A comparative Study of Functional Outcomes for the Treatment of Arthrosis of the Knee Joint Using Platelet-Rich Plasma Injections After or Without Arthroscopy

The research provides a comparison between two methods for treating osteoarthritis. In the knee joint using platelet-rich plasma injections after or without arthroscopy, the study included 100 cases every fifty of them were treated in one way and the results were evaluated after surgery and the researcher reached the following results. Treatment with platelet-rich plasma injections after arthroscopy provided an advantage in terms of pain reduction and reduced joint effusion in the knee, improvement of the ability to rest on the limb (walking), and a marked reduction in the severity of symptoms and signs of degeneration was noted.

A Theoretical Study of X-ray produced by the Plasma Focus device based on Sing Lee model

The Lee code is applied to characterize the plasma focus in two plasma focus devices UNU/ICTP PFF and Amirkabir plasma focus device (APF), and for optimizing the nitrogen soft x-ray yields based on bank, tubes and operating parameters. It is found that the soft x-ray yield increases with changing pressure until it reaches the maximum value for each plasma focus device, with keeping the bank parameters, operational voltage unchanged but systematically changing other parameters.

dying Landau Damping in dense quantum Plasmas

In This Scientific Paper it had been studied the Effect of Ponderomotive Force on Landau damping of electron Wave in dense quantum Plasmas, by Using quasi quantum kinetic Equation, Using the Corrections due to both of quantum effects and Ponderomotive Force, because of their necessity in Studying Wave Reflection inside Cavity Energy ,and some Physical Properties of Plasmas, then comparing the Results to the other Conclusions in this Field.

Defining the plasma parameters of solid red Copper depending on (LIPS) technique and by using Nd:YAG laser

This paper discuss the Laser induced breakdown spectroscopy (LIBS) by using Nd:YAG which is a high energy pulsed Laser . The laser radiation is focused on solid targets which are samples of red Copper (99.5%). Most important Plasma parameters which are electron temperature and density was measured.

Influence of welding parameters on the thermal cycle of plasma arc welding

In this research, a study of the influence of arc welding parameters on the thermal cycle was conducted, where the thermal cycle within the welded plate of stainless steel 304L by plasma arc welding (PAW) with weld-on-plate was measured using thermocouples for several welding parameters (intensity of the welding current, welding velocity, flow rate of plasma gas) and comparing the influence of this parameters on the thermal cycle within the plate.

Effect of Plasma Arc Welding Parameters on Joints Mechanical Properties of Austenitic Stainless Steel Sheets AISI 316L

Design of experiments (DOE) had been used in the study, and the results had been evaluated by the surface response method. The results showed that the welding current is the main parameter by its effect on the mechanical studied properties and the parameters values which give the best responses had been determined.

Effect of the use of Palatelet-Rish Plasma(PRP) on Periapical Bone repair following Apicoectomy on a sample of patients from the middle area in Syria

This research aims to accelerate the restoration of the bone cavity resulting from the surgical removal of the dental cysts through fill the cavity with Palatelet-Rish Plasma.

Evaluation the participation of hyaluronic acid with platelet-rich plasma in treatment of temporomandibular joint disorders

The aim of this study is to evaluate the clinical outcomes of treatment of temporomandibular joint disorders via injection HA & PRP. The sample consisted of 24 patients with TMD.

Numerical study of soft x-ray yield in two dense plasma focus devices based on Lee code, and comparing it with experimental results using neon filling gas

In this work we carried out some numerical experiments on NX2, UNU/ICTP PFF dense plasma focus device with neon filling gas using Lee code version (RADPFV5.15de.c1) and standard parameters of the devices to compare the value of the soft x-ray yield (Ysxr) emitting from each one. Also we studied the influence some factors on the value of (Ysxr).

The effect of periosteal distraction on osteogensis with the use of Platelet Rich Plasma PRP: An Experimental Study in The Rabbits

This study is aimed to evaluate the role of Platelet Rich Plasma PRP on osteogensis in periosteal distraction. The sample consisted of 12 rabbits from local spices. The sample divided equally into two groups, titanium mesh with holes was used in to elevate the periosteum and the space between the surface of bone and the mesh was filled with collagen sponge, in the test group the sponge was injected with PRP. The rabbits were killed after eight weeks after operation and the samples were prepared for histological study. The histological study of specimens of control group showed formation of small island of osteoid with large areas of connective tissue. While, in test group there was an increasing in bone formation in form of wide area of woven bone and decreasing in connective tissue. We conclude that application of Platelet Rich Plasma PRP lead to improvement in bone formation in periosteal distraction.
