Sour soup, a traditional fermented specialty from Northeast China, is renowned for its distinctive aroma and various health benefits. Here, we report the probiotic properties of Lactiplantibacillus plantarum Z45—a strain isolated from sour soup broth—along with its fermentative potential in sour soup production. This strain is suitable for food fermentation due to its absence of biogenic amine production and non-hemolytic activity. It exhibited strong tolerance to simulated gastrointestinal conditions and demonstrated high adherence capability to Caco-2 cells. Additionally, the strain displayed antioxidant and antimicrobial activities. Whole-genome sequencing revealed that Z45 carries no virulence or antibiotic resistance genes. It also harbors multiple carbohydrate-active enzymes and a complete folate biosynthesis pathway, alongside genes associated with stress response, antioxidant activity, and adhesion. Subsequently, Z45 was employed as a starter culture for sour soup fermentation, and its effects on the physicochemical and sensory properties of the product were evaluated. The results indicated that fermentation with Z45 did not alter the physicochemical properties of sour soup but significantly enhanced its sensory attributes. Compared to spontaneous fermentation, Z45-fermented sour soup showed reduced levels of harmful biogenic amines, improved flavor and overall sensory quality, notable enrichment of Lactobacillus and Oscillospirales in the microbial community, and upregulation of beneficial metabolites such as flavonoids and glycerophosphocholine. In summary, Lactiplantibacillus plantarum Z45 is safe, demonstrates probiotic potential, and holds promise for improving the quality and functional properties of fermented foods. Full article

The increasing consumer demand for healthier food choices has stimulated research into functional bakery products enriched with bioactive ingredients. This review summarizes recent developments in the application of key polysaccharides—such as inulin and fructooligosaccharides (FOS), β-glucan, arabinoxylan, pectin, cellulose derivatives, resistant starch, maltodextrins, and dextrins—in bread, pasta, and fine bakery systems. Their incorporation affects dough rheology, fermentation behavior, and gas retention, leading to modifications in texture, volume, and shelf-life stability. Technologically, polysaccharides function as hydrocolloids, fat and sugar replacers, or water-binding agents, influencing gluten network formation and starch gelatinization. Nutritionally, they contribute to higher dietary fiber intake, improved postprandial glycemic response, enhanced satiety, and favorable modulation of gut microbiota. From a sensory perspective, optimized formulations can maintain or even improve product acceptability despite structural changes. However, challenges remain related to dosage optimization, interactions with the gluten–starch matrix, and gastrointestinal tolerance (particularly in FODMAP-sensitive individuals). This review summarizes current knowledge and future opportunities for creating innovative bakery products that unite technological functionality with nutritional and sensory excellence. Full article

Silicon dioxide nanoparticles (SiO2NPs) are widely used in various industries, raising concerns about their potential toxicity in aquatic organisms. Although several studies have investigated the general toxic effects of SiO2NPs, little is known about their impact on the nervous system and behavior of aquatic vertebrates. Furthermore, the combined assessment of behavioral, histological, and biochemical responses remains scarce. The study aimed to evaluate the effects of SiO2NPs on behavioral, histological, and biochemical parameters in adult zebrafish (Danio rerio). Fish were exposed to sublethal concentrations of SiO2NPs and their behavior was assessed using the social interaction test and the color preference test. Significant alterations in social behavior, such as reduced group cohesion and increased isolation tendencies, were observed. Additionally, exposed zebrafish exhibited a marked shift in color preference, indicating potential disruptions in sensory or cognitive function. Histological analyses revealed dose dependent tissue changes in brain structures, while biochemical assays indicated reduced activity of antioxidant enzymes, including catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx), suggesting elevated oxidative stress (OS). To the best of our knowledge, this is one of the first studies to integrate behavioral, histological, and biochemical endpoints in zebrafish to assess the neurotoxic potential of SiO2NPs. These findings suggest that SiO2NPs can induce histological alterations in brain structures, neurobehavioral changes, and OS in zebrafish, underscoring the novelty and relevance of this interdisciplinary approach, and the importance of further studies on SiO2NPs environmental and health impacts.

