Royal jelly is a milky-white colored secretion produced by the hypopharyngeal and mandibular glands located in the head of young worker honeybees to feed the larvae in the colony (Münstedt and von Georgi , 2003). If a queen bee is desired, a chosen larva will be provided a large quantity of royal jelly as its only food source, which induces rapid differentiated growth and morphology. Because of...

Royal jelly has been demonstrated to have several physiological activities. However, in the literature, different reactions induced by royal jelly are reported. We describe a case of seven-year-old child that was referred to our observation for two episodes of oral allergy syndrome (OAS) that appeared ten minutes after ingestion of royal jelly. Skin prick test with standard panel of inhalant an...

We conducted a double-blind randomized controlled study of elderly individuals in a nursing home to investigate the effect of the consumption of jelly containing sea cucumber on their oral Candida load. The jelly contained a hydrolysate of the sea cucumber Stichopus japonicus, which contained triterpene glycosides called holotoxins. The holotoxins worked as a fungicide, and their minimum inhibi...

Oxidative stress is known as one of the main contributors in renal ischemia/reperfusion injury (IRI). Here we hypothesized that Micro-vesicles (MVs) derived from human Wharton Jelly mesenchymal stromal cells (hWJMSCs) could protect kidney against IRI through mitigating oxidative stress. MVs isolated from hWJMSCs conditioned medium were injected intravenously in rats immediately after unilateral...

Background. The immoderation of mitochondrial fission is one of the main contributors in ischemia reperfusion injury (IRI) and mesenchymal stromal cells (MSCs) derived extracellular vesicles have been regarded as a potential therapy method. Here, we hypothesized that extracellular vesicles (EVs) derived from human Wharton Jelly mesenchymal stromal cells (hWJMSCs) ameliorate acute renal IRI by i...

The goal of this study was to determine and compare the effects of the secretome of mesenchymal stem cells (MSCs) isolated from human bone-marrow (BMSCs) and the Wharton jelly surrounding the vein and arteries of the umbilical cord (human umbilical cord perivascular cells (HUCPVCs)) on the survival and differentiation of a human neuroblastoma cell line (SH-SY5Y). For this purpose, SH-SY5Y cells...

Coupled computational fluid dynamics and finite element analyses were used to determine the material properties of the egg and jelly layer of the sea urchin Arbacia punctulata. Prior experimental shear flow results were used to provide material parameters for these simulations. A Neo-Hookean model was used to model the hyperelastic behaviors of the jelly layer and egg. A simple compressive simu...

The purpose of this study was to investigate the effects of royal jelly against radiation-induced oral mucositis in rats. This study was comprised of 48 adult male Sprague-Dawley rats, each between eight and 12 weeks old and weighing 275±35 g. These were divided randomly into six groups; Group C (control), Group IR (irradiation), Group IR+RJ50 (irradiation plus 50 mg/kg royal jelly), Group IR+R...

The umbilical cord is not an inert structure, suspended between the fetus and placenta, but it plays an active role and it is involved in several processes afflicting the feto-placental unit. Its study has to be regarding not only its morphology and morphometry, and the impendance of blood flow by Doppler waveform analysis, but it includes also an analysis of the coiling type and the amount of ...

new approaches for treatment of infectious diseases in aquatic animals have important roles in aquaculture technology progress. in the present study, in vitro effects of different extracts of propolis, royal jelly and pollen obtained from beehives have been investigated on aquatic pathogenic bacterial isolates. the isolated bacteria identified on the basis of their biochemical properties and se...
