In mammalian peripheral nerves, unmyelinated C-fibers usually outnumber myelinated A-fibers. By using transmission electron microscopy, we recently showed that the saphenous nerve of the naked mole-rat (Heterocephalus glaber) has a C-fiber deficit manifested as a substantially lower C:A-fiber ratio compared with other mammals. Here we determined the uniqueness of this C-fiber deficit by perform...

Abstract In this research, the hybrid natural fiber composite specimens were fabricated with a 64 wt% epoxy resin matrix, 20 coir fiber, and 16 of various fibers by hand-layup method. The influences (Coir, Jute, Flax, Cotton, Human Hair, Sisal, Kenaf, Calotropis) on mechanical characteristics (tensile, flexural, impact strengths) drilling properties (delamination factor ovality) Coir-fiber base...

Previous work has implicated the Myc-binding transcription factor Miz1 in the control of keratinocyte proliferation and in the cellular response to TGFbeta. Miz1 is expressed in basal keratinocytes of the interfollicular epidermis and in hair follicles. Here we have conditionally knocked out the POZ/BTB transactivation domain of Miz1 in keratinocytes using a keratin 14 (K14)-Cre mouse deleter s...

In this study a new method of preconcentration, separation and efficient measuring of so-called hollow fiber solid / liquid phase microextraction has been introduced for the determination of trace amounts of lorazepam (LRZ) in water samples, urine and hair using differential pulse voltammetry. To this end, a hybrid adsorbent material was used that involved ionic liquid assisted magnetic multi-w...

Hair is a potent cultural signal that when perceived as deficient can invite psychological trauma. Over the past few decades, researchers have successfully dissected several controls for hair follicle development and growth. However, we know relatively little about the genetic controls for hair fiber form and texture, despite wide variability in the expression of hair phenotypes among different...

Human hair consists of proteins, lipids, water, trace elements and pigments. The composition of the first four of these components is the focus of this Chapter. About two decades ago the emphasis on the proteins of hair was on its amino acid constituents which provided important information on the relative amounts of different functional groups in different types of hair and in different region...
