    Abstract In line with the application of green techniques in the recovery of bioactive compounds, this research study aimed to evaluate the efficiency of supercritical Co₂ and water distillation in the extraction of sweet basil essential oil. In addition, the effect of wall material made of native gums as well as Lepidium sativum (LS), Lepidium perfoliatum (LP), and a combination of both (LP/LS), following freeze-drying method, on Nano-emulsion properties of encapsulated sweet basil essential oil was evaluated. The encapsulation efficiency (EE%), particle size, polydispersity index, zeta potential (ζ), scanning electron microscopy, viscosity, Brix, pH, density, humidity, water activity, and Fourier transform infrared of nano encapsulated powder were studied. The EE of supercritical fluid was significantly higher (6.3%) in contrast to the distillation of water (1.4%). To study the oxidative stability, essential oil of sweet basil in free mode 1%, 5% and 20% (w/w) and in the encapsulated form 20% (w/w) added to Kilka oil and compared with tert-butylhydroquinone (TBHQ) as synthetic antioxidants at 0.01% (w/w). The results showed that sweet basil essential oil had antioxidant activity and reduced the oxidation process. Unlike free essential oil, nanocapsule essential oil (especially with a coating of LP gum) showed better antioxidant activity comparable to that of TBHQ. Thus, encapsulated sweet basil essential oil with LP gum showed promising results in retarding the fish oil oxidation, which can be introduced as a novel natural antioxidant specifically in emulsion, based food systems.

    Abstract This study aimed to apply H₂O₂ at different concentrations in combination with mince:water (M:W) ratios and different washing cycles (WCs) to produce surimi gel from silver carp without compromising its quality characteristics. Color, texture, microstructure, and rheological properties of surimi gels were investigated. Water holding capacity, texture profile, and gel strength showed a greater dependency on number of WCs than the M:W ratios and percentage of H₂O₂ (p < .05), that is, higher WCs, firmer surimi gel. Accordingly, T2 (one WC, 2% H₂O₂, 1:3), T10 (two WC, 1% H₂O₂, 1:2), and T16 (three WC, 1% H₂O₂, 1:2) treatments resulted the most cohesive and resilient surimi compared with the rest (p < .05), confirmed by scanning electron microscopy images. However, all treated fish mince samples with H₂O₂, resulted in a surimi gel with lower texture quality compared with the control surimi prepared by conventional washing process without H₂O₂ (p < .05). A temperature sweep test was conducted based on the linear viscoelastic region stress and frequency values and the aforementioned surimi gels exhibited an obvious valley shape pattern at temperature range of 48–62°C. In the creep–recovery test, the Burgers model satisfactorily described the internal structure of the surimi gel samples as the lowest deformation belonged to the control samples followed by T2. However, after 300 s strain, neither of surimi gels were fully recovered their original shape. Altogether, further studies are needed to clarify the effects of H₂O₂ in reduction of WCs, without significantly affecting the textural and rheological properties of resultant surimi gel.

    Abstract Breast cancer is the second cause of death in the world. Ionising radiation is a potent mutagen that can cause DNA damage, chromosomes breakage, and cell death. In the present study, radiotherapy and nanoparticle-antibodies (ABs) have been combined to enhance the efficacy of cancer cell treatment. Silver nanoparticles (SNP) were synthesised, coated with anti-HER2, and then characterised with different techniques such as X-ray diffraction, dynamic light scattering, transmission electron microscopy, Fourier transform infrared, and UV-Vis spectroscopy. SKBR3 cells were irradiated with cobalt-60 in the presence of nanoparticle-AB as the drug. Cell viability was measured using the diphenyltetrazolium bromide assay, and the cellular status was assessed by Raman spectroscopy. Irradiation considerably decreased cell viability proportionate to the dose increase and post-irradiation time. The surface-enhanced Raman spectroscopy increased the signal in the presence of SNP. Increasing the dose to 2 Gy increased the irradiation resistance, and higher dose increases (4 and 6 Gy) enhanced the irradiation sensitivity. Moreover, the cellular changes induced by irradiation in the presence of the drug were stable after 48 h. The authors results introduced the combination of the drug with radiation as an effective treatment for cancer and Raman spectroscopy as a suitable tool to diagnose effective irradiation doses.

    Abstract Increased levels of iron in body are attributed to higher cancer risk. Given the fact that 16% of all human cancers are caused by viral infections, iron is suggested to play an important role in carcinogenesis particularly those induced by viral infections. The present study provides an updated summary of the literature and the plausible mechanisms of iron involvement in cancer development by viruses. Our understanding about the interplay between viral infections and iron in different settings particularly cancer development is yet to be improved as it may shed a new light in development of new therapeutic strategies.

