Qie, Mengjie;Li, Tiwen;Liu, Charles C.;Zhao, Yan research published 《 Direct analysis in real time high-resolution mass spectrometry for authenticity assessment of lamb》, the research content is summarized as follows. In comparison to more traditional methods of determining food authenticity, such as gas chromatog. anal., the primary advantages of DART-HRMS include its high speed and throughput of anal. This study used a non-targeted metabolomics method based on real-time high-resolution mass spectrometry combined with chemometric anal. to distinguish lamb samples from four regions. Orthogonal least squares-discriminant anal. revealed a distinct difference between these four lamb regions. The potential markers were chosen based on the variables importance in projection values, variance, and fold change. A total of 79 markers were identified using the matching chem. database. These markers differed significantly between lambs in four regions according to heatmap anal. The linear discriminatory anal. model had an initial classification rate of 100.0% and a cross-validation accuracy of 82.50% on the identified markers. The research demonstrates that DART-HRMS can perform a rapid authentication evaluation of lamb samples.

Punia, Bhupinder Singh;Yadav, Praveen Kumar;Bumbrah, Gurvinder Singh;Sharma, Rakesh Mohan research published 《 Analysis of Illicit liquor by headspace gas chromatography-mass spectrometry (HS-GC-MS): a preliminary study》, the research content is summarized as follows. Illicit liquors are illegally manufactured to evade taxes and represent the majority of unrecorded liquors in developing countries. Because there are no standards, the composition of illicit liquors varies greatly from sample to sample. In the current study, we analyzed the volatile components of 27 different illicit liquors via samples collected from various locations in the northern region of India. Ethanol content varied drastically and methanol was not present in any of the samples. The components found can be categorized into different groups, namely alcs., esters, acids, nitrogen-containing components, ketones, and aldehydes. Some components-such as 1-propanol; 1-pentanol; 1-butanol; d-limonene; phenylethyl alcs.; anethole; and decanoic, octanoic, and pentanoic acids-were frequently encountered.

Prakash, Janhavi;Sallaram, Sindhoora;Martin, Asha;Veeranna, Ravindra P.;Peddha, Muthukumar Serva research published 《 Phytochemical and Functional Characterization of Different Parts of the Garcinia xanthochymus Fruit》, the research content is summarized as follows. The fruit of Garcinia xanthochymus is consumed traditionally and is known to possess health-promoting effects. However, studies involving the characterization of phytochems. of different parts of the fruit, and their biol. activity were limited and hence warranted a comprehensive study. The proximate analyses reveal that fruit peel was rich in crude fiber. The levels of essential minerals, fatty acids, amino acids, carotenoids, organic acids, and polyphenols were significantly higher in the peel, followed by the rind, seed, and pulp. The in vitro antioxidant assays revealed that the polyphenolic extract of the peel possesses a high antioxidant effect compared to the extracts from other parts of the G. xanthochymus fruit. Furthermore, the in vitro assays reveal the antidiabetic potential of the methanol extract This is the first comprehensive report involving the characterization and biol. properties of different parts of the G. xanthochymus fruit. Hence, our study implicates the potential use of this fruit for the development of functional foods for diabetes.

Ponomariov, Maria;Shabat, Doron;Green, Ori research published 《 Universal access to protease chemiluminescent probes through solid-phase synthesis》, the research content is summarized as follows. Protease chemiluminescent probes exhibit extremely high detection sensitivity for monitoring activity of various proteolytic enzymes. However, their synthesis, performed in solution, involves multiple synthetic and purification steps, thereby generating a major limitation for rapid preparation of such probes with diverse substrate scope. To overcome this limitation, we developed a general solid-phase-synthetic approach to prepare chemiluminescent protease probes by peptide elongation performed on an immobilized chemiluminescent enol-ether precursor. The enol-ether precursor is immobilized on a 2-chlorotrityl-chloride resin through an acrylic acid substituent by an acid-labile ester linkage. Next, a stepwise elongation of the peptide is performed using standard Fmoc (Fmoc = 9-fluorenylmethoxycarbonyl) solid-phase peptide synthesis. After cleavage of the peptide-enol-ether precursor from the resin, by hexafluoro-iso-propanol, a simple oxidation of the enol-ether yields the final chemiluminescent dioxetane protease probe. To validate the applicability of the methodol., two chemiluminescent probes were efficiently prepared by solid-phase synthesis with dipeptidyl substrates designed for activation by aminopeptidase and cathepsin-B proteases. A more complex example was demonstrated by the synthesis of a chemiluminescent probe for detection of PSA, which includes a peptidyl substrate of six amino acids. We anticipate that the described methodol. would be useful for rapid preparation of chemiluminescent protease probes with vast and diverse peptidyl substrates.

Polonini, Hudson;Taylor, Sarah;Zander, Clark research published 《 Compatibility of Different Formulations in TrichoConceptTM Vehicles for Hair Treatments》, the research content is summarized as follows. The wide variety of potential pathogeneses for alopecia and the wide variety of active pharmaceutical ingredients (APIs) to treat and manage those pathogeneses highlight the importance of the development of stable and effective topical treatments. Topical options for alopecia on the market remain limited and oral products may result in unwanted systemic adverse effects. This study is meant to fill the gap by determining compatibility in terms of beyond-use date (BUD) of APIs with theor. or demonstrated benefits for topical use for alopecia. The compatibility of seven formulations was tested: F1 = clobetasol 0.05% in TrichoWashTM; F2 = ketoconazole 2% in TrichoWashTM; F3 = spironolactone 1% in TrichoWashTM; F4 = latanoprost 0.1% in TrichoCreamTM; F5 = pyridoxine HCl 0.5%, vitamin A acetate 1%, and vitamin E succinate 12.1 IU in TrichoCondTM; F6 = Caffeine 2%, menthol 1%, and pyridoxine HCl 0.5% in TrichoWashTM; F7 = Latanoprost 0.1%, minoxidil 5%, and finasteride 0.25% in TrichoSolTM. All formulations presented a BUD of 6 mo, except for F4 and F7, which showed compatibility for 3 mo. This validates the compatibility of the APIs with the TrichotechTM vehicles, and that they are highly convenient for compounding pharmacies.
