The high beef price triggers adulteration of and other non-halal animal meat, such as wild boar rats. An appropriate effective analytical method is needed to differentiate halal meat. SPME/GC-MS could authenticate meat based on specific volatile compounds in each objective this study was characterize determine the marker raw beef, rat, their mixtures using SPME/GC-MS. chemometrics principal com...

aquaporins are integral membrane proteins from a larger family of major intrinsic proteins that formpores in the membrane of biological cells. aquaporins form tetramers in the cell membrane with eachmonomer acting as a water channel.in this research, the aqp4 tetramer was modeled from its pdbstructure file, then, we have performed the intraction of aquaporin4 in different temperatures (298k,300...

Thermophilic bacteria play an important role in aroma formation during pile-fermentation process of dark tea. With the aim to reveal impact thermophilic on volatile compounds tea, Bacillus licheniformis (thermophilic bacteria) were inoculated into sun-dried green tea for spontaneous fermentation. In this study, headspace solid phase microextraction combined gas chromatography mass spectrometry ...


 Purpose: To screen quality markers of Jie-Geng decoction (JGD) through multiple analytical methods and integration network pharmacology HPLC-ELSD fingerprint.
 Methods: Network was used to the potential bioactive components JGD. Simultaneously, fingerprint combined with carried out for determination chemical compounds in Subsequently, identification variations JGD were established r...

Abundant peptides and proteins containing arginine (Arg) and lysine (Lys) amino acids can apparently permeate cell membranes with ease. However, the mechanisms by which these peptides and proteins succeed in traversing the free energy barrier imposed by cell membranes remain largely unestablished. Precise thermodynamic studies (both theoretical and experimental) on the interactions of Arg and L...

Worldwide growth and performance-enhancing substances are used in cattle husbandry to increase productivity. In certain countries however e.g., in the EU, these practices are forbidden to prevent the consumers from potential health risks of substance residues in food. To maximize economic profit, 'black sheep' among farmers might circumvent the detection methods used in routine controls, which ...

The purpose of this study was to determine whether metabolic profiling of core needle biopsy (CNB) samples using high-resolution magic angle spinning (HR-MAS) magnetic resonance spectroscopy (MRS) could be used for predicting pathologic response to neoadjuvant chemotherapy (NAC) in patients with locally advanced breast cancer. After institutional review board approval and informed consent were ...
