The most common types of orofacial pain originate at the dental or periodontal level or in the musculoskeletal structures. However, the patient may present pain in this region even though the source is located elsewhere in the body. One possible source of heterotopic pain is of cardiac origin. Objectives: Report two cases of orofacial pain of cardiac origin and review the clinical cases described in the literature. Study Design: Description of clinical cases and review of clinical cases. Results and conclusions: Nine cases of atypical pain of cardiac origin are recorded, which include 5 females and 4 males. In craniofacial structures, pain of cardiac origin is usually bilateral. At the craniofacial level, the most frequent location described is in the throat and jaw. Pain of cardiac origin is considered atypical due to its location, although roughly 10% of the cases of cardiac ischemia manifest primarily in craniofacial structures. Finally, the differential diagnosis of pain of odontogenic origin must be taken into account with pain of non-odontogenic origin (muscle, psychogenic, neuronal, cardiac, sinus and neurovascular pain) in order to avoid diagnostic errors in the dental practice as well as unnecessary treatments.

Objective: We propose and validate a computer aided system to measure three different mandibular indexes: cortical width, panoramic mandibular index and, mandibular alveolar bone resorption index. Study Design: Repeatability and reproducibility of the measurements are analyzed and compared to the manual estimation of the same indexes. Results: The proposed computerized system exhibits superior repeatability and reproducibility rates compared to standard manual methods. Moreover, the time required to perform the measurements using the proposed method is negligible compared to perform the measurements manually. Conclusions: We have proposed a very user friendly computerized method to measure three different morphometric mandibular indexes. From the results we can conclude that the system provides a practical manner to perform these measurements. It does not require an expert examiner and does not take more than 16 seconds per analysis. Thus, it may be suitable to diagnose osteoporosis using dental panoramic radiographs

The organization, assembly and remodeling of the actin cytoskeleton provide force and tracks for a variety of (endo)membrane-associated events such as membrane trafficking. This review illustrates in different cellular models how actin and many of its numerous binding and regulatory proteins (actin and co-workers) participate in the structural organization of the Golgi apparatus and in traf- ficking-associated processes such as sorting, biogenesis and motion of Golgi-derived transport carriers.

How did farmers maintain soil fertility as they cultivated the same land over decades and centuries? How did they transfer energy and nutrients (nitrogen, potassium, phosphorous) across the landscape to fertilize crops? How did farmers structure landscapes (field, pasture, woodland) to sustain communities, ensure long-term productivity, and produce profits? We summarize in this article the results of the ongoing research on the last stage of organic agriculture in Catalonia carried out by our project. We also outline the forthcoming steps to continue our research.

Objetivo: Las enfermedades graves como el cáncer pueden vivirse como experiencias traumáticas y/o como impulso para realizar cambios vitales positivos (ej. crecimiento postraumático). El programa de psicoterapia positiva grupal para supervivientes de cáncer que realizamos integra ambos elementos, trauma y crecimiento. Los objetivos del programa no son sólo la reducción de emociones negativas (malestar emocional o sintomatología postraumática) sino el trabajo con emociones positivas y la facilitación de crecimiento postraumático. Método: Los elementos de trabajo psicoterapéutico que han mostrado evidencia en la consecución de estos objetivos y que componen los módulos de este programa son: favorecer la expresión y procesamiento emocional, entrenar habilidades de regulación emocional y estrategias de afrontamiento, trabajo con elementos facilitadores del crecimiento postraumático y confrontación con los aspectos existenciales y espirituales que surgen tras el diagnóstico y tratamiento oncológico. Además de estos aspectos psicoterapéuticos, complementamos el programa con otros factores relevantes en la adaptación psicosocial tras la enfermedad como: el fomento de estilos de vida saludables, la adherencia a los tratamientos oncológicos, la reinserción laboral y los comportamientos solidarios. Resultados: Los resultados preliminares del programa muestran mayor reducción de sintomatología postraumática y mayor crecimiento postraumático en el programa de psicoterapia positiva en el seguimiento a 3 meses al compararlo con un programa anterior centrado únicamente en la reducción de malestar emocional.

