The coleorhiza is a nonvascular sheath that encloses the embryonic radicle in Poaceae, and is generally the first tissue to emerge during germination. Delicate hairlike extensions develop from some coleorhiza cells prior to radicle emergence. Similar to root hairs, coleorhiza hairs are extremely sensitive to desiccation and are damaged by exposure to negative water potentials. The coleorhiza of Lolium perenne is somewhat spherical when first visible, after which a knob forms at a right angle to the caryopsis due to inner pressure from the elongating radicle. This knob increases in length until the radicle finally punctures the coleorhiza. Standard fixation procedures cause severe desiccation of coleorhiza cells and hairs, making morphological study of the coleorhiza difficult. This study was conducted to determine a more successful process for coleorhiza preservation.

Background: Suicidal behavior is a severe public health problem. Aims: To determine the rates of attempted and completed suicide among ethnic groups in The Hague, The Netherlands (2002–2004). Methods: By analyzing data on attempted and completed suicide (from the psychiatric department of general medical hospitals; the psychiatric emergency service and the municipal coroners). Results: Turkish and Surinamese females aged 15–24 years were at highest risk for attempted suicide (age-specific rate 545 / 100,000 and 421 / 100,000 person-years, respectively). Both rates were significantly higher than in the same age group of Dutch females (246 / 100,000 person-years). Turkish (2%) and Surinamese (7%) had lower repeat suicide-attempt rates than did Dutch (16%) females aged 15–24. Significantly lower suicide-attempt rates were found for Surinamese than for Dutch females aged 35–54 years. Differences were not explained by socioeconomic living conditions. The ratio fatal/nonfatal events was 4.5 times higher in males than in females and varied across age, gender, and ethnicity strata. Completed suicide was rare among migrant females. No completed suicides were observed in the Turkish and Surinamese females aged 15–24 years. Conclusions: The study demonstrates a high risk of attempted suicide and a low risk of completed suicide among young Turkish and Surinamese females.
