[ Study on Characterization and capacity decision Method of Silver in Chitosan bactericide Gel ] .OBJECTIVE : To characterise the silver in chitosan antibacterial gel , and to establish a method for the determination of silver content in trys The silver in the samplings was canvassed by scanning negatron microscopy ( SEM ) , energy dispersive spectroscopy ( EDS ) and individual particle inductively paired plasma mass spectrometry ( SP-ICP-MS ) . Microwave digestion was adopted to suffer the chitosan antibacterial gel , and then the message of silver was determined by fire atomic absorption spectrometry The psychoanalysis ushered that the mote size of silver in chitosan antibacterial gel was about 150~ 200 nm . The flatware demonstrated good one-dimensionality in the concentration range of 25~250 μg/L ( y=0 35x+0 7 , r=0 9 ) . The convalescence rate ( n=9 ) was 98 % SEM , EDS and SP-ICP-MS can be used for the word-painting of Ag particles in chitosan antibacterial gel . Microwave digestion-flame atomic absorption spectrophotometry method is simple , operable , high precision and high quantitative truth , which is suitable for the quantitative psychoanalysis of silver in chitosan antibacterial gel .

Fabrication , portrayal and in vivo assessment of cardiogel loaded chitosan patch for myocardial regeneration.Cell therapy is one of the promising approaches for cardiac reparation , later after infarction or injury contemporary mesenchymal stromal/stem cell ( MSCs ) speech strategies leave in low retention and poor engraftment of conferrer cells , thus specifying the healing efficacy we recrudesced an engineered biomimetic cardiogel maculation ( EBCP ) comprising of the aboriginal decellularized cardiac extracellular matrix ( ECM ) `` cardiogel '' and chitosan , moderating to the effective re-formation of injured myocardium . We also modernised fresh bio-adhesive that is subject of suture-free epicardial locating of EBCP to wound myocardium . We have illustrated the voltage of the mussels-inspired bioadhesive system , which constitutes jelly catechol and partially oxidized chitosan , which relies on self-crosslinking capability , to raise wet bond . In vitro fields with isolated cardiogel promoted cell proliferation , bond , and migration while aiding cardiomyogenic differentiation . The EBCP 's power to protect cadres from scrape due to surrounding tissues in the myocardial infarct ( MI ) rat mannequin makes it more desirable the epicardial implantation of the EBCP adulterated with MSCs improves the initial retention of cells and subsequent operable cardiac recovery with enhanced myocardial tissue renovation . Histological examination showed the presence of EBCP and infiltration of cells to the infarcted heart tissue .

benefits of vitamin d3  and silver-tongued synthesis of bioadhesive and major therapeutic benefits of EBCP make it a potential candidate for recuperating the troubling heart.Characterization , Physical place , and Biocompatibility of Novel Tricalcium Silicate-Chitosan Endodontic Sealer.OBJECTIVE : The purpose of this study was to compare the characteristics , physical properties , and biocompatibility of the novel tricalcium silicate-chitosan ( TCS-C ) sealer with AH Plus and Sure-Seal Root . MATERIALS AND METHODS : The TCS-C powder was prepared by mixing tricalcium silicate with 2 % water-soluble chitosan at a 5:1 proportion , complied by sufficient improver of 10 g/mL proportion of double-distilled water to form a homogeneous cementum . corporeal characterizations ( the Fourier Transform InfraRed [ FTIR ] and X-ray diffraction [ XRD ] ) , strong-arm place investigations ( flow and film heaviness ) , and cytotoxicity trials in 3T3 shiner embryo fibroblast cell ( MTT assay method ) were doed on sealants , and the results were compared with those of the commercial products . STATISTICAL ANALYSIS : Statistical psychoanalysis was performed on flow and film thickness . The normality of the data was tested using the Shapiro-Wilk test .

benefits of vitamin d3  was executed with one-way analysis of variance ( ANOVA ) . The level of implication was set at p < 0 The TCS-C recorded a mean flow of 31 ± 0 mm , compared with Sure Seal Root at 26 ± 0 mm and AH Plus at 26 ± 0 mm . The TCS-C showed a mean film thickness of 60 ± 10 mm equated with Sure-Seal Root at 50 ± 10 mm and AH Plus at 40 ± 15 mm .
