Exploring the nature of Information Systems Development Methodology: A Synthesized View Based on a Literature Review

New Information Systems Development Methodologies (ISDMs) are suggested in the belief that their deployment would be beneficial to consultants in their work. A large number of ISDMs already exist but their value has been questioned and at the same time new methodologies continue to be introduced in an attempt to support and improve the practice of information systems development work. What is not

Cysteinyl leukotriene receptor expression pattern affects migration of breast cancer cells and survival of breast cancer patients.

The fact that breast cancer patients with local or distal dissemination exhibit decreased survival, promotes a search for novel mechanisms to suppress such tumor progression. Here we have determined the expression of pro-inflammatory cysteinyl leukotriene receptors (CysLTRs) in breast tumor tissue and their signaling effect on breast cancer cell functions related to tumor progression. Patients wit

T-cell recruitment to the intestinal mucosa.

The intestinal epithelium and underlying lamina propria contains large numbers of T cells that play an important role in maintaining intestinal homeostasis and defense against intestinal pathogens. Recent years have seen several significant advances in our understanding of the mechanisms regulating T-cell localization to the intestinal mucosa. For instance, we now know that the small intestine 'im

Primary and secondary capture of platelets onto inflamed femoral artery endothelium is dependent on P-selectin and PSGL-1.

Platelets constitute a key role in vascular injuries, however, the detailed mechanisms behind platelet-endothelial cell and platelet-leukocyte interactions in the femoral artery are not yet fully elucidated. We used intravital fluorescence microscopy of the femoral artery in C57BL/6 mice to study primary and secondary capture of platelets onto endothelial cells as well as onto adherent platelets a

A new paradigm for the in vitro simulation of sideways fall loading of the proximal femur

Although the direction of loads applied to the proximal human femur is unpredictable during sideways fall, most in vitro and numerical simulations refer to a single loading condition (15° internal rotation; 10° adduction), which has been anecdotally suggested in the 1950s. The aim of the present study was to improve in vitro simulations of sideways falls on the proximal femur. An in vitro setup w

Evolution of P-wave morphology in healthy individuals: a 3-year follow-up study.

BACKGROUND: Orthogonal P-wave morphology in healthy men and women has been described using unfiltered signal-averaged technique and holds information on interatrial conduction. The stability of P-wave morphology in healthy subjects over time is not fully known. METHODS: Sixty-seven healthy volunteers were investigated (29 males, aged 63 +/- 14 years, 48 females, 60 +/- 13 years). Orthogonal lead d

Coagulation Systems of Invertebrates and Vertebrates and Their Roles in Innate Immunity: The Same Side of Two Coins?

Bacterial infections represent a serious health care problem, and all multicellular organisms have developed defense mechanisms to eliminate pathogens that enter the host via different paths including wounds. Many invertebrates have an open circulatory system, and effective coagulation systems are in place to ensure fast and efficient closure of wounds. It was proposed early on that coagulation sy

Identification of a novel and myeloid specific role of the leukemia-associated fusion protein DEK-NUP214 leading to increased protein synthesis.

The t(6;9)(p22;q34) chromosomal translocation is found in a subset of patients with acute myeloid leukemia (AML). The translocation results in a fusion between the nuclear phosphoprotein DEK and the nucleoporin NUP214 (previously CAN). The mechanism by which the fusion protein DEK-NUP214 contributes to leukemia development has not been identified, and disruptions of normal cellular functions by DE

Head-to-head comparison between Actigraph 7164 and GT1M accelerometers in adolescents.

We compared, head-to-head, the old generation Actigraph model 7164 with the new generation Actigraph GT1M accelerometer. A total of 15 randomly selected teenagers (eight girls and seven boys) were investigated. They performed a treadmill test wearing the two kinds of accelerometers around the waist simultaneously. The treadmill test consisted of three different levels of speed 4, 6 and 8 km h(-1)

Paediatric robotic surgery in clinical practice: a cost analysis.

BACKGROUND: Since 2006 we have used robotic assistance when performing minimally invasive laparoscopic fundoplications in children. We compared the costs of robotic surgery with the costs for open and laparoscopic surgery to test our hypothesis that the increased costs of the new technology are acceptable. METHOD: Costs were calculated using the regional hospital prices for our first 14 fundoplica

Standard protocol for assessment of colon cancer improves the quality of pathology.

Aim: Tumour stage is the most important prognostic factor in colon cancer. The aim of this study was to examine the impact on the quality of pathology by the use of a standardized PAD protocol. Method: A standardized PAD protocol for colorectal cancer was developed and all patients subjected to colon resection due to adenocarcinomas between 2004 and 2006 were analyzed concerning lymph node status,

Ethanol reduces rCBF activation of left dorsolateral prefrontal cortex during a verbal fluency task

Measurements of regional cerebral blood flow were made in 20 healthy young male subjects during sobriety and inebriation (0.06 % blood alcohol) during rest and during performance of a word fluency test. Word production was decreased during inebriation. The activation within the frontotemporal part of the left dorsolateral prefrontal cortex was preserved during intoxication. During inebriation no a

Adopting a child with cleft lip and palate: A study of parents' experiences.

Abstract Adoption of Chinese children with cleft lip and palate (CLP) has become increasingly more common in Sweden. The aim of this study was to examine parents' experience when adopting a child with CLP. Since 2008, 34 adopted children with CLP have been treated in our department. A questionnaire was sent to 33 of the families and 30 of them answered (91%). The parents had queued from 1 month to

Clinical trial design in haemophilia.

Summary: Progress in the evidence-based care of haemophilia A and B worldwide has been historically challenged by the dearth of evaluable outcome data, including but not limited to the safety and effectiveness of therapeutic interventions. These challenges are partially rooted in the inherent difficulty of conducting prospective clinical trials and observational studies with statistically meaningf
