Abstract
Fish gelatin (FG) and octenyl succinic anhydride starch (OSAS) composite films loaded with 1, 2, 3 and 4 wt% bacterial nanocellulose (BNC) and Satureja Khuzestanica Jamzad essential oil (SKEO) were achieved successfully and their physicochemical and release properties were investigated. The results revealed that incorporation of BNC improved the tensile strength which was associated with FE-SEM, FTIR and XRD. Moreover, this study focused on the release modeling of SKEO in 4, 25 and 37 °C from nanocomposite films using different release kinetic and Arrhenius models. Also, analysis of variance-simultaneous component analysis (ASCA) and exploratory data visualization by principal component analysis (PCA) were carried out to investigate the effects of two controlled factors. Consequently, the Peleg model showed the best fitting of experimental data. The activation energies decreased by increasing the BNC concentration. This research demonstrated the nanocomposite film containing SKEO would be a suitable candidate for active food packaging.

Abstract
This study presents a novel packaging film based on whey protein isolate/κ-carrageenan (WC) with red grape pomace anthocyanins (RGA) to investigate its impact on some qualitative attributes of emergency food bars (EFBs) for 6 months at 38°C. Increasing the RGA dose in WC films from 5% (WCA5) to 10% (WCA10) reduced hydrogen bonding between polymers and polymer homogeneity in the matrix according to FTIR and SEM. Tensile strength slightly declined in WCA5 from 7.47 ± 0.26 to 6.97 ± 0.12, while elongation increased from 27.74 ± 1.36 to 32.36 ± 1.25% compared to WC film. The maximum weight loss temperature (TM) increased by incorporating 5 wt% RGA from 182.95°C to 244.36°C, whereas TM declined to 187.19°C in WCA10 film. WVP and OTR slightly changed in WCA5 (from 7.83 ± 0.07 and 2.57 ± 0.18 to 8.41 ± 0.03 g H2O.m/m2.Pa.s × 10-9 and 1.79 ± 0.32 cm3 O2/m2.d.bar, respectively), but significantly impaired in WCA10 compared to WC film. WCA5 and WCA10 films had high AA%, 68.77%, and 79.21%, respectively. WCA10 film presented great antimetrical properties against Staphylococcus aureus with an inhibition zone of 6.00 mm. The light transmission of RGA-contained films in the UV spectrum was below 10%. The WCA5 film effectively restrained moisture loss and hardness increment until the end of the storage period, which were 14.33% and 28.76%, respectively, compared to day 0. Antioxidant films provided acceptable resistance against oxidation to EBF treatment. Sensory panels scored WCA5 and WCA10 higher in overall acceptance with 5.64 and 5.40 values, respectively, while complaining about the hardness of OPP treatment. The results of this investigation demonstrated that incorporating RGA, preferably 5 wt%, into WC-based film effectively improved the qualitative properties of EFB during the 6-month shelf life. This film might be a promising alternative for packaging light and oxygen-sensitive food products.

Abstract
Sodium acid pyrophosphate (SAPP) food additive is widely used as a preservative, bulking agent, chelating agent, emulsifier and pH regulator. It is also used as an improver of color and water retention capacity in the processing of various types of seafood, canned food, cooked meat and flour products. For the first time, we evaluated the SAPP interaction with bovine serum albumin (BSA) using spectroscopic methods including UV-Vis absorption, fluorescence spectroscopy, and surface plasmon resonance, and docking analysis to understand the mechanisms of complex formation and binding. The fluorescence intensity of BSA reduces when titrated with various concentrations of SAPP by forming a complex with BSA via a static quenching mechanism. The binding constant between BSA and SAPP decreased from 123,300 to 15,800 (M-1) with rising temperature, which indicates a decrement in complex formation owing to the interaction of SAPP with BSA. A negative ΔG° value means that SAPP binds spontaneously to BSA at all temperatures, and both ΔH° and ΔS° negative values indicate that hydrogen bonds (H-bonding) and van der Waals forces are the primary forces involved in the binding processes. The UV-Vis spectrum of BSA reduced upon increasing SAPP concentrations due to forming a new ground state complex between SAPP and BSA. Molecular docking study shows that residues Arg256, Ser259, Ser286, Ile 289 and Ala 290 play an important role in SAPP binding process to site I (subdomain IIA) of BSA through H-bonding and van der Waals forces, which is supported by the thermodynamic study.Communicated by Ramaswamy H.

