Radioanalytical determination of Fe-55 and Ni-63 in the environmental samples

The radioanalytical procedures for the determination of neutron activation isotopes (Fe-55 and Ni-63) in environmental samples (water, sediment, sail and biological material) are described. The procedures are based on the coprecipitation of Fe-55 with iron hydroxide in natural and reactor water, ashing and mineralization of sediments, soil and biota samples, and the sequential separation and purif

Transvaginal sonography, saline contrast sonohysterography and hysteroscopy for the investigation of women with postmenopausal bleeding and endometrium > 5 mm

OBJECTIVES: To determine the ability of transvaginal ultrasound, with or without saline infusion, to detect focally growing lesions in the uterine cavity in women with postmenopausal bleeding and endometrium > 5 mm, and to determine the accuracy of conventional ultrasound, saline contrast sonohysterography and diagnostic hysteroscopy under general anesthesia to diagnose endometrial polyps, submuco

The surface band structure of Li/Be(10(1)over-bar0)

A photoemision study of the surface states on Be(10 (1) over bar0) after Li adsorption at room temperature is reported. The surface band structure was mapped along four high symmetry directions of the SBZ. Fairly large shifts in the surface band locations were obtained but all surface states observed experimentally after Li adsorption were found to correspond to Be-derived states and no Li-derived

The role of monoamines in suicidal behavior

Cerebrospinal fluid (CSF), urine, platelet and neuroendocrine challenge tests of monoaminergic function give evidence of monoamines, especially serotonin, playing an important role in suicidal behavior. However, additional clinical, social and biochemical factors are necessary to better define suicide-prone psychiatric patients.

Intramolecular charge transfer and locally excited states of the fullerene-linked quarter-thiophenes dyad

The ground and the excited state properties of the fullerene-linked quarter-thiophenes dyad were studied theoretically with the quantum chemistry method. To reveal the excited state properties of them in the vertical absorption process, the energies and densities of the HOMO and LUMO, the intramolecular charge transfer (ICT), locally excited (LE) are studied with transition density matrix, charge

Does smoking influence the risk of pouchitis following ileal pouch anal anastomosis for ulcerative colitis?

Objective. According to epidemiological studies, smoking habit is strongly associated with inflammatory bowel disease. Non-smokers, and especially recent ex-smokers, have an increased risk of ulcerative colitis (UC). Conversely, concerning Crohn's disease, the risk is increased among smokers. Pouchitis is the major long-term complication of restorative proctocolectomy for UC, and seems to be patho

The utility of the GHRH-arginine test for diagnosing GH deficiency in adults with childhood acute lymphoblastic leukemia (ALL) treated with cranial irradiation.

Context: The insulin tolerance test ( ITT) is the current standard diagnostic test for the diagnosis of adult GH deficiency ( GHD), but alternative tests, such as the GHRH- arginine test, have been proposed. Objective: We investigated the sensitivity and specificity of the GHRH- arginine test using ITT as the gold standard in diagnosing GHD in a group of young adults treated with cranial irradiati

Heidegger och autentisk fascism.

This article deals with Heideggers idiosyncratic relation to, and within German national socialism, how he saw his own position as more "authentic" than the version which ruled in Nazi Germany.

Pharmacokinetics and pharmacodynamics of meropenern in febrile neutropenic patients with bacteremia

Background: Pharmacodynamic investigations with antimicrobials define the relationship between the infecting organism and achievable drug concentrations with clinical outcome. Objective: To examine this relationship for meropenem in a population of patients who are at high risk of infection-related morbidity and mortality. Methods: The study was a retrospective analysis of a multicenter, randomize

Method to assess acoustical two-port properties of earplugs

An experimental setup for objective measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is presented. The setup has been applied on earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent duplicating the ear of a person. The insertion loss is co

Phenotypes in three Swedish families with X-linked retinitis pigmentosa caused by different mutations in the RPGR gene

PURPOSE: To assess the clinical phenotypes in three Swedish families with X-linked retinitis pigmentosa caused by different mutations in the RPGR gene. METHODS: Three families from different parts of Sweden, including nine patients with retinitis pigmentosa and six female carriers of X-linked retinitis pigmentosa, were examined clinically. Ophthalmologic examination included kinetic perimetry with

Search for B-s(0)-(B-s(0))over-bar oscillations in DELPHI using high-p(t) leptons

Oscillations in the B-s(0)- system were studied in events selected from about 4.3 million hadronic Z(0) decays registered by DELPHI between 1992 and 2000. This paper presents updates of two published analyses ([11, 12]). The first analysis, which utilizes leptons emitted with large momentum transverse to a jet, was improved by means of a better algorithm for the vertex reconstuction and a new alg

Attempts to improve absolute quantification of cerebral blood flow in dynamic susceptibility contrast magnetic resonance imaging: a simplified t1-weighted steady-state cerebral blood volume approach.

Background: Attempts to retrieve absolute values of cerebral blood flow (CBF) by dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) have typically resulted in overestimations. Purpose: To improve DSC-MRI CBF estimates by calibrating the DSC-MRI-based cerebral blood volume (CBV) with a corresponding T1-weighted (T1W) steady-state ( ss) CBV estimate. Material and Methods: 17 volunt

Combination of pre-operative radiotherapy and surgery suppresses local accumulation of collagen and TGF-beta 1 in rats

Background. The systemic and local tissue repair responses of radiation in combination with surgery are still unclear. We have studied the effect of fractionated pre-operative radiotherapy with or without subsequent laparotomy on collagen accumulation using a rodent model. Materials and methods. Thirty-two male Sprague-Dawley rats were divided into four groups (eight rats per group): 1) sham radia

Fermentation performance and intracellular metabolite patterns in laboratory and industrial xylose-fermenting Saccharomyces cerevisiae.

Heterologous genes for xylose utilization were introduced into an industrial Saccharomyces cerevisiae, strain A, with the aim of producing fuel ethanol from lignocellulosic feedstocks. Two transformants, A4 and A6, were evaluated by comparing the performance in 4-l anaerobic batch cultivations to both the parent strain and a laboratory xylose-utilizing strain: S. cerevisiae TMB 3001. During growth

A unique defect in the regulation of visceral fat cell lipolysis in the polycystic ovary syndrome as an early link to insulin resistance

The etiology of polycystic ovary syndrome (PCOS) is unknown. However, PCOS has a strong resemblance to the insulin resistance (metabolic) syndrome, where an increased rate of visceral fat cell lipolysis is believed to play a pathophysiological role. We hypothesized that primary defects in visceral lipolysis might also exist in PCOS. Ten young, nonobese, and otherwise healthy PCOS women were compar
