purpose: to evaluate the underlying causes of rhegmatogenous retinal detachment (rrd) in eyes operated for this reasion. methods: out of 1473 patients who underwent retinal detachment surgery, records of 369 patients were randomly selected and evaluated for the types of retinal breaks, the underlying disorders, and location of breaks. results: fifty-two percents of patients were less than 50 ye...

Adhesion and friction are closely related and play a predominant role in many natural processes. From the wall-clinging feet of the gecko to bacteria forming a biofilm, in many cases adhesion is a necessity to survive. The direction in which forces are applied has shown to influence the bond strength of certain systems tremendously and can mean the difference between adhesion and detachment. Th...

AIMS To develop a method to screen antifouling agents against marine bacterial adhesion as a sensitive, rapid and quantitative microplate fluorescent test. METHODS AND RESULTS Our experimental method is based on a natural biofilm formed by mono-incubation of the marine bacterium Pseudoalteromonas sp. D41 in sterile natural sea water in a 96-well polystyrene microplate. The 4'6-diamidino-2-phe...

Cross-contamination in the poultry slaughtering process can lead to thespread of zoonotic bacteria like Salmonellaenterica. Surfaces equiptment may facilitate contamination carcasses due bacterial adherence and transfer. In this study, attachment, proliferation, detachment Salmonella Enteritidis Escherichia coli were comparatively investigated on uncoated silica-coated stainless-steel surfaces....

Exfoliation, which is the detachment of infected epithelial cells, is an innate defense mechanism to prevent bacterial colonization. Indeed, infection with Neisseria gonorrhoeae induced epithelial detachment from an extracellular matrix (ECM) substrate in vitro. Surprisingly, variants of N. gonorrhoeae that bind to human carcinoembryonic antigen-related cell adhesion molecules (CEACAMs) failed ...

Dental implant failure is primarily due to peri-implantitis, a consequence of bacterial penetration causing loosening. Beyond supporting the implant, adhesion gingival tissues surface essential for its role as physical barrier bacteria. Surface nanotextures are widely known affect wettability, protein adsorption, and cellular and/or adhesion. In this report, femtosecond laser (fs-L) was used de...

PURPOSE To evaluate the causes of retinal detachment after silicone oil removal, to define possible risk factors and the anatomical and functional prognosis of this complication. METHODS 112 eyes that underwent silicone oil removal were included. The group of eyes with retinal detachment after oil removal (18/112 eyes, 16.1%) was compared with the group with no postoperative retinal detachmen...

A series of 54 non-myopic aphakic eyes with no signs of posterior vitreous detachment and 63 non-myopic aphakic eyes with various stages of posterior vitreous detachment was followed-up for a period of 6 months to 6 years. Over half of the eyes with no vitreous detachment when first examined developed various stages of posterior vitreous detachment during the follow-up period; in 10 eyes this w...