Abstract
Since the world's population has surged in recent decades, the need for sustainable as well as environmentally friendly protein sources is growing. However, there are daunting challenges in utilizing these protein sources in the food industry due to their poor techno-functional properties compared with animal proteins. Numerous procedures have been introduced to improve plant protein functionalities with related pros and cons. Among them, complexation with polysaccharides is considered a safe and effective process for modulating plant proteins' technological and industrial applications. Notwithstanding the nutritional value of soy protein (SP) as a "complete protein," it is a crucial protein commercially because of its rank as the highest-traded plant-based protein worldwide. The current review deals with SP complexation with ionic polysaccharides, including chitosan, alginate, carrageenan, and xanthan gum, and their effects on the physicochemical and techno-functional properties of SP. Accordingly, the structure of SP and the abovementioned polysaccharides have been considered for a better understanding of the possible interactions. Then, the changes in the physicochemical and functional properties of SP and their potential applications in the formulation of plant-based food products have been discussed. Overall, ionic polysaccharides at optimum conditions would improve the functional properties of SP by altering its secondary structure, making it suitable for a wide range of applications in the food industry.

Abstract
Despite the regulatory role of Tau protein in the stabilization and assembly of microtubules, this protein has an important function in the protection and stabilizing of DNA molecules in the cell nucleus. In the present study, it has been indicated that glycation of lysine residues (Lys-267, Lys-274, and Lys-280) in the microtubule-binding domain (MBD) can considerably decrease its binding affinity to DNA molecules. The structural analysis also confirmed that the decreased glycated tau-DNA complex's stability was due to structural modification of this protein after the glycation process. The study of hippocampal cells under hyperglycemic conditions showed that near to 70% of Tau proteins glycated in these cells, although the expression of Tau remained unaffected. The assessment of H3K9me2, as a marker for binding of Tau to pericentromeric heterochromatin (PCH), indicated that localization of Tau protein on PCH was remarkably decreased at high glucose conditions relative to the controls. It is suggested that increasing the structural stability of Tau protein limits the ability of this protein for DNA binding, while the molecular and physical barrier of glycated Lys residues should not be neglected.

Abstract
The new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that was first found in 2019 in Wuhan, China, caused coronavirus disease 2019 (COVID-19). It then spread worldwide rapidly, causing the 2019-2020 coronavirus pandemic. To date, it has been indicated that various transmission ways might be participated in outbreaks of COVID-19. Among these, food products, whether raw or processed, might be carriers for SARS-CoV-2. Therefore, this study was aimed to evaluate the effect of cooking and microwave process of meat products and bread on the stability of SARS-CoV-2. In this regard, sausages and hamburger as meat products and toast bread were inoculated with a viral load of 5.70 log fifty percent tissue culture infective dose (TCID50)/mL in order to create a simulated cross-contamination condition. The results showed that frying of hamburger at 225ºC for about either 6 or 10 min resulted in complete inactivation of SARS-CoV-2. Furthermore, a 5-log decrease in SARS-CoV-2 load was observed in sausages as a consequence of cooking process at 78ºC for either 20 or 30 min. Additionally, the effect of microwave oven at power of 630 watt on stability of SARS-CoV-2 showed that exposing toast bread for either 30 s or 1 min in this power led to a 5-log decrease in SARS-CoV-2 load in the toast bread.

Abstract
Vitamin D (VD) deficiency is a significant issue affecting a large population around the world. As its natural sources are limited, people must constantly fortify their VD. Encapsulating VD increases its bioavailability and stability during processing and storage; hence it has promising potential to avoid VD deficiency. This study reviews current methods of VD fortification and encapsulation. Two predominant methods of VD fortification, i.e., biofortification and direct fortification, are advantageous over VD supplementation. However, significant VD losses occur during processing, storage, and passing across the stomach which can be minimized through encapsulation methods, i.e., micro and nanoencapsulation. Moreover, the capsule features like size, wall-to-core ratio, wall material, carrier oil composition, and encapsulation technique significantly affect VD bioavailability. To assess the optimum encapsulation procedures and possible risks in food fortification, comprehensive in vitro and in vivo studies must be conducted. Depending on the staple food products of a specific region, both VD fortification strategies have great potential in different countries. Besides, the risk of VD overdose due to fortifying a single staple food product is higher than fortifying various staple food products.

