Quantitative Analysis of Seed Surface Tubercles in Silene Species

In the Caryophyllaceae, seed surfaces contain cell protrusions, of varying sizes and shapes, called tubercles. Tubercles have long been described in many species, but quantitative analyses with measurements of size and shape are lacking in the literature. Based on optical photography, the seeds of Silene were classified into four types: smooth, rugose, echinate and papillose. Seeds in each of these groups have characteristic geometrical properties: smooth seeds lack tubercles and have the highest values of circularity and solidity in their lateral views, while papillose seeds have the largest tubercles and lowest values of circularity and solidity both in lateral and dorsal views. Here, tubercle width, height and slope, maximum and mean curvature values and maximum to mean curvature ratio were obtained for representative seeds of a total of 31 species, 12 belonging to Silene subg. Behenantha and 19 to S. subg. Silene. The seeds of the rugose type had lower values of curvature. Additionally, lower values of curvature were found in species of S. subg. Silene in comparison with S. subg. Behenantha. The seeds of S. subg. Behenantha had higher values of tubercle height and slope and higher values of maximum and average curvature and maximum to mean curvature ratio.Project “CLU-2019-05-IRNASA/CSIC Unit of Excellence”, funded by the Junta de Castilla y León and co-financed by the European Union (ERDF “Europe drives our growth”)

Characterization of volatile compounds of cooked wild Iberian red deer meat extracted with solid phase microextraction and analysed by capillary gas chromatography - mass spectrometry

Wild Iberian red deer meat demand and interest are increasing and, therefore, an in-depth characterization of meat quality is needed to meet consumer demands. The objective of the present work was to assess, for the first time, the volatile profile of cooked wild sport-hunted Iberian red deer meat. Twenty-three loin samples from male red deer (Cervus elaphus hispanicus) were cooked and the volatile profile was analysed using solid phase microextraction, followed by capillary gas chromatography-mass spectrometry. Fifty-five volatile compounds were found. The major ones in number and relative abundance were aldehydes (84%), followed by alcohols (11%), hydrocarbons (2.4%), ketones (1.7%), furans (0.34%) and sulphur compounds (0.18%). Hexadecanal was the major compound and other long-chain compounds such as (E)-2-tetradecen-1-ol or 2-pentadecanone were also reported in considerable abundance. Several compounds related to grass-based diets were identified (2,3-octanedione, hexadecane or 1-pentadecanol). Odour impact ratio of volatile compounds was calculated and dimethyl trisulphide, (E,E)-2,4-decadienal, decanal and dodecanal were the most odorant compounds affecting the flavour of the cooked deer meat.Gobierno Vasco | Ref.

Efficacy of a computerized cognitive training application on cognition and depressive symptomatology in a group of healthy older adults: a randomized controlled trial

[Abstract] Objective. The purpose of this study was to evaluate the efficacy of a multimedia and interactive cognitive program on cognition and depressive symptomatology in healthy older adults. Methods. Adults aged ≥65 years were randomly assigned to two groups: the experimental group in which the participants received a computerized cognitive training application; and the control group in which the participants received no intervention during the protocol. Performance on the mini-mental state examination (MMSE) and the short-form of the geriatric depression scale (GDS-SF) were analysed using a three-way repeated-measure analysis of variance. Results. To determine cognition after the training, the cognitive program was used and the results were assessed using the MMSE, indicating that the significant time effects within the groups reflected the score for cognitive assessment that was significantly better after the intervention in the experimental group. No significant differences were observed with regard to the depressive symptomatology or between the groups according to sex or educational level on the two dimensions previously established (cognition and depressive symptomatology). Conclusion. The development of technological applications for intervention in older adults is increasing. Based on the established objective, we can conclude that the computerized intervention may constitute a good alternative to enhance the cognitive status in older people

