The traditional System of medicine comprises a wide variety of formulations for various ailments. It is essential to Standardize Ayurvedic drugs so that drugs having good quality can be used for better effect. Standardization is not only limited to the final preparation, but it also includes the materials used during the development and SOP adopted and the equipment used. The present study is an attempt to prepare anti anaemic herbomineral nanoceutical by two different processes, and to standardize and evaluate the haemopoietic effect of the prepared formulations and compare with a marketed formulation. Preparation was done based on Ayurveda Pharmacopoeia. Formulations were characterized by conventional methods and by AAS, XRD, EDAX, SEM, TGA, and IR.  The toxicity and anti-anaemic effectiveness are evaluated by using albino Wister rats and histopathology and cytotoxicity studies. Products have a crystalline nature (XRD). TGA shows the decomposition temp of ferric oxide. SEM EDAX revealed surface smoothness and nano to the micro size of particles. AAS shows that the elements are within the prescribed limits. The in-process Standardization shows the effectiveness of adjuvants. There is an increase of haemoglobin and body weight on day 75 for first preparation than the Second and were comparable to that of standard. No toxicity in all rats and indicated no renal and gastrointestinal toxicity.  The size, smoother surface, and the therapeutic effectiveness of the herbominerals prepared by the two methods can be attributed to the calcination steps and adjuvants. Thus, maybe dose reduction and rapid effect can be achieved.

ABSTRACT Introduction Beauty standards in today's modernized world scenario are formed by well-aligned and well-designed bright white teeth. One of the major reasons behind patients reporting to dental clinics is pain. Caries in the anterior primary teeth forms one of the major concerns from a restorative point of view. Very few studies are quoted in literature which stresses on the follow-up of anterior restorations in primary teeth. Hence, we evaluated and compared the efficacy of composite resin and resin-modified glass ionomer cement (RGIC) for class III restorations in primary anterior teeth. Materials and methods The present study was conducted in the pediatric dental wing and included a total of 80 patients aged 3 to 5½ years who reported with the chief complaint of carious lesions in the primary anterior teeth. Patients having minimal of a pair of similar appearing small carious lesions on the same proximal surfaces of the deciduous maxillary incisors were included for the study. All the patients were randomly divided into two groups: One in which RGIC restoration was done and other in which composite restoration was done. Cavity preparation was done and filling of the cavity with the restorative materials was carried out. Assessment of the restorations was done at 4, 8, and 12 months time following criteria given by Ryge et al. All the results were analyzed by Statistical Package for the Social Sciences (SPSS) software. Mann–Whitney test and one-way analysis of variance (ANOVA) were used to evaluate the level of significance; p value less than 0.05 was considered as significant. Results For composite and RGIC restorations, the mean score for anatomic shape was 1.21 and 1.10 respectively. While comparing the clinical parameters, nonsignificant results were obtained between composite and RGIC restorative materials at 4-, 8-, and 12-month interval. On comparing the clinical parameters for individual restorative materials at different time intervals, statistically significant results were obtained only for anatomical shape and form. Conclusion Both RGIC and composite resin restorative materials showed acceptable clinical outcomes after 12 months of follow-up in deciduous anterior teeth. In restoring class III restorations in primary anterior teeth, both the restorative materials showed similar outcome.

This research examines solution to overcome the problems of opposition to growing vegetables under protected cultivation, This particular example was chosen to illustrate several important aspects of greenhouse production and marketing that affect profitability such as high prices of vegetable seeds, high prices of materials used in the sterilisation (methyl bromide gas), high prices of plastics in addition to low quality and short duration of use, etc.The study depended on Bossali protected agriculture unit as example of application to measure the performance and efficiency of production and revenue during the period 1994-2006. Using the traditional system of protected cultivation, compared with a new system of performance and management of production processes, depends on the cultivation of some fruit crops under protected cultivation during the period 2007-2015.The study analysed the structure cost of production per greenhouse also discussed some economic indicators such as: farm gate prices, total revenue, total costs and net return of cucumber and sweet pepper (as example for vegetables) and navel orange and keitt mango (as example for fruits). This enterprise budget illustration indicates a lack of profitability of this greenhouse vegetable enterprise using these particular assumptions regarding cost, price, and total revenue. Results revealed that net return reached 1234, 3466 Egyptian pound (LE)/greenhouse (540 m2) in navel orange and keitt mango respectively during the study period.

