Millions of ultra-poor households in sub-Saharan Africa rely exclusively on savings groups to meet their financial needs. However, the ability of savings groups to fully meet these needs remains unclear. We randomly assign ultra-poor Ugandan households to savings groups containing different proportions of ultra-poor members. We find evidence that groups may be unable to satisfy the borrowing ne...

The release of molecules from injured tissue leads to produce inflammatory response that can result in apoptosis and cell death. Preconditioning (PC) can decrease the inflammatory response, increase neuroprotective mechanism on different levels. So, we investigated the role of PC as a suitable preventative approach in neurodegenerative disease in and inflammatory oncogenic factors in PC12 cells...

Ultra-pulsed fractional CO2 laser is an efficient, precise, and safe therapeutic intervention for skin refreshing, although accompanied with prolonged edema and erythema. In recent years, autologous platelet-rich plasma (PRP) has been proven to promote wound and soft tissue healing and collagen regeneration. To investigate whether the combination of PRP and ultra-pulsed fractional CO2 laser had...

BACKGROUND The optimal timing of salvage androgen deprivation therapy (ADT) for biochemical recurrence after radical prostatectomy is controversial. We compared the outcomes of ultra-early versus early salvage ADT. METHODS Among 855 patients undergoing radical prostatectomy at our institution between 2000 and 2012, we identified 121 with adjuvant-treatment-naïve pT2-4N0M0 prostate cancer who ...