Background: Visual, vestibular, proprioceptive and cutaneous sensory information is important for postural control during quiet stance. When the reliability of one source of sensory information used to detect self-motion for postural control is reduced, there may be a reweighting of inputs within and/or across the remaining sensory systems determining self-motion for postural control. Muscle vibration, which creates an illusion of muscle stretch and a compensatory movement to shorten the vibrated muscle, may be used to determine the weighting of muscle spindle Ia proprioception in postural control. The objective of this study was to determine the effect of vision occlusion on triceps surae (TS) Ia proprioceptive weighting in postural control during quiet stance, utilizing an 80 Hz muscle vibration stimulus and a quantitative measure of the body’s anterior to posterior ground center of pressure (COP) response to TS muscle vibration in subjects standing freely. Methods: Subjects (N = 41; mean (standard deviation), 19.6(2.0) years) were examined as they stood with eyes open (EO) or eyes closed (EC). Ground COP was measured during quiet standing with and without bilateral vibration of the TS muscles. Results: The mean backward COP shift induced by TS vibration was significantly greater during the EC condition compared to EO (EC: −4.93(1.62) centimeters; EO: −3.21(1.33) centimeters; p = 6.85 × 10−10; Cohen’s d = 1.29). Thirty-seven subjects increased, and two subjects decreased their vibration-induced COP backward shift in the EC condition compared to EO, although the magnitude of the change varied. Conclusions: The results support the idea that, for most young subjects, there is an increased triceps surae Ia proprioceptive weighting for postural control during EC stance, possibly due to the need for postural control to depend more on non-visual feedback.

Corneal nerves play a crucial role in maintaining ocular surface homeostasis by supporting the functional integrity of corneal epithelial, stromal, and endothelial cells; modulating tear secretion; and facilitating sensory responses essential for overall ocular health. With advancing age, these highly specialized peripheral sensory fibers undergo progressive attrition and morphologic distortion driven by the canonical hallmarks of aging including genomic instability, impaired proteostasis, mitochondrial dysfunction, and chronic low-grade inflammation. The resulting neuro-immune dysregulation reduces trophic support, delays wound healing, and predisposes older adults to dry-eye disease, neurotrophic keratopathy, and postsurgical hypoesthesia. Age-exacerbating cofactors including diabetes, dyslipidemia, neurodegenerative disorders, topical preservatives, chronic contact-lens wear, herpes zoster ophthalmicus, and ocular-surface hypoxia further accelerate sub-basal nerve rarefaction and functional decline. This review provides an overview of age-related physiological alterations in ocular surface nerves, with a particular emphasis on corneal innervation. It also discusses risk factors that speed up these changes. Given the inherently limited regenerative capacity of corneal nerves and their inability to fully restore to baseline conditions following injury or degeneration, it is critical to identify and develop effective strategies aimed at mitigating or delaying physiological nerve degeneration and promoting nerve regeneration. This review also brings up emerging therapeutic strategies, including regenerative medicine, neuroprotective agents, and lifestyle interventions aimed at mitigating age-related corneal nerve degeneration.

This study explores the use of a homemade mung bean protein extract solution (MP) as the moisture source in high-moisture extrusion to produce pea–mung bean composite textured protein (PMP). Single-factor experiments assessed the effects of MP addition amount (30–70%), screw speed (140–220 rpm), and extrusion temperature (140–180 °C) on the textural, physicochemical, and structural properties, followed by optimization using response surface methodology (RSM). MP addition amounts between 50% and 60% promoted higher surface hydrophobicity, a higher disulfide bond content, more ordered secondary structures, and a higher intrinsic fluorescence, accompanied by improved water- and oil-holding capacities, bulk density, and texturization degree (p < 0.05). Screw speeds of 160–180 rpm enhanced texturization and texture via increased shear and reduced residence time, whereas higher extrusion temperatures darkened the color (Maillard browning) and reduced texturization and the bulk density. RSM found that the optimal conditions were 53% MP, 160 rpm, and 150 °C, yielding a theoretical maximum texturization degree of 1.55, which was experimentally validated (1.53 ± 0.02). These findings support MP as an effective green moisture source to tailor the structure and functionality of pea-based high-moisture extrudates. Future work will integrate calibrated SME, sensory evaluation, and application testing in meat-analog formats. Full article

Aging involves a progressive decline in physiological functions, increasing vulnerability to disorders, functional decline, and disability. Emphasizing resilience and intrinsic capacity offers a proactive framework for promoting successful aging and quality of life. This narrative review selected significant articles published within the last five years on resilience, especially physical resilience, and intrinsic capacity, along with earlier relevant works. Articles were primarily searched in English using PubMed, Google Scholar, and Scopus, employing relevant terms with Boolean operators (“AND”, “OR”). Inclusion criteria included peer-reviewed conceptual, observational, and interventional studies on resilience and/or intrinsic capacity in adults over 60, published between 2020 and 2025, highlighting how the inclusion of geriatric evaluation improves health outcomes. Studies not focused on older adults, outside the date range, or non-English articles were excluded. Out of 145 references, 43 articles met the inclusion criteria. ResEvidence suggests that resilience (a dynamic response to stressors) and intrinsic capacity (baseline reserves across locomotion, vitality, cognition, sensory, and psychological domains) are interconnected, with resilience being associated with better health outcomes, a lower prevalence of chronic diseases, and greater mental health stability. Incorporating assessments of resilience and intrinsic capacity into clinical workflows could support targeted interventions; routine screening may guide personalized exercise and psychosocial plans to help prevent functional decline. Utilizing brief, validated tools (e.g., Short Physical Performance Battery, handgrip strength, Geriatric Depression Scale, brief cognitive tests, and resilience scales) can inform interventions such as physical activity, nutritional support, deprescribing, and psychosocial engagement, which may support healthier aging trajectories.

