Spirituality/religiosity and cardiovascular system

Introduction: Spirituality/religiosity is associated to well-being. In this article, we describe the association between spirituality/religiosity and cardiovascular system. Materials and methods: We performed searches using Medline, SciELO, Lilacs and Cochrane databases using crossing between the keywords “spirituality,” “cardiovascular system,” “parasympathetic nervous system,” and “sympathetic nervous system.”Results: The electronic search yielded 65 references by crossing the terms “spirituality” and “cardiovascular system.” Among these, the first round of elimination resulted in exclusion of 55 titles and abstracts that were not clearly related to the subject of the review. The titles of the remaining 10 abstracts were submitted to a final evaluation that accounted for the inclusion criteria. An investigation into the reference lists confirmed the absence of relevant documents. Summaries of the analysed studies were selected. Discussion: Among 10 studies selected, 8 of them indicated that spirituality/religiosity is very important for the cardiovascular system, whereas only 2 found no significant association between the two variables in women. Conclusion: We suggest that spirituality/religiosity is an alternative and non-pharmacological therapy for cardiovascular disorders.

Retrospective study of 32 encephalic tumors diagnosed by advanced - image magnetic resonance imaging and computed tomography

The incidence of encephalic tumors in dogs and cats has increased in recent years due to the constant advancement of methods of specialist Diagnostic Imaging: Magnetic Resonance Imaging (MRI) and Computed Tomography (CT), used in small animals. These tools, which were distant in the past, are now becoming increasingly important as an additional aid to the identification of tumor processes in the Central Nervous System. The objective, of the present study, was describe imaging findings obtained in 32 cases of encephalic tumors, through techniques of CT and MR imaging procedures during the years 2004 to 2011. Were diagnosed 19/32 by MRI and 13/32 by CT, being the most affected breed Boxer (9/32), the mean age was 10 years.

Toxoplasmosis: morphological and morphometric evaluation of spinal cord neurons from nonsymptomatic seropositive dogs

The aim of this work was to analyze the neuron morphology and morphometry of cervical, thoracic and lumbar areas of nonsymptomatic seropositive dogs’ spinal cord for toxoplasmosis. Twenty indefinite-breed adult dogs were used; ten dogs were healthy, with negative serology for toxoplasmosis, and were used as the control group (group 1), and ten dogs were nonsymptomatic but seropositive for toxoplasmosis (group 2). After the microtomy, with interval of 100 micrometers (µm), the histological 5-µm-thick cuts were dyed by hematoxylin-eosin and Masson's trichrome techniques. The glass slides were analyzed under light microscope to examine the neuron morphology. The parameters considered for the morphometric analysis were area, perimeter, maximum diameter, minimum diameter and shape factor of cytoplasm and nucleus of neuron. The results were statistically analyzed by Student’s t test at 5% probability level. The morphological characteristics between the two groups were similar and according to literature. The morphometric results showed that there were changes in neurons size and structure, and increase and loss of star shape were noticed in seropositive animals. The results suggest that the neurons of these dogs, yet nonsymptomatic, can have lost their conductor function.

Immunolocalization of myosin Va in the developing nervous system of embryonic chicks

Myosins are molecular motors associated with the actin cytoskeleton that participate in the mechanisms of cellular motility. During the development of the nervous system, migration of nerve cells to specific sites, extension of growth cones, and axonal transport are dramatic manifestations of cellular motility. We demonstrate, via immunoblots, the expression of myosin Va during early stages of embryonic development in chicks, extending from the blastocyst period to the beginning of the fetal period. The expression of myosin Va in specific regions and cellular structures of the nervous system during these early stages was determined by immunocytochemistry using a polyclonal antibody. Whole mounts of chick embryos at 24-30-h stages showed intense immunoreactivity of the neural tube in formation along its full extent. Cross-sections at these stages of development showed strong labeling in neuroepithelial cells at the basal and apical regions of the neural tube wall. Embryos at more advanced periods of development (48h and 72 h) showed distinctive immunolabeling of neuroepithelial cells, neuroblasts and their cytoplasmic extensions in the mantle layer of the stratified neural tube wall, and neuroblasts and their cytoplasmic extensions in the internal wall of the optic cup, as well as a striking labeling of cells in the apparent nuclei of cranial nerves and budding fibers. These immunolocalization studies indicate temporal and site-specific expression of myosin Va during chick embryo development, suggesting that myosin Va expression is related to recruitment for specific cellular tasks.

