We studied if bladder cancers respond to HAMLET (human alpha-lactalburnin made lethal to tumor cells) to establish if intravesical HAMLET application might be used to selectively remove cancer cells in vivo. Patients with nonmuscle invasive transitional cell carcinomas were included. Nine patients received 5 daily intravesical instillations of HAMLET (25 mg/ml) during the week before scheduled sur

Objective: GH causes insulin resistance, impairs glycemic control and increases the risk of vascular diabetic complications. Sulphonylureas stimulate GH secretion and this study was undertaken to investigate the possible stimulatory effect of repaglinide and nateglinide, two novel oral glucose regulators, on critical steps of the stimulus-secretion coupling in single rat somatotrophs. Methods: Pat

By emphasising the involvement of elderly people in a project applying a mixed-method approach, the overriding objective of this study was to identify and prioritise concrete measures aimed at increasing accessibility and safety in the outdoor pedestrian environment within a residential area of a Swedish town. Measures generally given priority were: the separation of pedestrians/cyclists, lower sp

Mercury and selenium in whole blood and serum of 245 17-year old Swedish adolescents were analysed. The relationships between these elements' concentrations and the consumption of fish as well as the number of dental amalgam fillings were studied. The geometric means (GM) of the mercury concentrations were 1.1 mug/L in blood and 0.43 mug/L in serum. The mean selenium concentration in blood was 110

Ball rolling in dung beetles is thought to have evolved as a means to escape intense inter- and intra-specific competition at the dung pile. Accordingly, dung beetles typically roll along a straight-line path away from the pile, this being the most effective escape strategy for transporting dung to a suitable burial site. In this study, we investigate how individual diurnal dung beetles, Scarabaeu

Recent research suggests that multilingual students tend to use their complete language repertoires, particularly their L1, when writing in a non-native language (e.g. Cenoz & Gorter 2011; Wang 2003). While there is some international research on the L2 and L3 writing process among bilinguals, the L2/L3writing process of bilingual and multilingual individuals in the Swedish context remains une

In 2012 a Swedish project was initiated to study and document the archaeological remains at Gebel el Silsila, located about 65 km north of Aswan and 130 km south of Luxor. Mission director Dr. Maria Nilsson of Lund University summarizes the results of the first three seasons.

Studies of epithelial cancers (i.e., carcinomas) traditionally focused on transformation of the epithelium (i.e., the cancer cells) and how aberrant signaling within the cancer cells modulates the surrounding tissue of origin. In more recent decades, the normal cells, blood vessels, molecules, and extracellular components that surround the tumor cells, collectively known as the "tumor microenviron

Background: Positive intersexual genetic correlations are typically viewed as constraining the evolution of sexual dimorphism, when traits are subject to sexually antagonistic selection. Our study species, the damselfly Ischnura elegans, has a female-limited colour polymorphism with three female colour morphs (males are monomorphic), one of which is considered to be a male mimic. Questions: Are th

Objectives This study was designed to compare vascular contractile and relaxing responses to G-protein coupled receptor agonists among the different regions of arteries following heat stress in rats. Methods Heat exposure was performed by increasing the internal temperature of the rats to 42 degrees C for 15 min. After heat stress for 48 h, a rnyograph system was used to monitor the contractile re

Objective. To investigate the effects of prostate-specific antigen (PSA) testing of men without clinical signs of prostate cancer on the incidence of prostate cancer in Sweden. Material and methods. Information on the cause of diagnosis, tumour characteristics and primary treatment for patients diagnosed with prostate cancer between January 1999 and December 2007 was extracted from the National Pr

The aim of this myocardial perfusion imaging (MPI) study was to compare the diagnostic performance of two computer-aided diagnosis (CAD) systems, EXINI Heart(TM) (EXINI), and PERFEXTM (PERFEX) Emory Cardiac Toolbox (ECT), and the summed stress score (SSS) values from both software packages. We studied 1,052 consecutive patients who underwent 2-day stress/rest Tc-99m-sestamibi MPI studies. The refe

Background: A beneficial role of fish consumption on the risk of myocardial infarction (MI) has been reported and is mostly ascribed to n-3 (omega-3) fatty acids. However, fish also contains methylmercury, which may increase the risk of MI. Objective: The objective was to determine how fish consumption and erythrocyte concentrations of mercury (Ery-Hg) and selenium (Ery-Se) are related to the risk

Long-term studies of outcome after stroke are scarce. Our aim was to study functional status and patient-reported outcome 10 years after a first-ever stroke.Ten-year follow-up was conducted among the survivors from a population-based group of 416 patients included in the Lund Stroke Register, Sweden, between March 1, 2001, and February 28, 2002. The Barthel index was used to assess the functional

The abundant serine proteinase inhibitor heparin cofactor II (HCII) has been proposed to inhibit extravascular thrombin. However, the exact physiological role of this plasma protein remains enigmatic. In this study, we demonstrate a previously unknown role for HCII in host defense. Proteolytic cleavage of the molecule induced a conformational change, thereby inducing endotoxin-binding and antimicr

The team behavior literature is ambiguous about the relations between members’ interpersonal processes—task debate and task conflict—and team performance. From a social influence perspective, we show why members’ interpersonal processes determine team performance over time in small groups. Together, over time, dissenting in-group minorities who share information (via debate) with majorities, who s
