Assessment of Sea-Surface Wind Retrieval from C-Band Miniaturized SAR Imagery.

Synthetic aperture radar (SAR) has been widely used for observing sea-surface wind fields (SSWFs), with many scholars having evaluated the performance of SAR in SSWF retrieval. Due to the large systems and high costs of traditional SAR, a tendency towards the development of smaller and more cost-effective SAR systems has emerged. However, to date, there has been no evaluation of the SSWF retrieval performance of miniaturized SAR systems.

Critical role for αvβ6 integrin in enamel biomineralization.

Tooth enamel has the highest degree of biomineralization of all vertebrate hard tissues. During the secretory stage of enamel formation, ameloblasts deposit an extracellular matrix that is in direct contact with the ameloblast plasma membrane. Although it is known that integrins mediate cell-matrix adhesion and regulate cell signaling in most cell types, the receptors that regulate ameloblast adhesion and matrix production are not well characterized.

Integrin β6-deficient mice show enhanced keratinocyte proliferation and retarded hair follicle regression after depilation.

Integrin αvβ6 is an epithelial-specific receptor that binds and activates latent transforming growth factor-β1 (TGF-β1). TGF-β1 has been implicated as an endogenous inducer of hair follicle (HF) regression during hair cycling. We hypothesized that αvβ6 integrin-mediated TGF-β1 signaling regulates hair regeneration and HF involution.

Mice lacking beta6 integrin in skin show accelerated wound repair in dexamethasone impaired wound healing model.

Integrin alphavbeta6 is an epithelial-specific receptor that is absent from the healthy epidermis but synthesized de novo during wound repair. However, its function in wound repair is unknown. Integrin-mediated transforming growth factor-beta1 (TGF-beta1) activation is the main activation mechanism of this key cytokine in vivo.
