The objective of this study was to probe the molecular mechanisms underlying the increase in sensitivity of cells to bradykinin (BK) following expression of a transforming Ha-ras oncogene. We used native NIH3T3 fibroblast (3T3) cells and 3T3 cells transfected with a glucocorticoid-sensitive oncogenic Ha-ras construct (DT cells). DT cells incubated in the presence of 1 μM dexamethasone (DEX) for 24
Chemical cross-linking combined with site-directed mutagenesis was used to evaluate the role of extracellular cysteines and their positions relative to the binding site for the agonist bradykinin (BK) in the human BK B2 receptor. All extracellular cysteines, Cys20, Cys103, Cys184, and Cys277, in the receptor were mutated to serines, and single and double mutants were transfected into COS-7 cells.
We have previously shown that exposure of DDT1 MF-2 smooth muscle cells to the agonist bradykinin (BK) resuits in a rapid B2 kinin receptor-mediated internalization of BK followed by degradation of the intracellular BK [Munoz, C. M., and Leeb-Lundberg, L. M. F. (1992) J. Biol. Chem. 267, 303-309]. Here, we show that BK internalization is paralleled by sequestration of the occupied B2 receptors. Se
Purpose: To demonstrate the feasibility of multidimensional diffusion MRI to probe and quantify microscopic fractional anisotropy (µFA) in human kidneys in vivo. Methods: Linear tensor encoded (LTE) and spherical tensor encoded (STE) renal diffusion MRI scans were performed in 10 healthy volunteers. Respiratory triggering and image registration were used to minimize motion artefacts during the acq
Background: Cardiac rehabilitation improves prognosis after an acute myocardial infarction (AMI), however, the optimal method of implementation is unknown. The aim of the study was to evaluate the effect of individually-tailored, nurse-led cardiac rehabilitation on patient outcomes. Method: This single-centre retrospective observational study included 217 patients (62±9years, 73% men). All patient
Background: The dual antiplatelet therapy (DAPT) score guides decisions on DAPT duration after coronary stenting by simultaneously predicting ischemic and bleeding risk. Objectives: This study sought to assess the performance of the DAPT score in a nationwide real-world population. Methods: The study used register data in Sweden (2006 to 2014) and followed 41,101 patients who had undergone 12 mont
Bile acids (BAs) act as signaling molecules in various physiological processes, and are related to colonic microbiota composition as well as to different types of dietary fat and fiber. This study investigated whether guar gum and pectin-two fibers with distinct functional characteristics-affect BA profiles, microbiota composition, and gut metabolites in rats. Low- (LM) or high-methoxylated (HM) p
This work is the result of an interest in realizing a study about the difficulties that Swedish students encounter when learning Spanish as a foreign language, levels A2, B1 and B2, when choosing between the tenses the imperfect and the preterit in state verbs and achievement verbs. To obtain material for this study, three different tasks were used. In the first one, the students received a story
Objective: The aim of this study was to assess the risk of serious adverse effects after radiotherapy (RT) with curative intention and radical prostatectomy (RP). Materials and methods: Men who were diagnosed with prostate cancer between 1997 and 2012 and underwent curative treatment were selected from the Prostate Cancer data Base Sweden. For each included man, five prostate cancer-free controls,
Providing equal access to health care is an important objective in most health care systems. It is especially pertinent in systems like the Swedish primary care market, where providers are free to establish themselves in any part of the country. To improve equity in access to care, 15 out 21 county councils in Sweden have implemented risk-adjusted capitation based on the Care Need Index, which inc
Purpose: There is currently no molecular signature in clinical use for adjuvant endocrine therapy omission in breast cancer. Given the unique trial design of SweBCG91-RT, where adjuvant endocrine and chemotherapy were largely unadministered, we sought to evaluate the potential of transcriptomic profiling for identifying patients who may be spared adjuvant endocrine therapy. Experimental Design: We
Background Long-chain polyunsaturated fatty acid (LCPUFA) especially the n-3-FA of skeletal muscle phospholipids may facilitate insulin action, whereas saturated and trans-FA act oppositely. Community studies show that non-diabetic weight matched obese men and women display similar insulin resistance, despite the fact that an android fat distribution is detrimental to insulin action. The increased
BACKGROUND: Use of a catheter-free, radio telemetric, oesophageal pH-monitoring system in paediatric clinical practice allows patients to follow a more normal physiological pattern of activities and causes less discomfort. At our institution, placement of the capsule is done under general anaesthesia, which restricts the child's activity during the first day. The aim of this study was to determine
OBJECTIVE: To study fat metabolism and evaluate lipid deposition in hepatocytes and Kupffer cells during parenteral nutrition (PN) with or without fat. DESIGN: 20 male Sprague-Dawley rats, divided into four groups, were investigated. Rats fed orally were used as a reference group and compared to three groups of rats receiving PN either without fat or with 33% of non-protein energy as fat or with 6
Background. Describing the illness-story from a patient perspective could increase understanding of living with a chronic disease for health professionals and others, facilitate decision-making about treatment and enhance information about the outcome from a patient perspective. Aim. To illuminate patients' illness experiences of having a gastro-oesophageal reflux disease (GORD), going through sur
Background and Purpose: The 'capsular warning syndrome' (CWS) of recurrent stereotyped episodes of motor or sensory dysfunction is clinically well recognized, and is associated with a high risk of imminent lacunar infarction with permanent deficits resembling those of CWS. However, the pathophysiology of CWS has not been well characterized. We report a clinicoanatomic correlation with MR imaging s
Horses have a great social, cultural and economic importance in society and contribute to the open landscape. There are currently more than 360,000 horses in Sweden, which together produce over 2.7 million tons of manure per year. This represents 10% of the total amount of manure from all livestock in the country. Most horses are found in urban or near-urban rural areas, which means that there is
Filmdistributionen befinner sig i en ny digital verklighet. Den snabba tekniska utveckling som har ägt rum de senaste decennierna har inneburit stora utmaningar för såväl filmindustrins affärsmodell som de upphovsrättsliga bestämmelser som reglerar skyddet för filmverk och dess upphovsmän. Ett exempel på en bestämmelse vars tillämpningsområde är oklart till följd av den nya distributionen av digitFilm distribution has found itself in a new digital reality. The swift progress of technology that has taken place during the past decades has posed major challenges for both the film industry's business model and for the copyright laws that regulate the area. An example of a regulation whose scope is unclear as a result of the new distribution of digital copies is the principle of exhaustion.
Sammanfattning En stor del av svensk handel går ut på att distribuera och sälja varor. Ett företag kan välja att distribuera varor självt, alternativt ingå samarbete med annan part. För en part som funderar på att distribuera varor genom samarbete finns det många alternativ att välja på och följaktligen måste en part fundera över och ta ställning till olika för- och nackdelar, exempelvis vilken koSummary A significant part of Swedish trade involves distributing and selling goods. A company may choose to manage distribution of goods by himself or enter a partnership. A party who consider distribute goods through cooperation must count on various factors, such as desired control of the various market-ing stages, own and the other party resources, conditions in the specific market and risk sh
