Inheritance of sterility in mutants of soybeans

In the summer of 1978 crosses were made between maintainer lines of ms1 and ms2 and a soybean mutant of D68-127 segregating for sterility. D68-127 originated from the cross Dyer/Bragg. Sterile mutants of D68-127 resulted from treatment of seed with the mutagenic agents diethyl sulfate and fission neutrons. F1 plants were grown in the greenhouse during the winter of 1978-79 and F2 populations were grown in the field during the summer of 1979. Near maturity, all plants were classified on the basis of phenotype as being fertile or sterile. The objective of this study was to test the hypothesis that the sterility mutant of D68-127 is a male-sterile mutant conditioned by a single gene, either ms1 or ms2. Based on the results obtained it appears that the gene involved in the sterility of D68-127 is a single recessive gene and that it is male-sterile. The F2 segregation data best support ms1 as being the gene involved in the sterility of D68-127. However, the possibility of ms2 or other ms genes could not be ruled out. Sterile plants, or those remaining green at maturity, of ms1, ms2 and D68-127 mutant produced variable amounts of viable pollen which resulted in seed production in many instances indicating that none of the genes provided complete male-sterility

Rising to the Challenge: Nursing Leadership via Nurse-Led Service Provision for Chronic Disease Management and Prevention

All nations are currently challenged by the increasing prevalence of non-communicable and chronic disease [1]. In Australia, by 2051, over 50% of the population over 50 will have a chronic disease [2]. In addition to increased levels of chronic disease, services will be stretched through workforce shortages, and government policies to provide greater access to services. Within the United States of America demand for primary care services will further increased by the passage and progressive implementation of the Affordable Care Act (ACA), which expands Medicaid coverage to millions of low-income Americans [3]. Given the increasing levels of disease burden, all staff, not just doctors, need to be viewed as part of the solution and encouraged to innovate and search for better and more affordable ways of delivering effective and appropriate care [4]. Globally, nurses are the largest and most accessible cohort within the health workforce. It is not surprising; therefore, that increasing reference to nurse-led services is present within the literature. This paper reports the findings of a focused literature review aimed at identifying the range of leadership skills and attributes required of nurses involved in the leading roles in the provision of nurse-led services and the management of nurse-led clinics. The implications for nursing education are highlighted and discussed

Composition and Method for Radiation Synovectomy of Arthritic Joints

Radioactive microspheres for radiation synovectomy of arthritic joints in a mammal comprises a biodegradable glass material and a beta radiation emitting radioisotope chemically dissolved in and distributed substantially uniformly throughout the glass material. The biodegradable glass material may be lithium silicate, lithium aluminosilicate, lithium aluminoborate, lithium germa- nate, lithium aluminogermanate, potassium silicate, potassium aluminosilicate, potassium aluminoborate, potassium germanate or potassium aluminogermanate and the beta radiation emitting radioisotope may be samarium-153, holmium-166, erbium-169, dysprosium-165, rhenium-186, rhenium-188 or yttrium-90. Method for preparing such microspheres and for carrying out radiation synovectomy of arthritic joints utilizing such microspheres are also disclosed

Microspheres for Radiation Therapy

Microspheres for radiation therapy of a mammal which have a non-radioactive isotope which emits beta or gamma radiation of therapeutic intensity upon being irradiated. The microspheres also contain elements which do not become radioactive upon irradiation. The chemical durability of the microspheres is such that they do not release a significant amount of radiation emitting radioisotope into the mammal’s system upon administration. Microspheres containing phosphorus or yttrium; and carbon, nitrogen, fluorine, sodium, magnesium, aluminum, silicon, potassium, vanadium, manganese, gallium, niobium, iodine and/or lead

Composition and Method for Radiation Synovectomy of Arthritic Joints

A method for preparing nonradioactive microspheres adapted for radiation synovectomy of arthritic joints in a mammal involves forming the microspheres by doping a biodegradable glass material which may be lithium or potassium silicate, lithium or potassium aluminosilicate, lithium or potassium aluminoborate, lithium or potassium germanate or lithium or potassium alumino- germanate with an isotope which may be samarium, holmium, erbium, dysprosium, rhemium or yttrium so that the isotope is chemcially dissolved in and distributed uniformly throughout the glass material. The doped glass material is then treated with an acid wash to produce a thin layer on the surface thereof and heat treated to improve the chemical durability of the glass material by rendering the solubility of the layer lower than that of the underlying glass material
