Determination of gibberellic acid in a commercial seaweed extract by capillary electrophoresis

Gibberellic acid (GA3) is an important plant growth regulator used in agriculture. This work has developed and validated a simple method for the quantification of GA3 in a seaweed extract product using capillary electrophoresis with direct UV detection. A fused-silica capillary of 50 µm inner diameter and 30 cm of effective length with extended light path, 50 mmol.L-1 of borate buffer as background electrolyte solution (pH 9.11), voltage of +30kV applying hydrodynamic injection of 50 mbar for 5 s and length detection of 200 nm were employed. The method was validated according to the International Conference Harmonisation guidelines. Satisfactory results in the range of 10 – 100 mg.L-1 were obtained for precision (RSD below 3.62%), linearity (R2: 0.9976, lack of fit test p > 0.05), specificity and accuracy for which the limit of detection and quantitation were 3.07 and 9.29 mg.L-1, respectively. The results indicate that the method is suitable for implementation in agroindustry in order to assure the quality control of GA3 of seaweed products

Analysis of the Relationship between Emotional Intelligence, Resilience, and Family Functioning in Adolescents’ Sustainable Use of Alcohol and Tobacco

The use of alcohol and tobacco is related to several variables, which act as risk or protective factors depending on the circumstances. The objectives of this study were to analyze the relationship between emotional intelligence, resilience, and family functioning in adolescent use of alcohol and tobacco, and to find emotional profiles for their use with regard to self-concept. The sample was made up of 317 high school students aged 13 to 18, who filled out the Brief Emotional Intelligence Inventory, the Resilience Scale for Adolescents, the APGAR Scale, the Alcohol Expectancy Questionnaire–Adolescents, and the Five-Factor Self-Concept Questionnaire. The results revealed that emotional intelligence and resilience, specifically stress management and family cohesion, were significant in the group of non-users. Family functioning acts as a predictor for the onset of use of tobacco and alcohol. Positive expectancies about drinking alcohol were found to be a risk factor, and the intrapersonal factor was found to be protective. Both stress management and family cohesion were protective factors against smoking. Furthermore, cluster analysis revealed the emotional profiles for users of both substances based on self-concept. Finally, the importance of the direction of the relationship between the variables studied for intervention in this problem should be mentioned. Responsible use by improving adolescent decision-making is one of the results expected from this type of intervention

Emotional Effects of the Duration, Efficiency, and Subjective Quality of Sleep in Healthcare Personnel

Considering that both sleep quality and duration are linked to psychological variables, this study analyzed the relationships between sleep components and emotional intelligence and the effects that sleep duration has on stress management and mood in a sample of nurses. The sample was made up of 1073 professionals. Data were collected by the Pittsburgh Sleep Quality Index and the Brief Emotional Intelligence Inventory for Senior Citizens. The results showed that the components of sleep quality were negatively related to stress management and mood. Furthermore, nurses who had short sleep patterns also had low moods and high stress levels. This study emphasizes the importance of subjective sleep quality as a necessary resource for professionals to manage stressful situations and mood and improve their relations with their patients and with each other

Políticas culturales y participación en colombia

El presente análisis sobre las políticas culturales en Colombia, comienza en el año 1968 durante el cual se funda CoJcultura,ya que desde este momento el Estado reconoce a la cultura como ente independiente y no sólo como apéndice de la educación; hasta el año 2003, estableciendo una división en 1997, por tratarse de! año de la creación del Ministerio de Cultura. Se realizó un recorrido por los principales documentos que dan cuenta del proceso evolutivo de las políticas culturales en el país desde tres categorías fundamentales: relación Estado-cultura, participación y descentralización. El tratamiento que se da a la políticas culturales, varia según el gobierno de turno y las prioridades que este establezca. En Colombia, aunque hay avances notorios en materia participativa, evidenciados en procesos novedosos como la Constitución de 1991, Yen e! aspecto cultural en el Plan Nacional de Cultura (2001-2010), se reconocen vacíos ynecesidades que superan e! discurso de la diversidad cultural. Palabras clave: estado, cultura, participación, descentralización

