Variación anual del polen en la atmósfera de Ponferrada: Años 1995-96

Variación anual del polen en la atmósfera de Ponferrrada. Años 1995-96. El objeto de este estudio es conocer la concentración de polen y la periodicidad anual del mismo, en la atmósfera de la ciudad de Ponferrada (León). El muestreo aerobiológico se ha realizado durante dos años consecutivos (1995-96), mediante un captador volumétrico tipo Hirst (modelo Lanzoni VPSS-2000), situado a unos 10 m del suelo. Durante este periodo se han identificado 66 tipos polínicos de ellos, 22 (96%) constituyen el espectro polínico principal, de esta estación de muestreo. Entre Enero y Julio, se produce la máxima emisión de polen al aire, y desde Septiembre a Diciembre la cantidad de polen atmósferico es muy escasa. Los tipos polínicos predominantes cuantitativamente han sido: Cupressaceae (21,3%), Poaceae (19,2%), Pinaceae (12,6%), Quercus (10%), Castanea sativa (6,2%), y Betula (3,6%), que junto con Alnus, Erica, Plantago, Populus, Rumex y Urticaceae, suponen el 91,9% del polen total de la atmósfera de Ponferrada. Se ha detectado un predominio anual de pólenes de especies leñosas frente a herbáceas. Desde el punto de vista clínico, los pólenes de Poaceae (60%) son, con mucho, los que ocasionan mayor patología polínica, seguidos de Plantago (27%) y Betula (12%)

When invasion biology meets taxonomy: Clavelina oblonga (Ascidiacea) is an old invader in the Mediterranean Sea

Taxonomic issues often confound the study of invasive species, which sometimes are unrecognized as introduced in newly colonized areas. Clavelina oblonga Herdman, 1880 is an abundant ascidian species along the southeastern coast of the United States and the Caribbean Sea. It was introduced into the eastern Atlantic and Brazil decades ago. In the Mediterranean Sea, a similar species had been described as C. phlegraea Salfi 1929 and reported from southern Italy and Corsica. In the last few years a species of Clavelina has proliferated in the embayments of the Ebro Delta (NW Mediterranean), a zone of active bivalve culture industry where it has smothered mussel spat, leading to economic loss. We here report the morphological and genetic identity of this species, synonymizing the Atlantic C. oblonga and the Mediterranean C. phlegraea (the latter therefore is a synonym of the former). Thus, C. oblonga has existed in the Mediterranean for over 80 years, but was known under a different name. We also found this species in natural habitats in the Iberian Atlantic coast close to the Strait of Gibraltar, raising concerns about an ongoing expansion. In order to obtain information relevant for management, we monitored growth, reproductive cycles and settlement patterns of this ascidian on bivalve cultures in the Ebro Delta. Its biological cycles were markedly seasonal, with peak abundance and reproduction during the warmest months, followed by regression during the cold season. The settlement period was short, mostly concentrated in a single month each year. Avoidance of mussel and oyster seeding during late summer and early autumn can readily reduce the damage caused by this species

Seasonal patterns of settlement and growth of introduced and native ascidians in bivalve cultures in the Ebro Delta (NE Iberian Peninsula)

Ascidians are important both as invasive species and as a fouling group in artificial marine habitats, causing negative impacts in aquaculture settings and the surrounding environment. The Ebro Delta is one of the major centres of bivalve production in the Mediterranean and is affected by proliferation of ascidian species (mostly introduced forms). Knowledge of the patterns of settlement and growth of the fouling species is mandatory to attempt mitigation measures. Settlement PVC plates were deployed from May to September 2015 at different depths (0.2, 1 and 2 m) in the Ebro Delta oyster aquaculture facilities. The occurrences of all species and the area cover of a selected subset of 6 species were monitored on a monthly basis from June 2015 to December 2016. Fifteen species were found, of which 10 are introduced. There were some differences between the deployed plates and the oyster ropes in species abundance and composition, likely due to differences in substrate complexity. For instance, Didemnum vexillum and Clavelina oblonga occurred in few plates in contrast to their abundance on oysters. The most abundant species were Styela plicata and Clavelina lepadiformis, which together with Ecteinascidia turbinata showed a preference to grow on plates deployed in May and June. Most of the species grew more at 0.2 m depth than at deeper plates. Thus, to minimise fouling on bivalves, spat immersion during fall and below 1 m depth is recommended. The number of occurrences and cover of the species was found to be similarly informative; suggesting that a periodic monitoring of species occurrence on replicate plates is sufficient for detecting new introduced species as soon as possible and will provide information useful for management