Consumer interest in alternative protein sources has grown rapidly, driven by concerns over health, sustainability and environmental impact. This study investigated perceptions, attitudes and behaviours towards alternative proteins among residents of Piedmont, northwestern Italy. A cross-sectional online and face-to-face survey was conducted between August and October 2023, collecting sociodemographic data, dietary habits, and respondents’ perception on plant-, insect-, snail-, and algae-derived products. Responses from 627 participants were analysed. Approximately one-third reported consuming alternative proteins, with uptake being higher among women, younger adults, and flexitarian respondents. Plant-based alternatives were by far the most frequently consumed, while insect- and snail-based products elicited strong aversion. Curiosity and interest on alternative options predominated among consumers, whereas indifference and disgust—particularly among women and towards animal-derived options—were common among non-consumers. Reported barriers included taste, quality, and safety concerns, with price emerging as a major constraint. These findings indicate that acceptance of alternative proteins is unevenly distributed across demographic groups and product types. Plant-based options currently appear best positioned to facilitate dietary shifts, whereas animal-derived alternatives remain hindered by cultural and sensory barriers. Supporting the protein transition will require strategies to improve affordability, sensory appeal and consumer trust. Full article

Auditory cues are an important, though often overlooked, component of the multisensory experience of food consumption, directly influencing consumer perception and enjoyment. This study investigates how prior food-related experiences affect the perception and preference for food sounds, with a focus on artisanal bread, a popular staple food with distinctive auditory characteristics. A group of 113 participants was recruited and assigned to one of the two groups: 53 attended a bread-making workshop to establish enriched audiovisual associations, while 60 watched bread-making videos online, which represented a comparatively limited form of sensory engagement. Participants rated their perceived comfort levels for three distinct bread-related food sounds before and after the intervention. Sound recognition performance was also assessed as well as the appeal of the sounds. The results revealed that those who attended the workshop evaluated the close-up food sounds significantly more positively than those who watched the videos instead. Furthermore, regression analyses revealed that greater visual involvement during the workshop/watching videos was associated with increased comfort and decreased annoyance for the close-up bread sounds. These findings underscore the importance of multisensory integration experiences, particularly audiovisual integration, in shaping consumer responses and preferences for food sounds. To make sure that consumers feel comfortable and even hungry when they listen to food-related audial content, it is beneficial to incorporate familiar food sounds and, where possible, reinforce these with visual or experiential cues. Content that leverages multisensory associations and aligns with listeners’ prior experiences is likely to be more effective in eliciting positive sensory and emotional responses. Full article

The postharvest behavior of two peach varieties (Pavía Canario and Moscato Tardío) was evaluated during 30 days of refrigerated storage at 0 °C followed by 5 days at 20 °C (shelf life). Firmness, respiratory activity, sugar content, total polyphenol content (TPC), total antioxidant capacity (TAC; ferric reducing antioxidant power, FRAP; 2,2-diphenyl-1-picrylhydrazyl, DPPH; and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid), ABTS), and sensory attributes were assayed. Respiratory activity peaked around day 15 in both varieties, with Moscato Tardío showing higher values than Pavía Canario, reflecting differences in cold stress response. During refrigerated storage, Moscato Tardío maintained higher firmness (36.1 N) than Pavía Canario (27.2 N), although firmness decreased by ~30% after transfer to shelf life. Glucose and sucrose contents were higher in Moscato Tardío, while Pavía Canario showed higher initial TAC (FRAP: 117.2 mg ascorbic acid equivalents AAE·kg−1; DPPH: 472.8 mg AAE·kg−1). TPC increased over time in both varieties, but with different dynamics: Pavía Canario peaked at 20 days, whereas Moscato Tardío increased markedly at 30 days. ABTS values varied intra-varietally, showing maximum differences during storage. Sensory evaluation indicated better juiciness and reduced mealiness in Moscato Tardío throughout storage and shelf life. Overall, postharvest responses were genotype-dependent: Pavía Canario activated antioxidant defenses earlier, while Moscato Tardío exhibited delayed but substantial responses, maintaining firmness and sugar content, and better overall sensory quality.

