Termas de la Garita is an academic project of the Design Workshop (Tropical Architecture Option) in the last year of the Architecture Major in the University of Costa Rica (UCR). This project was developed along with the Laboratory of Tropical Architecture (LAT) of the School, in order to have an effective control of the bioclimatic variables of the project, because it takes place in a warm-humid zone of Costa Rica.

Introduction: Worldwide Alzheimer Disease Organization in the year 2012 carried out a campaign to overcome the stigma to dementia. The stigma constitutes the biggest obstacle to identify health's problems of, to find its solutions and to use in a more efficient way the health's services. Objective: To show it repercussion of the stigma to the patient with dementia, the family and the society. Material and Methods: It was carried out a search of the published literature in the period comprised from July 2010 until March 2016. The information was obtained through Infomed information network, we used the following databases, Pubmed, Ebsco, Medline, Sciencedirect, Clinicalkey and Scielo. The data obtained was analyzed and commented. Development: The stigma interferes in that people with dementia have a successful social life, obtain employments and to have the possibility to live near other people. It has a big relationship with the age and the loss of the mental functions. The areas of bigger impact of the stigma are: the labor sphere, vehicles driving, the possibility to give consent for the medical procedure that have influence in a premature loss of dignity and autonomy. Conclusions: To overcome the stigma that today exists to dementia it is necessary to offer a bigger acceptance and support to the patients and family, to increase care's quality for people with cognitive deterioration, to educate the population, to create a favorable environment, to create social network of support and to call the for participation of all the sectors of the society. Keywords: social stigma, dementia, social discrimination, health plan, family, society, Cuba.

Introduction: Kidney disease is a world health problem. Epidermic Growth Factor acts as cyto-protector, and trophic restorative. Objective:  To assess the reno-protective and reno-restorative effect of the Epidermal Growth Factor in biomodel of Chronic Renal Failure. Material and Methods: 120 Wistar rats were studied in 6 groups: Negative and Positive Control, Saline Solution Single-Dose and Multiple-Dose, Epidermal Growth Factor Single-Dose and Multiple-Dose.  A single dose was applied before the damage for the reno-protective effect, and multiple doses after the damage for the reno-restorative effect, at a rate of 100 µg/kg of weight. Results: Creatinine, urea, and uric acid diminished significantly in the experimental groups, with a higher decrease for experimental group with single dose; therefore, the reno-protective effect was higher than reno-restorative one for the treatment patterns used. Conclusions:  Epidermal Growth Factor showed reno-protective and reno-restorative effect by diminishing the hematological variables in kidney damage.Keywords:  Epidermal Growth Factor, reno-protective, reno-restorative, Chronic Renal Failure, 5/6 renal ablation.

In assessing the health of rivers, the standardization of environmental and biological information as a baseline is essential in order to determine the set of conditions that are closest to the natural state of ecosystems. This is the case especially in peri-urban rivers where anthropogenic transformations occur rapidly and constantly. The objective of this work was to determine hydromorphological, physicochemical and biological parameters in 10 mountain rivers of the Mexico Basin, in order to establish a network of potential reference conditions and to validate the regional ecological quality. The potential reference conditions in this study are defined as oligotrophic water bodies with well-oxygenated concentrations and low ion concentrations. These conditions were recorded in 4 sub-basins with high hydromorphological quality. These results were corroborated through a base assembly composed of the macroinvertebrate families Baetide, Chrironomidae, Dugesiidae, Heptageniidae, Limnephilidae, Tipulidae and the class Arachnida (Acarina). The algal community was represented by Nostoc parmelioides, Placoma regulare, Batrachospermum gelatinosum, Paralemanea mexicana, Draparnaldia mutabilis, Prasiola mexicana and Vaucheria bursata. The major disturbances were structural changes in the riverbed that affect the structure and function of rivers.