Association between elasticity of tissue and pain pressure threshold in the tender points present in subjects with fibromyalgia: a cross‑sectional study

Fibromyalgia (FM) is a multicomponent illness and despite its worldwide prevalence, a complete understanding of its aetiology and pathogenesis remains unclear. The goal of the study is to analyze the level of association between elastic properties of tissue measured by strain elastography (SEL) and pain pressure threshold (PPT) in the characteristic painful points described in patients suffering from FM. This was a cross-sectional, observational study. A sample comprised of 42 subjects with FM was recruited from a private care centre. The occiput, low cervical, trapezius, supraspinatus, paraspinous, lateral pectoral, second rib, lateral epicondyle, medial epicondyle, gluteus, greater trochanter, knee, and anterior tibial PPTs were bilaterally assessed using a standard pressure algometer and elastic properties of tissue were evaluated by SEL. Linear regression analysis showed significant associations between SEL and dominant trapezius PPT (β = 0.487, 95% CI [0.045, 0.930], p = 0.032) after adjustments for the age, body mass index, and menopause status (higher SEL and higher pain sensitivity). No significant associations between SEL and the other PPTs variables were found in women diagnosed with FM. The PPT of the dominant trapezius is associated with SEL measurements in subjects suffering from FM. More studies are required to fully explain the underlying mechanisms

Engineering biocatalysts for the anaerobic recycling of toxic aromatic hydrocarbons

En: 1st Spanish National Conference on Advances in Materials Recycling and Eco – Energy Madrid, 12-13 November 2009.-- Editors: F. A. López, F. Puertas, F. J. Alguacil and A. Guerrero.-- 3 pages.Azoarcus sp. CIB is a denitrifying betaproteobacterium that uses different aromatic compounds, including toxic hydrocarbons such as toluene and m-xylene, as sole carbon sources, and is susceptible of genetic manipulation. To acquire a global view of all the genetic determinants involved in the anaerobic catabolism of aromatic compounds in strain CIB, and to accelerate and complete our understanding about this anaerobic catabolism, we have performed a genomic survey in the recently sequenced genome of this strain. This information paves the way for a pathway engineering approach within the field of anaerobic degradation of aromatics.Peer reviewe

Learning process and improvement of point-of-care ultrasound technique for subxiphoid visualization of the inferior vena cava

Background: Medical residents' training in ultrasonography usually follows the recommendations of the American College of Emergency Physicians (ACEP), even though these do not provide specific technical guidelines. Adequate training is considered to require 25 practical iterations in the majority of ultrasound procedures. However, the effectiveness of this approach has not been verified experimentally. We set out to determine the number of repetitions required for an acceptable ultrasound procedure of the inferior vena cava (IVC), as an important and emerging ultrasound procedure in cardiology. Methods: Using three human models, each of eight medical residents in the Emergency Medicine (EM) Program at the Universidad del Rosario performed 25 iterations of the recommended procedure, with image quality evaluation by an EM physician expert in the technique. Logistic regression analysis was used to determine the lowest number of repetitions required to achieve an adjusted probability of success of 80 and 90 %, respectively. Results: We obtained 200 ultrasound images. The percentage success by each resident ranged from 52 to 96 %. There was no statistical significance in the relation between gender and success (p = 0.83), but there was an association between year of residency and success (p  less than  0.001). The average time taken for each procedure was 17.3 s (SD 8.1); there was no association between the time taken and either repetition number or image quality. We demonstrate that eleven repetitions are required to achieve acceptable image quality in 80 %, and that 21 repetitions are required to achieve acceptable image quality in 90 %. Conclusions: This is the first study to formally evaluate the effectiveness of recommended training in ultrasound techniques. Our findings demonstrate that training comprising 25 procedural repetitions is easily sufficient to achieve optimal image quality, and they also provide empiric knowledge toward elucidating the times and minimum repetitions needed to acquire and improve ultrasonographic technique in novice operators to a level which fulfills quality requirements for interpretation. © 2016, Gómez Betancourt et al
