A Japanese region-wide survey of the knowledge, difficulties and self-reported palliative care practices among nurses.

Objective: We investigated palliative care knowledge, difficulty and self-reported practice among a region-wide sample of nurses who cared for cancer patients in Japan.

Methods: A cross-sectional questionnaire survey was distributed to 9 designated cancer centers, 17 community hospitals and 73 district nurse services across 4 regions in 2008. We used the Palliative Care Knowledge Test, the Palliative Care Difficulty Scale (five-point Likert scale) and the Palliative Care Self-Reported Practices Scale (five-point Likert scale).

Hair cycle resting phase is regulated by cyclic epithelial FGF18 signaling.

Hair follicles repeatedly cycle through growth (anagen), regression (catagen), and resting (telogen) phases. Although the signaling molecules involved in the anagen and anagen-catagen transition have been studied extensively, the signaling that controls telogen is only partly understood. Here we show that fibroblast growth factor (Fgf)18 is expressed in a hair stem cell niche throughout telogen, and that it regulates the hair cycle through the non-growth phases.

Post treatment with an FGF chimeric growth factor enhances epithelial cell proliferation to improve recovery from radiation-induced intestinal damage.

Purpose: A fibroblast growth factor (FGF) 1-FGF2 chimera (FGFC) was created previously and showed greater structural stability than FGF1. This chimera was capable of stimulating epithelial cell proliferation much more strongly than FGF1 or FGF2 even without heparin. Therefore FGFC was expected to have greater biologic activity in vivo.

An FGF1:FGF2 chimeric growth factor exhibits universal FGF receptor specificity, enhanced stability and augmented activity useful for epithelial proliferation and radioprotection.

Structural instability of wild-type fibroblast growth factor (FGF)-1 and its dependence on exogenous heparin for optimal activity diminishes its potential utility as a therapeutic agent. Here we evaluated FGFC, an FGF1:FGF2 chimeric protein, for its receptor affinity, absolute heparin-dependence, stability and potential clinical applicability. Using BaF3 transfectants overexpressing each FGF receptor (FGFR) subtype, we found that, like FGF1, FGFC activates all of the FGFR subtypes (i.

betaKlotho is required for fibroblast growth factor (FGF) 21 signaling through FGF receptor (FGFR) 1c and FGFR3c.

Fibroblast growth factor (FGF) 21, a structural relative of FGF23 that regulates phosphate homeostasis, is a regulator of insulin-independent glucose transport in adipocytes and plays a role in the regulation of body weight. It also regulates ketogenesis and adaptive responses to starvation. We report that in a reconstituted receptor activation assay system using BaF3 cells, which do not endogenously express any type of FGF receptor (FGFR) or heparan sulfate proteoglycan, FGF21 alone does not activate FGFRs and that betaKlotho is required for FGF21 to activate two specific FGFR subtypes: FGFR1c and FGFR3c.

Expression of fibroblast growth factors and their receptors during full-thickness skin wound healing in young and aged mice.

The highly ordered process of wound healing involves the coordinated regulation of cell proliferation and migration and tissue remodeling, predominantly by polypeptide growth factors. Consequently, the slowing of wound healing that occurs in the aged may be related to changes in the activity of these various regulatory factors. To gain additional insight into these issues, we quantified the absolute copy numbers of mRNAs encoding all the fibroblast growth factors (FGFs), their receptors (FGFRs) and two other growth factors in the dorsal skin of young and aged mice during the healing of full-thickness skin excisional wounds.

Comprehensive analysis of FGF and FGFR expression in skin: FGF18 is highly expressed in hair follicles and capable of inducing anagen from telogen stage hair follicles.

We quantified the mRNA expression of all 22 fibroblast growth factor family members (FGF) and their four receptors (FGFR) in adult mouse full-thickness skin at various stages of the hair growth cycle. We found that in addition to mRNA encoding FGF previously identified in skin (FGF1, 2, 5, 7, 10, 13, and 22), FGF18 mRNA was also strongly expressed. Expression of these FGF varied throughout hair growth cycle: mRNA expression of FGF18 and 13 peaked at telogen; FGF7 and 10 at anagen V; and FGF5 and 22 at anagen VI.

Bulge- and basal layer-specific expression of fibroblast growth factor-13 (FHF-2) in mouse skin.

A variety of polypeptide growth factors are involved in the dynamic maintenance of the skin and hair. Here, we demonstrate the presence of high levels of fibroblast growth factor (FGF)-13 in the bulge region of hair follicles. Using real-time PCR, we found that expression of FGF-13 mRNA is comparable to, or higher than, that of other FGF known to regulate hair growth and wound healing.
