Ultrasonic-trap-enhanced selectivity in capillary electrophoresis.

We combine ultrasonic trapping and capillary electrophoresis (CE) with the goal to detect ultra-low concentrations of proteins via size-selective separation and enrichment of antibody-coated latex spheres. An 8.5 MHz standing ultrasonic wave is longitudinally coupled into the sub-100-small mu, Greekm diam capillary of the CE system. Competition between acoustic and viscous forces result in in-flow

Sexual experiences in childhood: young adults' recollections

Childhood sexuality and children's sexual experiences have become increasingly important to study because our knowledge on the impact of sexually abusive experiences on children's developing sexuality has increased. The main aim of this paper was to study aspects of young adults' recollections of their sexual experiences before the age of 13, solitary and shared, mutual as well as coercive. Anonym

Intrauterine infection may be a major cause of stillbirth in Sweden

Aim of the study. To investigate intrauterine infection as a cause for unexplained stillbirth. Methods. Chorioamnionitis was studied in a material of stillbirths (117 subjects from the years 1985-1994) from a region in the south Sweden. Control material (126 alive and healthy newborns and with healthy mothers) was gathered from the same region. Results. Chorioamnionitis was a common diagnosis bo

Constraining the Southern Part of the Greenland Ice Sheet since the Last Glacial Maximum from Relative Sea-Level Changes, Cosmogenic Dates and Glacial-Isostatic Adjustment Models

Popular Abstract in Swedish Jordens havsnivå förändras kontinuerligt. I ett längre geologiskt tidsperspektiv styrs förändringarna av processer i jordens inre, men i ett kortare tidsperspektiv spelar yttre processer, såsom tillväxt och avsmältning av inlandsisar, stor roll för havets nivåförändringar. Det grönländska istäcket är idag norra halvklotets enda inlandsis och dess tillväxt och avsmältninNew results are presented from the investigation of relative sea-level changes in the Nanortalik and Qaqortoq-Narsarsuaq areas in SW Greenland from c. 11 000 cal. years BP to the present. Isolation and transgression sequences from seven lakes and seven tidal basins are identified using some of the traditional methods such as stratigraphic description, magnetic susceptibility, saturated induced rem

Abstract in Spanish El objeto de este estudio es el Programa Social Agropecuario (PSA) y su interacción con diferentes actores locales en la conformación de las ferias francas en la provincia de Misiones. Estos espacios de comercialización de la pequeña producción agropecuaria comenzaron a organizarse a partir de 1995 y contaron con la participación no sólo del PSA, sino también del gobierno proviThe object of study of this article is the Agriculture Social Program (PSA) and its interaction with diverse local actors in the constitution of the farmers' markets in the province of Misiones, Northeastern Argentina. These markets are social and political spaces for commercialization of small scale agriculture production. The first one emerged in 1995 thanks to the participation of a network of

Imaging of neonatal arterial thrombosis

The case of a neonate who presented with symptoms of upper limb ischemia related to spontaneous multiple arterial and venous thromboses that were demonstrated by colour Doppler sonography and digital subtracted angiography is reported. The presentation of limb ischaemia at birth may be the warning sign of simultaneous cerebral infarction.

CYP17 genetic variation and risk of breast and prostate cancer from the national Cancer Institute Breast and Prostate Cancer Cohort Consortium (BPC3)

CYP17 encodes cytochrome p450c17 alpha, which mediates activities essential for the production of sex steroids. Common germ line variation in the CYP17 gene has been related to inconsistent results in breast and prostate cancer, with most studies focusing on the nonsynonymous single nucleotide polymorphism (SNP) T27C (rs743572). We comprehensively characterized variation in CYP17 by direct sequenc

GABA transporters (GAT-1) in Alzheimer's disease

The presynaptically located gamma-aminobutyric acid (GABA) transporter (GAT-1) was studied in a group of patients with Alzheimer's disease (AD) and in a control group using the GAT-1 selective radioligand [3H]tiagabine. Post mortem brain tissue from frontal cortex, temporal cortex, and caudate nucleus from 18 AD patients and 23 age-matched controls were studied. The binding was saturable (Kd 26 nM

Biases in the recovery and interpretation of micropalaeontological data

Bias caused by collecting and processing bulk samples is largely independent of what fossil clade or mineral is searched for. Instead, different methods bias the data to a different, frequently very large, degree. Furthermore, biases accumulate with each recovery step, and the sum may be extreme unless appropriate methods to minimize it are employed. The effects depend on what the data are used fo

Traumasjukvården har satts under luppen i södra sjukvårdsregionen. Peer review-system för bättre vård

I södra sjukvårdsregionen har ett arbete inletts för att kontinuerligt genomföra sakkunniga granskningar (sk peer review) av traumasjukvården inom regionen. I en första granskningsomgång har sex akutsjukhus deltagit. Resultaten har sammanställts i ett granskningsdokument, som gett upphov till såväl uppmärksamhet och diskussion som konkreta åtgärder på det granskade sjukhuset. Granskningsdokument

Chlamydial antibodies and risk of prostate cancer

Objective: We assessed the risk of prostate cancer by exposure to Chlamydia trachomatis. Method: Seven hundred thirty eight cases of prostate cancer and 2,271 matched controls were identified from three serum sample banks in Finland, Norway, and Sweden by linkage to the population based cancer registries. Results: A statistically significant inverse association (odds ratio, 0.69; 95% confidence in

Structure of Normally Deformed States in 80Sr

High-spin states were populated in Sr-80 With the reaction Ni-58(Si-28,alpha 2p), using a 130 MeV Si-28 beam from the 88-Inch Cyclotron at LBNL. Gamma rays were detected with Gammasphere. and evaporated alphas and protons were detected with the Microball. The level scheme has been extended, and angular distributions of many of the transitions have been measured. A portion of the data was taken usi