Estilos de aprendizaje del alumnado de ingeniería: curso, rendimiento y género

Los Estilos de Aprendizaje son el conjunto de rasgos cognitivos, fisiológicos y afectivos indicadores de cómo el alumnado percibe, interacciona y responde a los diferentes ambientes del aprendizaje. Cada alumno/a tiene su propio estilo de aprendizaje de adquirir los conocimientos. Los estudiantes, además de utilizar sus habilidades cognitivas y meta cognitivas, han de saber también jerarquizar, organizar y priorizar su aprendizaje. Si bien el estudio de los Estilos de Aprendizaje es muy común en los niveles de educación obligatoria, son menos los trabajos realizados en la enseñanza superior. En el presente estudio se reconoce a los estilos de aprendizaje como recursos didácticos imprescindibles para orientar un aprendizaje significativo. El estudio se ha llevado a cabo con alumnos universitarios de ingeniería. Se emplea un diseño metodológico descriptivo, no experimental y de corte transversal realizado en la carrera Ingeniería Forestal de la Universidad de Pinar del Río (Cuba). Un total de 120 estudiantes universitarios participaron en este estudio (53.3% mujeres y 46.6 % hombres). Los participantes han realizado el Cuestionario Honey-Alonso de Estilos de Aprendizaje (CHAEA). Las respuestas permitieron determinar el perfil de estilos de aprendizaje del alumnado, siendo el estilo reflexivo el de mayor representatividad, seguido de los estilos teórico, activo y pragmático. No se detectaron diferencias estadísticamente significativas en los estilos de aprendizaje entre los años académicos para los varones, pero sí se detectaron para las mujeres. Se evidencia una evolución de los estilos reflexivo y teórico con el nivel de profesionalización de los alumnos en la medida que transitan por los cursos académicos, estando en correspondencia con los mejores rendimientos académicos alcanzados. El estudio evidenció se trata de un valioso recurso que enriquece la orientación de la enseñanza en función de la diversidad y la mejora de los aprendizajes. Se analizan sus efectos sobre la formación de los ingenieros y se discute las fortalezas y debilidades en el campo aplicado de la enseñanza superio

Sex-Differences in Health-Related Characteristics of Senior Center Users: The VERISAÚDE Study

[Abstract] Background: We explored sex-related differences in sociodemographic, medical, psychological, and functional conditions in older adults attending to senior citizens’ centers. Materials and Methods: An exploratory study was conducted as part of the VERISAÚDE project, a cross-sectional population-based study of individuals aged ≥65 years enrolled in senior community centers located in Galicia, Northwest of Spain (n = 749). A comprehensive gerontological evaluation was used to assess the social, medical, psychological, and functional characteristics of the sample. Results: Women presented a higher prevalence of frailty (p = 0.017), a higher risk of malnutrition (p = 0.029), more medication consumption (p = 0.002), and polypharmacy (p = 0.008), higher depressive scores (p = 0.007), and lower cognitive scores (p = 0.045) than men, who showed a higher prevalence of hearing impairment (p = 0.034), toxic habits (all ps = 0.0001), and comorbidity (p = 0.002), and better quality of life (p = 0.030), and social resources (p = 0.002). Participants considered that attending and being involved in senior centers has a positive influence on their health and promotes successful aging. Discussion: Important differences were found between women and men in health variables, suggesting that sex exerts a powerful influence on health status in older age. These differences should be identified and taking into account when designing interventions to promote active aging and to improve the quality of life of older adults. Taking a sex perspective during the evaluation process could lead to a higher number of older people being effectively treated in clinical practice.Xunta de Galicia; ED431C 2017/49Xunta de Galicia; ED431F 2017/09Xunta de Galicia; IN607C 2016/08Xunta de Galicia; EM 2012/100-VERISAÚDE ProjectThis work was supported by the Xunta de Galicia (ED431C 2017/49, ED431F 2017/09, FrailNet network IN607C 2016/08, and EM 2012/100-VERISAÚDE Project: Effectiveness of the Comprehensive Gerontological Assessment and longitudinal follow-up in the healthy aging promotion).

Application of light therapy in older adults with cognitive impairment: A systematic review

[Abstract] This systematic review aims to assess the efficacy of light therapy on behavioural and psychological symptoms of dementia (BPSD), cognition, functional status, and quality of life in older adults with cognitive impairment; and secondarily, to identify the optimal characteristics of light therapy to establish an adequate protocol for its clinical application. We searched Web of Science and Medline databases through December 2019, resulting in 36 included articles: 3 evaluated the effects on BPSD, 25 on sleep, 12 on agitation, 10 on mood, 4 on neuropsychiatric symptoms, 4 on cognition, 2 on quality of life and 2 on functional status. Literature has shown potential evidence for positive effects of light therapy on managing sleep, behavioural and mood disturbances in people with cognitive impairment, but a limited effect on cognition, quality of life and functional status. This review provides guidelines for intervention protocols with light therapy in older people with cognitive impairment.Xunta de Galicia; ED431C 2017/49Xunta de Galicia; ED431F 2017/09Xunta de Galicia; IN607C 2016/08Xunta de Galicia; IN607C 2017/0
