Immunophenotypic Variations in Mantle Cell Lymphoma and Their Impact on Clinical Behavior and Outcome.

Context.—: Immunophenotypic variations in mantle cell lymphoma (MCL) from the classic CD5/CD10/CD23/FMC-7 immunophenotype have been reported in the literature, but correlation with clinical behavior and outcome has not been fully studied.

Objective.

Release of lead from bone in pregnancy and lactation.

Concentrations and isotope ratios of lead in blood, urine, 24-h duplicate diets, and hand wipes were measured for 12 women from the second trimester of pregnancy until at least 8 months after delivery. Six bottle fed and six breast fed their infants. One bottle feeder fell pregnant for a second time, as did a breast feeder, and each was followed semicontinuously for totals of 44 and 54 months, respectively.

Acquisition and retention of lead by young children.

The concentrations and isotope ratios of lead in blood and urine, on the hands, and in duplicate diet samples were measured for children living in Omaha, Nebraska. One group consisted of 22 children followed from birth to between 1 and 2 years of age and another group was 20 2- to 4-year-old children followed for 1 year, although some in each group were followed for periods between 3 and 4 years. At no time in life was a component of dietary lead identified in blood by isotope ratios, and blood lead appears dominated by lead derived from the hands, which in turn appears derived from the floors.

The age of the carbonates in martian meteorite ALH84001.

The age of secondary carbonate mineralization in the martian meteorite ALH84001 was determined to be 3.90 +/- 0.04 billion years by rubidium-strontium (Rb-Sr) dating and 4.

Asteroidal water within fluid inclusion-bearing halite in an H5 chondrite, Monahans (1998).

Crystals of halite and sylvite within the Monahans (1998) H5 chondrite contain aqueous fluid inclusions. The fluids are dominantly sodium chloride-potassium chloride brines, but they also contain divalent cations such as iron, magnesium, or calcium. Two possible origins for the brines are indigenous fluids flowing within the asteroid and exogenous fluids delivered into the asteroid surface from a salt-containing icy object.

Use of a bogus pipeline method to increase accuracy of self-reported alcohol consumption among pregnant women.

Pregnant women (N = 220) attending urban maternity care clinics were randomly assigned to study groups to determine the effectiveness of a "bogus pipeline" method to increase the accuracy of behavioral self-reports of alcohol consumption. Results indicate a significant difference (p less than .025) between those who reported alcohol consumption and those who were told their behavioral self-report of alcohol consumption would be confirmed by a physiological test (bogus pipeline).

The effectiveness of smoking cessation methods for smokers in public health maternity clinics: a randomized trial.

Little insight is available in the literature on how best to assist the pregnant smoker in public health maternity clinics to quit during pregnancy. A randomized pretest/posttest experiment was used to evaluate the effectiveness of two different self-help cessation methods. Three hundred and nine pregnant women from three public health maternity clinics were assigned randomly to one of three groups with one-third assigned to each: a control group; a group receiving the American Lung Association's Freedom From Smoking Manual; and those receiving A Pregnant Woman's Self-Help Guide to Quit Smoking.
