OBJECTIVES This study aims to investigate the effects of radiation on serum trace elements and the changes in these elements as induced by royal jelly in rats undergoing head and neck irradiation. MATERIALS AND METHODS Thirty-two Sprague-Dawley male rats at the age of eight weeks with a mean weight of 275±35 g were included in the study. Subjects were divided into four groups with eight rats ...
Objective: To investigate the anti-bacterial properties of royal jelly against six different bacteria (Escherichia coli, Staphylococcus aureus, Streptomyces griseus, and three unclassified strains of
The major environmental determinants of honeybee caste development come from larval nutrients: royal jelly stimulates the differentiation of larvae into queens, whereas beebread leads to worker bee fate. However, these determinants are not fully characterized. Here we report that plant RNAs, particularly miRNAs, which are more enriched in beebread than in royal jelly, delay development and decr...
Involvement of children in gardening has the potential to increase liking of fruit and vegetables (FV) and consequently, intake, but research results are mixed. School gardening led by external specialists such as the Royal Horticultural Society (RHS) could have more impact than teacher-led gardening on children's knowledge of, and attitudes towards, FV. Data from a cluster randomised controlle...
An aqueous extract of royal jelly from Apis mellifera produced hypoglycemia when injected into larvae of Manduca sexta. Application of specific radioimmunoassay to the partially-purified extract showed that royal jelly contains several insulin-like peptides, the major immunoreactive component of which has an apparent mol. wt similar to that of bovine insulin. These results suggest the existence...
the effect of honey, royal jelly and bee pollenon performance, immune system and blood factors of japanese quail, using 160 quail chicks in a completely randomized design by four treatments ]control (without additives), pollen powder 1 g/kg, royal jelly 125 ppm/l, honey 22 g/l) and four replicates of 10 chicks in each replication for 42 days. the experimental groups had no significant effect on...
Carbendazim is usually used to control the Sclerotinia sclerotiorum of rapes during the flowering period. This paper presents a study on transfer assessment of carbendazim residues from rape flowers to apicultural products. In the field trials, the rapes were sprayed with carbendazim on standard dosage. Bees produced apicultural products (bee pollen, honey, and royal jelly) from sprayed rapes. ...
Introduction: Studies have proposed that royal jelly(RJ) has various biological activities in different cells and tissues. Since it has been demonstrated that RJ contains compounds having desirable effects on central neurons system and neural functions, the present study aimed to investigate the effect of royal jelly on learning and memory in rats. Methods: Male wistar rats were divided into t...
Background & aim: Given that Royal Jelly contains compounds that have beneficial effects on the central nervous system and neural functions, the aim of this study was to investigate the effect of eight weeks of Royal Jelly consumption on some of apoptotic characteristics in trimethyltin-induced Alzheimerchr('39')s rats Methods: The present study was performed experimentally with 32 male rats; T...
Royal jelly is a viscous jelly substance. It is partially soluble in water with a density of 1.1 g/mL. Its colour is whitish to yellow, the yellow colour increasing upon storage. Its odour is sour and pungent, the taste being sour and sweet. The sensory characteristics are important quality criteria. Old royal jelly, which has not been properly stored tends to be darker and a rancid taste can d...
