Detection of antagonistic cellular regulatory functions by the gene-gene interference method in yeast

The objective of the study is, on one hand, to determine the etiology and the clinical implications as a function of the isolated germ, of central venous catheterization in patients with parenteral nutrition in our hospital, and on the other hand, to determine which factors are associated with the selection of germs of central venous catheterization in parenteral nutrition. For this we included venous catheters, colonized for 5 years, and with a study of the different segments (connection, insertion point, and tip). As a function of the appearance of associated clinical symptoms, of the results of the blood culture, and of the clinical evolution of the patient, the variables which determine the level of pathogenicity of the different groups of germs in the central venous catheterization, are defined; for the study of the factors associated with the selection of the different groups of germs, 8 variables were chosen. The data obtained are statistically treated, and the results are considered to be significant if p < 0.05. The understanding of the different factors associated with the selection of germs, and the level of clinical pathogenesis of the different groups, allows a better level of the clinical action in the prevention of the infection associated with the catheter.     

The Free Trade Agreement and environmental health in Mexico

This work offers an overview of the state of the art and future state of environmental health in our country from a viewpoint of the impact of the commercial opening established in the Free Trade Agreement among Mexico, the USA, and Canada. In the first section of this work, we analyze the expected economic changes resulting from the implementation of the FTA and foretells the way in which those changes will influence the present environmental and epidemiologic profiles of this country in the medium and long term. The main changes predicted by the analysis are, in the epidemiologic context, the acceleration of the transference of occupational, consumption, environmental and population risks, characteristic of industrialized countries, to the country's polarized epidemiologic profile; and, in the environmental context, a transition consisting of a broadening and composition of the spectrum of pollutants, including and important lagging of bacteriologic control. The second section offers an analysis of the predicted response capacity facing the new environmental risk dynamics in the country, encompassing regulation, normativeness and enforcement of environmental and consumer protection, as well as obstacles found in health services to the implementation of surveillance, detection and treatment of health damages caused by environmental factors. The analysis of the organized social response to these problems discloses a relative flexibility of the normativeness and enforcement functions in comparison with our northern neighbors, a paramount factor for the possible transference of environmental risks, as well as the informational and research deficiency about environmental issues, basic elements for sustaining environmental health in the country, aiming at speeding up the development and transference of technologies for prevention, detection and management of environmental risks in the country, drawing upon the systematization of our experience and that of our neighbors. This speeding process ought to match, in the medium term, the velocity of risk transference produced by the commercial opening. In this way, the commercial integration of North America will become a favorable context for the development of the environmental health infrastructure of the country.     

THE FORMATION OF URANIUM AND OF BERYLLIUM ALLOYS BY THE SOLID-STATE SINTERING OF MIXED ELEMENTAL POWDERS

Abstract

Large volume expansions accompany the formation of binary alloys of beryllium with uranium, thorium, iron, copper, zirconium, titanium, and vanadium, and of uranium with aluminium, during the sintering of the mixed, cold-compacted elemental powders. No expansion was detected during the sintering of binary mixtures of beryllium with aluminium, silicon, and magnesium, or mixtures of uranium with zirconium, molybdenum, iron, nickel, manganese, and chromium.

When it occurs, expansion is anisotropic, being greatest in the direction of compacting; the degree of anisotropy varies with the constituents and the composition of the alloys. In systems undergoing expansion, the volume expansion/composition graphs exhibit maxima. For a given system the magnitude of the maximum is a function of the shape of compact, the particle size of the powders, and the sintering time and temperature; the composition at which the maximum occurs is sensibly unaffected by these latter variables.

These experimental observations, together with those of other investigators, can be satisfactorily interpreted on the hypothesis that volume expansion is due to the formation of diffusional porosity during sintering.

The symbolism of salt in paintings

Many artists have used the symbol of salt in both religious and profane works, yet very few studies have explored the symbolism of salt as used in works of art. In this study, Panofsky's method has been adopted to evaluate works of art through an organic process articulated into three stages: (1) pre-iconographic, (2) iconographic and (3) iconological. The method was used for (a) religious paintings of the Old and New Testaments and (b) mythological and profane themes. Various salt-cellars were also studied. In particular, the paper examines the following themes: Isaac blessing Jacob, the return of Esau, Samuel consecrating David, the Last Supper, the suppers at Emmaus and at the house of Simon, the birth of St. John the Baptist, the Baptism of Constantine, the prodigal son, Bacchus-Apollo, the nuptial banquet of Love and Psyche, the death of the Cavalier of Celano, the king drinks, the landlord's visit, 'Phitopolis faisant servir des mets en or au roi Pithès', certain still life paintings and various salt-cellars including those of Cellini and Giulio Romano. The paper discusses the works of many artists including Raphael, Leonardo and his school (Boltraffio, Giampietrino, d'Oggiono, Solario), Hendricksz, Corenzio, Jean-Baptiste and Philippe de Champaigne, Damaskinos, Tintoretto, Titian, Romanino, Rubens, Bellini, Bloemaert, Veronese, Sustris, Just of Ghent, Jan Van Hemessen, Poussin, Loir, Giotto, Jordaens, Brueghel and Mimmo Paladino with his enchanted mountain. From the data examined it emerged that salt is a primary iconological presence in various works of art.     

