Notes

A unique elateroid lineage coming from mid-Cretaceous Burmese silpada (Coleoptera: Elateroidea).
Application of this sulphated polysaccharide as a carrier for drug delivery with rutin as a model drug was explored. The drug release kinetics was modeled and the stability of the rutin encapsulated SP nano formulation was studied. Phenoloxidase (PO) is a crucial enzyme in the Arthropods melanization process, in which synthesized melanin rapidly acts at the site of injury and infection. In this study, we observed significant changes in humoral and cellular responses after exposing susceptible and resistant strains to a sub-lethal concentration of Cry1Ah toxin. Based on STRING v 11.0 computational protein-protein interaction analysis, we selected seven immune genes namely Prophenoloxidase PPO1b, PP03, Serpin-3, Serpin-5, Beta-1,3-glucan recognition protein, Immulectin-3 and Serine protease SP105 reported in Asian corn borer. Quantitative real-time PCR gene expression studies showed Cry1Ah resistant strain had higher expression of PPO1b, PP03, Serpin-3, Beta-1,3-glucan recognition protein, Immulectin-3 and Serine protease SP105 genes in midgut and hemocyte samples. This study also investigated and found that the level of prophenoloxidation (proPO) activity in Cry1Ah resistant strains was significantly higher than susceptible strains. Cry1Ah toxin significantly increased the resistant strain's immune responses, the difference was observed through assays of bacterial agglutination and phagocytosis. Additionally, immune response induced by Cry1Ah toxin influences the microbiome composition associated with the host system. These parameters seem to explain the contribution of PO/PO regulating proteins render the host to resist the Cry1Ah toxin. This study describes the development of a novel biocompatible nanogel/hydrogel nanocomposite system for long-term delivery of bioactive molecules. To this aim, the nanogels were synthesized via radical polymerization of poly(N-isopropylacrylamide). The nanogels were introduced during the formation of a hydrogel network to produce nanogel/hydrogel soft nanocomposites, while the biocompatible hydrogel was based on poly (acrylic acid) grafted onto κ-carrageenan polysaccharide with entrapped magnetic iron oxide nanoparticles as crosslinker. In these systems, by using stimuli-responsive functional polymers in both gels (nanogels and hydrogels), pH, thermal and magnetic-responsive properties can be brought to final soft nanocomposites. The obtained soft nanocomposite was characterized by Fourier transform infrared spectrum (FT-IR), thermogravimetric (TG) analysis, and scanning electron microscopy (SEM). This biopolymer based nanogel/hydrogel used as a prolonged releasing drug carrier for levodopa (L-DOPA) as a main drug for treating Parkinson's symptoms. The in vitro release of L-DOPA was investigated at different pHs. pH-dependent release of the active drug can be sustained for >11 days from this soft nanocomposite. The results demonstrated a sustained release model that can be extended for other drugs. V.Magnetic alginate/rice husk (m-ALG/RH) bio-composite beads prepared with ionotropic gelation method and used for methylene blue (MB) removal. Structural analysis of magnetic alginate/rice husk composite beads was performed using FTIR, SEM-EDS and TGA techniques. The accomplishment of magnetic alginate/rice husk composite beads as an adsorbent for the removal methylene blue was investigated from aqueous solution. Maximum experimental adsorption capacity of the bio-composite beads was calculated as 274.9 mg/g. The various process parameters such as pH, temperature and initial MB concentration optimized. It was determined that pH no significant effect on dye removal efficiency of beads while temperature and ionic strength caused a decrease on removal efficiency. The various isotherm models were applied for determine the adsorption mechanism and Freundlich isotherm model is more compatible with the experimental data. The kinetic studies showed that the adsorption of methylene blue can be well described by the fractal Brouers-Sotolongo kinetic model. see more The thermodynamic calculations indicated that methylene blue adsorption was a spontaneous and exothermic nature. The results showed that the magnetic alginate/rice husk bio-composite as low-cost and eco-friendly adsorbent can be effectively used for cationic dye removal steps in the environmental engineering applications. The objective of this work is to research impacts of oxidized (OCS), acetylated (ACS) and cross-linked (CLCS) corn starch on gelatinization properties of rice flour and their gel structure during storage at 4 °C for 1 and 7 days. OCS led to significant increase of pasting temperature and solubility in blend flour but decrease of pasting viscosity and swelling power compared with rice flour, while ACS showed an opposite effect in pasting temperature and viscosity. CLCS remarkably raised pasting temperature and viscosity of blend flour and insignificant increase as increasing concentration, and the mixture showed relatively lower swelling power and solubility than rice flour. During cold storage, OCS and ACS substantially inhibited the reorganization of gel network structure and showed high stability in rheology and texture properties. CLCS accelerated the formation of gel network structure, and the mixture gel appeared to stronger rigid structure and denser microstructure than those of rice gel. Formation distinctions among these three gels were found in rheology properties, texture properties, water migration, FTIR spectra, and microstructure of SEM. Overall, CLCS improved the rice stability in heat-processing, and OCS and ACS reduced the change of rice gel quality during cold storage. Acute lung injury (ALI) is a pulmonary illness with high rates of mortality and morbidity. Rho GTPase and its downstream effector, Rho kinase (ROCK), have been demonstrated to be involved in cell adhesion, motility, and contraction which can play a role in ALI. The electronic databases of Google Scholar, Scopus, PubMed, and Web of Science were searched to obtain relevant studies regarding the role of the Rho/ROCK signaling pathway in the pathophysiology of ALI and the effects of specific Rho kinase inhibitors in prevention and treatment of ALI. Upregulation of the RhoA/ROCK signaling pathway causes an increase of inflammation, immune cell migration, apoptosis, coagulation, contraction, and cell adhesion in pulmonary endothelial cells. These effects are involved in endothelium barrier dysfunction and edema, hallmarks of ALI. These effects were significantly reversed by Rho kinase inhibitors. Rho kinase inhibition offers a promising approach in ALI [ARDS] treatment.
