Selective Neuromuscular Denervation in Taiwanese Severe SMA Mouse Can Be Reversed by Morpholino Antisense Oligonucleotides.

Spinal muscular atrophy (SMA) is an autosomal recessive motor neuron disease caused by deficiency of the survival of motor neuron (SMN) protein, which leads to synaptic defects and spinal motor neuron death. Neuromuscular junction (NMJ) abnormalities have been found to be involved in SMA pathogenesis in the SMNΔ7 SMA mouse model. However, whether similar NMJ pathological findings present in another commonly used mouse model, the Taiwanese SMA mouse, has not been fully investigated.

[Cited status and its correlated factors of articles published in Chinese Journal of Pediatrics from 2001 to 2010].

Objective: The present study was designed to explore the cited status and its correlated factors of articles published in Chinese Journal of Pediatrics.

Method: Articles published in Chinese Journal of Pediatrics from 2001 to 2010 were searched using Wanfang Medical Online database, and the relationship between cited number and column and funding status were analyzed.

Results: Totally 3209 articles were published by Chinese Journal of Pediatrics from 2001 to 2010.

Morphology, crystal structure and adsorption performance of hydrothermally synthesized titania and titanate nanostructures.

Titania (TiO2) and sodium titanate nanostructures with controllable phases and morphologies were synthesized by a hydrothermal method with titanium disulfide (TiS2) as the starting material. Sodium titanate nanobelts could be synthesized under a relatively low alkaline concentration (1 mol L(-1) NaOH) and short duration (6 h). At 3 mol L(-1) HCl, rutile TiO2 nanorods were synthesized.

Magneto-optic microscope for visually detecting subsurface defects.

A visual test method for detecting microdefects under fine surfaces is described. A new MO microscope that has a laser source, a CCD camera, and an exciting coil is developed for this work. A pulse generator supplies an intermittent square pulse to the exciting coil, which can intensify eddy currents yet reduce the working temperature of the exciting coil and sample.

[Effects of nitric oxide synthase inhibitor on dentate gyrus neurogenesis after diffuse brain injury in adult rats].

Objective: To investigate the effects of selective nitric oxide synthase (NOS) inhibitors on dentate gyrus (DG) neurogenesis after diffuse brain injury (DBI) in adult rats.

Methods: DBI models were established in adult male SD rats, followed by systemic bromodeoxyuridine (BrdU) labeling of the dividing cells and immunohistochemical assay of the proliferation rates of neural precursor cells in the DG for comparison between NOS inhibitor (7-nitroindazole and Aminoguanidine) groups and the corresponding control groups at various time points after DBI.

Results: Intraperitoneal administration of 7-nitroindazole significantly reduced the number of BrdU-labeled cells in the DG of adult rats 2, 4 and 6 d after DBI (P<0.