Age-related differences in calcium accumulation in human arteries

To elucidate the accumulation of calcium in the human arteries, the calcium contents of the thoracic aorta, coronary, common carotid, basilar, internal thoracic, axillary, radial, femoral, popliteal, and dorsalis pedis arteries, were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). The calcium content began to increase in both the thoracic aorta and femoral artery around the age of 50 years (yrs), in the popliteal artery at the age of 60 yrs, in the coronary, basilar and dorsalis pedis arteries at the age of 70 yrs, and in the common carotid artery at the age of 80 yrs. In the same time, the calcium content did not increase significantly in the internal thoracic and radial arteries. Accumulation of calcium in human arteries was classified into two groups: The first is an age-related increase of calcium content in the arteries like the thoracic aorta, coronary, common carotid, basilar, axillary, femoral, popliteal and dorsalis pedis arteries. The second is non-age-related, such as the internal thoracic and radial arteries. To examine the localization of this calcium accumulation, the thoracic-aortic and femoral-arterial walls were separated into the three tunicae, intima, media and adventitia. In the case of the thoracic aorta, the accumulation of calcium and phosphorus occurred primarily in the tunica media of aorta, secondarily in the tunica intima. With regard to the femoral artery, the accumulation of calcium and phosphorus occurred only in the tunica media, only in the tunica intima, or in both the tunicae media and intima. Therefore, the manner of accumulation of calcium and phosphorus in the femoral-arterial wall was different from that in the aortic wall. Comparing the upper and lower limb arteries, the calcium content was found to be higher in the femoral, popliteal, and dorsalis pedis arteries of the lower limb than that of the axillary and radial arteries of the upper limb.     

ACTH/CLIP immunoreactivity in the cat brain stem

The distribution of adrenocorticotropin hormone/corticotropin-like intermediate lobe peptide was studied in the cat brain stem, using an indirect immunoperoxidase technique. No immunoreactive cell bodies were observed. However, a high density of immunoreactive fibers was found in the periaqueductal gray, the dorsal nucleus of the raphe, the locus coeruleus, and the marginal nucleus of the brachium conjunctivum. A moderate density was found in the central linear nucleus, the central tegmental field, the Kolliker-Fuse nucleus, the inferior central nucleus, and the postpyramidal nucleus of the raphe. A low density was found in the superior and inferior colliculi, the interpeduncular nucleus, the nucleus sagulum, the superior central nucleus, the cuneiform nucleus, the accessory dorsal tegmental nucleus, the nucleus of the solitary tract, the dorsal motor nucleus of the vagus, and the paralemniscal, magnocellular, gigantocellular, and lateral tegmental fields. Moreover, single immunoreactive fibers were observed in numerous nuclei of the cat brain stem. In comparison with previous studies carried out in the same region of the cat, as well as the rat and the human, our results point to a more widespread distribution of adrenocorticotropin hormone/corticotropin-like intermediate lobe peptide immunoreactive structures in the cat brain stem. This widespread distribution indicates that the peptide might be involved in several physiological functions of the cat brain stem.     

The lymphatic vessels and the so-called "lymphatic stomata" of the diaphragm: a morphologic ultrastructural and three-dimensional study

We studied the absorbing peripheral lymphatic vessel with the light microscope, the transmission electron microscope, the scanning electron microscope, and three-dimensional models of the diaphragm of several rodents and insectivores under normal and experimental conditions (lymphatic stasis and dehydration). To clarify the delicate and complex mechanism that permits drainage of the abdominal cavity contents into the lymphatic circulatory system, we introduced Polystyrene latex spherules, China ink, and Trypan blue into the abdominal cavities. After anatomical comparisons of the superficial and deep networks of absorbing peripheral lymphatic vessels at the tendinous and muscular portions of the diaphragm and after classification of lymphatic vessels into absorbing and conducting functions, we examined the stomata, which, owing to morphologic and topographic findings, we defined as stable structures. Furthermore, we observed that the stomata and submesothelial connective channel are fundamental elements that facilitate the flow of the corpuscular and liquid contents of the peritoneal cavity to the submesothelial absorbing lymphatic vessel wall. Also, we underlined that the genesis of the connective channel depends on the secondary cytoplasm extensions of two distinct adjacent endothelial cells, which, to facilitate the flow of the absorbed abdominal contents, completely coat this channel. Additionally, our observations illustrate that the secondary cytoplasm extensions do not engage in continuous relationships with the basal lamina of the mesothelium and with the margins of the stoma, and, hence, the hypothesis of "lymphatic stomata" as an expression of the anchoring of the borders of the open interendothelial junctions to the orifice margins of the stoma cannot be confirmed. Moreover, we describe the presence and formation of intraendothelial channels in the lymphatic endothelial wall. We affirm that this morphological entity is a dynamic unit, because its numerical density varies according to different physiological and experimental conditions to degrees of hydrostatic and colloidal osmotic pressure and, perhaps, also to the particular characteristics of the substances that the connective channel liberates into the endothelial wall of the lymphatic vessel. In conclusion, we affirm that the absorbing peripheral lymphatic vessels of the diaphragm, by way of intraendothelial channel formations, membrane diffusion, and the vesicular path of the endothelial cells, constitute the fundamental draining elements for the corpuscular and liquid contents of the abdominal cavity.
