Plasma membrane structure of bat spermatozoa was examined utilizing electron microscopy of thin sections and freeze-fracture replicas. Notable membrane features observed in replicas from cauda epididymal spermatozoa included specialized particle aggregates at the junction between the acrosomal and postacrosomal...

1. A sealing structure of a plasma processing apparatus, which seals an opening of a plasma generation chamber in which a plasma process is performed, the sealing structure comprising: a ring-shaped first sealing member being exposed to a plasma atmosphere in the plasma generation chamber; a rin...
Membrane structure 1. Introduction The cell envelope provides protection from the environment and gives structural integrity to the cell in all organisms. Homeostasis of the plasma membrane is vital for functioning of the cell and the bacterial phage shock protein (Psp) response protects the bacterial...
Classically, G-protein-coupled receptors (GPCRs) are thought to activate G protein from the plasma membrane and are subsequently desensitized by β-arrestin (β-arr). However, some GPCRs continue to signal through G protein from internalized compartments, mediated by a GPCR–G protein–β-arr ...

(A) Patients carrying ApoA-I amyloidogenic variants possess reduced levels of plasma ApoA-I. Proteins from serum sample from patients and control subjects were separated by denaturant PAGE and analyzed by Western blot by using anti-human ApoA-I antibody (upper panel), and ApoA-I levels were ...
P-type ATPases use the energy from ATP hydrolysis to pump ions across the cell membrane against a concentration gradient. They form a large family of ubiquitous membrane proteins, and carry out many essential processes, such as generating the membrane potential or removing toxic ions from cells....
It is now well established that the properties of plasma membranes of transformed and malignant cells differ from those of normal cells (Spector and Burns, 1987). However, most of the investigations refer to the properties of the proteins in the membrane and their interaction with the lipid bila...
Get PDF (1585K) Abstract The fine structure of the intersegmental glands of the sixth abdominal sternum in 1-week old females of Nomia melanderi is presented. The plasma membrane of the secretory cell is unfolded in many places and is covered by a basement membrane. The microvillous surface...
