Mice and human patients with impaired vitamin D receptor (VDR) signaling have normal developmental hair growth but display aberrant post-morphogenic hair cycle progression associated with alopecia. In addition, VDR(-/-) mice exhibit impaired cutaneous wound healing. We undertook experiments to determine whether the stress-inducible regulator of energy homeostasis, DNA damage-inducible transcript 4 (Ddit4), is involved in these processes. By analyzing hair cycle activation in vivo, we show that VDR(-/-) mice at day 14 exhibit increased Ddit4 expression within follicular stress compartments...

PURPOSE: Valproic acid (VPA), a histone deacetylase (HDAC) inhibitor, is also used to manage seizures in glioblastoma patients. HDAC inhibitors can protect normal cells and tissues from the deleterious effects of radiotherapy, and VPA is reported to improve the survival of glioblastoma patients receiving chemoradiation therapy. VPA also promotes hair growth, and thus has the potential to reduce the radiotherapy side effect of hair loss while improving the survival of patients with glioblastoma...

Hair and nails are often used to prove drug intake over several months. However, it is impossible to determine the day of drug intake by conventional segmental analysis of bulk samples. To improve this segmental analysis, we prepared accurate 0.4-mm hair and 0.2-mm nail segments, which correspond to their respective growth rates of 1-2 days, using a tissue slicer. The aim of this study was to develop an efficient method to extract drugs from a single sub-millimeter segment of hair and nail. Hair and nails were collected from a subject who was administered a single dose of chlorpheniramine...

Efr3a has been found to be involved in the functional maintenance and structural degeneration of sensory and motor nervous tissues. Our previous data have suggested that Efr3a may be associated with the initiation of the degeneration of spiral ganglion neurons (SGNs). In this study, we used Efr3a knockdown (Efr3a KD) and Efr3a overexpression (Efr3a OE) mice to determine the role of Efr3a in age-related hearing loss. Measurements of hearing thresholds showed that Efr3a had little or no influence on the hearing threshold at all frequencies in adult mice, whereas in an early stage of senescence, Efr3a reduction resulted in better hearing function, especially at 10 and 12months of age...

The diagnosis of death as a result of starvation is established on anthropological measurements, visual appearance of the deceased on external and internal examination, microscopic analysis, laboratory testing, and exclusion of other causes of death. Herein, we present our findings on a case of 95-year-old man who died of starvation. After the diagnosis of starvation was established by traditional forensic medicine methods, we have conducted retrospective segmental analysis of stable carbon (δ(13) C) and nitrogen (δ(15) N) isotope ratios in hair sample...
