Effect of the consumption of a symbiotic shake on the intestinal microflora of erdely people

The consumption of foods containing probiotic and prebiotic ingredients is growing consistently every year, and in view of the limited number of studies investigating their effect in the elderly. Objective The objective of this study was to evaluate the effect of the consumption of a symbiotic shake containing Lactobacillus acidophilus, Bifidobacterium bifidum and fructooligosaccharides on glycemia and cholesterol levels in elderly people. Methods A randomized, double-blind, placebo-controlled study was conducted on twenty volunteers (ten for placebo group and ten for symbiotic group), aged 50 to 60 years. The criteria for inclusion in the study were: total cholesterol > 200 mg/dL; triglycerides > 200 mg/dL and glycemia > 110 mg/dL. Over a total test period of 30 days, 10 individuals (the symbiotic group) consumed a daily dose of 200 mL of a symbiotic shake containing 108 UFC/mL Lactobacillus acidophilus, 108 UFC/mL Bifidobacterium bifidum and 2 g oligofructose, while 10 other volunteers (the placebo group) drank daily the same amount of a shake that did not contain any symbiotic bacteria. Blood samples were collected 15 days prior to the start of the experiment and at 10-day intervals after the beginning of the shake intake. The standard lipid profile (total cholesterol, triglycerides and HDL cholesterol) and glycemia, or blood sugar levels, were evaluated by an enzyme colorimetric assay. Results The results of the symbiotic group showed a non-significant reduction (P > 0.05) in total cholesterol and triglycerides, a significant increase (P < 0.05) in HDL cholesterol and a significant reduction (P < 0.05) in fasting glycemia. No significant changes were observed in the placebo group. Conclusion The consumption of symbiotic shake resulted in a significant increase in HDL and a significant decrease of glycemia.

Amorphous calcium phosphate sealants: remineralization of carious lesions in the enamel can be achieved with use of pit-and-fissure sealants containing amorphous calcium phosphate

New pit-and-fissure sealants with the capacity to release calcium and phosphate because of the presence of ACP have been introduced into the dental marketplace. With the continuous introduction of new dental materials, it is important not only to research and confirm their properties, but also to propose modifications or associations that may contribute to their improvement.

Therapist’s directive and nondirective behavior: analysis of their effects in a parent training group

The study described the interaction between therapist and clients in a group intervention with two mothers and a grandmother. Five out of thirteen taped sessions were designated for analysis. Main results: a) therapist’s categories that stood out: approval, recommendation, interpretation, information and information request; b) clients’ categories that stood out: report, agreement, relation, and opposition, c) the probability for recommendation coupled with use of approval exceeded the probability of occurrence of other combinations. Possible explanations for the results were offered and new research questions were raised.

Study of stillage biodegradation by respirometry in sandy and clay soils

The stillage, which is a liquid residue from the distillation of the sugarcane ethanolic fermentation, contains organic matter and can be a big source of pollution when it is discarded in the wrong way. Its application as fertilizer has been extended, which is reason to cause concerns regarding the environment. The aim of this work was to evaluate and quantify the biodegradation of stillage in sandy and clay soils, besides verifying the efficiency of the Embiotic Line®inoculum as an accelerator of the biodegradation. Bartha and Pramer respirometric technique was used to determine the production of CO2 during the 50 days of the biodegradation process, and the quantification of the initial and final microorganisms was also conducted. Results were analyzed using the Friedman statistical test. Clay soils were significantly better on stillage decomposition when compared to sandy soils (p=0.0153). Clay soils presented greater efficiency in stillage biodegradation, with higher field capacity, better water, organic matter and microbial retention. Regarding the use of the embiotic line, the experiment has shown this product does not interfere positively in the stillage biodegradation for both soils, possibly needing adjustments in its composition.

