To determine the normal appearance of the flax and interhemispheric fissure, 200 consecutive normal CT scans were evaluated prospectively. On unenhanced scans, the normal falx is visualized in 90% of patients and therefore interhemispheric hyperdensity alone should not be considered a sign of subarachnoid hemorrhage. The flax is most often (88%) visualized in the posterior part of the interhemi...

Purpose Basement membrane degradation and macrophage aggregation at the optic fissure margins are crucial to optic fissure closure during normal murine eye development. Basement membrane degradation is also an essential step in cancer development, and matrix metalloproteinases (MMPs) play an important role. In this study, we investigated MMP alteration at the degrading basement membrane of opti...

In patients with severe emphysema, bronchoscopic lung volume reduction using one-way valves is a promising therapeutic option to improve lung function and quality of life. The goal of this treatment is to achieve a complete lobar atelectasis. In a significant proportion of patients, this atelectasis cannot be achieved due to interlobar collateral ventilation. This collateral ventilation is gene...

Background: Sealant therapy is the safe and effective way to prevent dental caries in newly erupted teeth. Success of sealant therapy depends on the good isolation, patient corporation and the decrease step for the application of sealant. Aim: Comparative evaluation of marginal microleakage of conventional fissure sealants and self-adhering flowable composites as fissure sealant in permanent te...

PURPOSE The purpose of this in vitro study was to determine the effect of different cleaning methods and the use of post-etching drying agents, as well as the influence of fissure types on the microleakage and penetration ability of fissure sealants. METHODS Ninety extracted human molar teeth were randomly divided into 9 groups of 10 each. The treatment groups were defined by the combination ...

Background and objectives: Anal fissure is a painful wound in the anoderm and distal to dentate line, the chronic fissure leads to hypertrophy and fibrosis. In this study, we compared partial and total sphincterotomy in patients with chronic anal fissure. Methods: In this comparative cohort, 100 patients (52 female and 48 male )mean age 43.34 ± 15.28 year...

OBJECTIVE Surgical approaches to ambient cistern lesions are complex. We investigated the microanatomy of the transtemporal-transchoroidal fissure approach to the ambient cistern with emphasis on exposure of the posterior cerebral artery. METHODS Dissections were performed bilaterally in five silicone-injected cadaveric heads. Critical anatomic distances, specifically with reference to the P2...

Abstract Constraining the mechanisms of normal fault growth is essential for understanding extensional tectonics. Fault kinematics remain debated, mainly because very earliest phase deformation through recent syn-kinematic deposits rarely documented. To understand how underlying structures influence surface faulting, we examined in a 10 ka magmatically resurfaced region Krafla fissure swarm, Ic...

Background: Fissure-in-ano is one of the most common benign anorectal disorders often encountered in surgical outpatient department. Various pharmacological agents and interventions have been tried management fissure ano. In this study we compared medical by topical diltiazem gel with established procedure lateral internal sphincterotomy (LIS) chronic anal fissure. Methods: A total 50 patients ...
