PROCESOS DE DEFORESTACIÓN Y REDUCCIÓN DE DENSIDAD DEL ARBOLADO DEL PARQUE NACIONAL NEVADO DE TOLUCA

Históricamente las áreas naturales de alta montaña en México han sufrido de presión a sus recursos naturales provocados por diversos factores como la extracción de recursos maderables y las plagas y enfermedades. Los intentos de zonificación resultan muy generalistas y se hace imposible hacer una evaluación de las transiciones menores de 10 años, debido a que los procesos necesarios para su evaluación suponen una elevada inversión en tiempo para tener un producto detallado y funcional. Para el Parque Nacional Nevado de Toluca se elaboró un mapa de ocupación del suelo para 2009 con una imagen SPOT basado en la categorización Cetenal de uso de suelo y vegetación escala 1:50 000 para 1972 y se contrastó con la más reciente actualización para el año 2000 como referencia. Se realizó una sobreposición de los mapas de ocupación del suelo para los años 2000 y 2009 para hacer la interpretación interactiva por sectores de las transiciones en el periodo de estudio. Así se obtuvieron las áreas en donde se ha verificado deterioro en terrenos forestales. Las áreas con mayor dinámica negativa son los bosques de pino, por efectos de deforestación y de pérdida de densidad del arbolado. Se calculó una tasa general de 35 ha año-1, contra solo 3 ha año-1 de bosques recuperados. Se concluye que el área natural protegida está sujeta a intensos procesos de tala selectiva de manera ilegal o por saneamiento

Experimental-Theoretic Approach to Drug-Lymphocyte Interactome Networks with Flow Cytometry and Spectral Moments Perturbation Theory

Modelos matematicos y citometria de flujoAbstract: We can combine experimental techniques like Flow Cytometry Analysis (FCA) with Chemoinformatics methods to predict the complex networks of interactions between organic compounds and targets in the immune system. In this work, we determined experimentally the values of EC50 = 17.82 μg/mL and Cytotoxicity = 20.6 % for the antimicrobial / anti-parasite drug Dermofural over Balb/C CD9 lymphocytes using flow cytometry. After that, we developed a new Perturbation-theory model for Drug-Cell Target Interactome in Lymphocytes based on dispersion-polarization moments of drug structure. The models correctly classifies 34591 out of 42715 (Accuracy = 80.9%) cases of perturbations in assay endpoints of 11492 drugs (including both train and validation series). Each endpoint correspond to one out of 2616 assays, 38 molecular and cellular targets, 77 standard type measures, in four possible (human and rodentsCONACY

Molecular findings of colombian patients with type VI mucopolysaccharidosis (Maroteaux-Lamy syndrome)

Q483-89Introduction: Maroteaux–Lamy syndrome, or mucopolysaccharidosis (MPS) type VI, is an autosomal recessive lysosomal storage disease caused by a deficient activity of the enzyme arylsulfatase B (ARSB), required to degrade dermatan sulfate. The onset and progression of the disease vary, producing a spectrum of clinical presentation. So far, 133 mutations have been reported. The aim of this study is to determine the mutations in the ARSB gene that are responsible for this disease in Colombian patients. Results: Fourteen patients with clinical manifestations and biochemical diagnosis of MPS VI were studied, including two siblings. The 8 exons of the gene were directly sequenced from patients' DNA, and 14 mutations were found. 57% of these mutations had not been previously reported (p.H111P, p.C121R, p.G446S, p.*534W, p.S334I, p.H147P, c.900TNG, and c.1531_1553del) and 43% had been previously reported (p.G144R, p.W322*, p.G302R, p.C447F, p.L128del, and c.1143-1GNC). Of the previously reported mutations, 80% have been associated with severe phenotypes and 20% with intermediate-severe phenotypes. Bioinformatic predictions indicate that the new mutations reported in this paper are also highly deleterious. Conclusions: Most of the Colombian patients in this study had private mutations

Technology tools, including software and websites, which facilitate the translation of different documents from english to spanish and from spanish to english.

It is well known that translation is the process of transferring a text from a source language into the target language. The following text is to summarize how essential the translation process is when having the ability of speaking more than one language. It is essential to consider the use of specific tools in order to keep the original meaning of each document, to reach this result many techniques can be use. By following the instruction from the techniques and tools, these techniques have been proposed in order to be accurate at the moment to adapt the source language. In relation to translation, this does not mean converting the text by a human being. It is also focusing on the tools which the translator can use. Everyone should focus on how translation is playing a big role in the world; this is making the difference. Taking into consideration that nowadays all books are written in a source language, these tools are going to be helpful since the largest documents can be translated in an accurate way. To conclude about translation which is one of the most common processes since these techniques will facilitate people at the moment to communicate. Translation methods relate to whole texts, translation procedures are used for sentences and the smaller units of language. These methods give the choice and opportunity to engage people to keep learning and discovering other languages.

Optimizing space telescopes’ thermal performance through uncertainty analysis: identification of critical parameters and shaping test strategy development

The integration of uncertainty analysis methodologies allows for improving design efficiency, particularly in the context of instruments that demand precise pointing accuracy, such as space telescopes. Focusing on the VINIS Earth observation telescope developed by the Instituto de Astrofísica de Canarias (IAC), this paper reports an uncertainty analysis on a thermal model aimed at improving cost savings in the future testing phases. The primary objective was to identify critical parameters impacting thermal performance and reduce overdesign. Employing the Statistical Error Analysis (SEA) method across several operational scenarios, the research identifies key factors, including the Earth’s infrared temperature and albedo, and the spacecraft’s attitude and environmental conditions, as the variables with major influences on the system’s thermal performance. Ultimately, the findings suggest that uncertainty-based analysis is a potent tool for guiding thermal control system design in space platforms, promoting efficiency and reliability. This methodology not only provides a framework for optimizing thermal design and testing in space missions but also ensures that instruments like the VINIS telescope maintain optimal operating temperatures in diverse space environments, thereby increasing mission robustness and enabling precise resource allocation.Agencia Estatal de Investigación | Ref.

Pilot study of the characteristics of acute stroke events in patients discharged from the Carolina University Hospital, Puerto Rico in 2007

BACKGROUND: Stroke is the third leading cause of death in Puerto Rico. We examined the pre-hospital phase, management and case-fatality-rates (CFR) of patients discharged with acute stroke from the Carolina University of Puerto Rico Hospital during 2007. METHODS: Trained personnel collected information on demographics, delay-time, mode-of-transportation, management, and mortality from all medical records. STATAa was utilized to conduct univariate comparison of demographics, mode-of-transportation, therapeutics and diagnostic characteristics. Logistic regression analysis assessed cohort effect and controlled for confounders. RESULTS: The average age was 69.1 years, and 53% were males. The average delay between onset of symptoms suggestive of stroke and arrival at the emergency department was 4.5 hours. Only 62% of patients utilized Emergency Medical Services (EMS). Intravenous thrombolysis was not administered. Stroke mortality increased with age. Ischemic vs. hemorrhagic CFR was significantly higher (63.9% vs. 36.10%; p = 0.034). CONCLUSIONS: These findings highlight the potential benefit of evidence-based therapeutics and EMS use among stroke patients
