After that, the supernatant was eliminated, titrated, & kept at −80 °C until needed. Uninfected monolayer in medium served as the negative control for the controls. Vero cells lyse as they pass further to reach high virus titers. 2.3.2. Examination of cytopathic effect (CPE) According ...
It is for proteins of this class that progress is slowest and, from the standpoints of basic and applied biomedical science, most needed. It is noted with regret that the scope of this review does not encompass the many published NMR studies of single-span or peripheral membrane proteins (...
Therefore, based on the Bact-HOB sample studied in the present study, it is not possible to draw general conclusions on the protein digestibility of bacterial biomass samples, and further experiments are needed. The impact of heat treatments on the protein digestibility of samples Myco-Rhizopus ...
However, since TMS derivatives can lose easily trimethylsilanol molecules under the effect of moisture, a short delay between derivatization and injection is needed. Despite this drawback, silylation is a very popular derivatization method and is often employed during sterol quantification using GC-MS ...
Figure 1.(a) The total peak area and (b) the total peak number extracted using different vial sizes. Thep-value was calculated based on the one-way ANOVA test followed by Turkey’s test. *p-value < 0.05; ***p-value < 0.001; ****p-value < 0.0001. The “ns” stands for “not st...
The aim of this study is the analysis of the in vitro digestion of corn oil, and of the effect of its enrichment with three levels of gamma- and alpha-tocopherol, by using, for the first time, 1H nuclear magnetic resonance (1H NMR) and a solid phase microextraction followed by gas chro...
(3.0, 7.0, and 10.0). For these experiments, the sample pH was adjusted by adding 0.1 M hydrochloric acid or 0.1 M sodium hydroxide (n = 3 for each tested sample pH), and the samples were subjected to UA-DLLME-LC–MS/MS analysis using the procedure described inSection 2.5, followed ...
However, as MC congeners are known to differ in their toxicity, methods are needed that simultaneously quantify the congeners present, thus allowing for summary hazard and risk assessment. Moreover, detection of MCs should be expanded to complex matrices, e.g., blood and tissue samples, to ...
Of course, further studies are needed to test the idea, but the retromer-mediated retrograde transport, the ethanolamine metabolism, and consequently the endocannabinoid signaling [59], and phospholipid metabolism [82] can be important targets for future therapies aiming to alleviate insulin resistance....
