Sealing the Leak

Sealing the Leak on Classical NTRU Signatures

Initial attempts to obtain lattice based signatures were closely related to reducing a vector modulo the fundamental parallelepiped of a secret basis (like GGH [9], or NTRUSign [12]). This approach leaked some information on the secret, namely the shape of the parallelepiped, which has been exploited on practical attacks [24]. NTRUSign was an extremely efficient scheme, and thus there has been ...

Pulmonary Capillary Leak Syndrome

Sealing the ducts

The transitional epithelium lining the ducts of various glands such as salivary and mammary glands, and organs such as liver, pancreas, kidney and lung must bear a permeability barrier as they are in direct contact with the hostile environment in the lumen. The barrier function of pancreatic ductal epithelium is essential for preventing the back flux of proteases, lipases and DNAases from the p...

Choledochoscope-assisted percutaneous fibrin glue sealing of bile leak complicating transarterial chemoembolization of hepatocellular carcinoma after liver transplantation.

is recommended for patients with unresectable hepatocellular carcinoma (HCC); however, it is not a risk-free procedure and biloma may occur as a complication [1]. A 45-year-old man, following liver transplantation, presented with recurrent HCC in the caudate lobe, close to the caval vein, and was treated by TACE. Subsequently, the patient was admitted for abdominal pain and fever. Computed tomo...

The cuff leak test: does it "leak" any information?

Post-extubation stridor and upper-airway obstruction are multifactorial in etiology and can occur as a result of laryngotracheal edema, intubation trauma, excessive cuff pressure with mucosal ulceration, and prolonged intubation with secondary inflammation and granuloma formation.1 Cuff leak tests (CLTs) were introduced in an attempt to predict post-extubation upper-airway obstruction and reduc...
