1. An epizootic disease of ferrets with a very high case fatality rate is described. 2. By the use of suitable material the natural disease can be transmitted experimentally. 3. The primary causative agent of the disease is a filterable virus. 4. Secondary invasion by bacteria of the respiratory tract of infected animals frequently occurs. The most important secondary invader is hemolytic strep...

1 Preparatory Remarks Locke asserts that " the Ideas of primary Qualities of Bodies, are Resemblances of them, and their Patterns do really exist in the Bodies themselves; But the Ideas, produced in us by these Secondary Qualities, have no resemblance of them at all. " 1 On an unsophisticated way of taking his words, he means that ideas of primary qualities are like the qualities they represent...

background: the over-expression of recombinant proteins in large amount is important for production of therapeutic proteins and structural study. there are several systems for expression of recombinant proteins. one of the most relevant expression systems is escherichia coli (e. coli). although this organism has many advantages, most of recombinant proteins expressed in e. coli hosts form inclu...

PURPOSE The intraorbital wooden foreign body is often misdiagnosed or missed on computed tomog- raphy (CT) scan, due to the invisible or unclear images. The residual foreign bodies often occur during surgical removal. The clinical manifestations, imaging features and treatment of intraorbital wooden foreign bodies were discussed in this study. METHOD We retrospectively analyzed 14 cases of in...

We present numerical simulations of near-Earth asteroid (NEA) tidal disruption resulting in bound, mutually orbiting systems. Using a rubble pile model we have constrained the relative likelihoods for possible physical and dynamical properties of the binaries created. Overall 110,500 simulations were run, with each body consisting of ∼1000 particles. The encounter parameters of close approach d...

Synbranchus marmoratus, is a protogynic diandric species in which two types of males, primary and secondary, are found. In both types, the germinal compartment in the testes is of the unrestricted lobular type, but in secondary (sex reversed females) males the lobules develop within the former ovarian lamellae. In the present study, the germinal compartment was examined in both types of males u...
