The Cloning and Characterization of Two ROP/RAC G-Proteins from Gossypium Hirsutum
Rop/Rac proteins are plant-specific monomeric guanosine triphosphate-binding proteins (G-proteins) with important functions in plant development. Until recently, only three cotton (Gossypium hirsutum) Rop/Rac G-protein genes were sequenced, representing subfamilies III and IV of the plant monomeric …

Functional analysis of novel protein-protein interactions involving ROP GTPases in Arabidopsis thaliana and Populus trichocarpa
… in Populus and Arabidopsis. Members of the ROP GTPase family, PB15 in poplar and ROP11 in Arabidopsis, interact with the domain of unknown function (DUF) 620 (DUF620) proteins (e.g., PB129 in poplar). Ectopic co-expression of PB15 and PB129 in Arabidopsis caused outgrowths at the base of …

Retinopathy of Prematurity in a cohort of neonates at Groote Schuur Hospital
… Screening for Retinopathy of Prematurity (ROP) is recommended to prevent possible blindness. Prior to 2016, resource limitations precluded routine ROP screening at Groote Schuur Hospital (GSH). Previous pilot studies at GSH did not detect ROP requiring treatment. However, improved survival …

Retinopathy of prematurity screening criteria and work load implications at Tygerberg Children's Hospital, South Africa: A cross-sectional study
High-income country ROP Screening guidelines are not appropriate for middle-income countries and screening requirements may vary even between units within one city. This study aimed to determine optimal ROP screening criteria, and its workload implications, for Tygerberg Children's Hospital (TCH), …

Analytical Modeling and Diagnosis of Penetration Rate Performance of PDC Bits
… ft) wells, due to slow rate of penetration (ROP) at depth, has severely limited the utilization and economic significance of deep hydrocarbon resources. The overall objective of this study was to obtain a better understanding of the major cause(s) of slow ROP in deep drilling. An analysis of …

Indium complexes and their role in the ring-opening polymerization of lactide
… sodium ethoxide. The complex 3 is active for the ROP of β-butyrolactone ε-caprolactone and lactide and is the first reported indium-based catalyst for lactide or β-butyrolactone ROP. Kinetic studies of 3 for ROP of LA revealed that catalyst was well-behaved, and that the rate was first order with …

A multi-objective, decomposition-based algorithm design methodology and its application to runaway operations planning
… a heuristic decomposed algorithm for solving the ROP problem. This decomposition methodology offers an original paradigm potentially applicable to the design of solution algorithms for a class of problems with functions and parameters that, similar to those of the ROP problem, can be parsed in …

Development of Controlled Ring-Opening Polymerization of O-Carboxyanhydrides
… the development of ring-opening polymerization (ROP) of O-carboxyanhydrides (OCAs) to synthesize functionalized, degradable polyesters. Biodegradable polyesters are promising alternatives to conventional petroleum-based non-degradable polyolefins and they are widely used in everyday applications …

Refractive Outcome in Eyes of Preterm Infants
… two groups according to treatment for threshold ROP (retinopathy of premature); group 1: children born prematurely with threshold ROP, group 2: children born prematurely without threshold ROP. Cycloplegic refraction was performed, and ultrasound biometry (A-scan) was also performed. These results …

Record and replay based virtual-machine introspection for system security
… attacks like Return Oriented Programming (ROP) requires frequent and expensive checks. Complete security defenses have been proposed yet modern systems are still vulnerable to ROP attacks. We provide complete security by decomposing the solution into two stages. The first stage raises …

Current therapeutic approaches for retinopathy of prematurity
Η αμφιβληστροειδοπάθεια της προωρότητας (ROP) παραμένει μια σημαντική αιτία αποτρέψιμης παιδικής τύφλωσης και έχει γίνει ολοένα και πιο συχνή καθώς η επιβίωση των εξαιρετικά πρόωρων νεογνών βελτιώνεται παγκοσμίως. Η ROP προκύπτει από μια διφασική διαταραχή της φυσιολογικής αγγειακής ανάπτυξης του …
