    Ne, F, and O-like Rydberg resonance lines along with some of the inner shell satellite lines of Copper plasma, in the wavelength range of 7.9-9.5 Å, are experimentally observed using a thallium acid phthalate crystal spectrometer. The plasma is produced by the irradiation of a Cu target with a 15 J, 500 ps Nd: Glass laser with a focusable intensity up to 5 × 10 14 W/cm 2 . The observed lines result from the transitions among 2p-nd, 2p-ns, and 2s-nd (n = 4-6) levels. Transition wavelengths, transition probabilities, and oscillator strengths of these lines are calculated using the Multi-Configuration Dirac-Fock method. In this computation, the contribution of relativistic corrections such as two-body Breit corrections and QED corrections due to vacuum polarization and self-energy has also been considered. FLYCHK simulations are used to analyze the distribution of the various charge states of the Copper ions and to find the temperature and density of plasma. Moreover, the effect of self-absorption of the plasma (opacity), as well as of suprathermal electrons on charge state distribution of ions, is also studied. The synthetic spectrum provides a best-match with the experimental spectrum at a laser intensity of 1.3 × 10 14 W/cm 2 for T c = 150 eV, T h = 1000 eV, f = 0.008, and density 4.5 × 10 20 cm −3 .The temperature and density ranges are also calculated using a radiative hydrodynamic code. The calculated temperature and density range are in agreement with the experimentally determined values. The effect of the change in laser intensity on the L-shell spectrum of Cu is studied which indicates the switching between lower (Cu XX) and higher charge states (Cu XXI and Cu XXII) at higher laser intensities

    Fresh water bodies in populated plains of tropical countries face various disturbances in the form of pollutant and nutrient inflow, heavy metal and elemental precipitation (wet or dry) and constant silt inflow (natural or anthropogenic). The physico-chemical characteristics are very much important for any water body. In lentic water bodies these characteristics shows very much variation because in summer they have less and in rains large amount of water. These adverse constrain effectively influence the algal assemblage and can be a good indicator of overall health of the water body. In the study different Physico-chemical characteristics and algal diversity were monthly observed for one year duration (Jun. 2008 to May 2009).

    Objective: In this study, biodegradable Chitosan Ascorbate Microsphere (CAMs) and mannosylated chitosan ascorbate microsphere (m-CAMs) prepared for targeting towards alveolar macrophages to treatment of pulmonary tuberculosis.  Significance: Ascorbic acid is an antioxidant and reported killing effect on mycobacterium by induces fenton reaction. This study enlightens the possible benefits of adding antioxidant properties of ascorbic acid with chitosan microsphere to an anti-tuberculosis regimen and mannosylation of microsphere significantly induce the targetability of antitubercular drug to alveolar macrophages. Methods: CAMs prepared by firstly salification of chitosan by ascorbic acid then ionic gelation with STPP and m-CAMs prepared by incubation method and purified for further studies. The physicochemical, in vitro and in vivo characterizations of both formulations were carried out. Results: The size of microspheres (both CAMs and m-CAMs) were found to be in range of 3.40-4.81µm. Evident changes were observed in crystallinity and structure of both carrier systems and depicted by Fourier transform infrared (FTIR), Differential scanning calorimetry (DSC) and X-ray diffraction (XRD) studies. In vitro lung deposition study of microspheres showed favourable aerodynamic properties for deep lung delivery (MMAD 2.0- 3.8 μm) and, thus, show potential for an application as inhalable tuberculosis therapy. The drug release showed the biphasic pattern of release, i.e., initial burst (30-45% up to 8 h) followed by a slower sustained release pattern (more than 80% up to 72 h) in both simulated lung fluids. Optimized formulations exhibited lower cytotoxicity and bio distribution studies demonstrated the efficiency of m-CAMs for spatial delivery of INH to alveolar tissues. CAMs and m-CAMs evidenced minor cytotoxicity on lung epithelial cells (A549 cell lines). Conclusion: m-CAMs thus has a promising potential to be explore as an effective carrier system for delivery of antitubercular drugs regimen. Key words: Targetability, alveolar macrophage, lung cancer A549 cell

    Background: Idiopathic clubfoot is one of the most common and complex congenital deformities which are difficult to correct. Aims and Objectives: The present study was designed to assess the effectiveness and results of the Ponseti method’s early use in the treatment of idiopathic congenital talipes equinovarus (CTEV). Materials and Methods: Seventy-six feet in 50 patients of CTEV during the period of May 2019–May 2020 were studied. All the cases were treated by Ponseti technique. Children with idiopathic CTEV and age <1 year were included in our study. The severity of deformity was graded according to Pirani scoring system both at the beginning and at the end of treatment. Results: The mean age at presentation was 2.77 months. The mean initial Pirani score at time of presentation was 4.07, and at last follow-up was 0.13. We observed that 63 feet (82.89%) out of 76 feet required a percutaneous TA tenotomy along with plaster casting to correct the equines deformity. The mean total number of casts required to correct the deformity was 6.4. The mean duration of treatment from 1st plaster cast to cast for equinus correction was 8.4 weeks. About 94% of cases had a good outcome at last follow-up which was evaluated on the basis of Pirani score. The association of duration of treatment (weeks) with age and total number of cast with age has P=0.002 which was found to be significant. Conclusion: The Ponseti technique is a very safe, efficient, and acceptable economical treatment for the correction of CTEV that gives excellent results on conservative treatment and in most of the cases avoid surgical intervention if protocol followed as prescribed. If the age of the patient is higher at time of presentation, it requires a longer casting period and more number of casts to correct the deformity compared to younger children with the early presentation

    Root canal sealers that possess good antimicrobial property can prevent residual and recurrent infection and contribute to successful endodontic therapy. This study evaluated the antimicrobial activity of four endodontic sealers, AH Plus, Tubliseal EWT, EndoRez, and iRoot SP, against three different microorganisms, E. faecalis, C. albicans, and S. aureus, by direct contact test. 10 μL microbial suspensions were allowed to directly contact the four endodontic sealers for 1 hr at 37°C. Subsequently microbial growth was measured spectrophotometrically every 30 min for 18 hours. The microbial suspensions were simultaneously tested to determine the antimicrobial effect of components which are capable of diffusing into the medium. The results revealed that AH Plus and iRootSP had significantly higher antimicrobial activity against E. faecalis. AH Plus and Tubliseal EWT showed significantly higher antimicrobial activity against C. albicans and S. aureus compared to iRoot SP and EndoRez. EndoRez showed the least antimicrobial activity against all the three microorganisms. Inhibition of microbial growth is related to the direct contact of microorganisms with the sealers. In conclusion AH Plus had significantly higher antimicrobial activity against E. faecalis, C. albicans, and S. aureus
