We present a comparative study of xanthorhodopsin, a proton pump with the carotenoid salinixanthin serving as an antenna, and the closely related bacteriorhodopsin. Upon excitation of retinal, xanthorhodopsin exhibits a wavy transient absorption pattern in the region between 470 and 540 nm. We interpret this signal as due to electrochromic effect of the transient electric field of excited retinal
Nanostructured neural interfaces, comprising nanotubes or nanowires, have the potential to overcome the present hurdles of achieving stable communication with neuronal networks for long periods of time. This would have a strong impact on brain research. However, little information is available on the brain response to implanted high-aspect-ratio nanoparticles, which share morphological similaritie
Some colours might have different connotations depending on people’s cultural backgrounds. When talking about evacuation, the colour employed for exit signs and flashing lights plays a significant role because it is responsible for conveying a message to the evacuees, either danger or safety. The aims of this study are to evaluate the influence of red and green emergency way-finding systems on the
Popular Abstract in Swedish Dekompressionssjuka (DCS) är ett tillstånd som kan uppkomma när man utsätts för en hastig sänkning av omgivningstrycket. Bakgrunden till tillståndet är att vävnadslagrad gas frisätts till blodbanan och där på olika sätt kan ge upphov till symptom från lätta hudbesvär till livshotande påverkan på det centrala nervsystemet. Vid atmosfärstryck är gasinnehållet i kroppens vReductions in ambient pressure liberates gas in various tissues and can result in decompression illness. In this thesis the patophysiological implications of a blood gas interface resulting from decompression was investigated with reference to the influence on biochemical mediators of inflammation. In a series of experiments, animals and human subjects have been exposed to hyperbaric trauma of dif
Competition among phytoplankton for limiting resources may involve direct or indirect interactions. A direct interaction of competitors is the release of chemicals that inhibit other species, a process known as allelopathy. Here, we investigated the allelopathic effect of three toxic microalgae species (Alexandrium tamarense, Karenia mikimotoi and Chrysochromulina polylepis) on a natural populatio
Background: Surgical trauma evokes a systemic cytokine response which is enhanced in patients with colorectal cancer. The aim of this study was to locate the origin of the systemic cytokine response to colorectal surgery. Methods: The concentrations of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) were analysed in systemic and mesenteric venous blood in 12 patients operated on
The article is a response to a lecture held by Sarah Coakley at Lund University 2009. In relation to Coakley's reflections on pain, the article addresses the question whether the Passion story still today, and not only in an ecclesial context, can serve as an incitement to a kind of self-examinating reflection. In other words, is it possible to retrieve through the Passion a narrative framework wh
Recurrent ear infection in children during pre-school years is an important public health problem. Common advice given to parents is to minimize exposure of susceptible children to crowding and air pollution. This study aimed at investigating what changes parents undertake to improve the health of an otitis-prone child. Parents of children with 5 events before age thirty months (index children; n
Ubiquitination is a post-translational modification process that has a very important role in the homeostasis of eukaryotic cells. Linkage-specific ubiquitination determines the final destination of modified protein. Ubiquitination has also been reported to regulate inflammasome function and IL-1β degradation. Secretion of IL-1β by macrophages in response to inflammasome activation is a key proces
Plant-soil feedback is increasingly recognized as a vital framework to analyze multi-trophic interactions involving herbivores, plants and microbes, but research is still lacking on understanding such feedback in the context of global change. In grasslands, patterns of herbivory are expected to be affected by global change, further modifying existing plant-soil feedbacks. We tested this by evaluat
Permafrost contains about 50% of the global soil carbon. It is thought that the thawing of permafrost can lead to a loss of soil carbon in the form of methane and carbon dioxide emissions. The magnitude of the resulting positive climate feedback of such greenhouse gas emissions is still unknown and may to a large extent depend on the poorly understood role of microbial community composition in reg
Background: The SYNAPSE study (NCT03085797) demonstrated that mepolizumab decreased nasal polyp (NP) size and nasal obstruction in patients with chronic rhinosinusitis with NP (CRSwNP). Methods: SYNAPSE, a randomized, double-blind study, included patients with recurrent, refractory, severe CRSwNP, eligible for repeated surgery despite receiving standard of care (SoC). Patients received 4-weekly me
Dune slacks are biodiverse seasonal wetlands within sand dune systems, strongly influenced by the dynamics of the local groundwater regime. Future climate predictions indicate strong adverse impact on the hydrology and therefore ecology of these wetland ecosystems. In this study we aimed to find the most appropriate hydrological and ecological indicators to summarise dune slack plant community res
