Popular Abstract in Swedish Immunsystemet skyddar kroppen mot infektion. För att kunna skydda mot infektion krävs att immunsystemet är utrustat med kraftfulla biokemiska motmedel. Ett sådant motmedel är antikroppar. Antikroppar är proteiner som känner igen och specifikt binder till andra molekyler via en s k molekylbindande klyfta. När antikropparna har bundit in till en molekyl på t ex en bakteriPrimary infections and vaccination stimulates the immunesystem to produce memory cells that rapidly respond to reexposure of the same antigen. These memory responses are dependent on an adaptive type of immunity that sustains the reactivity of the immune system by long-lived memory immune cells. From an evolutionary perspective adaptive immunity as such appears to be restricted to jawed vertebrate

Popular Abstract in Swedish Äggstockscystors förekomst, risken för kvinnor med cystor att utveckla äggstockscancer samt Plasminogenaktiveringssystemets uttryck i äggstockstumörer Äggstockscancer är ovanligt hos unga kvinnor, men den 4:e vanligaste dödsorsaken i cancer hos kvinnor i åldern 45-64 år i Sverige. Livstidsrisken är 1 på 70. På grund av få eller obefintliga symptom upptäcks äggstockscanThe aims were to assess the prevalence of ovarian tumors in fertile asymptomatic women and to evaluate the risk of ovarian cancer in women with a history of benign ovarian tumors and endometriosis. In order to search for biomarkers in ovarian tumors, the plasminogen activating (PA) system was studied. A random sample of women 25-40 years old was invited to a transvaginal ultrasonography examinati

This paper raises the issues confronting the minority cohort’s participation in the construction industry. Women in construction are seen as the wrong gender to be around for the construction occupations require not only manual dexterity but physical strength. Currently, the industry is employing less than 10% of the female in the workforce with even lower participation in crafts and trade. This p

Popular Abstract in Swedish Pappersbrott i planet har studerats med hjälp av den kohesiva sprick modellen ur ett experimentellt såväl som ur ett teoretiskt perspektiv. Brott i en pappersremsa erhålls när remsan i en provmaskin belastas till sin maximala bärlast. Om remsan är tillräckligt kort fås en stabil nedåtgående last-förlängnigs kurva efter det att max lasten är nådd. Det visade sig att denThe in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone

This book contains a series of articles based on papers presented at a Nordic symposium held in autumn 1997. The articles have archaeological material culture as their main focus. They deal with the fundamental, but often ignored, questions of how form, function and context relate to each other and how form and in particular function may change with context. The central concept of context - define

The short paper describes and exemplifeis specific design and research considerations in developing efficient and engaging pedagogical agents that not only capitalize on technological advancements but are also sensitive to cognitive, emotional, and social aspects while valuing and maintaining ecological validity in an educational context

Prostate-specific antigen (PSA) is a glycoprotein produced by the prostate gland. It occurs in several molecular forms in the blood and assays have been developed to measure free PSA and PSA in complex with alpha-1-antichymotrypsin (PSA-ACT). Higher proportions of free PSA (PSA-F/T) in blood are found in subjects with benign prostatic hyperplasia (BPH) as compared to cancer patients. Utilizing imm

The physics program in Hall A at Jefferson Lab commenced in the summer of 1997 with a detailed investigation of the 16O(e,ep) reaction in quasielastic, constant (q,) kinematics at Q20.8 (GeV/c)2, q1 GeV/c, and 445 MeV. Use of a self-calibrating, self-normalizing, thin-film waterfall target enabled a systematically rigorous measurement. Five-fold differential cross-section data for the removal of p

About the concept of pain in a literary context.

To be able to explore different signal types and processing techniques, apt for sediment mapping, programmable, fully digital profiling systems has been built and tested. The systema are designed to be deployed also at small water depths from small boats, without special handling equipment. The usable frequency band is 100-25000 Hz, limited to approximately 2-10 kHz depending on the projector used

Popular Abstract in Swedish Melatonin är ett hormon som produceras i, och frisätts från pinealorganet hos ryggradsdjur. Melatoninets viktigaste uppgift är att till hjärnan förmedla signalen om nattens längd, d.v.s vilken årstid det är. Produktionen och frisläppningen sker rytmiskt med den högsta nivån under natten. Melatoninet transporteras ut i kroppen via blodet och binder till särskilda mottagaMelatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. It has previously been suggested that functional interaction exists between central binding sites for GABA/benzodiazepines (GABAA/bzd receptors) and melatonin in the central nervous system, and that GABA a