Abstract
The present investigation was performed to determine the stability of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) under several industrial processing situations in dairies, including pasteurization, freezing, and storage in acidic conditions. Ten treatments were selected, including high‐temperature short‐time (HTST)‐pasteurized low‐fat milk, low‐temperature long‐time‐pasteurized low‐fat milk, extended shelf life (ESL)‐pasteurized low‐fat milk, HTST‐pasteurized full‐fat milk, LTLT‐pasteurized full‐fat milk, ESL‐pasteurized full‐fat milk, pasteurized cream, ice cream frozen and stored at −20 or −80°C, and Doogh (as a fermented milk drink with initial pH < 3.5) refrigerated for 28 days. The viral particles were quantified by RT‐PCR methodology. Besides, the virus infectivity was assessed through fifty‐percent tissue culture infective dose (TCID50) assay. These products were seeded with a viral load of 5.65 log TCID50/mL as a simulated cross‐contamination condition. Pasteurization techniques were sufficient for complete inactivation of the SARS‐CoV‐2 in the most dairy products, and 1.85 log TCID50/mL virus reduction in full‐fat milk (fat content = 3.22%). Freezing (either −20°C or −80°C) did not result in a virally safe product within 60 days of storage. Storage at high acidic conditions (initial pH < 3.5) completely hampered the viral load at the end of 28 days of refrigerated storage. This research represents an important practical achievement that the routine HTST pasteurization in dairies was inadequate to completely inactivate the viral load in full‐fat milk, probably due to the protective effect of fat content. Furthermore, freezing retain the virus infectivity in food products, and therefore, relevant contaminated foods may act as carriers for SARS‐CoV‐2.

Abstract
The use of liposomes as drug carriers improves the therapeutic efficacy of anticancer drugs, while at the same time reducing side effects. Hyaluronic acid (HA) is recognized by the CD44 receptor, which is overexpressed in many cancer cells. In this study, we developed HA-modified liposomes encapsulating 5-fluorouracil (5-FU) and tested them against a CD44 expressing colorectal cell line (HT29) and a non-CD44 expressing hepatoma cell line. The average size of 5-FU-lipo and 5-FU-lipo-HA nanoparticles were 112 ± 28 and 144 ± 77 nm, respectively. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium (MTT) assay showed selective cancer cell death depending on the CD44 expression in a time-dependent manner. Apoptosis assays and cell-cycle analysis indicated that G0/G1 arrest occurred. The colony formation study revealed that cells treated with 5-FU-lipo and 5-FU-lipo-HA had reduced colony formation. Quantitative reverse-transcription polymerase chain reaction study showed that the oncogenic messenger RNA and microRNA levels were significantly reduced in the 5-FU-lipo-HA-treated group, while tumor suppressors were increased in that group. We suggest that optimal targeted delivery and release of 5-FU into colorectal cancer cells, renders them susceptible to apoptosis, cell-cycle arrest, and decreased colony formation.

Abstract
Epidermal growth factor receptor (EGFR) plays an important role in cell proliferation at non-small cell lung cancer (NSCLC). Therefore, targeted therapy of cancer via this kind of receptor is highly interested. Small molecule drugs such as erlotinib and gefitinib inhibit EGFR tyrosine kinase and thus suppress cell proliferation. At this paper, erlotinib interaction with EGFR on the cell surface was studied via surface plasmon resonance (SPR) and molecular docking methods. Kinetic parameters indicated that erlotinib affinity toward EGFR was increased through increment of temperature. The thermodynamic analysis showed that van der Waals and hydrogen binding forces play a major role in the interaction of erlotinib with EGFR. Docking results showed that Domain II in EGFR has role in the interaction with erlotinib. Besides, the binding energy for this interaction was -10.7 kcal/mol, which is suitable for binding of erlotinib to Domain II in EGFR.

