Given the paucity of the data included in the network, any additional information could have a significant impact on the results. The current results need to be interpreted with caution. We recommend updating this analysis when new evidence and treatment modalities become available. Conclusion Overall, ATV/r or ATV/cobi administered in combination with TDF/FTC appeared to lead to a decrease in eGFR from baseline ranging from -0.03 to -13.00 mL/min over 48 weeks. Such small decline is unlikely to be of clinical significance, especially in patients with a preserved renal function at baseline, but these results may shed light on the clinician decision for patients with known renal impairment or comorbid diseases affecting renal function such as diabetes mellitus, hypertension or hepatitis C virus coinfection. ATV/r combined with a non-TDF backbone led to an increase in eGFR, supporting the idea that the co-adminstration of RTV and TDF in a combination may be the factors leading to eGFR decline. Large cohorts such as the DAD suggest that unboosted ATV does not significantly impact eGFR; unfortunately it could not be assessed in this meta-analysis. 17 / 21 Meta-Analysis of Renal Function in HIV Patients Taking ATV Because individual ART drugs are not prescribed to patients in “real life”, biological experiments could be valuable to assess the renal toxicity of unboosted agents as ATV, COBI, RTV or TDF. This systematic review and meta-analysis intended to clarify the impact of various ATVcontaining regimens on renal function in patients with HIV. This study did not demonstrate evidence of decreased renal function related specifically to ATV. The clinical impact of these PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/19776696 findings remain difficult to interpret, especially with the scarcity of evidence and the short follow-up period of assessment that does not cover for the full treatment duration. Long-term data could be collected through registries and PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/19777456 inform on the risk decline of eGFR over time. When more renal safety data expressed in standard units in HIV patients become available, results from an updated meta-analysis could guide clinicians on the favourable initial ARV treatment regimen to prescribe. ~~ Alzheimer’s disease is the most common and Triptolide web refractory neurodegenerative disease and has led to a huge socioeconomic and humanistic problem. Therefore, there is an urgent need to develop novel drugs that could slow down the A aggregation-based neurodegenerative process and exert a diseasemodifying effect. The process of A aggregation can be divided into two categories, “off-pathway” and “onpathway”, but there is no fibril formation in the “off-pathway” model. In the “on-pathway” model, the entire reaction is composed of two steps, which can be directly analyzed under transmission electron microscopy: a slow nucleation step or “lag phase” and a rapid fibril elongation step. However, the experimental model of “on-pathway” A aggregation is difficult to establish within cells because of the pre-aggregates that contain -sheets . TEM can be used to exclude the pre-aggregates of A to record and confirm the de novo “on-pathway” model in a cell-free system. On-pathway A aggregation can be used as a peptide aging model to investigate the mechanisms of A fibrillogenesis and to develop inhibitors of A aggregation on the basis of the length and sometimes the diameter of the A fibrils. On the one hand, monomer nucleation may repre
