Results are reported on the efficiency of polyfluorooctanol as a perfluorous auxiliary component in the aldol reaction between the enolate derived from polyfluorooctyl acetate and 2-fluorobenzaldehyde. Reduction of the corresponding polyfluoro beta-hydroxy ester with Super Hydride gave the required 1,3-diol in good yield.

Anaerobic digestion (AD) of organic wastes relies on the interaction and cooperation of various microorganisms. Phages are crucial components of the microbial community in AD systems, but their diversity and interactions with the prokaryotic populations are still inadequately comprehended. In this study, 2121 viral operational taxonomic units (vOTUs) were recovered from 12 anaerobic fatty acid-fed reactors.

Tripterygium wilfordii (TW), which has severe hepatotoxicity, is commonly used as anti-rheumatism. Using the juice of auxiliary herbs in concocting poisonous herbs is a conventional method for toxicity reduction or efficacy enhancement. Traditional Chinese Pharmacy textbooks record that Spatholobi Caulis (SC) can alleviate the side effects caused by TW and also possesses excellent hepatoprotective effect.

This work aimed to evaluate the use of Visible and Near-infrared Spectroscopy (Vis-NIRS) as a tool in the classification of bovine carcasses. A total of 133 animals (77 females, 29 males surgically castrated and 27 males immunologically castrated) were used. Vis-NIRS spectra were collected in a chilling room 24 h postmortem directly on the hanging carcasses over the longissimus thoracis between the surface of the 5th and 6th ribs.

Recurrent events data are often encountered in biomedical settings, where individuals may also experience a terminal event such as death. A useful estimand to summarize such data is the marginal mean of the cumulative number of recurrent events up to a specific time horizon, allowing also for the possible presence of a terminal event. Recently, it was found that augmented estimators can estimate this quantity efficiently, providing improved inference.

Cannabichromene (CBC), a valuable but extremely low-abundance component of cannabinoids in L., is known for its ability to promote neurogenesis. The scarcity of CBC in natural is primarily attributed to the inefficiency of the 1-deoxy-D-xylulose 5-phosphate/2-C-methyl-D-erythritol 4 phosphate (DOXP/MEP) and fatty acid metabolism pathways, along with the limited competitive advantage of cannabichromenic acid synthetase (CBCAS) compared to other cannabinoid synthases.