Taxonomic Characters in the Genus Echinococcus (Cestoda: Taenlidae)

Not more than four species of cestodes of the genus Echinococcus Rudolphi, 1801, are recognized as valid. The larval stage of at least three of them is able to develop in man, causing respective types of hydatid disease. Accurate characterization of these cestodes, including both larval and adult stages, is essential for identification, upon which depends development of methods for preventing infection of man and domestic animals. Because morphological characteristics of the larval cestodes may be modified according to the species of host in which they develop, identification should be based upon taxonomic characters of specimens from the respective natural hosts, which can be identified by means of ecological investigations in endemic areas in combination with controlled infection of experimental animals. The morphological and biological characteristics of the known species are discussed, and the two species most important to public health and economically--E. granulosus (Batsch, 1786) and E. multilocularis Leuckart, 1863--are distinguished. French résumé: Trois espèces de cestodes du genre Echinococcus Rudolphi, 1801 ont été identifiées: E. granulosus (Batsch, 1786); E. multilocularis Leuckart, 1863; et E. oligarthrus (Diesing, 1863). On n'a pas encore déterminé avec certitude s'il fallait leur adjoindre E. patagonicus Szidat, 1960. Ce dernier mis à part, tous ces ténias sont connus pour provoquer chez l'homme des formes spécifiques d'échinococcose hydatique; l'infestation par les larves de E. granulosus est également fréquente chez les ongulés domestiques et la répartition de ce cestode est presque cosmopolite. E. multilocularis est très largement répandu dans l'hémisphère nord, tandis que E. oligarthrus ne se trouve que dans le centre et le sud de I'Amérique. Pour définir des critères morphologiques qui permettent de distinguer avec précision les différentes espèces d'Echinococcus, il convient de prendre les spécimens sur leurs hôtes naturels, sinon l'évolution du stade strobilaire se trouve habituellement retardée et le stade larvaire présente une gamme étendue de variations morphologiques. Pour identifier les hôtes naturels, il faut étudier l'écologie dans les zones d'éndemicité, ainsi que les manifestations de l'infection contrôlée chez des animaux d'expérience. Le stade strobilaire des ténias peut présenter plusieurs caractères spécifiques importants qui concernent notamment la taille, le nombre et la répartition des testicules, la position du pore génital dans les segments gravides, la forme de l'utérus gravide et, dans certains cas, la taille et la forme des crochets du rostre. La structure de la larve normalement développée est caractéristique de chacune des trois espèces relativement bien connues. Les caractéristiques biologiques jouent également un rôle important dans la différenciation de ces cestodes. Au stade larvaire, le laps de temps nécessaire au développement des scolex infectants est directement fonction de la durée de vie de l'hôte intermédiaire. La larve de E. multilocularis présente des scolex infectants dès le deuxième ou le troisième mois, alors qu'ils n'apparaissent qu'au bout d'un ou deux ans chez la larve de E. granulosus. Un tableau donne la liste comparative des caractéristiques taxonomiques qui permettent de faire la distinction entre ces deux espèces.

