Piezoelectric electronics possess great potential in flexible sensing and energy harvesting applications. However, they suffer from low electromechanical performance in all-organic piezoelectric systems due to the disordered and weakly-polarized interfaces. Here, we demonstrated an all-polymer piezo-ionic-electric electronics with PVDF/Nafion/PVDF (polyvinylidene difluoride) sandwich structure and regularized ion-electron interfaces.

A liquid crystal elastomer (LCE) actuator capable of colorimetric humidity sensing is realized. The designed LCE features acid protonated amino azobenzene side groups in its structure, which endow the actuator with the hygroscopicity and act as the humidity reporter via color changes. Given that the protonated and deprotonated chromophore absorb visible light at different wavelengths, when the protonated LCE is under higher humidity, it absorbs more water that deprotonates azobenzene and leads to a change in color.

Lateralization of motor behavior, a common phenomenon in humans and several species, is modulated by the basal ganglia, a site pointed out for the interhemispheric differences related to lateralization. Our study aims to shed light on the potential role of the striatonigral D1 receptor in functional asymmetry in normal conditions through neurochemical and behavioral means. We found that D1 receptor activation and D1/D3 receptor coactivation in striatonigral neurons leads to more cAMP production by adenylyl cyclase in the striatum and GABA release in their terminals in the right hemisphere compared to the left.

Objectives: Cyclic vomiting syndrome (CVS) remains a diagnostic challenge due to its nonspecific presentation despite consensus-based diagnostic criteria. There is a need for improved, evidence-based diagnostic criteria. We hypothesized that symptoms differ quantitatively between children with CVS versus other vomiting conditions and that current diagnostic criteria are not sufficiently sensitive for diagnosing CVS.

Background: The most susceptible group of people to spread methicillin-resistant (MRSA) among domestic cats is their owners' relatives.
Aim: Considering the aforementioned, research at the Surabaya City Animal Hospital is necessary to determine whether the A gene may be detected in cat nasal swabs.
Methods: Samples were taken using a sterile cotton swab, and the transport medium was buffered peptone water.
