Abstract	BACKGROUND: An innovative pilot‐plant packaging was developed and evaluated for applying oregano essential oil (OEO) vapours in conditions of high vacuum for exploring the antimicrobial effect of essential oil vapours applied immediately before packaging of fish fillets. Farmed sea bream (Sparus aurata) fresh fillets have been used as a model for validating this new technology. These fillets, as a refrigerated product under modified atmosphere packaging (MAP), have a relatively short shelf life (12–14 days) mainly due to the fast microbial growth. The effects of conventional OEO dippings [pretreatment dipping (0.1% of OEO) of whole fish (T1) and filleted sea bream (T2)] were compared with the OEO application in vapour phase (67 μL L‐¹) under vacuum (5–10 hPa) immediately before MAP fillet packaging (T3). RESULTS: T3/T2 samples showed the lowest microbial growth after 28 days at 4 °C, with loads up to 1/2.6 log units for Enterobacteria/lactic acid bacteria compared to untreated samples. The initial trimethylamine nitrogen (TMA‐N) content (2.6 mg kg⁻¹) increased in T1 and T2/T3 samples by 9.6 and 6/7 units, respectively, after 28 days. Quality Index Method (QIM) better reflected the fish fillets shelf life than texture and colour measurements. The shelf life of T3/T2 samples was established in at least 28 days (4 °C), while the QIM threshold (6) was exceeded after 7/21 days in untreated/T1 fillets. CONCLUSION: The fish shelf life was extended with vapour OEO treatment using this new technology, similarly to OEO dipping treatment, according to QIM, corroborated by the microbial quality and TMA‐N contents. © 2020 Society of Chemical Industry

Abstract	Radiation-induced dermatitis is a common complication of radiotherapy. In Spain, the manufactured products used to prevent and treat that condition consist of emollient creams (which are often ineffective) or corticosteroids (which can cause dermal atrophy and other adverse effects). However, we have found that topically applied melatonin, a product that to our knowledge is not commercially available in Spain, is safe and effective in the prevention and treatment of radiodermatitis and a viable substitute for corticosteroid therapy. In this report, we describe the use of compounded melatonin in Beeler cream (the formulation for which is provided) in a 46-year-old woman who underwent surgery and radiotherapy for early stage adenocarcinoma of the breast. The patient applied that cream as directed throughout the prescribed course of radiotherapy and continued its use for 3 weeks after she last underwent irradiation. She experienced no adverse effects from the use of the compounded formulation and tolerated that treatment well. Radiation dermatitis did not develop at the irradiated site until approximately 1 week after the final radiotherapy session, at which time mild erythema of the treated skin emerged. That condition, which was successfully treated by application of the melatonin-containing cream as previously prescribed, resolved after 3 weeks of its use. We suggest that when manufactured products designed to prevent or treat the adverse dermal effects of radiotherapy are unavailable, fail to be effective, or prove objectionable to patients, a melatonin-containing topical compound can provide a successful alternative.

Abstract	The mechanism underlying impaired learning and memory in Alzheimer's disease is not fully elucidated. The phosphorylation of cyclic-AMP response element binding protein (pCREB) in the hippocampus is thought to be a critical initiating step in the formation of long-term memories. Here, we tested CRE-driven gene expression following learning in mice harboring the familial Alzheimer's disease-linked APPswe/PS1ΔE9 mutations using CRE-β galactosidase reporter. We show that young adult APPswe/PS1ΔE9 mice exhibit impaired recognition memory and reduced levels of pCREB, and its cofactors CREB binding protein (CBP) and p-300 following a learning task, compared to their wild type littermate counterparts. Impairments in learning-induced activation of CREB in these mice are manifested by reduced CRE-driven gene transcription. Importantly, expression of the CRE-driven immediate early gene, Egr-1 (Zif268) is decreased in the CA1 region of the hippocampus. These studies implicate defective CREB-dependent plasticity in the mechanism underlying learning and memory deficits in Alzheimer's disease.

