Birth control methods in the United States.

U.S. women have fewer birth control options than do women in other developed countries.

Breast feeding, birth spacing and their effects on child survival.

It has long been known that breast feeding inhibits female fertility and that it is a factor in restricting population growth. But just how important is it?

Cloning of nifHD from Nostoc commune UTEX 584 and of a flanking region homologous to part of the Azotobacter vinelandii nifU gene.

The heterocystous cyanobacterium Nostoc commune UTEX 584 contains two nifH-like sequences (nifH1 and nifH2) in addition to nifHD. A region of DNA 1 kilobase upstream from the 5' end of nifH showed considerable sequence similarity to part of the published nifU sequences of Azotobacter vinelandii and Klebsiella pneumoniae.

How financial barriers can frustrate good arthritis care.

Current insurance practices discriminate against the arthritis patient who does not require acute-level care. Such practices inadequately deal with the financial barriers to the procurement of the health care services that are effective in relieving pain and increasing mobility and quality of life. The result often is frustration for both the patient and the physician.

Maternal mortality in Indonesia and Egypt.

Twenty-three percent of deaths to women of reproductive age (15-49 years) in Bali, Indonesia and Menoufia, Egypt were due to maternal causes. Among the younger women, the percentage was even higher. In both areas complications of pregnancy and childbirth were a leading cause of death (the first cause in Bali, the second in Menoufia).

An evaluation of the nutrient intake of a group of elderly people attending a luncheon club.

A study was conducted to assess the nutrient intake of a group of 18 elderly men and women aged 67-85 years who attend a luncheon club in a North London Borough. Adequate intakes of most nutrients were demonstrated with the exception of zinc, although due to wide individual variation some people had intakes greatly below recommendations. The contribution of the luncheon club meal to the total diet varied widely between individuals.

Reproductive risks in a community-based distribution program of oral contraceptives, Matamoros, Mexico.

A Reproductive Risk Factors Survey was carried out in 1982 in conjunction with a community-based distribution (CBD) program in Matamoros, Mexico, to determine whether the distribution of oral contraceptives to women through CBD programs exposes any demonstrable group of users to more health risks than if the program had not been put in place. The methodology involved interviews by nurses of program pill users and non-program pill users. Health indicators related to cardiovascular accidents were the main focus of comparison between the groups.

Rare events occurring at insertion of an intrauterine device--a review of an international experience.

Events occurring at the time of insertion of an intrauterine device (IUD) are rarely studied, especially for parous women for whom, in theory, IUD contraception is most suitable. These events, although rare, cause personal distress, embarrassment and inconvenience and can have a negative impact on IUD acceptance. Sixty million women worldwide are using IUDs.

Variation in Phospholipid Ester-Linked Fatty Acids and Carotenoids of Desiccated Nostoc commune (Cyanobacteria) from Different Geographic Locations.

Profiles of phospholipid fatty acids and carotenoids in desiccated Nostoc commune (cyanobacteria) collected from China, Federal Republic of Germany, and Antarctica and in axenic cultures of the desiccation-tolerant strains N. commune UTEX 584 and Hydrocoleum strain GOEI were analyzed. The phospholipid fatty acid contents of the three samples of desiccated Nostoc species were all similar, and the dominant compounds were 16:1omega7c, 16:0, 18:2omega6, 18:3omega3, and 18:1omega7c.

Evidence of the validity of the Arthritis Impact Measurement Scales.

The Arthritis Impact Measurement Scales (AIMS) were administered to 120 patients with rheumatoid arthritis. These patients also rated the importance of various aspects of their treatment. Our findings support the validity of the pain, anxiety, depression, dexterity, and physical activity subscales of the AIMS.

Polysome turnover in immobilized cells of Nostoc commune (cyanobacteria) exposed to water stress.

Water stress induced changes in the polysome content of immobilized cells of the desiccation-tolerant cyanobacterium Nostoc commune UTEX 584. Cells maintained an intact protein synthesis complex during 2 h of drying at -99.5 MPa.

Purification and Biochemical Analysis of the Cytoplasmic Membrane from the Desiccation-Tolerant Cyanobacterium Nostoc commune UTEX 584.

The cytoplasmic membrane of the heterocystous cyanobacterium Nostoc commune UTEX 584 was isolated free of thylakoids and phycobiliprotein-membrane complexes by flotation centrifugation. Purified membranes had a buoyant density of 1.07 g cm and were bright orange.

Rapid diagnosis of Chlamydia trachomatis infection in patients attending an ophthalmic casualty department.

Direct immunofluorescence (DIF) techniques were compared with conventional cell culture for the diagnosis of ocular infections with Chlamydia trachomatis. The DIF test was found to have a sensitivity of 100% and a specificity of 97.5%.

Various health professions groups' beliefs about people with arthritis.

This study was conducted among physical therapy students, nursing students, and interns and residents to compare beliefs about people with arthritis among these groups; compare the groups' beliefs about people with arthritis to their beliefs about people with five other handicapping conditions; and explore associations of the groups' beliefs about people with arthritis with their age, sex, and personal experience with the condition. For purposes of comparison with the health professions study groups, undergraduate students in an interpersonal communications class were also surveyed. Respondents answered a ten-item questionnaire for each of the six handicapping conditions.
