The intracellular pathogenesis-related proteins have been identified in a broad range of flowering plants. Some display quite different patterns of expression, in many cases unrelated to the pathogenic response. Nevertheless, these proteins are all very similar and in most cases share more than 35% sequence identity. In this report we investigate the significance of a rather weak similarity betwee

A two-phase hollow-fiber (HF) liquid-phase microextraction (LPME) method was developed for determination of a quaternary ammonium compound surfactant, dicocodimethylammonium chloride, in aqueous samples. The porous HF was fixed on a metal rod support and was impregnated with approximately 6.6 mu L of organic extractant, which was immobilized in the HF pores. Surfactant extraction was facilitated b

Twenty-five patients with colorectal liver metastases had a subcutaneous portal connection with a peritoneal catheter implanted for the intraperitoneal (i.p.) administration of 5-fluorouracil (5-FU). In five patients, the malignant disease rapidly progressed and the implanted catheter system was never used. Among the remaining 20 patients, seven patients had i.p. 5-FU as adjuvant treatment followi

The ground and excited state properties (e.g., the intramolecular charge and energy transfer, and electron-hole coherence) of the chromophore of the asFP595 chromoprotein from Anemonia sulcata in the neutral and anionic forms are theoretically studied with quantum chemistry methods. The ground-state properties of the asFP595 in the neutral and anionic forms, such as the alternations of the bond le

Presently, unrestrained plethysmography is widely used to assess bronchial responsiveness in mice. An empirical quantity known as enhanced pause is derived from the plethysmographic box pressure [P-b( t), where t is time] and assumed to be an index of bronchoconstriction. We show that P-b(t) is determined largely by gas conditioning when normal mice breathe spontaneously inside a closed chamber in

The results of three separate studies on ankle fractures are presented. Clinical information is provided concerning the epidemiology and a comparison of closed versus open treatment, and a discussion is presented concerning what results can be expected 30 years after closed treatment for an ankle fracture.

Popular Abstract in Swedish Den tid vi i dagens samhälle betraktar som ungdomstid blir allt längre. De ungdomar som lämnar grundskolan tillhör en åldersgrupp som är större än på länge och det stora flertalet av dem är på väg in i svensk treårig gymnasieutbildning. En övergripande specialpedagogisk idé handlar om att alla människor bereds möjlighet att ta del i ett samhälle. Samtidigt finns inte nåThis longitudinal study draws the attention to some adolescents' images of the living-, study- and learning situations into, through and out of the upper secondary school period. The aim implies an examination of the ways a study group with "severe physical disabilities" describes their experiences of phenomena in connection with processes of co-operation and influence.

Historically, agriculturally induced CO2 release from soils has contributed to rising levels in the atmosphere. However, by using appropriate management, soils can be turned into carbon sinks. Many of the dryland regions of the world are characterised by degraded soils, a high incidence of poverty and a low capacity to invest in agriculture. Two well-proven soil organic matter models (CENTURY 4.0

Fluorescence lifetimes of formaldehyde excited by picosecond laser radiation with a wavelength of 355 nm were determined in nitrogen gas in a cell using time-resolved laser-induced fluorescence spectroscopy. The measurements were conducted at temperatures between 295 and 770 K and pressures up to 10 bar (1 MPa). Detection was broadband in most cases. Temperature and pressure were found to have a q

OBJECTIVES: Aortic dilatation, dissection and rupture are among the major causes of death in subjects with Marfan's syndrome. The aim of the study was to investigate the mechanical properties or compliance of the aorta in these subjects and compare them with a healthy age- and sex-matched reference population. MATERIALS AND METHODS: An ultrasound phase-locked echo-tracking system was used to deter

The ECL cells are endocrine/paracrine cells located in the acid-producing part of the stomach. They produce and secrete histamine and chromogranin A-derived peptides in response to circulating gastrin. Mobilized histamine stimulates acid secretion from adjascent parietal cells. The aims of the present investigation were to assess the usefulness of gastric submucosal microdialysis in studies of EC

Objective: To develop evidence based recommendations for the management of hip osteoarthritis (OA). Methods: The multidisciplinary guideline development group comprised 18 rheumatologists, 4 orthopaedic surgeons, and 1 epidemiologist, representing 14 European countries. Each participant contributed up to 10 propositions describing key clinical aspects of hip OA management. Ten final recommendation