Abstract
Althaea rosea flowers were used to procure the gum (ARG) needed for film preparation. Pretest studies suggested 1.5% ARG + 50% glycerol as optimum for film preparation. The reinforcement impact of 3, 5, and 8 wt% bacterial nanocrystalline cellulose (BNC) incorporation (based on the dry weight of ARG) was investigated on the structural, mechanical, physical, thermal, optical, morphological, and barrier properties of films. The Results suggested that increasing the BNC concentration until a certain level (5 wt% BNC) could improve the latter properties. However, at higher concentration (8 wt% BNC), cellulose nanoparticles tended to agglomerate, which led to the impairment of some of those properties, especially barrier properties. According to AFM and SEM results, BNC addition increased surface roughness and coarseness. All BNC-loaded films showed better functions compared to control sample (0 wt% BNC) and the film containing 5 wt% BNC was suggested as the optimum film.

Abstract
Although it has been widely considered that all-trans retinoic acid (ATRA) is an efficient therapeutic agent for acute promyelocytic leukemia (APL), there is an urgent need for extending and examining new therapeutics in medicine. Dithiocarbamates (DTCs) are one of the recent important chemical synthetic compounds used in cancer therapy. The aim of this study was to evaluate the apoptosis-inducing effect of 2-nitro-1-phenylethylpiperidine-1-carbodithioate (2-NDC) as an active derivative from DTCs, in combination with ATRA on human APL NB4 cells. The viability of treated NB4 cells was measured by 3-(4,5-dimethyltiazol-2-yl)-2,5-diphenyltetrazolium bromide assay in various concentrations (10-120 µM). The proapoptotic effects of 2-NDC were investigated by acridine orange/ethidium bromide staining, DNA ladder formation, and flow cytometry. We also assessed the oxidative stress-inducing effect of 2-NDC and in combination with ATRA on the NB4 cells. The alteration in gene expression levels of Bax, Bcl2, and Survivin was measured through a real-time polymerase chain reaction. Furthermore, we redetected the interaction between 2-NDC and antiapoptotic proteins Bcl2 and Survivin via molecular docking. We found that 2-NDC induced apoptosis in NB4 cells in a time-dosage-dependent manner. Also, 2-NDC triggered apoptosis by expanding intracellular reactive oxygen species, combined with ATRA. Bax/Bcl2 ratio was modulated and Survivin was downregulated in NB4 cells upon 2-NDC treatment. Molecular docking studies indicated that 2-NDC binds to the baculovirus inhibitor of apoptosis protein repeat domain of Survivin and Bcl homology 3 domain of Bcl2 with various affinities. Based on the present observations, it seems that this derivative can be estimated as an appropriate candidate for future pharmaceutical evaluations.

Abstract
Acetylcholine is a fast-acting neurotransmitter in synapses and neuromuscular junctions that is decreased in Alzheimer's disease (AD) by hyper‑activation of acetylcholinesterase (AChE), which leads to progressive loss of memory and neurobehavioral abnormalities. Therefore, AChE inhibitors have therapeutic potential in AD that could include natural compounds such as bile acids. Bile acids, as potent molecules, could improve some types of neurodegenerative diseases via antioxidant effects and other unknown mechanisms. The aim of this study was to investigate beneficial effects of bile acids on AChE catalytic and non‑catalytic functions, amyloid plaque deposit and memory in a rat model of AD. The effects of sodium deoxycholate and cholic acid on AChE activity were assessed by in vitro assay. Then, the bile acids' potential therapeutic effects were investigated on nucleus basalis of Meynert lesioned rats using behavioral evaluation, biochemical tests and histological methods. Molecular docking simulation was also implemented to investigate the possible interaction between bile acids and AChE. According to the in vitro and in vivo results, sodium deoxycholate could efficiently inhibit the catalytic function of the enzyme by interacting with the catalytic site, while cholic acid interacted with the peripheral anionic site and inhibited chaperone activity of the enzyme that led to the reduced amyloid plaque deposition. The co‑administration of cholic acid and sodium deoxycholate showed these compounds are able to simultaneously inhibit the catalytic and non‑catalytic functions of the enzyme. This study clarifies the roles of natural bile acids in the nervous system and in AChE function through multiple experimental and simulation methods.

