Investigative strategy for the forensic detection of sperm traces.

In a retrospective study, the results from 786 samples of alleged sexual assaults during a 5-year period were evaluated. Of the samples, 758 were from female victims and 28 were from male victims. The material examined during this 5-year period consisted of 561 cotton swabs with swabs taken from the genitals, mouth, anus, or skin surface.

Analysis of PIK3CA and Akt/protein kinase B in head and neck squamous cell carcinoma.

PIK3CA, which encodes the catalytic subunit, p110-alpha, of phosphatidylinositol 3-kinase (PI3K), is implicated in the development and progression of numerous neoplasias including head and neck squamous cell carcinoma (HNSCC). In the present study, we investigated the occurrence of PIK3CA hot-spot mutations in exons 9 and 20, the genomic gain and amplification of PIK3CA, the expression of PIK3CA mRNA and the p110 alpha protein, as well as the expression of phosphorylated-Akt (pAkt) in 33 cases of HNSCC and compared the results with the clinicopathological data. No non-synonymous mutations were detected.

Transcription factor (TF)-like nuclear regulator, the 250-kDa form of Homo sapiens TFIIIB", is an essential component of human TFIIIC1 activity.

The general human RNA polymerase III transcription factor (TF) IIIC1 has hitherto been ill defined with respect to the polypeptides required for reconstitution of its activity. Here we identify Homo sapiens TFIIIB" (HsBdp1) as an essential component of hTFIIIC1 and hTFIIIC1-like activities. Several forms of HsBdp1 are described.
