Lizards (Reptilia: Squamata) of the Corn Islands, Caribbean Nicaragua

Abstract: The Corn Islands are two small Caribbean islands with the richest collection of endemic herpetofaunal taxa in Nicaragua. Despite increasing human population and associated habitat alteration, both islands lack protected areas. The lizard fauna of Great Corn Island consists of 14 species corresponding to nine families, and includes three endemic taxa. We collected three lizard species ( Corytophanes cristatus , Gonatodes albogularis , and Hemidactylus frenatus ) that were not previously recorded from that island. On Little Corn Island, where there were no previous records of lizards, we found seven species ( Ctenosaura similis , Gonatodes albogularis , Hemidactylus frenatus , Holcosus undulatus , Iguana iguana , Lepidodactylus lugubris , and Norops unilobatus ), all of which are also present on Great Corn Island.

Hyperbaric oxygen therapy in wound healing in mice

Abstract: We investigated the local and systemic effects of hyperbaric oxygen therapy in BALB/C mice, exposed to two different exposure times, under 2.4 atmosphere (ATM). Fifteen animals were divided into three groups (GI, GII and Control) and underwent a surgical excision of a skin fragment of approximately one square centimeter of the dorsal region. The wounds were treated and monitored for 21 days. In the control group, the wound was cleaned once a day with sterile 0.9% NaCl solution. GI and GII mice were submitted to daily hyperbaric oxygen therapy of 30 or 60minutes sessions, respectively. The wounds were photographed every three days and their surfaces were analyzed by an image analyzer. At 21 days, all animals were euthanatized for histopathological analysis of the skin, lungs and liver in order to identify eventual alterations in wound healing or in the analyzed organs. Animals belonging to GI showed a faster skin wound healing in comparison to the other groups. Animals from GII, however, showed a delayed wound healing process and exhibited lung and microcirculatory alterations. These findings allow us to conclude that the exposure time to the oxygen in hyperbaric environment is crucial and can help or disturb skin wound healing or even be deleterious to other organs.

Estimación de los precios de las acciones de Netflix, Inc., por medio del análisis de regresión exponencial

Abstract: El analisis de regresion lineal exponencial, es una herramienta sumamente importante en el mundo de las finanzas y la economia, con este analisis se pueden realizar proyecciones y pronosticos de una variable dependiente explicada por una variable independiente que presenten una relacion curvilinea. El objetivo del presente trabajo fue determinar una ecuacion que permitiera estimar los precios mensuales de las acciones de Netflix, Inc., por medio de un modelo de regresion lineal exponencial. Los coeficientes betas estimados para el modelo, de manera individual, fueron significativos tanto para el coeficiente de la base como para el del argumento, cuyos valores fueron de 57.8122 y 0.0333, respectivamente. La prueba global de significancia de los coeficientes betas, tambien fue estadisticamente significativa, presentando un valor

Uso y abuso de drogas entre estudiantes y su relacion con el maltrato durante la ninez en una universidad de Leon, Nicaragua

Abstract: Estudio exploratorio cuantitativo que examina la relacion entre el uso de drogas en estudiantes de una universidad en Leon, Nicaragua y su relacion con el maltrato durante la ninez. Se realizo un estudio de corte transversal con perspectiva bioecologica en 368 participantes, de los cuales 178 (48.4%) eran hombres y 190 (51.6%) mujeres estudiantes de una universidad de Leon. Entre los resultados se destaca que la negligencia se encontro en 54.6% de los participantes distribuidos por genero de igual forma (56.3% hombres y 53.2% mujeres). En relacion al abuso psicologico, este se represento en el 40.5%, siendo el 70 (39.3%) hombres y (79) 41.6% mujeres. El 54.1% de los participantes tenian padres que se han separado, 44.3% viven o han vivido en algun momento de su vida con un alcoholico, 28.8% han presenciado que a su madre o cuidadora fuese abusada, 26.1% han vivido o vive con un familiar con enfermedad mental, mientras que un 21.2% ha vivido con un drogadicto. Se puede concluir que el maltrato infantil es comun y que la negligencia es un evento cotidiano entre los participantes del estudio.
