Targeted brain hypothermia has the potential to prevent cerebral ischemia injury during open heart and neck surgeries or after traumatic head injury. In this study, in vivo experiments were performed to test the performance of a newly developed cooling device in an inexpensive animal model. Rat brain hypothermia was induced by inserting an interstitial cooling device in the rat neck muscle and ...

Head motion is a common cause of technical failure in functional magnetic resonance imaging. A simple visual alignment system has been developed to provide visual feedback to the subject about his or her head position. The subject is able to readjust his or her head position accurately during a study, should motion occur. This sighting system is incorporated into a visor that fits onto the comm...

In the early stages of amyloid formation, heterogeneous populations of oligomeric species are generated, the affinity, specificity, and nature of which may promote, inhibit, or define the course of assembly. Despite the importance of the intermolecular interactions that initiate amyloid assembly, our understanding of these events remains poor. Here, using amyloidogenic and nonamyloidogenic vari...

A scheme for organizing head-mounted displays based primarily on image configuration and secondarily on the display/optics and head-mounted sensor(s) is offered as a way to clarify design and human interface issues. These attributes are linked to field-of-view, image content and device applications. An argument is made for discarding confusing and outdated concepts. This organization of a diver...

in the present study, the antimicrobial tests of patchouli oil were studied by using molecular docking technology and antimicrobial test in vitro. five biological macromolecule enzymes, required by the bacteria in the process of biosynthesis were selected as target molecules. five antibiotics benzylpenicillin, sulfadiazine, trimethoprim, rifampicin and ciprofloxacin, which are generally acknowle...

the antidiuretic effect of arginine vasopressin (avp) is mediated by the vasopressin v2 receptor. the docking study of avp as a ligand to v2 receptor helps in identifying important amino acid residues that might be involved in avp binding for predicting the lowest free energy state of the protein complex. whereas previous researchers were not able to detect the exact site of the ligand-receptor...

We describe a low-cost, small, remotely triggerable LED device for wireless control of transcranial optical stimulation of cortical neurons, for use in freely moving mice. The device is easily mountable on the head of a mouse with a high-polymer block. Using the Thy1-ChR2-YFP transgenic mice, we demonstrate that the device is capable of remotely triggering muscle twitches upon activation of the...

objective(s): recently we reported that the soybean 15-lipoxygenase (slo) inhibitory activity of pyrimido[4,5-b][l,4]benzothiazines largely depends on the orientation of sulfur atom of thiazine core towards feiii-oh in the active site pocket of the enzyme with subsequent oxidation of sulfur to sulfoxide. in this paper the results of a comparative study on the slo inhibitory activities of the me...

background: luxi is a component of the quorum sensing signaling pathway in vibrio fischeri responsible for the inducer synthesis that is essential for bioluminescence. methods: homology modeling of luxi was carried out using phyre2 and refined with the galaxyweb server. five models were generated and evaluated by errat, anolea, qmean6, and procheck. results: five refined models were generated b...
