Vitamin D exhibits complex and cell‐specific biological effects in multiple tissues via activation of the ligand‐sensing transcription factor vitamin D receptor (VDR). The photo‐switchable vitamin D mimetic 10 transitions between VDR antagonist (E) and agonist (Z) activity upon illumination and offers unprecedented bidirectional optical control over ...

Polarized microscopic images of the outer bone cortex (a and b) and deeper trabecular bone (c and d) of the deer calcaneus in thin cross‐sections. The brighter gray levels reflect more oblique‐to‐transverse collagen fibers in the compression/dorsal bone (a, c) and the darker gray levels reflect more longitudinal collagen in the tension/plantar bone (b,

Inhibitory effect of bovine milk osteopontin on the initial attachment of Streptococcus mutans
We investigated the effect of bovine milk osteopontin (OPN) on the initial adhesion of Streptococcus mutans to hydroxyapatite. Hydroxyapatite pellets were immersed in a 5.4 µM OPN solution at 37°C for 30 min.

Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...
