Effects of Extreme Dilutions of Apis mellifica Preparations on Gene Expression Profiles of Human Cells
Gene expression analysis has been employed in the past to test the effects of high dilutions on cell systems. However, most of the previous studies were restricted to the investigation of few dilutions, making it difficult to explore underlying mechanisms of action. Using whole-genome transcriptomic analysis, we investigated the effects of a wide range of Apis mellifica dilutions on gene expres...
متن کاملOccurrence of intercellular bridges between follicle epithelial cells in the ovary of Apis mellifica queens.
Hitherto unknown intercellular bridges or fusomes between the follicle epithelial cells investing the oocytes of Apis mellifica queens have been observed both with light and electron microscopy. Usually each follicle cell has 2-3 intercellular bridges. In surfacial paraffin sections, the intercellular bridges can be seen to connect a series of follicle cells which may be branching. The intercel...
متن کاملThe Effects of Apis Mellifica on Type I Hypersensitivity in Mice
The philosophy of homeopathic medications, like Apis mellifica, is that by introducing infinitesimal doses of a possible allergen, the symptoms of stress and allergic reactions can be reduced. The purpose of this study is to determine if Apis mellifica affects the allergic reaction by reducing the amount of immunoglobulin type E (IgE) antibodies in the blood. IgE is the antibody that produces a...
متن کاملStudy of the obp5 gene in Apis mellifera ligustica and Apis cerana cerana.
Apis mellifera ligustica and A. cerana cerana exhibit differences in olfactory sensitivity to odors from nectariferous plants and diseased broods. It is presumed that the differences in odorant-binding proteins (OBPs) between these 2 species contribute to their olfactory sensitivity. We compared the sequences, temporal expression pattern, and binding properties of the 2 OBP-encoding genes. We c...
متن کاملOn the Sensitivity of the Chemoreceptors on the Antenna and Fore-tarsus of the Honey-bee, Apis Mellifica L
The experiments were designed to determine the critical dilution of sucrose which would elicit a response when brought into contact with the antenna, as well as to find out the dilutions that would obtain a like response on the fore-tarsus. The criterion of response was the complete extension of the proboscis. Minnich (1921-32) has demonstrated that the tarsal joints of many insects (certain bu...
