African-American women who smoke crack cocaine: sexual trauma and the mother-daughter relationship.
This study evolved from previous writings that linked sexual abuse to the quality of the mother-daughter relationship. The purpose of this investigation was to examine the mother-daughter relationship among African-American women who abuse crack cocaine by comparing three different groups: women who have not experienced incest but have experienced sexual abuse; women who have experienced incest; and women who have not experienced sexual abuse. A convenience sample of 64 African-American women was used, 35 of whom were in drug abuse treatment and 29 of whom were abusing crack cocaine. Using analysis of variance studies, significant differences were found between the three groups in terms of the mother-daughter relationship. Differences were also found between the group that experienced incest and the group that experienced nonincestuous sexual abuse in terms of the amount of abuse and first age of abuse. This preliminary investigation indicates the need for further study of specific populations in this area--most notably, African-American women who abuse crack cocaine.

Two different classes of avrD alleles occur in pathovars of Pseudomonas syringae.
Considerable variation was observed in the occurrence of avirulence gene D (avrD) in different isolates and pathovars of Pseudomonas syringae. Three functional alleles of avrD were cloned and characterized from P. s. pv. phaseolicola and P. s. pv. lachrymans. These avrD genes occurred on indigenous plasmids in both pathovars, like the allele originally cloned from P. s. pv. tomato. P. s. pv. lachrymans was unique in that it carried two different alleles on plasmids of different sizes. These alleles were cloned on 5.6- or 3.8-kb HindIII fragments that are conserved in several other P. syringae pathovars. Surprisingly, the two avrD alleles from P. s. pv. lachrymans were the most divergent of those compared, with only 85% amino acid identity. Allele 1 from P. s. pv. lachrymans was 95% identical to avrD from P. s. pv. tomato but less similar to the other three avrD genes. These two alleles were accordingly called homology class I. The avrD gene from P. s. pv. phaseolicola and allele 2 from P. s. pv. lachrymans were 97 and 98% identical, respectively, at the amino acid level with the nonfunctional P. s. pv. glycinea allele. These three alleles were therefore grouped into homology class II. Comparison of all the avrD alleles permitted the identification of four amino acid substitutions unique to the P. s. pv. glycinea allele at positions 19, 245, 280, and 304.

Avirulence gene avrPphC from Pseudomonas syringae pv. phaseolicola 3121: a plasmid-borne homologue of avrC closely linked to an avrD allele.
Cosmid clone pPsp01 from race 1 Pseudomonas syringae pv. phaseolicola isolate 3121 conferred a unique pattern of soybean cultivar reactions when expressed in P. s. pv. glycinea R4. The avirulence phenotype was shown to result from the presence in clone pPsp01 of an avrD allele as well as an additional avirulence gene located approximately 5-kb upstream. The new gene, called avrPphC, shows high identity to and is phenotypically identical to avrC, previously cloned from P. s. pv. glycinea race 0. avrD and avrPphC occur on an approximately 120-kb indigenous plasmid in P. s. pv. phaseolicola 3121. Although commonly observed in Xanthomonas campestris, this is the first noted occurrence of multiple avirulence genes on a single plasmid in Pseudomonas syringae. Unlike avrD, however, avrPphC does not appear to occur widely in pathovars of Pseudomonas syringae.

Autonomic and cardiovascular effects of neuromuscular blockade antagonism in the dog.
Autonomic and cardiovascular changes were studied when neuromuscular blockade was antagonized in 96 dogs with one of eight anticholinesterase-antimuscarinic drug combinations. Neostigmine (50 or 100 micrograms/kg) was administered before or after atropine (40 micrograms/kg) or glycopyrrolate (10 micrograms/kg). The high dose of neostigmine (100 micrograms/kg) caused bradyarrhythmias, salivation, and signs of bronchosecretion when used with either antimuscarinic agent and irrespective of the administration sequence. The heart rate increased, but not significantly, when atropine was injected before either dose of neostigmine. This did not occur when this administration sequence was reversed. Arrhythmias and cardiovascular and autonomic changes did not occur when glycopyrrolate was injected before or after neostigmine at 50 micrograms/kg.

All my buddies was male: relationship issues of women with addictions.
There is a common perception that women who abuse drugs and alcohol do not like women. How does this attitude relate to women's abuse of drugs, and what difference might it make to the nursing care of addicted women. The importance of relationships to self and others has been emphasized in nursing theories, recent theories of women's psychologic development, and the social models used to explain substance abuse. This article examines what is known about the interpersonal relationships of women with addictions, including those with men and with other women, and explores how those relationships are associated with women's substance abuse behaviors. A brief explanation of current theories of women's psychologic development is followed by a review of the literature regarding the relationships of women with addiction problems, highlighting their attitudes toward themselves as women and the importance of the adult mother-daughter relationship. Implications for the treatment of addicted women by nurses are discussed.

Developing a standards based critical care program.
The American Association of Critical-Care Nurses (AACN) has established accepted levels of care standards for critically ill patients. One institution's use of the AACN standards in the development, implementation, and evaluation of a competency-based critical care nursing program is reported.

Analysis of the impact of mother-daughter relationships on the commitment to caregiving.
Path analysis was used to test a model to examine the impact of mother-daughter relationships on the commitment to caregiving by 98 adult daughters during the first three months. Findings generally supported the model. Although significant, magnitude of mothers' limitations did not solely explain commitment, either instrumental or affective. Mother-daughter relationships were powerful predictors of commitment, especially affective commitment. Although predicted, employment status did not function as a mediator in this model, while living arrangements did.
