Phytochemical profile and insecticidal activity of Drimia pancration (Asparagaceae) against adults of Stegobium paniceum (Anobiidae)

2020

Chemical and spectroscopic investigation of the bulbs of Drimia pancration resulted in the isolation of one known flavonol (1), never isolated from this plant species, and of three previously described steroidal saponins (2–4), but whose configuration at their stereogenic centres was not clearly determined. By mean of 1H NMR, 13C NMR, nuclear overhauser effects (NOE) and two-dimensional NMR spectra the full stereochemical structures of compounds 2–4 were proved and all the 1H and 13C signals were assigned. Furthermore, the methanol and butanol extracts of D. pancration were tested against adults of Stegobium paniceum beetles. Despite the non-significant results regarding the repellent activ…

Apical dendritic spines and axonic terminals in the bipyramidal neurons of the dorsomedial cortex of lizards (Lacerta).

1984

Gold-toned bipyramidal neurons of the dorsomedial cortex of Lacerta have been studied using light and electron microscopy. The spines have been classified as stubby, mushroom-shaped or thin. Thin and mushroom-shaped spines are only found on proximal and intermediate dendritic segments, whereas stubby spines are found on distal dendritic segments. A Timm's method modification for electron microscopy (sulphide-osmium procedure) has been used. Timm-positive axonal endings usually synapse on thin and mushroom-shaped spines, whereas Timm-negative axonal endings usually synapse on stubby spines. Timm-positive afferents and their post-synaptic spines on bipyramidal neurons of Lacerta's dorsomedial…

Retoryka strachu w czasie pandemii Covid-19. Przypadek Emmanuela Macrona

2021

Artykuł prezentuje wyniki analizy telewizyjnego orędzia prezydenta Francji Emmanuela Macrona z dnia 16 marca 2020 roku. Stanowi ono przyczynek do wskazania na znaczenie we współczesnym dyskursie politycznym odwoływania się do logiki strachu i poczucia zagrożenia. Analiza treści pozwoliła wskazać najważniejsze cechy retoryki strachu, jaka zdominowała prezydenckie przemówienie pełne sensacyjnych metafor i wojennych odniesień, będących doskonałym przykładem moralnej paniki w czasie kryzysu, w którym zwiększa się zapotrzebowanie na informację. Analizą dyskursu objęto leksykalne i składniowe środki językowe, gdzie niezwykle częste metafory wojenne dają możliwość manipulacji opinią społeczną i wd…

Psychometrics of the Spanish Version of the Screen for Adult Anxiety Related Disorders (SCAARED)

2021

Objectives: To translate and validate the Screen for Adult Anxiety Related Disorders (SCAARED) questionnaire into Spanish.Method: The original SCAARED was translated into Spanish and administered to a non-clinical sample of 131 university students (92.4% women, mean age 22 years) in Valencia, Spain. To assess the concurrent validity of the SCAARED, the Depression, Anxiety and Stress Scale−21(DASS) and the Beck's Anxiety Inventory (BAI) were also administered. Test-retest reliability was evaluated 2 weeks after the first administration.Results: The internal consistency of SCAARED was high (α = 0.91) and the stability of the measurement was also high (test-retest 0.81). The results of the Exp…

Is quality of life different between diabetic and non-diabetic people? The importance of cardiovascular risks.

2017

BackgroundTo analyse and compare the impact of cardiovascular risk factors and disease on health-related quality of life (HRQoL) in people with and without diabetes living in the community.MethodsWe used data of 1,905 people with diabetes and 19,031 people without diabetes from the last Spanish National Health Survey (years 2011 +/- 2012). The HRQoL instrument used was the EuroQol 5D-5L, based on time trade-off scores. Matching methods were used to assess any differences in the HRQoL in people with and without diabetes with the same characteristics (age, gender, education level, and healthy lifestyle), according to cardiovascular risk factors and diseases. Disparities were also analysed for…

Women’s knowledge and attitudes towards cervical cancer prevention: A qualitative study in the Spanish context

2021

Aims and objectives To explore the knowledge, attitudes and practices related to cervical cancer and its prevention in Spain. Background Worldwide, women's knowledge about cervical cancer is low, and their attitudes towards its prevention are good, but they do not correlate with the screening uptake. Although the rates of Spanish women performing cervical cancer screening are mostly acceptable, their knowledge and attitudes about it have not been explored. Design Qualitative descriptive study. Methods Three focus groups were conducted, with 21 women aged 25 to 65 years. Participants were recruited through convenience sampling. For intragroup homogeneity, women participated in age groups. Th…

Zinc-positive boutons in the cerebral cortex of lizards show glutamate immunoreactivity

1991

Zinc-positive boutons, originating in the medial cortex of lizards, exhibit glutamate immunoreactivity. This finding supports the presumed homology between lizard zinc-positive boutons and the hippocampal mossy fibres of mammals, which are also glutamate-immunoreactive and zinc-positive. Zinc-positive boutons of lizards contain a chelatable pool of zinc located in the hippocampal mossy fibres of mammals. These synaptic systems also contain glutamate, which indicates a possible simultaneous action of zinc and glutamate during synaptic transmission.

Timm-staining intensity is correlated with the density of Timm-positive presynaptic structures in the cerebral cortex of lizards

1987

In cortical areas of the lizard, Podarcis hispanica, Timm staining reveals a distinct pattern of lamination. At the electron-microscope level, virtually all of the reaction product is located in the synaptic vesicles of Timm-positive boutons. Using linear-regression analysis, the area density of Timm-positive bouton profiles as well as the numerical and volume density of stained vesicles were found to be closely correlated with the light-microscopic densitometric values obtained for each Timm-positive cortical zone. We discuss the possibility of estimating stereological electron-microscopic data parameters from densitometric measurements at the light-microscope level.