The traditional use of iced trash fish (IF) in Chinese mitten crab (Eriocheir sinensis) aquaculture raises sustainability concerns, but the shift to formulated feeds (FF—a commercial compound feed specifically designed to meet nutritional requirements by blending multiple ingredients and containing a balance of nutrients) is often hindered by fears of compromising its prized flavor. This study aimed to comprehensively evaluate whether a commercial formulated feed could effectively replace IF without diminishing flavor quality, hypothesizing that FF would alter the intestinal volatile profile, thereby influencing muscle flavor. Male crabs were fed either IF or FF for eight weeks. Muscle flavor was assessed using sensory evaluation, electronic nose (E-nose), and gas chromatography–ion mobility spectrometry (GC–IMS). Volatile compounds in intestinal chyme were also analyzed by GC–IMS to explore potential transfer mechanisms. The results indicated that crabs fed with FF showed higher sensory scores for sweetness. Additionally, the E-nose analysis revealed a clear separation trend between dietary groups and showed markedly higher sensor response values for aromatic compounds, biogenically derived compounds and Maillard reaction products, sulfur-containing organic compounds, aliphatic hydrocarbons, total volatile organic compounds, alcohols and organic solvents, and alkenes in the FF group compared to the IF group. Thirty-four volatiles were discovered in the muscle. Statistical analysis (independent samples t-test) showed that the FF group exhibited significantly elevated levels of 3-methylbutanal-M, propanal, (E)-2-pentenal, 2,3-pentanedione, and pentan-1-ol-M, whereas the IF group exhibited significantly elevated levels of 2-hexanone, dihydro-2(3H)-furanone, butyl acetate, ethyl 2-methylpropanoate, and phenol (p < 0.05). Fourty-eight volatiles were identified in the intestinal chyme. Propanal and ethyl 2-methylpropanoate were the dominant odor contributors based on correlation network analysis. Strong correlations were identified between the flavor profiles of intestinal chyme and muscle, suggesting a potential transfer or transformation of volatiles. This work provides a scientific basis for optimizing aquafeed formulations to ensure sustainable crab production without sacrificing end-flavor quality. Full article

Background/Objectives: Fibromyalgia (FM) is a nociplastic pain disorder marked by altered central nervous system processing and abnormal sensory modulation. Diagnosis remains largely symptom-based and lacks objective biomarkers. Sensory modulation disorder (SMD)—impaired regulation of responses to non-noxious input—may represent a clinically relevant diagnostic dimension. This study aimed to estimate the prevalence/diagnostic value of SMD in FM, examine links with symptom severity and stress, and assess its potential for patient stratification. Methods: In this cross-sectional study, 182 adults were enrolled (104 FM; 78 controls). Standardized instruments included the Adolescent/Adult Sensory Profile (AASP), Fibromyalgia Impact Questionnaire (FIQ), and Perceived Stress Scale (PSS). Group comparisons, regression, and discriminant analyses evaluated SMD profiles. Results: Compared with controls, FM adults showed higher sensory sensitivity and avoidance (both p < 0.001), lower sensation seeking (p = 0.002), and modestly higher low registration (p = 0.027). Elevated SMD correlated with greater symptom severity and perceived stress. Stress significantly predicted FM’s impact (β = 0.57, p < 0.001). A discriminant model achieved 84% apparent in-sample accuracy for classifying FM severity from sensory/stress profiles. Conclusions: Sensory modulation abnormalities are highly prevalent in FM and show meaningful associations with symptom severity and stress, suggesting that SMD could represent a potential diagnostic dimension and stratification aid. These findings should be interpreted within an exploratory, cross-sectional design. Incorporating sensory modulation assessment into FM evaluation may improve diagnostic precision, reduce delays, and guide individualized management. Confirmation in larger longitudinal studies is warranted. Full article

