results we performed rush on 77 patients. kappa index was 0.71 (p value = 0.000), reflecting acceptable general agreement between initial impression and final diagnosis. for hypovolemic, cardiogenic and obstructive shock, the protocol had an npv above 97% yet it had a lower ppv. for shock with distributive or mixed etiology, rush showed a ppv of 100% but it had low sensitivity. subgroup analysi...

Vertebrate central nervous system develops from a neural tube derived from the embryonic ectoderm. In mouse, the neural tube around embryonic day 10 primarily consists of neural precursor cells (NPCs). During the development of embryonic central nervous system, NPCs proliferate and migrate outward; thus later stages show NPCs toward the lumen of the neural tube and neurofilament-positive differ...

OBJECTIVES To explore whether LIF could promote the proliferation of neural precursor cells (NPCs) and to analyze the correlation between increased NPCs and FluoroGold (FG) labeled neurons in mice after spinal cord injury (SCI). METHODS Motor behavior was assessed using Rotarod and Platform Hang tests; neurons in the corticospinal and rubrospinal systems were labeled with FG, NPCs were immust...

Inflammation is part of many neurological disorders and immune reactions may influence neuronal progenitor cells (NPCs) contributing to the disease process. Our knowledge about the interplay between different cell types in brain inflammation are not fully understood. It is important to know the mechanisms and factors involved in order to enhance regeneration and brain repair. We show here that ...

Transplantation of nucleus pulposus cells (NPCs) into the intervertebral disc (IVD) has been demonstrated to be an effective treatment of degenerative disc disease (DDD). However, the underlying mechanisms have remained to be sufficiently elucidated. The aim of the present study was to explore the potential cell migration and anti‑apoptosis efficacy of NPCs in the treatment of DDD. NPCs culture...

BACKGROUND The systemic injection of neural stem/precursor cells (NPCs) provides remarkable amelioration of the clinico-pathological features of experimental autoimmune encephalomyelitis (EAE). This is dependent on the capacity of transplanted NPCs to engage concurrent mechanisms of action within specific microenvironments in vivo. Among a wide range of therapeutic actions alternative to cell r...

The Ror family receptor tyrosine kinases (RTKs), Ror1 and Ror2, have been shown to play crucial roles in developmental morphogenesis by acting as receptors or co-receptors to mediate Wnt5a-induced signaling. Although Ror1, Ror2 and Wnt5a are expressed in the developing brain, little is known about their roles in the neural development. Here we show that Ror1, Ror2 and their ligand Wnt5a are hig...

Nestin-expressing neural progenitor cells (NPCs) have been isolated from hippocampus of brains and propagated with epidermal growth factor and basic fibroblast growth factor (bFGF). However, the underlying signaling mechanisms regulating NPC proliferation remain elusive. Here we showed that neuregulinbeta1 (NRG), like bFGF, effectively promoted the proliferation of hippocampus-derived NPCs and ...

The expression of intermediate filament Nestin is necessary for the neural progenitor cells (NPCs) to maintain stemness, but the underlying cellular and molecular mechanism remains unclear. In this study, we demonstrated that Nestin is required for the self-renew of NPCs through activating MAPK and EGFR pathways. Knockdown of Nestin by shRNA inhibited cell cycle progression and proliferation in...
