Increase of SERS Signal Upon Heating or Exposure to a High-Intensity Laser Field: Benzenethiol on an AgFON Substrate

The surface-enhanced Raman scattering (SERS) signal from an AgFON plasmonic substrate, recoated with benzenethiol, was observed to increase by about 100% upon heating for 3.5 min at 100C and 1.5 min at 125C. The signal intensity was found to increase further by about 80% upon a 10 sec exposure to a high-intensity (3.2 kW/cm^2) 785-nm cw laser, corresponding to 40 mW in a 40+/-5-um diameter spot. The observed increase in the SERS signal may be understood by considering the presence of benzenethiol molecules in an intermediate or 'precursor' state in addition to conventionally ordered molecules forming a self-assembled monolayer. The increase in the SERS signal arises from the conversion of the molecules in the precursor state to the chemisorbed state due to thermal and photo-thermal effects.Comment: 9 pages, 4 figures; J.

Fetal adnexa-derived stem cells application in Horse model of tendon disease

The equine superficial digital flexor tendon is a frequently injured structure that is functionally and clinically equivalent to the human Achilles tendon. Both act as critical energy-storage systems during high-speed locomotion and can accumulate exercise- and age-related microdamage that predisposes to rupture during normal activity. The biology of tendon and its matrix, and the pathological changes occurring in the context of early injury in both horses and people are reviewed. In addition, this review focuses on the current use of stem cells (MSCs), recovered from either bone marrow or adipose tissue to treat strain-induced tendon injury in the horse with particular interest to non-embryonic extra-fetal-derived stem cells that open new perspectives for developmental biology and for regenerative medicine