    Abstract Background and objectives: Host genetic changes like single nucleotide polymorphisms (SNPs) are one of the main factors influencing susceptibility to viral infectious diseases. This study aimed to investigate the association between the host SNP of Toll-Like Receptor3 (TLR3) and Toll-Like Receptor7 (TLR7) genes involved in the immune system and susceptibility to COVID-19 in a sample of the Iranian population.
    Materials and methods: This retrospective case-control study evaluated 244 hospitalized COVID-19 patients as the case group and 156 suspected COVID-19 patients with mild signs as the control group. The genomic DNA of patients was genotyped for TLR7 (rs179008 and rs179009) and TLR3 (rs3775291 and rs3775296) SNPs using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
    Results: A significant association between rs179008 SNP in the TLR7 gene and the susceptibility of COVID-19 was found between case and control groups. The AT genotype (Heterozygous) of TLR7 rs179008 A>T polymorphism showed a significant association with a 2.261-fold increased odds of COVID-19 (P=0.003; adjusted OR: 2.261; 99% CI: 1.117-4.575). In addition, a significant association between TC genotype of TLR7 rs179009 T>C polymorphism and increased odds of COVID-19 (P<0.0001; adjusted OR: 6.818; 99% CI: 3.149-14.134) were determined. The polymorphism frequency of TLR3 rs3775291 and rs3775296 genotypes were not significantly different between the case and control groups (P> 0.004167).
    Conclusion: SNPs in TLR7 rs179008 and rs179009 genotypes are considered host genetic factors that could be influenced individual susceptibility to COVID-19. The SNPs in TLR3 (rs3775296 and rs3775291) showed no significant association with COVID-19 in Iranian population.

    Abstract The present study was conducted to evaluate the effect of adding marjoram and zataria essential oils (MEO and ZEO) on common carp surimi during frozen storage at −18°C. Surimi was divided into three groups. To one group, no essential oil (EO) was added (Control), and two others were supplemented with MEO and ZEO at a level of 0.5% (w/w). All treatments were analyzed after 1, 3, and 6 months. The texture profile was altered by addition of EOs. Provision of MEO and ZEO reduced peroxide value (PV) to 3.91 meq/kg and 4.06 meq/kg, respectively, compared to control (4.69 meq/kg). Both thiobarbituric acid (TBA) and total volatile basic nitrogen (TVB-N) contents were lower for surimi supplemented with EOs. Total psychrotrophic and pseudomonas bacteria were lower in EOs treated surimi. Addition of EOs were effective in reducing oxidation and preventing microbial growth during frozen storage; however, ZEO was more effective than MEO.

    Abstract Sunflower protein isolate obtained from industrially de-oiled press cake was treated with non-thermal microwave, aiming to investigate how structure and emulsifying properties were affected. Our results indicated that the content of polar amino acids was decreased and solubility and surface hydrophobicity were altered upon exposure to non-thermal microwave. Higher solubility and surface hydrophobicity of the samples treated with defrost mode and also 350 W were accompanied by a smaller size and lower uniformity of the oil droplets compared to the control and other samples. Non-thermal microwave treatment improved the emulsion stability by 1.43 times and defrost mode treated sample had the lowest stability index after 120 min. Interfacial dilatational rheology measurements revealed that 70 and 350 W treated samples created higher elastic, less stretchable solid-like layer at the O/W interface in comparison with defrost mode treated and control samples. Consequently, non-thermal microwave treatment could be considered as a promising simple, fast, and “green” protein modification technique.

    Abstract Collagen and collagen hydrolysate (CH) was recovered from the bone and skin containing sediment residue emerging during pH-shift-based protein isolation from silver carp. Hydrolysis resulted in higher yield (15.1-15.4%) compared to collagen isolation by acid or pepsin (3.1-5.9%) (p<0.05). Isolated collagens were characterized as type I and maintained their triple-helical structure, confirmed by SDS-PAGE and FTIR. Pepsin-hydrolysis and sequential hydrolysis by pepsin and trypsin hydrolyzed all heavy molecular weight chains of collagen but sequential hydrolysis yielded higher degree of hydrolysis. When CH was added to a silver carp protein isolate prior to gelation, the gel behavior was dependent on molecular weight of the added CH. More hydrolyzed collagen emerging from sequential hydrolysis improved water holding capacity of the gel while reducing its breaking force. Thus, residue from pH-shift processing of fish can be used for isolation of high quality collagen/CH and provides a promising basis for a multiple-product fish biorefinery.
