Capsule endoscope aspiration into the respiratory tract is a rare complication of capsule endoscopy. Despite the potential seriousness of this complication, no accepted methods exist to accurately predict and therefore prevent it. We describe the case of an 85-year-old male who presented for evaluation of iron deficiency anemia. He complained of dysphagia while ingesting a patency capsule, with...

PURPOSE The development of posterior capsule contraction following cataract surgery is caused by the activity of residual lens epithelial cells. Matrix metalloproteinases (MMPs) are a group of proteolytic enzymes, which are essential for cell migration and cell mediated contraction following wound healing. The authors investigated whether inhibiting MMP activity can reduce lens epithelial cell ...

industrial effluents consist many pollutant and heavy metals. bacteria isolated from industrial west water ground may have potential to tolerate heavy metal. in this study we isolate a citrobacter sp. which can resist heavy metal like cu and pb. slurry from industrial west water ground was collected from 22.0663 n, 88.1041 e. the heavy metal content and other parameters of soil were estimated. ...

Recent electrophysiological investigations of the auditory system in primates along with functional neuroimaging studies of auditory perception in humans have suggested there are two pathways arising from the primary auditory cortex. In the primate brain, a 'ventral' pathway is thought to project anteriorly from the primary auditory cortex to prefrontal areas along the superior temporal gyrus w...

We have treated 45 patients (47 ankles) for chronic lateral instability by a new reconstructive procedure. The operation includes lateral shift of the entire lateral capsule-ligament complex and proximal advancement of the talocalcaneal ligament and the inferior extensor retinaculum. We reviewed 39 patients (39 ankles) at a mean of 4.6 years (2 to 7) after operation. There were 29 men and 10 wo...

This paper describes the previously unknown larva of Drusus vinconi Sipahiler, 1992. Information on the morphology of the 5th larval instar is given, and the most important diagnostic features are illustrated. In the context of existing identification keys the larva of Drusus vinconi keys together with Drusus annulatus (Stephens, 1837), Drusus biguttatus (Pictet, 1834), Drusus ingridae Sipahile...

Spinal stenosis is a term that means narrowing of the spinal canal or the nerve root foramina. It is thus divided into central or lateral stenosis. Central stenosis produces compression of the thecal sac: soft tissue (ligamentum flavum and disc) may contribute as much as 40% to this compression. It is more common in males because their spinal canal is smaller at the L3-L5 level. Lateral stenosi...

18 This work describes the morphology of the sperm cell of Maja brachydactyla, with emphasis on 19 localizing actin and tubulin. The spermatozoon of M. brachydactyla is similar in appearance and 20 organization to other brachyuran spermatozoa. The spermatozoon is a globular cell composed of 21 a central acrosome, which is surrounded by a thin layer of cytoplasm, and a cup-shaped nucleus 22 with...

The ultrastructure of lens capsule abnormalities in Alport's syndrome is reported. An anterior lens capsule from a 29-year-old patient with lenticonus who was affected by Alport's syndrome was obtained at the time of surgery. The histopathologic findings showed the thickness of the anterior lens capsule was decreased and there were many vertical capsular dehiscences localized at the inner part ...

BACKGROUND The aim of this study was to determine the ideal point for a ventricular puncture in pterional craniotomies. METHODS Using a circle that had its center around the junction of the columns of the fornix and conforming to the surface of the frontal lobe on an axial computed tomography scan 2.5 cm superior to the lateral orbital roof, we simulated the introduction of a catheter perpend...
