After bone implant, short-term complications can lead to a complicated approach to recovery, requiring surgical correction associated with additive risks, such as deep infection and double fracture. The development of synthesized biomaterials for bone replacement or repair, as well as the prevalence of osteoporosis, bone fracture, and bone cancer,...

The critical size of bone defects resulting from disease or fractures is a medical problem, usually unable to repair spontaneously by the body's healing mechanisms. Bioceramics are being used for bone tissue regeneration to stimulate the growth of bone cells and guide osseous remodeling. The three most common types of bioceramics used in bone tissu...

s: The objective of this study is to demonstrate how the effect of adding multi-walled carbon nanotubes (MWCNTs) nanoparticles to the (Hydroxyapatite /High-density polyethylene) bio-composites. In this investigation, the samples with various percentages of (MWCNTs) were fabricated by a hot-press technique. The morphological characteristics, roughne...

The healing of bone fractures naturally occurs without surgical intervention. Some damage and fractures in bone tissue are complex and leave remnant deformation, which requires bone replacement material. Hydroxyapatite (HA) is the main element of the bone mineral form and consider as a bioactive material that supports bone growth. Nevertheless, the...

In this investigation, multi-wall carbon nanotubes (MWCNTs) with various percentages including 0.6, 1, 1.4 and 2 % were combined into high-density polyethylene (HDPE 60 w/%) and hydroxyapatite (HA 40 w/%) to form a biocomposite, using hot-press techniques. The surface topography shown by AFM images illustrates the differences in the roughness of th...

Due to the predominance diseases such as bone fracture, bone cancer, and osteoporosis Worldwide. There is a developing requirement for synthesizing biomaterials for bone repair or substitute due to the predominance of bone fracture, bone cancer, and osteoporosis. In this study, multi-wall carbon nanotubes (MWCNT) of (0.6%, 1%, 1.4%, 2%) wt.% and Hi...

The heart is the most important muscular organ in human's body, which pumps blood through the arteries to supply the body with oxygen and nutrients. The heart is supplied by the coronary blood vessel; therefore, the effect of aneurysm and stenosis in left coronary artery on the velocity of blood, wall shear stress of artery and mass flow rate of bl...

The diabetic foot is considered one of the long term diabetes complications caused by a defect in blood vessel and nerve system. This requires dealing with diabetic foot with professional medical care, so as to prevent its development in advanced stages which could end to gangrene and amputation of the foot. This study has been initiated through fo...

The main aim of the study presented in this paper is to determine the characteristics of synovial fluid film region by modeling the human ankle joint to obtain an analytical expression for the pressure distribution, load carrying capacity, coefficient of friction and reduction of synovial film thickness with time of approach. Thus in order to reach...