Pissing Glass and the Body Crass: Adaptations of the Scatological in Théophile

Examination of scatological motifs in Théophile de Viau’s (1590-1626) libertine, or ‘cabaret’ poetry is important in terms of how the scatological contributes to the depiction of the Early Modern body in the French lyric.1 This essay does not examine Théophile’s portrait of the body strictly in terms of the ‘Baroque’ or the ‘neo-Classical.’ Rather, it argues that the scatological context in which he situates the body (either his, or those of others), reflects a keen sensibility of the body representative of the transition between these two eras. Théophile reinforces what Bernard Beugnot terms the body’s inherent ‘eloquence’ (17), or what Patrick Dandrey describes as an innate ‘textuality’ in what the body ‘writes’ (31), and how it discloses meaning. The poet’s scatological lyric, much of which was published in the Pamasse Satyrique of 1622, projects a different view of the body’s ‘eloquence’ by depicting a certain realism and honesty about the body as well as the pleasure and suffering it experiences. This Baroque realism, which derives from a sense of the grotesque and the salacious, finds itself in conflict with the Classical body which is frequently characterized as elegant, adorned, and ‘domesticated’ (Beugnot 25). Théophile’s private body is completely exposed, and, unlike the public body of the court, does not rely on masking and pretension to define itself. Mitchell Greenberg contends that the body in late sixteenth-century and early seventeenth-century French literature is often depicted in a chaotic manner because, ‘the French body politic was rent by tumultuous religious and social upheavals’ (62).2 While one could argue that Théophile’s portraits of a syphilis-ridden narrators are more a reflection of his personal agony rather than that of France as a whole, what emerges in Théophile is an emphasis on the movement, if not decomposition of the body.3 Given Théophile’s public persona and the satirical dimension of his work, it is difficult to imagine that the degeneration he portrays is limited only to his individual experience. On a collective level, Théophile reflects what Greenberg calls ‘a continued, if skewed apprehension of the world in both its physical and metaphysical dimensions’(62–3) typical of the era. To a large extent, the body Théophile depicts is a scatological body, one whose deterioration takes the form of waste, disease, and evacuation as represented in both the private and public domain. Of course, one could cast aside any serious reading of Théophile’s libertine verse, and virtually all of scatological literature for that matter, as an immature indulgence in the prurient. Nonetheless, it was for his dissolute behavior and his scatological poetry that Théophile was imprisoned and condemned to death. Consequently, this part of his work merits serious consideration in terms of the personal and poetic (if not occasionally political) statement it represents. With the exception of Claire Gaudiani’s outstanding critical edition of Théophile’s cabaret lyric, there exist no extensive studies of the poet’s libertine œuvre.4 Clearly however, these poems should be taken seriously with respect to their philosophical and aesthetic import. As a consequence, the objective becomes that of enhancing the reader’s understanding of the lyric contexts in which Théophile’s scatological offerings situate themselves. Structurally, the reader sees how the poet’s libertine ceuvre is just that — an integrated work in which the various components correspond to one another to set forth a number of approaches from which the texts are to be read. These points of view are not always consistent, and Théophile cannot be thought of as writing in a sequential manner along the lines of devotional Baroque poets such as Jean de La Ceppède and Jean de Sponde. However, there is a tendency not to read these poems in their vulgar totality, and to overlook the formal and substantive unity in this category of Théophile’s work. The poet’s resistance to poetic and cultural standards takes a profane, if not pornographic form because it seeks to disgust and arouse while denigrating the self, the lyric other, and the reader. Théophile’s pornography makes no distinction between the erotic and scatological. The poet conflates sex and shit because they present a double form of protest to artistic and social decency while titillating and attacking the reader’s sensibilities. Examination of the repugnant gives way to a cathartic experience which yields an understanding of, if not ironic delight in, one’s own filthy nature.

Programming peculiarities in two cochlear implant users with superficial siderosis of the central nervous system

To report the audiological outcomes of cochlear implantation in two patients with severe to profound sensorineural hearing loss secondary to superficial siderosis of the CNS and discuss some programming peculiarities that were found in these cases. Retrospective review. Data concerning clinical presentation, diagnosis and audiological assessment pre- and post-implantation were collected of two patients with superficial siderosis of the CNS. Both patients showed good hearing thresholds but variable speech perception outcomes. One patient did not achieve open-set speech recognition, but the other achieved 70% speech recognition in quiet. Electrical compound action potentials could not be elicited in either patient. Map parameters showed the need for increased charge. Electrode impedances showed high longitudinal variability. The implants were fairly beneficial in restoring hearing and improving communication abilities although many reprogramming sessions have been required. The hurdle in programming was the need of frequent adjustments due to the physiologic variations in electrical discharges and neural conduction, besides the changes in the impedances. Patients diagnosed with superficial siderosis may achieve limited results in speech perception scores due to both cochlear and retrocochlear reasons. Careful counseling about the results must be given to the patients and their families before the cochlear implantation indication.

