Numerical Study of the Pedicle Screws’ Pullout: Design of Experiment and Results Processing Using the ‘Taguchi’ Method: OAJBS Publishers

Numerical Study of the Pedicle Screws’ Pullout: Design of Experiment and Results Processing Using the ‘Taguchi’ Method by K Jendoubi* in Open Access Journal of Biomedical Science (OAJBS)

The objective of this research is to use the Taguchi method to study the effects of parameters that affect the pull out of pedicle screws. These parameters are biological-based (normal or osteoporotic bone types, pedicle diameter), design-based (screw’s outer diameter, thread depth, pitch, and shape) and surgical-based (preparation hole, bone-screw contact type). A total of seven (7) parameters having each two (2) levels each. Using 2D axisymmetric finite element computational models, a series of “Taguchi” simulation tests based on an orthogonal L8 [27] lattice is conducted.

Facile Synthesis of Chitosan Nanoparticle with Different Features and Histopathological Ultrastructural Study on The Effect of Its Bio-complex with Bovine Serum Albumin in Mice Liver by Maged El-Kemary* in Open Access Journal of Biomedical Science (OAJBS)   We have synthesized chitosan nanoparticles (CS-NPs) with different characteristics using ionic gelation method. Results showed that the synthesized CS-NPs with different concentrations of trisodium polyphosphate (TPP) are irregular – spherical shaped with narrow size distribution and high stability. The microporous chitosan was also synthesized with new features characterized with different techniques as SEM, EDX, FTIR and BET. The synthesized microporous chitosan has a surface area and pore volume of 245.571m 2 /g and 0.155cm 3 /g respectively. Its microporous surface is functionalized with carboxyl and amine groups. Histopathological and ultrastructural studies of mice liver were performed using optical and scanning electron m...

Review on Analysis of Breast Tumor with Methods of Treatment: OAJBS Publishers

Review on Analysis of Breast Tumor with Methods of Treatment by Nagham Mahmood Aljamali* in Open Access Journal of Biomedical Science (OAJBS) Breast malignance is the greatest public in ladies, with a high incidence in North America and Eastern Europe, medium in Southern Europe and the Middle East and low in the Far East. Breast malignance is the second most common malignance in the world after lung malignance, and since it happens a lot, the doctors asked the women to examine themselves by themselves, in order to discover the signs of the disease early before it spreads. It is possible that this disease can be treated after being diagnosed by a specialized doctor and determining the type of tumor in the breast, and the surgeon removes the breast completely and starts chemotherapy about 6 doses, then radiotherapy, how many sessions will be determined by the doctor, and then hormonal therapy, a medicine called Tamoxafin or any medicine determined by the doctor, and it is possible. This ...
