Abstract A characterization of the bacterial community of the hindgut wall of two larval and the adult stages of the forest cockchafer (Melolontha hippocastani) was carried out using amplicon sequencing of the 16S rRNA gene fragment. It was found that, in second-instar larvae, Caulobacteraceae and Pseudomonaceae showed the highest relative abundances, while in third-instar larvae, the dominant families were Porphyromonadaceae and Bacteroidales-related. In adults, an increase of the relative abundance of Bacteroidetes, Proteobacteria (γ- and δ- classes) and the family Enterococcaceae (Firmicutes) was observed. This suggests that the composition of the hindgut wall community may depend on the…
Ultrasonographic Measurements of the Achilles Tendon in Elderly Athletes and Sedentary Men
1994
Ultrasonography was performed on the Achilles tendon of the dominant limb of 18 male elderly athletes and 11 sedentary men, aged 70 to 80 years. The tendons were examined with a real-time linear array scanner using a 7.5 MHz transducer. Both longitudinal and transverse images were taken. The mean width of the Achilles tendon was significantly larger in the athletes than in the control subjects. The tendon thickness and cross-sectional area did not differ significantly between the groups, but the figures may indicate a tendency for larger cross-sectional area in the athletes. The results suggest tendon hypertrophy following long-term training.
A Tool to Assess Architectural Education from the Sustainable Development Perspective and the Students' Viewpoint
2021
[EN] Architectural education plays a fundamental role in achieving sustainable development by training future professionals who can contribute to sustainability through their practice. Nevertheless, to ensure the introduction of sustainable development in the education of future architects, it is fundamental to understand what is being done and what could be improved. Despite this, a big gap has been detected in the assessment of architectural education in Spain and worldwide. Thus, a close-ended questionnaire for students has been designed based on the outcomes from a literature review, exploratory interviews with specialists, and the qualitative analysis of two schools of architecture. Ad…
Field and microcosm experiments to evaluate the effects of agricultural Cu treatment on the density and genetic structure of microbial communities in…
2006
The effects of Cu amendment on indigenous soil microorganisms were investigated in two soils, a calcareous silty clay (Ep) and a sandy soil (Au), by means of a 1-year field experiment and a two-month microcosm incubation. Cu was added as 'Bordeaux mixture' [CuSO(4), Ca(OH)(2)] at the standard rate used in viticulture (B1=16 kg Cu kg(-1) soil) and at a higher level of contamination (B3=48 kg Cu ha(-1) soil). More extractable Cu was observed in sandy soil (Au) than in silty soil (Ep). Furthermore, total Cu and Cu-EDTA declined with time in Au soil, whereas they remained stable in Ep soil. Quantitative modifications of the microflora were assessed by C-biomass measurements and qualitative modi…
“El Registro Civil y el contenido de su publicidad: experiencias españolas para el contexto cubano”
2021
La función de publicidad que caracteriza al Registro Civil lo convierte en una institución fundamental dentro del sistema de seguridad jurídica preventiva. De ahí que, sea importante estudiar si existe correspondencia entre el contenido de la publicidad del Registro y las situaciones jurídicas y sociales en que usualmente se desenvuelven las personas, como un medio para garantizar, desde esta perspectiva, su cuidado y desarrollo. En este sentido, se valora el contenido de la publicidad del Registro del Estado Civil cubano (Ley No.51/1985, de 15 de julio del Registro del Estado Civil), a partir de las experiencias españolas en la materia, siguiendo, en general, los avances de este último sis…
El consentimiento informado de los menores de edad en el ámbito sanitario
2021
: El consentimiento informado aparece como un derecho de todo paciente a decidir en el ámbito sanitario. En este marco, es necesario determinar si los menores de edad han de ejercitar este derecho o si, por el contrario, precisan de la intervención de un tercero para llevarlo a cabo. A este respecto, nuestra legislación actual reconoce, con carácter general, el derecho a decidir de este colectivo. No obstante, en ocasiones pueden producirse limitaciones a su ejercicio motivadas bien por la ausencia de capacidad real, bien por el principio de interés superior. En definitiva, se trata de alcanzar el mayor beneficio para los menores de edad en el campo de la salud, evitando que se produzcan pe…
Generación de centros estereogénicos cuaternarios heterosustiruidos mediante las reacciones de Henry y aza-Henry
2015
La adición de nitroalcanos a compuestos carbonílicos o sus derivados nitrogenados (reacciones de Henry y aza-Henry, respectivamente) constituye una herramienta fundamental para la formación de enlaces C-C en química orgánica.[1] Los productos resultantes de estas reacciones son "building blocks" muy interesantes en síntesis orgánica ya que permiten el acceso a diferentes motivos estructurales gracias a la versatilidad química del grupo nitro [2] siendo de gran utilidad para la síntesis de fármacos y productos agroquímicos.[3] Además, en el transcurso de estas reacciones pueden formarse uno o más centros estereogénicos por lo que el control de la estereoquímica resulta crucial. Por este moti…

Significance of passively induced stretch reflexes on achilles tendon force enhancement
1998
An in vivo buckle transducer technique was applied to study the reflex contribution to ATF enhancement during passive dorsiflexion stretches. Single stretches led to a linear ATF increase in the absence of an EMG reflex response, whereas clear ATF enhancement over the passive component occurred 13-15 ms after the onset of EMG responses. To quantify the reflexly induced increase in ATF, the stretched position was maintained. The mean reflex effect was two to four times greater than the passive stretch effect.
Abnormal pentagastrin response in a patient with pseudohypoparathyroidism
2002
The case of a 25 year old female patient with pseudohypoparathyroidism type I (PHP) and hypercalcitoninaemia is reported. She was referred to our clinic because of recurrent hypocalcaemia associated with paraesthesias and muscle cramps. She had no signs of Albright hereditary osteodystrophy (AHO), a normal mental status and no family history of hypocalcaemia or any other endocrine disease. Considering the laboratory results with hypocalcaemia, hyperphosphataemia, normal vitamin D and normal creatinine with an extraordinary elevated PTH we diagnosed pseudohypoparathyroidism type I. She had delayed pubertal development with menarche in the age of 20 and hypothyroidism with an atrophic thyroid…
