BACKGROUND Chronic kidney disease (CKD) is a major risk factor for cardiovascular disease (CVD), partly due to endothelial dysfunction and chronic inflammation. Vitamin D treatment in end stage renal disease is suggested to modulate the immune system and lead to improved outcomes. We and others have demonstrated that treatment with vitamin D or activated vitamin D analogues protects the endothe...

The case here shown is the retina from an injected right eye ,taken at post mortem from a female aged 71 who had suffered from diabetes for twenty-six years. There is a Stage III diabetic retinopathy with micro-aneurysms, irregular haemorrhages, macular and punctate exudates. Although the injection is not as complete as we have obtained in freshly excised eyes, it is satisfactory for a post mor...

An important open problem in Reverse Mathematics ([16, 25]) is the reduction of the first-order strength of the base theory from IΣ1 to I∆0 + exp. The system ERNA, a version of Nonstandard Analysis based on the system I∆0 + exp, provides a partial solution to this problem. Indeed, Weak König’s lemma and many of its equivalent formulations from Reverse Mathematics can be ‘pushed down’ into ERNA,...

fab-less business model in semiconductor industry has led to serious concerns about trustworthy hardware. in untrusted foundries and manufacturing companies, submitted layout may be analyzed and reverse engineered to steal the information of a design or insert malicious trojans. understanding the netlist topology is the ultimate goal of the reverse engineering process. in this paper, we propose...

Starch, dextrin, sodium silicate (SS), and recently co-silicate (SCS) are the most known depressants for depression of iron oxides through traditional reverse flotation. However, all these depressants’ adsorption mechanisms on surface their main associated minerals (silicate phosphates) anionic flotation did not yet been thoroughly investigated. For filling this gap, as a comparative investigat...

background:in the recent decade, the reverse genetics method has been broadly used for rescue of negative-stranded rna viruses from cdna or viral minigenomes. this technique has been applied to study different steps in virus replication and virus-host interactions. reverse genetics could also be implemented for design of new vaccines. the t7 rna polymerase activity as well as virus (nucleocapsi...

synovial chondromatosis affecting the glenohumeral joint is rare. treatment primarily consists of arthroscopic loose body removal and synovectomy. shoulder arthroplasty has been mentioned in the literature as a treatment option for patients with coexisting arthritis, although the results have been underreported. the case of an 84-year-old man with long standing synovial chondromatosis of the sh...

Reverse engineering a program constructs a high-level representation suitable for various software development purposes such as documentation or reengineering. Unfortunately however, there are no established guidelines to assess the adequacy of such a representation. We propose two such criteria, completeness and accuracy, and show how they can be determined during the course of reversing the r...

waterwheels are the oldest types of hydraulic machines. these turbines are of relatively simple design, large diameter, low rotational speed and high torques. but applying them as micro hydros of high speed and small diameter is yet to be explored. a micro hydro waterwheel of one meter diameter was designed and manufactured at the iranian  esearc†h organization for science and technology (irost...
