Reduction of high cholesterol levels associated with younger age and longer education in a primary health care programme for cardiovascular prevention

Objective. To study possible social predictors for reduction of hyperlipidaemia in subjects offered lifestyle intervention in primary health care after an opportunistic screening. Setting. Primary health care in Sollentuna, Sweden. Design. Follow-up study of changes in high lipid levels in men and women aged 20-60 years participating in a voluntary screening and cardiovascular prevention programme

Immigrants in emergency care: Swedish health care staff's experiences

Background: During the past few decades Sweden has developed into a multicultural society. The proportion of patients with different cultural backgrounds increases, which naturally makes new demands on health care staff. Aim: To identify whether staff in somatic and psychiatric emergency care experienced problems in the care of migrants, and if so to compare these. Method: The study design was exp

Inhibition of dipeptidyl peptidase-4 augments insulin secretion in response to exogenously administered glucagon-like peptide-1, glucose-dependent insulinotropic polypeptide, pituitary adenylate cyclase-activating polypeptide, and gastrin-releasing peptide in mice

Inhibition of dipeptidyl peptidase- 4 ( DPP- 4) is currently being explored as a new approach to the treatment of type 2 diabetes. This concept has emerged from the powerful and rapid action of the enzyme to inactivate glucagon- like peptide-1 ( GLP- 1). However, other bioactive peptides with potential influence of islet function are also substrates of DPP- 4. Whether this inactivation may add to

Temperature quenched DODAB dispersions: Fluid and solid state coexistence and complex formation with oppositely charged surfactant

Dilute dispersions of the synthetic bilayer forming double-chained cationic lipid dioctadecyldimethylammonium bromide (DODAB) were investigated. In dispersions sonicated above the chain melting temperature T-m (approximate to45 degreesC) it was found by H NMR that about 50% of the surfactant chains remained fluid when the samples were cooled to room temperature, which is 20 degreesC below T-m. In

Terbutaline Enantiomer Separation and Quantification by Complexation and Field Asymmetric Ion Mobility Spectrometry-Tandem Mass Spectrometry.

Recently, we introduced a new approach to chiral separation and analysis of amino acids by chiral complexation and electrospray high-field asymmetric waveform ion mobility spectrometry coupled to mass spectrometry (ESI-FAIMS-MS). In the present work, we extended this approach to the separation of the drug compound terbutaline. Terbutaline enantiomers were complexed with metal ions and an amino aci

Effect of dissipation on the constitutive relations of bi-anisotropic media - the optical response

This paper discusses the restrictions that dissipation forces on the material parameters and responses of bi-anisotropic media. The treatment is a general time domain analysis where six-vector formalism is applied. Energy conditions set limitations on the optical response dyadics and dyadic susceptibility kernels of the material that have to be satisfied regardless the time dependence of the field

Effect of a prostaglandin E1 analogue (gemeprost) on uterine and luteal circulation in normal first trimester pregnancies. A Doppler velocimetry study

OBJECTIVE: To evaluate the effects of gemeprost on utero-placental and luteal circulation and on the embryo/fetus in normal first trimester pregnancies. STUDY DESIGN: Sixty-seven women with a normal first trimester pregnancy requesting termination of pregnancy for psychosocial reasons were randomly allocated to pre-operative treatment with vaginal suppositories containing placebo or gemeprost. The

The effect of propofol on actin, ERK-1/2 and GABA(A) receptor content in neurones

Aim: Interaction with the gamma-aminobutyric acid receptor (GABA(A)R) complex is recognized as an important component of the mechanism of many anaesthetic agents, including propofol. The aims of this study were to investigate the effect of propofol on GABA(A)R, to determine whether exposure of neurones to propofol influences the localization of GABA(A)R within the cell and to look for cytoskeletal

On the construction of universal families of hash functions via geometric codes and concatenation

In this paper we use coding theory to give simple explanations of some recent results on universal hashing. We first apply our approach to give a precise and elegant analysis of the Wegman-Carter construction for authentication codes. Using Reed-Solomon codes and the well known concept of concatenated codes we can then give some new constructions, which require much less key size than previously k

Phosphorylation of the oestrogen receptor alpha at serine 305 and prediction of tamoxifen resistance in breast cancer.

