  Title Alternatives to artificial lighting: Varying patterns of bio-light in architecture Type Journal Article
  Year 2020 Publication (up) Archidoct Abbreviated Journal  
  Volume 8 Issue 1 Pages 80-91  
  Keywords Lighting  
  Abstract The notion of variability is identical to the phenomenon of light.The present paper examines characteristics that shape this variability, in all forms of light, both natural and artificial, as well as light that is experimentally produced in a laboratory environment, through genetic modification of plants, in line with current trend of architectural fluidity. At a time when architecture is interacting with emerging technologies by creating parametrically changing shells and environments, that are evolving as biological models and organisms, lighting is becoming a tool for highlighting forms while ensuring the functionality of spaces. It is up to the designer to manage these variables of light in an inspired way, in order to create an elegant, sustainable and environmentally friendly environment for all beings.

  Title Prior exposure to dim light at night impairs dermal wound healing in female C57BL/6 mice Type Journal Article
  Year 2019 Publication (up) Archives of Dermatological Research Abbreviated Journal Arch Dermatol Res  
  Volume 311 Issue 7 Pages 573-576  
  Keywords Animals; mouse models; Skin; Human Health  
  Abstract Artificial light at night (LAN) is a pervasive phenomenon in today's society, and the detrimental consequences of LAN exposure are becoming apparent. LAN is associated with the increased incidence of metabolic disorders, cancers, mood alterations, and immune dysfunction in mammals. Consequently, we examined the effects of dim LAN (DLAN) on wound healing. Female C57BL/6 mice were housed for 3 weeks in DLAN or LD conditions prior to wounding. Following wounding, mice were maintained in either their previous light conditions or switched to the opposite lighting conditions for 3 weeks. DLAN prior to wounding impaired healing; specifically, mice in DLAN/DLAN had significantly larger wounds on day 8. Additionally, mice in DLAN/LD had significantly larger wounds on days 5, 7, 8, and 9, and increased average time to closure. These data demonstrate a potential harmful effect of DLAN on wound healing that should be considered and may represent a target for therapeutic intervention.

  Title Toxicity of blue led light and A2E is associated to mitochondrial dynamics impairment in ARPE-19 cells: implications for age-related macular degeneration Type Journal Article
  Year 2019 Publication (up) Archives of Toxicology Abbreviated Journal Arch Toxicol  
  Volume 93 Issue 5 Pages 1401-1415  
  Keywords Vision; age-related macular degeneration; Eye; Eye Diseases; blue light  
  Abstract Age-related macular degeneration (AMD) is a multifactorial retinal disease characterized by a progressive loss of central vision. Retinal pigment epithelium (RPE) degeneration is a critical event in AMD. It has been associated to A2E accumulation, which sensitizes RPE to blue light photodamage. Mitochondrial quality control mechanisms have evolved to ensure mitochondrial integrity and preserve cellular homeostasis. Particularly, mitochondrial dynamics involve the regulation of mitochondrial fission and fusion to preserve a healthy mitochondrial network. The present study aims to clarify the cellular and molecular mechanisms underlying photodamage-induced RPE cell death with particular focus on the involvement of defective mitochondrial dynamics. Light-emitting diodes irradiation (445 +/- 18 nm; 4.43 mW/cm(2)) significantly reduced the viability of both unloaded and A2E-loaded human ARPE-19 cells and increased reactive oxygen species production. A2E along with blue light, triggered apoptosis measured by MC540/PI-flow cytometry and activated caspase-3. Blue light induced mitochondrial fusion/fission imbalance towards mitochondrial fragmentation in both non-loaded and A2E-loaded cells which correlated with the deregulation of mitochondria-shaping proteins level (OPA1, DRP1 and OMA1). To our knowledge, this is the first work reporting that photodamage causes mitochondrial dynamics deregulation in RPE cells. This process could possibly contribute to AMD pathology. Our findings suggest that the regulation of mitochondrial dynamics may be a valuable strategy for treating retinal degeneration diseases, such as AMD.

  Title How Early Do Birds Start Chirping? Dawn Chorus Onset and Peak Times in a Neotropical City Type Journal Article
  Year 2019 Publication (up) Ardeola Abbreviated Journal  
  Volume 66 Issue 2 Pages 327-341  
  Keywords Animals  
  Abstract Urbanisation poses important challenges for animal communication. Avian dawn choruses are a prominent component of urban soundscapes and have received attention in recent urban ecology studies. Current evidence based on comparisons of urban and non-urban sites suggest that urbanisation is associated with earlier dawn chorus singing activity. However, this phenomenon remains mainly unexplored in tropical cities. We here assessed dawn chorus onset and peak times in two contrasting conditions of the urbanisation intensity gradient (i.e., intra-urban and peri-urban forested areas) of a Neotropical city, Xalapa in Mexico, assessing relationships with noise at sunrise and artificial light at night. We found no differences in dawn chorus onset or singing peak times when contrasting intra- and peri-urban areas. However, we found non-significant trends for earlier chorus onsets and peak times with increasing noise levels. Our results show no relationship between artificial light at night and dawn chorus timing, adding evidence to recent studies showing that light pollution does not seem to be determinant in the dawn choruses of tropical birds. Further research is needed to include a wider array of urbanisation conditions and drivers of the singing routines of urban tropical birds. —Marín-Gómez, O.H. & MacGregor-Fors, I. (2019).