High species diversity renders benthic diatoms that are useful in assessing environmental impact, as well as an adequate reference for measuring biodiversity in protected areas. Preliminary observations suggested that the Guerrero Negro Lagoon (LGN), located in the Baja California Peninsula, Mexico, is an area with a high diversity of benthic diatoms comprising numerous species of certain genera, orders, class, etcetera, which were not equally diverse or common in other areas, and could thus yield new records for the region. Thus, samples of subtidal sediments from LGN were collected in order to analyze the species composition of epipelic diatoms by means of optical microscopy. The taxonomic study yielded a list with 232 taxa, which comprised 42 centric diatoms (>18%) and 190 pennates from 74 genera; 14 new records for the Mexican Pacific are included. This supported the hypothesis that epipelic diatoms from the LGN subtidal constitute assemblages with a high species richness and numerous taxa characteristic of subtropical regions.

Los murciélagos representan un componente clave en la dinámica de ecosistemas terrestres y alcanzan altos niveles de abundancia y diversidad en el neotrópico. Las transformaciones medioambientales modulan la diversidad alfa, beta y gamma de una región, donde algunas especies se ven favorecidas y otras no, reduciendo o ampliando su presencia regional; además, constantemente se genera nueva información sistemática y es necesaria la actualización de la nomenclatura en los listados faunísticos, información básica para los programas de manejo ambiental, por ello, presentamos una lista actualizada de los murciélagos de la Reserva de la Biosfera Los Tuxtlas. El listado está basado en capturas de campo, revisión de ejemplares depositados en colecciones científicas, así como en una revisión documental de bases nacionales e internacionales. De esta manera, se confirma la presencia de 65 especies de murciélagos y se descartan 8 especies probables aún no confirmadas en la región, pero que se han mencionado en diferentes fuentes.

El género Hydnotrya comprende alrededor de 13 especies de Ascomicetos hipogeos, secuestrados ectomicorrízicos distribuidos exclusivamente en bosques templados del hemisferio norte. En este trabajo se describe e ilustra por primera vez una especie de este género, Hydnotrya cerebriformis, para México. Esta especie se distribuye en el Eje Neovolcánico Transmexicano (Estado de México, Puebla y Tlaxcala) y Nuevo León a altitudes entre los 3,100 y 4,000 m, donde se asocia a bosques de Pinus hartwegii, P. montezumae y Abies religiosa, principalmente.

Las comunidades de hongos ectomicorrízicos presentes en las zonas montañosas de México han sido poco estudiadas. En este trabajo se caracterizaron morfológica y genéticamente las ectomicorrizas asociadas a un bosque de Pinus hartwegii en el Parque Nacional Cofre de Perote. El estudio se realizó en 3 sitios de muestreo, se trazaron 4 transectos de 500 m en cada sitio y se recolectaron 3 muestras de suelo cada 100 m. Se extrajo el ADN de las ectomicorrizas, se amplificó y secuenció la región de los ITS. La identidad taxonómica de los hongos se obtuvo por su similitud nucleotídica contra las secuencias depositadas en GenBank. Se describen 14 morfotipos, entre los que se encuentran: Piloderma olivaceum, Cortinarius diasemospermus, C. mucosus, Hydnellum concrescens, Russula aff. betularum, Sebacina vermifera y Sistotrema confluens y los géneros Byssocorticium y Pseudotomentella. Estos hongos ectomicorrízicos tienen un alto potencial en planes de reforestación pues pueden favorecer la sobrevivencia de plántulas, ya que están adaptados a las condiciones ambientales locales.

This study presents a coproparasitological survey of free-ranging jaguars (Panthera onca) and pumas (Puma concolor) inhabiting 2 types of tropical forest in southeastern Mexico. We examined 167 fecal samples (68 = jaguar; 33 = puma; 66 = unidentified large felids), and identified 16 parasitic taxa, 56% of which were nematodes. We compared parasite community composition and prevalence between host species and forest types, and found that parasitic communities of jaguar and puma were more similar between host species in the same forest type than among conspecific hosts inhabiting different forest types. Possible determinants for the observed patterns could include ecosystem differences and host evolutionary history, as well as disparate diet and habitat use of these 2 felines. Further studies are needed for a more accurate estimation of the parasitic community composition of these felines, and for a better comprehension of the effects that habitat perturbation could have on the ecology and transmission of parasitic diseases, and the related consequences for the conservation of wild felines.
