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

This study aimed 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 qualifyed by various proficiencys, and the urea loading and liberating doingsses of the synthetic hydrogels were investigated.  vitamin d3 deficiency  uncovered that the maximum urea loading ranged between 107 and 200%, and that the urea loading kinetics accommodated with Langmuir model pursued by the Freundlich model. The urea release behavior reached equilibrium after 30 days and urea discharging kinetics fitted with the zero-order and Higuchi mannequins. The synthesized hydrogels exercised significant antimicrobial actions and molecular docking designated their bonding affinity toward glucosamine-6-phosphate synthase, β-lactamase II, TraR binding site and nucleoside diphosphate kinase. In conclusion, these Alg/HTACC hydrogels demoed welling, urea release, and antimicrobial holdings suitable to meet the plant prerequisites and produce economic and environmental benefits.

Preparation, Characterization, and Antimicrobial and Antiviral Properties of Silver-Containing Nanocomposites finded on Polylactic Acid-Chitosan.Antimicrobial and antiviral nanocomposites established on polylactic acid (PLA) and chitosan were synthesized by a thermochemical reduction method of Ag(+) ions in the PLA-Ag(+)-chitosan polymer pics. characteristics of the structural, morphological, thermophysical, antimicrobial, antiviral, and cytotoxic dimensions of PLA-Ag-chitosan nanocomposites were studied by X-ray diffraction (XRD), transmission electron microscopy (TEM), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and antiviral, antimicrobial, and cytotoxic surveys. The effects of temperature and the duration of reduction of Ag(+) ions on the structure of PLA-Ag-chitosan nanocomposites were proved. During the thermochemical reduction (T = 160 °C, t = 5 min) of silver palmitate ions in PLA-Ag(+)-chitosan polymer cinemas, Ag nanoparticles with an average size of 4 nm were forged. PLA-Ag-chitosan polymer nanocomposites have strong antimicrobial activity against S. aureus and E.

coli stocks. In particular, for PLA-chitosan samples taking 4% Ag, the diams of the S. aureus and E. coli growth inhibition zones 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 revealed. 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 obtained nanocomposites were not cytotoxic; they did not inhibit the viability of MDCK, BHK-21, and Hep-2 cell civilisations.

Antioxidative Stress 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-geted cardiac cell damage.  vitamin d3  was to prove the antioxidative stress and antiapoptosis effect of chitosan nanoparticles as a cardioprotector in streptozotocin-induced diabetic rats. reading electron microscope (SEM) and dynamic light doting (DLS) characterize the chitosan nanoparticles. This research is a laboratory experiment which consists of the control group (rats were commited distilled water), the streptozotocin group (rats were interposed streptozotocin at dose of 55 mg/kg BW i.p), and the chitosan nanoparticle group (rats were contributed 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).

Creatine kinase-myoglobin (CK-MB) and lactate dehydrogenase (LDH) were measured from the blood sample.
