DeepVein Thrombosis FollowingDescemet Stripping Automated Endothelial Keratoplasty Venous thromboembolism is the secondmost commonmedical complication after surgery.1 The risk factors for development of deepvein thrombosis (DVT) include age, obesity, and diabetesmellitus.1Deepvein thrombosis associatedwithophthalmic surgery, specifically vitreoretinal surgery, has been reported.2 Descemet strip...

BACKGROUND Descemet Stripping Automated Endothelial Keratoplasty (DSAEK) allows selective replacement of the endothelium. Post-operative haze and particles can affect the interface quality and, ultimately, visual outcome. In this study, we evaluated DSAEK interface with in vivo laser confocal microscopy (LCM) in order to: (i) correlate interface status with best corrected visual acuity, and (ii...

PURPOSE To use Fourier-domain anterior segment optical coherence tomography (AS-OCT)) to evaluate the main clear corneal incisions (CCIs) in microcoaxial and biaxial cataract surgery, the effects of incision enlargement, and the probable reasons for problematic healing. SETTING Atatürk Training and Research Hospital, 2nd Ophthalmology Department, Ankara, Turkey. DESIGN Cohort study. METHO...

Basierend auf der Detailstruktur der Thylakoidmembran wird ein allgemein gültiger molekularer Mechanismus für den Protonentransport über biologische Membranen vorgeschlagen. Es wird an­ genommen, daß aufgrund einer Redoxreaktion auf der Membranaußenseite eine Umpolarisierung innerhalb der Phospholipidschicht induziert wird, die zu einer Protonentranslokation führt. In diesem Pumpmodell wird die...

The chorda tympani is an important anatomical structure in the tympanic cavity. It may have some anatomic variations. Its anatomic variations are of interest in certain otologic surgical procedures. There are limited reports in the literature about the variations of the chorda tympani. A 49-year-old female patient was refered to our clinic because of conductive hearing loss and tympanic membran...

2015 Ungefär 100 kilo ATP syntetiseras i kroppen varje dag av ATP-syntas, ett sammansatt proteinkomplex med tre aktiva centra. Komplexet sitter förankrat i ett biologiskt membran med hjälp av hydrofob attraktion och består av en roterande och en statisk del. En ATP-molekyl syntetiseras per tredjedels varv. Trots att varje aktivt centrum skulle kunna fungera oberoende av de andra, sparas mycket ...
