Background: The mechanisms underlying high-frequency QRS components (HF-QRS) are incompletely understood. One theory is that HF-QRS are related to the conduction velocity of the heart. The purpose was to test this hypothesis by comparing HF-QRS in patients with left or right bundle branch block (LBBB and RBBB, respectively) to those in healthy subjects and in patients with ischemic heart disease (
The oxo-sulfido functional group cis-MoVIOS is essential to the activity of the xanthine oxidase family of enzymes but has proven elusive to synthesis in molecules containing no other four-electron ligands. A direct route to molecules containing this group has been achieved. The reaction system [MoO2(OSiPh3)2]/L in dichloromethane yields the complexes [MoVIO2(OSiPh3)2L] (L = phen (1), Me4phen (2),
We developed a clinical score to monitor tuberculosis patients in treatment and to assess clinical outcome. We used the WHO clinical manual to choose signs and symptoms, including cough, haemoptysis, dyspnoea, chest pain, night sweating, anaemia, tachycardia, lung-auscultation finding, fever, low body-mass index, low mid-upper arm circumference giving patients a TBscore from 0 to 13. We validated
To study whether antibodies to glutamic acid decarboxylase (GADab) are associated with subclinical beta-cell damage and impaired insulin secretion, we screened 441 nondiabetic patients with autoimmune thyroiditis (AT) for GADab, and 15 (3.4%) were found positive. Antibodies to IA-2 were found in two GADab+ and one GADab- patients. We matched 11 GADab+ and 13 GADab- AT patients who were euthyroid o
Malignant brain tumors present a major therapeutic challenge because no selective or efficient treatment is available. Here, we demonstrate that intratumoral administration of human α-lactalbumin made lethal to tumor cells (HAMLET) prolongs survival in a human glioblastoma (GBM) xenograft model, by selective induction of tumor cell apoptosis. HAMLET is a protein-lipid complex that is formed from α
D. Briihl and A. W. Inhoff (1995) found that exterior letter pairs showed no privileged status in reading when letter pairs were presented as parafoveal primes. However, T. R. Jordan, S. M. Thomas, G. R. Patching, and K. C. Scott-Brown (2003) used a paradigm that (a) allowed letter pairs to exert influence at any point in the reading process, (b) overcame problems with the stimulus manipulations u
The aim of this study was (1) to evaluate the effects of long-term oxygen treatment (LTOT) in elderly patients with severe exacerbations of chronic obstructive pulmonary disease (COPD) and hypoxaemia, (2) to study the health-related quality of life (QOL) during hospital stay and at follow-up, (3) to study the safety of an oxygen withdrawal test performed a few days after admission to hospital and
OBJECTIVE: The nitric oxide synthase inhibitor L-N(G)-methylarginine hydrochloride (L-NMMA HC1 546C88) causes reductions in cardiac output (CO), a potential limitation to clinical application. This drop in CO exceeds that from phenylephrine at matched systemic arterial pressure. We tested the hypothesis that the greater fall in CO attributable to L-NMMA primarily reflects a difference in venoconst
To develop more sensitive measures of impaired cardiac function in patients with pulmonary hypertension (PH), since detection of impaired right ventricular (RV) function is important in these patients. With the hypothesis that a change in septal function in patients with PH is associated with altered longitudinal and lateral function of both ventricles, as a compensatory mechanism, we quantified t
Objective: Generic substitution has contributed to economic savings but switching products may affect patient adherence, particularly among those using multiple medications. The aim was to analyse if use of multiple medications influenced the association between switching products and refill adherence to angiotensin-converting-enzyme (ACE) inhibitors in Sweden. Study Design and Setting: New users
Background and aims: The oxidation of low-density lipoprotein (LDL) cholesterol particles is an early atherogeninic event. Obese pediatric populations have higher levels of oxidized LDL (oxLDL) than normal weight children. The aim of this study was to evaluate the effect of a weight loss program on the biochemical profile and oxLDL levels in Spanish obese children and adolescents. Methods: Forty o
Background: Oat prolamin (avenin) is a family of proteins that contain several polymorphic components. The highinterspecific variability of avenin among cultivars, electrophoretic patterns have been used for grain protein comparisonand species relationships. Therefore, the present study was carried out to evaluate the effect of environment onavenin constitution following an effort to increase prot
Risk factors of stroke/thromboembolism (TE) and major bleeding, and incidence of these events in specific age categories in warfarin-treated patients with mechanical heart valves (MHV) are uncertain. Our objective was to calculate event rates in specific age categories and identify risk factors for adverse events. Methods and results We identified 4,810 treatment periods with MHV between January 2
My first encounter with a begging person led me to spend five years investigating the new situation regarding begging and giving in Sweden. The premise is that every-day actions and reactions to another person can be made visible through aesthetics with ethical underpinnings. My investigation takes place mainly in the urban landscape and in the media. The images always constitute the point of depa
The aim of this study is to understand the mechanisms behind the diffusion of fired bricks in Hellenistic Europe, initiated in the north Aegean in the 4th century BC. To this end, a social diffusion model is used to simulate the available archaeological data pertaining to this process. The starting point in the construction of the model is the assumption that different categories of people contrib
Objective: The authors sought to clarify the relationship between marriage and risk for alcohol use disorder. Method: The association between marital status and risk for first registration for alcohol use disorder in medical, criminal, and pharmacy registries was assessed in a population-based Swedish cohort (N=3,220,628) using longitudinal timedependent survival and co-relative designs. Results:
Background Children and adolescents with autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) are more likely to be surrounded by different risk factors. In order to work preventively with decreasing ADHD and ASD symptoms, there is a need of more knowledge concerning risk factors. Objective This study aimed to investigate school, health, lifestyle and social interactio
