The transparency regulator hypothesis (TRH) proposes that ultraviolet radiation (UVR) is a main driving force behind diel vertical migration (DVM) of zooplankton in clearwater systems. While previous studies have mainly studied DVM in relation to the TRH on a spatial scale across systems we here focus on long-term trends in a single system in order to assess if UVR explains observed patterns in DV
Basic helix-loop-helix PAS domain proteins form a growing family of transcription factors. These proteins are involved in the process of adaptation to cellular stresses and environmental factors such as a change in oxygen concentration. We describe the identification and characterization of a recently cloned PAS domain protein termed Npas4 in ischemic rat brain. Using gene expression profiling fol
We have seen that protein kinase Calpha (PKCalpha) is transiently translocated to the plasma membrane by carbachol stimulation of neuroblastoma cells. This is induced by the Ca2+ increase, and PKCalpha does not respond to diacylglycerol (DAG). The unresponsiveness is dependent on structures in the catalytic domain of PKCalpha. This study was designed to investigate if and how the kinase activity a
Artikeln utgör en respons till ett föredrag om Derridas rättvisebegrepp, hållet av den isländske filosofen Björn Thorsteinson.
This article is a response to Greenbank's (2006) The academic's role: the need for a re-evaluation? It is also a contribution to the ongoing debate about the need to develop a broader view of scholarship and the different activities related to it such as 'teaching', 'research' and 'service to the community'. Arguments related to current research are presented to enhance a deeper understanding and
The traditional family unit has historically been considered a fundamental element of Vietnamese society. Despite legislation which has declared the equality of men and women, in reality, household gender roles remain fixed and often unequal, and family members are not expected to deviate from the norm. Men hold the dominant position within the household, and the belief that the husband can legiti
Introduction: Dystonia-deafness syndrome is a distinct clinical presentation within the dystonia-spectrum. Although several genetic and acquired causes have been reported, etiology remains unknown in the majority of patients. Objectives: To describe two patients with dystonia-deafness syndrome due to a beta-actin gene mutation. Methods: We report on disease course, genetic testing, and management
With the aim of clarifying critical care nursing, six critical care nurses, working in a Swedish intensive care unit (ICU) were each asked to narrate a care situation with which they had been satisfied or dissatisfied. The stories were tape-recorded and analysed using a phenomenological-hermeneutic approach inspired by the philosophy of Ricoeur. The themes uncovered in the analysis describe the nu
Introduction Lactate concentration in umbilical cord blood is an important measure of intrapartum anaerobic metabolism. The aim of the study was to compare lactate production of large‐for‐gestational‐age (LGA) fetuses against appropriate‐for‐gestational‐age (AGA) fetuses during hypoxia, in diabetic and non‐diabetic mothers. Material and methods A total of 17 358 validated paired arterial and ve
Osteoporosis often leads to fragility fractures of the hip, resulting in impaired quality of life and increased mortality. Augmenting the proximal femur could be an attractive option for prevention of fracture or fixation device failure. We describe a tissue engineering based strategy to enhance long-term bone formation in the femoral neck of osteoporotic rats by locally delivering bioactive molec
