The femoral stem of the hip implant is composed of metal. The stem can also have a porous coating. Describe the porous coating concerns for titanium.
Homework Answers
POROUS COATING CONCERNS FOR TITANIUM: Titanium porous coating is frequently used as a material in orthopaedic for surgical implant purposes and their aim was to determine processing parameters to produce the porous coatings with adequate microstructure for implant fixation. It is considered as an alternative to cement fixation. The biological fixation of an implant requires a rough surface with an open porosity in which the bone cell grow on and grow in. On the other hand, it decreases the overall stability and form the basis for a permanent connection between metallic implants and the bone cells. This quick osseointegration allows for shorter recovery time and less pain for patients in need of replacement implants.

total hip devices. The manufacturer of the Ti-6Al-4V alloy has two
methods from which you can choose for making your hip stems. In
examining samples made by each method, you observe the following
microstructures for method A (top) and method B (bottom)
respectively. Which method will you choose and why?

please critique this post and ask one question relating to this post Stem cell or also known as immortal cell can self-renew (duplicate) or differentiate (specialize) which means it can turn into an organ cell. (Krimsky, 2015) For instance, if we have an stem cell in the liver and the liver needs a new cell, the stem cell will duplicate and one is going to be a duplicate of the original the other one's going to be a new liver...

Ashish Roshan, a 32-year-old man, arrives for first-time visit with complaints of hip pain. His girlfriend, Ana, is with him. One year ago, Ashish had a displaced left femoral neck fracture requiring total hip arthroplasty. Post-surgery, he has had chronic hip pain. For a while, his pain was managed by his orthopedist, originally with oxycodone and more recently with ibuprofen. Ashish complains that now his primary care physician will not refill his oxycodone prescription. He states that only the oxycodone...

As effective as antipsychotic medications can be, they can also have serious side effects. Please explain the rationale for ordering a lipid panel, HGBA1C, liver function tests, and fasting blood sugars for patients who are taking antipsychotics. Also, please describe at least one screening tool that could be used to assess side effects in patients who are taking antipsychotic medications (include a link if available online).
