The nuclear rDNA region of <i>Gyrodactylus arcuatus</i> and <i>G. branchicus</i> (Monogenea: Gyrodactylidae) OMA
Zietara, M.S.; Arndt, A.; Geets, A.; Hellemans, B.; Volckaert, F.A.M.J..
The primary structure of the ribosomal DNA internal transcribed spacers (ITS-1 and ITS-2) and 5.8S rRNA gene were used to characterize and identify 2 monogenean species of <i>Gyrodactylus</i> living externally on the threespine stickleback (<i>Gasterosteus aculeatus</i>). The ITS region was amplified by PCR from freshwater, brackish, and marine isolates of <i>Gyrodactylus arcuatus</i> and <i>G. branchicus</i>, and the ends of the coding regions were identified by comparative alignment. No intraspecific and very low interspecific variation were observed in the 5.8S rRNA gene; high inter- and low intraspecific variation were revealed in the ITS-1 and ITS-2 regions. The morphological species identification was...

This study investigated the influences of paddy aging at 60 C and 70% relative humidity for 5 days on pasting properties of rice flours and molecular structures of major constituents in rice grain. The rice cultivars investigated included waxy rice Sanpah-Tawng 1 (SPT1), which contained 1.3% amylose and 8.3% protein. Non-waxy rice paddies; namely Pathum Thani 1 (PTT1), which had 14.1% amylose and 6.7% protein, as well as and Leuang Pratew 123 (LPT123), which contained 28.6% amylose and 9.6% protein, were also investigated. Paddy aging significantly changed the RVA pasting characteristics of rice flour pastes from all cultivars investigated (p<0.05). All aged rice flour pastes had higher final viscosity than that of new rice flour paste. Fourier...

Effects of surface proteins and lipids on molecular structure, thermal properties, and enzymatic hydrolysis of rice starch Ciênc. Tecnol. Aliment.
HU,Pan; FAN,Xiaoxu; LIN,Lingshang; WANG,Juan; ZHANG,Long; WEI,Cunxu.
Abstract Rice starches with different amylose contents were treated with sodium dodecyl sulfate (SDS) to deplete surface proteins and lipids, and the changes in molecular structure, thermal properties, and enzymatic hydrolysis were evaluated. SDS treatment did not significantly change the molecular weight distribution, crystalline structure, short-range ordered degree, and gelatinization properties of starch, but significantly altered the pasting properties and increased the swelling power of starch. The removal of surface proteins and lipids increased the enzymatic hydrolysis and in vitro digestion of starch. The influences of removing surface proteins and lipids from starch on swelling power, pasting properties, and enzymatic hydrolysis were different...
