He found two proteins as potential markers for freshness of royal jelly protein and named them royal jelly proteins (RJP-1 and RJP-2). RJP-1 was a 57-kDa monomer which is a subunit of a larger complex (oligomer). [5] In 2011, Kamakura claimed that RJP-1 is the main protein for controlling larval development that distinguishes the queen from ...
Differences in vascular permeability between normal tissue and a tumor. Vascular permeability, often in the form of capillary permeability or microvascular permeability, characterizes the capacity of a blood vessel wall to allow for the flow of small molecules (drugs, nutrients, water, ions) or even whole cells (lymphocytes on their way to the site of inflammation) in and out of the vessel.
Developing queen larvae surrounded by royal jelly. Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens. [1] It is secreted from the glands in the hypopharynx of nurse bees, and fed to all larvae in the colony, regardless of sex or caste. [2] Queen larva in a cell on a frame with bees
First, he collected royal jelly from a group of honey bee larvae and purified the results by reverse phase, high-performance liquid chromatography. This purified royal jelly showed antimicrobial activity against different bacteria. [2] So far, four peptides have been found in this family, each one containing the carboxamide C-terminal.
The major body fluid which acts as the lifeline of the living organisms is "Blood". Blood is an extremely complex biological fluid. It consists of blood cells suspended in plasma and other different types of cells which include white blood cells, platelets etc. The blood flow in arteries and veins are closely linked to the blood vessel properties.
Arteriosclerosis, literally meaning "hardening of the arteries", is an umbrella term for a vascular disorder characterized by abnormal thickening, hardening, and loss of elasticity [3] of the walls of arteries; [4] this process gradually restricts the blood flow to one's organs and tissues and can lead to severe health risks brought on by atherosclerosis, which is a specific form of ...
The glycocalyx is located on the apical surface of vascular endothelial cells which line the lumen.When vessels are stained with cationic dyes such as Alcian blue stain, transmission electron microscopy shows a small, irregularly shaped layer extending approximately 50–100 nm into the lumen of a blood vessel.
Spiral bacteria are another major bacterial cell morphology. [2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [33] Bacteria are known to evolve specific traits to survive in their ideal environment. [34]
