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.

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.

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.

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.
View Article and Find Full Text PDFA new available multi-analyte fluorescent sensor based on a bisphenol A-quinoline conjugate (BFQ) was synthesized in two facile steps and was characterized systematically. BFQ exhibited an effectively selective and sensitive recognition toward Zn(2+)and Al(3+) cations in EtOH-H2O (v/v = 9/1) over other cations and F(-) anion in CH3CN over other anions with remarkably enhanced fluorescent intensities. According to the quantum yield (Φ) measurements, BFQ-Zn(2+), BFQ-Al(3+) and BFQ-F(-) complexes showed 16, 22 and 30 times higher Φ values than BFQ, respectively.

We describe an easy and safe way for sternal stenting using conventional sternal steel wires.

A novel colorimetric and fluorometric calix[4]arene probe (CTP) bearing triphenylamine units was synthesized in good yield and characterized by combination of (1)H, (13)C, APT, COSY, FTIR, HRMS, and UV-vis spectral data. Ion-binding studies of CTP were investigated in acetonitrile with a wide range of cations and anions and the recognition process was monitored by luminescence, UV-vis and (1)H NMR spectral changes. CTP exhibited naked eye detection for Hg(2+) ion.

We retrospectively reviewed medical records of patients who needed ECLS at a new congenital heart center in Turkey. Between December 2009 and February 2012, 616 congenital heart operations were performed.

Between December 2009 and February 2012, 616 operations have been performed in 132 newborns (22%), 260 infants (42%), and 224 children/adolescents (36%). Risk adjustment analysis was performed using the risk adjustment in congenital heart surgery (RACHS-1) risk assessment model.

On echocardiogram, there was a mass attached to the tricuspid annulus, in close proximity to the septal leaflet, with dimensions of 16.6 × 12.

Stent implantation has been widely used for primary aortic coarctation as well. The procedure has been shown to be effective with long term follow ups.

For this, the 2,3,4,6,7,10,11 hexahydroxytriphenylene (HHTP) as starting material was synthesized according to known procedure. Moreover, the 2-((2-chloroethylimino)methyl) phenol material was prepared with reaction of salicylaldehyde and 2-chloroethylamine hydrochloride.

Case Report: Critical aortic coarctation and VSD were diagnosed in a neonate, and coarctation angioplasty was successfully performed. Severe cardiac failure developed after this procedure, however, and closure of the VSD was planned.
Background: Epidural steroid injection (ESIs) is one of the treatment modalities for chronic low back pain (CLBP) with various degrees of success.
Aim: We analyzed the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESIs) via a preganglionic approach in patients with foraminal stenosis due to lumbar spinal stenosis and lumbar discogenic pain with radiculopathy.
Materials And Methods: We analyzed the data of 40 patients (February 2008 and April 2009) with the diagnosis of CLBP and treated by fluoroscopically guided TFESIs via a preganglionic approach.
