The International Collaboration of Epidemiological Studies of Cervical Cancer has combined individual data on 11,161 women with invasive carcinoma, 5,402 women with cervical intraepithelial neoplasia (CIN)3/carcinoma in situ and 33,542 women without cervical carcinoma from 25 epidemiological studies. Relative risks (RRs) and 95% confidence intervals (CIs) of cervical carcinoma in relation to numbe

A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is inte

OBJECTIVE: Early enteral nutrition with fiber-containing solutions plus Lactobacillus may reduce bacterial translocation and minimize the incidence of infections after surgery. METHODS: In a prospective, randomized trial in three groups (n = 30/group) of patients after major abdominal surgery, we compared our previous regimen with parenteral nutrition or fiber-free enteral nutrition (group A) with

As increased nutrient availability due to drainage is considered a major cause of eutrophication in wetlands rewetting of drained wetlands is recommended as a restoration measure. The effect of soil drying and rewetting on the contribution of various nutrient release or transformation processes to changed nutrient availability for plants is however weakly understood. We measured effects of soil dr

Two alternative hypotheses have been proposed to explain how social and genetic mating systems are interrelated in birds. According to the first (male trade-off) hypothesis, social polygyny should increase extrapair fertilizations because when males concentrate on attracting additional social mates, they cannot effectively protect females with whom the); have already paired from being sexually ass

The breeding biology of great tits (Parus major) was studied in two forests of maritime pine (Pinus pinaster) on the west coast of Portugal, 200 km apart: Leiria (north) and Apostica (south). These two forests are located in a transition zone between Atlantic climate in the north, and Mediterranean climate in the south. Breeding onset was, on average, in the second and third week of March, which a

The role of sphingosine kinase (SphK) on basic fibroblast growth factor (bFGF)-induced proliferation of cerebral, aortic and coronary smooth muscle cells (SMC) was addressed using D-erythro-N,N-dimethylsphingosine (DMS), an inhibitor of SphK which blocks conversion of sphingosine to sphingosine-1-phosphate (S1P). DMS concentration-dependently reduced the bFGF-induced proliferation of rat cerebral

The one-photon absorption (OPA) properties of donor-pi-bridge-acceptor-pi-bridge-donor (D-pi-A-pi-D)-type 2,1,3-benzothiadiazoles (BTD) were studied with two dimensional (2D) site and three dimensional (3D) cube representations. The 2D site representation reveals the electron-hole coherence on electronic state transitions from the ground state. The 3D representation shows the orientation of transi

BACKGROUND: Cervico-isthmic pregnancy is a rare occurrence and until the use of current ultrasonographic techniques was associated with a disastrous outcome for women desiring to maintain their fertility. CASE REPORT: A 39-year-old woman was diagnosed at 12 weeks of amenorrhoea with an intra-uterine non-viable pregnancy and a low implantation of the gestational sac. Medical management of this situ

Background: Considerable lives and money could be saved if one could detect early stages of lapsing/ relapsing behavior in addicted persons (e.g., in safety-sensitive workplaces) and could disclose harmful drinking in social drinkers. Due to the serious public health problem of alcohol use and abuse worldwide, markers of alcohol use have been sought. Both ethyl glucuronide (EtG) and phosphatidyl e

PURPOSE: To describe a complication of thrombolytic therapy used to treat graft limb occlusion precipitated by distal migration and kinking of an abdominal aortic stent-graft. CASE REPORT: A 5.5-cm abdominal aortic aneurysm (AAA) in a 66-year-old woman was treated with Vanguard bifurcated stent-graft. At the 1-year follow-up, she complained of left leg claudication. Computed tomography (CT) showed

This phase 2 study evaluated the safety and efficacy of alemtuzumab in 22 patients with advanced mycosis fungoides/Sezary syndrome (MF/SS). Most patients had stage III or IV disease, reduced performance status, and severe itching. The overall response (OR) rate was 55%, with 32% of patients in complete remission (CR) and M in, partial remission (PR). Sezary cells were cleared from the blood in 6 o

Some groups have to face threats and dangers professionally with maintained cognitive functioning, which implies a need to know both the extent to which maladaptive reactions occur and the factors that may affect it. This study examines self-reported reactions and performance when facing risks and dangers on peacekeeping observer missions. The sample consisted of 154 military observers.,A self-mad

n order to make attribute grammars useful for complicated analysis tasks, a number of extensions to the original Knuth formalism have been suggested. One such extension is the collection attribute mechanism, which allows the value of an attribute to be defined as a combination of contributions from distant nodes in the abstract syntax tree. Another extension that has proven useful is circular attr

In patients with severe head injuries raised intracranial pressure (ICP) constitutes the most important cause of mortality. Several new therapies for increased ICP have recently been suggested and it is of importance to study the physiological effects of these treatments in animal experiments during steady state conditions. A porcine model for evaluation of cerebral haemodynamics and metabolism du
