Locally released small (non-protein) ninhydrin-reacting molecules underlie developmental differences of cultured medullary versus spinal dorsal horn neurons.

Yu-Feng Xie et al.

Journal of neurochemistry, 122(3), 605-618 (2012-05-23)

Neurons located in the trigeminal subnucleus caudalis (Vc) play crucial roles in pain and sensorimotor functions in the orofacial region. Because of many anatomical and functional similarities with the spinal dorsal horn (SDH), Vc has been termed the medullary dorsal

Moistened hands do not necessarily allude to high quality fingerprints: the relationship between palmar moisture and fingerprint donorship.

Joseph Almog et al.

Journal of forensic sciences, 56 Suppl 1, S162-S165 (2011-01-14)

We explored the quality distribution of ninhydrin-developed prints on A4 bond paper in two groups of individuals, in Israel and in India. While the quality distributions of the developed marks in both countries had some dissimilarities, both groups showed the

A viscoelastic chitosan-modified three-dimensional porous poly(L-lactide-co-ε-caprolactone) scaffold for cartilage tissue engineering.

Chao Li et al.

Journal of biomaterials science. Polymer edition, 23(1-4), 405-424 (2011-02-12)

Biomaterials have been playing important roles in cartilage regeneration. Although many scaffolds have been reported to enhance cartilage regeneration, none of the scaffolds available are optimal regarding mechanical properties, integration with host cartilage and providing proper micro-environment for chondrocyte attachment
