The biosynthesis of molecular species of phosphatidylethanolamine and phosphatidylcholine in isolated rat liver parenchymal cells was studied with [32P]phosphate and [3H]glycerol as precursors. Addition to the cells of albumin-bound oleic or linoleic acid resulted in the synthesis of high proportions of dioleoyl- or dilinoleoyl-phospholipids, especially from labeled glycerol. The fact that these s
It is proved that network realizability of controllers can be enforced without conservatism using convex constraints on the closed loop transfer function. Once a network realizable closed loop transfer matrix has been found, a corresponding controller can be implemented using a network structured version of Internal Model Control.
The hydrolysis of polyenoic fatty acid ester bonds with pure human colipase-dependent lipase, with carboxyl ester lipase (CEL) and with these enzymes in combination was studied, using [3H]arachidonic- and [14C]linoleic acid-labelled rat chylomicrons as a model substrate. During the hydrolysis with colipase-dependent lipase, the amount of 3H appearing in 1,2-X-diacylglycerol (DG) markedly exceeded
Avhandlingen består av tre oberoende kapitel som alla är empiriska studier av forskare och den roll som olika typer av rörlighet spelar för att forma forskarnas vetenskapliga produktion och karriär.Kapitel 1 studerar effekterna av avregleringen av svensk arbetsmigration, 2008, på publiceringsproduktiviteten hos akademiker verksamma i Sverige. Reformen ledde till en kraftig ökning av antalet asiatiThe thesis consists of three independent chapters. The chapters are all empirical studies of scientists and the role that different types of mobility play in shaping researchers' scientific output and careers.Chapter 1, uses the liberalization of Swedish work migration, in 2008, to study the effect of immigration on the publishing productivity of incumbent academics in Sweden. The reform led to a
Background: The aim of this study is to evaluate the impact of lymphovascular space invasion (LVSI) on the risk of lymph node metastases and survival in endometrioid endometrial adenocarcinoma. Material and methods: As regard the study design, this is a cohort study based on prospectively recorded data. Patients with endometrioid endometrial adenocarcinoma registered in the Swedish Quality Registr
BACKGROUND: Patients with platinum-sensitive recurrent ovarian cancer are a heterogeneous group, and it is not possible to accurately predict the progression-free survival (PFS) in these patients. We developed and validated a nomogram to help improve prediction of PFS in patients treated with platinum-based chemotherapy.METHODS: The nomogram was developed in a training cohort (n=955) from the CALY
For the study of prognostic factors, the medical researchers have access to a number of advanced statistical techniques available in standard program packages. A tradition has developed where survival or time to relapse is analysed on the basis of statistical materials with few patients but a large number of possible explanatory variables. In statistical "fishing expeditions" the p-values are used
A systematic review of chemotherapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for the evaluation of the scientific literature are described separately (Acta Oncol 2001; 40: 155-65). This overview on chemotherapy for epithelial ovarian cancer is based on a total of 176 scientific reports. Five meta-analyses incl
PURPOSE: Adjuvant chemotherapy versus observation and chemotherapy at progression was evaluated in 162 patients in a prospective randomized multicenter study. We also evaluated DNA-measurements as an additional prognostic factor.PATIENTS AND METHODS: Patients received adjuvant carboplatin AUC 7 every 28 days for six courses (n = 81) or no adjuvant treatment (n = 81). Eligibility included surgicall
This article examines the impact of prognostic factors, adjuvant therapy, and randomized trials on the overall survival of patients with endometrial cancer. The potential role of radiation therapy as an adjuvant therapy, as well as the role of lymph node dissection, in the treatment of endometrial carcinomas is reviewed.
