée dans le goût des consommateurs qui, aujourd’hui, s’intéressent davantage à connaître la provenance et les qualités des produits qu’ils consomment. Le Mexique a une grande variété de produits du terroir, appris et transmis aux producteurs de génération en génération, mais certains manquent de protection ou la protection est inefficace. Les producteurs du Mexique vivent souvent dans des conditions marginales, et l'imitation de leurs produits résulte en une réduction de leurs ventes. Ils sont souvent contraints à changer de métier. Cette situation met en péril le patrimoine national en raison de l’abandon des connaissances traditionnelles, lesquelles représentent l'identité et la diversité culturelle de la nation mexicaine. La « Ley de la Propiedad Industrial » (LPI) prévoit l'appellation d’origine et la marque collective en tant que mécanismes de protection; cependant, ils ne sont pas toujours adéquats pour assurer une protection efficace des produits du terroir. Notre objectif est d'analyser si l'inclusion de l’indication géographique à la LPI peut favoriser l’enregistrement des produits du terroir qui sont à risque de disparaître. Cette étude fait donc ressortir la nécessité de modifier la LPI afin qu’elle réponde mieux aux besoins et aux réalités du Mexique.

Facteurs de risque de calcifications vasculaires en insuffisance rénale constituant une contre-indication à la greffe rénale

On estime que des calcifications vasculaires (CVs) sont présentes chez 60% des patients avec insuffisance rénale terminale (IRT) et que ces CVs contribuent à l’augmentation de la maladie cardiovasculaire chez ces patients. La maladie cardiovasculaire est la première cause de mortalité chez les patients en IRT. La transplantation rénale est le traitement de choix en IRT mais peut être contre-indiquée pour des raisons chirurgicales liées au CVs ou en raison d’un risque de complications cardiovasculaires postopératoires trop élevé associé à la présence de CVs sévères. Il est donc primordial de déterminer quels facteurs sont associés à la présence de CVs qui rendraient le patient non-éligible pour une greffe rénale. En particulier il serait intéressant de vérifier si un produit phosphocalcique élevé est un facteur de risque de non-éligibilité pour une greffe rénale en raison de CVs. L’étude actuelle utilise la base de données de transplantation du CHUM. C’est une étude de type cas-témoins avec une cohorte de 1472 patients de 1992 à 2009. Les cas sont les patients jugés non-éligibles pour une transplantation rénale en raison de la présence de CVs sévères. Les contrôles sont les patients jugés éligibles: 80 cas et 80 contrôles ont été inclus. Les facteurs de risque qui ont été identifiés pour la non-éligibilité en raison de CVs sont le diabète (adjusted Odds Ratio (OR): 5.55 (1.98 - 15.59)), l’âge (OR: 1.14 (1.09 – 1.2)), le tabagisme (OR: 9.51 (2.55 – 35.51)) et la dialyse (OR: 6.83 (2.33 – 20.05)). La durée de la dialyse a aussi été identifiée comme facteur de risque (OR : 8.61 (2.34-31.68) pour une durée de dialyse de 8 mois et plus, OR : 4.57 (1.42-14.65) pour une durée de dialyse de 1 à 7 mois. Bien que significatif en univarié, le produit phosphocalcique n’a pas été identifié comme facteur de risque significatif dans les analyses multivariées. En conclusion, cette étude montre que le produit phosphocalcique pourrait être un marqueur d’une insuffisance rénale prolongée et moins bien contrôlée plutôt qu’un facteur de risque de calcifications rendant le patient non-éligible à la greffe. De plus cette étude met de l’emphase sur la notion qu’il est primordial 1) de référer précocement les patients à haut risque de CVs vers un centre de transplantation pour une évaluation et 2) de prendre en charge agressivement l’arrêt du tabac chez tous les patients qui sont potentiellement éligibles pour une transplantation.

Soil geochemical analyses as an indication of metal working at the excavation of a house in the Roman City at Silchester (UK)

Silchester is the site of a major late Iron Age and Roman town (Calleva Atrebatum), situated in northern Hampshire (England (UK)) and occupied between the late first century BC and the fifth or sixth century AD. Extensive evidence of the nature of the buildings and the plan of the town was obtained from excavations undertaken between 1890 and 1909. The purpose of this study was to use soil geochemical analyses to reinforce the archaeological evidence particularly with reference to potential metal working at the site. Soil analysis has been used previously to distinguish different functions or land use activity over a site and to aid identification and interpretation of settlement features (Entwistle et al., 2000). Samples were taken from two areas of the excavation on a 1-metre grid. Firstly from an area of some 500 square metres from contexts of late first/early second century AD date throughout the entirety of a large 'town house' (House 1) from which there was prima facie evidence of metalworking.

