NTAK (neural- and thymus-derived activator for ErbB kinases), also known as neuregulin-2 (NRG2), is a member of the epidermal growth factor (EGF) family, which binds directly to ErbB3 and ErbB4, and transactivates ErbB2. NTAK/NRG2 is structurally homologous to NRG1. The biological function of NTAK/NRG2 still remains unknown, especially in the nervous system, whereas NRG1 is known to be essential for nervous system function. In the present study, we examined the functions of NTAK/NRG2 secreted from astrocytes to neurons.NTAK/NRG2 was expressed in both neurons and astrocytes, as evidenced by immunohistochemical staining and RT-PCR methods. The conditioned medium (CM) from astrocytes promoted survival and neurite outgrowth of neurons. The CM stimulated phosphorylation of ErbB3 in neurons. When phosphorylation of ErbB3 was blocked by AZD8931, an ErbB3 inhibitor, neuronal survival and neurite outgrowth were reduced. Conversely, canertinib, an ErbB4 inhibitor, did not affect survival or neurite outgrowth of neurons. Survival and neurite outgrowth of neurons were lower in CM of NTAK/NRG2-knockdown astrocytes than in the CM of control astrocytes, whereas the CM of NRG1-knockdown astrocytes had little effect on survival and neurite outgrowth. The present study demonstrated that NTAK/NRG2 secreted from astrocytes bound to ErbB3 on neurons, and promoted neuronal survival and neurite extension in vitro. © 2016 Elsevier Ireland Ltd.

Studies of physician-nurse relationships have focused mainly on nurses' perceptions. Few studies have explored physicians' perceptions and related factors. This study had two aims: to describe physicians' perceptions of physician-nurse collaboration in Japan by focusing on attitudes toward collaboration and collaborative practice and to examine the effect of physicians' experiences related to collaboration on their perceptions of collaboration. A cross-sectional survey was conducted. Of the 520 physicians from four hospitals, 248 completed the survey. The survey included the Jefferson Scale of attitudes toward physician-nurse collaboration, the collaborative practice scales, learning experiences related to collaboration with nurses and experiences of joint activities with nurses. Multiple regression analysis revealed that learning experiences in undergraduate and out-of-hospital education and experiences of joint committee work were significantly associated with higher collaborative practice scores. Although participants' attitude scores had a strong association with practice scores, there were no variables significantly associated with the attitude score. This study supported the importance of education in undergraduate courses and suggested that it should be ongoing after qualification. Joint activities other than daily practice, such as continuous quality improvement, might also be effective. Factors that improve physicians' attitudes toward collaboration should be further explored. © 2013 Informa UK, Ltd.

Transplantation of somatic cells, including bone marrow stromal cells (BMSCs), bone marrow mononuclear cells (BMNCs), and choroid plexus epithelial cells (CPECs), enhances the outgrowth of regenerating axons and promotes locomotor improvements. They are not integrated into the host spinal cord, but disappear within 2-3 weeks after transplantation. Regenerating axons extend at the spinal cord lesion through the astrocyte-devoid area that is filled with connective tissue matrices. Regenerating axons have characteristics of peripheral nerves: they are associated with Schwann cells, and embedded in connective tissue matrices. It has been suggested that neurotrophic factors secreted from BMSCs and CPECs promote “intrinsic” ability of the spinal cord to regenerate. Transplanted Schwann cells survive long-term, and are integrated into the host spinal cord, serving as an effective scaffold for the outgrowth of regenerating axons in the spinal cord. The disadvantage that axons are blocked to extend through the glial scar at the border of the lesion is overcome. Schwann cells have been approved for clinical applications. Neural stem/progenitor cells (NSPCs) survive long-term, proliferate, and differentiate into glial cells and/or neurons after transplantation. No method is available at present to manipulate and control the behaviors of NPSCs to allow them to appropriately integrate into the host spinal cord. NPSP transplantation is not necessarily effective for locomotor improvement. © 2016, Neural Regeneration Research. All Rights Reserved.

Transplantation of bone marrow stromal cells (BMSCs) enhanced the outgrowth of regenerating axons and promoted locomotor improvements of rats with spinal cord injury (SCI). BMSCs did not survive long-term, disappearing from the spinal cord within 2–3 weeks after transplantation. Astrocyte-devoid areas, in which no astrocytes or oligodendrocytes were found, formed at the epicenter of the lesion. It was remarkable that numerous regenerating axons extended through such astrocyte-devoid areas. Regenerating axons were associated with Schwann cells embedded in extracellular matrices. Transplantation of choroid plexus epithelial cells (CPECs) also enhanced axonal regeneration and locomotor improvements in rats with SCI. Although CPECs disappeared from the spinal cord shortly after transplantation, an extensive outgrowth of regenerating axons occurred through astrocyte-devoid areas, as in the case of BMSC transplantation. These findings suggest that BMSCs and CPECs secret neurotrophic factors that promote tissue repair of the spinal cord, including axonal regeneration and reduced cavity formation. This means that transplantation of BMSCs and CPECs promotes “intrinsic” ability of the spinal cord to regenerate. The treatment to stimulate the intrinsic regeneration ability of the spinal cord is the safest method of clinical application for SCI. It should be emphasized that the generally anticipated long-term survival, proliferation and differentiation of transplanted cells are not necessarily desirable from the clinical point of view of safety. © 2016, Editorial Board of Neural Regeneration Research.

