A systematic overview of radiation therapy effects in cervical cancer (cervix uteri)

A systematic review of radiation therapy trials in several tumour types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for cervical cancer is based on data from 1 meta-analysis and 34 randomize

Modelling the evolution of genomes with integrated external and internal functions

The genomes that organisms transmit between generations contain information about different kinds of functions. The genome with the "best" mix and number of genes for these functions is the one that natural selection favours. Here I introduce a new way to model simple organisms with genes for external and internal functions, and use it to study the evolution of genome size. The external functions

Pharmacokinetics of ceftazidime in acutely ill hospitalised elderly patients

The i.v. and i.m. dose pharmacokinetics of ceftazidime 1 g b.i.d. were investigated in steady state in 52 consecutive cases of hospitalised patients with underlying diseases and serious supervening bacterial infections. Following i.v. bolus injection, serum concentrations of greater than 4 mg/l persisted for 8 h in all patients. Compared to values found in younger patients studied previously, clea

Differential effects of selective oestrogen receptor modulators (SERMs) tamoxifen, ospemifene and raloxifene on human osteoclasts in vitro

Background and purpose: Several selective oestrogen receptor modulators ( SERMs) with oestrogen agonist effects in bone cells and without increased risk of breast and endometrial cancer have been developed. Here, we have investigated the effects of different types of SERMs on osteoclast differentiation, bone resorption and apoptosis in vitro. Experimental approach: Human peripheral blood- derived

Light-regulated release of liposomes from phospholipid membranes via photoresponsive polymer-DNA conjugates

A method for releasing tethered liposomes from a supported lipid bilayer in response to a light stimulus is described. The tethering is accomplished through the hybridization of end-functionalized DNA that resides on both the supported lipid bilayer and liposome surfaces. Normally consisting of cholesterol or lipid tails, the end group is replaced in this study by a photoresponsive polymer that pa

Petrology and ion microprobe U-Pb chronology applied to a metabasic intrusion in southern Sweden: A study on zircon formation during metamorphism and deformation

The Aker metabasite occupies a key position in a major tectonic lineament in southernmost Sweden, the Protogine Zone, which coincides closely with the eastern boundary of the late Mesoproterozoic Sveconorwegian orogen of southwest Scandinavia. Metamorphic reactions, associated with the transformation from isotropic gabbro to foliated garnet amphibolite, were identified from disequilibrium textures

Retrospective diagnostics of congenital cytomegalovirus infection performed by polymerase chain reaction in blood stored on filter paper

Capillary blood samples from 63 infants collected 3-7 days after birth, and thereafter stored on filter papers for 12-18 y, were tested for the presence of CMV DNA by the polymerase chain reaction (PCR) method. Of 16 infants with proven congenital CMV infection (positive virus isolation test in urine sampled within 1 week of age), 13 (81%) had a positive CMV PCR test and 3 (19%) a negative PCR tes

ADP Acting on P2Y13 Receptors Is a Negative Feedback Pathway for ATP Release From Human Red Blood Cells.

Red blood cells may regulate tissue circulation and O-2 delivery by releasing the vasodilator ATP in response to hypoxia. When released extracellularly, ATP is rapidly degraded to ADP in the circulation by ectonucleotidases. In this study, we show that ADP acting on P2Y(13) receptors on red blood cells serves as a negative feedback pathway for the inhibition of ATP release. mRNA of the ADP recepto

Perchlorate stimulates insulin secretion by shifting the gating of L-type Ca2+ currents in mouse pancreatic B-cells towards negative potentials

The effects of the chaotrophic anion perchlorate (ClO4-) on glucose-induced electrical activity, exocytosis and ion channel activity in mouse pancreatic B-cells were investigated by patch-clamp recordings and capacitance measurements. ClO4- stimulated glucose-induced electrical activity and increased the action potential frequency by 70% whilst not affecting the membrane potential when applied in
