The left-right asymmetry of snails, including the direction shell coiling, is determined by delayed effect a maternal gene on chiral twist that takes place during early embryonic cell divisions. Yet, despite being well-established classical problem, identity and means which established in snails remain unknown. We here demonstrate power new genomic approaches for identification chirality gene, "D". First, heterozygous (Dd) pond Lymnaea stagnalis were self-fertilised or backcrossed, genotype...
This paper proposes a vibration-based structural damage detection approach considering the effects of uncertainties, including environmental variations and random errors that possibly stem from measurement automatic modal identification. The existing methods only employ classical Principle Component Analysis (PCA) have been demonstrated effective to remove while extremely sensitive errors. Therefore, robust PCA is firstly introduced errors, especially outliers, significantly corrupt low-rank...
Sangju Ganmao tablet (SGT), a well-known Chinese patent medicine used to treat cold symptoms, is made from eight herbal medicines. In this study, an off-line hydrophilic interaction × reversed-phase two-dimensional liquid chromatography (HILIC RP 2D-LC) method was developed comprehensively separate the chemical constituents of SGT. Through optimization experimental conditions, total 465 peaks were finally detected in SGT, and structures 54 selected compounds fully identified or tentatively...
A novel approach for determination of 2-mercaptobenzimidazole (MBI) and other thyreostatic residues in animal tissues by gas chromatography/mass spectrometry (GC/MS) selected ion monitoring mode was developed. The analytes (including hypothyroid, pork muscle beef samples) were extracted acetonitrile, then purified a matrix solid-phase dispersion (MSPD) procedure after the extraction had been dissolved water. derivatized pentafluorobenzyl bromide (PFBBr) under strong basic conditions...
A novel approach for differentiation and dating of red ink entries seals on documents was developed based ion-pairing HPLC (IP-HPLC) GC/MS. Sixty-nine pastes were collected the chromatographic conditions separation dye components by IP-HPLC volatile additives GC/MS in optimized. According to additives, classified with a multi-wavelength UV detector. The inks identified classification also investigated these additives. results showed that most can be differentiated combining detector methods....
This study examined the distribution of selenium in proteins from selenium-enriched Cordyceps militaris extract using reversed-phase high performance liquid chromatography (RP-HPLC) and size-exclusion (SEC) coupled to on-line ICP-MS specific for detection. An analytical method was developed detecting presence selenocysteine, selenomethionine selenopeptides. The results showed that soluble major form C. extract. About 84.4% present as low-molecular-weight molecules (MW < 4 kDa), whereas 7.13%...
Overalkylation often appears during the proteolytic digestion process when using iodoacetamide (IAM) to protect produced side chain thiol of Cys from disulfide bonds.
A simple and sensitive liquid chromatography method with diode array detector was established for simultaneous determination of 11 components (geniposidic acid, chlorogenic caffeic geniposide, luteoloside, isochlorogenic acid C, baicalin, luteolin, wogonoside, baicalein wogonin) in various commercial Yinzhihuang preparations their herbs by optimizing the extraction, separation analytical conditions. Eleven were identified on basis retention times mass spectra. Chromatographic performed a C18...
The family Orobanchaceae including autotrophic, hemiparasitic, and holoparasitic species, is becoming a key taxa to study the evolution of chloroplast genomes in different lifestyles. But early evolutionary trajectory transit from autotrophism hemiparasitism still maintains unclear for inadequate sampling. In this study, we compared 50 complete Orobanchaceae, containing four newly sequenced plastomes hemiparasitic Pedicularis, elucidate sequence variation patterns plastomes. Contrasted...
We investigated the vulnerable fish species Schizothorax argentatus Kessler, 1874, using low-coverage whole genome sequencing data. The assembled 16,587 bp mitochondrial has a nucleotide composition of A = 29.8%, T 25.3%, G 17.9%, and C 27.0%, containing 13 protein-coding genes, two ribosomal RNA 22 transfer genes with gene arrangement identical to other cofamilial species. Phylogenetic analyses 71 schizothoracine fishes suggest close relationship between S. eurystomus, sharing common...
Abstract A novel method for simultaneous determination of 8 sulfonamide residues (sulfathiazole, sulfapyridine, sulfadiazine, sulfamerazine, sulfamonome-thoxine, sulfachloropyridazine, sulfamethoxazole, and sulfadimethoxine) in honey samples by high-performance liquid chromatography (HPLC) has been developed on the basis precolumn derivatization with 9-fluorenylmethyl-chloroformate (FMOC-Cl). Sulfonamide were extracted purified matrix solid-phase dispersion C18 as solid support. The...
A novel approach for simultaneous determination of 12 sulphonamides (sulphadiazine, sulphamethazine, sulphathiazole, sulphadimethoxine, sulphamerazine, sulphapyridine, sulphamethoxazole, suphamethizole, sulphaquinoxaline, sulphameter, sulphamonomethoxine, and sulphachloropyridazine) in animal tissues (swine muscle liver, chicken muscle, beef muscle) by HPLC with UV detection has been developed. pre-column derivatization the sulphonamide compounds 9-fluorenylmethyl chloroformate (FMOC-Cl)...
Abstract Length variation and heteroplasmy were observed in PCR products of the first half mtDNA control region both Hong Kong grouper ( Epinephelus akaara ) yellow awoara ). DNA sequencing unveiled phenomena caused by presence species‐specific long variable number tandem repeats (VNTRs). This is report on VNTRs their groupers. Moreover, these are also longest such structure found teleost fish. Thereafter, we designed two reverse primers according to 3′ end sequences successfully established...
