sPIF promotes myoblast differentiation and utrophin expression while inhibiting fibrosis in Duchenne muscular dystrophy via the H19/miR-675/let-7 and miR-21 pathways [PDF]

, 2019
Duchenne muscular dystrophy (DMD) is a progressive, lethal, X-linked disease of skeletal and cardiac muscles caused by mutations in the dystrophin gene. Loss of dystrophin leads to muscle fiber damage and impairment of satellite cell asymmetric division,

Influence of global forced-air warming on the bulge formation in shallow sloped SPIF parts

, 2022
S.149-154Shallow sloped single point incrementally formed (SPIF) parts typically show undesirable geometric deviations from the designed shape due to accumulated unwanted bulging. In this study, the effect of global warm forming using a forced- air flow,

Parametric effects on formability of AA2024-O aluminum alloy sheets in single point incremental forming

Journal of Materials Research and Technology, 2019
Single point incremental forming (SPIF) is a truly die-less forming process which is quite suitable for the batch type and prototype production due to economical tooling cost, shorter lead time and ability to form nonsymmetrical geometries without using ...
