Homogeneity test for functional data based on depth measures

In the context of functional data analysis, we propose a new method to test the homogeneity of families of functions. Based on some well-known depth measures, we construct four different statistics in order to measure distance between the two families. A simulation study is performed to check the efficiency of the testswhen confronted with shape and magnitude perturbation. Finally, we apply these tools to measure the homogeneity in some families of real data, obtaining good results for these new methods

Comparison of early complications using regular mesh versus Atramat® Neoflex 25 mesh in inguinal, umbilical and post incisional hernias

Background: Hernias are one of the most common reasons of primary health care with subsequent surgery and this has led to search new techniques to approach them. Comparing traditional techniques with polypropylene mesh versus one bioabsorbible mesh there has been a decrease in postoperative complications.Methods: 100 patients with inguinal hernia, umbilical and post incisional were surgically intervened and divided into two groups according to mesh material used. The patients were tracked for two months after surgery.Results: Traditional mesh was used to repair hernias in 50 patients and Atramat® Neoflex 25 mesh was used in the other half.  Two patients developed infection with traditional mesh and one patient using Atramat® Neoflex 25 mesh (p 0.558). Hernias recurred in 4 patients with traditional mesh compared with 0 patients with Atramat® Neoflex 25 mesh ( p.041 ) , seroma formation was found with a 6: 1 ratio, traditional mesh: Atramat® Neoflex 25 mesh ( p.050 ) and hematoma in a 2:1 ratio (p .558). The total of complications showed a total of 14 using traditional mesh and 3 with Atramat® Neoflex 25 mesh. The use of mesh made from absorbable materials is a better alternative to reduce chronic pain and recurrence due to its high biocompatibility.Conclusions: Using Atramat® Neoflex 25 mesh demonstrated a significant reduction of complications (recurrence and seroma formation) and length of hospital stay (2 days vs 1 day in abdominoplasty after surgery).   

Acute abdomen secondary to dependent rectus sheath hematoma: a case report

The rectus sheath hematoma as a rare clinical entity and self-limited, resulting from the accumulation of blood within the sheath of the rectus abdominis, secondary to breakage the epigastric artery higher or lower, or direct damage by fiber tear of rectus abdominis muscle. Female patient, 37 years old, enters the service of emergencies by refer abdominal pain of sudden onset, diffuse, with 5 hours of evolution with irradiation to lumbar region ipsilateral. In the CT scan in single stage and with IV contrast, it was reported an asymmetry in the thickness of the muscles of the anterior wall at the expense of a lesion of occupying space dependent anterior rectus muscle, as diagnostic impression is concluded a intramuscular injury dependent of the right anterior abdominal straight; likely bruising of the sheath of the straight abdominal by what is being decided its income to operating room to perform surgical drainage and epigastric vessel ligation. for the general doctor, specialist and it is important to take into account the pathology, symptoms, diagnostic and therapeutic strategy for a hematoma dependent of the rectus abdominis muscle, due to the high percentage of error diagnosis in patients who are admitted to the emergency department with acute abdominal pain, because you can Confused with other abdominal pathologies, which shows the importance of an appropriate differential diagnosis, and treatment prescribed, which optimize and reduce unnecessary intervention as well as morbidity and mortality of this disease

Lo glocal y el turismo. Nuevos paradigmas de interpretación.

El estudio del turismo se realiza desde múltiples escalas y enfoques, este libro aborda muchos temas que es necesario discutir desde diversas perspectivas; es el caso de la reflexión sobre la propia disciplina y sus conceptos, así como los asuntos específicos referidos al impacto territorial, los tipos de turismo, las cuestiones ambientales, el tema de la pobreza, la competitividad, las políticas públicas, el papel de las universidades, las áreas naturales protegidas, la sustentabilidad, la cultura, el desarrollo, la seguridad, todos temas centrales documentados y expuestos con originalidad y dominio del asunto. Lo multiescalar es básico para la comprensión del sistema turístico, sistema formado de procesos globales, regionales y locales. El eje de discusión del libro es lo glocal, esa interacción entre lo nacional y local con lo global

Behavior of Mesenchymal Stem Cells Obtained From Dental Tissues: A Review of the Literature

The success of tissue engineering in combination with tissue regeneration depends on the behavior and cellular activity in the biological processes developed within a structure that functions as a support, better known as scaffolds, or directly at the site of the injury. The cell-cell and cell-biomaterial interaction are key factors for the induction of a specific cell behavior, together with the bioactive factors that allow the formation of the desired tissue. Mesenchymal Stem Cells (MSC) can be isolated from the umbilical cord and bone marrow; however, the behavior of Dental Pulp Stem Cells (DPSC) has been shown to have a high potential for the formation of bone tissue, and these cells have even been able to induce the process of angiogenesis. Advances in periodontal regeneration, dentin-pulp complex, and craniofacial bone defects through the induction of MSC obtained from tooth structures in in vitro-in vivo studies have permitted the obtaining of clinical evidence of the achievements obtained to date.El éxito de la ingeniería de tejidos en combinación con la regeneración de tejidos depende del comportamiento y la actividad celular en los procesos biológicos desarrollados dentro de una estructura que funciona como soporte mejor conocida como andamio o directamente en el sitio de la lesión. La interacción célula-célula y célula-biomaterial son factores claves para la inducción a un comportamiento celular específico junto con factores bioactivos que permitan la formación del tejido deseado. Las células troncales mesenquimales (MSCs) pueden ser aisladas del cordón umbilical y de la medula ósea, sin embargo, el comportamiento de las células troncales de pulpa dental (DPSCs) han demostrado tener un alto potencial para la formación de tejido óseo e incluso han logrado inducir el proceso de angiogénesis. Avances en la regeneración periodontal, complejo dentino-pulpar y defectos óseos craneofaciales a través de la inducción de MSCs obtenidas de estructuras de dientes en estudios in vitro-in vivo han permitido obtener evidencia clínica de los logros obtenidos hasta el momento

The synthesis of transparent TiO2 photoelectrodes assisted by rheological agent (triton x-100, PVP and F-127) for dye sensitized solar cells

In this work, the transparent TiO2 photoelectrodes have been synthesized by the sol–gel method and the dip-coating technique, incorporating three rheological agents as porous template – Triton X-100, polivinilpirrolidone (M.W. 10000) and Pluronic F-127 into the TiO2 sol for the application in dye- -sensitized solar cells. Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, m-lines and UV–Vis spectroscopy analyses were carried out to examine the chemical composition, structure, morphology, thickness and optical transmittance of the TiO2 photoelectrodes. Impedance spectroscopy was carried out to analyze the cells’ behaviour. An average energy conversion efficiency of 1.04 % was achieved using triton as a modifier of the transparent TiO2 film, obtaining a thickness about 1.21 μm, a crystallite size of about 7 nm in the anatase phase and the porosity of about 53.4 %. Triton proved to be efficient for obtaining transparent and porous semiconductor films, while increasing the photoelectrochemical device’s performance
