Micromorphological criteria of the early periods in craniocerebral trauma]

System of quantitative criteria for early periods of craniocerebral trauma involving short intervals (0-5 min, 0.5h, 1-2h, 3-4h, 5-6h) was developed on the basis of micromorphometric study of the brain obtained from 120 persons who died of craniocerebral trauma. High informative value of morphometric characteristics of vagus dorsal nucleus (values of neurocyte quantity, disorientation and deformity; percentage of cells without visible changes and different pathomorphologic types; excess coefficient; coefficient of correlation between volumes of neuron bodies and nuclei; nucleus volume) was determined. Optimal conditions of using quantitative criteria were outlined.     

Screening for barbiturates in vitreous humor by the EMIT-st serum enzyme immunoassay

In 16 medical examiner's cases, which were found to be barbiturate-positive by thin-layer chromatographic screening of the liver, blood barbiturate concentrations were determined by gas chromatography. The corresponding vitreous humor samples were screened by the enzyme multiplied immunoassay technique, the EMIT-st serum barbiturate assay. By using the recommended dilution for detecting serum barbiturates, it was possible to detect barbiturates in vitreous humor at a toxic concentration. By using one fourth the amount of diluent, the barbiturates could be detected also at a therapeutic concentration. The EMIT-st assay proved to be useful in the screening for barbiturates in vitreous humor, a material that is readily available in forensic toxicology.     

Deregistration issues in the US for foreign private issuers

The first 150 words of the full text of this article appear below. Key points

• While the passage of Sarbanes–Oxley in the USwas just one of the many causes for the lack of competitivenessof the US capital markets recently, it served to focus the attentionof foreign private issuers in the US on the difficulty and sometimesimpossibility of exiting the US capital markets.
• Unlike manyother jurisdictions, the process of deregistering in the USis distinct from process of delisting. The current rules forderegistration of foreign private issuers focus on the numberof US shareholders, regardless of how or where those shareholderspurchased their shares. In addition, foreign private issuers,were subject to complicated rules for counting US shareholders,and deregistration often would only suspend (not terminate)their reporting obligations.
• As a result of pressure from foreignprivate issuers, the SEC proposed new rules at the end of 2005to liberalize the existing deregistration regime for foreignprivate issuers. . . . [Full Text of this Article]
