A balance between the anti-apoptotic activity of Slug and the apoptotic activity of msx1 is required for the proper development of the neural crest
(Academic Press Inc Elsevier Science, 2004-11)
We have studied the pattern of programmed cell death in the neural crest and analyzed how it is controlled by the activity of the transcription factors Slug and msx1. Our results indicate that apoptosis is more prevalent ...
Epigenetic regulation in neural crest development
(Academic Press Inc Elsevier Science, 2014-11)
The neural crest is a migratory and multipotent cell population that plays a crucial role in many aspects of embryonic development. In all vertebrate embryos, these cells emerge from the dorsal neural tube then migrate ...
MicroRNAs and the neural crest: From induction to differentiation
(Elsevier Science, 2018-12)
MicroRNAs are small noncoding RNAs that can control gene expression by base pairing to partially complementary mRNAs. Regulation by microRNAs plays essential roles in diverse biological processes such as neural crest ...
Cascade Sliding Control for Trajectory Tracking of a Nonholonomic Mobile Robot with Adaptive Neural Compensator
(Hindawi Publishing Corporation, 2017-07)
A design of sliding mode controllers (SMC) with adaptive capacity is presented. This control technique is formed by two cascaded SMC controllers, one of them having an adaptive neural compensator (ANC); both are put on a ...
Identification and adaptive PID Control of a hexacopter UAV based on neural networks
(John Wiley & Sons Ltd, 2019-01)
In this paper, a novel adaptive PID controller for trajectory-tracking tasks is proposed. It is implemented in discrete time over a hexacopter, and it takes into consideration the unmanned aerial vehicles (UAVs) nonlinear ...
A new role for the Endothelin-1/Endothelin-A receptor signaling during early neural crest specification
(Academic Press Inc Elsevier Science, 2008-11)
The neural crest is induced at the border of the neural plate in a multistep process by signals emanated from the epidermis, neural plate and mesoderm. In this work we show for the first time the existence of a neural crest ...

Self-tuning of a Neuro-Adaptive PID Controller for a SCARA Robot Based on Neural Network
(Institute of Electrical and Electronics Engineers, 2018-05)
In this paper a MIMO (Multiple-Input-Multiple-Output) adaptive neural PID (AN-PID) controller that can be applied to a nonlinear dynamics is proposed, and its use is shown in the control of a SCARA robot for two degrees ...

Aerial Load Transportation with Multiple Quadrotors Based on a Kinematic Controller and a Neural SMC Dynamic Compensation
(Springer, 2020-04)
A novel formation control to transport a cable-suspended payload with two quadrotors is presented. The control structure is based on a layered scheme combining a kinematic null-space based controller and a neural sliding ...