Abstract
Stilbene derivatives have been found to possess promising anticancer activities against human cancer cell lines in vitro. In the present study, we have investigated cytotoxic, apoptosis induction and DNA binding activity of new stilbene derivative, (E)-1-(4-Chlorophenyl)-4,5-diphenyl-2-[4-(4-methoxystryl)phenyl]-1H-imidazol (STIM) on K562 chronic myeloid leukemia cell line. Via MTT assay STIM demonstrated cytotoxic activity against K562 cell line with IC50 value of 150 µM. Apoptosis, as the mechanism of cell death, was evaluated by morphological study and flow cytometric analysis. In vitro DNA binding property of STIM has been studied by vital spectroscopic techniques, which indicated that STIM interact with ctDNA through groove binding mode and binding constant (Kb) was estimated to be 6.9 × 104 M-1. Docking studies revealed that hydrophobic is the most important interaction in STIM-DNA complex, and that the ligand (STIM) interacts with DNA via groove binding mode and the bindiyspng energy was calculated as -13.37 kcal/mol. Taken together, the present study suggests that STIM exhibits anticancer effect on K562 cell line through the induction of apoptosis as well as cell cycle arrest at Sub-G1 phase and also can bind to double helix DNA in vitro.

Abstract
Water molecules play a vital role in efficient drug binding to its target. Thiazolidinediones (TZDs), a class of anti-diabetic drugs, are widely used for treatment of type 2 diabetes mellitus. In the present study, the possible contribution of water molecules to the binding of TZDs to catalase, a potential target in the liver, was investigated by different experimental and theoretical methods. These studies indicated that TZDs could significantly improve the catalase catalytic function with a significant contribution from water molecules. As a probe for the differential number of released water molecules during the catalase transition from E to E* states, the activity of TZDs-catalase complexes was demonstrated to be mainly dependent on water activity. However, free catalase decomposed the substrate more independently. In addition, the spectrofluorimetry studies showed that the binding of TZDs to catalase needed the release of water molecules from the enzyme's binding pocket. The thermodynamic studies indicated that the binding enthalpy and entropy of TZDs for catalase were decreased with lower water activity. The favorable process contributes to release of water molecules from the binding pocket through the formation of hydrophobic interactions between catalase and TZDs in an enthalpic manner. Molecular docking simulations confirmed that the depletion of water molecules from the binding cavity is essential for effective interactions between TZDs and catalase.

Abstract
Purpose Phenytoin is a major anticonvulsant drug that is effective to improve arrhythmia and neuropathic pain. According to early works, phenytoin affected cell membrane depolarization by sodium channel blocking, guanylyl and adenylyl cyclase suppression that cause to intracellular Na+ and Ca2+ downregulation. This study was aimed to clarify some ambiguities in pathophysiological action of phenytoin by in vitro and molecular docking analyses. Methods In this study intracellular free Ca2+ of primary culture of embryonic mouse hippocampus evaluated via Fura 2 as fluorescent probe. The effects of phenytoin on ADP ribosyl cyclase activity was assessed by recently developed fluorometric assay. Molecular docking simulation was also implemented to investigate the possible interaction between phenytoin and CD38. Results Our results confirmed phenytoin competitively inhibits cyclase activity of CD38 (IC50 = 8.1 μM) and reduces cADPR content. cADPR is a Ca2+-mobilising second messenger which binds to L-type calcium channel and ryanodine receptors in cell and ER membrane and increases cytosolic free Ca2+. Ca2+ content of cells decreased significantly in the presence of phenytoin in a dose dependent manner (IC50 = 12.74 µM). Based on molecular docking analysis, phenytoin binds to deeper site of CD38 active site, mainly via hydrophobic interactions and consequently inhibits proper contact of substrate with catalytic residues specially Glu 226, Trp 186, Thr221. Conclusion Taken together, one of the anticonvulsant mechanisms of phenytoin is Ca2+ inhibition from CD38 pathway, therefore could be used in disorders that accompanied by CD38 over production or activation such as heart disease, depression, brain sepsis, airway disease, oxidative stress and inflammation. ᅟ ![]()

