TL;DR: Considering the ever increasing popularity of tattoos, significant reactions remain unusual and red pigments are the commonest cause of delayed tattoo reactions.
Abstract: Considering the ever increasing popularity of tattoos, significant reactions remain unusual. Red pigments are the commonest cause of delayed tattoo reactions. Histology typically shows extensive lichenoid basal damage, well away from the dermal pigment. We report two cases of lichenoid reactions to red tattoo pigment and review the literature on the subject.

TL;DR: Its role in biological systems may be more subtle with nitration of key tyrosine residues likely to profoundly affect cellular function such as signaling cascades and further advances are likely to be made in the localization of NTYR residues in peptide fragments using mass spectrometry.

TL;DR: To investigate whether inhaling 50% xenon during hypothermia (HT) offers better neuroprotection than xenon or HT alone, xenon and HT alone are studied.
Abstract: Objective
To investigate whether inhaling 50% xenon during hypothermia (HT) offers better neuroprotection than xenon or HT alone.
Methods
Ninety-eight newborn pigs underwent a 45-minute global hypoxic-ischemic insult severe enough to cause permanent brain injury, and 12 pigs underwent sham protocol. Pigs then received intravenous anesthesia and were randomized to 6 treatment groups: (1) normothermia (NT; rectal temperature 38.5°C, n = 18); (2) 18 hours 50% xenon with NT (n = 12); (3) 12 hours HT (rectal temperature 33.5°C, n = 18); (4) 24 hours HT (rectal temperature 33.5°C, n = 17); (5) 18 hours 50% xenon with 12 hours HT (n = 18); and (6) 18 hours 50% xenon with 24 hours HT (n = 17). Fifty percent xenon was administered via a closed circle with 30% oxygen and 20% nitrogen. After 10 hours rewarming, cooled pigs remained normothermic until terminal perfusion fixation at 72 hours. Global and regional brain neuropathology and clinical neurological scores were performed.
Results
Xenon (p = 0.011) and 12 or 24 hours HT (p = 0.003) treatments offered significant histological global, and regional neuroprotection. Combining xenon with HT yielded an additive neuroprotective effect, as there was no interaction effect (p = 0.54). Combining Xenon with 24 hours HT offered 75% global histological neuroprotection with similarly improved regional neuroprotection: thalamus (100%), brainstem (100%), white matter (86%), basal ganglia (76%), cortical gray matter (74%), cerebellum (73%), and hippocampus (72%). Neurology scores improved in the 24-hour HT and combined xenon HT groups at 72 hours.
Interpretation
Combining xenon with HT is a promising therapy for severely encephalopathic infants, doubling the neuroprotection offered by HT alone. ANN NEUROL 2010

TL;DR: The differential expression of ERα, ERβ and AR in human skin suggests that the mechanisms by which steroid hormones mediate their effects may be more complex than previously thought and provides further evidence for oestrogen action in non‐classic target tissues.
Abstract: Oestrogens play a major role in non-classic target tissues in both sexes, yet there have been few studies on estrogens and skin. Recently a second oestrogen receptor (ERbeta) has been discovered. Therefore, we have compared the expression of oestrogen receptor alpha (ERalpha), beta (ERbeta), the androgen receptor (AR) and a cell proliferation marker in male and female non-balding scalp skin. ERbeta was the major steroid receptor expressed in human skin. It was highly expressed in epidermis, blood vessels and dermal fibroblasts, in contrast to ERalpha and AR. In the hair follicle, ERbeta expression was localized to nuclei of outer root sheath, epithelial matrix and dermal papilla cells, in contrast to ERalpha, and the AR, which was only expressed in dermal papilla cells. Serial sections also showed strong nuclear expression of ERbeta in the cells of the bulge, while neither ERalpha nor AR was expressed. In the sebaceous gland, ERbeta was expressed in both basal and partially differentiated sebocytes. ERalpha exhibited a similar pattern of expression, while the AR was expressed in the basal and very early differentiated sebocytes. There was no obvious difference in the expression of either oestrogen receptor in male or female skin. The wide distribution of ERbeta in human skin suggests that oestrogens may play an important role in the maintenance of skin and in the regulation of the pilosebaceous unit, and provides further evidence for oestrogen action in non-classic target tissues. The differential expression of ERalpha, ERbeta and AR in human skin suggests that the mechanisms by which steroid hormones mediate their effects may be more complex than previously thought.
