A strategy for managing change and stress. Developing staff support groups.

If change is stress-inducing, nursing must be one of the most stressful professions around. The profession is currently battling through a seemingly endless series of developments at all levels, which must affect individual practitioners. One way of minimising stress on nurses is to set up peer support groups.

Features of "near-death experience" in relation to whether or not patients were near death.

The medical records of 58 patients, most of whom believed they were near death during an illness or after an injury and all of whom later remembered unusual experiences occurring at the time, were examined. 28 patients were judged to have been so close to death that they would have died without medical intervention; the other 30 patients were not in danger of dying although most of them thought they were. Patients of both groups reported closely similar experiences but patients who really were close to death were more likely than those who were not to report an enhanced perception of light and enhanced cognitive powers. The claim of enhancement of cognitive functions despite the likelihood that brain function had probably become disturbed and possibly diminished, deserves further investigation.

Near-death experiences in India. A preliminary report.

The authors report some features of 16 cases of near-death experiences that they investigated in India. After presenting brief accounts of four such experiences, the authors describe and discuss features in which the Indian cases differ from a larger sample of American cases. They note that some of these features seem to be culture-bound, but they caution against accepting this observation as adequate evidence that the case derive only from culture-bound beliefs. Some differences may derive from the effects of a person's beliefs on what actually does happen after death, and some different features may, on closer examination, be found to be basically similar in nature if not in detail.

Protoplast formation from submerged mycelium and from spore germinants of Streptomyces coelicolor.

Stages in the formation of protoplasts from S. coelicolor strain A3(2) have been studied by transmission electron microscopy. Protoplasts liberated from submerged mycelial growth were variable in size and were released when digestion of the cell wall by lysozyme had completely or almost completely taken place. Protoplasts did not fully adopt the typical rounded shape until after release. A single region of cytoplasm gave rise to more than one protoplast unit. Protoplasts released from spore germinants escaped from the tip of the germ tube, which was the region of the cell wall most susceptible to digestion. Protoplasts derived from spore germinants were more consistent in size and rounded up more rapidly. If a cross-wall had formed in a germinant then it gave rise to separate protoplasts from each cellular compartment. Protoplasts of either type contained a single DNA region. These studies give an indication of the cellular organization of a streptomycete colony, which can be visualized as a multinucleated assemblage of cellular units in a common cytoplasm. The assembly of units separates into a number of protoplasts on digestion of the cell wall.

Ribonucleic acid stimulation of mammalian liver nuclear-envelope nucleoside triphosphatase. A possible enzymic marker for the nuclear envelope.

1. The specific activity of rat and pig liver nuclear-envelope nucleoside triphosphatase (EC 3.6.1.3) decreases when the system is depleted of RNA. The activity can be restored by adding high concentrations of yeast RNA to the assay medium. 2. Exogenous RNA also increases the activity of the enzyme in control envelopes (not RNA-depleted). The effect appears to be largely specific for poly(A) and poly(G); it is not stimulated by rRNA or tRNA preparations, ribonuclease-hydrolysed RNA, AMP, or double- or single-stranded DNA. 3. Inhibitors of the enzyme, in concentrations at which half-maximal inhibition of the enzyme is achieved, do not affect the percentage stimulation of the enzyme by yeast RNA. 4. The simulation is abolished by the inclusion of 150 mM-KCl or -NaCl in the assay medium, but not by increasing the assay pH to 8.5. 5. The results are discussed in the light of the possible role of the nucleoside triphosphatase in vivo in nucleo-cytoplasmic ribonucleoprotein translocation. 6. It is proposed that poly(G)-stimulated Mg2+-activated adenosine triphosphatase activity should be adopted as an enzymic marker for the nuclear envelope.

The explanatory value of the idea of reincarnation.

The idea of reincarnation is presented as having considerable explanatory value for several features of human personality and biology that currently accepted theories do not adequately clarify. Reincarnation is not offered as a substitute for present knowledge derived from genetics and understanding of environmental influences; it may, however, usefully supplement such knowledge. The present paper does not present evidence from cases suggestive of reincarnation. It does, however, cite cases of subjects who have claimed to remember previous lives, most of whose statements have been verified in the course of detailed investigations. For each case, a reference is provided to a detailed published case report furnishing the evidence in that case. The idea of reincarnation may contribute to an improved understanding of such diverse matters as: phobias and philias of childhood; skills not learned in early life; abnormalities of child-parent relationships; vendettas and bellicose nationalism; childhood sexuality and gender identity confusion; birthmarks, congenital deformities, and internal diseases; differences between members of monozygotic twin pairs; and abnormal appetites during pregnancy. Empirical studies of cases of the reincarnation type have so far not provided any evidence that justifies using reincarnation as an explanation for the occurrence of child prodigies of the large inequities in socioeconomic conditions of humans at birth.

The Southeast Asian interpretation of gender dysphoria: an illustrative case report.

In the West gender dysphoria is commonly attributed to a biological abnormality, parental influences favoring assumption of a gender opposite to the subject's anatomical sex, or a combination of these factors. In Southeast Asia (among Hindus and Buddhists), numerous cases of gender dysphoria occur. They generally receive less attention than they do in the West and evoke relatively little concern on the part of the persons affected and the members of their families. The condition is attribwted to residues of a previous life as a member of the opposite sex. Some persons with gender identity confusion claim to remember details of previous lives. A case illustrating such claims (without verifiable details) is presented.
