The present knowledge of the marine phanerogams of the Canary Islands is poorly documented. Earlier studies of the marine phytobenthos along the Canarian coasts provide little information on seagrass ecosystems and their distributional patterns. This contribution summarizes the available information about the three species reported for the islands: Cymodocea nodosa (Ucria) Ascherson, Halophila decipiens Ostenfeld and Zostera noltii Hornemann; and their distributional records is analized in relation ...

Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS) was applied to the quantitative analysis of magnesium carbonate content in papers treated with non-aqueous deacidifying solution. The method proved to be reasonably accurate for papers which are susceptible to impregnation, so that carbonate deposits are evenly distributed throughout the paper (or its surface, where the actual measurement takes place). The curve-fitting was performed by classical leastsquares technique, using several ...

During research to assess the effectiveness of the mass deacidification treatment developed at the Universitat Politècnica de Catalunya (UPC-ETSIIT-Spain), the changes produced in several chemical and physical properties of papers dating from the 17th, 18th and 19th centuries were compared, particularly the changes in viscosimetric degree of polymerization and colour parameters (lightness, chroma, and hue) caused by ageing and deacidification. A good statistical correlation between the colour differences ...

Oxidesulfurization (ODS) of benzothiophenic compounds prevailing in diesel was conducted with hydrogen peroxide in presence of various catalysts, using a model diesel and actual diesel fuel. ODS activities of dibenzothiophenes (DBTs) in hexadecane for a series of V2O5 catalysts supported on alumina, titania, ceria, niobia and silica, were evaluated. Results show that the oxidation activity of DBTs depends on the support used. It was observed that the sulfone yield is not proportional to textural properties ...

Abstract: Juvenile sulfatidosis (Austin type) or multiple suifatase deficiency is an extremely rare autosomai recessive disorder affecting the activity of many suifatases: arylsuifatase A, several mucopolysaccharide sutfatases, and steroid sulfatase. Certain aspects of the ciinical phenotype can be attributed mainly to a deficiency of one specific suifatase. Most patients develop metachromatic ieukodystrophy caused by aryisuifatase A deficiency, dysostosis multiplex by mucopolysaccharide sulfatase ...

This year, a respiratory virus caused an emergency pandemic alert in health services around the world, showing the need for biotechnological approaches to fight these diseases. The influenza virus is one of the main viral agents that generate pandemic outbreaks. Currently, the majority of co-circulating influenza A virus (IAV) strains are adamantine‐ and oseltamivir-resistant strains, and the challenge is to find new antivirals for more efficient treatments. The antiviral entry blocker (EB) peptide ...

In this article the closed-loop stability conditions and the control design of a class of biological system that exhibit chaotic oscillations are addressed. It is proved that the biological system is minimum phase. A class of nonlinear dynamic feedback control is designed using sliding-mode control ideas, which can be used for regulation, tracking and synchronization tasks. Numerical experiments illustrate the satisfactory performance of the proposed control methodology.

Varroa destructor has been in Brazil for more than 30 years, but no mortality of honeybee colonies due to this mite has been recorded. Africanized bee infestation rates attained by varroa have been low, without causing measurable damage to Brazilian apiculture. The low reproductive ability of this parasite in Africanized bee worker brood cells has been considered an important factor for maintaining the host-parasite equilibrium. Nevertheless, the possible substitution of the haplotype of the mite ...

However, factors such as buffer type and amount added do not take into account the intrinsic buffering capacity of other dietary ingredients. Objective: to determine the buffering capacity (BC) of 25 commonly used energy and protein feedstuffs as well as additives, silages, and forage ingredients. Methods: BC was measured using the technique described by Jasaitis et al. (1988). Results are expressed in milliequivalents of ...

Genital human Papillomavirus infection is common and only a minor fraction of infected subjects develop progressing cervical epithelial lesions or cancer. Bypassing local immune responses is important for the development of cervical cancer. In this work we determined the cytokine pattern in samples from patients with cervical cancer. Thus, we examined the local mRNA expression profile of helper T cell type 1 (Th1), Th2, and Th3 cytokines in HPV-positive cervical cancer biopsies by reverse transcription- ...

Gpn3 is required for RNA polymerase II ( RNAPII ) nuclear targeting. Here, we investigated the effect of a cancer‐associated Q279* nonsense mutation in Gpn3 cellular function. Employing RNA i, we replaced endogenous Gpn3 by wt or Q279* RNA i‐resistant Gpn3R in epithelial model cells. RNAPII nuclear accumulation and transcriptional activity were markedly decreased in cells expressing only Gpn3R Q279*. Wild‐type Gpn3R localized to the cytoplasm but a fraction of Gpn3R Q279* entered the cell nucleus and ...

Breast cancer is the most common type of cancer affecting women worldwide and its risk increases with age. Compared with other breast cancer subtypes, triple negative breast cancer (TNBC) behaves more aggressively, with earlier relapses and poorer survival outcomes.
