La prensa en papel se ha visto afectada por la aparición de los medios digitales, por la bajada de audiencia, de venta de ejemplares y de ingresos publicitarios. Estos cambios han impactado en su modelo de negocio y perspectivas de futuro, dando si cabe un mayor poder a los ingresos procedentes de la venta de los espacios publicitarios. El objetivo principal de esta investigación es profundizar sobre los cambios que se han producido en los precios de los anuncios publicitarios de la prensa impresa en la última década (2013-2022) y analizar los futuros escenarios comerciales a los que se enfrenta el medio en los próximos años. Para ello, se ha empleado una metodología mixta. La parte cuantitativa se centra en el análisis de los precios de compra de los anuncios, mientras que la parte cualitativa se focaliza en las opiniones de los profesionales del sector que trabajan diariamente en la selección de los emplazamientos publicitarios para las marcas. Los resultados ponen de manifiesto un precio cada vez menor por el espacio publicitario en la prensa impresa, sobre todo en los diarios nacionales, a pesar de un aumento de las tarifas oficiales de los soportes. Asimismo, muestran un escenario comercial centrado en la especialización, la credibilidad y la seriedad del medio frente a la venta masiva de publicidad. Las conclusiones ponen de manifiesto las dificultades de la supervivencia del medio impreso con el sistema de financiación actual, pero les abre una vía para la realización de estrategias comerciales que refuercen las características que lo diferencian del online.

Los virus de inmunodeficiencia y leucemia felina representan un problema de gran envergadura para los felinos domésticos debido a la multiplicidad de sintomatologías que manifiestan. El objetivo del presente estudio fue establecer, retrospectivamente, la prevalencia en la presentación de ViLeF y VIF en pacientes de seis clínicas de pequeños animales en Bogotá y Chía, en relación con factores como su edad, raza y género. Se realizó un estudio transversal y retrospectivo, mediante la recopilación de datos de 1.014 historias clínicas de pacientes felinos que ingresaron a seis clínicas de la ciudad de Bogotá y Chía, para determinar la prevalencia de VIF y ViLeF y la asociación de estas con factores como edad, género y raza, entre 2015 y 2019, a través de la prueba OR. La detección de los virus se realizó mediante una prueba rápida basada en inmunocromatografía. La mayor prevalencia para cada enfermedad por año fue: 12,3% para VIF en 2012 y 18% para ViLeF en 2019. Los machos presentaron mayores seroprevalencias para ambas enfermedades durante la mayoría los años evaluados. Factores como raza (criolla: VIF: 1,85; ViLeF: 2,01), género (macho: VIF: 1,53 OR; ViLeF: 1,64) y edad (> 7 años: VIF: 3,82; ViLeF: 3,21) se relacionaron positivamente con la presentación de ambas enfermedades en la población felina evaluada.

Hemangiomas are benign tumors of vascular origin whose presentation in the breast is uncommon. They account for less than 1% of tumors of the breast, and therefore there are relatively few publications that describe their radiological characteristics. Hemangiomas in the breast are considered difficult to diagnose because their radiological characteristics are not specific, and it is very important to know their different forms of presentation. The purpose of this article is to share a case from Hospital San Jose de Monterrey with uncommon characteristics. [ABSTRACT FROM AUTHOR]

In a randomized study carried out in Cuba in laying hens and their replacements affected by the chronic respiratory syndrome (CRS), tracheas of 65 hens, 48 replacement and 30 without apparent clinical changes, were sampled. The samples were processed by conventional histology. As an unexpected finding the ossification of the hyaline cartilage of the trachea (OHCT) and the presence of bone marrow in the ossified nuclei were observed. This was confirmed by Giemsa staining where myeloblastics and erytroblastics cells could be identify. Taking into consideration the relationship between the respiratory failure and the OHCT with heterotopic hematopoiesis in both categories, the following hypothetical mechanisms can be established : birds could establish an adaptation from Hb to the chronic hypoxia to the hematopoiesis formation in the OHCT, as a compensatory mechanism against the chronic hypoxia caused by the respiratory failure, besides existing a close relationship between osteoblasts (OHCT) and the heterotopic hematopoiesis.

Etofenamate is a non-steroidal antiinflamatory drug (NSAID) with good analgesic and anti-inflammatory effectiveness, low toxicity, high bioavailability and few side effects that has been used for a long time in the treatment of pain produced by traumatic musculoskeletal conditions. This is an open, non-comparative study to test 1,0 g intramuscular etofenamate, single dose, in 139 patients, 91 (65%) female and 48 (35%) male sex, age range 40 to 49 years old. Types of acute pain included were: back pain, headache, joint pain, chest pain, neck pain, other muscle aches, earache, traumatic pain, pharyngitis and dysmenorrhea. Pain intensity was evaluated with the 0-10 points visual analogic points scale. At baseline, 58.3% of patients complained of severe pain; 30 min after etofenamate administration, 77% of patients reported the pain was moderate and 60 min after treatment, 74.1% described the pain as mild. Differences were statistically significant (p <0.05). One patient presented a delayed allergic reaction, 48 hours after etofenamate administration. [ABSTRACT FROM AUTHOR]

