Summary: Through studying fruit flies, we have found that multimodal sensory integration plays a role in feeding behavior, particularly the contributions of olfactory and mechanical inputs to taste-evoked feeding behavior. Controlled delivery of three different sensory cues can produce a supra-additive reflex. Fruit flies serve as a versatile model system for studying multisensory integration related to feeding, which likely also exists in vertebrates.

Summary: The study aims to understand the differences in flavor of fresh milk between feeding patterns. Aroma profiles and taste attributes were assessed using electronic nose and electronic tongue, and volatile flavor compounds were characterized. Different volatile compounds were found in milk from indoor feeding and grazing, with grazing milk having more intense taste attributes. This study shows promise for using volatile organic compounds to track and monitor animal feeding systems.

Summary: Glutathione transferases (GSTs) are key enzymes that have a wide range of activities as transferases or isomerases. They play important roles in both detoxification and modulation of the perception process in chemosensory organs. By metabolizing exogenous molecules, GSTs contribute to signal termination and modulate receptor activation, ultimately affecting the perception of these molecules. This review provides insights into the involvement of GSTs in chemoperception, discussing their localization and enzymatic capacity in insects and mammals.

Summary: There is a significant demand in the food industry for natural flavors, but many flavor molecules are unstable outside their original sources. Understanding the link between food processing conditions and flavor generation is crucial for stability. Garlic and chili flavors can be generated through thermal processing, with capsaicinoids being reported as a thermally stable chili pepper flavor.

Summary: Tea, as one of the most important beverages globally, has influenced lifestyles and promoted the exchange between the East and West as it spread from the East to West. Tea processing, which includes multiple steps, has a critical impact on tea flavor development. With the development of mechanical processing, tea is now widely produced by both hand-crafting and mechanical processing. Modern separation techniques have also allowed the acquisition of various components of tea. In traditional Chinese medicine, tea has long been recognized for its beneficial effects on health, and modern medical and nutritional studies have confirmed its ability to lower blood lipids, blood sugars, as well as its anti-inflammatory and anti-oxidative properties. Bridging historical knowledge on tea with modern technology and science through interdisciplinary theories, methods, and techniques will contribute to further understanding tea.

Summary: In extended Higgs models, a discrete symmetry is required in the quark sector, but not necessarily in the lepton sector. We present a four-doublet model where one Higgs couples to quarks and three others couple to the electron, muon, and tau. The model is studied with various constraints and it is shown that the lighter additional scalars can decay into electrons and muons.

Summary: Seafood processing requires appropriate technologies to improve or maintain its quality, especially in terms of flavor. This review provides updated information on traditional and emerging processing technologies and their implications on flavor. Traditional thermal treatment effectively deactivates microorganisms but comes with limitations. Emerging technologies like microwave heating, infrared heating, and ultrasound not only deactivate microorganisms and extend shelf life, but also safeguard the sensory quality of seafood.

Summary: This study investigates the effects of olfactory and gustatory stimuli on feeding behavior, expression of neuropeptide Y (NPY), and feed intake in yellowtail. The results suggest that olfactory stimulation promotes "search" behavior through npy mRNA expression, while taste stimulation promotes "bite" behavior and increases feed intake. However, odor stimulation does not increase feed intake, whereas taste stimulation does.

Summary: Nasal airflow is critical in olfactory processes, and monitoring nasal air pressure using a lightweight, open-source brain-computer interface system can help understand odor sampling behavior. The study found that during an oral fluid discrimination task, patterns of retronasal airflow varied and the duration, probability, and estimated volume of retronasal airflow were greater during discrimination of perceptually similar solutions.

Summary: The study explores category-specific and category-general neural codes of recognition memory in the visual pathway. The results indicate that the fusiform face area (FFA) and parahippocampal place area (PPA) show category-specific neural patterns for recognition memory of faces and scenes, respectively. The lateral occipital cortex carries category-general neural codes of recognition memory.

Summary: Anopheline mosquitoes rely on their chemosensory apparatus to detect chemical stimuli. The ionotropic coreceptor AcIr76b plays a role in the mosquito's olfactory and gustatory systems. Mutants without AcIr76b show enhanced responses to amines and reduced responses to acids and other amines. Furthermore, these mutants have decreased insemination capability and are unable to successfully blood feed.

Summary: The study aimed to investigate the differences in quality of life among patients with olfactory dysfunction of different origin. Results showed that patients with post-infectious and post-traumatic OD had poorer olfactory-related QOL. Olfactory-related QOL was positively associated with olfactory function, disease duration, age, and negatively associated with being female.

Summary: The study found that besides changes in the olfactory cortex after head trauma, other cortical areas play a significant role in olfactory impairment. The neural responses and connectivity in higher-order areas have complex relationships with olfactory perceptual function, which can help distinguish functional anosmia from normosmia.

Summary: This study aimed to replicate previous findings that individuals with healthy weight bid the most for combo foods, but this effect was not seen in those with overweight/obesity. Additionally, contrary to previous reports, there was a negative relationship between the actual energy density of snacks and bid amount, which was mediated by food price. These findings suggest altered macronutrient reinforcement in obesity and highlight potential influences of the food environment on food reward regulation.

Summary: The frequent association between COVID-19 and olfactory dysfunction is leading to a demand for treatment, with systemic corticosteroids considered as an option. However, caution is advised due to weak evidence supporting their effectiveness, high rate of spontaneous recovery, and potential adverse effects. Instead, smell training, which has strong evidence and no known side effects, should be considered initially.

Summary: This study retrospectively analyzed the symptoms, signs, and radiological and intraoperative descriptions of chorda tympani nerve (CTN) involvement in 73 patients with external auditory canal cholesteatoma (EACC). The results showed that 10 out of 73 patients experienced subjective dysfunction, and 8 had abnormal taste test results. The discussion and conclusion suggest that CTN dysfunction often develops asymptomatically in chronic ears, but up to one out of 10 EACC patients with advanced disease may experience regional gustatory dysfunction prior to surgery.
