Neuroprotective and possible trophic actions of nicotine were studied in two types of experimental models: (1) one in which the meso-striatal dopamine system was subjected to partial hemitransection, and regional glucose utilization (using 2-[3H]deoxyglucose) and blood flow (using [14C]iodoantipyrine) were measured by computer-assisted quantitative autoradiography based on a double-isotope techniq
A method to study total deposition of aerosol attached radon progeny in children and adults have been validated and used in home environments. Two persons, one child and one adult are tested simultaneously, thus inhaling from the same aerosol and allowing for a direct comparison. The aim of the study was to increase the knowledge of the lung deposition and thereby the knowledge of the radiation do
This study investigates the mechanisms of (de)coding modality, focusing on the interpretation of utterances containing the modals must, may, måste, and kan. The main research question posed in this study is what enables the interlocutors to interpret modal expressions so that communicative goals are achieved. To answer this general question, Coates's (1983) study on modal contexts is initially rep
In vitro reassembled aggregates of cartilage proteoglycan (aggrecan) were studied by glycerol spraying/rotary shadowing electron microscopy and compared to the corresponding native (i.e. never dissociated) structures. In both cases a tightly packed central filament structure was observed consisting of the hyaluronate binding region (HABR) of the proteoglycan, link protein (LP) and hyaluronate (HA)
A new approach to the design of time windows is presented for detection of transient-evoked otoacoustic emissions (TEOAE). The windows are designed with reference to a minimum mean square error criterion involving the correlation properties of the ensemble of responses. Latency information is introduced in the detection process by windowing at different scales that result from wavelet decompositio
Vitamin D supplements have been used to prevent fractures. The effect may be mediated through increased bone mass, but also through reduced falling propensity. The aim of this study was to evaluate the association between 25-hydroxy vitamin D levels (25OHD), fall-associated variables (including tests of functional performance), and fracture in ambulatory women. At baseline 25OHD was measured in 98
Eukaryotic cell cycles are controlled by the activities of cyclin-dependent kinases (cdks). The major cdk in budding yeast, Saccharomyces cerevisiae, is Cdc28p. Activation of Cdc28p requires phosphorylation on threonine 169 and binding to a cyclin. Thr-169 is phosphorylated by the cdk-activating kinase (CAK), Cak1p, which was recently identified as the physiological CAK in budding yeast. Here we p
Granulosa and theca cell tumors of the ovary account for 2-3% of ovarian malignancies. This study includes 54 patients with the diagnosis of granulosa cell tumors of the ovary treated between 1953 and 1987. Median age at diagnosis was 57 (27-83) years. The lesions were staged according to FIGO. The number of patients in various stages was IA, 41; IB, 3; IC, 3; IIB, 6; and III, 1. Median tumor size
A case is presented of extragenital abdominal choriocarcinoma without uterine lesion in a postmenopausal woman. Nineteen years after her antecedent pregnancy, a legal abortion, and thirteen years after her menopause, the patient was admitted to the hospital because of intermittent abdominal pain. Explorative laparotomy revealed a large tumour mass in the greater omentum, mesosigmoideum, peritoneal
The causes and extent of regional inequality in the process of economic growth are at the core of historical economic research. So far, much attention has been devoted to studying the role of industrialization in driving regional divergence. However, empirical studies on relatively unequal countries such as Italy and Spain show that inequality was already high at the outset of modern industrializa
PURPOSE: To develop a mapping model to estimate EQ-5D-3L from the Knee Injury and Osteoarthritis Outcome Score (KOOS).METHODS: The responses to EQ-5D-3L and KOOS questionnaires (n = 40,459 observations) were obtained from the Swedish National anterior cruciate ligament (ACL) Register for patients ≥ 18 years with the knee ACL injury. We used linear regression (LR) and beta-mixture (BM) for direct m
Introduction Sierra Leone has the world's highest maternal mortality, partly due to low access to caesarean section. Limited data are available to guide improvement. In this study, we aimed to analyse the rate and mortality of caesarean sections in the country. Methods We conducted a retrospective study of all caesarean sections and all reported in-facility maternal deaths in Sierra Leone in 2016.
This paper is based on a lecture held in Nagoya, Japan as part of a seminar on issues relating to disabled women, sexuality and sexual and reproductive health and rights (SRHR). I present preliminary results from the research project Sexual Citizenship and Disability: Implications for Theory, Practice and Policy, which focuses on sexual rights for people with mobility impairments. The data compris
This study examines the consequences of grade inflation at the upper secondary education level on enrolment in higher education and earnings for Sweden. Although grade inflation is unfair and may imply inefficient allocation of human resources, current knowledge of grade inflation effects on individual outcomes is scarce. One explanation is probably the challenge of measuring and estimating causal
