A novel pathway for ratiometric hydrazine sensing in environmental samples and the detection of intracellular viscosity by a mitochondria-targeted fluorescent sensor.

Mass and signal transfer, dispersion of reactive metabolites in living cells, and interactions between biomacromolecules are greatly affected by viscosity inside the cells. It is crucial to accurately determine viscosity for reliable results because of the complexities of live cells. Herein, we introduce a new fluorescence probe based on the cyanobiphenyl and benzothiazolium units.

Postoperative Atrial Fibrillation Reduced by Intraoperative and Postoperative Cell Saver System in Coronary Artery Bypass Graft Surgery.

Objective: Postoperative atrial fibrillation is commonly seen after cardiac surgery. One of the contributing factors is mediastinal shed blood and inflammation. Cell salvage techniques can reduce allogenic blood transfusion and reduce inflammation.

A reversible calix[4]arene armed phenolphthalein based fluorescent probe for the detection of Zn and an application in living cells.

A reversible and easy assembled fluorescent sensor based on calix[4]arene and phenolphthalein (C4P) was developed for selective zinc ion (Zn ) sensing in aqueous samples. The probe C4P demonstrated high selective and sensitive detection towards Zn over other competitive metal ions. Interaction of Zn with a solution of C4P resulted in a considerable increment in emission intensity at 440 nm (λ  = 365 nm) due to the suppression of photoinduced electron transfer (PET) process and the restriction of C=N isomerization.

Anthracene excimer-based "turn on" fluorescent sensor for Cr(3+) and Fe(3+) ions: Its application to living cells.

A novel anthracene based fluorescent probe containing benzothiazole group (BFA) was designed and synthesized. The cation binding properties of BFA were studied in the presence of various cations. Both UV-vis and fluorescence spectroscopic studies indicated that BFA was highly sensitive and selective toward trivalent cations (Cr(3+) and Fe(3+)), while there was no response to monovalent, divalent cations and also Al(3+) ion.

Complete atrioventricular septal defect and pulmonary stenosis diagnosed in a 49-year-old woman after 10 uneventful births.

Atrioventricular septal defects constitute 4% of all congenital cardiac malformations. Patients with complete atrioventricular septal defect rarely survive for decades without surgical treatment. Pulmonary stenosis can provide a delicate balance between the pulmonary and systemic circulations and thereby increase longevity.