No existen protocolos claramente establecidos para el tratamiento de la boca seca. El objetivo de este trabajo es realizar una revisión sistemática de la literatura médica de los últimos 10 años. Hemos utilizado las palabras: «dry mouth», «prognosis», «treatment» y «dentistry». En una primera búsqueda hemos encontrado 1.450 entradas. Con la restricción «clinical trials OR randomized controlled trial OR systemic reviews» se han reducido a 522, de las que 145 eran metaanálisis y revisiones sistemáticas. Se han eliminado las que no eran pertinentes al tema y han quedado reducidas a 53. Posteriormente se descartaron 24 (8 no pertinentes, 7 revisiones y 9 opiniones personales). De los 29 artículos analizados, 15 son ensayos clínicos controlados, 2 ensayos no controlados, 4 estudios observacionales, 2 revisiones sistemáticas y 5 revisiones. Los enfermos mejor estudiados son los pacientes con síndrome de Sjögren y los pacientes irradiados. El tratamiento se centra en el etiológico, preventivo, sintomático, de estimulación salival local y sistémicos. Podemos concluir que el tratamiento debe ser individualizado, pudiéndose aplicar sustitutos salivales y diferentes técnicas de estimulación mecánica. There are no clearly established protocols for the treatment of dry mouth. The aim of this paper is a systematic review of the literature of the past 10 years using the words «dry mouth», «prognosis», «treatment» and «dentistry». The initial search found 1,450 entries and within the restriction «clinical trials OR randomized controlled trial OR systemic reviews» it has been reduced to 522, which 145 were meta-analysis and systematic reviews. Papers not relevant to the issue were removed reducing the entries to 53. Twenty-four were dismissed (8 irrelevant, 7 reviews without adequate information and 9 personal opinions). Of the 29 items tested, 15 were controlled trials, 2 uncontrolled trials, 4 observational studies, 2 systematic reviews and 5 non systematic reviews. The most studied patients were Sjögren's syndrome and the irradiated patients. Treatments are focused on the etiology, prevention, symptomatic, local salivary stimulation and systemic treatments. It can be concluded that treatment must be individualized, salivary substitutes and mechanical stimulation techniques can be applied.

Mai com ara els informes internacionals sobre els sistemes educatius havien tingut tanta repercussió mediàtica i havien estat tant de moda. Diversos són els factors que explicarien aquest fenomen, com ara l"exigència de la societat de passar comptes amb el sistema escolar o la gens menyspreable tendència a la uniformització dels sistemes nacionals, tot arraconant el"desinteressat interès" aventurer per conèixer altres mons, que caracteritzava els primers estudis internacionals en pedagogia. Les anàlisis i valoracions que se"ns mostren en el llibre que recomanem i que suscita aquestes reflexions, coordinat pels professors Joaquim Prats i Francesc Raventós1, de la Universitat de Barcelona, entronquen amb una tradició que ens ve de lluny per conèixer què s"hi fa en altres llocs: la pedagogia comparada té llarga prèdica entre nosaltres.

El paisatge agrari -entès en termes físics- és una construcció humana fruit d'una activitat productiva -la practica de l'agricultura- a traves de la qual s'imprimeix conscientment una determinada forma als espais naturals tot cercant l'adaptació dels objectius productius a les variades condicions del medi. Els elements que componen un paisatge agrari són múltiples i abasten des del tipus de poblament fins a la forma de les parcel•les, passant pel sistema hidrogràfic, el mode d'apropiació dels espais, les característiques de l'explotació ramadera i les formes d'aprofitament del sòl. En aquest article ens ocuparem d'un dels components del paisatge agrari de la comarca del Baix Empordà, concretament dels usos del d l i de les principals línies productives que caracteritzaven l'agricultura baixempordanesa a mitjan segle XIX. La primera qüestió que tractarem serà la de la paralització del procés d'expansió de l'àrea conreada just després de les dècades centrals del segle, aspecte de gran interès tant per la seva precocitat en el context català i espanyol, com pel fet que revela un canvi en l'evolució del sector estretament relacionat amb una remarcable disminució de la pressió demogràfica. En segon lloc, a partir de la contrastació de fonts documentals de naturalesa diversa (amillaraments, estadístiques provincials, interrogatoris municipals i comptabilitats privades), realitzarem un intent de quantificar el pes dels diversos aprofitaments i la seva distribució geogràfica. I, finalment, plantejarem la qüestió de la intensificació de l'ús del sòl a través del retrocés del guaret blanc i la difusió de rotacions complexes, qüestió clau en l'avaluació de l'eficiència econòmica del sistema agrari baixempordanès

