Application of umbilical cord blood stem cell transplantation: A better option in regenerative medicine
Extensive research in the field of stem cells has proven the possibility of repairing the damaged tissues and organs. Stem cells can divide and differentiate into various specialized cells. In adult organisms, stem cells act by repairing adult tissues and in a developing embryo, they not only differentiate into all the specialized cells, but also maintain the normal turnover of regenerative organs.Unfortunately the...

Physico-chemical analysis of selected groundwater samples of Ilorin town in Kwara State, Nigeria
This study was conducted to assess the impacts of industrial activities on the ground water quality in industrial and non- industrial area in Ilorin Town. The quality assessment was focused on physico-chemical parameters. Groundwater samples were collected from industrial area and from non-industrial area which were used as control. The results obtained were compared with standards prescribed by WHO. Total of 5...

Fluorescent demonstration of neuronal degeneration in cyanide neurotoxicity through anti protein G-colloidal gold conjugate labeling
The study of the mechanism of neuronal cell death has been an important aspect of cell biology in the last decade. Considering the somewhat non-specific nature of the methods and the complexity of the neuronal cell cycle, a multi-technique approach has been suggested. This study is aimed at describing a method for demonstration of neuronal degeneration in the visual cortex (molecular layer) of adult wistar rats. It...

An intelligence system approach using artificial neural networks to evaluate the quality of treatment planning for nasopharyngeal carcinoma
The quality of the nasopharyngeal carcinoma (NPC) treatment plans evaluation using three types of artificial neural networks (ANNs) are instructed by three different training algorithms. Three ANNs including Elman (ANN-E), feed-forward (ANN-FF), and pattern recognition (ANN-PR) were trained by using three different models, that is, leave-one-out (Train-loo), random selection (Train-random), and user...

Meta analysis of zoledronic acid on the bone markers among osteoporosis patients
Osteoporosis is a skeletal disease that is characterized by compromised bone strength predisposing a person to an increased risk of fracture. Zoledronic acid (ZOL) is an aminobisphosphonate with a high affinity for mineralized bone. This review of relevant meta-analysis aimed to clarify the effect of ZOL in treatment and prevention of osteoporosis. Random control trials that investigated the evidence for the role of ZOL...

Effect of boron carbide on the microstructure and the mechanical properties of segments produced using hot pressing method
In this study, effect of boron carbide (B4C) addition on microstructure and mechanical properties of diamond cutting segments was investigated. For this purpose, the boron carbide addition quantity was changed as 2, 5 and 10 wt%. In all of the experiments, hot pressing process was carried out at 35 MPa, at 700°C and sintering time of 3 min. Microstructure and phase composition of segments were determined by Scanning...
