Two-layer sheet of gelatin: A new topical hemostatic agent

Asian Journal of Surgery, 2018
Uncontrolled surgical bleeding is associated with increased morbidity, mortality, and hospital cost. Topical hemostatic agents available today have problems controlling hemostatic effects; furthermore, their handling is difficult and they are unsafe.We devised a new hemostatic agent comprising gelatin sponge and film designed to be applied to the ...

A Hybrid Bioprinting–Microfabrication Approach to Controllable Multitype Spheroid Arrays for Modeling Tumor Heterogeneity

Advanced Healthcare Materials, EarlyView.
This work introduces a “cancer‐in‐a‐well” technology that recreates tumor heterogeneity in vitro using multitype spheroid arrays. Combining bioprinting/microdispensing with microstructured culture devices, the system improves drug screening and modeling of tumor complexity.

Ultrastructure of the Gelatinous Layer in Tension Wood Fibers from Populus euramericana [PDF]

, 1971
木材の細胞膜構造についてより深い知見を得るための一つの課題として, Populus euramericanaの引張あて材のゼラチン層 (以下Gと略記) の微細構造を電子顕微鏡, X線回折法および赤外分光分析法を用いて研究した。試料のゼラチン層は, NorbergとMeierの方法を用いて引張あて材から分離して得た。引張あて材のゼラチン繊維の膜層構成はP+S_1+S_2+Gである。Gの解体試料を負染色して電子顕微鏡で観察した結果 ...