Zr- AND Ba-RICH MINERALS FROM THE PONTE NOVA ALKALINE MAFIC-ULTRAMAFIC MASSIF, SOUTHEASTERN BRAZIL: INDICATION OF AN ENRICHED MANTLE SOURCE

Zirconium- and Ba-rich minerals are found in gabbroic rocks from the Ponte Nova alkaline mafic-ultramafic massif in southeastern Brazil. The unusual mineralogical assemblage includes zirconolite, baddeleyite, Ba-rich alkali feldspar, and Ba- and Ti-rich biotite. Zirconolite of the Ponte Nova massif has higher levels of Zr (up to 1.172 apfu) than those registered in other terrestrial rocks and a prominent enrichment in the light rare-earth elements. Baddeleyite contains small quantities of Hf, Ti, and Fe. The Ba-rich alkali feldspar and Ba- and Ti-rich biotite contain up to 9.25 and 7.35 wt% BaO, respectively, and the biotite contains up to 12.01 wt% TiO(2). In the different intrusions of the Ponte Nova massif, such an unusual assemblage typifies the residual magma after the crystallization of clinopyroxene and olivine from previously enriched basanitic parental magma. The different trends of enrichments in REE and Th + U found for zirconolite of the intrusions of the Ponte Nova massif provide a better understanding of the variable degrees of enrichment of incompatible elements of the distinct gabbroic bodies. A lithospheric mantle source enriched in incompatible elements by the metasomatic action of volatile-rich fluids and with the presence of phlogopite or amphibole (or both) and other minor accessory phases could explain the presence of the Zr- and Ba-rich minerals in this gabbroic massif.

Tomographic index as auxiliary criteria for surgery indication in fracture dislocation of acetabulum posterior wall

There are situations which the tomographic exam is done on the affected hip or situations where the contralateral hip presents abnormalities that make it impossible to compare. In this study we aimed to evaluate a tomographic index that does not require comparison between the both hips. Twenty two patients with unilateral acetabular fracture dislocation with fracture of posterior wall were studied. We established the relationship between the remaining posterior wall and the femoral head diameter (head/wall index-H/W index). We evaluated 45 two-dimensional computed tomography scan in normal hips and established the H/W index. In 45 normal hips we simulated a posterior wall fracture with involvement of 25% and 30% of the posterior wall and calculated the H/W index. We divided into five groups with five different H/W index (fractured group with non surgical treatment; fractured group; normal group; normal group with simulated fracture of 25% and; 30% of the posterior wall). 2.4 was the lowest limit of confidence interval of the group with 25% of the posterior wall fracture. When we analyzed the confidence interval of the 30% fracture group the upper limit of the confidence interval was 2.7, close to the lower limit of the surgical group that was 2.9. Thus, we suggest the 2.4 the H/W index limit as an auxiliary criteria to indicate whether or not to operate. H/W index is helpful to decide whether or not surgery indication in the fracture dislocation of the posterior wall of the acetabulum. © 2012 Fujiki et al.; licensee BioMed Central Ltd.

Is price dispersion always an indication of price discrimination?

It has been established for a long time that there is significant dispersion in prices charged for seemingly homogeneous goods. This may happen in competitive markets because the world is not frictionless, and certainly in other markets where price discrimination is carried out by firms with oligopolistic power. This paper is the first survey of the economic literature on price dispersion that addresses the following three key issues: i) its characteristics as a result of optimizing search behavior; ii) its relevance as a reflection of price discrimination and its consequences for social welfare and policy intervention; and iii) the empirical evidence of price dispersion. By contributing to a better understanding of price dispersion, this survey may help in the design and implementation of competition and anti-trust policies

Patients from the Oral Oncology Center, UNESP, Araçatuba with an indication for prosthesis

Head and neck tumors are a major health concern worldwide, due to their high incidence and mortality rates, particularly in developing countries. In Brazil, this type of cancer is commonly diagnosed and studies suggested that it may be the leading cause of mortality in the country. The increase in life expectancy worldwide, as well as environmental and behavioral factors, are related to carcinogenesis. Therefore, an understanding of basic epidemiology and statistical methods is critical, in order to promote early diagnosis and cancer prevention. Cancer patients with an indication for prosthesis were selected from the medical records of the Oral Oncology Center, School of Dentistry, São Paulo State University (UNESP), Araçatuba, between 1991 and 2010. The following variables were recorded: gender, age, type and location of the lesion, radiation dose and dental prosthesis. The majority of the patients were male (74.15%) and >60 years of age (53.37%). Tumors were most commonly located in the floor of the mouth (11.1%) and squamous cell carcinoma was the most prevalent type (72.8%). This study provides the profiles of patients who attended the Oral Oncology Center and the results may aid in the creation of cancer prevention programs.

