PURPOSE: Although some studies suggest a strong link between retinal vessel oxygenation and damage to the retinal nerve fiber layer (RNFL) seen in glaucoma, it has yet to be conclusively proven. This study compares intraocular retinal oximetry in glaucomatous eyes displaying asymmetrically affected hemifields across different subgroups of glaucoma, namely primary angle closure glaucoma (PACG), primary open-angle glaucoma (POAG), and normal tension glaucoma (NTG). METHODS: In this prospective cross-sectional study, 99 patients (PACG, n=28; POAG, n=37; NTG, n=34) underwent retinal oxygenation and vessel caliber measurements using the Oxymap T1 Retinal Oximeter, Cirrus optical coherence tomography, and Humphrey visual field testing...

Transcaval access has been used successfully for over 200 transcatheter aortic valve replacements, large-bore percutaneous left ventricular assist devices, and thoracic endovascular aortic aneurysm repairs. This review teaches how to plan transcaval access and closure based on computed tomography. The main planning goals are to: 1) identify calcium-free crossing targets in the abdominal aorta along with optimal fluoroscopic projection angles and level with respect to lumbar vertebrae; 2) identify obstacles such as interposed bowel or pedunculated aortic atheroma; 3) plan covered stent bailout; and 4) identify jeopardized vascular branches such as renal arteries that might be obstructed by bailout covered stents if employed...

BACKGROUND: Most skin defects that require reconstruction with a local skin flap have a circular- or oval-shaped pattern. The majority of the skin flaps are planned in an angled shape. Therefore, it may be necessary to modify the shape of the defect or the distal flap border to minimize tissue distortion. We have designed a circular-shaped advancement flap to be compatible with the circular defect. METHODS: Eighteen cases of reconstruction of skin defects in the face, chest wall, hand and buttock area were performed using the omega advancement flap between 2010 and 2014...

Primary angle-closure glaucoma (PACG) is a common cause of blindness. Angle closure is a fundamental pathologic process in PAGC. With the development of imaging devices for the anterior segment of the eye, a better understanding of the pathogenesis of angle closure has been reached. Aside from pupillary block and plateau iris, multiple-mechanisms are more common contributors for closure of the angle such as choroidal thickness and uveal expansion, which may be responsible for the presenting features of PACG...

The zygoma, or jugum, is a cranial element that was present in Mesozoic tetrapods, well before the appearance of mammals. Although as an entity the zygoma is a primitive retention among mammals, it has assumed myriad configurations as this group diversified. As the zygoma is located at the intersection of the visual, respiratory, and masticatory apparatuses, it is potentially of great importance in systematic, phylogenetic, and functional studies focused on this region. For example, the facial component of the zygoma and its contribution to a postorbital bar (POB) appear to be relevant to the systematics of a number of mammalian subclades, and the formation of a bony postorbital septum (POS) that separates the orbit from the infratemporal fossa is unique to, and thus potentially phylogenetically significant for uniting anthropoid primates, while the zygoma itself appears to serve to resist tension and bending forces during mastication...

Owing to their intense near infrared absorption and emission properties, to the ability to photogenerate singlet oxygen, or to act as photoacoustic imaging agents within the optical window of tissue, bacteriochlorins (2,3,12,13-tetrahydroporphyrins) promise to be of utility in many biomedical and technical applications. The ability to fine-tune the electronic properties of synthetic bacteriochlorins is important for these purposes. In this vein, we report the synthesis, structure determination, optical properties, and theoretical analysis of the electronic structure of a family of expanded bacteriochlorin analogues...

In this work, polycaprolactone (PCL) was used as a basic polymer for electrospinning of random and aligned nanofiber matrices. Our aim was to develop a biocompatible substrate for ophthalmological application to improve wound closure in defects of the cornea as replacement for human amniotic membrane. We investigated whether blending the hydrophobic PCL with poly (glycerol sebacate) (PGS) or chitosan (CHI) improves the biocompatibility of the matrices for cell expansion. Human corneal epithelial cells (HCEp) and human corneal keratocytes (HCK) were used for in vitro biocompatibility studies...
