This questionnaire study was set up to assess the perceptions of risk factors for infusion phlebitis among Swedish nurses, as their concepts of these factors may influence the incidence. A majority of the nurses believed that insertion of a peripheral venous catheter in the forearm and catheter rotation within 48 hours was protective. These measures are not supported in recent studies and guidelin
The slope of the active distances is an important parameter when investigating the error-correcting capability of convolutional codes and the distance behavior of concatenated convolutional codes. The slope of the active distances is equal to the minimum average weight cycle in the state-transition diagram of the encoder. A general upper bound on the slope depending on the free distance of the con
The regioselectivity of the hydrosilylation of substituted 1,3-dienes catalysed by several rhodium complexes in the presence and absence of oxygen was studied. In addition to the already known accelerating effect, the presence of oxygen strongly affected the product distribution. For 2-substituted 1,3-dienes in the presence of oxygen the regioselectivity was in the range of 1 : 6 to 1 : 10 in favo
An experimental technique with which to measure the fracture stress of fused curd grains, submerged in ultrafiltered milk permeate, has been developed and applied to curd grains of rennet-induced skim milk at pH 6.40 during the first 25 min of fusion. Effects of applied compressive stress within the range of 25-50 Pa, syneresis time, fusion time and tension loading rate were investigated. Fracture
The purpose of this study was to determine the capacity of cells transduced with human beta-defensins (HBDs) to express antimicrobial peptides, since sufficient expression level is required for effective antimicrobial activity. Retroviral vector pBabeNeo and lentiviral vector SIN18cPPTRhMLV (SIN18) carrying HBDs were utilized to transduce non-HBD-expressing cells such as fibroblasts or HBD-produci
Popular Abstract in Swedish Det är välkänt att övervikt och fetma är starkt associerade med sjukliga förändringar i hjärtkärlsystemet och ökar risken att drabbas av hjärtkärlsjukdom och förtida död. Trots att viktnedgång hos överviktiga kan leda till en tillbakagång av sjukliga förändringar i hjärta och kärl, har man dock inte klart visat att viktnedgång leder till minskad risk att drabbas av hjärHigh body mass index (BMI) is associated with cardiovascular risk factors such as hypertension, dyslipidemia, and insulin resistance. Obesity is also an independent risk factor for coronary artery disease (CAD) and can cause structural as well as functional changes in the heart. High BMI is associated with increased mortality in the population. Weight-loss from a state of overweight or obesity may
BACKGROUND AND OBJECTIVES: Few studies have demonstrated that bacterial vaginosis (BV) is associated with sexual behavior risk factors similar to those for other sexually transmitted diseases. The objective of this study was to determine the prevalence of these factors in a multivariate analysis of data from women infected with BV and Chlamydia trachomatis, and noninfected control subjects. GOALS:
Recently, X-ray crystallographic evidence of quinoidal charge delocalization in poly-p-phenylene cation radicals was reported [Banerjee, M. et al., J. Am. Chem. Soc. 2007, 129, 8070]. In this paper, direct visual evidence for quinoidal charge delocalization in quaterphylene (QP) is shown with three-dimensional (31)) charge difference densities. It was revealed that the extra positive charge mainly
Objective To study, in a large cohort, the association between the use of anti-asthmatic drugs during pregnancy and pregnancy complications. Methods Using the Swedish Medical Birth Register, we identified 24,369 women who reported the use of anti-asthmatic drugs in early pregnancy and 7778 women who were prescribed such drugs later during pregnancy by antenatal care system centres, during the peri
Two different products of calcium magnesium acetate (CMA) were tested. Their molar ratios, View the MathML source, were 1.26 and 0.91 respectively. Both products were used as concentrated solutions. In addition, the 0.91 product was also used in a solution, which was diluted so that its freezing point depression was as great as that of a 3 percent (by mass) sodium chloride solution. — Prisms of 0.
In a study of 972 women, sexual characteristics of 66 women with a cervical human papillomavirus infection (CHPI) were compared to the remaining study population. Among a number of sexual variables that were significantly correlated with CHPI were number of lifetime sexual partners, short partnerships, many recent partners, infidelity, casual travel sex, sexual debut abroad, oral and anal sex, and
Ca2+ inflow via store-operated Ca2+ channels was investigated in rings of rat tail and basilar arteries kept in serum-free organ culture, which is known to preserve the contractility of the vascular smooth muscle. After culture for 3-4 days, Ca2+ release from intracellular stores in response to caffeine (20 mM) was augmented 2- to 4-fold. Following depletion of intracellular Ca2+ stores by caffein
Gel swelling experiments have been used to study the binding of ionic surfactants to a series of nonionic alkylacrylamide hydrogels of increasing hydrophobicity. The binding of hexadecyl trimethylammonium (C-16-TA(+)) to uncharged gels is sensitive to both the hydrophobicity of the gel and the counterion to the surfactant. There is a minimum hydrophobicity threshold below which binding of the surf
