Intervertebral disc degeneration, a major cause of chronic low back pain, is caused by irreversible changes inthe nucleus pulposus cells that make up part the disc. In recent years, regenerative medicine for intervertebraldisc degeneration through administration mesenchymal stem (MSCs) and cytokines has been performed. Dedifferentiated fat (DFAT) are MSC-like multipotent can be prepared ceiling...

The antibacterial activity of the root, stem and leaf extracts of Excoecaria agallocha L. was tested against the test organisms Bacillus subtilis, Escherichia coli, Klebsiella pneumoniae, Salmonella spp., Shigella sonnei and Staphylococcus aureus. The activity was tested both by agar well diffusion and disc diffusion methods. It was found that the extracts were very effective in controlling the...

Five new and six known species belonging to the genus Basirotyleptus collected from Western Ghats, India, are described illustrated. conicaudatus sp. nov. is characterized by having 0.42–0.44 mm long body; odontostyle 9.5–10.0 μm, odontophore 11.5–12.0 μm; pharyngeal bulb pear-shaped, 14–15% of total neck length; female genital system mono-opisthodelphic; tail conoid with acute terminus. constr...

The surfaces of annulus fibrosus tears are known harbingers of inflammatory constituents within intervertebral discs, stimulating sensitized nocioceptors within those tears. Other current treatment options of internal disc disruption neglect to specifically address the surface of these tears. Therefore, this investigation answers the question: does nonautologous fibrin sealant applied to the su...

Adult neurogenesis research in mammals presents a challenge as most stem cells and progenitors are located deep in opaque brain tissues. Here, we describe an efficient ferritin-based magnetic resonance imaging (MRI) reporter and its use to label mouse subventricular zone progenitors, enabling in vivo visualization of endogenous neuroblast migration toward the olfactory bulb. We quantify the eff...

Adult neural stem/progenitor (B1) cells within the walls of the lateral ventricles generate different types of neurons for the olfactory bulb (OB). The location of B1 cells determines the types of OB neurons they generate. Here we show that the majority of mouse B1 cell precursors are produced between embryonic days (E) 13.5 and 15.5 and remain largely quiescent until they become reactivated po...

Understanding the biology of adult neural stem cells has important implications for nervous system development and may contribute to our understanding of neurodegenerative disorders and their treatment. We have characterized the process of olfactory neurogenesis in adult mice lacking inhibitor of DNA binding 2(-/-) (Id2(-/-)). We found a diminished olfactory bulb containing reduced numbers of g...

New neurons are continuously generated from neural stem cells with astrocyte properties, which reside in close proximity to the ventricle in the postnatal and adult brain. In this study we found that microRNA-124 (miR-124) dictates postnatal neurogenesis in the mouse subventricular zone. Using a transgenic reporter mouse we show that miR-124 expression is initiated in the rapid amplifying proge...

In the present study, we demonstrated that insulin is produced not only in the mammalian pancreas but also in adult neuronal cells derived from the hippocampus and olfactory bulb (OB). Paracrine Wnt3 plays an essential role in promoting the active expression of insulin in both hippocampal and OB-derived neural stem cells. Our analysis indicated that the balance between Wnt3, which triggers the ...

Genomic imprinting is implicated in the control of gene dosage in neurogenic niches. Here we address the importance of Igf2 imprinting for murine adult neurogenesis in the subventricular zone (SVZ) and in the subgranular zone (SGZ) of the hippocampus in vivo. In the SVZ, paracrine IGF2 is a cerebrospinal fluid and endothelial-derived neurogenic factor requiring biallelic expression, with mutant...
