Targeted Local Delivery via Fiber‐Embedded Flexible Microchannels Integrated with Film‐Based Implantable Probes

Advanced Materials Technologies, EarlyView.
In this study, a fiber‐embedded drug delivery channel for implantable microprobes, demonstrating the first functional drug delivery system using flexible LCP‐based probes, is developed. The design incorporates fibers for site‐selective drug delivery and electrical functions. The utilization of monolithic thermal bonding simplifies fabrication.

Photoactive Monolayer MoS2 for Spiking Neural Networks Enabled Machine Vision Applications

Advanced Materials Technologies, EarlyView.
Molybdenum disulfide (MoS2) optoelectronic devices are implemented as Leaky Integrate‐and‐Fire (LIF) neurons in spiking neural networks (SNNs), where light‐induced photocurrent dynamics represent potentiation (τd) and depression (τd), emulating neuronal membrane potential.

Improper Supplementation Habits of Folic Acid Intake by Hungarian Pregnant Women: Improper Recommendations [PDF]

, 2008
Background: Neural tube defects (NTDs) are some of the most common congenital anomalies. Proper folic acid supplementation is a dominant risk factor, which has been shown to decrease the incidence of NTDs.

Dishevelled genes mediate a conserved mammalian PCP pathway to regulate convergent extension during neurulation [PDF]

, 2006
The planar cell polarity (PCP) pathway is conserved throughout evolution, but it mediates distinct developmental processes. In Drosophila, members of the PCP pathway localize in a polarized fashion to specify the cellular polarity within the plane of the

A zinc transporter gene required for development of the nervous system. [PDF]

, 2013
The essentiality of zinc for normal brain development is well established. It has been suggested that primary and secondary zinc deficiencies can contribute to the occurrence of numerous human birth defects, including many involving the central nervous ...

Emerging Therapeutic Strategies for Hearing Loss

Advanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or
