Background: Environmental concerns are increasing rapidly, and the industry and public are more concerned about natural resources and recycling. Today, it is equally important to take into account cost, ecological factors in production and recycling of materials used in various fields. Purpose: The aim of this study was to evaluate corrosion rate, compositional changes and ion release of recasted Ni-Cr dental casting alloy Materials and Methods: Commercially available Ni -Cr alloy (Bellabond) was used in the study. The recasting was done without any addition of new alloys and recasted up to six times. Corrosion rate was determined by Tafel extrapolation method in artificial saliva in pH 2.3, 6.7 and in 0.9% saline solution at pH 7.3. The compositional changes were studied by Inductively coupled Plasma Atomic emission Spectroscopy (ICP-AES) method. Ion release during storage in artificial saliva and saline solution for one week and four weeks was detected by using atomic absorption spectroscopy (AAS). Results: The corrosion rate was found slightly increased with recasting numbers up to six times. The quantities of ions released increased as the recasting number increases. These changes were not clinically significant. During recasting procedure, there was a change in their alloy compositions, which increases the corrosion rate in recasted alloys. Conclusion: The recasting technique can be accepted in dental practices. This study showed the possibilities of safe usage of recasted alloys up to certain generations in dentistry and in later stages if it is not suitable for dentistry it can be directed to other fields of industries, where the biocompatibility is not a major requirement. This lowers the environmental burden, health hazards and protects imbalance of natural resources

Aim/Background: Plants and plants extracts are employed in cultures for religious purposes, as beauty therapies, in the detection and management/treatment of diseases. Methodology: In this study, an ethnobotanical studies of plants used in detecting pregnancy in Ijebu and Remo areas of Ogun State were carried out using semi-structured to obtain demographic data, local names of plants, the morphological parts used. Also, a phytochemical analysis of two of the identified plants were carried out. A topical and Urine test of plants in detecting pregnancy were designed to mimic procedures used in traditional medicine for detecting pregnancy. Results: Five plant species were identified belonging to the Araceae, Asteraceae, Convulvulaceae, Nyctaginaceae and Rubiaceae were identified in the survey. The identified plants had the use value (UV) of 0.25 (Culcasia scandens), 0.17 (Ipomoea mauritiana), Boerhavia diffusa while Launea taraxacifolia and Chassalia kolly had the use value of 0.08 respectively. Boerhavia diffusa L, Chassalia kolly (Schumach) Hepper tested positive for the presence of flavonoids, alkaloids and tannins. The onset and duration of symptoms of both Boerhavia diffusa and Chassalia kolly leaves at 2000 and 1000mg were dose dependent. The hexane, ethyl acetate and ethanol extracts of Boerhavia diffusa and Chassalia kolly exhibited pruritus and restlessness in the in vivo model while the urine of pregnant women caused black spots on the leaves of Launea taraxacifolia (Willd) Amin Ex.C. Jeffrey. Conclusion: This study reports a rare knowledge of using plants in detecting pregnancy in the Remo and Ijebu areas of Ogun State, Nigeria.

Background and objectives: Solitary thyroid nodule(STN} is a common clinical entity encountered in routine clinical practice.STN is defined as a single swelling involving either lobe of thyroid or isthmus of thyroid gland. Present study was undertaken to know distribution of lesion according to age and sex, and also to evaluate efficacy of FNAC in diagnosis of clinically obvious and palpable solitary thyroid nodule. Method: This study was done on 75cases operated in our hospital from May 2012 to May 2016. All patients included in the study were submitted to FNAC and ultrasonography. All patients were subjected to surgery and histopathology examination was obtained. Results: Out of 75 cases of thyroid lesions, 63 cases were benign (84%), 6 cases were malignant (8%) and 6 cases were suspicious(8%) on FNAC. On Histopathological examination, 60 cases were benign(80%) and 15 cases were malignant(20%). Conclusion: FNAC is a single best investigation for preoperative evaluation for STN to differentiate between benign and malignant nodules with 88% accuracy rate.[Doshi H NJIRM2016; 7(5):53-55]
