It builds on previous work by Daniell using genetically modified plants to introduce a protein into the body that would teach the immune system to tolerate clotting factors
that are given as a treatment for hemophilia.
Additionally, the presence of specific inhibitors, commonly targeting factor VIII, can cause clotting factor
Infusing a crystalloid solution (normal saline or lactated Ringer's solution) or stored packed red blood cells without clotting factors
into a hemorrhaging patient will dilute the clotting factors
and can actually make the patient more coagulopathic.
In its bite, the tiger keelback delivers slow-acting salivary toxins, which disable a clotting factor
in the blood of its victims.
Several patients continued to use less clotting factor
after combination therapy stopped.
By all accounts, this represents a dramatic reduction in the amount of reimbursement that provides for blood clotting factor
and a few ancillary supplies.
In 2001, Medicare's outpatient expenditures for blood clotting factor
used to treat the estimated 1,100 beneficiaries with hemophilia totaled about $105 million, or more than 2 percent of total Medicare spending on outpatient drugs.
This project will determine whether blood clotting factor
homologues are expressed in fiber type-specific muscle exposed to the atrophy of simulated microgravity.
Gene therapy appears to partially correct hemophilia in dogs while avoiding an immune reaction that can destroy the life-saving replacement clotting factor
used to treat the disease.
The genetic material included a human clotting factor
and a pig protein.
The five behaviors that qualified as high-risk were, for hemophiliacs, having received clotting factor
concentrations; for men, ever having had sex with another man since 1980; ever having taken street drugs by needle since 1980; ever having traded sex for money since 1980; and ever having had sex with a person who fits any of the above descriptions.
Gene delivery to the liver, where the factor IX clotting factor
is naturally produced, resulted in easily measurable levels of factor IX for the duration of the study (270 days) and no detectable antibodies or other inhibitors of factor IX.
