It is reported to occur in ~4-6% of all deliveries, and the risk is significantly greater with caesarean delivery than vaginal delivery. Oxytocin is universally accepted as drug of choice but carboprost has also been found to be effective in management of third stage of labour. Carboprost 250 microgram (μg) is associated with significant side effects; however its lesser dose may prove a better uterotonic with fewer side effects. Aims and objective: To evaluate the role and scope of using prophylactic intramuscular carboprost [125 μg] in comparison with intramuscular oxytocin [10 units] in prevention of PPH in caesarean section. Material and methods: 200 pregnant women admitted in labour room undergoing caesarean section were included in this study after taking informed consent and were randomly divided into group 1 and 2, where Group 1 receiv...

Materials and Methods: According to the file systems used for canal preparation, eighty mesiobuccal canals of mandibular molars were distributed into four groups (20 samples each): OS (Group 1), F360 (Group 2), Wave One (Group 3), and reciproc (Group 4). According to the manufacturer's instructions, all groups were prepared until size 25 taper. Canals were scanned using CS three-dimensional CBCT scanner (Carestream) before and after preparation at 2 mm, 5 mm, and 8 mm from the apex. The data collected were evaluated using SPSS software with ANOVA and post hoc for a significant difference. Results: Significant difference was found between the entire group at 2 mm and 5 mm (P = 0.021) and at 8 mm (P = 0.037), where F360 showed the least canal transportation. The mean values for centering ability were not found significant at 2 mm and 5 mm. OS proved to remain more centered than the other groups. Curved canals were instrumented better with minor canal straightening by using Reciproc. The dentin was removed more by using Wave One, whereas least dentin was removed by F360. During pre- and post-instrumentation scans the change in volume of the root canal were not found statistically significant. Wave One showed the maximum increase in the volume of the canal after instrumentation. For the preparation of the canal, the time taken was less with reciproc as compared to other groups. Conclusion: Therefore, according to the study single-file rotary instrument like F360 used in the continuous rotation is suitable instrument for the root canal preparation followed by Reciproc, OS, and Wave One.
New triphenyltin(IV) hydroxamate complexes, [Ph 3 Sn(4-NO 2 CnH)] (1) and [Ph 3 Sn(4-NO 2 BzH)] (... more New triphenyltin(IV) hydroxamate complexes, [Ph 3 Sn(4-NO 2 CnH)] (1) and [Ph 3 Sn(4-NO 2 BzH)] (2) have been synthesized by the reactions of Ph 3 SnCl with potassium 4-nitrocinnamo hydroxamate [4-NO 2 C 6 H 4 CHCHCONHOK] (KHL 1) and potassium 4-nitro benzohydroxamate [4-NO 2 C 6 H4CONHOK] (KHL 2). The complexes were synthesized in 1:1 molar ratio in MeOH+C 6 H 6 and characterized by physicochemical and IR, 1 H NMR and mass spectrometry. The bidentate hydroxamate involving bonding through carbonyl and hydroxamic oxygen (O, O coordination) has been inferred from IR spectra. The electrochemical behavior of complexes has been analyzed. Quasi-irreversible two electron metal-centered cathodic process of type Sn IV /Sn II redox couple was indicated by cyclic voltammetric technique. The thermal behavior of 1 and 2 studied by TGA have shown continuous decomposition to yield Sn+0.5SnO 2 and SnO 2 as final residues. The in-vitro antimicrobial activity assays of 1 and 2 against pathogenic gram+ve bacteria (Bacillus subtilis and Staphylococcus aureus), gram-ve bacteria (Salmonella typhi and Pseudomonas aeruginosa), and fungi (Aspergillus fumigatus and Alternaria alternata) were doneby MIC method. The complexes have exhibited appreciable antimicrobial activity relative to the respective standard Gentamycin and Nystatin drugs.

The ZnO/ Cu 2 MgO 3 nanocages as anode material are synthesized by one-step cost-effective ultrasonic spray pyrolysis method. The porous outer shell with hollow interior not only offer ease of electrolyte diffusion and fast Li-ion transport, but also buffer the huge volume change during repeated lithiation/de-lithiation process. As a result, this novel anode demonstrates a high discharge capacity (441 mA h g-1 at the current density of 500 mA g À1 even after 400 cycles), excellent cycle stability, and outstanding rate capability.

Materials and Methods: Single-rooted mandibular premolars (sixty) were divided into three groups (n = 20 each) after decoronation at cementoenamel junction. Root canal preparation was carried out using ProTaper rotary files, and sodium hypochlorite in 3% concentration was used for irrigation. Finally, obturation was accomplished with AH plus (Dentsply, Germany) (Group 1), MTA Fillapex (Angeles, Brazil) (Group 2) and Bioceramic (Brasseler, USA, Savannah, GA) (Group 3) sealers and gutta-percha. Fracture point in the root was recorded using universal testing machine. The data were analyzed statistically using one-way analysis of variance. This was followed by pair-wise comparison using Tukey's post hoc test. Results: Bioceramic Sealer showed better fracture resistance. This was followed by MTA Fillapex and AH Plus. However, the results among the three groups were not statistically significant. Conclusion: The highest fracture resistance was offered by Bioceramic Sealer when compared with MTA Fillapex and AH Plus.
