Summary: The study found that children as young as 3 years old are capable of performing basic chewing functions similar to adults, but there are differences in the anticipation or adaptation of jaw muscle activity and jaw movements to food hardness. By the late permanent dentition stage (15-17 years), children are able to exhibit adult-like chewing behavior.

Summary: This study examined the coordination of respiration and swallowing in healthy humans through various experiments. It was found that the major coordination pattern of respiration and swallowing was expiration-swallow-expiration (EE type) during voluntary swallowing and chewing. Understanding the mechanisms underlying respiration and swallowing is crucial for evaluating how coordination affects physiological swallowing in dysphagic patients.

Summary: This study suggests that the prevalence of poor dental occlusion in modern industrialized societies is a result of consuming more heavily processed foods, which led to a reduction in jaw size during the Industrial Revolution. Analysis of dental macrowear patterns revealed changes in masticatory behavior during the early stages of transitioning to processed foods. The shift towards softer diets has transformed occlusal power stroke kinematics, resulting in a dental revolution with diminished occlusal contacts.

Summary: The gut environment, including the microbiota and its metabolites, is crucial for maintaining health. This study suggests that habitual mastication and feeding powdered diets can impact the gut microbiota and environment. The findings reveal that powdered diet feeding leads to changes in the gut microbiota, constipation-like symptoms, and suppressed colonic motility, which can be improved by masticatory activity.

Summary: This study used atmospheric pressure chemical ionization mass spectrometry to monitor in real-time the key odorants released from grilled eel during mastication. The results showed that the release and perception of odorants during mastication can be divided into three distinct phases, and recommended extending the chewing period and increasing the chewing frequency to optimize the consumer experience.

Summary: The study found that different diets have varying impacts on dental microwear texture in animals, with posterior tooth positions experiencing more wear from plant diets and a more uniform wear distribution along the tooth row from pelleted diets. This is due to the continuous intake and comminution of plant material during feeding, resulting in opposing wear gradients for plant versus pelleted diets.

Summary: The tongue undergoes complex deformations during chewing and drinking, with different regions showing biomechanical and functional variations. Tongue deformations are larger during chewing compared to drinking, and the timing of regional length and width deformations differ between the two behaviors. This study provides critical insights into regional contributions to tongue deformations and sets the basis for future research on multidimensional shape changes in soft tissues.

Summary: The development of cost-effective, high-performance catalysts at the atomic level is crucial for large-scale applications of renewable clean energy conversion. Single-atomic site catalysts (SACs) have great potential as next-generation materials, with the introduction and coupling of synergistic components to improve activity. Various atomic-coupling structures, including SAC-NPs, SACCs, DACs, and SAAs, offer unique synergistic effects that need further exploration and comparison.

Summary: Chewing food prepares it for safe swallowing by reducing particle size, exposing new surface, and blending it with saliva to benefit both digestion and the sensory experience of consumers. Feed technologists play a role in enhancing the outcomes of a multitude of rate processes, including particle size reduction through subsequent selection and breakage in each chewing cycle.

Summary: Potential-dependent selectivity changes are widely observed in electrocatalysis, but a detailed understanding of these changes at an atomic level is still lacking. In this study, we use a model atomically dispersed nickel catalyst to obtain a comprehensive view of potential-induced structure changes during the CO2 reduction reaction. Our findings show that the catalyst exhibits volcano-like selectivity changes that are dependent on the distance between the nickel atom and the carbon basal plane. Theoretical calculations suggest that local dynamic behaviors play a crucial role in regulating the distribution of the d band center of nickel.

Summary: Placental extracellular vesicles (EVs) play important roles in pregnancy, but they are also implicated in the progression of preeclampsia. A fabrication process called laser-induced nano-structuring of SERS-active thin films (LINST) was developed to produce substrates that allow the biochemical fingerprinting of EVs. The findings encourage the exploration of surface-enhanced Raman spectroscopy (SERS) of EVs as a promising method for preeclampsia liquid biopsies.

Summary: Machine learning has significantly impacted the value of spectroscopic characterization tools, especially in biomedical applications. However, the extensive data preprocessing required often introduces bias. To address this, researchers developed two deep learning methods capable of fully preprocessing spectroscopy data without human input. The findings suggest that these methods outperform conventional approaches in terms of speed, defect tolerance, and classification accuracy.

Summary: This study presents the design and implementation of a novel robotic soft esophagus (RoSEv2.0) for esophageal stent testing and food viscosity studies. The RoSEv2.0 is equipped with embedded time of flight (TOF) and pressure sensors for modeling and control. Model predictive control (MPC) using SINDYC models was implemented to autonomously govern peristalsis and air pressure. Successful generation of peristalsis waves and migration testing of stents were achieved.
