BACKGROUND: Staurosporine is a therapeutic agent that inhibits tumor cell growth by inducing cell death via intrinsic apoptotic pathways. Our previous studies in clinical settings have suggested that certain subpopulations of patients with acute myeloid leukemia (AML) had poor response to chemotherapy. MATERIALS AND METHODS: The effect of staurosporine on apoptosis and cell cycle distribution in h

Introduction: Although numerous tumour markers are available for periampullary tumours, including pancreatic cancer, their specificity and sensitivity have been questioned.Materials and methods: To assess the diagnostic and prognostic values of tissue polypeptide specific antigen (TPS), carbohydrate antigen 19-9 (CA 19-9), vascular endothelial growth factor (VEGF-A), and carcinoembryonic antigen (

Phosphorylated tyrosine residues in receptor tyrosine kinases serve as binding sites for signal transduction molecules. We have identified two autophosphorylation sites, Tyr-988 and Tyr-1018, in the platelet-derived growth factor (PDGF) alpha-receptor carboxyl-terminal tail, which are involved in binding of phospholipase C-gamma (PLC-gamma). The capacities of the Y988F and Y1018F mutant PDGF alpha

PURPOSE: It is unknown whether childhood cancer and its treatment are associated with sperm DNA damage, which subsequently affects fertility and might be transmitted to the offspring. The aim of this study was to assess DNA fragmentation index (DFI) as an indicator of sperm DNA integrity in childhood cancer survivors (CCS), treatment regimen taken into account.EXPERIMENTAL DESIGN: In 99 CCS and 19

Concurrent testing of the cores in a core-based system- on-chip reduces the test application time but increases the test power consumption. Power models, test architecture design, and scheduling algorithms have been proposed to schedule the tests as concurrently as possible while respecting the power budget. The commonly used global peak power model, with a single value capturing the power dissipa

Background:No large cohort study has examined the risk of endometrial cancer in relation to sun exposure.Methods:A population-based cohort study of 29 508 women who answered a questionnaire in 1990-92, of whom 24 098 responded to a follow-up enquiry in 2000-02. They were followed for an average of 15.5 years.Results:Among the 17 822 postmenopausal women included, 166 cases of endometrial cancer we

Anecdotal evidence suggests that task-shifting or the redistribution of responsibilities from fully-trained surgeons to clinicians with fewer qualifications could become a major component of surgical care delivery in many low-income and middle-income countries (LMICs). Our goal was to summarise the scope of surgical task-shifting in LMICs through a systematic review of the medical literature.

Traumatic brain injury (TBI) is an important health problem, and a leading cause of death in children worldwide. Mitochondrial dysfunction is a critical component of the secondary TBI cascades. The response of mitochondria in the pediatric brain to injury has limited investigation, despite evidence that developing brain's response differs from the adult, especially in diffuse non-impact TBI. We pe

To study whether the incretin effect is involved in adaptively increased insulin secretion in insulin resistance, glucose was infused at a variable rate to match glucose levels after oral glucose (25 mg) in normal anesthetized C57BL/6J female mice or in mice rendered insulin resistant by 8 weeks of high-fat feeding. Insulin response was markedly higher after oral than i.v. glucose in both groups,

The current study aimed to characterize changes in EEG-related measures after noxious stimuli in neonates, and to assess their potential utility as measures of pain and/or discomfort during neonatal intensive care.Seventy-two healthy term infants were investigated: Twenty-eight had a non skin-breaking pin-prick on the heel, randomized to receive either oral glucose (n=16) or water (n=12) before th

Alcohol consumption is associated with squamous cell carcinoma of the esophagus, but little is known about whether alcohol consumption is associated with adenocarcinoma of the esophagus and gastric cancer, which we attempt to clarify in this study. Individuals with alcohol use disorders were identified from the nation-wide Swedish Hospital Discharge Register and Outpatient Register, the Crime Regi

Inhibition of mitochondrial permeability transition (mPT) has emerged as a promising approach for neuroprotection and development of well-tolerated mPT inhibitors with favorable blood-brain barrier penetration is highly warranted. In a recent study, 28 clinically available drugs with a common heterocyclic structure were identified as mPT inhibitors e.g. trifluoperazine, promethazine and nortriptyl

OBJECTIVES: To map by magnetic resonance imaging (MRI) and quantitative MRI (qMRI) concomitant fractures and meniscal injuries, and location and volume of traumatic bone marrow lesions (BMLs) in the acutely anterior cruciate ligament (ACL) injured knee. To relate BML location and volume to cortical depression fractures, meniscal injuries and patient characteristics. METHODS: One hundred and twenty

The main mechanisms of immune defense against Neisseria meningitidis are serum bactericidal activity (SBA) and opsonophagocytosis. Many complement deficiencies, among them acquired partial C3 deficiency due to stabilizing autoantibodies against the alternative pathway C3 convertase (C3 nephritic factors, C3 NeF); increase the risk of meningococcal infection. SBA against meningococci in patients wi

Infiltration of eosinophils into the intestinal mucosa is a typical hallmark of antiparasite immune responses and inflammatory disorders of the intestinal tract, and eosinophils are thought to contribute to these processes by release of their cytotoxic granule content. However, utilizing novel tools to study eosinophils, it has been recognized that eosinophils are constitutively present in the gas

Aim. This article is a report of the development and psychometric testing of the Swedish version of the Clinical Learning Environment, Supervision and Nurse Teacher evaluation scale. Background. To achieve quality assurance, collaboration between the healthcare and nursing systems is a pre-requisite. Therefore, it is important to develop a tool that can measure the quality of clinical education. T
