Removal of iatrogenic orbital foreign bodies with a 3D model.

Facial foreign body (FB) is common after trauma, but iatrogenic orbital FB is a rare and unexpected complication of facial FB removal surgery. We present the case of a 43-year-old man with a glass FB in his nose. During the operation, this FB broke into two pieces, and the larger one pierced into the left orbit, close to the eyeball.

Remodeled structure and reduced contractile responsiveness of ocular ciliary artery in spontaneously hypertensive rats.

Aim: To investigate the alterations in both structure and contractile responsiveness of ocular ciliary artery (OCA) in spontaneously hypertensive rat (SHR).

Methods: In this experiment, 20-week-old male SHR and Wistar Kyoto rat (WKY) were studied. The heart rate (HR), the blood pressure (BP; the systolic BP and the diastolic BP) of rats with an electronic sphygmomanometer were measured.

Effects of brinzolamide on rabbit ocular blood flow and .

Aim: To investigate if significant improvement of optic disc blood flow (ODBF) occurs after instillation of brinzolamide onto rabbit eyes.

Methods: Testing of bilateral intraocular pressure (IOP) and left ODBF in 10 male rabbits took place every 3h over a 24h period. Brinzolamide (1% ophthalmic solution, two drops at 9:00 and 21:00) was administered to the left eye.

Microstructure, friction and corrosion resistance properties of a Ni-Co-AlO composite coating.

Ni-Co-AlO composite coatings were prepared by pulsed electrodeposition and electrophoresis-electrodeposition on aluminum alloy. The content of AlO particles of the Ni-Co-AlO composite coating prepared by electrophoresis-electrodeposition was significantly higher than the composite coating prepared by pulsed electrodeposition. The composite coating prepared by electrophoresis-electrodeposition exhibited a better anti-wear performance than that prepared by pulsed electrodeposition.

Antimicrobial and antioxidant activities of Flammulina velutipes polysaccharides and polysaccharide-iron(III) complex [corrected].

FVP is polysacchrides obtained from Flammulina velutipes. A polysacchride named FVP2 was isolated from FVP by DEAE cellulose-52 chromatography and Sephadex G-100 size-exclusion chromatography. FVP-Fe and FVP2-Fe were synthesized by neutralization of FeCl carbohydrate solution.

Angiotensin II type 1 receptor blockade suppresses H2O2-induced retinal degeneration in photoreceptor cells.

Exposure to reactive oxygen species (ROS) leads to the development and progression of retinal degenerative diseases. However, the exact mechanisms are not fully understood. In this article, the role of angiotensin II type 1 receptor (AT1R) signaling in H(2)O(2)-induced retinal damage was examined.
