Dr. Joseph Chen first presented Low Endotoxin Recovery (LER) in April 2013.1 A masking effect of endotoxin was observed with a matrix containing a chelating agent and a detergent, and the endotoxin potency was not successfully recovered by dilution or magnesium replacement, the usual way to overcome the inhibition caused by chelation. The LER brought us some concerns relating to the suitability...

In the generation structure, the quark mass increases extremely rapidly with the increase of generation index, and there is the bound for generation number. The ground for this bound is investigated on the basis of a certain kind of composite model of leptons and quarks, in which they are supposed to be composed of sub-constituents with fermi statistics. Possible Chandrasekhar-like mechanism fo...

An enhancing mechanism of nuclear fusions is presented, most part of which is within the framework of the traditional theories. In this mechanism, electron currents play an important role, which are induced by an externally applied field or counterstreams of free electrons which naturally exist inside, surface and outside of bulk metals. At places of electron currents, the electric potential be...

We propose a mechanism to explain what occurs when a mixture of grains of different sizes and different shapes (i.e., different repose angles) is poured into a quasi-two-dimensional cell. Specifically, we develop a model that displays spontaneous stratification of the large and small grains in alternating layers. We find that the key requirement for stratification is a difference in the repose ...

The augmenting influence of urethan on leukemogenesis by x-radiation in mice has been found to operate when the urethan treatment follows the radiation, but not when the sequence is reversed. The result is in keeping with the idea that urethan acts as a promoting factor in leukemogenesis, as defined by the twostage mechanism hypothesis of carcinogenesis. It may also have a practical bearing on ...

DHIPC (2,4-dichloro-2´-hydroxyl-4´,6´-diisoprenyloxychalcone) is a new chalconecompound. In this study, its antidepressant-like activity of compound DHIPC was evaluated bythe forced swimming test and the tail suspension test in mice. The results showed that DHIPCsignificantly reduced the immobility time for 2 h after treatment through the oral administrationat dose of 10, 20, and 30 mg/kg in th...

The seeds of Peganum harmala L. ( Pgh ) (Zygophyllaceae) have been used in Moroccan traditional medicine for treatment of a various diseases and to relieve dolorous process. The major objective of this paper was to investigate the analgesic effect of ethyl acetate (EAE), butanolic (BE) and aqueous (AqE) extracts of seeds of Peganum harmala and elucided the possible underlying action mechani...

The present study appraised the hepatoprotective activity of aqueous extract of Camellia sinensis leaves and its possible mechanism of action against carbon-tetrachloride-induced liver damage. Liver damage was induced by   intraperitoneal administration of equal mixture of carbon tetrachloride   and olive oil (50 % v/v, 0.5 ml/kg ) in male Wistar rats (150-220g) once daily for...
