Listado florístico de especies anuales de floración invernal en el noreste de Nuevo León, México

RESUMEN La provincia fisiográfica Gran Llanura de Norteamérica en el noreste de Nuevo León, desde el punto de vista florístico ha sido la menos estudiada en el estado. En este estudio se presenta una lista preliminar de las especies anuales que florecen de diciembre a marzo, basada en trabajo de campo y revisión de las colecciones en los herbarios TEX/LL y UNL. Se incluyen 73 especies, de las cuales 85% son nativas y el 15% restante son introducidas. Once especies (15%) se consideran malezas invasoras o nocivas en alguna parte de Norteamérica. Aunque muchas de las especies son ruderales, el conjunto de especies es variado y su importancia biológica y ecológica como componente de la vegetación nativa es desconocida. Nueve especies son registradas como nuevas para la flora de Nuevo León. Este estudio demuestra que la flora de esta región esta imperfectamente documentada ABSTRACT The northeastern part of Nuevo León falls within the North American Great Plains physiographic province and it has been floristically the poorlest studied portion of the state. This study presents a preliminary list of the annual species that flower from December through March, based on field work and review of collections in the TEX/LL and UNL herbaria. Seventy three species are included, of which 85% are native and the rest (15%) are introduced. Eleven species (15%) are considered invasive or noxious weeds in some part of North America. Although many of the species are ruderals, the total group is varied and its biological and ecological importance as a part of the native vegetation is unknown. Nine species are reported as new for the flora of Nuevo León. This study shows that the flora in the region is imperfectly documente

Case Report: Formation of 3D Osteoblast Spheroid Under Magnetic Levitation for Bone Tissue Engineering

Skeletal reconstruction is necessary in cases of bone defects created by tumors, trauma, and abnormalities. Regeneration of bone defects remains a critical problem, and current approaches are based on biocompatible scaffolds. Spheroids represent a simple 3D system since no supporting material is required for cell growth. Different techniques are used to generate spheroids, such as hanging drop, low-attachment plates, and magnetic nanoparticles. The idea of using magnetic nanoparticles is to cross-link through cell membrane overnight to create complex 3D cellular spheroid by using magnets to guide the cellular response. Herein, the current study aimed to achieve 3D human fetal osteoblast (hFOB) spheroid under magnetic levitation. Formation of 3D spheroid culture under magnetic levitation was evaluated by cell viability at 3, 7, and 14 days. Morphology of the 3D hFOB spheroid was analyzed by SEM and fluorescence microscopy and the differentiation towards mineralized lineage by ALP assay, qPCR, and alizarin red staining. The cell viability indicated that the 3D hFOB spheroid still viable after 14 days of culture. ALP assay, qPCR analysis expression of Col1, ALP, and Itg-β1 molecules, and calcium deposition with alizarin red showed a high level of bioactivity of the 3D hFOB spheroid. SEM images allowed the morphological analysis of the 3D microtissue-like spheroid with the presence of matrix deposition. These results indicate that magnetic levitation culture enables 3D stable osteoblast spheroids and could be a promising strategy for engineering application in the 3D construct in surgery regeneration of mineralized tissue

Variation in Colonoscopy Performance Measures According to Procedure Indication

BACKGROUND & AIMS: Most fulfillment and benchmarking information for colonoscopy quality indicators has been obtained from studies of primary screening colonoscopies. We analyzed differences in the fulfillment of colonoscopy quality indicators based on the indication for endoscopy. METHODS: We performed an observational, multicenter, cross-sectional study of 14,867 patients who underwent endoscopy procedures for gastrointestinal symptoms (40.3%), a positive result from a fecal immunochemical test (36.0%), postpolypectomy surveillance (15.3%), or primary screening (8.4%), from February 2016 through December 2017 at 14 centers in Spain. We evaluated rates of adequate colon cleansing, cecal intubation, adenoma detection, and colorectal cancer detection, among others. We used findings from primary screening colonoscopies as the reference standard. RESULTS: Fewer than 90% of patients had adequate bowel preparation; 83.1% of patients with gastrointestinal symptoms had adequate bowel preparation (odds ratio [OR] compared with patients with primary screening colonoscopies, 0.62; 95% CI, 0.49–0.78) and 85.3% of patients receiving postpolypectomy surveillance had adequate bowel preparation (OR, 0.71; 95% CI, 0.55–0.91). The cecal intubation rate was also lower in patients with gastrointestinal symptoms (93.1%) (OR, 0.34; 95% CI, 0.22–0.52). The adenoma detection rate was higher in patients with a positive result from a fecal immunochemical test (46.4%) (OR, 2.01; 95% CI, 1.71–2.35) and in patients undergoing postpolypectomy surveillance (48.2%) (OR, 1.41; 95% CI, 1.20–1.67). The highest proportion of patients with colorectal cancer was in the gastrointestinal symptom group (5.1%) (OR, 5.24; 95% CI, 2.30–11.93) and the lowest was in patients undergoing surveillance (0.8%) (OR, 0.83; 95% CI, 0.32–2.14). CONCLUSIONS: Fulfillment of colonoscopy performance measures varies substantially by indication. Policies addressing performance measures beyond colonoscopy screening procedures should be developed. Benchmarking recommendations could be adjusted according to colonoscopy indication

Factors associated with lesion detection in colonoscopy among different indications

