Pointwise Hardy inequalities and uniformly fat sets
2008
We prove that it is equivalent for domain in R n \mathbb {R}^n to admit the pointwise p p -Hardy inequality, have uniformly p p -fat complement, or satisfy a uniform inner boundary density condition.
Media and Science Policy: Who Influences Whom Regarding Complementary and Alternative Medicines Regulation
2021
This paper analyses the synergies between press and politics in the debate on the regulation of complementary and alternative medicines (CAM) in Spain between 1979 and 2018. We argue that longitudinal analysis and comparison of this interaction and synergy reveal how the mainstream discourse has shifted. We use a dataset of news ( N = 2,059), a news sample ( n = 325) and a dataset of parliamentary records ( N = 86). Using both quantitative and qualitative approaches, the dynamics of the interaction between the different institutions and actors involved is assessed. Specifically, the study analyses the media and parliamentary attention to CAM issues (agenda setting), how CAM is addres…
Lauroside B, a Megastigmane Glycoside from Laurus Nobilis (Bay Laurel) Leaves, Induces Apoptosis in Human Melanoma Cell Lines by Inhibiting NF-κB Act…
2010
Malignant melanoma is a highly aggressive tumor that frequently resists chemotherapy, so the search for new agents for its treatment is of great importance. In the present study, the antiproliferative propensity against human melanoma cell lines of lauroside B (1), a megastigmane glycoside isolated from Laurus nobilis (bay laurel) leaves, was investigated. This compound suppressed the proliferation of three human melanoma cell lines, namely, A375, WM115, and SK-Mel-28. The 1-induced inhibition of human melanoma cell proliferation was due to the induction of apoptosis, as demonstrated by FACS analysis with annexin V/PI staining and confirmed by activation of caspase-3 and by the cleavage of …
ISOLATION OF RAT CDNA CLONES CODING FOR THE AUTOANTIGEN SS-B/LA - DETECTION OF SPECIES-SPECIFIC VARIATIONS
1993
Clones of cDNA coding for the autoantigen La (or SS-B) were isolated from a library made from rat liver. A comparison of the rat La cDNA (encoding from nt 38 to 1281 for rat La protein) with the sequences known for human and bovine La protein resulted in the identification of species-specific inserts. The inserts seem to be the result of multiplication of flanking sequences during evolution. In addition to these variations, we observed that rat La cDNAs exhibit non-canonical polyadenylation sites. Finally, a databank search resulted in the identification of a DNA sequence originally termed as TAG or TSG20X (GenBank accession No. X61893) which represents the C terminus of mouse La/SS-B prote…
Noncanonical RNAs from transcripts of the Drosophila muscleblind gene.
2006
It has become increasingly evident that eukaryotic cells produce RNA molecules from coding genes with constitutions other than those of typically spliced mRNA transcripts. Here we describe new cDNAs from the Drosophila melanogaster muscleblind (mbl ) locus that identify two such atypical RNA molecules: RNAs containing an incomplete exon 2 tandem repetition (mblE2E2#) or having exons with a different order compared to the corresponding genomic DNA (mblE2E3#E2#; exon scrambling). The existence of exon duplications and rearrangements in the genomic locus that might explain such cDNAs was ruled out by genomic Southern blotting and in silico analysis of the Drosophila genome sequence. The incomp…
Drimane Sesquiterpenoids from Marasmius sp. Inhibiting the Conidial Germination of Plant-Pathogenic Fungi
2012
From the basidiomycete Marasmius sp., strain IBWF 96046, three new sesquiterpenoids based on the drimane skeleton were isolated and named marasmene B and marasmals B and C. In this study, their isolation, structure elucidation, and biological evaluation are described. The compounds have a pronounced inhibitory effect on the conidial germination of several plant-pathogenic fungi.
C3 reference typing report and nomenclature revision.
1990
As the result of reference typing, two 'new' variants could be provisionally accepted (C3F045 and C3F015). The list of variants of the C3 polymorphism includes now 2 common and 29 rare variants.
Functional size of complement and perforin pores compared by confocal laser scanning microscopy and fluorescence microphotolysis
1991
Abstract Confocal laser scanning microscopy and fluorescence microphotolysis (also referred to as fluorescence photobleaching recovery) were employed to study the transport of hydrophilic fluorescent tracers through complement and perforin pores. By optimizing the confocal effect it was possible to determine the exclusion limit of the pores in situ, i.e. without separation of cells and tracer solution. Single-cell flux measurements by fluorescence microphotolysis yielded information on the sample population distribution of flux rates. By these means a direct comparison of complement and perforin pores was made in sheep erythrocyte membranes. In accordance with previous studies employing a v…
Management of depressive symptoms in peri- and postmenopausal women: EMAS position statement.
2019
Introduction: Globally, the total number of people with depression exceeds 300 million, and the incidence rate is 70 % greater in women. The perimenopause is considered to be a time of increased risk for the development of depressive symptoms and major depressive episodes. Aim: The aim of this position statement is to provide a comprehensive model of care for the management of depressive symptoms in perimenopausal and early menopausal women, including diagnosis, treatment and follow-up. The model integrates the care provided by all those involved in the management of mild or moderate depression in midlife women. Materials and methods: Literature review and consensus of expert opinion. Summa…
More Than Meets the Eye: Toward a Post-Materialist Model of Consciousness.
2015
Commonly accepted models of human consciousness have substantial shortcomings, in the sense that they cannot account for the entire scope of human experiences. The goal of this article is to describe a model with higher explanatory power, by integrating ideas from psychology and quantum mechanics. In the first part, the need for a paradigm change will be justified by presenting three types of phenomena that challenge the materialistic view of consciousness. The second part is about proposing an alternative view of reality and mind–matter manifestation that is able to accommodate these phenomena. Finally, the ideas from the previous parts will be combined with the psychological concepts deve…
