Critical Examination of the Suitability of the Folin-Ciocalteu Reagent Assay for Quantitative Analysis of Polyphenols—The Case of Olive-Mill Wastewater

引用

American Journal of Analytical Chemistry 2022年第11期13卷 476-493页

作者： Mohamed Samara Ahmed Nasser uri mingelgrin The Interinstitutional Analytical Unit The Volcani Center Rishon LeZion Israel Institute of Soils Water and Environmental Sciences The Volcani Center Rishon LeZion Israel

The suitability of the Folin-Ciocalteu reagent (FCR) and of HPLC for analyzing polyphenols is evaluated. FCR assay is commonly used although its flows, such as overestimating polyphenol content due to interference by oxidizable species, were previously reported. The wide range of oxidizable species present in biological systems seriously compromises this assay’s reliability. Adding small amounts of protein to olive-mill wastewater (OMWW) significantly increased the apparent polyphenol content indicated by the FCR assay. The commonly used “reference” polyphenol as a standard for “total polyphenols” quantification is problematic since each polyphenol responds differently to the FCR. Conversely, HPLC may underestimate polyphenol content. No single HPLC protocol is likely to detect the whole myriad of polyphenols which may be present in a polyphenol-containing system. In analyzing 5 OMWW samples both by FCR assay and HPLC, the polyphenol content indicated by the FCR assay was up to six-fold higher than that determined by HPLC.

Role of capsule endoscopy in inflammatory bowel disease

引用

World Journal of Gastroenterology 2014年第5期20卷 1155-1164页

作者： uri Kopylov Ernest G Seidman Division of Gastroenterology McGill University Health Center

Videocapsule endoscopy (VCE) has revolutionized our ability to visualize the small bowel mucosa. This modality is a valuable tool for the diagnosis of obscure small bowel Crohn’s disease (CD), and can also be used for monitoring of disease activity in patients with established small-bowel CD, detection of complications such as obscure bleeding and neoplasms, evaluation of response to anti-inflammatory treatment and postoperative recurrence following small bowel resection. VCE could also be an important tool in the management of patients with unclassified inflammatory bowel disease, potentially resulting in reclassification of these patients as having CD. Reports on postoperative monitoring and evaluation of patients with ileal pouch-anal anastomosis who have developed pouchitis have recenty been published. Monitoring of colonic inflammatory activity in patients with ulcerative colitis using the recently developed colonic capsule has also been reported. Capsule endoscopy is associated with an excellent safety profile. Although retention risk is increased in patients with small bowel CD, this risk can be significanty decreased by a routine utilization of a dissolvable patency capsule preceding the ingestion of the diagnostic capsule. This paper contains an overview of the current and future clinical applications of capsule endoscopy in inflammatory bowel disease.

DMRT1 at the border between mitosis and meiosis

In males, sperm production begins at puberty and lasts throughout reproduct-ire life. This implies that a population of germ stem cells/progenitors must be main- tained, amplified and differentiate throughout life to enable the continuous supply of sperm. Spermatogenesis is indeed divided into three phases： a proliferative phase, a meiotic phase and a postmeiotic spermio- genic phase. In the proliferative phase, undifferentiated spermatogonia stem cells are divided to maintain the principle undiffer- entiated stern cell population on the one hand, and on the other hand to amplify and differentiate a fraction of the spermatogonia into primary spermatocytes.

Suggesting the use of integrated methods for vole population management in alfalfa fields

Human-made agro-ecosystems lack negative feedback controls, which may result in rodent population explosions,causing considerable economic loss and thus increasing human–wildlife conflicts. The traditional solution is theextensive use of rodenticides, which have a negative impact on the environment. In Beit-Sheaan Valley, Israel,which is located on a major route for migrating birds, poisoning of voles may result in the death of birds that preyon the dead voles (e.g. storks and herons). In the present essay we discuss some integrated methods, based on theimplementation of ecological principles in agro-ecosystems, that could be used to decrease the use of *** first method is light interference during winter (long scotophase), which can result in the death of the socialvole Microtus socialis kept in enclosures under natural conditions. Under laboratory conditions such interferencecauses a decrease in thermoregulatory ability in the cold. As light interference is a source of pollution, only activevole burrows should be illuminated. The second method involves using the mobile irrigation pipelines to flood thevole burrows and force them to escape into the open, where diurnal birds such as storks and herons will prey onthem. The third method involves the use of nesting boxes for barn owls and stands for diurnal raptors, both ofwhich prey on voles. The great advantage of using an integrated approach is that voles cannot become adapted toany one of the methods. Such integrated methods, together with appropriate treatment of alfalfa fields by farmers,can provide an efficient and sustainable pest control approach.
