Knowing the morphology of Copper nanoparticles was confirmed by Field Emission Scanning Electron microscopy (FE-SEM). Herein, we are reporting a novel biological approach for the formation of copper nanoparticles using leave. Copper sulfate was made to reduce with an aqueous solution of Cassia auriculata leave extracts. X-Ray diffraction (XRD) pattern reveals the formation of Copper nanoparticles, which shows crystallinity. Field emission scanning electron microscopy (FE-SEM) suggested particles size and spherical shape in the range of 38.1-43.5 nm. UV absorption studies of copper nanoparticles showed that have absorbance in the range 488.5 to 514.3 nm and FT-IR studies of copper nanoparticles were showed that the stretching frequency of fingerprint region at 509.21 cm-1 for Cu-O...

Introduction: Oral rehydration therapy is a life-saving intervention to save the lives of children. However, millions of children die every year due to failure to replace body fluid effectively. Therefore, this study was aimed to assess knowledge, attitude, and practice (KAP) of caretakers towards ORS on the management of diarrhea among under-five children in Aysaita town, Afar Regional State, Ethiopia. Methods: A community based cross-sectional study was conducted in May 2016. Data were collected using a pretested structured questionnaire. The data were cleaned, coded, and entered into EpiData version 3.02 and exported to SPSS version 20 statistical package for analysis. Then descriptive statistics were used to describe the study variables. Results: One hundred seventy-two (72.9%) of the study, children had diarrhea at least once in their lifetime. Two hundred twelve (89.8%) of the caretakers had defined diarrhoea as passing of three or more watery stool. Furthermore, 164 (69.5%) of the care takers knew at least one danger sign of dehydration. Of 172 study children who had diarrhoea at least...

One of the important aspects of modern toxicology research is the prediction of toxicity of environmental pollutants from their molecular structure A Quantitative Structure Toxicity Relationship (QSTR) study was applied to a dataset of 35 polychlorinated dibenzofurans (PCDFs) to investigate the relationship between toxicities of the compounds and their structures. The molecular descriptors were obtained by Density Functional Theory (DFT) (B3LYP/6-31G*) level of calculation. The QSTR model was built using Genetic Function Algorithm (GFA) method. The model with the best statistical significance (N = 24, Friedman LOF = 0.361, R2 = 0.963, R2adj. = 0.955 R2cv = 0.889, R2pred= 0.8286, P95% ˂ 0.05) was selected. The accuracy of the model was evaluated through Leave one out (LOOV) cross-validation, external validation using test set molecules, Y-randomization, and applicability domain techniques. The prediction results are expected to be useful in predicting and identify structural features responsible for the toxicity of the chemicals and other congeneric compounds that fall within the model’s applicability...

Aim: To study the errors during processing on temporary partial denture. Objectives: To assess the errors during processing on temporary partial denture done by Saveetha Dental College students. Materials and Methods: A questionnaire for assessing the errors in processing temporary partial denture containing 24 questions are administered. The participants are dental students from Saveetha Dental College. Background: Temporary partial dentures are for patients who are missing some of their teeth on a particular arch. Certain kinds of removal partial dentures can be used as permanent tooth replacement system especially for people who aren’t candidates for dental implants or fixed bridges. However the same rigidity and thickness that gives these rigid TPDs their durability can make them uncomfortable to wear, while the acrylic material they are made of is capable of staining and breaking. Overtime, the TPDs are prone to become loose-and they are also easy to flip in and out with the tongue. RPDs must be removed regularly for throughout the cleaning. Partial dentures make it easier for you...

Aim: Calotropis procera is a perennial shrub belonging to the family Asclepiadaceae. The aim and objective of the study are to screen the ethanolic, methanolic, and chloroform extract of leaves for their phytochemical constituents and the comparison of the phytochemical components. Further evaluation of fractions of methanolic extracts of C. procera leaf. Methods: The various extracts viz. ethanolic, methanolic, and chloroform of leaves of Calotropis procera screened for the various secondary metabolites like alkaloids, flavonoids, tannins, glycosides, saponin, proteins, etc. the methanolic extract of C. procera was fractionated by using Column Chromatography with ethyl acetate and acetone. Results: The methanolic and chloroform extract of Calotropis procera shows the presence of alkaloids, glycosides, saponins, flavonoids, and proteins. While the ethanolic extract of C. procera shows the presence of alkaloids, tannins, saponins, protein, and flavonoids. The ethyl acetate fractions mainly contain the flavonoids and...
