Fluorescent probes based on photoinduced electron transfer (PET) quenching of long lifetime triangulenium fluorophores have found multiple applications. For such probes a successful design relies on the right balance between the rate of PET quenching and fluorescence. In a series of ADOTA (A) and DAOTA (D) triangulenium fluorophores appended with aniline-like quencher moieties, we have investigate

OBJECTIVE: The time taken to reach maximal haemostatic effect following local anaesthesia with epinephrine is generally believed to be <10 min. This is based on clinical experience and indirect measurements of perfusion using methods such as laser Doppler flowmetry and oxygen spectroscopy. However, the only study in which bleeding has been measured quantitatively in an intra-operative setting in h

Background Previous studies have indicated that vitamin K deficiency is common in non-bleeding critically ill patients with slightly prolonged prothrombin time-international normalized ratio (PT-INR). It has never been investigated thoroughly whether the administration of vitamin K to these patients could affect their PT-INR. Therefore, the aim of this registry study was to evaluate changes in PT-

Popular Abstract in Swedish Transplantation av nervvävnad till hjärnan är inte en ny idé. Redan 1890, publiserade Thompson de första försöken att transplantera vuxen hjärnvävnad till det vuxna centrala nervsystemet och han rapporterade att vävnaden överlevde i sju veckor "without wholly losing its identity". Trots detta var det först under 1970-talet som metoderna för intracerebral nervcellstranspIntracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. We have investigated the feasibli

Suicide in children and young adults is a leading cause of premature mortality, and there is a need to develop a more profound understanding of the factors that contribute to these deaths. This study is part of the nationwide Retrospective Investigation of Health Care Utilization in Individuals who died by Suicide in Sweden 2015, conducted at Lund University, Sweden. The aim was to examine symptom

Bone morphogenetic proteins (BMPs) are expressed and secreted during fracture repair. Although they are likely to be required for this process, little is known about their physiological role in bone regeneration. Noggin is a protein that specifically binds and inactivates several BMPs, It plays fundamental roles during early embryonal development and limb morphogenesis by this BMP-inactivating act
