1. The capacity of skin constituents to participate in feather and hair morphogenesis has been analysed in chick and mouse embryos. 2. Reconstituted homoand heterospecific skin explants, consisting of epidermis and dermis from both species, were cultured for 8 days on the chorioallantoic membrane of the chick. 3. Recombinants of dorsal 11-5and 125-day mouse epidermis and dorsal 7-day or tarsome...

A convergence model of interest rates explains the evolution of the domestic short rate in connection with the European rate. The first model of this kind was proposed by Corzo and Schwartz in 2000 and its generalizations were studied later. In all these models, the European rates are modelled by a one-factor model. This, however, does not provide a satisfactory fit to the market data. A better...

1. We demonstrate the potential of extracting high-resolution dietary information from stable carbon isotopes ( δ 13 C) in horse tail-hair, in response to short-term changes in diet in controlled feeding experiments. 2. Tail hairs were sampled from six horses that had been equilibrated to C3 forage and were then subjected to a series of short-term diet switches to the C4 Coastal Bermuda Grass (...

The intermediate filament protein, nestin, marks progenitor cells of the CNS. Such CNS stem cells are selectively labeled by placing GFP under the control of the nestin regulatory sequences. During early anagen or growth phase of the hair follicle, nestin-expressing cells, marked by GFP fluorescence in nestin-GFP transgenic mice, appear in the permanent upper hair follicle immediately below the...

This exploratory study evaluated the impact of a Spanish second language (L2) domestic immersion (DI) program that was developed expediently at large university in United States response to widespread abroad (SA) closures due COVID-19. learners (n = 14) participated an intensive, six-week summer for total 96 contact hours over duration program. L2 development via conceptual replication Issa et ...

Dr. Pierre A. de Viragh, Service de dermatologie, Centre hospitaller universitaire, CH-1011 Lausanne (Switzerland) The case report of Komura and Tani [1] on a hair follicle nevus provides the opportunity to raise the question whether this hamar-toma is really an entity of its own. There are some indications that the hair follicle nevus could be a well-differentiated trichofollicu-loma cut at it...

Hair serves as a social sign of gender, age, status, values, and group membership. Hair is a major part of one's self-identity, and central to one's feeling of personal attractiveness. Treating a patient with hair loss and/or hair issues is not easy because of psychosocial overtones and patients' distress and body image concerns. In this paper, several common hair diseases will be discussed in ...
