چکیده
The epidermis is an integral part of our largest organ, the skin, and protects us against the hostile environment. It is a highly dynamic tissue that, during normal steady-state conditions, undergoes constant turnover. Multiple stem cell populations residing in autonomously maintained compartments facilitate this task. In this Review, we discuss stem cell behaviour during normal tissue homeostasis, regeneration and disease within the pilosebaceous unit, an integral structure of the epidermis that is responsible for hair growth and lubrication of the epithelium. We provide an up-to-date view of the pilosebaceous unit, encompassing the heterogeneity and plasticity of multiple discrete stem cell populations that are strongly influenced by external cues to maintain their identity and

Enhanced inhibitory synaptic transmission in the spinal dorsal horn mediates antinociceptive effects of TC-2559
BACKGROUND TC-2559 is a selective α4β2 subtype of nicotinic acetylcholine receptor (nAChR) partial agonist and α4β2 nAChR activation has been related to antinociception. The aim of this study is to investigate the analgesic effect of TC-2559 and its underlying spinal mechanisms. RESULTS 1) In vivo bioavailability study: TC-2559 (3 mg/kg) had high absorption rate in rats with maximal total bra...
متن کاملOn the limit of large girth graph sequences
Let d ≥ 2 be given and let μ be an involution-invariant probability measure on the space of trees T ∈ Td with maximum degrees at most d. Then μ arises as the local limit of some sequence {Gn} ∞ n=1 of graphs with all degrees at most d. This answers Question 6.8 of Bollobás and Riordan [4].
متن کاملParking Sensing and Information System: Sensors, Deployment, and Evaluation
This paper describes a smart parking sensing and information system that disseminates the parking availability information for public users in a cost-effective and efficient manner. The hardware framework of the system is built on advanced wireless sensor networks and cloud service over the Internet, and the system is highly scalable. The parking information provided to the users is set in the ...
متن کامل0 A Phenomenological Model of the Baryons The Body Center Cubic Model of the Vacuum Material
From the quark confinement idea, we conjecture that the quarks compose colorless particles (uud and udd the Lee Particles) and then the Lee Particles construct a body center cubic lattice in the vacuum. In terms of the energy band theory, from the symmetries of the body center cubic periodic field, we deduce the baryon spectrum (with a united mass formula) using only 2 flavored quarks u and d. ...
متن کاملCCR 20th Anniversary Commentary: Paving the Way for Circulating Tumor Cells.
Cancer cells can enter the bloodstream, form distant metastases, and ultimately lead to death. A study by Allard and colleagues, which was published in the October 15, 2004, issue of Clinical Cancer Research, concluded that the CellSearch system could be used as a reliable tool to investigate circulating tumor cells and their clinical utility, and it spurred a still-growing interest in the field.
