Rational design of potent sialidase-based inhibitors of influenza virus replication

Article Abstract:

Records show evidence of influenza existing as early as 430 B.C. The fight against the virus has showed little success because of the virus's capacity to modify its surface antigens, sialidase and haemagglutinin. Two important compounds used against the virus are 4-amino and 4-guanidino-Neu5Ac2en. They influence both the in vitro and in vivo activities of the virus, both A and B. These two compounds may help in the production of effective anti-influenza drugs.

Design and synthesis of an ultraviolet-transparent nonlinear optical crystal Sr2Be2B2O7

Article Abstract:

The newly developed non-linear optical (NLO) crystal, KBe2BO3F2 (KBBF), exhibits several advantages for application to tunable ultraviolet sources which are widely used in spectroscopic applications. These laser are dependent on the frequency-doubling of lasers used. The conventional NLO materials exhibit spectral disadvantages such as less transparency in the ultraviolet region and low-level of birefringence.

The power of design

Article Abstract:

A theory has been developed that could play a role in explaining the appearance of power laws in many different areas, including economics and physics. It is suggested that power-law distributions could be the result of the design or evolution of systems for optimal behaviour.
