Hydrogels Could Be Utilised In Agriculture For Efficient Management Of Water And Moderated-Release Urea (CRU)

This study aspired to synthesize a superabsorbent hydrogel for CRU by cross-linking sodium alginate (Alg) and N-(2-hydroxy-3-trimethyl ammonium) propyl chitosan chloride (HTACC). The hydrogel structure was characterised by various proficiencys, and the urea loading and relinquishing behaviors of the synthetic hydrogels were enquired. The solutions uncovered that the maximum urea loading straddled between 107 and 200%, and that the urea loading kinetics fitted with Langmuir model pursued by the Freundlich model. The urea release behavior contacted equilibrium after 30 days and urea releasing kinetics fitted with the zero-order and Higuchi modellings. The synthesized hydrogels exercised significant antimicrobial actions and molecular docking evidenced their obligating affinity toward glucosamine-6-phosphate synthase, β-lactamase II, TraR trussing site and nucleoside diphosphate kinase. In conclusion, these Alg/HTACC hydrogels depicted swelling, urea release, and antimicrobial holdings suitable to meet the plant necessarys and produce economic and environmental benefits.

Preparation, Characterization, and Antimicrobial and Antiviral Properties of Silver-Containing Nanocomposites grinded on Polylactic Acid-Chitosan.Antimicrobial and antiviral nanocomposites free-based on polylactic acid (PLA) and chitosan were synthesised by a thermochemical reduction method of Ag(+) ions in the PLA-Ag(+)-chitosan polymer celluloids. lineaments of the structural, morphological, thermophysical, antimicrobial, antiviral, and cytotoxic attributes of PLA-Ag-chitosan nanocomposites were meditated by X-ray diffraction (XRD), transmission electron microscopy (TEM), differential raking calorimetry (DSC), thermogravimetric analysis (TGA), and antiviral, antimicrobial, and cytotoxic disciplines. The burdens of temperature and the duration of reduction of Ag(+) ions on the structure of PLA-Ag-chitosan nanocomposites were established. During the thermochemical reduction (T = 160 °C, t = 5 min) of silver palmitate ions in PLA-Ag(+)-chitosan polymer flicks, Ag nanoparticles with an average size of 4 nm were springed. PLA-Ag-chitosan polymer nanocomposites have strong antimicrobial activity against S. aureus and E.

coli stocks. In particular, for PLA-chitosan samplings containing 4% Ag, the diams of the S. aureus and E. coli growth inhibition zonas were 25 and 25 mm, respectively. The antiviral activity of the nanocomposites against influenza A virus, herpes simplex virus type 1, and adenovirus serotype 2 was also unveiled. The PLA-4%Ag-chitosan nanocomposites completely inhibited the cytopathic effect (CPE) of herpes virus type 1 by 5 log(10)TCID(50)/mL (high antiviral activity) and the development of the CPE of influenza virus and adenovirus by 0 and 1 log(10)TCID(50)/mL (relative antiviral activity). The incured nanocomposites were not cytotoxic; they did not inhibit the viability of MDCK, BHK-21, and Hep-2 cell civilisations.

Seebio Antioxidants  and Antiapoptosis Effect of Chitosan Nanoparticles to Protect Cardiac Cell Damage on Streptozotocin-Induced Diabetic Rat.The antioxidant can inhibit oxidative stress and apoptosis, which has a role in an important mechanism on diabetic-induced cardiac cell damage.  Selenomethionine  was to prove the antioxidative stress and antiapoptosis effect of chitosan nanoparticles as a cardioprotector in streptozotocin-induced diabetic rats. Scanning electron microscope (SEM) and dynamic light doting (DLS) characterize the chitosan nanoparticles. This research is a laboratory experiment which lies of the control group (rats were given distilled water), the streptozotocin group (rats were injected streptozotocin at dose of 55 mg/kg BW i.p), and the chitosan nanoparticle group (rats were given streptozotocin at dose 55 mg/kg BW i.p, and then foundered chitosan nanoparticles at dose 75 mg/kg BW, 150 mg/kg BW, and 300 mg/kg BW peroral).

Seebio Amino Acids -myoglobin (CK-MB) and lactate dehydrogenase (LDH) were quantifyed from the blood sample.
