2. 1. Ultraviolet radiation cataract

   Author : Konstantin Galichanin; Karolinska Institutet; Karolinska Institutet; []
   Keywords : lens;

   Abstract : Cataract is the leading cause of blindness in the world. Epidemiological and experimental evidence supports a link between mid-range ultraviolet radiation (UVR-B) exposure and the development of cataract. READ MORE

4. 2. Regulation of UV induced apoptosis in human melanocytes

   Author : Cecilia Bivik; Inger Rosdahl; Karin Öllinger; Maria Shoshan; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; apoptosis; UV; melanocyte; lysosome; cathepsin; Bcl-2; Bax; Hsp70; JNK; Dermatology and venerology; Dermatologi och venerologi;

   Abstract : Malignant melanoma arises from the pigment producing melanocytes in epidermis and is the most aggressive type of skin cancer. The incidence of malignant melanoma is increasing faster than any other type of cancer in white population worldwide, with a doubling rate every 10-20 years. READ MORE

6. 4. Ultraviolet vertical-cavity surface-emitting lasers and vertical microcavities for blue lasers

   Author : Filip Hjort; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GaN; ultraviolet; microcavity; electrical conductivity; vertical-cavity surface-emitting laser; AlGaN; electrochemical etching; nanostructures; distributed Bragg reflector;

   Abstract : III-nitride materials are used for ultraviolet (UV) and visible light emitters. One such light source is the vertical-cavity surface-emitting laser (VCSEL) that could find applications within areas ranging from sterilization and medical treatment to car headlights and augmented reality displays.

7. 5. Daphnids adaptive strategies to UV radiation

   Author : Carla Eloisa Fernández; Avdelningen för Teknisk vattenresurslära; []
   Keywords : Cladocera; Zooplankton; Andean lakes; Daphnia; Ultraviolet radiation; Migration strategy; Photo-protection;

   Abstract : This thesis focuses on the adaptive strategies of daphnids that allows them to maintain stable populations while deal with UV radiation, highlighting the differences in the responses that populations with different evolutionary histories may have.Although exposition to lethal doses in nature is unlikely, sub-lethal UV-B radiation doses may have strong impacts on zooplankton.
