TL;DR: APOE ɛ4 was associated with atrophic hippocampal volume in MRI markers, increased cerebral amyloid deposition and cerebral hypometabolism, which may indicate the potential role of the APOE gene in the pathophysiology of Alzheimer's disease.
Abstract: Objective We aimed to examine the association of apolipoprotein E (APOE) ɛ4 genotype with neuroimaging markers of Alzheimer9s disease: hippocampal volume, brain amyloid deposition and cerebral metabolism. Methods We performed a systematic review and meta-analysis of 14 cross-sectional studies identified in Pubmed from 1996 to 2014 (n=1628). The pooled standard mean difference (SMD) was used to estimate the association between APOE and hippocampal volume and amyloid deposition. Meta-analysis was performed using effect size signed differential mapping using coordinates extracted from clusters with statistically significant difference in cerebral metabolic rate for glucose between APOE ɛ4+ and ɛ4− groups. Results APOE ɛ4 carrier status was associated with atrophic hippocampal volume (pooled SMD: −0.47; 95% CI −0.82 to −0.13; p=0.007) and increased cerebral amyloid positron emission tomography tracer (pooled SMD: 0.62, 95% CI 0.27 to 0.98, p=0.0006). APOE ɛ4 was also associated with decreased cerebral metabolism, especially in right middle frontal gyrus. Conclusions APOE ɛ4 was associated with atrophic hippocampal volume in MRI markers, increased cerebral amyloid deposition and cerebral hypometabolism. Theses associations may indicate the potential role of the APOE gene in the pathophysiology of Alzheimer9s disease.

TL;DR: Results suggest that catalpol exerts its protective effect on dopaminergic neurons by inhibiting microglial activation and reducing the production of proinflammatory factors, which may possess therapeutic potential against inflammation-related neurodegenerative diseases.

TL;DR: d-limonene has antiangiogenic and proapoptotic effects on gastric cancer, thereby inhibits tumor growth and metastasis and combination of d- Limonene with cytotoxic agents may be more effective.

TL;DR: It is indicated that TNFα signaling plays some important roles in orthodontic tooth movement and real time-based reverse transcription-polymerase chain reaction analysis demonstrated increased levels of mRNA for cathepsin K.
Abstract: Orthodontic tooth movement is achieved by mechanical loading; however, the biological mechanism involved in this process is not clearly understood owing to the lack of a suitable experimental model. In the present study, we established an orthodontic tooth movement model in mice using a Ni-Ti closed coil spring that was inserted between the upper incisors and the upper first molar. Histological examination demonstrated that the orthodontic force moved the first upper molar mesially without necrosis of the periodontium during tooth movement. The number of TRAP-positive osteoclasts on the pressure side significantly increased in a time-dependent manner. Quantitative real time-based reverse transcription-polymerase chain reaction analysis demonstrated increased levels of mRNA for cathepsin K. Immunohistochemical staining revealed the expression of tumor necrosis factor-alpha (TNFalpha) in periodontium on the pressure side of the first molar during orthodontic tooth movement. When this tooth movement system was applied to TNF type 1 receptor-deficient mice and TNF type 2 receptor-deficient mice, tooth movement observed in TNF type 2 receptor-deficient mice was smaller than that in the wild-type mice and TNF type 1 receptor-deficient mice. The number of TRAP-positive osteoclasts on the pressure side was significantly small in TNF type 2 receptor-deficient mice compared with that in TNF type 1 receptor-deficient mice on day 6 after application of the appliance. The present study indicates that TNFalpha signaling plays some important roles in orthodontic tooth movement.
