Evaluation of turkey liver pate and cannerd turkey ham quality through sensory, chemical and microbiologica analyses
(Alma Mater Publishing House, 2026-03-27) Davidescu, Mădălina-Alexandra; Simeanu, Cristina; Mădescu, Bianca-Maria; Usturoi, Alexandru; Doliș, Mariu-Gheorghe; Lăpușneanu, Dragoș-Mihai; Pânzaru, Claudia
This study aimed to compare two canned turkey meat products, respectively turkey liver pâté and canned turkey ham, through sensory, physico-chemical, and microbiological analyses. Sensory evaluation was conducted using a 5-point scale across five parameters (appearance, color, taste, texture, and packaging), assessed by 12 panelists. The canned turkey ham achieved a higher average score (18.17 out of 25 points) compared to the liver pâté (17.25 out of 25 points), mainly in terms of texture and color. Physicochemical determinations included measurements of sodium chloride (NaCl), nitrites (NO2-) moisture, protein, and fat. The liver pâté presented higher fat content (24.80 g·100 g-1), nitrites (5.64 mg·100 g-1), and greater variability in moisture content (62.79-71.14 %), while the canned ham showed lower fat (3.92 g·100 g-1), higher protein (14.80 g·100 g-1), and more uniform composition. Both products were within the acceptable limits for NaCl content (1.35 g·100 g-1 in pâté; 1.19 g·100 g-1 in ham). Microbiological tests confirmed the absence of Salmonella spp. and Escherichia coli in all samples. Hermetic sealing was verified, indicating compliance with food safety requirements. In conclusion, both products meet quality and safety standards, but the canned turkey ham demonstrates better nutritional balance and technological consistency, while the liver pâté may benefit from improved standardization of fat, moisture, and salt content.

Oxytocin modulates social preference and anxiety-like locomotor behavior in albino and non-albino zebrafish
(Association of Basic Medical Sciences of Federation of Bosnia and Herzegovina, 2026) Dănilă, Ana-Maria; Savuca, Alexandra; Nicoară, Mircea-Nicușor; Ciobîcă, Alin-Stelian; Novac, Bogdan; Chiriac, Ștefan; Tomiță, Daniela; Ilie, Ovidiu-Dumitru
Socio-emotional and exploratory behaviors in zebrafish (Danio rerio) are shaped by conserved neuromodulators such as oxytocin (OXT), yet phenotypic variation (e.g., albinism) may modify sensitivity to OXT-dependent regulation. Here, we tested whether pigmentation phenotype alters behavioral responses to acute OXT across structured social and anxiogenic contexts. Adult albino (A; n = 30) and non-albino (N; n = 30) zebrafish (total n = 60; equal allocation across 6 groups, n = 10/group) were exposed to OXT by immersion (33.2 ng/mL, 15 min) under a 2 × 3 factorial design (Phenotype × Dosing regimen: Vehicle; OXT single exposure assessed at 24 h; OXT repeated exposure assessed at 48 h) and evaluated using the social preference test (SPT), social interaction (SI) test, and novel tank test (NTT). In the SPT, decision-zone occupancy and mean distance to the non-social arm were robustly modulated by dosing (p < 0.0001; p = 0.007) without phenotype × dosing interactions; locomotor outputs (swimming distance, p = 0.040; velocity, p = 0.041; counterclockwise rotations, p = 0.006) also showed dosing effects only, supporting a dissociation between social allocation and global motor output. In the SI test, stimulus-zone occupancy showed a significant main effect of phenotype (p = 0.009), independent of dosing, and locomotor indices similarly exhibited phenotype effects without interaction (swimming distance and velocity, p = 0.017; mobile-state duration, p = 0.002). In contrast, the NTT revealed phenotype-dependent locomotor regulation: highly mobile duration showed a significant interaction (p = 0.002) with strong main effects of phenotype and dosing (both p < 0.001), while immobile duration displayed an interaction (p = 0.015) and dosing effect (p = 0.005), driven primarily by the non-albino phenotype; clockwise rotation (p = 0.018) and active-state duration (p = 0.030) further indicated phenotype-related differences. Collectively, OXT exerts context- and dosing-regimen-dependent modulation in zebrafish, with social allocation primarily dosing-driven and largely phenotype-independent, whereas anxiety-related locomotor dynamics show marked phenotype specificity.

Some of the Newest Therapeutic Methods in Canine Atopic Dermatitis
(MDPI, 2026-04-20) Mazilu, Constantin-Cătălin; Strichea, Anamaria-Hortensia; Solcan, Gheorghe
Canine atopic dermatitis is a hereditary chronic inflammatory and pruritic skin disease, which is mediated by T cells and requires long-term, individualized management. In recent years, numerous studies have described a wide range of therapeutic approaches for canine atopic dermatitis, including fast-acting symptomatic treatments, long-term immune-modulating interventions, and strategies to support skin barrier function and microbial balance. This review summarizes the principal treatment modalities currently available, including glucocorticoids, cyclosporine A, mycophenolate, Janus kinase inhibitors, lokivetmab, and allergen-specific immunotherapy, as well as complementary strategies aimed at restoring skin barrier integrity. Emphasis is placed on the importance of a multimodal and personalized approach to optimize long-term disease control and improve quality of life in affected dogs. Providing an integrated overview of current evidence, this article aims to guide clinicians in making informed, evidence-based decisions and to support the safe and effective management of canine atopic dermatitis.

