The physician's role in maintaining hope and spirituality

This paper examines several areas that health care providers may find difficult in the care of patients near the end of their lives. It looks at society's denial of death and at ways physicians and their patients use ongoing active treatments to maintain that denial. It suggests that as active treatment fails to be effective and hope fades, physicians must find ways to care for those they cannot cure. It explores the function of hope to help physicians, their patients, and their patients' families redirect their thinking. Finally, it describes how the physician may support a patient's spirituality by becoming more comfortable with his own.     

The dynamics of somatosensory and visual evoked potentials as a correlate of reversible states of altered consciousness]

Somatosensory and visual evoked potentials (EPs) of the brain of 17 sensitive subjects (extrasenses) and 12 ordinary healthy subjects were studied. It was found that during extrasensory activity (direct impact, meditation) in comparison to rest values, the amplitude of intermediate and late components of visual and somatosensory EPs of both hemispheres and early components of somatosensory EPs of ipsilateral in relation to stimulation hemisphere diminished 2-4--fold. There was a recovery of these components after discontinuation of extrasensory activity. It is shown that ordinary subjects could not change their EPs when they tried their best to decrease EPs. It is shown that ordinary subjects could not change their EPs when they tried their best to decrease EPs. It is suggested that the ability of extrasenses for reversible changes of their mind by direct adjustment of the activity of the ascending nonspecific systems of the brain and by alterations of interhemispheric relations forms the basis of extrasensory activity.

The Ethological–Physiological Response of <Emphasis Type="Italic">Apis mellifera</Emphasis> L. Bees to Carbohydrate Lead Contamination

The response of bees to lead contamination of a carbohydrate feed has been studied. It was established that Pb in sucrose solution had a toxic and repelling effect on the bees. It was found that the amount of contaminated feed consumed by the bees decreased with a corresponding increase in the content of Pb in it. It is noted that this element accumulates unevenly in different body parts and parts of the digestive tract of the bees, thereby affecting their metabolic activity and accelerating processes of physiological aging, and the specific reaction of the bees to contaminated feed is expressed in their rejection of its consumption and in inhibition of their locomotion.     

Acoustic signal characters in interspecific hybrids of bank and red-backed voles

It has been found that distress signals of bank and northern red-backed voles and their hybrids do not differ in qualitative characters, but the modes of the acoustic signal parameters in many cases differ in the hybrids depending on their origin and can be correlated with the inheritance of some morphological characters that are typical for the species. It is noted that the distress-signal frequencies (quartiles) differ significantly in the first-generation hybrids of various origin and their characteristics are closer to those of the paternal parent species. It has been found that the inheritance of the frequency characteristics by the second-generation hybrids does not have a well-pronounced regularity.     

Lymphocytotoxins in Leukaemia

Fifteen out of 51 patients with leukaemia have produced a lymphocytotoxin in their serum which reacts with their own and a high percentage of all other lymphocytes. This is probably a protein, but not an antibody. It has been detected only before or early during cytotoxic treatment, or during a relapse. It is postulated that the lymphocytotoxin is a specific protein produced by the leukaemic cells, which may facilitate their spread in the body.     

Genetics,History, and Identity: The Case of the Bene Israel and the Lemba

The paper examines the impact of genetic research on the religious identity of the Bene Israel Indian Jewish community and the Lemba Judaising group of southern Africa. It demonstrates how DNA tests which happened to support the possibility of the communities' legends of origin affected their self-perception, the way they are viewed by their neighbors, and their image in the West. It is argued that in both cases what accounted most for the Bene Israel and Lemba responses to the tests was the way the results were portrayed in the mass media, the history of the development of Judaism in their communities, and the local realities.     

Uncomprising activist: Richard Greener,first black graduate of Harvard College

This article investigates what narrations on the symbolic complex of virginity in the life-stories of second-generation women of Moroccan descent in The Netherlands can tell us about the ways these women construct, maintain and combine their various social identifications. It is demonstrated that these biographical narratives contain numerous episodes in which the women improvise upon and shift the meanings of Moroccan core-values like virginity and obedience to one's parents. It is argued that they do so in ways that allow their identifying with values that are cherished within Moroccan circles to be combined with upholding cultural notions that are highly valued by Dutch peers with whom they also identify. It is also pointed out, however, that their drawing upon multicultural capital to create new strategies of living is not without constraints.     

Potential open reading frames in 5′-untranslated regions of eukaryotic mRNA

It is known that 5′-untranslated sequences of eukaryotic mRNA often contain AUG triplets, which can serve as translation initiation sites. It is assumed that such leader open reading frames can perform regulatory functions and code functionally active proteins; however, their characteristics have been studied insufficiently. In the article, the context organization of leader open reading frames of eukaryotic mRNA was considered. It was shown that their characteristics correlate with their position with respect to the protein-coding sequence, which may be related to the translation initiation efficiency.
