Imaging Foreign Bodies: Ingested, Aspirated, and Inserted.
Foreign bodies can gain entrance to the body through several mechanisms, ie, ingestion, aspiration, and purposeful insertion. For each of these common entry mechanisms, this article examines the epidemiology, clinical presentation, anatomic considerations, and key imaging characteristics associated with clinically relevant foreign bodies seen in the emergency department (ED) setting. We detail ...
متن کاملTranslocation of inserted foreign epitopes by a channel-forming protein.
Certain bacterial protein toxins are able to insert themselves into, and at least partially across, lipid bilayer membranes in the absence of any auxiliary proteins, by using unknown mechanisms to overcome the high energy barrier presented by the hydrophobic bilayer core. We have previously shown that one such toxin, colicin Ia, translocates a large, hydrophilic part of itself completely across...
متن کاملA Case of Foreign Body in the Cornea; Removal and Rapid Recovery
Hue Mohun, a Hindu boy, aged 12 years, was brought to the dispensary at Hungpore on the 3rd December, 1871. He had a very thin chip of bamboo accidentally fixed into the cornea of his right eye. The chip had gone through the thickness of the cornea for about a quarter of an inch, and then just protruded into the aqueous humor, but the outer end was not protruding externally. The whole length of...
متن کاملLaparoscopic Removal of a Pancreatic Foreign Body
We present a case report of a laparoscopically retrieved foreign body that migrated into the pancreas. The patient is a 44-year-old man who presented with epigastric pain and was subsequently found by computed tomographic scan to have a foreign body in the head of the pancreas. After attempted endoscopic retrieval, we successfully removed the foreign body laparoscopically, thus avoiding laparot...
متن کاملConformation of membrane-inserted P-glycoprotein
Background The human genome codes for 49 members of the large ABC protein family. Most of them are membrane transporters. The first structures of exporters have been solved in recent years. Although a remarkable achievement, some uncertainty remained with respect to the physiological conformation of the transporter, which seems not to be fully compatible with all biochemical evidence. During cr...
