Radioimmunotherapy of Metastatic Disease - Studies of Alpha- and Beta-particle-Emitting Radionuclides in a Preclinical Model

Popular Abstract in Swedish Cancer behandlas i första hand med kirurgi, cellgifter och extern strålbehandling. Under senare år har man dessutom utvecklat så kallade målsökande behandlingar, som binder till en viss struktur i tumören. De kan verka på olika sätt: antingen genom att blockera en signal i cellerna och på så vis hindra tumören från att växa, eller genom att stimulera patientens immunförIn radioimmunotherapy, monoclonal antibodies (mAbs) are used as a targeting agent carrying a toxic payload consisting of radionuclides. This treatment allows the irradiation of small lesions, even on the microscopic level. In the present work, two radionuclides with different properties were used. Lutetium-177 (177Lu) is a beta-particle-emitting radionuclide (t½=6.7 days) and astatine-211 (211At)

The effect on dispersal from complex correlations in small-scale movement

Calculations of large-scale displacement distances were made to evaluate the combined effect of small-scale movement pattern of a Collembola, Protaphorura armata. The effect of presence of food and conspecific density on turning angle, step length and activity/motility was investigated. Calculations of net square displacement were made both by assuming correlated random walk (CRW) and by resamplin

Review of: C. L. Westphahl. A Discourse Analysis of the Letter to the Hebrews. The Relationship between Form and Meaning (Library of NT Studies, 297), T & T Clark Intern. London – New York. 339 pp

Westphal's thesis contains a summary of earlier structural analyses of Hebrews. Her own discourse analysis structures Hebrews into three parts 1) 1:1–4:16; 2) 4:11–7:28 and 8:1–10:25; 3) 10:19–13:25. Westphal characterizes Heb 4:11-16 and 10:19-25 as "overlapping" parts and as keys to the structure and meaning of Hebrews. The structure according to this approach is not new. A shortcoming in this t

Using Conceptual Spaces to Model Actions and Events

Actions and events are central to a semantics of natural language. In this article, we present a cognitively based model of these notions. After giving a general presentation of the theory of conceptual spaces, we explain how the analysis of perceptual concepts can be extended to actions and events. First, we argue that action space can be analyzed in the same way as, for example, colour space or

Altering the laccase functionality by in vivo assembly of mutant libraries with different mutational spectra

The generation of diversity for directed protein evolution experiments shows an important bottleneck in the in vitro random mutagenesis protocols. Most Of them are biased towards specific changes that eventually confer a predicted and conservative mutational spectrum, limiting the exploration of the vast protein space. The current work describes a simple methodology to in vivo recombine mutant lib

Specialized pediatric healthcare with limited resources: Surgery, anesthesia and oncology for children in low- and middle-income countries

Aim: This thesis serves two purposes. First, it informs specialists in global public health to consider a broader spectrum of pediatric disease. Second, it informs specialists in pediatric hospital care of how the feasibility of their clinical practice depends on a functioning health care system. Methods: The papers contextualize pediatric disease entities that so far have received relatively sp

Dynamic and Static Light Scattering Analysis of DNA Ejection from Phage λ

With the aid of time-resolved dynamic light scattering (DLS) and static light scattering (SLS), we have analyzed the ejection kinetics from the bacterial virus bacteriophage (or phage) lambda, triggered in vitro by its receptor. We have used DLS to investigate the kinetics in such a system. Furthermore, we have shown that both SLS and DLS can be interchangeably used to study the process of phage D

The stimulatory action of tolbutamide on Ca2+-dependent exocytosis in pancreatic beta cells is mediated by a 65-kDa mdr-like P-glycoprotein

Intracellular application of the sulfonylurea tolbutamide during whole-cell patch-clamp recordings stimulated exocytosis >5-fold when applied at a cytoplasmic Ca2+ concentration of 0.17 microM. This effect was not detectable in the complete absence of cytoplasmic Ca2+ and when exocytosis was elicited by guanosine 5'-O-(3-thiotriphosphate) (GTPgammaS). The stimulatory action could be antagonized by

Reduced hippocampal neurogenesis in R6/2 transgenic Huntington's disease mice.

We investigated whether cell proliferation and neurogenesis are altered in R6/2 transgenic Huntington's disease mice. Using bromodeoxyuridine (BrdU), we found a progressive decrease in the number of proliferating cells in the dentate gyrus of R6/2 mice. This reduction was detected in pre-symptomatic mice, and by 11.5 weeks, R6/2 mice had 66% fewer newly born cells in the hippocampus. The results w

Psychosocial and geriatric correlates of functional status after total hip replacement

Objective. To determine whether psychosocial factors, chronic diseases, and common geriatric problems are associated with poor physical function 3 years after primary total hip replacement (THR). Methods. We studied a sample of Medicare recipients in Ohio, Pennsylvania, and Colorado (n = 922) who underwent primary THR in 1995 (mean +/- SD age 73.1 +/- 5.6 years, 32% men). Participants completed a

Relapsing polychondritis, induced in mice with matrilin 1, is an antibody- and complement-dependent disease

Relapsing polychondritis is an autoinumme disease that affects cartilage in the ear, nose, and respiratory tract. A pathogenic immune response has been proposed and antibodies to several cartilage proteins are detected in sera from these patients. To investigate the role of the humoral immune response in relapsing polychondritis, we used the matrilin-1-induced relapsing polychondritis model. Mice

Cartilage oligomeric matrix protein induction of chronic arthritis in mice.

OBJECTIVE: To develop a new mouse model for arthritis using cartilage oligomeric matrix protein (COMP) and to study the role of major histocompatibility complex (MHC) and Ncf1 genes in COMP-induced arthritis (COMPIA). METHODS: Native (pentameric) and denatured (monomeric) COMP purified from a rat chondrosarcoma was injected into mice with Freund's adjuvant to induce arthritis. C3H.NB, C3H.Q, B10.P

Increased thrombin generation in women with a history of preeclampsia

Introduction: Women with a history of preeclampsia have an increased risk for cardiovascular disease in later Life. We evaluated thrombogenic characteristics of women with a previous history of preeclampsia, expressed in levels of thrombin generation, number of micropartictes and related to menstrual cycle and endothelial function, measured as flow-mediated dilatation. Materials and methods: We in
