CANDIDA SEPTIC THROMBOSIS OF THE LEFT ATRIUM IN TWINS: REPORT OF TWO CASES
2009
Background: Preterms are often exposed to nosocomial infections in NICU. Candida infections are particularly common and can result in progressive organization of intracardiac thrombosis, usually in the right atrium. Design and population: GB (24.4 wg, 460 g, bigeminal pregnancy): he was affected by RDS, PDA, jaundice, anaemia and had been submitted to TPN with CVC, also because of anus imperforate. On the 50th day, haemoculture resulted positive for Candida parapsilosis and, by echocardiography, hyperecogen peduncolate formation in the appendix of left auricola. Despite antifungal therapy, exitus occurred. CM (32.4 wg, 1390 g, bigeminal pregnancy): on 2nd day, she was operated for “apple-pe…
A petrol ether extract of the roots of Onosma paniculatum induces cell death in a caspase dependent manner
2010
Traditional Chinese medicine (TCM) has become very popular in Western countries during the last years. Zicao, a remedy of TCM, has been traditionally used to treat cancer, and, its main constituents, naphthoquinones, have been reported to possess antitumor activity (Chen et al., 2002; Papageorgiou et al., 1999). Here, we prepared extracts of different polarities of Onosma paniculatum Bur.Franch., a plant which is amongst others used as Zicao, but, much less investigated. The extracts were analyzed concerning their growth inhibitory and apoptosis-inducing activity in various tumor cells.Cell viability was measured by XTT viability and a growth inhibition assay. Effects on the cell cycle and …
Novel avidin-like protein from a root nodule symbiotic bacterium, Bradyrhizobium japonicum.
2005
Bradyrhizobium japonicum is an important nitrogenfixing symbiotic bacterium, which can form root nodules on soybeans. These bacteria have a gene encoding a putative avidin- and streptavidin-like protein, which bears an amino acid sequence identity of only about 30% over the core regions with both of them. We produced this protein in Escherichia coli both as the full-length wild type and as a C-terminally truncated core form and showed that it is indeed a high affinity biotin-binding protein that resembles (strept)avidin structurally and functionally. Because of the considerable dissimilarity in the amino acid sequence, however, it is immunologically very different, and polyclonal rabbit and…
Computational fluid dynamics of the ascending aorta before the onset of type A aortic dissection.
2016
We performed a pre-dissection computational fluid analysis of an ascending aortic aneurysm associated with unicuspid aortic valve. The analysis showed an abnormal helical flow pattern inside the aneurysm and an increased wall stress on the right postero-lateral wall of the ascending aorta. These values were largely higher than the theoretical cut-off for aortic wall dissection, their topographic distribution followed the intimal tear site as subsequently diagnosed by computed tomography scan and confirmed during the operation for dissection repair.
Analyse comparée des critères de la première molaire inférieure entre différentes populations du campagnol basque Microtus (Terricola) lusitanicus (G…
2009
9 pages; National audience; L'objectif de cette étude est l'analyse comparée des critères de la première molaire inférieure (M1) entre sept groupes géographiques du campagnol basque Microtus (Terricola) lusitanicus (Gerbe, 1879) répartis sur l'ensemble de l'aire de répartition de l'espèce. Le principal résultat est la différenciation du groupe des Pyrénées françaises, caractérisé en particulier par un développement réduit de la partie antérieure de la M1. Dans les groupes géographiques ibériques, des différences morphologiques sont trouvées pour chaque critère, mais ces différences sont moins significatives que celles observées pour le groupe des Pyrénées françaises. Le statut sub-spécifiqu…
The Brain’s Camera. Optimal Algorithms for Wiring the Eye to the Brain Shape How We See
2016
The problem of sending information at long distances, without significant attenuation and at a low cost, is common to both artificial and natural environments. In the brain, a widespread strategy to solve the cost-efficiency trade off in long distance communication is the presence of convergent pathways, or bottlenecks. In the visual system, for example, to preserve resolution, information is acquired by a first layer with a large number of neurons (the photoreceptors in the retina) and then compressed into a much smaller number of units in the output layer (the retinal ganglion cells), to send that information to the brain at the lowest possible metabolic cost. Recently, we found experimen…
Seeing with the visual cortex
1984
A short analysis of the input-output organization of the primary visual cortical areas in the cat and monkey is followed by a description of the salient microelectrophysiological properties of retino-geniculo-cortical system neurons. It is concluded that a strict hierarchical model of cortical processing of visual information is no longer tenable.
Root-induced decomposer growth and plant N uptake are not positively associated among a set of grassland plants
2007
Abstract It is known that plant species can induce development of different soil decomposer communities and that they differ in their influence on organic matter decomposition and N mineralization in soil. However, no study has so far assessed whether these two observations are related to each other. Based on the hypothesis that root-induced growth of soil decomposers leads to accelerated decomposition of SOM and increased plant N availability in soil, we predicted that (1) among a set of grassland plants the abundance of soil decomposers in the plant rhizosphere is positively associated with plant N uptake from soil organic matter. To test this, we established grassland microcosms consisti…
Ecological Analysis of the Helminth Community of Microtus lusitanicus (Gerbe, 1879) (Rodentia) in Asturias (NW Spain)
2021
Simple Summary The Lusitanian pine vole is an endemic rodent of the Iberian Peninsula, which has a burrowing behaviour and prefers to live underground. It feeds on bark and roots causing severe damage to trees. In Asturias (NW Spain), this species is considered a pest causing economic losses in apple orchards, damaging the tree, and sometimes even causing its death. With the aim to shed light on the helminth community of this rodent pest species and to elucidate which intrinsic and extrinsic factors affect its helminth species, a faunistic-ecological study was carried out. For this purpose, our own collection of 710 voles from several orchards of various locations in Asturias was used. The …