Background and objective: Different factors may influence colonoscopy performance measures. We aimed to analyze procedure- and endoscopist-related factors associated with detection of colorectal lesions and whether these factors have a similar influence in the context of different colonoscopy indications: positive fecal immunochemical test (+FIT) and post-polypectomy surveillance colonoscopies. Methods: This multicenter cross-sectional study included adults aged 40-80 years. Endoscopists (N = 96) who had performed ≥50 examinations were assessed for physician-related factors. Adenoma detection rate (ADR), adenomas per colonoscopy rate (APCR), advanced ADR, serrated polyp detection (SDR), and serrated polyps per colonoscopy rate (SPPCR) were calculated. Results: We included 12,932 procedures, with 4810 carried out after a positive FIT and 1967 for surveillance. Of the 96 endoscopists evaluated, 43.8% were women, and the mean age was 41.9 years. The ADR, advanced ADR, and SDR were 39.7%, 17.7%, and 12.8%, respectively. Adenoma detection rate was higher in colonoscopies after a +FIT (50.3%) with a more than doubled advanced ADR compared to non-FIT procedures (27.6% vs. 13.0%) and similar results in serrated lesions (14.7% vs. 13.5%). Among all the detection indicators analyzed, withdrawal time was the only factor independently related to improvement (p < 0.001). Regarding FIT-positive and surveillance procedures, for both indications, withdrawal time was also the only factor associated with a higher detection of adenomas and serrated polyps (p < 0.001). Endoscopist-related factors (i.e., weekly hours dedicated to endoscopy, annual colonoscopy volume and lifetime number of colonoscopies performed) had also impact on lesion detection (APCR, advanced ADR and SPPCR). Conclusions: Withdrawal time was the factor most commonly associated with improved detection of colonic lesions globally and in endoscopies for + FIT and post-polypectomy surveillance. Physician-related factors may help to address strategies to support training and service provision. Our results can be used for establishing future benchmarking and quality improvement in different colonoscopy indications

Ingeniería Forestal y ambiental en medios insulares

Las Islas Canarias a pesar de su reducida extensión y del relativo poco peso específico a nivel mundial, no es ajena a los problemas globales detectados en la conservación de bosques y en la importancia que éstos tienen para obtener beneficios económicos, socioculturales y ambientales. La gestión forestal sostenible es en este sentido esencial para asegurar y compatibilizar los diversos beneficios del bosque. El papel específico de los bosques y su gestión son sin embargo temas aún por conocer en nuestras islas, por lo que el Año Internacional de los Bosques ha representado una oportunidad única para dar a conocer el mundo forestal y acercarlo a nuestra sociedad. El presente libro consta de 25 capítulos donde se ha contemplado la mayoría de los aspectos a tener en cuenta en la planificación y gestión del medio forestal y natural. Desde la historia forestal del archipiélago, hasta el uso y técnicas de manejo de los recursos naturales, incluyendo el agua, la energía en forma de biomasa y la selvicultura

Practical guideline for Benign paroxismal positional vertigo

Introduction and objective: Benign paroxysmal positional vertigo (BPPV) is the most common peripheral vertigo, characterized by brief attacks of rotatory vertigo associated with nystagmus, which are elicited by specific changes in head position relative to gravity. The observation of positional nystagmus is essential for the diagnosis of BPPV. The treatment consists in maneuvers of canalith repositioning procedure to move otoconial debris from the affected semicircular canal to the utricle. These guidelines are intended for all who treat the BPPV in their work, with an intention to assist in the diagnosis and application of an appropriate therapeutic method. Method: The experience and analysis of different national and international consensus on BPPV, has allowed to a large group of ENT specialists of the Communities of Castilla y León, Cantabria and La Rioja (Spain), carry out this guide. Results: The different clinical entities are reviewed. BPPV of the posterior semicircular canal, horizontal canal and anterior canal, BPPV affecting several canals, atypical and central BPPV, subjective BPPV and the characteristics of this process in the elderly. Canalith repositioning procedures have been illustrated with explanatory drawings. Discussion and conclusions: Although the pathophysiology of BPPV is canalolithiasis comprising free-floating otoconial debris within the endolymph of a semicircular canal, or cupulolithiasis comprising otoconial debris adherent to the cupula, there are still many issues to be resolved. We think that the best way to find answers is part of using a common methodology in the diagnosis and treatment of these patients.Introducción y Objetivo: El vértigo periférico más frecuente es el Vértigo Posicional Paroxístico Benigno (VPPB), caracterizado por bruscos ataques de sensación rotatoria, que aparecen como consecuencia de determinados cambios en la posición de la cabeza con relación a la gravedad. La observación del nistagmo posicional es fundamental para el diagnóstico de VPPB. El tratamiento consiste en aplicar maniobras de reposición, para intentar trasladar los restos otoconiales libres, desde el conducto semicircular (CS) afectado hasta el utrículo. Esta guía, está orientada para quienes tratan el VPPB, con la intención práctica de ayudarles en el diagnóstico y tratamiento de esta enfermedad. Método: La experiencia y el análisis de diferentes acuerdos nacionales e internacionales sobre el VPPB, han permitido a un amplio grupo de especialistas ORL de las Comunidades de Castilla y León, Cantabria y La Rioja (España), llevar a cabo esta guía. Resultados: Se revisan las diferentes entidades clínicas. VPPB del conducto semicircular posterior (CSP), horizontal (CSA) y anterior (CSA), incluyéndose también el VPPB multicanal, VPPB atípico y central, VPPB subjetivo y las características de este proceso en el anciano. Las maniobras de reposición se han ilustrado con dibujos explicativos. Discusión y conclusiones: Aunque la fisiopatología del VPPB se explica por la presencia de restos otoconiales libres en la endolinfa de uno o varios conductos semicirculares (canalitiasis) y en algunos casos por su adherencia a la cúpula del CS (cupulolitiasis), aún quedan muchas cuestiones por resolver. Pero creemos que la mejor manera de encontrar respuestas parte de utilizar una metodología común en el diagnóstico y tratamiento de estos pacientes
