In a prospective study on 516 breast cancer patients flow cytometry DNA ploidy and number of cell populations (defined as number of DNA stem lines) detected in the primary tumor were evaluated for prognostic purposes. the median follow-up time was about 5 years. in the 241 node negative cases, those patients with three or more cell populations had the worst prognosis, with a distant recurrence-fre

OBJECTIVE: To compare the lumbar infusion test and the cerebrospinal fluid (CSF) tap test for predicting the outcome of shunt surgery in patients with suspected normal pressure hydrocephalus. METHODS: 68 patients with suspected normal pressure hydrocephalus were studied. The absence of preceding history indicated idiopathic disease in 75% of these. All patients were assessed twice with walking and

The association between humoral immunity to unique and conserved epitopes of the Chlamydia trachomatis 60-kDa heat-shock protein (hsp60) and immunity to human hsp60 was examined in 129 women with laparoscopically verified pelvic inflammatory disease. An ELISA was used to detect antichlamydial IgG and IgA antibodies, IgG antibodies to recombinant human hsp60, and antibodies to two synthetic peptide

Objective: To determine the importance of IgM antibodies against phosphorylcholine ( aPC), a novel protective factor for cardiovascular disease ( CVD), in a population with a non-western life style as compared with a Swedish control group. Methods and results: Risk factors for cardiovascular disease were determined in a group of 108 individuals aged 40-86 years from New Guinea and 108 age-and sex-

Background. This study was performed to establish a model for quantitative measurements of a number of basic peritoneal transport parameters, particularly transperitoneal clearances (Cl) of macromolecules, during mouse peritoneal dialysis. Methods. Mice were anaesthetized using 3% isofluorane inhalation anaesthesia. The right jugular vein and the left femoral artery were cannulated for infusion a

The purpose of the present study was to investigate the distribution of suicide during the months of the year and the days of the week in severe depression. A total of 1206 in-patients rated at discharge from the Department of Psychiatry, Lund, Sweden, on a multiaxial diagnostic schedule received the diagnosis severe depression/melancholia between 1956 to 1969. When followed up to 1998, a total of

Popular Abstract in Swedish Det övergripande området för min studie är lärararbetet. Initialt riktar jag blickarna mot lärare som verkar i den svenska grundskolan. Den övergripande forskningsfrågan lyder: Hur är lärararbetet? Även om det i grundad teori framstår som önskvärt att forskaren ska ge sig ut på fältet utan förutfattade idéer och perspektiv som tvingar data in i förutbestämda analyser, gThe aim of this study is to generate a grounded theory about the work done by teachers. The initial area of data collection was the work done by teachers in their non-regulated hours, in which the teachers are expected to carry out professional activities like planning, preparation, correcting and spontaneous contacts with students, parents and colleagues. Data was collected and analysed according

No randomised study in the rituximab era has been performed specifically to evaluate addition of etoposide to treatment of diffuse large B-cell lymphoma (DLBCL). The aim of this study was to compare the outcome with three chemotherapy regimens (R-CHOP-21, R-CHOP-14 and R-CHOEP-14) in a population-based cohort in terms of overall survival, adjusted for clinical prognostic factors. Through the Swedi

BACKGROUND: CYP2C8/9 polymorphisms may influence breast cancer-free survival after diagnosis due to their role in the metabolism of tamoxifen, paclitaxel, and other chemotherapy. cytochrome P450 (CYP)2C8/9 metabolise arachidonic acid to epoxyeicosatrienoic acids, which enhance migration and invasion in vitro and promote angiogenesis in vivo. We aimed to investigate the frequency of CYP2C8/9 polymo

Zinc-positive neurons and terminals, known to be associated with the glutamatergic projections in the brain, can be demonstrated by the histochemical Timm method and later modifications thereof. The adult rat neocortex contain a uniform lamination of zinc-positive cells with specific projections to, e.g., the striatum. We have previously reported that fetal neocortical grafts implanted in the adul

Previous studies using echocardiography in healthy subjects have reported conflicting data regarding the percentage of the stroke volume ( SV) of the left ventricle ( LV) resulting from longitudinal and radial function, respectively. Therefore, the aim was to quantify the percentage of SV explained by longitudinal atrioventricular plane displacement ( AVPD) in controls, athletes, and patients with

OBJECTIVE: In acute lung injury (ALI) mechanical ventilation damages lungs. We hypothesised that aspiration and replacement of dead space during expiration (ASPIDS) allows normocapnic ventilation at higher end-expiratory pressure (PEEP) and reduced tidal volume (V(T)), peak and plateau pressures (Paw(peak), Paw(plat)), thus avoiding lung damage. SETTING: University Hospital. PATIENTS: Seven consec

Background Patch test reactivity to nickel varies over time. To what extent this variation is associated with fluctuations in the T-cell reactivity to nickel is not known. Objectives Our aim was to investigate the relationship between variation over time in the patch test and the systemic T-cell reactivity to nickel. Methods Patients (n = 15) with a history of contact allergy to nickel were subjec

BACKGROUND: The study aimed to investigate patient and spouse perception of cognitive functioning 1 to 2 years after coronary artery bypass grafting. METHODS: Seventy-six married patients who had undergone coronary artery bypass grafting were selected and sex- and age-matched with 75 concurrent married patients who had undergone percutaneous transluminal coronary angioplasty. Couples received a le

The recognition of a strong etiological relationship between infection with high-risk human papillomavirusses and cervical cancer has prompted research to develop and evaluate prophylactic and therapeutic vaccines. One prophylactic quadrivalent vaccine using L1 virus-like particles (VLP) of HPV 6, 11, 16 and 18 is available on the European market since the end of 2006 and it is expected that a sec

Lysine acetylation occurs in many protein targets, including core histones, transcription factors, and other proteins. Metastasis-associated protein 1 (MTA1) is implicated in the progression and metastasis of various epithelial tumors. Because MTA1 functions as a transcriptional coregulator, much of its role in cancer promoting processes are likely to involve its ability to regulate the transcript

Objective: To use proteomic analysis of cerebrospinal fluid to discover novel proteins and peptides able to differentiate between patients with stable mild cognitive impairment (MCI) and those who will progress to Alzheimer disease (AD). Design: Baseline cerebrospinal fluid samples from patients with MCI and healthy controls were profiled using surface-enhanced laser desorption/ionization time-off

The use of (U-Th)/He thermochronometry in old slowly cooled terranes has long been debated. Hence, studies of natural setting are needed to verify the expected diffusivity behaviour of helium. Our results demonstrate that the (U-Th)/He method can be applicable to samples older than 200 Ma, and that available helium diffusion models can reproduce the results obtained from the age-vs.-depth trends.