Cost-effectiveness of upper extremity dry needling in the rehabilitation of patients with stroke

Introduction: Dry needling (DN) has been shown to be effective for the treatment of upper extremity hypertonia in patients with stroke. Purpose: To evaluate the cost-effectiveness of DN in patients with stroke. Methods: A cost-effectiveness analysis was performed in a research study conducted at a Spanish public hospital where patients were classified into two groups with or without DN. Hypertonia was measured using the Modified Modified Ashworth Scale (MMAS), and quality of life (QOL) was assessed using the EuroQoL 5-dimension questionnaire. Data regarding the effects and costs of physiotherapy were presented by calculating the mean and 95% confidence interval. The health outcomes were evaluated considering the rate of responders to the treatment based on the MMAS. Spanish preference weights were used to estimate quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) and incremental cost-utility ratio (ICUR) were calculated to determine the economic value of DN. Results: Eighty patients with stroke in the subacute stage of recovery were selected to participate in this study. Based on the rate of responders, the ICER of the DN group was very low. Despite the sensitivity analysis performed, the results of the ICUR were not encouraging. Discussion: Cost-effectiveness with responder rate results were favourable for the DN group and were confirmed by the sensitivity analysis according to levels of care. In addition, our findings revealed that 4 weeks of treatment could be more cost-effective than 8 weeks. DN treatment of the upper extremity appears to be cost-effective based on the rate of responders measured using the MMAS scale. © The Author(s) 2021

Osteopoiquilia: A propósito de 2 casos

La osteopoiquilosis es una rara displasia ósea esclerosante. Su diagnóstico es normalmente hecho de forma accidental de radiografías que muestran múltiples áreas escleróticas en diversos huesos del esqueleto. Su diagnóstico diferencial se realiza con la melorreostosis, osteopatía estriada y metástasis osteobásticas, en base a la clínica, radiología y gammagrafía. Histológicamente aparecen condensaciones focales de hueso lamelar compacto dentro de la esponjosa. Nosotros recogemos 2 casos de osteopoiquilosis y se hace a su vez un recuerdo.Osteopoikilosis, is a rare sclerosing bone dysplasia. The diagnosis is usually made incidentally from radiographs with show multiple sclerotic areas in several bones of the body. The differential diagnosis from melorheostosis, osteophatia striata and specially from osteoblastic bone metastases, on the basis of the clinical, radiological and radionuclide scanning characteristics. Histologically, there are focal condensations of compact lamellar bone within the spongiosa. We report two case osteopoikilosis

Electric field control of exchange bias in multiferroic epitaxial heterostructures

The magnetic exchange bias between epitaxial thin films of the multiferroic (antiferromagnetic and ferroelectric) hexagonal YMnO3 oxide and a soft ferromagnetic (FM) layer is used to couple the magnetic response of the ferromagnetic layer to the magnetic state of the antiferromagnetic one. We will show that biasing the ferroelectric YMnO3 layer by an appropriate electric field allows modifying and controlling the magnetic exchange bias and subsequently the magnetotransport properties of the FM layer. This finding may contribute to pave the way towards a new generation of electric-field controlled spintronics devices.Comment: 15 pages, 5 figures, submitte
