Asynchronous Byzantine consensus algorithms are an important primitive for building Byzantine fault-tolerant systems. Algorithms for Byzantine consensus typically require at least two communication steps for decision; in many systems, this imposes a significant performance overhead. In this paper, we show that it is possible to design Byzantine fault-tolerant consensus algorithms that decide in...

Introduction: Coagulation disorders are among the diseases which afflict people and result in the death of a great number of them. Bleeding and increase of coagulation most of the time are endangers for many patients. The aim of this research was determination of PTT in urban population of Khorramabad. Materials & Methods: Through this study among 20-60 years old population living in Khorrama...

Objective Postpartum weight retention (PPWR), which refers to the value of postpartum minus pre-pregnancy weight, is a common problem among women after childbirth. The main objectives this study are understand changes in body breastfeeding mothers during long-term follow-up and preliminarily explore relationship between maternal human milk composition, including macronutri...

two deoxyglucose (dg) derivatives, (α,β)-2-deoxy-2-amino(ethylcarbamate)-d-glucose (ecb-dg) and (α,β)-2-deoxy-2-amino(1,2-dihydroxypropyl)-d-glucose (dhp-dg), were synthesized and radiolabeled successfully with [99mtc(h2o)3(co)3]+ complex. [99mtc]-ecb-dg and [99mtc]-dhp-dg complexes were prepared (96% and 93% radiochemical purities respectively) by using 46 mci of na99mtco4 in 1 ml saline. radi...

Adenosine diphosphate (ADP) induced aggregation of rabbit platelets, without the release reaction, causes a significant decrease (7%) in the amount of phosphatidylinositol-4,5-bisphosphate (PIP2) at 10 sec and at 60 sec (11%). In platelets prelabeled with 32P-phosphate, this decrease in PIP2 is associated with a decrease in PIP2 radioactivity, which is significant at 50 sec. The decrease in PIP...

The effects of Tween-20 and Zn(II) on ethylbenzene removal were evaluated using two biotrickling filters (BTFs), BTF1 and BTF2. Only BTF1 was fed with Tween-20 and Zn(II). Results show that ethylbenzene removal decreased from 94% to 69% for BTF1 and from 74% to 54% for BTF2 with increased organic loading from 64.8 to 189.0 g ethylbenzene/(m³·hr) at EBRT of 40 sec. The effect of EBRT (60-15 sec)...

Compounds with dual action on cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) may be a treatment option for erectile dysfunction, as they not only promote penile erection but also prevent the upregulation of phosphodiesterase-5. In this study, we examined the possible relaxant effect and mechanism of 17-nor-subincanadine E (SEC, 0.2-200 µmol l⁻¹), a plant-derived...

Antimicrobial proteins are a rich source of new lead compounds for the development of new drugs that will tackle global resistance towards existing antibiotics. Caenopore-5 (Cp-5) is an antimicrobial protein (AMP) expressed in the intestine of the nematode Caenorhabditis elegans and is a member of the lipid binding saposin-like-protein family, composed of 5 a-helices and 3 disulfide bonds. Subs...
