The densities and viscosities of ternary mixtures of mono(ethylene glycol) (MEG) + 2-amino-2-methyl-1-propanol (AMP) + water have been measured at temperatures of 25 to 40 degreesC. The water content varied in the range 1.4 to 15.6 mol %, and the amine concentration varied from 0 to 11.8 mol %. The excess volumes were calculated from the experimental data and fitted to a simple Redlich-Kister type

Malacoplakia is a granulomatous disease with a histiocytic infiltrate containing calcified structures called Michaelis-Gutmann bodies. These structures are considered to represent an abnormal response to infection involving defective lysosomes and abnormal microbubular assembly. The disease most frequently involves urinary and genital tracts, but has also been described from most other organs. Her

A persistent vegetative state (severe dementia) developed in a 30-year-old man following hypoglycemic coma. Despite the poor clinical outcome, sensory evoked response recovered between 6 and 34 months after the insult. The cerebral blood flow level at rest after 34 months was slightly above the normal range. This finding contrasts with the low cerebral blood flow regularly reported in patients who

Background: The objective of this study was to determine whether the frequency of sexually transmitted diseases (STDs) and some reproductive events in women with experience of casual travel sex (CTS) abroad with previously unknown male partners differed when compared to women lacking such experience. Methods: Nine hundred and ninety-six women seeking contraceptive advice from two family planning c

Local inflammatory reactions affect the integrity of intestinal epithelial cells, such as E-cadherin-mediated cell-cell interactions. To elucidate this event, we investigated the effects of an inflammatory mediator, leukotriene D(4 )(LTD(4)), on the phosphorylation status and properties of vinculin, a multi-binding protein known to interact with both the E-cadherin-catenin complex and the cytoskel

Using data on Swedish adolescents, this study examines (1) perceptions of the addictiveness and mortality risk of smoking, (2) the effects of these perceptions on smoking behaviour, and (3) the role of various smoking risk information sources. The average respondent believed that 46 out of 100 smokers would die from diseases caused by their smoking. As to addictiveness perceptions, the average res

Aims: To determine the effects of a nurse-led intervention designed to improve self-management of patients with heart failure in a primary health care setting regarding health-related quality of life and depression. Methods: Patients at eight primary health care centres were screened by the Diagnosis Related Groups registry for the diagnosis of heart failure and eligibility for a cluster randomise

Studies suggest that skin cancer aggregates within families; however, the risk of skin cancer associated with having an affected sibling or parent by subtype, tumor site, and age at diagnosis has not been established. The 2006 update of the Swedish Family-Cancer Database was used to calculate standardized incidence ratios (SIRs), representing the ratio of cancer risk among individuals with affecte

The increased schizophrenia risks for residents of cities with high levels of competition and for members of disadvantaged groups (for example migrants from low- and middle-income countries, people with low IQ, hearing impairments or a history of abuse) suggest that social factors are important for aetiology, Dopaminergic dysfunctioning is a key mechanism in pathogenesis. This editorial is a selec

The blood lead (PbB) and blood cadmium (CdB) levels, as well as the parental smoking habits, of 133 children aged 4 to 11 years were studied. The children were from a town with a lead smeltery and a surrounding rural area. There was a significant association between the higher PbB levels of the children and involuntary (parental) smoking in the home. The CdB levels of the children were not affecte

In a joint experimental and theoretical work the optical response and excited-state character of two novel conjugated polymers for photovoltaic applications are studied. The polymers, alternating polyfluorene (APFO) Green 1 and APFO Green 2, are both copolymers of fluorene, thiophene, and electron accepting groups. The band gaps are extended into the red and near infrared with onsets of 780 and 10

The Wnt-5a gene encodes a secreted protein that controls several normal processes during embryogenesis and development of adult tissues by as yet unknown mechanisms. Endogenous expression of Wnt-5a mRNA is known to occur in both mouse and human mammary cell lines. To investigate the biological role of Wnt-5a in the human mammary epithelial cell line HB2, we used an antisense approach to repress en

Objective: To analyze the distribution of 3 collagen types in healthy tympanic membranes, during healing of a perforation, and during infection. Design: Immunohistochemical study of collagen types I, II, and III in the tympanic membranes of healthy rats as well as during healing of a perforation and in the presence of infection with Streptococcus pneumoniae at various time points. Setting: Laborat
