We propose a simple and effective approach for fingerprint liveness detection based on the wavelet analysis of the finger tip surface texture. Experimental results show that our method can successfully differentiate live finger tips from fake finger tips made of most commonly used material in fingerprint spoofing.

Trehalose, an a,a-diglucoside, induced a rapid blackening and death of shoot tips of Cuseuta reflexa (dodder) cultured in vitro. The onset of toxic symptom was delayed if any of the several sugars which support the in vitro growth of Cuscuta was supplied with trehalose. The rate of trehalose uptake or its accumulation in the tissue was not affected by sugar cofeeding. The levels of total and re...

Purpose : To prevent intraperitoneal bleeding, it is critical that the extrahepatic portal vein should not be punctured during transjugular intrahepatic portosystemic shunt(TIPS). There has, however, been no procedure for defining the anatomic relationship between the hepatic capsule and the portal vein segment before shunt formation. To avoid a possibly catastrophic outcome of extrahepatic por...

BACKGROUND A transjugular intrahepatic portosystemic shunt (TIPS) is the creation of a percutaneous portosystemic anastomosis which is used as an alternative method of surgical portosystemic shunts and endoscopic treatment in the therapy of complications of portal hypertension. The objective of the present work was to summarize experience with TIPS in 100 patients. METHODS AND RESULTS In 1992...

BACKGROUND & AIMS Several randomized controlled trials have compared a transjugular intrahepatic portosystemic shunt (TIPS) with large-volume paracentesis in cirrhotic patients with refractory ascites. Although all agree that TIPS reduces the recurrence rate of ascites, survival is controversial. The aim of this study was to compare the effects of TIPS and large-volume paracentesis in cirrhotic...

OBJECTIVE Although a transjugular intrahepatic portosystemic shunt (TIPS) is commonly placed to manage isolated gastric varices, balloon-occluded retrograde transvenous obliteration (BRTO) has also been used. We compare the long-term outcomes from these procedures based on our institutional experience. MATERIALS AND METHODS We conducted a retrospective review of patients with isolated gastric...

A new cryopreservation method using aluminum cryo-plates was developed for clonally propagated crops. In this method, shoot tips are attached to the cryo-plates and can easily be manipulated for preservation treatments, such as dehydration. The ease of handling, minimal injury to shoot tips, and rapid rates of cooling and warming resulted in high regrowth rates. More than 80% regrowth was obtai...

The single-electrode voltage-clamp technique requires sharp glass-capillary microelectrodes, whose electrical properties often limit the capabilities of the recording system. Here, we describe a rapid and simple way of coating fine microelectrodes with Dricote and Vaseline that improves their performance during voltage-clamp. The coating prevented clogging of the tips, improved the capacitance ...
