BACKGROUND AND PURPOSE Neurogenesis can arise from neural stem/progenitor cells of the subventricular zone after strokes involving both the cortex and striatum. However, it is controversial whether all types of stroke and strokes of different sizes activate neurogenesis from the subventricular zone niche. In contrast with cortical/striatal strokes, repair and remodeling after mild cortical stro...

[1] Between June 2003 and September 2005, 20 broadband, three-component seismometers were deployed along the MacKenzie-Liard Highway in Canada’s Northwest Territories as part of the joint Lithoprobe-IRIS Canada Northwest Experiment (CANOE). These stations traverse a paleo-Proterozoic suture and subduction zone that has been previously documented to mantle depths using seismic reflection profili...

BACKGROUND All of previous biomechanical studies on meniscal repair have examined the meniscus itself without synovial membrane and capsule, although in the clinical setting, the meniscal repair is generally performed including capsule. Therefore, biomechanical properties of transcapsular meniscal repair are unclear. Thus, this study aimed to clarify the biomechanical properties of transcapsula...

Scleral fixation of intraocular lenses (IOLs) can be performed under the protection of a scleral flap. A variation of this technique uses a scleral tunnel for suture fixation to the eye. Passage of a double-armed suture through the roof of the scleral tunnel with subsequent retrieval of the suture ends through the external incision for tying facilitates scleral fixation. This modification offer...

BACKGROUND Coated polyglactin 910 suture with triclosan was developed recently in order to imbue the parent suture, coated polyglactin 910, with antibacterial activity against the most common organisms that cause surgical site infections (SSI). Because such alterations could alter the physical properties of the suture, this study sought to compare the intraoperative handling and wound healing c...

This study investigates petrology and major, minor, and rare earth elements ‎geochemistry of ‎East Iranian Eocene–Oligocene volcanic rocks in Sistan suture ‎zone, to examine their ‎petrogenesis and magma evolution. The volcanic rocks include andesite, trachy-andesite, dacite ‎and rhyolite. ‎These calc-alkaline rocks of high-K series are enriched in Large ‎Ion Lithophile ‎Elements of Rb and Ba a...

To improve the functional outcomes of intrasynovial tendon suture, prior experiments evaluated individual technical modifications used in the repair process. Few studies, however, have assessed the combinatorial effects of those suture modifications in an integrated biomechanical manner, including a sample size sufficient to make definitive observations on repair technique. Two hundred fifty-si...

The Lapland–Kola Orogen (LKO; former Kola craton) in the northern Fennoscandian Shield comprises a collage of partially reworked late Archaean terranes with intervening belts of Palaeoproterozoic juvenile crust including the classic Lapland Granulite Terrane. Rifting of Archaean crust began at c 2.5–2.4 Ga as attested by layered mafic and anorthositic intrusions developed throughout the norther...

This study evaluated the impact of a new half hitch loop suture configuration on flexor tendon repair mechanics. Cadaver canine flexor digitorum profundus tendons were repaired with 4- or 8-strands, 4-0 or 3-0 suture, with and without half hitch loops. An additional group underwent repair with half hitch loops but without the terminal knot. Half hitch loops improved the strength of 8-strand rep...

In the Southern São Francisco Craton near Itapecerica (Minas Gerais – Brazil) occurs a supracrustal succession of rocks, varying from bottom to top by quartzite, graphite schist, khondalitic paragneiss and banded iron formation whose protoliths are oceanic basin with ages in context Rhyacian-Orosirian orogeny. Amphibolite metaultramafic bodies occur associated this succession. Mineralogical tex...
