Chebyshev polynomial techniques for solution of singular integral equations leading to square root singularities at the ends of the interval of integration are studied. It is shown that the results are less accurate when a singularity, albeit a weak one, appears between the interval ends. Typical examples are problems involving kinked cracks. Some attempts to improve the accuracy are discussed.
Many reports on living kidney donation describe rapid recovery. In our experience rehabilitation is rather slow. This study aimed to explore self-reported health status among living donors (LDs) three to four weeks and six months post-donation with a longitudinal design. In this study. LDs (n = 112) reported their physical and mental health by responding to a questionnaire before surgery, after th
BACKGROUND: The incidence of acute cardiovascular and cerebrovascular events in patients treated for complicated or uncomplicated peptic ulcer disease (PUD) has not been ascertained completely. METHOD: All patients with in-hospital treatment due to PUD between 1987 and 2007, who did not have any past history of acute or chronic cardiovascular or cerebrovascular disease, were identified through the
Treatment with docetaxel is the standard of care as first line chemotherapy in castration resistant prostate cancer. Due to serious side effects from the commercially available Taxotere formulation, we aimed to develop a safe and effective nanoparticle formulation of docetaxel. Liquid crystal nanoparticles (LCNPs), based on phosphatidyl choline, glycerol dioleate and polysorbate 80 dispersed in ex
In the adult mammalian brain, neurogenesis from neural stem/progenitor cells continues in two regions: the subgranular zone in the dentate gyrus and the subventricular zone lining the lateral ventricles. The generated neuroblasts migrate to their appropriate location and differentiate to mature granule cells and olfactory bulb interneurons, respectively. Following injury such as stroke, neuroblast
INTRODUCTION: Hyperactivity of the hypothalamic-pituitary-adrenal (HPA)-axis is a common finding in major depressive disorder. Similar studies on suicide attempters are less abundant, and the results are divergent. The main aim of the present study was to investigate HPA-axis parameters by the time of a suicide attempt and at follow-up in search for associations between HPA-axis function and suici
OBJECTIVES: The purpose of this study was to assess the effect of persistent organochlorine compounds through the dietary intake of fatty fish from the Baltic Sea on human fertility. METHODS: Information on time to pregnancy, subfertility, and infertility was collected retrospectively by self-administered questionnaires in 2 cohorts of fishermen's wives from the Swedish east (by the Baltic Sea) an
OBJECTIVES: To investigate changes in the knee during the first year after acute rupture of the anterior cruciate ligament (ACL) of volumes of joint fluid (JF), bone marrow lesions (BMLs), and cartilage volume (VC), and cartilage thickness (ThCcAB) and cartilage surface area (AC). To identify factors associated with these changes. METHODS: Fifty-eight subjects (mean age 26 years, 16 women) with an
PURPOSE: This study was conducted to examine the effects of 5-HT on extracellular signal-regulated kinase 1/2 (Erk1/2) and Akt pathways in prostate cancer (PC) cells. METHODS: PC cell lines PC-3, Du145, and LNCaP stimulated with 5-HT in the presence of MEK or PI3K inhibitors and 5-HT receptor subtype 1A antagonist were analyzed by Western blotting and immunofluorescence. The proliferation assay Br
The pandemic of type 2 diabetes is threatening the entire world population. The number of obese people in the world has quadrupled over the last 30 years. It is clear that the human genome has not undergone such a rapid change, and thus alone does not explain the increased obesity. In fact, the rapidly changing society seems to be on a collision course with the genome. Through gene research we may
The post-translational modification of different proteins via direct ubiquitin attachment is important for various cellular processes. Dysregulation of components of the ubiqutin system have been linked to many diseases including cancer. CYLD is a deubiquitination enzyme that can cleave the lysine 63-linked polyubiquitin chains from target proteins and regulate cell survival or cell proliferation.
Maximum oxygen uptake ([Vdot]O(2PEAK)) is generally considered to be the best single marker for aerobic fitness. While a positive relationship between daily physical activity and aerobic fitness has been established in adults, the relationship appears less clear in children and adolescents. The purpose of this paper is to summarise recently published data on the relationship between daily physical
Aims In atrial fibrillation (AF), a relation between electrocardiogram (ECG) parameters such as fibrillatory wave amplitude and stroke has been sought with conflicting results. In this study, we tested the hypothesis that the atrial fibrillatory rate of surface ECG lead V1 is related to stroke risk and may consequently be helpful for identifying high-risk patients. Methods and results Atrial fibri
PURPOSE: Accumulation of oxidized LDL in the arterial wall is believed to play a key role in the development of atherosclerosis. Experimental studies have identified the presence of immune responses against epitopes in oxidized LDL that protects against atherosclerosis. We have produced human recombinant IgG against one of these epitopes (aldehyde-modified apoB-100 amino acids 661-680) and demonst
Objective. This study compares laparoscopic and percutaneous endoscopic gastrostomy (PEG) in a paediatric population to test the hypothesis that there is a difference in the frequency of serious gastrointestinal complications between the two methods. Methods. All reports published between 1995 and 2009 on laparoscopic gastrostomy and PEG in children was included. Prospective and retrospective tria
Vascular smooth muscle cell (VSMC) migration and proliferation are critical events in vascular proliferative diseases. Recent studies have established micro-RNAs (miRNAs) as important mediators for the modulation of VSMC phenotype by targeting transcription factors and the cytoskeleton, which act as molecular switches for VSMC differentiation. The importance of miRNAs for VSMC development, differe
