Predictive markers for tamoxifen response in primary breast cancer

Popular Abstract in Swedish Bröstcancer är den vanligaste cancersjukdomen hos kvinnor i västvärlden och årligen nydiagnosticeras omkring 7000 patienter, bara i Sverige. Antalet nyinsjuknade ökar för varje år medan dödligheten sjunker och de främsta orsakerna till detta tros vara förbättrad diagnostik via mammografiscreening och nya behandlingsmöjligheter. Bröstcancer behandlas primärt med kirurgi,It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. Tamoxifen is the most well-established endocrine treatment available, inhibiting tumor growth and improving surv

Criminalization of medical error: Who draws the line?

As stakeholders struggle to reconcile calls for accountability and pressures for increased patient safety, criminal prosecution of surgeons and other health-care workers for medical error seems to be on the rise. This paper examines whether legal systems can meaningfully draw a line between acceptable performance and negligence. By questioning essentialist assumptions behind 'crime' or 'negligence

Seasonality extraction by function fitting to time-series of satellite sensor data

A new method for extracting seasonality information from time-series of satellite sensor data is presented. The method is based on nonlinear least squares fits of asymmetric Gaussian model functions to the time-series. The smooth model functions are then used for defining key seasonality parameters, such as the number of growing seasons, the beginning and end of the seasons, and the rates of growt

Förmaksflimmer - ny kunskap ger nya behandlingsmöjligheter

Atrial fibrillation (AF) is the most common cardiac arrhythmia prompting treatment. Advances in our knowledge of the pathophysiology of AF provide the basis for new and improved treatment modalities. Thus, focal excitation and localised impulse conduction defects are possible trigger factors which can be counteracted by focal ablation and pacing synchronisation, respectively. Perpetuation of AF, c

A web-based interactive virtual environment for mobile phone customization

With globalization, more and more companies are becoming multisited. Efficient and timely collaboration and communication among the development team members become critical for product success. This paper proposes a web-based virtual environment for mobile phone customization, named VMPDS (Virtual Mobile Phone Design Space). The features of this system include the combination of web technology and

The Marriage of Ego and Id. Cognitive Integration and its Relation to Mystical Experience

Abstract in UndeterminedThe author suggests a new model for interpretation of mystical experience, based on a fruitful combination of cognitive psychology and depth psychology. Offering a rather wide definition of mystical experience, the author then turns to two basic assumptions—a general systems approach and an organismic-holistic view of development. Hans Loewald's analysis of primary process

Appendiceal abscesses: primary percutaneous drainage and selective interval appendicectomy.

OBJECTIVE: To present our results of non-surgical primary management of appendiceal abscesses using ultrasonic percutaneous drainage under local anaesthesia, and selective interval appendicectomy. DESIGN: Retrospective study. SETTING: University hospital, Sweden. SUBJECTS: 24 patients with appendiceal abscesses 3-12 cm in size. INTERVENTIONS: Primary ultrasonic percutaneous drainage under local an

Synthesis and structural characterisation of novel platinum-based drug candidates with extended functionality by incorporation of bis(diphenylphosphino)ferrocene units as metal chelators

Among the metal-based anticancer drugs, cisplatin (cis-diaminedichloroplatinum(II)) is the most widely used species in therapy. Despite its clinical success, cisplatin still suffers in generating resistance, as well as being highly toxic due to poor selectivity between healthy and sick cells. By molecular design it ought to be possible to generate new cis-platinum compounds with increased selectiv

The Silurian Mulde Event and a scenario for secundo-secundo events

Graphic correlation using graptolites and conodonts provides a high-resolution timescale for correlating from coastal to deep oceanic sections and, thereby, also a detailed record of the sequence of changes during the Mulde Secundo-Secundo Event. That interval includes sedimentary facies otherwise unknown in older Wenlock to early Ludlow strata on Gotland. The identified sequence of changes includ

A new hybrid RHCE gene (CeNR) is responsible for expression of a novel antigen

BACKGROUND: The red blood cells (RBCs) of a patient, known to have the probable DC(W)(e)/D-- phenotype, typed as D(W)- and Rh32- but were unexpectedly agglutinated by an anti-D(W)/Rh32 serum. The reactivity suggested that the RBCs carried a novel antigen and that the molecular background of this DC(W)(e)/D-- phenotype might be different from those reported. The purpose of this study was to determi

Long-term exposure to glucose and lipids inhibits glucose-induced insulin secretion downstream of granule fusion with plasma membrane.

Mouse beta-cells cultured at 15 mmol/l glucose for 72 h had reduced ATP-sensitive K+ (K-ATP) channel activity (-30%), increased voltage-gated Ca2+ currents, higher intracellular free Ca2+ concentration ([Ca-i(2+]) +160%), more exocytosis (monitored by capacitance measurements, +100%), and greater insulin content (+230%) than those cultured at 4.5 mmol/l glucose. However, they released 20% less ins

Quality of life of elderly persons with cancer: a 6-month follow-up

The aim of this study was to investigate possible changes in quality of life (QoL) in elderly persons diagnosed with cancer (65 years and above), in relation to age, contact with the health-care system, activities of daily living, hope, social network and support. The investigation points were at time of diagnosis (baseline), and again 3 and 6 months after the diagnosis. The study also aimed to in