En aquest article intentem resseguir, en primer lloc, la percepció que les classes propietàries de la terra van tenir del canvi que implicava el desenvolupament d'una agricultura capitalista, les maneres com ho van intentar racionalitzar i els projectes que van anar formulant i impulsant entre mitjan segle XIX i la Primera Guerra Mundial a mesura que avançava simultàniament la integració de l'activitat agrària en el mercat i es consolidaven els processos d'industrialització i urbanització. Tanmateix, la nostra anàlisi no es mantindrà en el pla ideològic i doctrinal, sinó que la part més substantiva la dedicarem a examinar les diverses i successives xarxes de relacions socials entre els propietaris de la terra i la força de treball predominants en l'agricultura catalana i la seva relació amb els principals canvis econòmics que paral·lelament s'anaren materialitzant

Objective: To determine the clinical characteristics of the orofacial pain of cardiac origin in patients visited when doing a treadmill exercise test, at the cardiology service of the Can Ruti Hospital in Badalona (Barcelona, Spain). Study design: The sample of that study included thirty patients visiteding when doing a treadmill exercise test, at the cardiology service. The questionnaire has been asked to a sample of 30 patients. Results: Eleven of the 30 patients included in this study presented craniofacial pain before or during the cardiac seizure. The location of the pain was bilateral, non-irradiated at the mandible in all cases. The intensity of the pain was from slight to severe. The frequency of the appearance of the pain was paroxysmal in 8 cases and constant in three cases, and the duration was from a few hours to a maximum of 14 days. Discussion: The cardiac pain in craniofacial structures is usually bilateral, compared to odontogenic pain which is always unilateral. The pain of cardiac origin is considered atypical because of its location, but about the 10 % of the cases, the cardiac ischemia has its primary manifestation in orofacial structures. Conclusions: Eleven patients referred a bilateral non-irradiated mandibular pain, with intensity from slight to severe, and with a paroxystic frequency in eight cases and a constant frequency in three cases. Just one patient referred pain during the treadmill exercise test. In all cases the pain disappeared after the cardiac surgery or the administration of vasodilators.

Striatal adenosine A2A receptors (A2ARs) are highly expressed in medium spiny neurons (MSNs) of the indirect efferent pathway, where they heteromerize with dopamine D2 receptors (D2Rs). A2ARs are also localized presynaptically in cortico-striatal glutamatergic terminals contacting MSNs of the direct efferent pathway, where they heteromerize with adenosine A1 receptors (A1Rs). It has been hypothesized that postsynaptic A2AR antagonists should be useful in Parkinson's disease, while presynaptic A2AR antagonists could be beneficial in dyskinetic disorders, such as Huntington's disease, obsessive-compulsive disorders and drug addiction. The aim or this work was to determine whether selective A2AR antagonists may be subdivided according to a preferential pre- versus postsynaptic mechanism of action. The potency at blocking the motor output and striatal glutamate release induced by cortical electrical stimulation and the potency at inducing locomotor activation were used as in vivo measures of pre- and postsynaptic activities, respectively. SCH-442416 and KW-6002 showed a significant preferential pre- and postsynaptic profile, respectively, while the other tested compounds (MSX-2, SCH-420814, ZM-241385 and SCH-58261) showed no clear preference. Radioligand-binding experiments were performed in cells expressing A2AR-D2R and A1R-A2AR heteromers to determine possible differences in the affinity of these compounds for different A2AR heteromers. Heteromerization played a key role in the presynaptic profile of SCH-442416, since it bound with much less affinity to A2AR when co-expressed with D2R than with A1R. KW-6002 showed the best relative affinity for A2AR co-expressed with D2R than co-expressed with A1R, which can at least partially explain the postsynaptic profile of this compound. Also, the in vitro pharmacological profile of MSX-2, SCH-420814, ZM-241385 and SCH-58261 was is in accordance with their mixed pre- and postsynaptic profile. On the basis of their preferential pre- versus postsynaptic actions, SCH-442416 and KW-6002 may be used as lead compounds to obtain more effective antidyskinetic and antiparkinsonian compounds, respectively.
