From ocular immune privilege to primary autoimmune diseases of the eye.

After the discovery of ocular immune privilege, exhaustive research has been performed, and advances have been made in the field of ocular immunology. Currently, it is clear that local and systemic pathways are involved in maintaining a well-preserved environment to guarantee normal vision. The development of autoimmunity in the eye is still a subject of research; however, it has been suggested that microglial cells could act as a gateway for initiating autoimmunity.

Alice in Wonderland syndrome: a novel neurological presentation of Zika virus infection.

Zika virus (ZIKV) is a flavivirus endemic in Africa and Southern Asian countries, which has recently emerged in unprecedented epidemic proportions around the world. Although ZIKV infection is often asymptomatic or distinguished by non-specific influenza-like symptoms, an increase in its pathogenicity and biological behavior has been the hallmark of the current pandemic. Increasing evidence suggests that neurotropic strains of ZIKV have evolved from less pathogenic strains of the virus.

Ocular flutter following Zika virus infection.

Zika virus (ZIKV) is an emerging flavivirus which has been linked to a number of neurologic manifestations such as Guillain-Barré syndrome (GBS), transverse myelitis, and meningo-encephalitis. Ophthalmologic manifestations are increasingly being reported; however, ocular dyskinesias have not been described in this context to date. Herein, we report a case of a 22-year-old female who presented with ocular flutter and associated Guillain-Barré syndrome following acute ZIKV infection.

Thermally induced growth of ZnO nanocrystals on mixed metal oxide surfaces.

An in situ method for the growth of ZnO nanocrystals on Zn/Al mixed metal oxide (MMO) surfaces is presented. The key to this method is the thermal treatment of Zn/Al layered double hydroxides (Zn/Al LDHs) in the presence of nitrate anions, which results in partial demixing of the LDH/MMO structure and the subsequent crystallization of ZnO crystals on the surface of the forming MMO layers. In a first experimental series, thermal treatment of Zn/Al LDHs with different fractions of nitrate and carbonate in the interlayer space was examined by thermogravimetry coupled with mass spectrometry (TG-MS) and in situ XRD.
