Mass spectrometry was used to determine the endotoxin (lipopolysaccharide, LPS) marker 3-hydroxytetradecanoic acid and 3-deoxy -D-manno-2-octulosonic acid in cigarette tobacco and smoke particles. Tobacco from cigarettes of different brands purchased in four different countries in Europe and Asia contained similar amounts of LPS. Indoor exposure to environmental tobacco smoke (ETS) in rooms of smo

Popular Abstract in Swedish Vid diabetes råder en oförmåga att hålla nere blodsockret, i synnerhet efter en måltid. Under normala förhållanden orsakar en höjning av blodsockret att insulinfrisättningen stimuleras. Insulin ökar upptaget av glukos i vävnaderna i kroppen, vilket sänker blodsockret. Under vissa förhållanden, såsom fetma, minskar effekten av insulin, ett fenomen som även kallas insulinThe parasympathetic nerves are important for the regulation of insulin secretion, in particular after meal intake. Apart from acetylcholine, several neuropeptides can be found in the parasympathetic nerves innervating the islets of Langerhans, including gastrin-releasing peptide (GRP) and pituitary adenylate cyclase activating polypeptide (PACAP). Exogenous administration of either GRP or PACAP ha

Popular Abstract in Swedish Effekter av giftiga växtplankton på copepoder Vad är växtplankton och copepoder? Växtplankton eller mikroalger som de också kalla's är de dominerande växterna i havet. Det finn's många olika typer av växtplankton och de är alla mycket små (dera's storlek är mellan ett par till några hundra tusendelar av en millimeter). Växtplanktonen använder ljusenergin från solen ocPhytoplankton growth and loss rates are governed by several factors and in many cases, when growth control fails, algal blooms are established. Such blooms can be formed by different phytoplankton species and some of them have harmful impacts on marine ecosystems. One of these negative impacts by some bloom-forming phytoplankton is the ability to produce toxic or inhibitory compounds with broad ef

Popular Abstract in Swedish Den medicinska termen sepsis, "blodförgiftning" orsakas av bakterier i blodet. Symptombilden kan variera från tämligen lindriga förlopp till septisk shock, som har en hög dödlighet. Vid sepsis och septisk shock aktiveras olika kroppsegna system såsom koagulations- och komplementsystemet. Många mekanismer medieras av så kallade cytokiner. Dessa budbärarmolekyler byggs upPurified bacterial cell wall components peptidoglycan and teichoic acid were isolated from staphylococcal species S. aureus and/or S. epidermidis and tested for their ability to induce cytokine release from plastic-adherent human monocytes. Both cell wall components dose-dependently induced TNF-alpha, interleukin-1beta, and interleukin-6 release, peptidoglycan being more potent than teichoic acid.

Every year, there are more than 2500 new international students coming to Lund University and starting their higher education path. A higher number of foreign students increased the international competitiveness of Lund University, but at the same time the international students had to face many problems for instance, culture shock and language barriers. In this report we focused on issues in teac

Scientific communication presumes a well functioning infor¬mation and documentation system. Information retrieval systems have been designed for making possible rapid and precise answers to inquiries. This report includes (1) a short survey of international and national documentation activities, (2) a description of rules and criteria to be used and the way these can be applied in an information r
