Delayed filling of retinal and ciliary circulation after central retinal artery occlusion

1988

The filling times of the retinal and choroidal circulation were evaluated in 17 patients with central retinal artery occlusion by means of fluorescein angiography. A correlation between the filling times of the two circulations was found. However, two filling patterns were seen: first, both fillings delayed; second, both fillings normal. It is probable that in the former case an obstructive disease of the carotid arteries exists, while in the latter case an important pathology of the carotid arteries is lacking, favouring a rapid restoration of the retinal circulation. This hypothesis seems to be confirmed by the results of the Doppler velocimetry of the carotid arteries.

El Guadalaviar y la configuración de Valencia : su interpretación a partir de las vistas urbanas modernas

2004

Pablo.Cisneros@uv.es Valencia responde a una configuración urbana creada por del río Turia o Guadalaviar. Esta relación es apreciable, claramente, en las numerosas imágenes urbanas que de esta ciudad se han conservado. Así, en el presente artículo se pretende realizar un estudio del río y de la ciudad a partir de las imágenes de Valencia en la Edad moderna. The Guadalaviar and configuration of Valencia. Its interpretation from the modern urban views. Valencia replies to an urban shape created by the Turia river or Guadalaviar. This relation is appreciable, clearly, in the numerous urban images which have been conserved in this city. Thus, in the present article pretends to carry out a study…

CADASTRAL MODELS IN EU MEMBER STATES

2019

Abstract Cadastres are always related to land: they are a creation of man as effect of his relationship with land. The different conditions of the Cadastre in 14 EU Member States, including the former EU Candidate States (that nowadays are also EU members), are shown in this paper. Half of EU countries store cadastral and registration data in the same database. Basically two original models of cadastral system exist in the EU, related with systems of land registration : 1) in the Central European model (beyond the area of the Germanic “Grundbuch”) Cadastre emerges as a graphic basis (map) of land registration (Land Registry), so that physical changes must be reflected in the Cadastre and le…

Catheters in Regional Anesthesia

2014

Anesthesiologists use different types of catheters in the performance of continuous regional anesthetic techniques such as epidural, subarachnoid, and paravertebral blocks, as well as peripheral nerve blocks.

Termination of transcription in an ‘in vitro’ system is dependent on a polyadenylation sequence

1991

Using HeLa cell nuclear extract as a source of the different transcription and polyadenylation factors and reverse transcription to analyze the levels of RNA 5' and 3' to the cleavage-polyadenylation site, an in vitro assay has been established to study polyadenylation coupled to transcription directed by different adenovirus promoters. The levels of transcription 5' and 3' to the cleavage site in the L3 polyadenylation region are practically the same as described previously, however, the level of transcription 3' to the cleavage site in the SV40 early polyadenylation region decreases immediately after the cleavage site indicating a termination of the transcription.

Nuclear receptors modulate the interaction of Sp1 and GC-rich DNA via ternary complex formation

2000

Binding sites for transcription factor Sp1have been implicated in the transcriptional regulation of several genes by hormones or vitamins, and here we show that a GC-rich element contributes to the retinoic acid response of the interleukin 1β promoter. To explain such observations, it has been proposed that nuclear receptors can interact with Sp1 bound to GC-rich DNA. However, evidence supporting this model has remained indirect. So far, nuclear receptors have not been detected in a complex with Sp1 and GC-rich DNA, and the expected ternary complexes in non-denaturing gels were not seen. In search for these missing links we found that nuclear receptors [retinoic acid receptor (RAR), thyroid…

Chromatin Domains and Regulation of Transcription

2007

Compartmentalization and compaction of DNA in the nucleus is the characteristic feature of eukaryotic cells. A fully extended DNA molecule has to be compacted 100,000 times to fit within the nucleus. At the same time it is critical that various DNA regions remain accessible for interaction with regulatory factors and transcription/replication factories. This puzzle is solved at the level of DNA packaging in chromatin that occurs in several steps: rolling of DNA onto nucleosomes, compaction of nucleosome fiber with formation of the so-called 30 nm fiber, and folding of the latter into the giant (50-200 kbp) loops, fixed onto the protein skeleton, the nuclear matrix. The general assumption is…