Abstract	In recent years, the delta opioid receptor has attracted increasing interest as a target for the treatment of chronic pain and emotional disorders. Due to their therapeutic potential, numerous tools have been developed to study the delta opioid receptor from both a molecular and a functional perspective. This review summarizes the most commonly available tools, with an emphasis on their use and limitations. Here, we describe (1) the cell-based assays used to study the delta opioid receptor. (2) The features of several delta opioid receptor ligands, including peptide and non-peptide drugs. (3) The existing approaches to detect delta opioid receptors in fixed tissue, and debates that surround these techniques. (4) Behavioral assays used to study the in vivo effects of delta opioid receptor agonists; including locomotor stimulation and convulsions that are induced by some ligands, but not others. (5) The characterization of genetically modified mice used specifically to study the delta opioid receptor. Overall, this review aims to provide a guideline for the use of these tools with the final goal of increasing our understanding of delta opioid receptor physiology.

Abstract	The use of vapour of essential oils (EOs) through an innovative pilot-plant packaging device was studied to preserve the quality of sliced mushrooms during storage. A mix of EOs (eugenol, bergamot EO, and grapefruit EO) was vaporized (100 and 125 µL L⁻¹) and applied during packaging of sliced mushrooms under modified atmosphere packaging (MAP); then, the product quality was studied during cold storage up to 12 days. The highest colour changes of EOs125 samples, which were observed in the mushroom stipe, were not observed with the EOs100 atmosphere. Thus, the high polyphenoloxidase activity observed in untreated samples after 5–7 days was highly controlled with the vapour EOs atmospheres. Furthermore, the visual appearance scores of EOs100 samples were still over the limit of usability, while untreated samples were already below this threshold after 5 days of storage. A strong bacteriostatic effect was achieved with vapour EOs, reducing the Pseudomonas spp. (the main microbial genus in cultivated mushrooms) growth by ≈1.7 log CFU g⁻¹, regardless of the EOs dose, after 12 days. The activity of phenyl ammonia lyase was also reduced up to ≈0.4 enzymatic units with the EOs100 treatment. Conclusively, packaging of sliced mushrooms under an atmosphere enriched with 100 µL L⁻¹ EOs vapour highly controlled the quality loss of sliced mushrooms owing to their enzymatic inhibition and high bacteriostatic effect.

Abstract	Ice containing essential oils (EOs) nanoencapsulated in β-cyclodextrins (β-CD) (named as EOs+β-CD ice) was used for stunning/slaughtering by hypothermia in ice slurry, and for ice storage of gilthead seabream. Clove essential oil (CEO) was used at fish stunning/slaughtering, while ice storage of whole fish was performed using a combination of carvacrol, bergamot and grapefruit EOs (CBG). Inclusion complexes CBG+β-CD were characterized, and antimicrobial effect was also evaluated. The kneading method used to form inclusion complexes with CBG showed a good complexation efficiency. Microbial, physical-chemical and sensory analyses were carried out to assess the quality changes of fresh whole seabream during ice storage at 2 °C for 17 days. Results (microbial, chemical and sensorial) indicated that seabream stunning/slaughtering and storage using EOs+β-CD ice (in low doses of 15 mg/kg ice for stunning, and 50 mg/kg ice for ice storage) improved the quality of fresh fish and extended the shelf-life up to 4 days.

Abstract	Different antimicrobial active packaging treatments were studied on the fresh tomato quality after 6 days/8 °C (short transport simulation) followed by 5 days/25 °C (commercialization). Particularly, active cardboard boxes were coated with a water−based acrylic emulsion containing essential oils (EOs) nanoencapsulated within: β−cyclodextrin (βCD), halloysite nanotubes (HNT) or their combination. As controls, boxes were coated with the pure acrylic emulsion (CTRL) or this emulsion including pure HNT. The initial physicochemical, colour and microbial quality of tomatoes were not affected (p > 0.05) by the active packages. Firmness remained unaffected (p > 0.05) after 6 days at 8 °C using the βCD−EOs and control HNT (no EOs) boxes. Furthermore, decay incidence of tomatoes within βCD−EOs boxes was reduced from 9−15% (rest of treatments) to 2% after an abusive storage period (6 days/8 °C+12 days/25 °C). Conclusively, βCD−EOs active boxes highly retained the fresh tomato quality during the studied storage periods being postharvest losses due to decay highly reduced.
