Monitoring Aerosol Elemental Composition in Particle Size Fractions for Predicting Human Respiratory Uptake

Proton induced X-ray emission analysis is useful in measuring changes in particle size distribution of trace elements on exposure of aerosol to the human lung environment and deposition in the air-ways. PIXE analysis is also useful in detecting variations in particle size distributions of elements as they occur in the atmosphere. For the case of lead aerosol along a highway, it is shown that the e

Basiliolides, a class of tetracyclic C19 dilactones from Thapsia garganica, release Ca2+ from the endoplasmic reticulum and regulate the activity of the transcription factors nuclear factor of activated T cells, nuclear factor-kappa B, and activator protein 1 in T lymphocytes

Calcium concentration within the endoplasmic reticulum ER) plays an essential role in cell physiology. We have investigated the effects of basiliolides, a novel class of C19 dilactones isolated from Thapsia garganica, on Ca2+ mobilization in T cells. Basiliolide A1 induced a rapid mobilization of intracellular Ca2+ in the leukemia T-cell line Jurkat. First, a rapid calcium peak was observed and in

Chlorophyll biosynthesis in higher plants. Regulatory aspects of 5-aminolevulinate formation

Chlorophyll, heme, phytochrome and siroheme biosynthesis in higher plants is regulated by the supply of their precursor 5-aminolevulinate (ALA), which is derived from glutamate. Glutamate conversion to ALA occurs only in the plastid and requires chloroplast coded tRNA(Glu) and nuclear coded glutamyl-tRNA synthetase, glutamyl-tRNA reductase and glutamate 1-semialdehyde aminotransferase. The chromos

Integral equation for spin dependent unintegrated parton distributions incorporating double In-2(1/x) effects at low x

In this paper we derive an integral equation for the evolution of unintegrated (longitudinally) polarized quark and gluon parton distributions. The conventional Catani-Ciafaloni-Fiorani-Marchesini (CCFM) framework is modified at small x in order to incorporate the QCD expectations concerning the double ln(2)(1/x) resummation at low x for the integrated distributions.

Risk faktors for fracture in middle-aged men and women

Popular Abstract in Swedish Sedan årtionden ökar antalet frakturer över hela världen, och i alla ålderskategorier. Frakturer leder ofta till längre tids funktionsinskränkning, sämre livskvalitet och ibland till döden. Projektet ?Malmö Förebyggande Medicin?, an populationsbaserad, prospektiv studie av 22 444 män, medelålder 44 år, och 10 902 kvinnor, medelålder 50 år, är väl lämpad för studier av vThe number of fractures is increasing worldwide, and fractures frequently cause long-term disability, impaired quality of life and sometimes death. The Malmö Preventive Project, a population-based, prospective study, consisting of 22 444 men, mean age 44 and 10 902 women, mean age 50 years, provides data for evaluation of common public health conditions, such as fracture and diabetes. The follow-u

Cobalt 2,2 '-biimidazole complexes co-crystallised with di-acids - synthesis, structure and quantum chemical calculations

The synthesis and crystal structure of [Co(Hbiim)(2)(H(2)biim)](2)(p-OOCC6H4COOH)(2).H2O (2) is presented. The cobalt(III) complexes are bridged by terephthalates and water molecules, giving a rare, five-fold interpenetrated, net built from 3-connected nodes. The vertex symbol (topology) of this net is determined to 4 122 122, 4 126, 12(4) 12(6) 12(6), or 4 12(2), 4 12(2), 12(3), using the Wellsia

Undervisning i konsultationsmetodik behövs i läkarutbildningen. Utvärdering med studentenkät och fokusgruppsintervjuer

Inom läkarutbildningen vid Lunds universitet förekommer undervisning i samtalsmetodik under såväl den prekliniska som den kliniska delen. Under kursen i samhällsmedicin på termin 10 träffas grupper om sex till sju studenter och en gruppledare fyra gånger för att diskutera studenternas videoinspelade konsultationer. Vi har utvärderat detta moment genom en klassrumsenkät till samtliga studenter och At Lund University Medical School communication skills are taught during both the preclinical and clinical part of the medical programme. As part of the training during the 5th year the students are required to videotape at least one patient consultation at a local primary health care centre. The students then meet in groups of 6-7 participants and a group leader to watch the recorded consultation

Limnic responses to increased effective humidity during the 8200 cal. Yr BP cooling event in southern Sweden

Highly resolved sediment stratigraphic and stable isotope records from a lake in south-central Sweden give evidence of relatively humid summers during the wide-spread cold event at c. 8200 cal. BP. A transient lake-level rise led to increased catchment erosion followed by enhanced phytoplankton production and disturbance of the Chara-dominated algal community. An associated increase in the deposit

Biliary microflora in acute cholecystitis and the clinical implications

A prospective bacteriologic investigation was made in 43 consecutive patients (mean age 63 years) operated on for acute cholecystitis. Gallbladder bile and wall were cultured, using four methods and with special attention to optimal anaerobic technique. Cultures were positive in 72% of the patients, yielding a wide variety of species (21 species among 48 isolates). Anaerobes constituted 23% of the

Disturbances of speech prosody following right hemisphere infarcts

The ability to perceive and express emotional, as well as number of linguistic prosodic qualities of speech was tested in 20 Swedish-speaking patients with right-sided cortical, as well as purely subcortical brain infarcts, and in 18 normal controls. The infarcts were assessed by clinical neurological examination, and by CT, EEG, and measurements of regional cerebral blood flow (rCBF). In the pati

Sensitivity in Shear Strength of Longitudinally Reinforced Concrete Beams to Fracture Energy of Concrete

The size effect in shear strength of longitudinally reinforced beams is studied by means of a nonlinear fracture mechanics model. According to the actual theoretical study, structure size should be normalized to an intrinsic length parameter of the concrete. This length parameter is proportional to the fracture energy G//F of the concrete. It is found that the shear strength of a concrete beam may

Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads

The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical meas
