Abstract:
Penetrating brain injury due to low energy objects is an unusual cause of head trauma, unlike gunshot wounds. Most cases reported are noteworthy due to its large dimension and, sometimes, good functional outcome. The present report describes the case of a Brazilian man presenting with a deep penetrating brain injury by a harpoon and no neurologic deficits. We discuss the main mechanisms of trauma and make a brief review of the literature upon epidemiological aspects and possible therapeutic approach. The early and appropriate neurosurgical management, on experience hands, may improve considerably patient outcome.

Abstract:
ABSTRACT:Guillaume-Benjamin-Amand Duchenne was born 200 years ago in Boulogne-sur-Mer (Pas-de-Calais, France). He studied medicine in Paris and became a physician in 1831. He practiced general medicine in his native town for about 11 years and then returned to Paris to initiate pioneering studies on electrical stimulation of muscles. Duchenne used electricity not only as a therapeutic agent, as it was commonly the case earlier in the 19th century, but chiefly as a physiological investigation tool to study the anatomy of the living body. Without formal appointment he visited hospital wards across Paris searching for rare cases of neuromuscular disorders. He built a portable electrical device that he used to functionally map all bodily muscles and to study their coordinating action in health and disease. He gave accurate descriptions of many neuromuscular disorders, including pseudohypertrophic muscular dystrophy to which his name is still attached (Duchenne muscular dystrophy). He also invented a needle system (Duchenne's histological harpoon) for percutaneous sampling of muscular tissue without anesthesia, a forerunner of today's biopsy. Duchenne summarized his work in two major treatises entitled De l'électrisation localisée (1855) and Physiologie des mouvements (1867). Duchenne's iconographic work stands at the crossroads of three major discoveries of the 19th century: electricity, physiology and photography. This is best exemplified by his investigation of the mechanisms of human physiognomy in which he used localized faradic stimulation to reproduce various forms of human facial expression. The album that complements his book on this issue is considered a true incunabulum of photography. Duchenne de Boulogne, a shy but hard-working, acute and ingenious observer, became one of most original clinicians of the 19th century. He died in Paris in 1875.

Abstract:
In the current study, we identified a transcription factor, MYB14, from Chinese wild grape, Vitis quinquangularis-Pingyi (V. quinquangularis-PY), which could enhance the main stilbene contents and expression of stilbene biosynthesis genes (StSy/RS) by overexpression of VqMYB14. The promoter of VqMYB14 (pVqMYB14) was shown to be induced as part of both basal immunity (also called pathogen-associated molecular pattern (PAMP)-triggered immunity, PTI) and effector-triggered immunity (ETI), triggered by the elicitors flg22 and harpin, respectively. This was demonstrated by expression of pVqMYB14 in Nicotiana benthamiana and Vitis. We identified sequence differences, notably an 11 bp segment in pVqMYB14 that is important for the PTI/ETI, and particularly for the harpin-induced ETI response. In addition, we showed that activation of the MYB14 promoter correlates with differences in the expression of MYB14 and stilbene pattern induced by flg22 and harpin. An experimental model of upstream signaling in V. quinquangularis-PY is presented, where early defense responses triggered by flg22 and harpin partially overlap, but where the timing and levels differ. This translates into a qualitative difference with respect to patterns of stilbene accumulation.

Abstract:
IntroductionMitral regurgitation (MR) is the most prevalent heart valve condition in Western countries. Open-heart mitral valve reconstruction is the conventional surgical treatment for MR, whereby the valve's cords are replaced with expanded polytetrafluoroethylene cords. Novel devices have introduced minimally invasive alternatives, such as transapical beating-heart valve repair. Among these alternatives, the Harpoon™ Mitral Valve Repair System (Edwards Lifesciences LLC) may have potential advantages (a smaller diameter valve introducer to minimize bleeding and a different anchoring mechanism). This study aimed to assess the efficacy and safety of Harpoon in minimally invasive mitral valve surgery.MethodsAn early assessment of the technology was conducted by reviewing relevant literature from the following databases: PubMed, EMBASE, Web of Science, the Trip Database, the International Clinical Trials Registry Platform, ClinicalTrials.gov, the Cochrane Library, and the Centre for Reviews and Dissemination. Relevant clinical studies published up to 30 January 2018 were included.ResultsOnly two publications, by the same research group, were included: an observational study of 11 patients and the prospective, nonrandomized TRACER trial (n = 30). During the procedure, MR was reduced from severe to none in 73 to 86 percent of patients and severe to mild in 14 to 27 percent. At one month, MR was rated as mild or lower in 82 to 89 percent of patients. At six months, MR had worsened to moderate or severe in 16 percent of patients from the TRACER trial. Safety issues within 30 days (18% to 27% of patients) included intraoperative conversion to open surgery, reoperation, pleural effusion, hemopericardium, and atrial fibrillation. There were no intra- or postoperative deaths.ConclusionsCurrent evidence on the Harpoon device is scarce. Although published studies showed improvement in MR in most patients, there are still issues regarding safety, lack of long-term results, comparability with other procedures, and costs. While promising, further research is required before recommending routine use of this technology.

Abstract:
In this thesis, we focused on the alternative methodologies that are based on the reconstruction of density matrices. While in DFT several benchmarks can be found in the literature, for the rest of alternative methodologies there were not any comprehensive benchmarks where the quality of the approximated reduce density matrices (RDMs) were analyzed. Thus, in this thesis, we have performed an exhaustive benchmark for the approximations available in the literature that reconstruct the 2- and 3-order RDMs. RDMs provide access to physical magnitudes as the intracule probability density (IPD). Actually, the radial IPD can be measured experimentally from X-Ray scattering; hence we focused on a deep understanding of this magnitude and, to that end, we analyzed the evolution of the radial IPD in isolated atoms and in the bond formation process. Finally, since RDMs also provide means to evaluate the bond order, we characterized the so-called harpoon mechanism
En esta tesis, nos enfocamos en metodologías alternativas que se basan en la reconstrucción de matrices de densidad. Mientras que en DFT varias calibraciones se pueden encontrar en la literatura, para el resto de metodologías alternativas no hay ninguna calibración donde la calidad de la matrices sea analizada. Por lo tanto, en esta tesis, desarrollamos una calibración exhaustiva para las aproximaciones disponibles en la literatura que reconstruyen matrices de orden 2 y 3. Las matrices densidad proporcionan acceso a magnitudes físicas como la densidad de probabilidad intracular (IPD). Nos centramos en una comprensión profunda de esta magnitud y, para ese fin, analizamos la evolución del IPD radial en átomos aislados y en el proceso de formación de enlaces. Finalmente, desde las matrices densidad también podemos evaluar el orden de los enlaces, y lo usamos para caracterizar el llamado mecanismo de arpón
