El objetivo del presente estudio ha sido evaluar la relación entre los parámetros de la calidad seminal y la capacidad de penetración in vitro de ovocitos homólogos (PIVh) con los resultados in vivo de fertilidad y prolificidad.
Se han analizado 60 eyaculados realizando sobre cada uno las mediciones
clásicas del espermiograma (motilidad, calidad de movimiento, volumen, concentración espermática, estado del acrosoma, morfoanomalías y tinción vital), pruebas bioquímicas (contenido de ATP, calcio, sodio, potasio, magnesio y zinc), ensayos de la funcionalidad del espermatozoide ( test de endósmosis, test del diacetato de carboxifluoresceína, test ORT) y la valoración mediante un test de penetración in vitro homóloga. Los resultados de la valoración in vitro del semen fueron contrastados con los resultados obtenidos en un ensayo in vivo...
This article analyses Miguel de Unamuno’s response
to the Great War of 1914-1918 and the influence
that the War had on Unamuno’s work and
role as an intellectual. It deals with the following
themes: the origins and nature of Unamuno’s support
for the Allies during the War; the role that the
War played in Unamuno’s evolution as an intellectual
and political figure; Unamuno’s reading
of the political situation in Spain over these years;
and his understanding of the lasting effects and
consequences of the War in Spain and in Europe
as a whole.

Animal models of human EBV-associated
diseases are essential to elucidate the pathogenesis of
EBV-associated diseases. Here we review those previous
models using EBV or EBV-like herpesviruses and
describe the details on our two newly-developed rabbit
models of lymphoproliferative diseases (LPD) induced
by simian EBV-like viruses. The first is Cynomolgus-
EBV-induced T-cell lymphomas in rabbits inoculated
intravenously (77- 90%) and orally (82- 89%) during 2 -
5 months. EBV-DNA was detected in peripheral blood
by PCR from 2 days after oral inoculation, while anti-
EBV-VCA IgG was raised 3 weeks later. Rabbit
lymphomas and their cell lines contained EBV-DNA and
expressed EBV-encoded RNA-1 (EBER-1). Rabbit
lymphoma cell lines, most of which have specific
chromosomal abnormality, showed tumorigenicity in
nude mice. The seco...
The present study reported histochemical
changes in alveolar bone glycosaminoglycans (GAG)
(using Safranin 0 ) and in interdental bone height in
three groups of BB/W rats: diabetic, diabetes prone, and
diabetes resistant. Safranin O staining intensity
suggested that total GAG levels were highest in diabetic
bone (p<0.05 compared to diabetes resistant, p<0.005
compared to diabetes prone) but not significantly
different between diabetes prone and resistant groups.
Following chondroitinase AC and ABC digestion,
staining reactions suggested that the highest levels of
dermatan sulfate were in the diabetes resistant group
(p<0.001 compared to diabetic, p<0.001 compared to
diabetes prone) and the highest levels of chondroitin
sulfates were in the diabetes prone group (p<0.001).
Coincidently the mean height of diabetes prone
in...
Substance P-immunoreactive (SP-I) structures
in the carotid bodies of rats and cats were examined with
the light and electron microscopes. In both species SP-I
varicose nerve fibers were located singly in the interstitial
connective tissue in close association with blood vessels.
They were small unmyelinated fibers enveloped in a
common Schwann cell sheath with other SP-negative fibers.
Some of SP-I fibers contained large dense-cored granules
and small clear vesicles in addition to microtubules and
mitochondria and probably represented nerve fiber
varicosities. The latter often were found incompletely
invested by Schwann cell sheaths. SP-fibers were found
occasionally in the envelopes of supporting cells at the
periphery of parenchymal cell groups. However, none of
the nerve terminals making synaptic contacts with glomus ...
