Ecotin, a serine peptidase inhibitor (ISP), discovered in Escherichia coli, inhibit a wide range of trypsin-like serine peptidases, protecting microorganisms from the host's immune response. In eukaryotes, ISPs encoding genes were found only in Trypanosomatidae protozoa, including the genus Trypanosoma, which harbors Trypanosoma cruzi, the ethiological agent of Chagas' disease. T. cruzi encodes the ISP2 Trypanosomatidae orthologous, which in Leishmania species present inhibitory activity on mammalian proteases from S1A family suggesting its role in vertebrate-host-parasite interactions. In this study, the structural and biochemical characterization of the recombinant T. cruzi ISP2 (rTcISP2), produced in E. coli was purified in soluble form and analyzed by circular dichroism, fluorescence spectroscopy, native electrophoresis, dynamic light scattering, low X-ray scattering and homology modeling. The obtained data revealed that rTcISP2 was biologically active and forms homodimers in solution. Furthermore, inhibitory activity of rTcISP2 against human neutrophil elastase (HNE) is the highest among ISP2 orthologous from bacteria and trypanosomatids. The role of NE to control T. cruzi parasites through modulation of cellular and humoral innate immune responses in vertebrate hosts, make TcISP2 a key molecular component for parasite infection efficiency, providing a useful basis for investigation of host-parasite interactions and the potential of TcISP2 for biotechnological applications. A novel progesterone-receptor targeted nanohybrid carrier based delivery of hesperidin was investigated in the present work. Casein‑calcium ferrite nanohybrid carrier was synthesized using desolvation followed by ionic-gelation. The citrus peel extracted hesperidin drug (CHD) was encapsulated in the carrier via pH based coacervation, after which the targeting ligand progesterone was conjugated through activate ester procedure. Adaptaquin The carrier formulation was characterized using techniques like XRD, FTIR, SEM, VSM and DLS. The bioactive components in CHD were analyzed using HPLC. Taguchi optimization gave a maximum of 89.54% hesperidin encapsulation in the carrier. Incorporation of superparamagnetic calcium ferrite nanoparticles resulted in improved drug encapsulation and magnetic induced drug delivery. The carrier exhibited a stimuli-responsive drug release behavior, with good stability at physiological pH (7.4) and a higher release under acidic pH (5.4 and 1.2) favoring anticancer applications. The drug release followed Fickian diffusion mechanism as predicted by different kinetic models. Cell viability assay on L929 fibroblast cells verified the biocompatibility of the formulation. The specific recognition and targeted chemotherapy rendered by the progesterone-conjugated carrier enhanced the cytotoxicity of CHD against SKOV-3 ovarian and MDA-MB-231 breast cancer cells, resulting in a significant 30-fold reduction in the (Half-maximal inhibitory concentration) IC50 values. V.Soybean straw cannot be efficiently degraded and utilized by ruminants due to the complex cross-linked structure among cellulose, hemicellulose, and lignin in its cell wall. Xylanase can degrade the xylan component of hemicellulose, destroy the xylan-lignin matrix and, consequently, would theoretically improve the hydrolysis effectiveness of cellulose. Therefore, this study was performed to investigate the effects of recombinant Lentinula edodes xylanase (rLeXyn11A) on fiber structure, hydrolysis, and in vitro ruminal fermentation of soybean straw. Treatment with rLeXyn11A enhanced the hydrolysis of soybean straw with an evident increase in productions of ribose, rhamnose, and xylose. Soybean straw treated by rLeXyn11A had lower hemicellulose content and greater cellulose and lignin contents. The rLeXyn11A could remove xylan, loosen unordered fibrous networks, enhance substrate porosity, and rearrange lignin, consequently increasing the exposure of cellulose and improving the cellulase hydrolysis of soybean straw. Supplemental rLeXyn11A stimulated the dry matter digestion, volatile fatty acids production, and microbial protein synthesis during in vitro ruminal incubation. This paper demonstrated that rLeXyn11A could strengthen the cellulase hydrolysis and in vitro ruminal fermentation of soybean straw by degrading xylan and changing fiber structure, showing its potential for improving the utilization of soybean straw in ruminants. This study was conducted to evaluate applicability of the previously reported native agarose gel electrophoresis to the analysis of various monoclonal and polyclonal antibodies. Experiments were carried to test the electrophoresis system for characterization of different monoclonal antibodies and animal serum, analysis of expressed antibodies in cell culture and evaluation of antibody stability. An attempt to optimize the electrophoretic condition was made by adjusting the electrode buffer concentration, electrophoretic run time and agarose concentration. In this study, nanocellulose was synthesised by acid hydrolysis of cellulose and was coupled with polypyrrole supporting matrix. The synthesised nanocellulose polypyrrole composite (NCPPY) was characterised by FESEM, XRD, FTIR, BET, TGA/DSC and NMR. These analysis showed the conversion of cellulose to nano sized crystalline structure with excellent thermal stability and higher surface area. The effect of different parameters like pH, temperature, contact time, adsorbent dosage and initial concentration of Chromium (Cr(VI)) and Congo Red (CR) were optimised in batch mode. Response Surface Methodology (RSM) has been employed as an optimization tool for the efficient removal of Cr(VI) and CR and the maximum removal efficiency was found to be 80% and 85% respectively. The Langmuir and Freundlich isotherm well fitted the equilibrium data for CR and Cr(VI) respectively. Thermodynamic data showed that the biosorption of Cr(VI) and CR on NCPPY is an endothermic, spontaneous, and entropy-driven process. The adsorption kinetic followed pseudo-second-order for Cr(VI) and intraparticle diffusion for CR. Effect of co-existing ions were checked using several common salts and heavy metals. Results indicated that NCPPY has great potential to remove Cr(VI) and CR binary mixture under simulated conditions.
