Sun exposure and PDZK1 genotype modulate PDZK1 gene expression in normal skin

2020

Human skin pigmentation results from the enzymatically controlled synthesis of melanin pigments in specialized organelles (melano‐somes) produced within epidermal melanocytes, followed by their transfer to neighboring keratinocytes and their distribution through‐out the epidermis.1 Constitutive skin pigmentation seems to be mostly genetically determined,2 being altered by numerous intrinsic and extrinsic factors affecting the epidermal melanin unit

Governance through Economic Paradigms: Addressing Climate Change by Accounting for Health

2016

"Climate change is a major challenge for sustainable development, impacting human health, wellbeing, security, and livelihoods. While the post-2015 development agenda sets out action on climate change as one of the Sustainable Development Goals, there is little provision on how this can be achieved in tandem with the desired economic progress and the required improvements in health and wellbeing. This paper examines synergies and tensions between the goals addressing climate change and economic progress. We identify reductionist approaches in economics, such as 'externalities', reliance on the metric of the Gross Domestic Product, positive discount rates, and short-term profit targets as so…

Knuta Hamsuna recepcija latviešu literatūrā 20.gs.sākumā un 21.gs. sākumā

2017

Bakalaura darbā pētīta Knuta Hamsuna popularitāte 20. gadsimta sākuma latviešu literatūrā un recepcija kritikā, kā arī apskatīta autora aktualitāte 21. gadsimtā. Darba mērķis ir noskaidrot kādus poētikas veidošanas paņēmienus latviešu autori aizguvuši no Knuta Hamsuna. Ir veikts salīdzinošs pētījums, sastatot tādu latviešu autoru kā Jānis Akuraters, Gunars Janovskis un Inga Ābele darbus ar norvēģu autora daiļradi. Pētījuma rezultātā apstiprinājusies hipotēze, ka iespaids uz 20. gadsimta literatūru bijis ievērojamāks, savukārt 21. gadsimtā aktualitāte zudusi. Noskaidrots, ka latviešu rakstnieki pielietojuši Knutam Hamsunam raksturīgo tēla psiholoģijas atklāsmi, dabas tēlojuma nozīmību daiļda…

Classification of Spanish Unifloral Honeys by Discriminant Analysis of Electrical Conductivity, Color, Water Content, Sugars, and pH

2001

To ascertain the most discriminant variables for seven types of Spanish commercial unifloral honeys, stepwise discriminant analysis was performed. Fifteen parameters [pH; water content; electrical conductivity; x, y, and L, chromatic coordinates from the CIE-1931 (xyL) color space; fructose; glucose; sucrose; maltose; isomaltose; maltulose; kojibiose; and the fructose/glucose and glucose/water ratios] were considered. The studied honey types were rosemary, citrus, lavender, sunflower, eucalyptus, heather, and forest. The most discriminant variables, as selected by the multivariate program, were electrical conductivity, color (x, y, L), water content, fructose, and sucrose. All sunflower, eu…

Impact of spatial resolution and satellite overpass time on evaluation of the surface urban heat island effects

2012

Abstract Surface Urban Heat Island (SUHI) effect is defined as the increased surface temperature in urban areas in contrast to surrounding cooler temperatures in rural areas. In this paper, we study the characteristics that a spaceborne sensor must satisfy in terms of spatial resolution and overpass time to properly monitor the SUHI effect. For this, Land Surface Temperature (LST) maps, generated at different spatial resolution using the Airborne Hyperspectral Scanner (AHS) imagery, and in situ data of air temperature and LST obtained from the framework of the Dual-use European Security IR Experiment 2008 have been considered for the city of Madrid (Spain). The results showed that (1) spati…

Vertical profiling of Saharan dust with Raman lidars and airborne HSRL in southern Morocco during SAMUM

2009

Three groundâÂ�Â�based Raman lidars and an airborne highâÂ�Â�spectralâÂ�Â�resolution lidar (HSRL) were operated during SAMUM 2006 in southern Morocco to measure height profiles of the volume extinction coefficient, the extinctionâÂ�Â�toâÂ�Â�backscatter ratio, and the depolarization ratio of dust particles in the Saharan dust layer at several wavelengths. Aerosol Robotic Network (AERONET) Sun photometer observations and radiosounding of meteorological parameters complemented the groundâÂ�Â�based activities at the SAMUM station of Ouarzazate. Four case studies are presented. Two case studies deal with the comparison of observations of the three groundâÂ�Â�based lidars during a heavy du…

Insights About the Neuroplasticity State on the Effect of Intramuscular Electrical Stimulation in Pain and Disability Associated With Chronic Myofasc…

2018

Background: There is limited evidence concerning the effect of intramuscular electrical stimulation (EIMS) on the neural mechanisms of pain and disability associated with chronic Myofascial Pain Syndrome (MPS). Objectives: To provide new insights into the EIMS long-term effect on pain and disability related to chronic MPS (primary outcomes). To assess if the neuroplasticity state at baseline could predict the long-term impact of EIMS on disability due to MPS we examined the relationship between the serum brain-derived-neurotrophic-factor (BDNF) and by motor evoked potential (MEP). Also, we evaluated if the EIMS could improve the descending pain modulatory system (DPMS) and the cortical exci…
