Calpastatin is an endogenous inhibitor of calpain (calcium-dependent cysteine protease). Calpastatin activityis highly related to the rate of protein turnover and rate of meat tenderization. In order to characterize thestructure of calpastatin in Iranian Afshari breed of sheep, intron 6 and partial exon 7 of the L domain wereamplified and sequenced. A fragment of approximately...

Abstract Sugarcane bagasse is the major by‐product of sugarcane industry, and it can serve as a substrate for biotechnological processes obtaining value‐added products. This study gave multiple adding values to using in two separate bioprocesses. was used enzymatic cocktail production from Auricularia fuscosuccinea LBM 244 source proteins phenolic compounds. A . enzyme cocktail‐assisted extract...

ABSTRACT In this study, an optimized vortex-assisted method for rapid screening of oil content in Jatropha curcas L. (Jatropha) seeds is described. A 24-1IV fractional factorial design was employed to study the influence vortex stirring rate, sample:solvent ratio, extraction time, and number cycles efficiency. Gas chromatography-mass spectrometry (GC-MS) used identification fatty acids. The mos...

Ultrasound-assisted extraction of metal ions from Lithium batteries with weak organic acids is reported. Leaching reached ?98% Li and Co recovery due to improved residue layer diffusion mass transfer, illustrated by the shrinking core model.

Localization of metabolites using multiplexed mass spectrometry imaging (MSI) provides important chemical information for biological research. In contrast to matrix-assisted laser desorption/ionization (MALDI), TiO2-assisted laser desorption/ionization (LDI) for MSI improves detection of low molecular mass metabolites (<500 Da) by reducing matrix background. However, the low UV absorption of Ti...

An efficient Rh(I)-NHC-pincer catalyst for the highly regioselective Meinwald rearrangement of monoalkylated epoxides into methylketones under mild conditions is presented. The nucleophilic epoxide opening is assisted by Lewis acids.

This work describes the ultrasound-assisted synthesis of saturated aliphatic esters from synthetic aliphatic acids and either methanol or ethanol. The products were isolated in good yields after short reaction times under mild conditions.
