Examples of non-three-domain toxins that nevertheless have a Cry name include Cry34/35Ab1 and related beta-sandwich binary (Bin-like) toxins, Cry6Aa, and many beta-sandwich parasporins. [ 18 ] Specific delta-endotoxins that have been inserted with genetic engineering include Cry3Bb1 found in MON 863 and Cry1Ab found in MON 810 , both of which ...
Human tears. Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals. [1] Tears are made up of water, electrolytes, proteins, lipids, and mucins that form layers on the surface of eyes.

In 1995, potato plants producing CRY 3A Bt toxin were approved safe by the Environmental Protection Agency, making it the first human-modified pesticide-producing crop to be approved in the US, [57] [58] though many plants produce pesticides naturally, including tobacco, coffee plants, cocoa, cotton and black walnut. This was the 'New Leaf ...
Here's what might be causing your tears—and what to do about it. ... "And sometimes, the release happens at a time that we feel is inconvenient or embarrassing. But just because it feels that ...
Rhinorrhea is also associated with shedding tears (lacrimation), whether from emotional events or from eye irritation. When excess tears are produced, the liquid drains through the inner corner of the eyelids, through the nasolacrimal duct, and into the nasal cavities. As more tears are shed, more liquid flows into the nasal cavities, both ...
Most Clostridium species that do have toxins typically have binary toxins with the first unit involved in getting the toxin into the cell and the second unit cause cellular stress or deformation. [6] Clostridial toxins are widespread and aid in the production of many diseases in humans and other organisms.
