Collectively, these results help elucidate the crucial roles of TLRs in the immune response of housefly and provide a foundation for further understanding of innate immunity of the housefly. Hydroxyapatite (HA) nanoparticles are promising materials for enzyme immobilization, since they provide a high specific surface area for enzyme loading and can also be modified with metal ions (HA-Me2+) to enable interaction with proteins. Valproic acid cell line The adsorption of proteins on HA-Me2+ has been explored for purification purposes, while the use of this material as a support for the immobilization of enzymes remains to be further investigated. Xylanase is an enzyme of considerable industrial interest, being used in the biofuel, pharmaceutical, pulp, and food & beverage sectors, among others. The immobilization of xylanase can enable recovery of the enzyme after biocatalysis, so that it can be reused several times, hence reducing the costs of industrial processes. Here, a systematic study was performed of the immobilization of xylanase on HA nanoparticles modified with metal ions (Cu2+ and Ni2+). A simple, fast, and efficient immobilization protocol was established using statistical experimental design as a tool, generating derivatives by interactions involving complexation of metals of the support with electron donor groups of the enzyme. The affinity towards xylanase was higher for the HA-Cu2+ support, compared to HA and HA-Ni2+. The pH and temperature profiles for the immobilized enzyme activity remained the same as for the soluble enzyme, indicating that the xylanase did not undergo major changes in its conformational state after immobilization. The HA-Cu2+ support was the most effective in reuse assays, retaining up to 80% activity in the second cycle. The results showed that xylanase could be immobilized on HA nanoparticles modified with Cu2+ and Ni2+ metal ions, using a simple and effective method, indicating the promising potential of the system for applications in different industrial processes. Two drugs that pregnant women (with hypothyroidism) may use during pregnancy include Isoxsuprine hydrochloride (ISO) and levothyroxine (LEV); ISO to reduce uterine contractions and LEV for the treatment of hypothyroidism. In the current work, we explored the mechanism of binding affinity between the above drugs and antioxidant enzyme Bovine Liver Catalase (BLC). The experimental results confirmed that both drugs could bind with BLC to form drug-BLC complexes but LEV showed a higher binding affinity toward enzyme. The binding constants of LEV-and ISO-BLC were 0.42 × 105 and 0.13 × 104 M-1 at 310 K, respectively. LEV enhanced the catalase activity but the enzymatic activity of BLC reduced gradually in the presence of ISO. Both drugs were able to induce conformational changes in the BLC structure. The results of the molecular docking investigations confirmed the experimental data and showed that the main binding forces in the LEV-BLC and ISO-BLC systems were hydrogen bond and hydrophobic force. The best binding site of both drugs on BLC is located at a cavity among the wrapping domain, N-Terminal arm, and β-barrel. V.The effect of putrescine on the dynamics, conformation, and kinetics of acid phosphatase investigated via different experimental and theoretical methods. The Stern-Volmer constants (Ksv) for the acid phosphatase- putrescine compound was obtained at different temperatures. Therefore, putrescine quenched the intensity of the enzyme via the static method. Gibbs free energy displayed which binding process was spontaneous. MD simulation, docking method, and thermodynamic parameters revealed the van der Waals forces and hydrogen bonding that had the specific interaction in unfolding the compound. After putrescine binding, the Vmax amounts of acid phosphatase without changed, and the value of kcat/Km increased. The Tm the acid phosphatase-putrescine compound was decreased. Presumably because of more surface hydrophilicity and further H-bond formation underlying the putrescine modification. As confirmed by fluorescence spectra and UV-Visible spectroscopy. Circular dichroism (CD) and UV absorption investigations also demonstrated which binding of putrescine to acid phosphatase led to microenvironmental variations around the protein. Therefore, putrescine cause changes in its structure and function. The results, therefore, showed the effect of putrescine was because of its kosmotropic specifications. Molecular dynamics simulation and Molecular docking results further confirmed the results obtained by CD and spectroscopy experiments. V.Essential oils are natural antimicrobils and have been frequently incorporated into edible films aimed at extending shelf-life of food products. In this study, thymol nanoemulsions co-emulsified by natural emulsifiers (i.e., blend of gelatin and soy lecithin) were prepared and incorporated into gelatin films. The physical and antimicrobial properties of gelatin films were characterized. Thymol nanoemulsions incorporation increased the water vapor permeability and elongation at break of gelatin film, but decreased the moisture content and tensile strength. With nano-scale and uniform particles, the surface of films containing thymol nanoemulsions was smooth and continuous. Due to the hydrophobic property of lecithin and thymol, the water contact angle of gelatin film increased to above 90°. Moreover, sustained release of thymol from gelatin films was also observed, and these films exhibited effective inhibition activities against both Gram-positive and Gram-negative bacteria. Therefore, gelatin films containing thymol nanoemulsions co-emulsified by gelatin and lecithin may have great potentials to be applied as novel and GRAS biodegradable packaging materials to achieve the goal of extending the shelf life of food products. Channel catfish (Ictalurus punctatus) are one of the most important commercial freshwater fish in the world. China has been the major producer and consumer of channel catfish following the rapid development in the past three decades. In the present study, a novel orthologous myostatin gene, IpMSTNa, of channel catfish was identified based on homology cloning and genome locating. Multiple sequence alignments and gene structure analyses showed that the IpMSTNa gene and its deduced protein presented similar architectures to other known vertebrates. Phylogenetic and synteny analyses indicated that IpMSTNa belongs to MSTN1 orthologues. Pro-IpMSTNa protein is a typical disulphide-linked homodimer, with each chain containing an N-terminal pro-domain and a C-terminal unmatured GF domain, while pro-IpMSTNa present some significant differences in secondary structure and three-dimensional substances with pro-IpMSTNb. Relative expression level of the IpMSTNa gene upregulated rapidly and decreased dramatically during the embryonic and larval developmental stages, respectively.