Conjunctival inflammation in patients under topical glaucoma treatment with indication to surgery

PURPOSE: To compare the frequency of conjunctival HLA-DR expression (a surrogate marker for inflammation) in eyes treated with topical prostaglandin analogues versus eyes treated with other topical antiglaucomatous drugs. METHODS: Patients diagnosed with primary open-angle glaucoma presenting indication for trabeculectomy were divided in groups according to the use or not of prostaglandin analogues. All subjects were treated with the maximum tolerated dose of antiglaucomatous drugs until the date of the surgery. At the beginning of the surgical procedure, a 5 x 5 mm biopsy of the bulbar conjunctiva was collected, incubated with monoclonal anti-HLA-DR antibody and processed for histological analysis. RESULTS: Of the 31 eyes included (31 patients), 25 were under topical prostaglandin analogues (Group 1) and six under other topical pharmacological agents (Group 2). Fourteen eyes of Group 1 (56%) and three of Group 2 (50 %) were positive for the inflammatory marker HLA-DR (P=1.0). The percentage of stained cells ranged from 15.49 to 48.09% (median: 27.61) in Group 1, and from 18.35 to 28 (median: 20.71) in Group 2, with no differences statistically significant (p=0.33). CONCLUSION: The use of prostaglandin analogues did not increase conjunctival expression of HLA-DR compared to other topical antiglaucomatous agents.

Biomarker responses as indication of contaminant effects in Oreochromis niloticus

The current study investigated oxidative stress parameters (enzymes activities, metallothionein content and lipid peroxidation) in freshwater fish, Oreochromis niloticus, tilapia exposure to Monjolinho River (in 4 months of year: January, April, July and November). One critical site in Monjolinho River (site B) was assessed in comparison to a reference site (site A). Water pH and oxygen concentration was lower than that recommended by CONAMA (Brazilian National Environmental Committee), resolution 357/2005 for protection of aquatic communities, and ammonium and the metals Cu, Zn, Mn and Fe (on all months) concentrations were higher than the maximum concentration recommended. Glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were significantly decreased in liver and muscle in tila. pia from Monjolinho River, throughout the year, in relation to reference except in gills that SOD activity increased. Glutathione S-transferase (GST) activity was significantly increased in liver of the tilapia from Monjolinho River in all sites, in relation to reference except in gills that GST activity increased in July and decreased in November, suggesting that GST activity could be induced to neutralize the pollutants toxicity. On the other hand, GST activity was significantly decreased in white muscle indicating a toxic effect of pollutants, resulting in a decreased ability of tilapia to perform defense reactions associated to GSTs. The decrease of catalase (CAT) activity in gills of the O. niloticus together with the increase of SOD activity, could explain the increased lipid peroxidation (LPO) level in this organ. Metallothionein levels in liver and gills were significantly high in all sites. Results indicate that the exposure to metals caused severe damage to tissues; despite the consensually assumed antioxidant induction as a sign of exposure to contaminants the effects seem in part to be mediated by suppression of antioxidant system with SOD, CAT and GPx as potential candidates for tissues toxicity biomarkers of pollutants.

Hepatocellular adenoma: an excellent indication for laparoscopic liver resection

Objectives: Laparoscopic resection for benign liver disease has gained wide acceptance in recent years and hepatocellular adenoma (HA) seems to be an appropriate indication. This study aimed to discuss diagnosis and treatment strategies, and to assess the feasibility, safety and outcomes of pure laparoscopic liver resection (LLR) in a large series of patients with HA. Methods: Of 88 patients who underwent pure LLR, 31 were identified as having HA. Diagnosis was based on radiological evaluation and resections were performed for lesions measuring >5.0 cm. Results: The sample included 29 female and two male patients. Their mean age was 33.2 years. A total of 27 patients had a single lesion, one patient had two and one had four lesions. The two remaining patients had liver adenomatosis. Mean tumour size was 7.5 cm. Three right hepatectomies, 17 left lateral sectionectomies and 11 wedge resections or segmentectomies were performed. There was no need for blood transfusion or conversion to open surgery. Postoperative complications occurred in two patients. Mean hospital stay was 3.8 days. Conclusions: Hepatocellular adenoma should be regarded as an excellent indication for pure LLR. Pure LLR is safe and feasible and should be considered the standard of care for the treatment of HA when performed by surgeons with experience in liver and laparoscopic surgery.

Clinical and surgical evaluation of the indication of postoperative antibiotic prescription in third molar surgery

Objective. The aim of this study was to evaluate the need for antibiotic prescription in third molar surgery. Study design. A double-blind randomized study was carried out with 71 patients from CODONT (Dentistry Center of the Police of Sao Paulo). Amoxicillin, clindamycin, or no medication was administered for 7 days immediately after surgery. The participants evaluated the presence of pain, edema, interincisal distance (ID), presence of infection, Pell and Gregory classification, rescue analgesia, osteotomy, and odontosection. Results. There was no difference (P < .05) between antibiotics and control over the surgery duration, dose, visual analog scale (VAS), ID, and edema, yet significant differences were seen over time for VAS, edema, and ID. Conclusions. Antibiotic prescription should not be indicated in all clinical conditions, yet it is necessary to correctly evaluate factors such as systemic condition of the patient, skill of the operator, and contamination of the surgical environment.