Fluorescence polarization assay, competitive enzyme-linked immunosorbent assay (ELISA-C) and indirect ELISA for the diagnosis of brucellosis in buffaloes (Bubalus bubalis)

The objective of the present study was to compare the performance of three serological tests for diagnosis of Brucella abortus infections in buffaloes (Bubalus bubalis). Serum samples collected from 696 adult females were submitted to the competitive enzyme-linked immunosorbent assay (ELISAC), (I-ELISA), fluorescence polarization test (FPA), 2-mercaptoethanol test (2-ME) and complement fixation test (CFT). The gold standard was the combination of CFT and 2-ME, considering as positive the reactors in both CFT and 2-ME, and as negative those non-reactors. ROC analyses were done for C-ELISA, I-ELISA and FPA and the Kappa agreement index were also calculated. The best combinations of relative sensitivity (SEr) and relative specificity (SPr) and Kappa were given by C-ELISA (96.9%, 99.1%, and 0.932, respectively) and FPA (92.2%, 97.6 and 0.836, respectively). The C-ELISA and FPA were the most promising confirmatory tests for the serological diagnosis of brucellosis in buffaloes, and for these tests, cut-off values for buffaloes may be the same as those used for bovines.

Patient with toxoplasmosis and glucose-6-phosphate dehydrogenase deficiency: a case report

Abstract Introduction Toxoplasmosis, a zoonotic protozoal disease caused by toxoplasma gondii, is prevalent throughout the world, affecting a large proportion of persons who usually have no symptoms. Glucose 6 phosphate dehydrogenase deficiency, an X-linked inherited disorder, is present in over 400 million people world wide. It is more common in tropical and subtropical countries and is one of the important causes of hemolytic anemia. Case presentation This case report relates the occurrence of the two diseases simultaneously in a child of five years old. Conclusion Patients with glucose-6-phosphate dehydrogenase deficiency are more susceptible to toxoplasmosis and this case report, reinforce the findings of this propensity and alert us for such possibility, what it is important, therefore, the treatment of toxoplasmosis can cause serious hemolysis in these patients.

Leg and arm lactate and substrate kinetics during exercise

[EN] To study the role of muscle mass and muscle activity on lactate and energy kinetics during exercise, whole body and limb lactate, glucose, and fatty acid fluxes were determined in six elite cross-country skiers during roller-skiing for 40 min with the diagonal stride (Continuous Arm + Leg) followed by 10 min of double poling and diagonal stride at 72-76% maximal O(2) uptake. A high lactate appearance rate (R(a), 184 +/- 17 micromol x kg(-1) x min(-1)) but a low arterial lactate concentration ( approximately 2.5 mmol/l) were observed during Continuous Arm + Leg despite a substantial net lactate release by the arm of approximately 2.1 mmol/min, which was balanced by a similar net lactate uptake by the leg. Whole body and limb lactate oxidation during Continuous Arm + Leg was approximately 45% at rest and approximately 95% of disappearance rate and limb lactate uptake, respectively. Limb lactate kinetics changed multiple times when exercise mode was changed. Whole body glucose and glycerol turnover was unchanged during the different skiing modes; however, limb net glucose uptake changed severalfold. In conclusion, the arterial lactate concentration can be maintained at a relatively low level despite high lactate R(a) during exercise with a large muscle mass because of the large capacity of active skeletal muscle to take up lactate, which is tightly correlated with lactate delivery. The limb lactate uptake during exercise is oxidized at rates far above resting oxygen consumption, implying that lactate uptake and subsequent oxidation are also dependent on an elevated metabolic rate. The relative contribution of whole body and limb lactate oxidation is between 20 and 30% of total carbohydrate oxidation at rest and during exercise under the various conditions. Skeletal muscle can change its limb net glucose uptake severalfold within minutes, causing a redistribution of the available glucose because whole body glucose turnover was unchanged.
