Summary: The sensing of amino acids in the fish brain, particularly branched-chain amino acids like leucine, plays a role in regulating feed intake through various mechanisms. Studies suggest that members of the SLC family may be involved in the anorectic effect of leucine and serve as an additional amino acid sensing mechanism in fish regulation of feed intake, particularly in brain areas such as the hypothalamus and telencephalon. The different paralogues of amino acid carriers, including LAT1 and SNAT2, showed changes in mRNA abundance in response to varying levels of leucine in the diet in Atlantic salmon.

Summary: Orexins play a crucial role in regulating eating behavior beyond homeostatic feeding, including reward and motivation. Studies have shown the involvement of orexins in hedonic and appetitive behavior towards palatable food. There is a bias towards studies involving male subjects in the literature, highlighting the need for future research to include female subjects.

Summary: Understanding the neural circuit mechanisms underlying feeding behaviors is important for identifying therapeutic targets for food-related disorders. Homeostatic and non-homeostatic appetites interact through neural circuits to promote feeding behaviors. Recent breakthroughs in research techniques have accelerated the discovery of these neural circuits.

Summary: This paper argues for a biological conception of music listening as an evolutionary achievement related to cognitive and emotional functions grounded in basic homeostatic regulation. Listeners are conceived as open systems continuously interacting with the sonic world, trying to maintain a controlled state of dynamic equilibrium by seeking out beneficial stimuli and avoiding harmful ones.

Summary: A sedentary lifestyle and high-fat diets contribute to the rapid growth of type 2 diabetes mellitus. The mediobasal hypothalamus plays a crucial role in detecting nutritional cues and regulating glucose production. Negative environmental factors can impair these adaptive responses and contribute to the development of metabolic diseases.

Summary: The study found that neural sensitivity to repeated hedonic rewards is more prone to decrease over time compared to eudaimonic rewards. Furthermore, a decline in sensitivity to repeated eudaimonic rewards is marginally associated with longitudinal decreases in well-being. Sustained eudaimonic reward sensitivity in the short term has greater implications for changes in well-being in the long term.

Summary: The gut microbiota plays a key role in modulating host physiology and behavior, particularly in relation to feeding behavior, energy balance, and obesity. Changes in microbiome composition due to diet can lead to weight gain, adiposity, and alterations in ingestive behavior. Research is focused on understanding the role of the microbiome in the development of obesity and using microbiome manipulation to reduce food intake and promote weight loss.

Summary: This study reports the construction of nanoassemblies through coassembly of an amphiphilic amino acid and hemin, which allows tailored peroxidase-mimicking activities. The optimized nanoassemblies exhibit remarkable catalytic efficiency and robustness in multiple catalytic cycles, and can be effectively integrated into a sensing system for catalytic detection of glucose.

Summary: This study proposes a new THz sensing method based on THz reflective time-domain polarization spectroscopy system and chiral metasurface sensor, which improves sensitivity and detection accuracy for amino acid aqueous solutions. The sensing accuracies reach 10(-5) × 10(-4) g/mL, and D- and L- enantiomers with the same concentration can be distinguished.

Summary: This study examined how biometric responses differ in foods varying in fat and taste, and found positive associations between attention and subsequent food reward and intake. The findings suggest that implicit biometric responses to food cues can predict both food reward and actual food intake.

Summary: Orexin peptides, including orexin A and orexin B, interact with orexin receptor 1 and orexin receptor 2 to regulate various functions in the body, such as feeding behavior, reward-seeking behavior, cognition, and mood. Dysregulation of orexin signaling has been implicated in mood disorders and addiction, while orexin also plays a key role in regulating behaviors in motivationally charged situations, such as seeking food or drugs. Further studies are needed to investigate the association between orexin and changes in hedonic tone.

Summary: Understanding the regulation of food intake in fish is crucial for formulating aquafeeds. This study evaluated the short- and mid-term response of European sea bass fed diets with partial and total fishmeal replacement by defatted Tenebrio molitor larvae meal (dTM). The results showed that dTM replacement did not affect food intake regulation in sea bass, but may lead to long-term changes in intermediary metabolism.

Summary: This study aimed to investigate the amino acid sensing capacity and hormone production in the gastrointestinal tract (GIT) of rainbow trout in response to proline, fishmeal amino acids, and fishmeal aqueous extract. The results showed that the presence of proline in the GIT led to changes in amino acid sensing systems and hormone production, especially in the proximal regions, accompanied by anorectic response in the hypothalamus. Both the fishmeal aqueous extract and the fishmeal amino acids induced anorectic responses in the hypothalamus, accompanied by increased production of anorectic hormones in the intestine.

Summary: To improve fish welfare, aquafeeds should be designed to help fish cope with the stressful conditions of fish farms. One effective strategy is to supplement the diet with bioactive hydrolysates. This study investigated the supplementation of European seabass diet with swine blood hydrolysates to modulate oxidative stress and found that nanofiltration-treated hydrolysates may reduce oxidative stress in fish.

Summary: This study aimed to investigate the potential role of insulin as an intake signal mediating liver entrainment in fish. The experiments showed that the presence of insulin directly increased the abundance of per1a and per2 transcripts in the fish liver. It was found that the involvement of the PI3K/AKT pathway is crucial for insulin-mediated liver entrainment.

Summary: In the past decade, the zebrafish has become an important model organism for studying behavior, neurological disorders, and metabolic diseases. This study used the zebrafish model to investigate how obesity induced by overfeeding affects emotional and cognitive processes. The results showed that obesity impaired short-term memory in zebrafish, but had no effect on anxiety-like behavior.

Summary: This study evaluated the impact of partial and total fishmeal replacement by insect meal on intermediary metabolism of European sea bass. The results showed that the selected insect meal can replace 50% of fishmeal without adversely affecting liver health or intermediary metabolism. However, total fishmeal replacement may compromise fish health in the long-term.
