Standardised spider (Arachnida, Araneae) inventory of Lammi, Finland
2020
In June 2019, an ecology field course of the University of Helsinki was held at Lammi Biological Station, Southern Finland. Within this course, the students familiarised themselves with field work and identification of spiders and explored the diversity of species in the area. Three sampling plots were chosen, one in grassland and two in boreal forest, to demonstrate the sampling techniques and, by applying a standardised protocol (COBRA), contribute to a global spider biodiversity project. The collected samples contained a total of 3445 spiders, of which 1956 (57%) were adult. Only adult spiders were accounted for in the inventory due to the impossibility of identification of juveniles. A …
Quenching of gA deduced from the β-spectrum shape of 113Cd measured with the COBRA experiment
2020
A dedicated study of the quenching of the weak axial-vector coupling strength gA in nuclear processes has been performed by the COBRA collaboration. This investigation is driven by nuclear model calculations which show that the β-spectrum shape of the fourfold forbidden non-unique decay of 113Cd strongly depends on the effective value of gA. Using an array of CdZnTe semiconductor detectors, 45 independent 113Cd spectra were obtained and interpreted in the context of three nuclear models. The resulting effective mean values are g‾A(ISM)=0.915±0.007, g‾A(MQPM)=0.911±0.013 and g‾A(IBFM-2)=0.955±0.022. These values agree well within the determined uncertainties and deviate significantly from th…
La preferencia de la vía civil a la penal para recobrar la posesión en las ocupaciones pacíficas de inmuebles.
2021
En el presente artículo se analizar los motivos por los que en las ocupaciones pacíficas de inmuebles sin consentimiento el recurso a la vía civil es más eficaz que la penal para la recuperación de la posesión. Dos son las causas por los que estimamos preferible la vía civil: la negativa de un sector de la judicatura para aplicar el delito de usurpación de inmuebles del art. 245.2 CP en los casos que no son graves y la no aplicación de la medida cautelar de devolución anticipada de los inmuebles ocupados a sus dueños. La vía civil es la más efectiva para la recuperación de la vivienda ocupada desde que se modificó el interdicto de recobrar la posesión mediante la Ley 5/2018.
alpha-Bungarotoxin, kappa-bungarotoxin, alpha-cobratoxin and erabutoxin-b do not affect [3H]acetylcholine release from the rat isolated left hemidiap…
1995
Endplate preparations of the rat left hemidiaphragm were incubated with [3H]choline to label neuronal transmitter stores. Nerve evoked release of newly-synthesized [3H]acetylcholine was measured in the absence of cholinesterase inhibitors to investigate whether snake venom neurotoxins by blocking presynaptic nicotinic autoreceptors affect evoked transmitter release. Contractions of the indirectly stimulated hemidiaphragm were recorded to characterize the blocking effect of alpha-neurotoxins at the post-synaptic nicotinic receptors. Neither the long chain neurotoxins alpha-cobratoxin (1 microgram ml-1) and alpha-bungarotoxin (5 microgram ml-1) nor the short chain neurotoxin erabutoxin-b (0.1…
Confirmation of gA quenching using the revised spectrum-shape method for the analysis of the 113Cd β-decay as measured with the COBRA demonstrator
2021
In this article we present an updated spectrum-shape analysis of the $^{113}$Cd fourfold forbidden non-unique $\beta$-decay transition in order to address the quenching of the weak axial-vector coupling $g_{\rm A}$ in low-momentum exchange nuclear processes. The experimental data were collected in a dedicated low-threshold run with the COBRA demonstrator at the LNGS and resulted in 44 individual $^{113}$Cd spectra. These data are evaluated in the context of three nuclear model frameworks based on a revised version of the spectrum-shape method and the conserved vector current hypothesis. The novel idea devised in the present work is to fit the value of the small relativistic nuclear matrix e…
Aktivierung des Komplementsystems ? Ein Monopol des Immunkomplexes?
1972
Das Komplementsystem wird herkommlicherweise als ein Reaktionspartner des AgAk-Komplexes beschrieben. In jungster Zeit hat sich aber herausgestellt, das seine Aktivierung kein Monopol des Immunkomplexes bzw. des Antikorpers ist. An geeigneten Einzelfaktoren ansetzend kann man die Reaktionskette des Komplements auch unabhangig vom Antikorper auslosen. Es werden diejenigen Reaktionen beschrieben, welche, unabhangig vom Antikorper, von C1, C4 und C2 die dritte Komplementkomponente aktivieren und die Reaktionskette des restlichen Komplementsystems bis zum Terminalschritt in Gang setzen. Zu solchen Aktivatorsubstanzen gehoren Proteasen, hochmolekulare Polysaccharide (Dextran, Zymosan), Cobratoxi…
Manuel Vázquez Montalbán y sus heterónimos en la revistra "Triunfo"
2022
The volume collects and analyzes the collaborations of Manuel Vázquez Montalbán in the magazine Triunfo, from the opinion article, to the report, from the short story to the comic strip, focusing on the use of heteronomous words. Following the path of the genre, the style and the narrative perspectives of the different contributions, the fertile osmosis between literary discourse and journalistic discourse is thus verified. The weekly appeared in 1946 in Valencia, playing a role of theater and film information and criticism. Since its transfer to Madrid in 1948, the magazine expanded its interests, inserting articles on domestic and foreign policy, until, in the 1960s, it became the intelle…
Insect Immune Evasion by Dauer and Nondauer Entomopathogenic Nematodes
2021
The immune response of animals, including insects, is overcome by some parasites. For example, dauer larvae (DL) of the obligate entomopathogenic nematodes (EPNs) Heterorhabditis and Steinernema can invade insects, evade their defenses, and cause death. Although DL were long assumed to be the only infective stage of nematodes, recent reports suggest that L2-L3 larvae of facultative EPNs are also capable of killing insects. There are no studies, to our knowledge, about the role of nonimmunological barriers (the exoskeleton and its openings) in avoiding infection by DL and L2-L3 larvae, or whether these larval stages evade the host immune system in the same way. The objective of this study wa…
Integrative Gene Expression and Metabolic Analysis Tool IgemRNA
2022
ABSTRACTGenome scale metabolic modelling is widely used technique to research metabolism impacts on organism’s properties. Additional omics data integration enables a more precise genotype-phenotype analysis for biotechnology, medicine and life sciences. Transcriptome data amounts rapidly increase each year. Many transcriptome analysis tools with integrated genome scale metabolic modelling are proposed. But these tools have own restrictions, compatibility issues and the necessity of previous experience and advanced user skills. We have analysed and classified published tools, summarized possible transcriptome pre-processing, and analysis methods and implemented them in the new transcriptome…
Formation and function of a complement-activating enzyme generated from factors of guinea pig serum and cobra venom
1971
An enzymatic complex can be formed by factors from guinea pig serum and cobra venom, which is able to activate C3 bypassing C1, C4 and C2. Formation and action of the enzyme are described. The action on C3 results in an activation of the terminal complement components and in membrane destruction provided suitable membrane receptors are available.