Interaction between the septal area and the subfornical organ in the control of water intake induced by thirst-eliciting procedures

Rats bearing lesions in the septal area followed by lesions in the subfornical organ were submitted to various thirst-eliciting procedures. The rats with hyperdipsia induced by lesions of the septal area drank more water than either during the control period or after lesion of the subfornical organ under the same thirst-eliciting or angiotensin-liberating stimuli (polyethyleneglycol, isoproterenol, water deprivation and ligation of the inferior vena cava). The overdrinking elicited by lesions in the septal area was blocked after lesion of the subfornical organ. Neither hypovolemia, nor hypotension or water deprivation could elicit increased water intake in animals whose subfornical organ had been destroyed. Animals with lesions in the subfornical organ showed decreased water intake after cellular dehydration. The results obtained suggest that the subfornical organ acts as a more important structure than the septal area in the regulation of water intake elicited by angiotensin, with two opposite effects: a direct one facilitating water intake, and an indirect one inhibiting the septal area. The septal area has an inhibitory effect on the subfornical organ and on water intake. © 1980.

Atrichia, abnormal EEG, epilepsy and mental retardation in two sisters

Two daughters of a nonconsanguineous couple are described. Both present mental retardation, epileptic seizures, congenital atrichia, histologically anomalous skin and abnormal EEG pattern. From a discussion of the literature on atrichia, the forms without involvement of teeth, nails and hidrosis, among which recessive inheritance prevails, are distinguished from each other. None of them coincide with the syndrome described here.

The control of sodium chloride intake: Functional relationship between hypothalamic inhibitory areas and amygdaloid complex stimulating areas

Sodium chloride intake was studied in rats submitted to different neurosurgical procedures. Intake decreased in animals submitted to bilateral destruction of the basolateral amygdaloid complex, and increased after the same animals were submitted to destruction of the anterior lateral hypothalamus, a procedure which is known to cause increased intake in intact rats. In the reverse experiment, where the anterior lateral hypothalamus was destroyed before the basolateral amygdaloid complex, the effect of increased sodium chloride intake induced by destruction of the hypothalamus overcame the decreased expected upon destruction of the amygdaloid complex. These results permit us to conclude that the hypothalamic areas which inhibit sodium chloride intake predominate over the stimulating areas of the amygdaloid complex in the control of sodium chloride intake. © 1981 ANKHO International Inc.

Alcohol levels in cerebrospinal fluid and blood samples from patients under pathological conditions

We measured alcohol levels by the Cordebard method in 148 CSF samples from individuals who had abstained from alcohol for at least 7 days prior to the beginning of the study. Each blood sample was accompanied by a CSF sample from the same patient. CSF samples found to be normal after analysis were used as controls. Mean alcohol concentration in blood did not differ significantly between the control group and the groups with altered CSF. The group with altered CSF had statistically higher alcohol levels in CSF than in blood. CSF lactate, glucose and protein levels were not correlated with alcohol level. The results suggest the presence of endogenous alcohol in the CSF, with levels increasing in the presence of pathological processes involving the nervous system.

Association between bruxism, alcohol and tobaco use among brazilian students

The etiology of bruxism is not well defined. Different factors affecting the central nervous system are considered as risk factors for bruxism. Dental students are not immune to the bruxism, alcohol consumption and tobacco use, despite their training, knowledge of its effects and social responsibility. The purpose of this study was to evaluate the association between bruxism, alcohol consumption and tobacco use among Brazilian dental students. Participants were chosen among 180, 17-29 year-old students at the UNESP’s Dentistry School – Araçatuba Campus. They were divided into those with and without bruxism on the basis at validated clinical criteria. The clinical examinations were carried out by four standardized examiners (Intraexaminer and Interexaminer Unweighted kappa= 0.82, Weighted kappa= 0.89, respectively), in the clinic, with daylight and a tongue depressor. Bruxism was registered with the following categories: no wear facets, wear facets in enamel, dentine wear facets, facets wear half of the crown and wear facets more than 2/3 of the tooth crown. A self report validated questionnaire for alcohol consumption and tobacco use with 29 questions was completed by both groups. Fischer exact test and T-test were used and Odds Ratio and Confidence Interval was estimated. Bruxism was more frequent among cigarette smokers both in men (68.4%) and in women (56.8%). Among all respondents in this group, 82.6% reported that they would like to quit smoking and those who have tried previously to quit (76.4%) found it made them more stressed. Drinker was more frequent in the group with bruxism also (66.5% of the female and 73.5% of the male). 88.4% reported drinking alcohol because it “allows dealing with stress in an adequate way”. Results suggest a positive association between bruxism and alcohol consumption and tobacco use.
