The Polish TRES-DEP study assesses a number of demographic, clinical and psychometric features comparing patients with treatment-resistant and treatment non-resistant depression. The study included 1083 patients with single or recurrent depressive episode among which 570 met the criteria for treatment-resistant depression, on account of lack of significant improvement following at least two adequate courses of antidepressant treatment. All 1083 patients were assessed by means of the Polish version of Hypomania Check List 32 Scale. The Cronbach's alpha for entire scale was 0.94 which indicates high degree of consistency. Exploratory factor analysis resulted in five factors, of which the biggest (mostly overactivity and elation) containing items1-6, 7-19, 21, 23 and 27 had eigenvalue 10.95 and accounted for 34.2% and the second (irritability), items 25-26, with eigenvalue 2.92, accounted for 9.1% of total variation. Significant differences were obtained between patients with treatment-resistant and treatment non-resistant depression as to the scores of HCL-32. The mean score of HCL-32 was significantly higher in treatment-resistant vs non-resistant depression (11.9±8.3 vs 8.8±7.7, respectively, p< 0.001). Also, the percentage of patients having positive response to 14 or more items of the scale was significantly higher in treatment-resistant than in non-resistant depression (44% vs 29%, respectively, p< 0.001). Based on the results of HCL-32 scale, it may be concluded that the features of bipolarity make the patient more resistant to antidepressant treatment.

Abstract Conjugality refers to the shared experience between partners characterized by an enduring bond. It is related to a high degree of intimacy, affective involvement, and different interpersonal strategies, and it is seen by partners as their most significant relationship. Such intensity makes couple interaction different from any other type of relationship. The objective of this study was to verify how interpersonal attitude of the participants toward their spouses are associated with their partners and the independent interviewer’s perception of their attitudes. The results showed that the participants had a perception of themselves that was, in general, congruent with their partners’ and the interviewer’s perception. However, the spouses agreed more about their relationship roles (dominant or submissive) and disagreed on the dedicated affection (friendly or hostile) between them. In contrast, the interviewer overestimated the subjects’ attempts to control but confirmed the presence of statements of affection. The results obtained also provided a realistic portrait of marital interactions, increasing the application spectrum of the Checklist de Relações Interpessoais (Check list of Interpersonal Transactions).

Исследование направлено на выявление различий в представлениях студентов о совести в зависимости от степени выраженности у них психопатологической симптоматики. Предполагается, что у студентов с выраженной психопатологической симптоматикой сильнее проявится негативная установка по отношению к феномену совести , чем у студентов с минимальными психопатологическими проявлениями . Использовался Опросник выраженности психопатологической симптоматики (Simptom Check List-90-r-Revised, SCL-90-R) и авторская анкета определения социальных представлений о совести. Выборку составили 109 студентов московских ВУЗов, которые были разделены на 2 группы: респондентов с минимальными проявлениями психопатологической симптоматики и с высокой степенью ее выраженности. Гипотеза исследования : социальные представления студентов о совести имеют специфику в зависимости от интенсивности психопатологической симптоматики: у респондентов с выраженной психопатологической симптоматикой сильнее проявится негативная валентность в отношении к феномену совести, чем у респондентов с минимальными психопатологическими проявлениями. Результаты показали, что студенты первой группы статистически чаще соглашаются с негативными представлениями о совести. Тем самым, текущее эмпирическое исследование подтверждает, что психологическое здоровье взаимосвязано с нравственными установками личности и, вероятнее всего, является одним из необходимых условий нравственности человека в целом, как и наоборот, стойкие нравственные ориентиры помогают личности сохранить психическое и психологическое здоровье в сложных жизненных ситуациях. The study aims to identify differences in students' perceptions of conscience, depending on the severity of their psychopathological symptoms. It is assumed that students with severe psychopathological symptoms will show a more negative attitude towards the phenomenon of conscience than students with minimal psychopathological manifestations. The Questionnaire for the severity of psychopathological symptoms (Simptom Check List-90-r-Revised, SCL-90-R) and the author's questionnaire for determining social ideas about conscience are used. The sample consists of 109 students from Moscow universities, which are divided into 2 groups: respondents with minimal manifestations of psychopathological symptoms and respondents with a high degree of severity of psychopathological symptoms. Research hypothesis: students' social perceptions of conscience are specific depending on the intensity of psychopathological symptoms, namely: respondents with severe psychopathological symptoms will show a more negative valence in relation to the conscience phenomenon than respondents with minimal psychopathological manifestations. The results showed that students with a high degree of severity of psychopathological symptoms are statistically more likely to agree with negative ideas about conscience. Thus, we can make a general conclusion that psychological health is interconnected with the moral attitudes of the individual and, most likely, is a necessary condition for human morality, and vice versa, moral guidelines help a person maintain mental and psychological health in difficult life situations.

