Växter behöver ljus för att växa. Ljuset omvandlas till kemisk energi genom fotosyntes i växtens blad. Den kemiska energin kan sedan användas av växten. Ljusabsorptionen i växter har en begränsning. Alltför mycket ljus kommer att orsaka bildning av högenergimolekyler som är skadliga för växterna. Därför måste växter justera mängden ljus som tas upp. Ljuset i miljön förändras ständigt och exponerinLight is essential for plants and algae to process photosynthesis. However, excess of light will cause damage to the organism. A process called non-photochemical quenching (NPQ) is an important way for these organisms to protect themselves from photo oxidative damage. The NPQ process is depend on the xanthophyll cycle in thylakoids, which is controlled by the Violaxanthin de-epoxidase (VDE) and ze

Background: Non-beta-hemolytic streptococci (NBHS) are a common cause of infective endocarditis (IE). Echocardiography is used to diagnose IE, but it is not known which patients with NBHS bacteremia should undergo echocardiography.Method: Medical records of patients with NBHS bacteremia in southern Sweden from 2012-2014 were studied retrospectively. The patients were divided into two cohorts. In t

Purpose:To find out differences in cerebral blood volume (CBV) maps derived from dynamic susceptibility contrast-enhanced magnetic resonance imaging (DSCE-MRI) in glioblastomas and cerebral metastases. The main purpose was to compare CBV maps between metastases with different primary malignancies. Furthermore the metastasis group was compared with the glioblastoma group.Method:Conventional imagi
