On spacelike surfaces in 4-dimensional Lorentz-Minkowski spacetime through a lightcone
Francisco J. Palomo,Alfonso Romero
Mathematics , 2012,
Abstract: On any spacelike surface in a lightcone of four dimensional Lorentz-Minkowski space a distinguished smooth function is considered. It is shown how both extrinsic and intrinsic geometry of such a surface is codified by this function. The existence of a local maximum is assumed to decide when the spacelike surface must be totally umbilical, deriving a Liebmann type result. Two remarkable families of examples of spacelike surfaces in a lightcone are explicitly constructed. Finally, several results which involve the first eigenvalue of the Laplace operator of a compact spacelike surface in a lightcone are obtained.

Veterinaria México , 1999,
Abstract: Este estudio se realizó con objeto de caracterizar los procesos neumónicos sufridos por becerras lecheras de Tijuana, Baja California, México, así como conocer la importancia relativa de los principales agentes bacterianos involucrados. En 12 establos, con distintos tipos de alojamientos para sus crías, se obtuvieron muestras pulmonares de un total de 100 becerras, de 15 días a 4 meses de edad, con antecedentes de haber padecido neumonía. La mayor parte de los problemas neumónicos se presentaron en granjas que alojaron a sus crías dentro de edificios, mientras que las que utilizaban casetas exteriores mostraron el menor índice de mortalidad ocasionado por neumonías. Las muestras pulmonares fueron sembradas por duplicado en agar sangre y agar chocolate, e incubadas a 37oC por 24 h en aerobiosis o microaerobiosis, respectivamente. Las bacterias aisladas fueron identificadas de acuerdo a los métodos bioquímicos rutinarios, utilizando cepas de referencia como control. Se aisló Pasteurella multocida en 34 animales, P. haemolytica en 31 casos y Haemophilus somnus en 11 ocasiones. Además se aislaron diversas bacterias consideradas como secundarias: Streptococcus spp en 12 casos y Staphylococcus spp en 7 animales. La totalidad de las cepas aisladas de P. multocida fueron clasificadas como del biotipo A, al igual que las 31 cepas de P. haemolytica. De estas últimas, 26 cepas (83.9%) se clasificaron como serotipo 1 y solamente 2 cepas se caracterizaron como serotipo 2, detectándose 3 cepas no tipificables.
Puesta al día sobre implantes de carga inmediata: Revisión bibliográfica

Abstract: the treatment of totally or partially edentulous patients with osseointegrated implants is an increasing part of daily dental practice. the greater aesthetic and functional demands made by these patients have created a constant pressure to reduce the waiting time before implants are loaded. in some cases, however, a shortening of the waiting period may compromise the osseointegration of the fixtures. the present review aims to inform the clinician about the continuing controversy on this issue. data from the reviewed studies allow comparisons to be made between the different success rates obtained after immediate implant loading, offering a more objective basis for our advice to patients on this type of treatment. according to our review, the type and quality of the bone and the surface of the implant are the factors that determine the selection of patients who can undergo the premature loading of implants.
Hsp90β inhibition modulates nitric oxide production and nitric oxide-induced apoptosis in human chondrocytes

Abstract: Human OA chondrocytes were isolated from cartilage obtained from patients undergoing joint replacement surgery, and primary cultured. Cells were stimulated with proinflammatory cytokines (IL-1β or TNF-α) and nitric oxide donors (NOC-12 or SNP). For Hsp90β inhibition, two different chemical inhibitors (Geldanamycin and Novobiocin) were employed, or siRNA transfection procedures were carried out. Gene expression was determined by real-time PCR, apoptosis was quantified by flow cytometry and ELISA, and nitric oxide (NO) production was evaluated by the Griess method. Indirect immunofluorescence assays were performed to evaluate the presence of Hsp90β in stimulated cells.Hsp90β was found to be increased by proinflammatory cytokines. Inhibition of Hsp90β by the chemicals Geldanamycin (GA) and Novobiocin (NB) caused a dose-dependent decrease of the NO production induced by IL-1β in chondrocytes, up to basal levels. Immunofluorescence analyses demonstrate that the NO donors NOC-12 and SNP also increased Hsp90β. Chemical inhibition or specific gene silencing of this chaperone reduced the DNA condensation and fragmentation, typical of death by apoptosis, that is induced by NO donors in chondrocytes.The present results show how Hsp90β modulates NO production and NO-mediated cellular death in human OA chondrocytes.Osteoarthritis (OA) is a slowly progressive degenerative disease characterized by the degradation of the extracellular matrix (ECM) and cell death, resulting in a gradual loss of articular cartilage integrity, intra-articular inflammation and changes in peri-articular and subchondral bone [1]. The chondrocyte is the only cell type present in mature cartilage and is responsible for repairing the cartilage tissue damaged by OA.Chondrocytes are key players in the control of cartilage matrix turnover through the production and secretion of collagens, proteoglycans, and enzymes affecting cartilage metabolism [2]. Chondrocyte metabolism is influenced by several cytokines an

Abstract: background: oculocardiac reflex is a very well-known phenomenon in the ophthalmologic surgery and since its discovery oculists and anesthesiologists consider it as a significant intraoperative problem, they describe dysrhythmia that caused morbidity and death. objective: to carry out a revision on anesthetic considerations in the face of oculocardiac reflex. method: a bibliographical revision on the topic, in which is approached anatomy, physiology, anesthetic particularities and treatment once it is presented. conclusions: the exhaustive knowledge of the occurrence of oculocardiac reflex caused benefit to patients underwent to the ophthalmologic surgery.

Abstract: On April 26-27, 2013, the Step by Step Foundation hosted the Second International Spinal Cord Repair Meeting at the Fira Barcelona Convention Center in Hospitalet de Llobregat, Spain, highlighting some of the exciting research including clinical trials which show promise for treatments for this devastating disorder. This meeting brought together clinicians, clinical scientists and molecular biologists from more than 10 countries to evaluate current knowledge on clinical, cellular, and biomolecular aspects of spinal cord injury. A major goal of the conference in advancing the translation of research data to the clinic was to promote multi-pronged approaches for therapy of this complex problem.
