a dog was presented with history of progressive generalized subcutaneous emphysema and exercise intolerance secondary to dog fight. radiographic evaluation confirmed extensive subcutaneous emphysema, pneumomediastinum and pneumoretroperitoneum. surgical exploration revealed cricoid cartilage longitudinal fracture and cricotracheal detachment. the fractured cartilage was sutured and the cricoid ...

purpose: to compare the anatomical results of scleral buckling with or without retinopexy and to assess the effect of retinopexy on outcomes of the operation.  methods: this interventional case series was performed on 22 patients undergoing scleral buckling (segmental or encircling) with or without subretinal fluid drainage and without any type of retinopexy and 33 patients who received transsc...

objective: to determine the sensivity and specifity of ocular ultrasonography in detecting vitreoretinal lesion prior to deep vitrectomy in patients with opaque media. method: the hospital records of patients undergoing deep vitrectomy in a defined period at shiraz khalili hospital were reviewed. sonographic reports given by a sonologist and operation reports given by a vitreoretinal fellowship...

[1] The Nordfjord-Sogn Detachment Zone(NSDZ) is widely cited as one of the primary structures responsible for the exhumation of Norwegian (ultra)high-pressure (UHP) rocks. Here we review data from the considerable volume of research describing this shear zone, and compile a strikeparallel cross section along the NSDZ from the Solund Basin in the south to the Sørøyane UHP domain in the north. Th...

PURPOSE This study aimed to elucidate the degree of biceps anchor displacement that occurs when specific zones of the superior labrum are detached from the glenoid. STUDY DESIGN Descriptive laboratory study. METHODS Twelve cadaveric scapulae with intact labrums were prepared by removing the surrounding musculature with the labrum, biceps anchor, and biceps tendon carefully preserved. Pulley...

BACKGROUND AND PURPOSE Aneurysm embolization is not without risk: numerous technical aspects are considered before, during, and after the procedure. The purpose of this study was to show the position of the detachment zone of a Guglielmi detachable coil (GDC) with respect to the catheter tip for various microcatheters and marker alignments. METHODS Six types of commonly used microcatheters we...

[1] We studied the back azimuth dependence of Ps converted phases at GSN station COR (Corvallis, Oregon) using broadband P receiver functions computed from 602 teleseismic earthquakes. The amplitudes and polarities of the transverse Ps phases are largely two-lobed, which indicates anisotropy with a tilted symmetry axis. A double-peaked Ps conversion at 4.5–6.5 s delay has the moveout of a dippi...

Cerebral neocortex development in mammals requires highly orchestrated events involving proliferation, differentiation, and migration of neural progenitors and neurons. Rapgef2 and Rapgef6 constitute a unique family of guanine nucleotide exchange factors for Rap1 small GTPase, which is known to play crucial roles in migration of postmitotic neurons. We previously reported that conditional knock...