ABSTRACT Introduction Ample radiopacity in order to distinguish from the surrounding tissues is a desirable property of dental graft materials. A total of 15 bone graft materials’ (BGMs) opacities were analyzed in this study. Materials and methods Graft materials were placed in the implant cavity (5 × 10 mm) in cadaver's mandible respectively. Cavity was exposed by using periapical film and a dental X-ray machine at 70 kVp and 8 mA. The optical density of the radiographic images was measured with a transmission densitometer. One-way analysis of variance (ANOVA) was conducted for statistical analysis. Results Among the materials tested, the most radiolucent bone grafts were Grafton and Allogenix with a statistical significance of p ≥ 0.05. 4Bone and Bego Oss exhibited the highest radiopacity with a statistical significance of p ≥ 0.05. Inadequate radiopacity of the dental graft materials may lead to confusion among clinicians in the radiographical follow-up. Among 15 BGMs tested, only three had higher density than bone tissue. Conclusion The radiopacity of the BGM was found to be higher than bone at only three of them. How to cite this article Kursun-Çakmak ES, Akbulut N, Öztas DD.

Abstract The current investigation reports on a green route, simple and eco-friendly method for synthesis of silica nanoparticles from Phyllantus emblica. Appropriate characterization techniques were employed to assess the crystalline nature, microstructure, size, purity, elemental composition and stability of as-biosynthesized silica nanoparticles. The XRD analysis showed a wide-ranging peak at 22∘ of 2θ value and proved that the nanoparticles were crystalline nature with 32 nm average size of particles. FT-IR studies confirmed the occurrence of metal oxide group and presence of phyto-molecules namely hydroxyl, amide, and carboxyl functional groups, which were responsible for formation and stabilization of silica nanomaterials. TGA and Zeta potential analysis determined that silica nanoparticles are highly thermostable. EDX analysis revealed the purity of nanomaterials and spectra confirmed that formation of silica nanomaterials (72.97 weight percentage of SiO2 content) with low impurities. SEM analysis shows that the particles are spherical in shape with low agglomeration. This research work concluded that the P. emblica was an excellent and reliable green resource for production of highly stable and potential silica nanoparticles.

Most lovebirds (Agapornis spp.) have no distinct sexual dimorphic traits. The objective of the paper was to compare the results of two sexing methods, surgical sexing by celioscopy and DNA sexing by PCR from blood samples, in order to evaluate their effectiveness. Materials used to carry out the studies were a 2.7 mm telescope and endoscopy unit, surgical instruments and DNA sampling kits provided by Exomed.cz laboratory. Forty-two lovebirds were included in this study. The endoscopic sexing procedure was performed by the method described by Divers. Blood sampling for DNA testing by PCR method was performed from the metatarsal vein. The results were different in the case of one lovebird, endoscopic sexing revealed it as male, compared to DNA testing, where it was identified as female. DNA sexing is a non-invasive method that might be more accurate than celioscopy in this species, and bird owners have easier access to it.

X-Ray fluorescence computed tomography (XFCT) is an emerging biomedical imaging technique, which demands the development of new contrast agents. Ruthenium (Ru) and rhodium (Rh) have spectrally attractive Kα edge energies, qualifying them as new XFCT bio-imaging probes. Metallic Ru and Rh nanoparticles are synthesized by polyol method, in the presence of a stabilizer. The effect of several reaction parameters, including reaction temperature time, precursor and stabilizer concentration, and stabilizer molecular weight, on the size of particles, were studied. Resultant materials were characterized in detail using XRD, TEM, FT-IR, DLS-zeta potential and TGA techniques. Ru particles in the size range of 1–3 nm, and Rh particles of 6–9 nm were obtained. At physiological pH, both material systems showed agglomeration into larger assemblies ranging from 12–104 nm for Ru and 25–50 nm for Rh. Cytotoxicity of the nanoparticles (NPs) was evaluated on macrophages and ovarian cancer cells, showing minimal toxicity in doses up to 50 μg/mL. XFCT performance was evaluated on a small-animal-sized phantom model, demonstrating the possibility of quantitative evaluation of the measured dose with an expected linear response. This work provides a detailed route for the synthesis, size control and characterization of two materials systems as viable contrast agents for XFCT bio-imaging.
