FLT3 is frequently mutated and overexpressed in acute myelogenous leukemia (AML) and other hematologic malignancies. Although signaling events downstream of FLT3 receptor tyrosine kinase has been studied in depth, molecular mechanisms of how FLT3 expression is regulated at the post-transcriptional level in particular remain elusive. In this study, we investigated the roles of an RNA binding protein MSI2 as a regulator of FLT3 expression. MSI2 and FLT3 are significantly co-regulated in human AML and chronic myelogenous leukemia in blast crisis (BC-CML)...

To date, clinical success of cardiac cell-therapies remains limited. To enhance the cardioreparative properties of stem cells, the concept of lineage-specification through cardiopoietic-guidance has been recently suggested. However, so far, only results from murine studies and from a clinical pilot-trial in chronic heart-failure (CHF) are available, while systematic evidence of its therapeutic-efficacy is still lacking. Importantly, also no data from large animals or for other indications are available. Therefore, we here investigate the therapeutic-efficacy of human cardiopoietic stem cells in the treatment of post-infarction LV-dysfunction using a translational pig-model...

Fragmented and uncoordinated care is the third highest driver of U.S. healthcare costs. Although less than 10% of patients experience uncoordinated care, these patients represent 36% of total healthcare costs; care management interaction makes a significant impact on the utilization of healthcare dollars. A literature search was conducted to construct a model of care coordination for elective surgical procedures by collecting best practices for acute, transitions, and post-acute care periods. A case study was used to demonstrate the model developed...

Intraperitoneal transplantation of hepatocyte microbeads is an attractive option for the management of acute liver failure. Encapsulation of hepatocytes in alginate microbeads supports their function and prevents immune attack of the cells. Establishment of banked cryopreserved hepatocyte microbeads is important for emergency use. The aim of this study was to develop an optimised protocol for cryopreservation of hepatocyte microbeads for clinical transplantation using modified freezing solutions. Four freezing solutions with potential for clinical application were investigated...

The highly acidic gastric environment creates a physiological barrier for using therapeutic drugs in the stomach. While proton pump inhibitors have been widely used for blocking acid-producing enzymes, this approach can cause various adverse effects. Reported herein is a new microdevice, consisting of magnesium-based micromotors which can autonomously and temporally neutralize gastric acid through efficient chemical propulsion in the gastric fluid by rapidly depleting the localized protons. Coating these micromotors with a cargo-containing pH-responsive polymer layer leads to autonomous release of the encapsulated payload upon gastric-acid neutralization by the motors...

A 57-year-old female presenting with acute-onset paraplegia was referred for magnetic resonance imaging (MRI) of cervico-dorsal spine. On MRI, multiple tortuous dilated vessels were noted in the epidural space with long segment cord compression and imaging features of compressive myelopathy. Associated small acute cervico-dorsal epidural hematoma was also noted in the same region. Computed tomography (CT) angiography was performed subsequently which revealed post-ductal coarctation of aorta with multiple arterial collaterals in the chest wall and spinal canal...

Population ageing poses many challenges. Recurrent readmission to hospital by frail older people places a strain on health systems and the individual. Registered nurses with experience in emergency department, ICU and aged care conducted telephone follow-up calls to patients or bereaved family members after an acute hospital admission. During follow-up calls, many patients reported feelings of loneliness and social isolation post-discharge. It was also found that patients may not be aware of support services available in the community...

BACKGROUND: Pathophysiological responses, including cardiovascular complications, often alter with age. Cardioprotective effects of epoxyeicosatrienoic acids (EETs) toward acute myocardial ischemia-reperfusion injury have been well documented. However, biological relevance of EET-evoked cardioprotection in the ageing myocardium remains unknown. EETs are metabolized to less active metabolites by the enzyme soluble epoxide hydrolase (sEH). This study uses permanent occlusion of the left anterior descending artery (LAD) in young and aged sEH null and WT mice to compare cardiac and mitochondrial function following ischemic injury...

The objective of this study was to evaluate the clinical disease, humoral response and viral distribution of recent Porcine rubulavirus (PorPV) isolates in experimentally infected pigs. Four, 6-piglet (5-days old) groups were employed (G1-84, G2-93, G3-147, and G4-T). Three viral strains were used for the experimental infection: the reference strain LPMV-1984 (Michoacán 1984) and two other strains isolated in 2013, one in Queretaro (Qro/93/2013) and the other in Michoacán (Mich/147/2013). Each strain was genetically characterized by amplification and sequencing of the gene encoding hemagglutinin-neuroamidase (HN)...

A leading cause of maternal mortality in the first trimester is hemorrhage due to a ruptured ectopic pregnancy. With the advent of tube salvage surgery, ectopic pregnancies can be removed while ensuring hemostasis and preserving the integrity of the fallopian tube. A major drawback of tube salvage surgery is the significant risk of persistent trophoblastic tissue being left behind. We report a case of a 30year old female who presented to the ED with acute abdomen and hemoperitoneum due to a ruptured ectopic pregnancy...