Phosphorylation of oestrogen receptor alpha at serine 305 (ERalphaS305-P) induces tamoxifen resistance in experimental studies, but does not influence response to other endocrine agents, such as fulvestrant. We evaluated ERalphaS305-P using immunohistochemistry in 377 breast carcinomas from premenopausal participants of a randomized trial (n = 248) and patients with advanced disease (n = 129). Amo

Nest-site selection and predation in Savi’s Warblers, Locustella luscinioides.

Capsule: Savi’s Warblers preferred sites dominated by high and dense Juncus and Rubus with thick litter, and avoided pure reeds; predation was higher in sites with less litter. Aim: To describe nest-site selection and identify which habitat and nest features influence predation risk. Methods: Comparisons were made between habitat characteristics measured at nest-sites and random points, and betwee

The base of the global Dapingian Stage (Ordovician) in Baltoscandia: conodonts, graptolites and unconformities

In the recently completed and formally ratified new series and stage classification of the Ordovician System, the base of the Middle Ordovician Series coincides with the base of the global Dapingian Stage. In the Global Stratotype Section and Point (GSSP) of this stage, which is located at Huanghuachang in southern China, the base of the Dapingian Stage is defined its the level of first appearance

Cystatin E is a novel human cysteine proteinase inhibitor with structural resemblance to family 2 cystatins

A new member of the human cystatin superfamily, called cystatin E, has been found by expressed sequence tag (EST) sequencing in amniotic cell and fetal skin epithelial cell cDNA libraries. The sequence of a full-length amniotic cell cDNA clone contained an open reading frame encoding a putative 28-residue signal peptide and a mature protein of 121 amino acids, including four cysteine residues and

Factor V leiden and prothrombin gene mutation: risk factors for osteonecrosis of the femoral head in adults.

The purpose of the current study was to determine whether factor V Leiden and the prothrombin 20210A gene mutation are risk factors for osteonecrosis of the femoral head in different etiologic groups of osteonecrosis in adults and whether patients with idiopathic osteonecrosis of the femoral head have a higher frequency of thromboembolic events compared with the general population. We investigated

Stereological assessment of vulnerability of immunocytochemically identified striatal and hippocampal neurons after global cerebral ischemia in rats

Detailed quantitative analysis of the vulnerability of different hippocampal and striatal neurons to global forebrain ischemia has not previously been performed. Here we have studied the survival of immunocytochemically identified neurons using an unbiased stereological method in rats subjected to global forebrain ischemia for 30 min and sacrificed 48 h, 1 week or 4 weeks thereafter. Within the hi

Knee buckling: prevalence, risk factors, and associated limitations in function

BACKGROUND: Knee buckling is common in persons with advanced knee osteoarthritis and after orthopedic procedures. Its prevalence in the community is unknown. OBJECTIVE: To examine the prevalence of knee buckling in the community, its associated risk factors, and its relation to functional limitation. DESIGN: Cross-sectional, population-based study. SETTING: The Framingham Osteoarthritis Study. PAR

Potent synergic effect between ibuprofen and azoles on Candida resulting from blockade of efflux pumps as determined by FUN-1 staining and flow cytometry

Objectives: Resistance to antifungals often relates to efflux pumps exporting drugs; several modulators may block them, reverting resistance. Verapamil, beta-oestradiol and progesterone, known efflux pump inhibitors of human neoplastic cells, and ibuprofen were tested as potential modulators of resistance of Candida spp. Methods: Forty-two clinical isolates of Candida (38 fluconazole-resistant), t