Traditionally used to combat infections, systemic effects of antibiotics are increasingly recognized in the context of absorption through unconventional routes. One such as the ocular surface. This review tackles the bidirectional liver–eye axis, highlighting how trace antibiotic residues from environmental and therapeutic sources affect the tear film, disturb ocular microbiota, and impact liver metabolism. It engages in anatomical pathways, microbial regulation, pharmacokinetics, and systemic immune responses. Additionally, this review discusses forensic uses and new therapeutic strategies, stressing the importance of integrated environmental monitoring and precision medicine to tackle nonmedicinal antibiotic exposure. Due to the absence of results from a systematic literature review, a narrative literature review was undertaken instead. More than 100 studies discussing mechanistic, clinical, and experimental insights were reviewed, with 98 of those studies being documented as source literature. The findings demonstrate that antibiotics may penetrate and be absorbed through the ocular surface, cause modifications of the hepatic first-pass metabolism, and change the activity of cytochrome P450. Correlations were documented between the various liver function biomarkers and the ocular tear film, as well as the thickness of the retinal pigment epithelium. The dysbiosis of eye microbiota may be an indicator of systemic inflammation associated with immune dysregulation. Restoring microbial homeostasis and addressing systemic dysregulation are novel therapeutic approaches, including the use of probiotics, nanoparticle scavengers, and CRISPR. The eye is a sensory organ and a metabolically active organ. Systemically, the eye can affect the liver through the ocular surface and the antibiotics through the liver–eye axis. To protect the systemic health of the individual and the lensed metabolically active eye, the eye and liver must be viewed as a sentinel of systemic balance. Novel therapies will be necessary with the added need for environmental monitoring. Full article

As part of urban sustainable food strategies, reducing land and emission footprints motivates interest in edible insects (EI) as a sustainable protein source. However, research on the determinants of young consumers’ acceptance and willingness to pay for insect-based foods in Central and Eastern Europe remains limited. This study assessed whether Polish students are willing to pay more for foods containing EI when production is environmentally friendly. The analysis focused on identifying socio-demographic and product-related factors influencing willingness to pay a higher price. Data were collected in November 2023 through a nationwide Computer-Assisted Web Interview (CAWI) conducted via Google Forms among 947 Polish university students. A logistic regression model was applied to determine socio-demographic predictors, while exploratory factor analysis was used to identify latent dimensions of product attributes and food categories. Results revealed that gender and place of residence significantly affected willingness to pay, with women and urban residents showing higher readiness. Attributes related to convenience, availability, sensory appeal, health and nutrition claims, and CO2 reduction benefits were the strongest positive correlates. The findings suggest pragmatic pathways for introducing insect-based foods into sustainable urban food systems and highlight the role of education in fostering environmentally responsible consumer behavior.

Abstract
Background/Objective: Riboflavin transporter deficiency (RTD) is a rare neurodegenerative disease, with under 500 cases genetically confirmed since the early 2000s. Thus far, three separate subtypes of RTD2 are described—type 1, 2 and 3—but, previously, RTD was classified as two separate genetic defects: Brown–Vialetto–Van [...] Read more.
Background/Objective: Riboflavin transporter deficiency (RTD) is a rare neurodegenerative disease, with under 500 cases genetically confirmed since the early 2000s. Thus far, three separate subtypes of RTD2 are described—type 1, 2 and 3—but, previously, RTD was classified as two separate genetic defects: Brown–Vialetto–Van Laere syndrome and Fazio–Londe syndrome, caused by mutations in the SLC52A2 and SLC52A3 genes, respectively. The most prominent symptoms found in patients include encephalopathy, expressed as peripheral and cranial nerve neuropathy, which in turn lead to a series of complications: decreased muscle strength, hypotonia, visual impairment, sensorineural hearing loss, bulbar palsy, sensory ataxia and respiratory insufficiency secondary to diaphragmatic paresis. At the cellular level, riboflavin is modified into active flavin cofactors: FMN, mediating riboflavin phosphorylation through riboflavin kinase, and FAD, involved in FMN adenylation through the flavin dinucleotide 1 synthesis. FMN and FAD are two of approximately 100 proteins collectively described as the ‘flavoproteome’. Most of them are mitochondrial oxidoreductases, catalyzing the electron transport in many metabolic reactions, as well as regulating important cell processes, such as the production of reactive oxygen species, protein conformation and damage repair. FMN and FAD are also responsible for the conversion of B6 and B9 vitamins into their active forms, which allows for healthy cell growth and immune function. Methods: In this article, the authors describe two children, a 6-year-old girl and her 5-year-old sister, both presenting with RTD2 caused by mutations in the SLC52A2 gene (c.916G>C (p.Gly306Arg); c.477C>G (p.Cys159Trp)), in whom the disease progression was successfully inhibited by vitamin B2 supplementation in varying doses. Results: Their clinical image consists of psychomotor developmental delay, ataxia, horizontal nystagmus, hearing loss and a lack of visual fixation. Conclusions: The phenotype and clinical signs presented by the described sisters are further discussed in relation to the previously published reports of RTD2 cases. Full article
