Initial investigation on the feasibility of porcine red blood cells from genetically modified pigs as an alternative to human red blood cells for transfusion.

The decline in blood donation rates and the ongoing shortage of blood products pose significant challenges to medical societies. One potential solution is to use porcine red blood cells (pRBCs) from genetically modified pigs as an alternative to human red blood cells (hRBCs). However, adverse immunological reactions remain a significant obstacle to their use.

Recent trends in perioperative blood transfusion during elective kidney transplantation.

Background: Accurately predicting the demand for blood transfusions is crucial for blood banks. Given the potential for emergency situations, it is imperative that blood banks maintain a sufficient inventory of blood products. In this study, we examined the use of perioperative transfusions in patients undergoing elective kidney transplants.

Correction of superior sulcus deformity with orbital fat anatomic repositioning and fat graft applied to retro-orbicularis oculi fat for Asian eyelids.

Background: "Sunken eyelid" is a term used to describe a deeply sunken area between the upper eyelid and upper edge of the orbital bone. The condition frequently is accompanied by blepharoptosis. Correction of a "sunken eyelid" generally is performed with a fat graft.

Results of long-term follow-up observations of blepharoptosis correction using the palmaris longus tendon.

Background: The frontalis sling procedure is a useful approach for correcting severe blepharoptosis. However, blepharoptosis often recurs after corrective surgery using the tensor fascia lata. Good results without recurrence after a modified Fox method were obtained using the palmaris longus tendon.
