We assessed the feasibility, accuracy, and safety of securing site-selective brain biopsy specimens by using a real-time CT-guided stereotactic navigation system through a mini-burr hole in the skulls of two dogs. Two beagle dogs each underwent two biopsy procedures. Our results indicated that the navigation system was accurate, safe, fast, and reliable for performing real-time brain biopsy in ...

Scoparia dulcis Linn. (SD) is a perennial herb that has been well studied for its antioxidant, anti-inflammatory, antidiabetic, and hepatoprotective effects. However, scientific information on SD regarding the neuropharmacological effect is limited. This study evaluated the sedative and hypnotic effect of the ethanolic extract of whole plants of Scoparia dulcis (EESD). For this purpose, the who...

Bald patches are magnetic topologies in which the magnetic field is concave up over part of a photospheric polarity inversion line. A bald patch topology is believed to be the essential ingredient for filament channels and is often found in extrapolations of the observed photospheric field. Using an analytic source-surface model to calculate the magnetic topology of a small bipolar region embed...

Background: A macular hole is a full-thickness defect of retinal tissue involving the anatomic fovea, thereby affecting central visual acuity. Pars plana vitrectomy and gas tamponade is a recognised modality of treatment for macular hole.Larger holes are more likely to remain open after repair and late reopening after an initially closed macular hole is seen in macular holes larger than 400 μm....

Black hole production in high-energy collisions is briefly surveyed. Included is a summary of recent developments and open problems relevant to collider (LHC) production, as well as of some theoretical issues pointing towards fundamental principles of quantum gravity.

in this study the synthesis of molybdenum oxide nano-whiskers with circular cross-section is performed. in some areas, it was observed that also some whiskers have open tips exhibiting their hollow structures. these whiskers have side dimensions ranging 2-5 μm with an average diameter in the nanometer rang. the structure suggested the vapor-liquid-solid growth mechanism (vls). scanning elect...

An odd hole in a graph is an induced cycle with length greater than 3. In earlier paper (with Sophie Spirkl), solving longstanding open problem, we gave polynomial-time algorithm to test if has hole. We subsequently showed that, for every t , there whether contains of at least . this article, give that finds shortest hole, one exists.
