LncRNA TUG1 positively regulates osteoclast differentiation by targeting v-maf musculoaponeurotic fibrosarcoma oncogene homolog B.

Osteoclast differentiation-mediates bone resorption is the key biological basis of orthodontic treatment while the specific mechanism of osteoclastogenesis remains unclear. This study aims to explore the underlying mechanism of the osteoclast differentiation from the perspective of long non-coding RNA (LncRNA). In the present study, the osteoclast differentiation of CD14 peripheral blood mononuclear cells (PBMCs) was induced by recombinant human macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor κB ligand (RANKL), and LncRNA TUG1 expression was dramatically elevated during this process.

Effects of the transcription factor Olig1 on the differentiation and remyelination of oligodendrocyte precursor cells after focal cerebral ischemia in rats.

The differentiation and maturation of oligodendrocyte precursor cells (OPCs) is important for remyelination in the central nervous system. Nevertheless, this process is often limited and incomplete in ischemic injury. Oligodendrocyte transcription factor 1 (Olig1) is important for the maturation of OPCs and the repair of demyelinated lesions.

Study Selection: We included data from peer-reviewed journals on impacts of DBS on neuropsychological profiles, sensory function, autonomic symptoms, weight changes, and sleep disturbances.

Transient bullous dermolysis of the newborn: a novel de novo mutation in the COL7A1 gene.

Background: Bullous dermolysis of the newborn (BDN), an extremely rare clinical type of dystrophic epidermolysis bullosa (DEB), is characterized by subepidermal blistering at birth or shortly thereafter, followed by rapid improvement with minimal scarring or pigmentation. A total of 38 cases have been reported in the literature since the disease was initially described in 1985, but only 14 mutations in COL7A1, the gene responsible for the disease, have been detected in families with BDN.

Objectives: We report a Chinese male infant with BDN and indirect inguinal hernia, in whom a novel de novo mutation in COL7A1 was demonstrated.

Infarction of the corpus callosum: a retrospective clinical investigation.

Objectives: The aim of this study was to investigate patients with ischemic infarctions in the territory of the corpus callosum to advance our understanding of this rare stroke subtype by providing comprehensive descriptive and epidemiological data.

Methods: From January 1, 2010 to June 30, 2014, all cases of acute ischemic stroke diagnosed by clinical manifestation and diffusion weighted imaging in Dalian Municipal Central Hospital were investigated. The patients presenting with corpus callosum infarctions were selected and further allocated into genu and/or body and splenium infarction groups.

Therapeutic effect of mesenchymal stem cells in rats with intracerebral hemorrhage: reduced apoptosis and enhanced neuroprotection.

Stem cell transplantation has been used to improve neural function in intracerebral hemorrhage (ICH). However, reports on bone marrow-derived mesenchymal stem cell (MSC) transplantation in ICH are limited. We aimed to explore the therapeutic effect and related mechanisms by transplantation of MSCs in rats with ICH.

Different mechanisms of extinction of conditioned taste aversion are dependent on time intervals of extinction following conditioning.

After extinction, the reappearance of a conditioned response induced by an unconditioned stimulus which is weaker than that used during the conditioning training indicates that the extinction procedure does not eliminate the original conditioned memory. Recent studies on fear conditioning have shown that rats exhibited little or no recovery of conditioned responding if the time interval between fear acquisition and extinction was short, suggesting that the extinction process may erase the original conditioning trace in this situation. In the present study, a saving experiment was conducted in rats to investigate whether an aversive response could be recovered following extinction training with different time intervals after acquisition of conditioned taste aversion (CTA).

[Study on depression in 212 patients with viral hepatitis].

Objective: To investigate the symptoms on depression in patients with viral hepatitis.

Methods: A cross-sectional study was conducted among the patients with viral hepatitis in infectious diseases Hospital of Taiyuan.

Brief spatial experiences increase granule cell survival in the dentate gyrus of adult rats.

Rats of two experimental groups were placed in an open-field apparatus for 3-5 spatial exploration, each placement lasting 5min (total duration of 15-25min), and had a significantly greater newborn-neuron survival rate of the granule cells than the control group by evaluating the density of 5-bromo-2'deoxyuridine positive cells in the dentate gyrus. This study suggests that brief spatial experiences are sufficient to enhance the survival rate of newborn neurons.
