Modern sunscreens contain particles like TiO2 having sizes of 25-70 nm and acting as a reflecting substance. For cosmetic reasons the particle size is minimized. Questions have been raised to what degree these nano particles penetrate the skin barrier, and how they do affect the human. The EU funded project "Quality of skin as a barrier to ultra-fine particles" - NANODERM has started with the purp
Sense of coherence (SOC), e.g. meaningfulness of life, is according to the sociologist A. Antonovsky a health-promoting construct, which has been used in a number of descriptive studies in various populations. The aim of this population-based cross-sectional study was to investigate if middle-aged women with a self-reported low level of SOC also differed in biological variables, e.g. related to gl
A number of finite element (FE) models have been developed, starting with a purely magnetic one. The magnetic model was verified against analytical solutions and the commercial FE-programme ANSYS. The magnetic model was then coupled to the wave-equation, resulting in a model governing linear magnetostriction. In the magnetostrictive model a property of two degrees of freedom, that is, displacement
The cytogenetic, hematologic, and clinical characteristics of a 13-year-old girl with acquired t(6;9)(p23;q34) and dysmyelopoietic syndrome developing into acute myelomonocytic leukemia are described, bringing the total number of patients with t(6;9) and hematologic disease described in the literature up to 19. The diagnosis has been acute myeloid leukemia in the great majority of these patients;
Species individualistic responses to warming and increased UV-B radiation are moderated by the responses of neighbors within communities, and trophic interactions within ecosystems. All of these responses lead to changes in ecosystem structure. Experimental manipulation of environmental factors expected to change at high latitudes showed that summer warming of tundra vegetation has generally led t
Objective Recent studies suggest an increased prevalence of obstetric complications in female carriers of hereditary or acquired thrombophilias. The aim of the study was to determine if carriership of the factor V (FV) Leiden mutation (activated protein C [APC] resistance) is higher in women who have had of placental abruption during pregnancy. Design A retrospective case-control study. Setting Un
Oxygen consumption (FO2) and lactate production (Flac) were measured during spontaneous activity in the guinea-pig mesotubarium. During spontaneous contractions FO2 increased to maximally 0.270 +/- 0.025 mumol min-1g-1 (n = 23), followed by a rapid fall immediately upon relaxation. In the relaxed period (5-15 min) between spontaneous contractions FO2 continued to slowly decrease by about 25% towar
A 16 s old gas-phase ambient temperature and 1% relative humidity reaction mixture of ozone and R-limonene (ca. 1:10) was sampled on XAD-2 resin followed by pressurized liquid extraction with dichloromethane at ambient temperature. Low temperature on-column injection and gas chromatography (GC) revealed equal amounts of diastereomeric secondary endo-limonene ozonides, in addition to 4-acetyl-l-met
Changes in tolerance levels of soil bacterial communities pre-exposed to different metal concentrations and then reestablished in an unpolluted soil were examined during a one year incubation period using the thymidine incorporation technique. The study was performed with a sterilized agricultural soil, which was reinoculated with bacteria extracted from soils previously contaminated with high dos
Force generation and tissue glucose metabolism were measured in the urinary bladder smooth muscle from rats with streptozotocin-induced diabetes (7-8 wk duration). Bladder wet wt was almost 4-fold higher in the diabetic animals compared with the untreated controls. Morphological analysis showed that the growth was associated with hypertrophy of the smooth muscle component in the bladder wall. Forc
Let D be a finitely connected bounded domain with smooth boundary in the complex plane. We first study Banach spaces of analytic functions on D . The main result is a theorem which converts the study of hyperinvariant subspaces on multiply connected domains into the study of hyperinvariant subspaces on domains with fewer holes. The Banach spaces are defined by a natural set of axioms fulfilled by
