The purpose of this study was to fabricate a conductive aligned nanofibrous substrate and evaluate its suitability and cytocompatibility with neural cells for nerve tissue engineering purposes. In order to reach these goals, we first used electrospinning to fabricate single-walled carbon-nanotube (SWCNT) incorporated poly(L-lactic acid) (PLLA) nanofibrous scaffolds and then assessed its cytocom...

Spinal cord injury is a serious threat to human health and various techniques have been deployed to ameliorate or cure its effects. Stem cells transplantation is one of the promising methods. The primary aim of the present study was to investigate the effect of the transplantation of olfactory ensheathing cell (OEC) conditioned medium‑induced bone marrow stromal cells (BMSCs) on spinal cord inj...

Olfactory bulb-derived (central) ensheathing cell (OB OEC) transplants have shown significant promise in rat models of spinal cord injury, prompting the use of lamina propria-derived (peripheral) olfactory ensheathing cells (LP OECs) in both experimental and clinical trials. Although derived from a common embryonic precursor, both sources of OECs reside in different nervous system compartments ...

The aim of this study was to investigate the level of effectiveness and initial oral English communication needs of Indonesian learners when using OEC to perform the learning activities in the business administration department of Porliteknik Negri Ujung Pandang in Makassar. Conceptually, the needs of learners cover aspect of want, lack and necessity that will be developed as the indicators of ...

The S0 → S1 transition of the oxygen-evolving complex (OEC) of photosystem II is one of the least understood steps in the Kok cycle of water splitting. We introduce a quantum mechanics/molecular mechanics (QM/MM) model of the S0 state that is consistent with extended X-ray absorption fine structure spectroscopy and X-ray diffraction data. In conjunction with the QM/MM model of the S1 state, we ...

A refined computational structural model of the oxygen-evolving complex (OEC) of photosystem II (PSII) is introduced. The model shows that the cuboidal core Mn3CaO4 with a "dangler" Mn ligated to a corner mu4-oxide ion is maximally consistent with the positioning of the amino acids around the metal cluster as characterized by XRD models and high-resolution spectroscopic data, including polarize...

Addition of non-saturating amounts of 2,3-DPG (2,3-diphosphoglycerate) within the red cell (2,3-DPG/haemoglobin less than 1) initially reduces Hill's parameter, n. With increasing 2,3-DPG/haemoglobin, n increases until a maximum is reached at 2,3-DPG/haemoglobin greater than 1. Thus, 2-3-DPG influences the shape as well as the position of the whole blood oxygen equilibrium curve (OEC). The impo...

Herein, Ca K-edge X-ray absorption spectroscopy (XAS) is developed as a means to characterize the local environment of calcium centers. The spectra for six, seven, and eight coordinate inorganic and molecular calcium complexes were analyzed and determined to be primarily influenced by the coordination environment and site symmetry at the calcium center. The experimental results are closely corr...

selon mircea eliade, le mythe raconte une histoire sacrée qui s'est passée in «illotempore»; le grand temps ou le temps primordial des commencements. vu sous cet angle, il pourrait exprimer l'origine des comportements, des rites et des croyances humains. de ce point de vue, l'infanticide constitue un exemple remarquable car il est présent dans les récits mythiques dès la naissance des premières...

Olfactory ensheathing cells (OECs) transplanted into the lesioned CNS can stimulate reportedly different degrees of regeneration, remyelination, and functional recovery, but little is known about the mechanisms OECs may use to stimulate endogenous repair. Here, we used a functional proteomic approach, isotope-coded affinity tagging and mass spectrometry, to identify active components of the OEC...
