Introduction In major reviews of amyloidosis (Glenner, Terry and Isersky, 1973; Stirling, 1975) psoriasis is not listed as one of the predisposing causes nor is it mentioned as an aetiological factor in renal amyloidosis (Heptinstall, 1974). Case reports have drawn attention to amyloidosis in patients with pustular psoriasis (Berger, 1969; Mackie and Burton, 1974) and psoriatic arthritis (Reed ...

The stochastic differential equations for a model of dissipative particle dynamics, with both total energy and total momentum conservation at every time-step, are presented. The algorithm satisfies detailed balance as well as the fluctuation-dissipation theorems that ensure that the proper thermodynamic equilibrium can be reached. Macroscopic equilibrium probability distributions as well as equ...

–This article discusses common problems in undergraduate college mathematics courses. One main problem is the students’ retention of knowledge. The problem can be attributed to the learning pattern adopted by the students. Some students strive to attain a deeper level of learning while others often memorize the formulas and seldom make connections to different aspects of the subjects (Ausubel, ...

The concept of a single conducting system in coelenterates, represented by 'the nerve net', is being replaced by the realization that there are often multiple conducting systems co-existing in the same tissue. Romanes, in 1877, demonstrated two kinds of conduction in the bell of the jellyfish Aurelia which were distinguished by having different thresholds, conduction velocities, and behavioural...

Saul Kripke (1980, 112–4) has claimed that there are necessary connections between material things and their material origins. His presentation of such necessity of origin theses included two paradigmatic examples: that it is impossible for a particular table to have been constructed from any hunk of matter other than that from which it was actually constructed, or for a particular human being ...

The potent heat-labile bactericidal property of fresh mammalian defibrinated blood or serum in vitro has been known since the studies of Nuttall (1) and Buchner (2) over 70 years ago. By 1928, it had been shown that serum components very like those of complement were necessary for this action (3). Although a number of investigators in the fields of bacteriology and immunology have interested th...

The electoral cycle has become an established feature of voting behaviour, both in Britain and in other European countries. After an initial `honeymoon' between the new Government and the electorate, disillusion often sets in and Government popularityÐwhether measured by opinion polls, by-elections or mid-term elections such as the European and local electionsÐ tends to decline. In most cases, ...
