Modified cilia in sensory organs of juvenile stages of a parasitic nematode.

Electron microscopical studies revealed the presence of dendritic nerve processes in sensory organs of the third- and fourth-stage juveniles of Haemonchus contortus, which contained structures resembling modified cilia. With few exceptions, the outer circle of fibers consisted of ten doublets, and in place of typical cilia-like central fibers were small microtubules or vesicles varying in number from zero to five.

Burden of care: an important concept for nurses.

Research on family caregiving demonstrates clearly the predominance of women, particularly wives and adult daughters, among the care providers to elderly persons who are frail and chronically ill. It seems that women go to great lengths to care for impaired and elderly relatives, making personal sacrifices, often at great cost to their own health and well-being. Burden of care is a concept emerging in the literature that describes the physical, emotional, social, and financial problems that can be experienced by family caregivers. This concept may be useful to heighten understanding of the family caregiving experience and as such may provide a framework for nursing practice and research. We seek to increase nurses' awareness, through an examination of the burden-of-care literature, of the caregiving experience of women who minister to elderly parents and husbands. We also make a plea for the involvement of nurses with both givers and receivers of care and offer an approach to assessment that incorporates both the meaning and the process of caregiving.

Spousal caregiving in later life: an objective and subjective career.

During later life, as a consequence of the deteriorating health of husbands, numerous women experience a period of spousal caregiving that can be considered a new phase in their caregiving career. This phase, which often precedes widowhood, is one that has been relatively neglected by researchers. In this article, the concepts of objective and subjective career (Hughes, 1971) are used as orienting concepts to examine the phenomenon of spousal caregiving in later life. Objectively, the caregiving career is seen as an age-related, gender-specific, and role-contingent phenomenon. The subjective career is seen as the meaning and purposes attributed to complex and extensive responsibilities and activities of caregiving and their potentially serious consequences for health and well-being.

Mass spectrometric analysis of anatoxin-a.

Secondary ion mass spectrometry (SIMS), gas chromatography/mass spectrometry (GC/MS), desorption chemical ionization/mass spectrometry (DCI/MS), and thermospray/mass spectrometry (TSP/MS) were evaluated for the detection of a low-molecular weight biological toxin, anatoxin-a. The lowest detection limit was obtained using isobutane or ammonia DCI/MS. Tandem mass spectrometry (MS/MS) was used to enhance the selectivity and sensitivity of the analysis. The detection limit for the pure material is 10 pg, and 100 pg of the toxin can be analyzed directly from urine using DCI/MS/MS.

Continuing education for staff in long-term care facilities: corporate philosophies and approaches.

The purpose of this study was to determine corporate philosophies of continuing education and approaches to meeting the learning needs of staff who strive to provide for the increasingly challenging care requirements of seniors who reside in long-term care facilities. In-depth interviews lasting approximately 1 hour were conducted with key informants at the administrative level from nine long-term care facilities. Content analysis revealed a commitment to continuing education for staff. While recognizing the importance of organizational responsibility for continuing education, administrators placed emphasis on the individual responsibility of staff. Learning needs were identified as affective, managerial, and physical in nature. Challenges to providing continuing education programs were derived from a general lack of fiscal and human resources. A variety of measures was suggested as important to supporting the continuing learning of staff. Implications of this study point to the need for long-term care facilities to incorporate into their strategic plans measures of ensuring continuing education as a basis for the ongoing competence and development of staff. In addition, there is a need for collaboration between long-term care facilities and other institutions of a long-term care, acute care, and educational nature in the development of strategies to operationalize a philosophy of continuing learning as a basis for the provision of optimal care to residents.

Beyond the family: informal support in later life.

This paper adopts the position that although the Canadian family is, and will continue to be an important source of support for its older members, there are limitations in its ability to do so. These limitations have to do with demographic and social changes occurring in contemporary society and highlight the importance of looking to alternative sources of support emerging in the literature as significant to people in their later years. These alternative sources of support which have potential importance for health and wellbeing in later life, have to a large extent been neglected by health care providers. It is suggested that health care practitioners expand the notion of family as the unit of care, which is central to their practice, to include sources of support beyond the immediate family.