According to the methodology proposed by the FITOPLANT group of the Agrarian University of La Habana, an evaluation of the heavy metal content in liquid residuals of the system of traps and drainage of the company White Ceramic "Adalberto Vidal" in San José de Las Lajas, La Habana, Cuba was done, as well as its impact in the surrounding zone in the period of 2006-2008. Samples of liquid residuals were taken in different points of the trajectory, extending its representativeness during the three years of study. An analysis of the heavy metals: Cu, Co, Fe, Zn, Ni, Pb, Mn as well as Mg, Na, Ca, K, was performed by atomic spectrophotometry absorption. It was determined that high concentrations of metals existed (over the permissible limits), and they were toxic for the environment. The traps of this Company do not exert the function for which they have been designed and they seriously affect the area and the adjacent ecosystem. When the involved social actors (farmers, workers, and the company's Advisory Council) were questioned, they recognized many affectations in crops, animals and other components of the ecosystem that were consequence of the indiscriminate pouring of the referred industrial remainders. There was a strong community impact over the population surrounding the industrial plant that may affect their food security. A deep analysis of the liquid residuals of this company was recommended, and an appropriate environmental education program was established which approached the subject of the contamination by heavy metals and the ways to restore the damaged areas.

Objetivo: evaluar la detección de los defectos óseos con la radiografía periapical convencional (RPC), radiografía periapical digital directa (RPDD), radiografía panorámica digital (RPD) y tomografía Cone Beam (TCB) en mandíbulas humanas resecas. Métodos: se utilizaron 15 implantes Restore® y Renova® (Keyston Dental, Burlington, Estados Unidos) colocados en cinco mandíbulas humanas resecas. Luego se crearon defectos óseos perimplantares aleatoriamente: cinco sitios sin defectos óseos, cinco defectos óseos de 0,5 mm, cinco defectos óseos 1,5 mm, cinco defectos óseos de 2,0 mm y cinco defectos óseos de 3 mm. Se realizaron tomas radiográficas con: RPC, RPDD, RPD y TCB. Las imágenes radiográficas fueron leídas por un observador en tres momentos diferentes. El diagnóstico de la presencia o ausencia de defectos óseos perimplantares se registró en una escala de cinco puntos. Resultados: la RPDD presentó una sensibilidad (75 %) al igual que la RPC y, además, una mejor especificidad (100 %) en comparación con las otras técnicas radiográficas. Los niveles de concordancia intraobservador fueron moderados para RPDD, RPC y RPD. La TCB presentó una concordancia intraobservador discreta. La correlación entre la detección y el tamaño de los defectos fue positiva. Conclusión: la RPDD es el método más exacto en la detección de defectos óseos perimplantares seguida de la RPC, la RPD y la TCB. [ABSTRACT FROM AUTHOR]

Introducción: la spirulina máxima es una alga verdeazul utilizada para el consumo humano desde tiempos ancestrales. Recientemente ha producido un gran interés su estudio debido a la gran cantidad de componentes de la misma, entre los que destaca un alto contenido de proteínas, calcio, minerales, vitaminas, beta carotenos y otros nutrimentos como la ficocianina. Este es un pigmento que se encuentra en un 15% en la spirulina máxima, responsable de la protección contra los radicales libres con potencial benéfico para la salud. Por otro lado, la enfermedad de Parkinson (EP) se caracteriza por la degeneración de las neuronas dopaminérgicas, Iocalizadas en la sustancia negra pars compacta (SNc), causando disminución del neurotransmisor de dopamina (DA) en el cuerpo estriado (CE). La administración de la 1 -metil-4-fenil-1,2,3,6-tetrahidropiridina (MPTP) produce un estado parkinsónico en animales. El 1-metil-4-fenilpiridino (MPP+), es el metabolito tóxico estable de la MPTP productor de radicales libres que producen el daño neurotóxico. Por lo antes mencionado se utilizó la spirulina máxima para determinar el posible efecto neuroprotector en este modelo experimental de la enfermedad de Parkinson. Material y métodos: se utilizaron ratones C-57 black que fueron pretratados con spirulina máxima (25, 50, 100, 150, 200, 400 y 800 mg/kg) durante 14 días y después se les administró MPTP, (30 mg/kg i.p.), enseguida fueron tratados o travez con las mismas concentraciones de spirulina máxima durante ocho días más. Después se sacrificaron los animales y se determinó la concentración de DA en el CE por cromatografía de líquidos de alta resolución. Resultados: la dosis de 150 mg/kg de spirulina máxima protege de la disminución de DA en CE un 65 % contra la toxicidad producida por la MPTR Conclusión: estos resultados muestran que el p retrata miento con la spirulina máxima previene los efectos neurotóxicos de la MPTR sugiriendo su uso como una posible alternativa de terapia experimental.

The present study was carried out to evaluate the biostimulating effects of oral administration of cold-water Pleurotus spp. extract (F-I) prepared from fruiting bodies on the recovery of undernourished mice after a 5 days fasting. Signs of malnutrition appeared after the starvation period (group M). Female Balb/c mice, aged 8 weeks and weighing 18-20 g were used thoughout this study. Mice were refed ad libitum for 8 days with commercial pelleted diet (M-DC) or the commercial diet and the F-I extract administered orally at a dose of 100 mg/kg/ day (M-(F-I)). Normal-fed mice were used as controls. Leukocyte conts was studied. The levels of sera proteins and the hepatic and small intestine adaptation were considered. After a 8 day oral treatment with starved mice showed increased leukocyte counts in peripheral blood compared with M-DC group or the control mice. Positive results, in terms of sera proteins and hepatic and small intestine adaptation have been obtained in the group recovered with F-I in addition to diet. The biostimulating properties of this edible mushroom extract are certain to lead to application as a physiologically functional food in the field of pharmacological nutrition. [ABSTRACT FROM AUTHOR]
