*Jerry Bergman, Ph.D., Northwest State College 22-600 State Rt 34, Archbold, OH 43543 Received April 4, 2003; Revised October 13, 2003 Mammal body hair is a complex structure that involves several basic parts, including a shaft, a root, and a follicle. The most common theory currently in vogue is that hair evolved from reptile scales. Although both scales and hair preserve well in the fossil re...

Current methods of forensic hair analysis rely upon comparisons of either hair morphology or DNA. Microscopic examination of hair can indicate species, race, body and method of removal. However, determining the age and gender of a subject based on hair morphology is not widely accepted. In forensic medicine sex from hair can be determined in decomposed bodies and mutilated bodies. Root sheath c...

The rough coat (rc) spontaneous mutation causes sebaceous gland (SG) hypertrophy, hair loss, and extracutaneous abnormalities including growth retardation. The rc mice have a missense mutation in the predicted Ig protein Myelin Protein Zero-Like 3 (Mpzl3). In this study, we generated Mpzl3 knockout mice to determine its functions in the skin. Homozygous Mpzl3 knockout mice showed unkempt and gr...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Panfolliculoma is a distinctive and unusual benign follicular neoplasm. It shows differentiation towards all components of the hair follicle, including the upper and the lower segments. We report two cases of this rare disease. The first patient presented with a painful nodule on the scalp and the second patient had an asymptomatic skin-colored nodule on his left eyebrow. Histopathologic examin...

The expression of retinoid-acid-related orphan receptor α (RORα) was evaluated at the mRNA level using real-time polymerase chain reaction (qRT-PCR), and its expression localization was determined by in situ hybridization of adult Inner Mongolian cashmere goats at different times of the year. In situ hybridization demonstrated that RORαwas expressed in secondary hair follicles of the hair shaft...

iRhom1 and iRhom2 are inactive homologues of rhomboid intramembrane serine proteases lacking essential catalytic residues, which are necessary for the maturation of TNFα-converting enzyme (TACE). In addition, iRhoms regulate epidermal growth factor family secretion. The functional significance of iRhom2 during mammalian development is largely unclear. We have identified a spontaneous single gen...

Hair morphology is highly differentiated between populations and among people of European ancestry. Whereas hair morphology in East Asian populations has been studied extensively, relatively little is known about the genetics of this trait in Europeans. We performed a genome-wide association scan for hair morphology (straight, wavy, curly) in three Australian samples of European descent. All th...

Bone morphogenetic protein (BMP) signaling is thought to perform multiple functions in the regulation of skin appendage morphogenesis and the postnatal growth of hair follicles. However, definitive genetic evidence for these roles has been lacking. Here, we show that Cre-mediated mutation of the gene encoding BMP receptor 1A in the surface epithelium and its derivatives causes arrest of tooth m...
