Infectious uveitis accounts for majority of the cases of uveitis in developing countries. It also encompasses an array of various microorganisms and their clinical presentations. Some of these infectious uveitic entities are familiar, while others are newly emerging in the global ophthalmic world. Many of these entities are also a major cause of morbidity and mortality, and appropriate, timely ...
Staurolite has been long considered an enigma because of its remarkable pseudosymmetry and the frequent twinning. Staurolite gives two twins whose occurrence frequency seems to contradict the condition of lattice restoration requested by the reticular theory of twinning, in that the more frequent one (Saint Andrews cross twin) has a twin index of 12, whereas the less frequent one (Greek cross t...
A report that a switch of a yeast protein to a 'prion' state triggers diverse phenotypic changes has prompted re-examination of the processes of evolution. To what extent should processes of gene expression and control be interpreted in terms of their capacity to allow future evolution as well as present adaptation?
The last thing William Shakespeare wants to be is predictable. Roughly halfway through his published collection of one hundred and fifty-four sonnets, he frets that we may find it dull that he “write[s] . . . all one, ever the same,” producing one fourteen-line poem after another (76.5). He has reason to worry: he rarely allows himself to deviate from a strict iambic pentameter, and holds his v...
Craving is considered to play an important role in the persistence of drug use and relapse of drug use. Very few studies have looked into the subjective experience of this phenomena. This study attempts to study craving comprehensively as described by the subjects. In the present study 30 patients of heroin dependence syndrome were assessed (using a semi-structured questionnaire) for the subjec...
Ena/VASP proteins are actin-binding proteins that localize to actin stress fibres, the tips of filopodia and the lamellipodial leading edge. In the past few years, a number of seemingly conflicting studies have confused the Ena/VASP field, pointing to roles for these proteins in both promotion and inhibition of actin-dependent processes. Recent discoveries resolve these contradictions and sugge...

This research note suggests a new way to realize a high speed direct encryption based on quantum detection theory. The conventional cipher is designed by a mathematical algorithm and its security is evaluated by the complexity of the algorithm for cryptanalysis and ability of computers. This kind of cipher cannot exceed the Shannon limit of cryptography, and it can be decrypted with probability...
By the application of a linear mass spectrum to a composite system of both the pseudoscalar and scalar meson nonets, we find three relations for the masses of the scalar states which suggest the qq̄ assignment for the scalar meson nonet: a0(1320), K ∗ 0 (1430), f0(1500) and f ′ 0(980).
