As spermatids move toward the lumen of the SEMINIFEROUS TUBULES, they undergo extensive structural changes including the loss of cytoplasm, condensation of CHROMATIN into the SPERM HEAD, formation of the ACROSOME cap, the SPERM MIDPIECE and the SPERM TAIL that provides motility.Aluminum: A metallic element that has the atomic number 13, atomic symbol Al, and atomic weight 26.98.Osmosis: Tendency of fluids (e.g., water) to move from the less concentrated to the more concentrated side of a semipermeable membrane.Drug Storage: The process of keeping pharmaceutical products in an appropriate location.Accidents, AviationFibrocystic Breast Disease: A common and benign breast disease characterized by varying degree of fibrocystic changes in the breast tissue. There are three major patterns of morphological changes, including FIBROSIS, formation of CYSTS, and proliferation of glandular tissue (adenosis). The fibrocystic breast has a dense irregular, lumpy, bumpy consistency.Immunoelectrophoresis, Two-Dimensional: Immunoelectrophoresis in which a second electrophoretic transport is performed on the initially separated antigen fragments into an antibody-containing medium in a direction perpendicular to the first electrophoresis.Clopenthixol: A thioxanthene with therapeutic actions similar to the phenothiazine antipsychotics. It is an antagonist at D1 and D2 dopamine receptors.Epithelial Cells: Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

- Accordingly, the rich and lean gases have shown a better performance to enhance oil recovery in these tight formations. (springer.com)
- Gelation of hydrocolloids under shear conditions results in a weak gel which is capable of sustaining elastic mechanical deformation at small strains but which flows if subjected to higher deformations (fluid gels). (bham.ac.uk)
- In Tahe Oilfield, the elastic properties of different fluid zones indicate that bulk modulus and Young's modulus are more sensitive to fluid than shear modulus, the Lame constant, and Poisson's ratio. (geoscienceworld.org)
- Here, we demonstrate that, in experimental models with vascular polymer implants designed for the observation of neointima formation and SMC migration under defined fluid shear stress, nonuniform shear stress possibly plays a role in regulating the direction of SMC migration and alignment in the neointima of the vascular implant. (northwestern.edu)
- It was found that fluid shear stress inhibited cell growth, and the presence of nonuniform shear stress influenced the distribution of total cell density and induced the formation of cell density gradients, which in turn directed SMC migration and alignment. (northwestern.edu)
- In contrast, uniform fluid shear stress in a control model influenced neither the distribution of total cell density nor the direction of SMC migration and alignment. (northwestern.edu)
- These observations suggest that nonuniform shear stress may regulate the pattern formation of SMCs, possibly via mediating the gradient of cell density in the neointima of vascular polymer implants. (northwestern.edu)
