Mechanisms of bacterial resistance to fluoroquinolones may be grouped into three principal categories: gene mutations of DNA topoisomerase II (GyrA or GyrB), DNA topoisomerase IV (ParC or ParE), decrease of outer membrane permeation and upregulation of multi-drug efflux pump (active efflux system).(1) Efflux pumps are transport proteins removing toxic substrates ( including virtually all classes o

Simulated solar UV/TiO2 photocatalysis was efficient to detoxify a mixture of 100 mg phenol l(-1) and 50 mgp-nitrophenol (PNP) l(-1) and allow the subsequent biodegradation of the remaining pollutants and their photocatalytic products under photosynthetic aeration with Chlorella vulgaris. Photocatalytic degradation of phenol and PNP was well described by pseudo-first order kinetics (r(2) >0.98) wi

A new twin heat conduction microcalorimeter for the study of vapour sorption isotherms, sorption enthalpies and the kinetics of sorption has been developed. Each calorimeter has two calorimetric vessels which are connected by a steel tube. The upper vessel (a vaporization chamber) is charged with a vapour forming liquid and the lower vessel (a sorption chamber) contains the sorbent sample. An iden

Most computers today are embedded, i.e. they are built into some products or system that is not perceived as a computer. It is highly desirable to use modern safe object-oriented software techniques for a rapid development of reliable systems. However, languages and run-time platforms for embedded systems have not kept up with the front line of language development. Reasons include complex and, in

Amperometric biosensors for glucose, ethanol, and biogenic amines (putrescine) were constructed using oxidase/peroxidase bienzyme systems. The H2O2 produced by the oxidase in reaction with its substrate is converted into a measurable signal via a novel peroxidase purified from sweet potato peels. All developed biosensors are based on redox hydrogels formed of oxidases (glucose oxidase, alcohol oxi

We have studied the use of complimentary alternative medicine (CAM) among 233 consecutive breast cancer patients operated on at the Lund University Hospital, Sweden between 2002 and 2004. Questionnaires were administered preoperatively (n = 233), and again 3-6 months post-operatively (n = 167) and one year after surgery (n = 88). At baseline, 14,5% used CAM, 3-6 months post-operatively 14,4% used Bruket av naturläkemedel och andra faktorer som kan interagera med behandling av bröstcancer kartläggs i en pågående studie hos bröstcancerpatienter i Lund; i artikeln redovisas basdata för 233 patienter. Vid inskrivningen använde totalt 14,5 procent av patienterna naturläkemedel, vid 1-årskontrollen 18,2 procent. Sammanlagt 35 olika preparat användes, varav soja och övriga fytoöstrogener, vitlök,

An important question in human genetics is the extent to which genes causing monogenic forms of disease harbor common variants that may contribute to the more typical form of that disease. We aimed to comprehensively evaluate the extent to which common variation irk the six known maturity-onset diabetes of the young (MODY) genes, which cause a monogenic form of type 2 diabetes, is associated with

Popular Abstract in Swedish Denna avhandling tillhör området professions- och skolutvecklingsforskning. Avhandlingen tar upp hur förskolepersonal konstruerar sig som professionella subjekt, dvs hur förskolepersonal skapar sitt professionella jag, sin identitet, utifrån individuella såväl som kollektiva erfarenheter. Avhandlingen tar också upp på vilket sätt reflekterande samtal bidrar till denna sA major aim initially was to create a forum for reflective dialogue on the preschool professions and how it is experienced on a daily basis, so as to be able to investigate how members of the preschool staff construct their professional subject. The following are major questions that were posed: How do preschool staff members talk about themselves, their profession and their work? In what way does

Eight patients with Acanthamoeba keratitis were diagnosed and treated at our clinic between February 1991 and February 1993. Five of these were contact lens wearers, two had suffered recent corneal trauma and one had recently undergone penetrating keratoplasty. The diagnoses were based on both culture and histological examination of biopsy material in three cases, on culture alone in two cases and

We establish the existence of solitary wave solutions with exponential decay at infinity for a nonlinear dispersive partial differential equation. As a by-product, the existence of smooth solitary waves for the Camassa-Holm equation, modeling water waves and waves in elastic rods, is obtained.

Postmenopausal decline of estrogen production is associated with development of several degenerative disorders such as osteoporosis, neuroinflammatory diseases and vascular wall degeneration. These are associated with the activation of the cells of the monocyte-macrophage system in a context-dependent manner. Estrogen regulates differentiation, maturation and function of many cell types in this sy

The metabolites of two different Ripartites species, R. tricholoma (A. & S. ex Fr.) Karst. and R. metrodii Huijsm. were investigated. Three new sesquiterpenes were isolated from three different strains. In addition, the strains produced 13-oxo-9(Z),11(E)-octadecadienoic acid, psathyrellon A, 5-desoxyilludosin, an illudane (previously isolated from a Bovista sp.) 96042 and demethylovalicin, fiv

Background. Early enteral nutrition with solutions containing prebiotics (fiber) and probiotics (Lactobacillus) is suggested to reduce bacterial translocation and minimize the incidence of infections after liver transplantation. Methods. In a prospective, randomized placebo-controlled trial consisting of 95 patients, we compared the incidence of postoperative infections and other complications aft

Objective: The aims of this study were to investigate outcomes of older people's use of powered wheelchairs and risk factors for negative outcomes. Design: The study was a cross-sectional interview-study including 111 powered wheelchair users over 65 years of age. Results: All participants used their powered wheelchair in the summer; nearly all users regarded it as important and found that it gave

Palaeomagnetic data are used to study the configurations of continents during the Proterozoic. Applying stringent reliability criteria, the positions of the continents at 12 times in the 2.45- to 1.00-Ga period have been constructed. The continents lie predominantly in low to intermediate latitudes. The sedimentological indicators of palaeoclimate are generally consistent with the palaeomagnetic l
