Enamel is the hardest and most resilient tissue in the human body. Enamel includes morphologically aligned, parallel,∼50 nm wide, microns-long nanocrystals, bundled either into 5-μm-wide rods or their space-filling interrod. The orientation of enamel crystals, however, is poorly understood....
3, the structure of the cell membrane is characterized by a certain fluidity, and the functional characteristics are selective permeability. Such as: any part of the amoeba can reach out, the body of certain white blood cells can eat bacteria, these physiological completion depends on the ...
In some cases, a combined effect occurs whereby the antibody activates the targeted molecule but induces surface molecule internalization, effectively clearing the molecule from the cell surface and inhibiting its subsequent function.151 This transient activation effect can lead to a burst of target ...
If two cells are adjacent, but separated, they may be junctured bydesmosomes. Desmosomes are dense accumulations of protein at the cytoplasmic surface of the plasma membranes of both separate cells. They are infiltrated with protein fibers that extended into either cell. The purpose and function...
As proteins move through the Golgi body they're customized into forms that the cell can use. 随着蛋白质穿过高尔基体,它们被定制成细胞可以使用的形式。 The Golgi body does this by folding the proteins into usable shapes,or adding other materials on to them such as...
BACKGROUND: Human galectin-3 (Mac-2 antigen) is a cell-type-specific multifunctional effector owing to selective binding of distinct cell-surface glycoconj... K Kitamori,M Kobayashi - 《Lkartidningen》 被引量: 34发表: 1995年 Memmler's the structure and function of the human body Unit I: ...
Development of vehicle body components relevant for side impact and assessment of the achieved occupant safety Therefore, the target of crashworthiness studies is an optimised vehicle structure with controlled deformation zones in order to maintain sufficient space inside the passenger cell. In particular,...
The structures of RSC complex (PDB:6TDA)15,16,55, (PDB:6KW4)16, and structure of BAF complex (PDB:6LTJ)14were used as initial structural templates, which were fitted into the cryo-EM maps by rigid-body fitting using UCSF Chimera followed by iterative rounds of manual adjustment and rebu...
Epidermal growth factor (EGF) regulates cell proliferation and differentiation by binding to the EGF receptor (EGFR) extracellular region, comprising domains I–IV, with the resultant dimerization of the receptor tyrosine kinase. In this study, the crystal structure of a 2:2 complex of human EGF ...
