Vital dye labelling of Xenopus laevis trunk neural crest reveals multipotency and novel pathways of migration [PDF]

, 1993
Although the Xenopus embryo has served as an important model system for both molecular and cellular studies of vertebrate development, comparatively little is known about its neural crest.

Redefining the Skin Barrier: A Microbiome‐Integrated Multilayered Defense Model

Barrier Immunity, EarlyView.
ABSTRACT The skin constitutes a dynamic interface orchestrating a sophisticated multilayered defense system comprising physical, chemical, immune, and microbial barriers. This review synthesizes current understanding of the structural and functional integration of these barriers, emphasizing their synergistic interactions in maintaining cutaneous ...

Structural analysis and spectroscopic characterization of melanin-alginate films

Chemical Physics Impact
In this work, we present the spectroscopic and structural analysis of synthetic melanin incorporated within alginate films. We propose a synthesis methodology for alginate films with different concentrations of melanin.

Current Update and Trends in Melanin Pigmentation and Melanin Biology.

The Keio Journal of Medicine, 1995
Certain aspects of current progress in melanin biology and its possible clinical relevances are reviewed with emphasis on some of our recent research activities. The important aspects discussed are (a) the biological properties of melanin pigments and their relevance to biological functions, (b) functional interaction of melanogenic/melanogenesis ...

Whole tissue imaging of cellular boundaries at sub‐micron resolutions for deep learning cell segmentation: Applications in the analysis of epithelial bending of ectoderm

Developmental Dynamics, EarlyView.
Abstract Background To understand cellular morphology, biologists have relied on traditional optical microscopy of tissues combined with tissue clearing protocols to image structures deep within tissues. Unfortunately, these protocols often struggle to retain cell boundary markers, especially at high enough resolutions necessary for precise cell ...

From One Strand Dyed/Undyed Hair With/Without Root to Fast and Successful STR Profiling and Evaluation With Principle Component Analysis

ELECTROPHORESIS, EarlyView.
ABSTRACT Fallen/shed single hair shafts with/without roots can be encountered as evidence in crime scenes. Identification from hair exhibits serious difficulties, due to the low amount of DNA, PCR inhibitors, and the existence of DNA mostly in degraded forms. Exposure of hair to chemical oxidation, sunlight, etc.
