Oxyfluorfen is a phenoxyphenyl-type herbicide which is used for broad-spectrum control of broadleaf and grassy weeds. Ingestion of toxic dose of oxyfluorfen can be fatal among animals. However, toxicity to humans are rare in literature. The alterations in haem biosynthesis (anaemia) and in liver are the primary toxic effects. There are no specific antidotes and none of the current treatments have proven efficacious till date. Therefore, prevention needs to be the utmost priority, and on exposure, aggressive decontamination should be initiated. Herein, we described an oxyfluorfen toxicity with acute hepatic injury in a young woman who presented with a deliberate self-harming with an oxyfluorfen poisoning in Sri Lanka.

It is with much pleasure and gratification that I encourage you to read the messages from the presidents of the five societies for whom Microscopy and Microanalysis is the official journal. Each of the five presidents graciously agreed to write a message for this first issue of 1998. Writing such messages is often a burden on an already overtaxed schedule and we very much appreciate the effort they all have made. These contributions reflect one of the primary goals of the News and Commentary, that is, to be an arena for contributions from all of the societies affiliated with the journal—contributions of interest to a broad spectrum of microscopists. We hope to truly make this journal an endeavor reflecting international exchange and cooperation. Again, I thank these presidents for taking the time to write these words. So please, respect this effort and take the time to read their comments. The five presidential messages are presented in the order of their listing on the front cover of the journal, which reflects the order in which the particular society became affiliated with Microscopy and Microanalysis.

Mesomorphic Properties

Several new calamitic liquid-crystalline (LC) materials with flexible hydrophilic chains, namely either hydroxy groups or ethylene glycol units, or both types together, have been synthesized in order to look for new functional LC materials exhibiting both, thermotropic and lyotropic behaviour. Such materials are of high potential interest for challenging issues such as the self-organization of carbon nanotubes or various nanoparticles. Thermotropic mesomorphic properties have been studied by using polarizing optical microscopy, differential scanning calorimetry and X-ray scattering. Four of these nonchiral and chiral materials exhibit nematic and chiral nematic phases, respectively. For some molecular structures, smectic phases have also been detected. A contact sample of one of the prepared compounds with diethylene glycol clearly shows the lyotropic behaviour; namely a lamellar phase was observed. The relationship between the molecular structure and mesomorphic properties of these new LCs with hydrophilic chains is discussed.
