Clot formation and fibrinolysis assays reveal functional differences among hemostatic agents in hemophilia A plasma.

Background: Measuring the activity of hemostatic agents used to treat hemophilia A often requires drug-specific assays. assays show hemophilic clots have abnormal characteristics, including prolonged clotting time and decreased resistance to fibrinolysis. The ability of certain agents to correct these parameters is associated with hemostatic efficacy .

Adsorbed protein film on pump surfaces leads to particle formation during fill-finish manufacturing.

During fill-finish manufacturing, therapeutic proteins may aggregate or form subvisible particles in response to the physical stresses encountered within filling pumps. Understanding and quantitating this risk is important since filling may be the last unit operation before the patient receives their dose. We studied particle formation from lab-scale to manufacturing-scale using sensitive and robust protein formulations.

Embryonic exposures to mono-2-ethylhexyl phthalate induce larval steatosis in zebrafish independent of Nrf2a signaling.

Mono-2-ethylhexyl phthalate (MEHP) is the primary metabolite of the ubiquitous plasticizer and toxicant, di-2-ethylhexyl phthalate. MEHP exposure has been linked to abnormal development, increased oxidative stress, and metabolic syndrome in vertebrates. Nuclear factor, Erythroid 2 Like 2 (Nrf2), is a transcription factor that regulates gene expression in response to oxidative stress.

Scrotal hematocele as an unusual presentation of blunt abdominal trauma in three male infants.

Three infants presented with bluish discoloration and swelling of the scrotum with no history of scrotal trauma. Sonography revealed unilateral hematoceles in 2 cases and bilateral hematoceles in the third. All 3 infants had intact testes.
