Superconducting and Magnetic Behavior in La2-xNaxCuO4.

New phases of the type La2-xAx(l+)CUO4-y have been prepared where A(l+) is sodium or potassium. The sodium phases are superconducting for x values from 0.2 to 0.

Consulting dietitians in nursing homes: time in role functions and perceived problems.

A mail survey was conducted to describe Illinois consultant dietitians' perceptions of time adequacy for fulfilling role responsibilities and to identify dietary problems in nursing homes. Approximately three-fourths (74%) of the 43 respondents reported insufficient time at nursing homes, although all met or exceeded state consulting time requirements. Role functions receiving the greatest time investments were in the categories of foodservice management and nutrition care.

Optical memory disks in image data-base management for cytometry.

Many applications in image cytometry require storage and retrieval of a large number of high-resolution color video images. For this purpose, a microprocessor-controlled image cytometry database system has been developed which employs optical memory disk recording and graphics overlay capabilities. The image data base is recorded on optical disk, while associated descriptors are stored in the computer memory in a relational data base.

Older pregnant women and adolescents: nutrition data after enrollment in WIC.

Although there has been an increase in pregnancy in women over 35 years of age, the literature contains no information on dietary intakes of older pregnant women. Several studies have reported the nutritional status of pregnant adolescents who are considered to be at nutritional risk. This study investigated the energy, nutrient, and food intake patterns of 63 low-income pregnant women over 35 compared with 526 pregnant adolescents.

Dietary sodium intake of infants fed commercially prepared baby food and table food.

Sodium intake of infants varies widely with the type of food consumed. However, few reports are available describing the nutrients, including sodium values, of dietary intakes of infants receiving supplemental foods. The purpose of this study was to determine the sodium, energy, and nutrient values of diets for infants from low-income families participating in the WIC program.

Nutrition Education, Body Composition, and Dietary Intake of Female College Athletes.

In brief: This study examined the effects of nutrition education (through individual counseling) on the body composition and diet patterns of 39 female college athletes. Anthropometric and diet data were collected before and after the playing season. Ten of the athletes received individual nutrition counseling during the season and comprised group 1; the other 29 made up group 2.

Isolation and characterization of an immunosuppressive protein from Trichosanthes kirilowii root tubers.

An immunosuppressive protein was isolated from Trichosanthes kirilowii root tubers by a procedure involving acetone fractionation and ion exchange chromatography on CM-Sepharose. Homogeneity of the protein was demonstrated in immunoelectrophoresis, SDS-polyacrylamide gel electrophoresis, gel filtration, high performance liquid chromatography and a single NH2-terminal sequence. The protein had a molecular weight of 26,000, aspartic acid as the NH2-terminal amino acid and no cysteine or carbohydrates in its molecule.
