In this study, we describe an efficient protocol for the formation of in vitro developed pronuclei for micromanipulation techniques. Our approach involved incubation of demembranated or permeabilized mammalian sperm in a phosphate buffer supplemented with heparin and beta-mercaptoethanol. Under the prevailing conditions, we achieved a uniform and reliable(More)
By hybridizing colonies grown from 928 individual stool samples of patients suffering from diarrhea with oligonucleotide probes 772 and 849 complementary to Shiga-like toxin I (SLT-I) and SLT-II gene sequences, respectively, we identified two strains that hybridized with probe 849, which biochemical identification revealed as Citrobacter freundii. An(More)
During the past decade, multi-touch surfaces have emerged as valuable tools for collaboration, display, interaction, and musical expression. Unfortunately, they tend to be costly and often suffer from two drawbacks for music performance: (1) relatively high latency owing to their sensing mechanism , and (2) lack of haptic feedback. We analyze the la-tency(More)
Immunofluorescence staining was used to study the precise subcellular distribution of the nuclear matrix antigen, mitotin, in mouse cells characterized by either a mitotic or an endomitotic organization of the cell cycle. In mitotically dividing cells, mitotin showed a speckled distribution within interphase nuclei. In addition, some interphase cells(More)