Abstract
Drug delivery systems for cancer chemotherapy are employed to improve the effectiveness and decrease the side-effects of highly toxic drugs. Most chemotherapy agents have indiscriminate cytotoxicity that affects normal, as well as cancer cells. To overcome these problems, new more efficient nanosystems for drug delivery are increasingly being investigated. Polyamidoamine (PAMAM) dendrimers are an example of a versatile and reproducible type of nanocarrier that can be loaded with drugs, and modified by attaching target-specific ligands that recognize receptors that are over-expressed on cancer cells. PAMAM dendrimers with a high density of cationic charges display electrostatic interactions with nucleic acids (DNA, siRNA, miRNA, etc.), creating dendriplexes that can preserve the nucleic acids from degradation. Dendrimers are prepared by conducting several successive "generations" of synthetic reactions so their size can be easily controlled and they have good uniformity. Dendrimers are particularly well-suited to co-delivery applications (simultaneous delivery of drugs and/or genes). In the current review, we discuss dendrimer-based targeted delivery of drugs/genes and co-delivery systems mainly for cancer therapy.

Abstract
Purpose: The study on the interaction between various compounds and macromolecules such as enzymes has been very important for monitoring the alteration of structural and functional properties of them. Resveratrol (3, 5, 4-trihydroxy-stilbene; RES) is a biologically active phytoallexin found in grapes and other food products. This article shows an interaction of native bovine liver catalase (BLC) with natural antioxidant product, trans resveratrol (tRES) using multispectroscopic methods. Methods: The interaction between BLC and tRES is performed using UV-vis absorption, fluorescence and circular dichroism (CD) spectroscopy and molecular docking study. Results: In vitro kinetic studies indicated that tRES can decrease BLC activity through uncompetitive inhibition. The results of spectroscopic methods represented that the binding of tRES with BLC can change the micro-region around aromatic amino acids (tryptophan (Trp) and tyrosine (Tyr)) and quench intrinsic fluorescence of BLC by a static mechanism. According to fluorescence quenching data analysis, it was revealed that tRES has one binding site on BLC. The thermodynamic parameters were obtained, which demonstrated that tRES can bind to BLC by van der Waals forces and hydrogen bonds. Molecular docking results indicated that tRES binds to BLC away from heme group and near to the Tyr 324 and Phe 265. These results are in agreement with the experimental results. Conclusion: The inhibitory effect of tRES on BLC demonstrated that excessive consumption of the antioxidants could be resulted in hazardous effects.

Abstract
Introduction: The study on the side effects of various drugs and compounds on enzymes is a main issue for monitoring the conformational and functional changes of them. Quercetin (3,5,7,3',4'-pentahydroxyflavone, QUE), a polyphenolic flavonoid, widely found in fruits, vegetables and it is used as an ingredient in foods and beverages. The interaction of bovine liver catalase (BLC) with QUE has been studied in this research by using different spectroscopic methods. Methods: In this work, the interaction of QUE with BLC was investigated using different spectroscopic methods including ultraviolet-visible (UV-vis) absorption, circular dichroism (CD) and fluorescence spectroscopy and molecular docking studies. Results: Fluorescence data at different temperatures, synchronous fluorescence and CD studies revealed conformational changes in the BLC structure in the presence of different concentration of QUE. Also, the fluorescence quenching data showed that QUE can form a non-fluorescent complex with BLC and quench its intrinsic emission by a static process. The binding constant (Ka) for the interaction was 104, and the number of binding site was obtained ~1. The ∆H, ∆S and ∆G changes were obtained, indicating that hydrophobic interactions play a main role in the complex formation. In vitro kinetic studies revealed that QUE can inhibit BLC activity through non-competitive manner. Molecular docking study results were in good agreement with experimental data, confirming only one binding site on BLC for QUE at a cavity among the wrapping domain, threating arm and β-barrel. Conclusion: Inhibition of BLC activity upon interaction with QUE demonstrated that in addition to their beneficial effects, they should not be overlooked for their side effects.
