This study evaluated the impact of processing, packages (amber and transparent glass jars), storage time on stability bioactive compounds (total phenolic vitamin C), antioxidant activity mangaba jelly. Jelly significantly (p < 0.05) decreased activity. The time, influenced all variables studied in this work, although they were not affected by packages. A significant decrease was observed during...

background royal jelly (rj), a food item secreted by worker honeybees, is a mixture that contains protein, glucose, lipid, vitamins, and minerals; it is widely used as a commercial medical product. previous studies have shown that rj has a number of physiological effects, such as anti-inflammatory, antitumor, antiallergic and antioxidant activities. objectives in the present study, the anti-inf...

conclusions it seems that rj does not appear to have significant immediate effects on glycemic factors in patients with type 2 diabetes. however, further studies with larger sample sizes and different doses of rj are needed to achieve more precise results. background type 2 diabetes is the fourth major public health problem worldwide. royal jelly (rj) insulin-like activity and blood glucose mod...

This paper presents a study on the transfer and metabolism of triadimefon residues from rape flowers to apicultural products. In the field trials, honeybee colonies were placed in four rape greenhouses treated with triadimefon on standard dosage. Apicultural products (pollen, honey, and royal jelly) were collected on a regular basis. Sample preparation and extraction procedure were established....

Objective: Umbilical cord Wharton’s jelly as source of mesenchymal stem cells (MSCs) can be easily obtained. In this study, MSCs were isolated from bone marrow and Wharton’s jelly and induced to differentiate into endothelial-like cells. Materials and Methods: MSCs were isolated and induced to differentiate into endothelial-like cells using vascular endothelial growth factor (VEGF). The endothe...

The inner egg capsule of embryos of the yellow-spotted salamander (Ambystoma maculatum) are routinely colonized by green algae, such as Oophila amblystomatis, that supply O(2) in the presence of light and may consume nitrogenous wastes, forming what has been proposed to be a mutualistic relationship. Given that A. maculatum have been reported to breed in acidic (pH <5.0) and neutral lakes, we h...

Spawning marine invertebrates are excellent models for studying fertilization and reproductive isolating mechanisms. To identify variation in the major steps in sea urchin gamete recognition, we studied sperm activation in three closely related sympatric Strongylocentrotus species. Sperm undergo acrosomal exocytosis upon contact with sulfated polysaccharides in the egg-jelly coat. This acrosome...

A food developed at the Hiroshima Prefectural Food Technology Research Center, Hiroshima, Japan, has proved to be a boon in videofluorography. The food features decreased hardness with retained their shape due to being impregnated with macerating enzymes under reduced pressure after vegetables are defrosted. Samples were removed immediately from the enzyme solution after freeze infusion. All fo...

When, at about the 40th hour of incubation, the heart of the embryonic chick begins to pump blood it is essentially a simple tubular structure, looped to the right. I t s wall consists of a tube of endothelium within a sleeve of epimyocardium. In living as well as in fixed preparations there is a space between these tmo layers. I n the living condition this space appears optically homogeneous. ...
