On the Indifferentiability of Fugue and Luffa

2011
Indifferentiability is currently considered to be an important security notion for a cryptographic hash function to instantiate Random Oracles in different security proofs. In this paper, we prove indifferentiability of Fugue and Luffa, two SHA3 second round candidates. We also analyze the indifferentiability of a modified Luffa mode replacing multiple

Chemical examination of Luffa echinata

Phytochemistry, 1971
Abstract In the fruit of Luffa echinata, the rare flavonoid, chrysoeriol occurs along with its 7-glucoside and 7-apioglucoside. Two other flavones, apigenin and luteolin are also found in minor amounts as glycosides. As already reported, elaterin and isocucurbitacin-B occur along with the bitter elaterin-2-glucoside and β-sitosterol glucoside. Apiose

Fabrication and analysis of luffa natural fiber based acoustic shielding material for noise reduction

Journal of Natural Fibers, 2022
High persistence of different types of noises in the environment is a challenging problem nowadays. Many natural fiber composite works have been introduced in this line to execute the efficiency with their own compositional properties to some extent ...

Selected Pharmacological Studies of Luffa operculata

Journal of Pharmaceutical Sciences, 1974
An aqueous extract of Luffa operculata Cong. Cucurbitaceae (Cabacinha) was tested in mice for the following pharmacological effects: toxicity, analgesia (“grid shock” method), alteration of neuromuscular coordination (rotarod), and modification of barbiturate metabolism (hexobarbital sleeping time).

Phylogeny and Distribution of Luffa (Cucurbitaceae)

Biotropica, 1988
The genus Luffa comprises five species of tropical vines, four native to the Old World and one, L. operculata, to the New World. Two species, L. aegyptiaca and L. acutangula, include domesticated plants that are now widespread in the tropics. Interspecific hybrids are sterile or nearly so. Intraspecific hybrids within L. acutanglda and L.

Hepatoprotective activity of Luffa echinata fruits

Journal of Ethnopharmacology, 2001
The different extracts of the fruits of Luffa echinata Roxb. (Cucurbitaceae) were tested for their hepatoprotective activity against CCl(4) induced hepatotoxicity in albino rats. The degree of protection was measured by using biochemical parameters like serum glutamic oxalacetic transaminase (SGOT), serum glutamic pyruvate transaminase (SGPT), alkaline
