PURPOSE Intra-articular knee injections are commonly performed in clinical practice for treating various knee joint disorders such as osteoarthritis and rheumatoid arthritis. When selecting the portal for injection, not only intra-articular needle accuracy but also procedural pain should be taken into consideration. The purpose of this study was to determine whether injection through anterolate...

Portal hypertension is commonly due to obstruction to portal blood flow either within the liver as in cirrhosis, or within the portal vein, as from thrombosis. In recent years, however, reports have multiplied of portal hypertension in the absence of both intrahepatic and extrahepatic obstruction (Rousselot, 1940; Whipple, 1945; Hallenbeck and Shocket, 1957; Tisdale, Klatstin, and Glenn, 1959; ...

DNA packaging in tailed bacteriophages and other viruses requires assembly of a complex molecular machine at a specific vertex of the procapsid. This machine is composed of the portal protein that provides a tunnel for DNA entry, an ATPase that fuels DNA translocation (large terminase subunit), and most frequently, a small terminase subunit. Here we characterized the interaction between the ter...

HANSON, KENNETH M., AND PAUL C. JOHNSON. 4kzzl control of hepatic arterial and portal uenous jaw in the dog. Am. J. Physiol. 211(3): 712-720. I g66.-Hemodynamic studies were made in over IOO experiments on the denervated, autoperfused, dog liver in situ. Electromagnetic flowmeters were used. Data\ are given on pressure-flow relationships in both vascular circuits, with and without simultaneous ...

BACKGROUND Portal vein gas is an ominous radiological sign, which indicates a serious gastrointestinal problem in the majority of patients. Many causes have been identified and the most important was bowel ischemia and mesenteric vascular accident. The presentation of patients is varied and the diagnosis of the underlying problem depends mainly on the radiological findings and clinical signs. T...

Umbilical and supraumbilical catheter insertion is a common procedure performed in the NICU. It is a safe and usually easy procedure devoid of serious mishaps, morbidity and mortality. Complications such as hemorrhage, infection, hernia, evisceration, omphalitis, portal vein thrombosis and portal hypertension may occur after umbilical catheter insertion. Other uncommon and rare complications re...

An experimental model of cirrhosis was developed in the rat to assess the effect of disease and pharmacological manipulation on blood flow, shunting and portal pressure. With progression in the severity of histological cirrhosis there was a steady fall in effective liver blood flow as measured with radioisotope labelled colloid. This corresponded to a rise in portal pressure and shunting with a...

Intrahepatic portal hypertension accounts for most of the morbidity and mortality encountered in patients with liver cirrhosis, due to increased portal inflow and intrahepatic vascular resistance. Most treatments have focused only on portal inflow or vascular resistance. However, miRNA multitarget regulation therapy may potentially intervene in these two processes for therapeutic benefit in cir...

This paper will discuss two of the major Grid portal solutions, the Open Grid Computing Environments Collaboratory (OGCE) and GridPortlets, both of which provide basic tools that portal developers can use to interact with Grid middleware when designing their own custom or application specific Grid portals. We investigate and compare what each of these packages provides, discuss their advantages...
