Whole-body ischemia and reperfusion due to cardiac arrest and subsequent return of spontaneous circulation constitute post-cardiac arrest syndrome (PCAS), which consists of four syndromes including systemic ischemia/reperfusion responses and post-cardiac arrest brain injury. The major pathophysiologies underlying systemic ischemia/reperfusion responses are systemic inflammatory response syndrome and increased coagulation, leading to disseminated intravascular coagulation (DIC), which clinically manifests as obstruction of microcirculation and multiple organ dysfunction...

Andrew G Chapple, Marina Vannucci, Peter F Thall, Steven Lin
A variable selection procedure is developed for a semi-competing risks regression model with three hazard functions that uses spike-and-slab priors and stochastic search variable selection algorithms for posterior inference. A rule is devised for choosing the threshold on the marginal posterior probability of variable inclusion based on the Deviance Information Criterion (DIC) that is examined in a simulation study. The method is applied to data from esophageal cancer patients from the MD Anderson Cancer Center, Houston, TX, where the most important covariates are selected in each of the hazards of effusion, death before effusion, and death after effusion...

Acute promyelocytic leukemia (APL) is a hyper-acute illness and presents with profound cytopenias in most patients and disseminated intravascular coagulation (DIC). Excellent treatment options are now available with drugs such as all-trans retinoic acid (ATRA), arsenic trioxide (ATO), anthracyclines and cytarabine. The outcome in APL has improved tremendously in the last 50years due to better understanding of the disease, development of effective targeted agents and improvement in supportive care. Carefully selected groups of patients treated in large multi-center trials on a protocol and in experienced centers have shown survival rates in excess of 85%...

BACKGROUND AND OBJECTIVE: Pimples (acne) are small skin lesions or inflammations of the skin. The most common factor causing acne is the hormonal changes that occur during adolescent and teenage years. Antibiotics are becoming less effective in the treatment of pimples due to increasing concerns of antibiotic resistance. This study was therefore carried out to characterize the isolates from the pimples of Covenant University Students and to determine their antibiotics sensitivity pattern...

Aims: Clinical studies suggest beneficial effects of renin-angiotensin system blockade for prevention of left ventricular (LV) dysfunction after chemotherapy. However, the efficacy of this strategy as primary prevention has been poorly studied. This study aimed at identifying the pathophysiological mechanisms by which mineralocorticoid receptor antagonism (MRA) or angiotensin converting enzyme inhibition (ACEi) provide protection against doxorubicin-induced cardiotoxicity (DIC) in mouse models of acute and chronic toxicity...

Multicellular tubes, fundamental units of all internal organs, are composed of polarized epithelial or endothelial cells, with apical membranes lining the lumen and basolateral membranes contacting each other and/or the extracellular matrix. How this distinctive membrane asymmetry is established and maintained during organ morphogenesis is still an unresolved question of cell biology. This protocol describes the C. elegans intestine as a model for the analysis of polarized membrane biogenesis during tube morphogenesis, with emphasis on apical membrane and lumen biogenesis...

Drosophila neuromuscular junction (NMJ) is an excellent model system to study glutamatergic synaptic transmission. We describe the technique of focal macropatch recordings of synaptic currents from visualized boutons at the Drosophila larval NMJ. This technique requires customized fabrication of recording micropipettes, as well as a compound microscope equipped with a high magnification, long-distance water immersion objective, differential interference contrast (DIC) optics, and a fluorescent attachment. The recording electrode is positioned on the top of a selected synaptic bouton visualized with DIC optics, epi-fluorescence, or both...

During the course of infection with a hemorrhagic fever virus (HFV), the checks and balances associated with normal coagulation are perturbed resulting in hemorrhage in severe cases and, in some patients, disseminated intravascular coagulopathy (DIC). While many HFVs have animal models that permit the analyses of systemic coagulopathy, animal infection models do not exist for all HFVs and moreover do not always recapitulate the pathology observed in human tissues. Furthermore, molecular analyses of how coagulation is affected are not always straightforward or practical when using ex-vivo animal-derived samples, thus reinforcing the importance of cell culture studies...

Restrictive transfusion is the most common and appropriate treatment for patients with bleeding disorders because it is associated with better prognosis. However, hematologists are not familiar with the indication for and effect of using fresh frozen plasma (FFP) for transfusions, which has been inappropriately used to date. FFP should not be transfused for preventing bleeding or improving coagulation test results (i.e., PT and APTT). Instead, FFP transfusion should be performed to manage hemostasis, based on the fibrinogen levels of <150 mg/dl in patients' plasmas...

"Fibrin is insoluble in blood" is the most important concept to accept the coagulation system. Essentially, blood coagulation is a process to convert blood from soluble to insoluble. Fibrinolysis is another process to convert insoluble protein to soluble protein again. The blood coagulation cascade requires calcium ion and efficiently acts on platelet phospholipid membranes. On the other hand, the fibrinolysis system efficiently acts on fibrin. Unlike other vitamin K-dependent coagulation factors, thrombin can be released from the coagulation site to the systemic circulation and has multiple biological effects regulated through thrombin receptors...

In the present study, we designed and synthesized a hydrogelator comprised of ibuprofen (IPF) and GFFY peptide linked through a cleavable ester bond. We found that the synthesized hydrogelator could spontaneously self-assemble into a hydrogel under a heating-cooling process. When the hydrogel was acted upon by an esterase, IPF was released in a sustained manner. Moreover, the hydrogel had significantly elevated anti-inflammatory efficacy, compared with IPF, in RAW264.7 macrophages. The hydrogel showed good cytocompatibility, as well as excellent ocular biocompatibility when instilled topically...

BACKGROUND: Reported tuberculosis (TB) incidence globally continues to be heavily influenced by expert opinion of case detection rates and ecological estimates of disease duration. Both approaches are recognised as having substantial variability and inaccuracy, leading to uncertainty in true TB incidence and other such derived statistics. METHODS: We developed Bayesian binomial mixture geospatial models to estimate TB incidence and case detection rate (CDR) in Ethiopia...

Many studies have measured the global compressive properties of tissue engineered (TE) cartilage grown on porous scaffolds. Such scaffolds are known to exhibit strain softening due to local buckling under loading. As matrix is deposited onto these scaffolds, the global compressive properties increase. However the relationship between the amount and distribution of matrix in the scaffold and local buckling is unknown. To address this knowledge gap, we studied how local strain and construct buckling in human TE constructs changes over culture times and GAG content...

BACKGROUND: Hyperleukocytosis in acute leukemia is associated with higher early mortality due to the major complications of leukostasis, tumor lysis syndrome (TLS), and disseminated intravascular coagulopathy (DIC). Leukapheresis remains an important modality for the management of patients with acute leukemia and hyperleukocytosis. However, the role of leukapheresis in early mortality is controversial. This study sought to evaluate the prognostic impact of leukapheresis and its beneficial effects on TLS and DIC...