The morphologic pathologist may require information on the ultrastructure of a non-specific lesion seen under the light microscope before he can make a specific determination. Such lesions, when caused by infectious disease agents, may be sparsely distributed in any organ system. Tissue culture systems, too, may only have widely dispersed foci suitable for ultrastructural study. In these situations, when only a few, small foci in large tissue areas are useful for electron microscopy, it is advantageous to employ a methodology which rapidly selects a single tissue focus that is expected to yield beneficial ultrastructural data from amongst the surrounding tissue. This is in essence what "LIFTING" accomplishes. We have developed LIFTING to a high degree of accuracy and repeatability utilizing the Microlift (Fig 1), and have successfully applied it to tissue culture monolayers, histologic paraffin sections, and tissue blocks with large surface areas that had been initially fixed for either light or electron microscopy.

The visualization of organic macromolecules such as proteins, nucleic acids, viruses and virus components has reached its high degree of effectiveness owing to refinements and reliability of instruments and to the invention of methods for enhancing the structure of these materials within the electron image. The latter techniques have been most important because what can be seen depends upon the molecular and atomic character of the object as modified which is rarely evident in the pristine material. Structure may thus be displayed by the arts of positive and negative staining, shadow casting, replication and other techniques. Enhancement of contrast, which delineates bounds of isolated macromolecules has been effected progressively over the years as illustrated in Figs. 1, 2, 3 and 4 by these methods. We now look to the future wondering what other visions are waiting to be seen. The instrument designers will need to exact from the arts of fabrication the performance that theory has prescribed as well as methods for phase and interference contrast with explorations of the potentialities of very high and very low voltages. Chemistry must play an increasingly important part in future progress by providing specific stain molecules of high visibility, substrates of vanishing “noise” level and means for preservation of molecular structures that usually exist in a solvated condition.

Electron microscope design, and particularly the design of the imaging system, has reached a high degree of perfection. Present objective lenses perform up to their theoretical limit, while the whole imaging system, consisting of three or four lenses, provides very wide ranges of magnification and diffraction camera length with virtually no distortion of the image. Evolution of the electron microscope in to a routine research tool in which objects of steadily increasing thickness are investigated, has made it necessary for the designer to pay special attention to the chromatic aberrations of the magnification system (as distinct from the chromatic aberration of the objective lens). These chromatic aberrations cause edge un-sharpness of the image due to electrons which have suffered energy losses in the object.There exist two kinds of chromatic aberration of the magnification system; the chromatic change of magnification, characterized by the coefficient Cm, and the chromatic change of rotation given by Cp.

Receptor cells of the cristae in the vestibular labyrinth of the bullfrog, Rana catesbiana, show a high degree of morphological organization. Four specialized regions may be distinguished: the apical region, the supranuclear region, the paranuclear region, and the basilar region.The apical region includes a single kinocilium, approximately 40 stereocilia, and many small microvilli all projecting from the apical cell surface into the lumen of the ampulla. A cuticular plate, located at the base of the stereocilia, contains filamentous attachments of the stereocilia, and has the general appearance of a homogeneous aggregation of fine particles (Fig. 1). An accumulation of mitochondria is located within the cytoplasm basal to the cuticular plate.

The optic ganglion of Daphnia Magna, a small crustacean that reproduces parthenogenetically contains about three hundred neurons: 110 neurons in the Lamina or anterior region and about 190 neurons in the Medulla or posterior region. The ganglion lies in the midplane of the organism and shows a high degree of left-right symmetry in its structures. The Lamina neurons form the first projection of the visual output from 176 retinula cells in the compound eye. In order to answer questions about structural invariance under constant genetic background, we have begun to reconstruct in detail the morphology and synaptic connectivity of various neurons in this ganglion from electron micrographs of serial sections (1). The ganglion is sectioned in a dorso-ventra1 direction so as to minimize the cross-sectional area photographed in each section. This area is about 60 μm x 120 μm, and hence most of the ganglion fit in a single 70 mm micrograph at the lowest magnification (685x) available on our Zeiss EM9-S.

Purine Pyrimidine

An ultimate design goal for an improved electron microscope, aimed at biological applications, is the determination of the structure of complex bio-molecules. As a prototype of this class of problems, we propose to examine the possibility of reading DNA sequence by an imaginable instrument design. This problem ideally combines absolute importance and relative simplicity, in as much as the problem of enzyme structure seems to be a much more difficult one.The proposed technique involves the deposition on a thin graphite lamina of intact double helical DNA rods. If the structure can be maintained under vacuum conditions, we can then make use of the high degree of order to greatly reduce the work involved in discriminating between the four possible purine-pyrimidine arrangements in each base plane. The phosphorus atoms of the back bone form in projection (the helical axis being necessarily parallel to the substrate surface) two intertwined sinusoids. If these phosphorus atoms have been located up to a certain point on the molecule, we have available excellent information on the orientation of the base plane at that point, and can then locate in projection the key atoms for discrimination of the four alternatives.