Micro- and Nanoplastics as Drivers and Modulators of Hepatotoxicity in Zebrafish (Danio rerio): Interactions with Environmental Co-Contaminants and Molecular Mechanisms
(MDPI, 2026-05-28) Szilagyi, Alexandra; Jităreanu, Alexandra; Olărița, Alina Iliuța; Solcan, Carmen
Micro- and nanoplastics (MNPs) have emerged as pervasive contaminants in aquatic ecosystems, raising concerns regarding their biological impacts on aquatic organisms. The liver plays a central role in metabolism, detoxification, and immune regulation, making it particularly vulnerable to MNP-induced toxicity. Importantly, MNPs also function as vectors and modulators of co-occurring environmental contaminants, including heavy metals, pesticides, antibiotics, PFASs, algal toxins, and polycyclic aromatic hydrocarbons (PAHs), thereby influencing contaminant bioavailability and hepatic toxicity. This narrative review synthesizes current evidence on hepatic alterations induced by micro- and nanoplastic exposure in zebrafish (Danio rerio), with emphasis on histopathological changes and underlying mechanisms. Relevant peer-reviewed studies were identified through systematic searches of Web of Science, Scopus, PubMed, and ScienceDirect, covering the period 2013–2026, and screened according to predefined inclusion criteria focusing on hepatic endpoints in zebrafish exposed to micro- and nanoplastics. Across the available literature, MNPs consistently accumulate in hepatic tissue and induce structural alterations, including hepatocellular vacuolization, steatosis, inflammatory infiltration, and necrosis. Mechanistically, these pathological changes are closely linked to oxidative stress, impairment of antioxidant defense systems, reprogramming of lipid and glucose metabolism, and activation of inflammatory and regulated cell death signaling pathways. In addition, interactions with co-occurring environmental contaminants—such as heavy metals, pesticides, antibiotics, and algal toxins—frequently exacerbate hepatic injury through synergistic toxicological mechanisms. Disruption of the gut–liver axis and intestinal microbiota has also emerged as an important contributor to systemic metabolic and inflammatory responses. Overall, zebrafish studies demonstrate that the liver represents a critical target organ for MNP toxicity. Future research should prioritize environmentally realistic exposure scenarios, standardized particle characterization, and integrated multi-omics approaches to improve ecological and human health risk assessment.

Stress in Free-Roaming and Shelter-Housed Dogs: A Review of Neurobiological, Physiological and Behavioral Mechanisms Relevant to Welfare Assessment
(MDPI, 2026-07-14) Rotaru, Gheorghița; Hrițcu, Teodor-Daniel; Mălăncuș, Răzvan-Nicolae; Hrițcu, Luminița-Diana; Soponaru, Camelia; Nechifor, Florin; Boghian, Vasile; Cherșunaru, Alexandra Andreea; Munteanu, Alexandru; Spătaru, Mihaela-Claudia
Stress is a major influencing behavior, health, and welfare in free-roaming dogs, particularly in environments characterized by unpredictability, social instability, and frequent human interactions. Although research on canine stress responses has expanded considerably, current knowledge remains fragmented across the neurobiological, physiological, and behavioral domains, limiting the development of comprehensive welfare assessment strategies. Importantly, free-roaming and shelter-housed dogs should not be viewed as entirely separate populations, since many shelter dogs originate from free-roaming environments and share similar stress-related experiences. This narrative review provides a comprehensive synthesis of current evidence on stress mechanisms in free-roaming and shelter-housed dogs The literature was explored across major scientific databases, and a total of 69 relevant studies were included. Particular emphasis was placed on the activation and regulation of the hypothalamic–pituitary–adrenal (HPA) axis, associated neuroendocrine alterations, and their behavioral expression. The strengths and limitations of commonly used physiological indicators, including cortisol measured in blood, saliva, feces and hair, were critically examined in relation to their applicability in real-world contexts. Behavioral manifestations of stress, such as fear- and anxiety-related responses, aggression, withdrawal, and stereotypic behaviors, were analyzed as functional outcomes of neurobiological activation and environmental challenges. Environmental stressors typical of shelter conditions as well as the role of human–dog interactions in stress modulation are also discussed. By combining neurobiological, physiological, and behavioral perspectives, this review highlights the importance of multidimensional stress assessment and proposes a conceptual framework linking biological mechanisms with observable behavioral indicators of welfare across the continuum from free-roaming to shelter environments. These findings may support the development of evidence-based welfare assessment and management strategies for free-roaming and shelter-housed dog populations.
