BACKGROUND Recombinant human-erythropoietin (rh-EPO) has therapeutic efficacy for premature infants with brain damage during the active rehabilitation and anti-inflammation. In the present study, we found that the rh-EPO was related to the promotion of neovascularization. Our aim was to investigate whether rh-EPO augments neovascularization in the neonatal rat model of premature brain damage th...

We develop a 2D slip-weakening description of a self-healing slip pulse that propagates dynamically in a steady-state configuration. The model is used to estimate patterns of off-fault secondary failure induced by the rupture, and also to infer fracture energies G for large earthquakes. This extends an analysis for a semiinfinite rupture (Poliakov et al., 2002) to the case of a finite slipping ...

PURPOSE To study healing of retinal laser lesions in patients undergoing PRP using SD-OCT. METHODS Moderate, light and barely visible retinal burns were produced in patients with proliferative diabetic retinopathy scheduled for PRP using 100-, 20- and 10-ms pulses of 532-nm laser, with retinal spot sizes of 100, 200 and 400 μm. Lesions were measured with OCT at 1 hr, 1 week, 1, 2, 4, 6, 9 and...

PURPOSE A range of P2Y and P2X receptors is expressed in the rat lens. Because most P2X receptors are located in the cytoplasm, the authors sought to determine whether P2X receptors are functionally active. METHODS Rat lenses were cultured under either isotonic or hypertonic conditions in the presence of P2 receptor agonists or antagonists. Lenses were fixed and cryosectioned, cell membranes ...

Existing plant types of rubber tree after planting and available tapping tree were investigated, and there were about 28 rubber plantations with different tapping years of 8 varieties “CATAS7-33-97”, “CATAS8-79”, “CATAS7-20-59”, “PR107”, “RRIM600”, “GT1”, “INA873”, “93-114” in South China. The results showed that there were six kinds of existing plant types of rubber tree after planting of rubb...

The moderate magnitude Chamoli earthquake, which occurred on 29 March, 1999 in the Alkananda river valley region of Garhwal Himalaya, caused considerable loss to human life and property. From a systematic ®eld survey of the damage, conducted for ®ve continuous days immediately after the earthquake, the following could be noted: (i) The consequences of the damage are most pronounced near the Mai...

BACKGROUND AND OBJECTIVES This investigation determined incision characteristics and soft-tissue damage resulting from standardized incisions using a wide range of laser modes and parameters of a diode laser at 810 nm. STUDY DESIGN/MATERIALS AND METHODS Histologic examinations were performed to verify vertical and horizontal tissue damage as well as incision depth and width. RESULTS Incisio...

background economic consequence analysis is vital for recognizing pipeline comprehensive risk analysis and emergency response planning. objectives the purpose of this study was to estimate economic loss due to fire and explosion in petrochemical feed and product pipelines. materials and methods the present study which performed on 47 pipelines of a petrochemical special zone, pertinent pipeline...

A series of large scale dynamic tests were conducted at the LKAB Kiirunavaara mine using explosives to generate the dynamic load on the support system. This was done with the aim of developing a testing methodology for in-situ testing of ground support. Furthermore, the response of the installed rock support system to strong dynamic loading was evaluated. The results of the Tests 1, 2, 3, 4 and...
