Ciguatoxins are produced by toxic benthic dinoflagellates and cause ciguatera fish poisoning worldwide, but the toxic effects on developing marine fish have not been well investigated. The Pacific ciguatoxin (P-CTX-1), is a potent sodium channel agonist, which is one of the most toxic members among all CTXs. This study evaluated the toxic effects of microinjecting purified Pacific ciguatoxin-1 (P-CTX-1) on embryonic development of marine medaka Oryzias melastigma. A lower 96h-LD50 value was estimated for eleuthero-embryos (1...

NF-κB is a critical transcription factor that plays an important role in mediating inflammation, the immune response, and cell proliferation. The activation of NF-κB leads to an enhancement of proinflammatory mediator expression, which is implicated in the pathogenesis of a variety of diseases. Therefore, methods that allow the intracellular tracking of NF-κB are particularly attractive as they can provide information regarding the pathways or stimulation responses that are involved in the activation of NF-κB...

Low dose CT (LDCT) for lung cancer screening is an evidence-based, guideline recommended, and Medicare approved test but uptake requires further study. We therefore conducted patient and provider surveys to elucidate factors associated with utilization. Patients referred for LDCT at an academic medical center were questioned about their attitudes, knowledge, and beliefs on lung cancer screening. Adherent patients were defined as those who met screening eligibility criteria and completed a LDCT. Referring primary care providers within this same medical system were surveyed in parallel about their practice patterns, attitudes, knowledge and beliefs about screening...

The human farnesyl pyrophosphate synthase (hFPPS), a key regulatory enzyme in the mevalonate pathway, catalyzes the biosynthesis of the C-15 isoprenoid farnesyl pyrophosphate (FPP). FPP plays a crucial role in the post-translational prenylation of small GTPases that perform a plethora of cellular functions. Although hFPPS is a well-established therapeutic target for lytic bone diseases, the currently available bisphosphonate drugs exhibit poor cellular uptake and distribution into non-skeletal tissues. Recent drug discovery efforts have focused primarily on allosteric inhibition of hFPPS and the discovery of non-bisphosphonate drugs for potentially treating non-skeletal diseases...

The current review will attempt to describe the important lessons learned from published randomized controlled trials (RCT) comparing water immersion (WI) or water exchange (WE) techniques with gas insufflation colonoscopy. Air insufflation (AI) to distend the colon to permit visualization and passage through the lumen was developed for diagnostic colonoscopy. When screening colonoscopy was adopted, the same AI method was used. Interval cancers, diagnosed within 3 to 5 years after an index screening colonoscopy, appeared to be linked to low adenoma detection rate (ADR)...

Myo-inositol (MI), the precursor of the second messenger phosphoinositide (PI), mediates multiple cellular events. Rat islets exhibit active transport of MI, though the mechanism involved remains elusive. Here, we report, for the first time, the expression of sodium/myo-inositol cotransporter 1 (SMIT1) in rat islets and specifically, β-cells. Genetic or pharmacological inhibition of SMIT impaired glucose-stimulated insulin secretion by INS-1E cells, probably via down-regulation of PI signaling. Additionally, we found that SMIT1 expression in INS-1E cells and isolated islets was augmented by acute high-glucose exposure and reduced in chronic hyperglycemia conditions...
