In the Edo period (1603–1867), the hilts of naginata were often cut off and made into katana or wakizashi (short sword). This practice of cutting off the hilt of an ōdachi, tachi, naginata, or nagamaki and remaking it into a shorter katana or wakizashi due to changes in tactics is called suriage (磨上げ) and was common in Japan at the time.
Brachydactyly type D, also known as short thumb, [3] [1] stub thumb, [5] [6] or clubbed thumb, [5] [6] is a genetic trait recognised by a thumb being relatively short and round with an accompanying wider nail bed. The distal phalanx of such thumbs is approximately two-thirds the length of full-length thumbs.

Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.

Nail growth record can show the history of recent health and physiological imbalances, and has been used as a diagnostic tool since ancient times. [20] Deep, horizontally transverse grooves known as "Beau's lines" may form across the nails (horizontal, not along the nail from cuticle to tip). These lines are usually a natural consequence of ...
Haematopoietic stem cell transplantation (HSCT) is the transplantation of multipotent haematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. [10] [11] [12] It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical ...
