概括
T-TAS HD-Chip有效地评估了骨髓瘤瘤患者的血静功能. 它在预测需要进行血小板输血方面表现有希望,特别是当血小板计数超过20 × 10 ^ 9 / L时.
科学领域:
- 血液学 血液学 血液学
- 血液静止 血液静止 血液静止
- 在瘤学瘤学.
背景情况:
- 血小板输血对于患有血液性恶性瘤的患者至关重要.
- 仅仅是血小板计数不足以预测出血风险.
- 评估静血功能对于患有血栓缩的患者至关重要.
研究的目的:
- 为了研究T-TAS HD-Chip在患有骨髓瘤瘤的血栓细胞缺陷患者中的实用性.
- 评估T-TAS参数与血小板输血需求和出血事件的关联.

Structure and Function of Platelets
7.3K
The cell fragments known as platelets are disc-shaped, with an average diameter of about 3 μm and a thickness of roughly 1 μm. They play a crucial role in the body's vascular clotting system, which also involves plasma proteins, blood cells, and blood vessel tissues.
Platelets are continually replenished, circulating in the bloodstream for 9-12 days before being removed by phagocytes, primarily in the spleen. A microliter of circulating blood contains between 150,000 and 450,000...

Bone Marrow Sampling and Transplants
3.1K
Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.
The transplant begins with high doses of chemotherapy and radiation treatment, which aim to destroy...
