Heinz bodies can also be found in chronic liver disease. [9] Alpha-thalassemia. Normal adult hemoglobin is composed of two alpha and two beta chains. Alpha thalassemia patients have partial or complete defects in alpha globin production, leading to a relative abundance of beta globin chains in the cell.
Fertile hybrids between bongos (Tragelaphus eurycerus) and sitatungas (Tragelaphus spekii) have occurred in captivity. [12] Hybrids between the African buffalo subspecies, the Lake Chad buffalo and African forest buffalo can occur on forest/savannah margins. Wild water buffalo and domestic water buffalo can hybridize freely. Subfamily Caprinae
These dyneins have their light chains (static portion) attached to the cell membrane, and their globular parts (dynamic portions) attached to the microtubules. The globular chains attempt to move towards the centrosome, but as they are bound to the cell membrane, this results in pulling the centrosomes towards the membrane, thus assisting ...
Haemophilia (British English), or hemophilia (American English) [6] (from Ancient Greek αἷμα (haîma) 'blood' and φιλία (philía) 'love of'), [7] is a mostly inherited genetic disorder that impairs the body's ability to make blood clots, a process needed to stop bleeding.
In animals, the process involves a sperm fusing with an ovum, which eventually leads to the development of an embryo. Depending on the animal species, the process can occur within the body of the female in internal fertilization, or outside in the case of external fertilization. The fertilized egg cell is known as the zygote. [2] [5]
The trimeric proteins intersect, composing a cruciform structure that is able to bind to other molecules of the extracellular matrix and cell membrane. [4] The three short arms have an affinity for binding to other laminin molecules, conducing sheet formation. The long arm is capable of binding to cells and helps anchor organized tissue cells ...
The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer. [2] Aquaporins have six membrane-spanning alpha helical domains with both carboxylic and amino terminals on the cytoplasmic ...
Gap Junctions have been observed in various animal organs and tissues where cells contact each other. From the 1950s to 1970s they were detected in: Human islet of Langerhans, [46] myometrium, [47] and eye lens [48] Rat pancreas, liver, adrenal cortex, epididymis, duodenum, muscle, [49] and seminiferous tubules [50] Rabbit cornea, [51] ovary ...
