Interacciones de las radiaciones electromagnéticas y especies reactivas del oxígeno sobre la piel/ Interactions of electromagnetic radiations and reactive oxygen species on skin

Ferramola de Sancovich, A M; Sancovich, H A
2006-06-01

Resumen en español La energía radiante abarca todo el espectro electromagnético y proviene de la fusión en el sol, de 4 núcleos de hidrógeno en uno de helio. Las radiaciones electromagnéticas tienen características de ondas, con la velocidad de la luz (c) y difieren en sus longitudes de ondas (λ). La energía lumínica es transmitida en unidades individuales o fotones: E = h c/λ así, los fotones de menores λs son los de mayor energía. Las radiaciones ultravioletas (U (mas) V) (λs de 200 - 400 nm) pueden dividirse: UVA (λs 315 - 400 nm); UVB (λs 280 - 315 nm) y UVC (λs Resumen en inglés The energy of electromagnetic radiation is derived from the fusion in the sun of four hydrogen nuclei to form a helium nucleus. The sun radiates energy representing the entire electromagnetic spectrum. Light is a form of electromagnetic radiation. All electromagnetic radiation has wave characteristics and travels at the same speed (c: speed of light). But radiations differ in wavelength (λ). Light energy is transmitted not in a continuum stream but only in individual (mas) units or photons: E = h c/λ. Short wave light is more energetic than photons of light of longer wavelength. Ultraviolet radiations (UV) (λs 200 - 400 nm) can be classified in UVA (λs 315 - 400 nm.); UVB (λs 280 - 315 nm) and UVC (λs

Formación de pelos en el alga agarófita gracilaria chilensis(Gracilariales, Rhodophyta)/ Hair formation in the agarophyte alga Gracilaria chilensis (Gracilariales, Rhodophyta)

Garcia, Maximiliano D.; Miravalles, Alicia B.; Leonardi, Patricia I.
2007-07-01

Resumen en español Gracilaria chilensis es un alga roja agarófita perteneciente a la clase Florideophyceae. En este estudio se describe la formación de pelos en talos mantenidos en cultivo en agua de mar enriquecida, bajo condiciones controladas de luz y temperatura. La inducción de los pelos fue realizada colocando porciones de talos en un medio de cultivo carente de compuestos nitrogenados. Se emplearon técnicas de microscopía óptica y electrónica de transmisión y barrido. Los pel (mas) os se desarrollan a partir de células corticales ovoides grandes. Estas células formadoras de pelos (CFPs) son multinucleadas, poseen pequeños plástidos y una abundante red de retículo endoplasmático de disposición apical. La formación de los pelos comienza con el desarrollo de una protuberancia, inicialmente cubierta por una pared multilaminar, la cual se rompe junto con la pared del talo, con la consecuente elongación de la protuberancia. El pelo queda establecido cuando se produce una citocinesis en la base de la protuberancia, formándose una conexión citoplasmática obliterada o "pit plug" asimétrica entre la base del pelo y la CFP. Los pelos son unicelulares, poseen una vacuola y numerosos núcleos. Tienen un crecimiento activo dejando, al caerse, una cicatriz de forma concéntrica en la pared. Se compara este proceso con el descrito en otras especies de la clase. En medios de cultivo carentes de nitrógeno, el crecimiento del talo de G. chilensis fue menor, aumentando el número de pelos. Resumen en inglés Gracilaria chilensis (Gracilariales) is an agarophyte red alga belonging to class Florideophyceae. The purpose of this study was to describe the hair formation mechanism. Thalli were maintained in culture with enriched seawater under controlled conditions of light and temperature. Hair formation was induced on portions of thalli growing in a nitrogen-free culture medium. Light (bright field) microscopy, transmission and scanning electron microscopy techniques were used. H (mas) airs develop from large ovoid hair-producing cortical cells (HPCs). These cells are multinucleate, contain small plastids, and abundant endoplasmic reticulum apically positioned. Each hair begins as a protuberance initially covered by a multilaminar wall, this is, in turn, ruptured along with the thallus wall as the protuberance elongates. Hairs are formed when cytokinesis occurs at the base of the protuberance. An asymmetric pit plug is formed between the hair's base and the HPC. Hairs are unicellular, with a vacuole and numerous nuclei. They have an active growth, and leave a concentric scar on the wall after detachment. Hair formation mechanism in G. chilensis is also compared with that observed in other species of the same class. In nitrogen-free culture media, the thallus of G. chilensis grows less, but the number of hairs increases.

Resumen en español Se desarrolló la caracterización de suspensiones de recubrimiento de núcleos placebos en sistemas acuosos que tenían como base polycoat 2 blanco, las que fueron coloreadas con 3 colorantes Lake diferentes. Se evaluó la densidad de estas suspensiones con diferentes porcentajes de sólidos dispersos (10-20 %), y se observó un aumento de estas con el incremento de sólidos dispersos. Se realizó el recubrimiento de núcleos placebos de diferentes tamaños de troquel y (mas) a las tabletas recubiertas se les efectuó un estudio de estabilidad del color a la luz, mediante la evaluación de su densidad óptica, estableciéndose el orden amarillo > azul > rojo. Se llevó a cabo un estudio de ganancia de humedad de las tabletas recubiertas a diferentes humedades relativas en hidrostatos estabilizados, y se confirmó la eficacia del sistema de recubrimiento para la protección de las tabletas en condiciones normales de humedad relativa. Los parámetros físico-químicos evaluados en núcleos placebos y tabletas recubiertas cumplen con los límites establecidos y se discuten algunos de ellos. Resumen en inglés The characterization of suspensions for coating placebo nuclei was developed in aqueous systems with white polycoat 2 as a base. The suspensions were colored with 3 different Lake coloring matters. The density of these suspensions was evaluated with diverse percentages of disperse solids (10-20 %). An increase of them was observed with the increment of disperse solids. The coating of placebo nuclei of different die sizes was carried out and the coated tablets were submitt (mas) ed to a study on the stability of color to light by evaluating their optical density. The following order was established: yellow > blue > red. A study on the humidity gain of the coated tablets was conducted at various relative humidities in stabilized hydrostats and the efficiency of the coating system for protecting tablets under normal conditions of relative humidity was confirmed. The physical and chemical parameters evaluated in placebo nuclei and coated tablets fulfilled the established limits and some of them were discussed.

Adenoma silente subtipo 3: importancia del estudio ultraestructural en el diagnóstico diferencial del adenoma hipofisiario asociado a hiperprolactinemia en un caso/ Silent pituitary adenoma type 3 associated to hyperprolactinemia.: Report of one case

Quevedo L, Iván; Rodríguez P, José A; Gejman E, Roger; Méndez S, Jorge
2001-03-01

Resumen en inglés The association of hyperprolactinemia over 100 ng/ml and a pituitary adenoma is usually diagnostic of prolactinoma. However type 3 pituitary adenomas can occur with similar serum prolactin values. We report a 31 years old woman that consulted due to headache and photopsiae. She had a serum prolactin level of 148 ng/ml and imaging studies showed a solid tumor that occupied the selar region and most of the left temporal fossa. The tumor was partially resected and the patien (mas) t recovered her lost visual field. Light microscopy showed an acidophilic and in part chromophobe adenoma. Immuno-histochemistry was positive for prolactin and growth hormone. Electron microscopy disclosed features of a silent type 3 adenoma such as big cells with cytoplasmic prolongations, pleomorphic nuclei and a greatly developed rough endoplasmic reticulum.
