1. In pig embryos of 100 to 270 mn the average coagulation time of the blood was found to be about 23 minutes. This represents a coagulation time six to eight times greater than that obtained for the adult. 2. The first evidence of coagulation in the blood of these embryos consisted in the appearance of small masses of fibrin deposited almost invariably at the side of the test-tube. The ensuing...

A chemical method has been devised for the quantitative determination of plasma antithrombin. A concentrate of antithrombin has been prepared from plasma. It also contains heparin cofactor activity. The two distinct activities could not be separated and may quite possibly be the properties of a single substance. When the concentrate is combined with heparin the capacity of the concentmte to des...

http://dx.doi.org/10.1016/j.jes.2015 1001-0742/© 2015 The Research C Arsenic is one of the most common inorganic contaminants in groundwater worldwide, mainly due to the release of naturally occurring arsenic from aquifer sediments (Amini et al., 2008; Li and Cai, 2015; Rahman et al., 2015). Naturally occurring arsenic exists predominantly in arsenate and arsenite species in groundwater. Arseni...

introduction cold plasma is a self-sterilized, painless, and non-contact method in surgeries. these properties allow it to be applied to the living tissues and heat-sensitive parts. the aim of this study was to design a new cold plasma producer device and evaluate the effects of cold argon plasma on decreasing the coagulation time of blood drop in vitro and that of the injured liver blood in vi...

BACKGROUND AND OBJECTIVES We seek to compare and contrast the mechanisms of blood photocoagulation under 532 and 1,064 nm laser irradiation in vitro in order to better understand the in vivo observations. We also seek to validate a finite element model (FEM) developed to study the thermodynamics of coagulation. STUDY DESIGN/MATERIALS AND METHODS We study the photocoagulation of whole blood in...

Discharging livestock manure slurry without proper treatment causes various environmental and sociological problems. Chemical coagulation is a widely used easily applicable method for treating such wastewater. However, the technique requires optimization to enhance efficiency while minimizing chemical usage. In this study, we propose an efficient, low-cost, environmentally safe solid–liquid sep...

Black carbon (BC) particles in the atmosphere have important impacts on climate. The amount of BC in the atmosphere must be carefully quantified to allow evaluation of the climate effects of this type of aerosol. In this study, we present the treatment of BC aerosol in the developmental version of the 4th generation Canadian Centre for Climate modelling and analysis (CCCma) atmospheric general ...

backgrounds and aims: methylglyoxal (mgo) is an –α, β dicarbonyl aldehyde inevitably produced from triose-phosphate intermediates of glycolysis, and amino acid. increased mgo in blood leads to alterations in coagulation, clot permeability and thus, atherosclerosis in children with diabetes; however, the precise mechanism is not clear. the present study aimed to compare different concentrations ...

In the context of multi-agent simulation of biological complex systems, we present a reaction-agent model for biological chemical kinetics that enables interaction with the simulation during the execution. In a chemical reactor with no spatial dimension -e.g. a cell-, a reaction-agent represents an autonomous chemical reaction between several reactants : it reads the concentration of reactants,...
