As in many other methods that have integrated nanoparticles (NPs), the chemical nose/tongue strategy has also progressed greatly since the entrance of NPs into this field. The fascinating tunable physicochemical properties of NPs have made them powerful candidates for array-based sensing platforms and have enabled the development of real-time, sensitive and portable systems that are able to target complex mixtures of analytes. In particular, the unique optical properties of NPs have a key role in providing promising array-based sensing approaches...

Stroke, as the second most common cause of death, imposes a great financial burden on both the individual and society. Mesenchymal stem cells from rodents have demonstrated efficacy in experimental animal models of stroke due to enhanced neurological recovery. Since FGF1 (fibroblast growth factor 1) displays neuroprotective properties, for the first time, we investigated the effect of acute intravenous administration of FGF1 gene transfected adipose-derived mesenchymal stem cell (AD-MSC(FGF1)) on transient experimental ischemic stroke in rats...

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive malignancy with a very poor prognosis, and excessive resistance to chemotherapy. MicroRNAs have been shown to play important roles in PDAC oncogenesis as they can act as both oncogenes and tumor suppressor molecules. Altered expression of specific microRNAs in PDAC has diagnostic and prognostic implications. There is growing body of evidence showing the important role of miR-486-5p and miR-938 for discrimination of PDAC patients from healthy subjects and those with chronic pancreatitis...

There are reports indicating that diuretics including chlorothiazide, furosemide, ethacrynic acid, amiloride and bumetanide can have anticonvulsant properties. Intracellular acidification appears to be a mechanism for the anticonvulsant action of some diuretics. This study was conducted to investigate whether or not triamterene, a K(+)-sparing diuretic, can generate protection against seizures induced by intravenous or intraperitoneal pentylenetetrazole (PTZ) models. And to see if, triamterene can withstand maximal electroshock seizure (MES) in mice...

A beam shaping technique that rearranges the beam for improving the beam symmetry and power density of a ten-bar high power diode laser stack is simulated considering a stripe mirror plate and a V-Stack mirror in the beam shaping system. In this technique, the beam of a high power diode laser stack is effectively coupled into a standard 550 μm core diameter and a NA=0.22 fiber. By this technique, compactness, higher efficiency, and lower cost production of the diode are possible.

Although lithium is still a mainstay in the treatment of bipolar disorder, its underlying mechanisms of action have not been completely elucidated. Several studies have shown that lithium can also modulate seizure susceptibility in a variety of models. In the present study, using a model of clonic seizures induced with pentylenetetrazole (PTZ) in male Swiss mice, we investigated whether there is any interaction between lithium and either calcium channel blockers (CCBs: nifedipine, verapamil, and diltiazem) or N-methyl-D-aspartate (NMDA) receptor antagonists (ketamine and MK-801) in modulating seizure threshold...