Purpose: To determine whether intrathecal administration of cultured autologous bone marrow stromal cells (BMSCs) is safe and feasible for treatment of subacute spinal injury. Methods: Five patients with complete tetraplegia due to cervical spinal injury on admission were included. A small amount of bone marrow was obtained during surgery for spinal fusion. BMSCs were cultured, reaching 10 7-10 8 cells. The properties and functional efficacy of the BMSCs were verified with surface marker analysis and a neurite extension test. BMSCs were administered by lumbar puncture. The patients were closely observed for 6 months, and the Committee on Effectiveness and Safety of Clinical Treatment (CESCT) evaluated safety. Results: No adverse responses were observed in biochemical and radiographic examinations. The CESCT did not recognize any harmful effects of the transplantation, and concluded it was safe for treatment. The patients were further followed up for 1 to 4 years with no adverse responses. The recovery of American Spinal Injury Association Impairment Scale (AIS) B and C patients at transplantation was rapid and remarkable, but gradual or limited in AIS A patients. Conclusion: This study demonstrated that intrathecal administration of cultured autologous BMSCs is safe and feasible for treatment of spinal cord injury. © 2012 - IOS Press and the authors.

Earlier studies have demonstrated that biosilica, synthesized by the enzyme silicatein, induces hydroxyapatite formation in osteoblast-like SaOS-2 cells. Here we study the effect of biosilica on the expressions of osteoprotegerin [. OPG] and the receptor activator for NF-κB ligand [. RANKL] in the SaOS-2 cell model. We show that during growth of SaOS-2 cells on biosiliceous matrices hydroxyapatite formation is induced, while syntheses of cartilaginous proteoglycans and sulfated glycosaminoglycans are down-regulated. Furthermore, quantitative real-time RT-PCR analysis revealed a strong time-depended increase in expression of OPG in biosilica exposed SaOS-2 cells while the steady-state expression level of RANKL remained unchanged. These results have been corroborated on the protein level by ELISA assays. Therefore, we propose that biosilica stimulated OPG synthesis in osteoblast-like cells counteracts those pathways that control RANKL expression and function (e.g. maturation of pre-osteoclasts and activation of osteoclasts). Hence, the data obtained in the present study reveal the considerable biomedical potential of biosilica for treatment and prophylaxis of osteoporotic disorders. © 2010 Elsevier Ltd.

Bio-silica represents the main mineral component of the sponge skeletal elements (siliceous spicules), while bio-polyphosphate (bio-polyP), a multifunctional polymer existing in microorganisms and animals acts, among others, as reinforcement for pores in cell membranes. These natural inorganic bio-polymers, which can be readily prepared, either by recombinant enzymes (bio-silica and bio-polyP) or chemically (polyP), are promising materials/substances for the amelioration and/or treatment of human bone diseases and dysfunctions. It has been demonstrated that bio-silica causes in vitro a differential effect on the expression of the genes OPG and RANKL, encoding two mediators that control the tuned interaction of the anabolic (osteoblasts) and catabolic (osteoclasts) pathways in human bone cells. Since bio-silica and bio-polyP also induce the expression of the key mediator BMP2 which directs the differentiation of bone-forming progenitor cells to mature osteoblasts and in parallel inhibits the function of osteoclasts, they are promising candidates for treatment of osteoporosis. © 2012 Elsevier Ltd.

A total of 82 fecal specimens which were known to be negative for rotavirus, adenovirus, norovirus, sapovirus, and astrovirus and which were collected from infants and children with acute gastroenteritis in Chiang Mai, Thailand, from January to December 2005 were screened for human parechovirus (HPeV). HPeV was detected by reverse transcription-PCR with a primer pair that amplified the 5′ untranslated region of its genome and was genotyped by sequencing of the VP1 region. HPeV was detected in 12 of 82 specimens tested, and the detection rate was found to be 14.6%. The capsid VP1 gene was successfully sequenced from nine of the HPeV strains detected. The HPeV strains studied clustered into four different genotypes, HPeV genotype 1 (HPeV1) to HPeV4, and the majority of the strains studied (five strains) belonged to HPeV1. This is the first finding of HPeV from children with acute gastroenteritis in Thailand. In addition, the diversity of the Thai HPeV strains was also noted.

Rehabilitation medicine regards pain as one disorder of whole human character and handles pain through multilateral approaches. When only the pain is treated it will not be relieved easily. Chronic pain can be more effectively handled if pain is considered as one obstacle of the whole human character and handled using many skills of rehabilitation medicine. We should apply physiotherapy including functional treatment, physical treatment and exercise from early stages of acute pain and approach chronic pain. This could improve the effectiveness of treatment for many kinds of acute pain and chronic pain disorders.
