Relationship between Helicobacter pylori detection and an increased risk of infection in childhood
Venerando, R;Rasmussen, LT;de Labio, RW;Gatti, LL;Francisco, O;Viani, GA;Rivera, LML;Pay?o, SLM;
Journal of Venomous Animals and Toxins including Tropical Diseases , 2012, DOI: 10.1590/S1678-91992012000400004
Abstract: the risk of developing gastric cancer is believed to be related to differences among helicobacter pylori strains and the inflammatory responses mediated by host genetic factors. h. pylori infection is acquired at an early age and in the absence of appropriate antibiotic therapy, it generally persists for life. tp53 gene regulates the transcription of several cytokines and chemokines involved in innate immunity and its action may be influenced by the presence of different h. pylori strains. the present study aimed to detect h. pylori in pediatric patients, to access tp53 polymorphism at codon 72 and to correlate such findings with age and histopathological results. three hundred and forty-two patients were analyzed. dna from their gastric biopsies was extracted and the detection of h. pylori was performed through polymerase chain reaction assays, urease test and histopathologic examination. allelic discrimination of snp rs1042522 (tp53) was performed by real-time polymerase chain reaction. our results suggest a possible relationship between the presence of h. pylori and chronic gastritis in children and young patients, and showed a significant association between ageing and positivity for h. pylori. it was verified that patients aged < 10 years were 1.3 times more likely to have infection by h. pylori when compared with those aged > 10 years. finally, no association was found between tp53 polymorphisms and the presence of h. pylori.

Journal of Venomous Animals and Toxins including Tropical Diseases , 2012, DOI: 10.1590/S1678-91992012000200008
Abstract: helicobacter pylori, a gram-negative bacterium, possesses two important virulence factors: the vacuolating toxin (vaca), and the cytotoxin-associated gene product (caga). the aim of the present study was to evaluate the presence of h. pylori in the stomach and oral cavity of humans and compare the caga and vaca genotypes of h. pylori found in different samples (stomach, saliva and dental plaque) from the same patient. gastric biopsies, saliva and dental plaques were obtained from 62 dyspeptic adults. dna was extracted and evaluated for the presence of h. pylori and the alleles caga and vaca. persons with gastritis had a higher frequency of h. pylori -positive samples in the stomach while positive samples from gastric biopsies were significantly correlated with those from the oral cavity. there was a high h. pylori frequency in patients while the caga gene was associated with vaca s1 alleles in gastric biopsies. our results suggest a reservoir of the species in the oral cavity and that, in one patient, more than one h. pylori strain may exist in the saliva, dental plaque and stomach. we found a relationship between gastric infection and the bacterium in the oral cavity, with the cytotoxin genotype varying between saliva and dental plaque.
Variation of nitric oxide levels in imported Plasmodium falciparum malaria episodes
K De Sousa, MS Silva, LT Tavira
African Journal of Biotechnology , 2008,
Abstract: Nitric oxide (NO) has been recognized during the past two decades as one of the most versatile players in the immune system. Even though the molecular mechanisms responsible by the naturally acquired immunity against malaria are still to be clarified, the production of NO seems to play an important role as a marker for the severity of the disease. In this study we assess the level of nitric oxide in the serum of subjects exposed to malarial settings but who have not become clinically infected by plasmodia parasites. We conclude that NO is in fact a marker of clinical infections but cannot be used as an indicator of the disease’s severity.

Tavares, Elaine Lara Mendes;Labio, Roberto Badra de;Martins, Regina Helena Garcia;
Brazilian Journal of Otorhinolaryngology , 2010, DOI: 10.1590/S1808-86942010000400013
Abstract: acoustic vocal analysis is a simple and fast method that allows to differentiate normal from changed voices. there are few studies that analyze normal acoustic vocal parameters at different age ranges in children. aims: to establish normative acoustic parameters of children's voice aged 4 to 12 years. methods: two hundred and forty children were divided into four sub-groups by age: g1 (n-60; 4-5 years), g2 (n-60; 6-7 years), g3 (n-60; 8-9 years) and g4 (n-60; 10-12 years). the children's parents answered a questionnaire and the children were submitted to auditory acuity evaluation (assessment of transient otoacoustic emissions), acoustic vocal analyses, otorhinolaryngological and videolaryngoscopy exams. results: the normal values for the acoustic vocal parameters studied were established according to age range and gender. as age increased, there was a decrease of f0 and apq and an increased in spi with statistical difference of these parameters. the vocal parameters did not differ between genders until the age of 12. conclusions: the characterization of the normative vocal patterns of children is an important reference for future studies. some of the changes showed a direct relationship between age and a reduction of f0 and of apq, and increase in spi, with no difference between genders.

World Journal of Gastroenterology , 2008,
Abstract: AIM: To evaluate the prevalence and determined the common characteristics of patients diagnosed with non-alcoholic fatty liver disease (NAFLD) at the Philippine General Hospital, Manila, from January 1999 to December 2004.METHODS: NAFLD was diagnosed in 134 from a total of 1102 patients, based on clinical, ultrasonographic and/or histopathological findings. Patients with conditions associated with secondary NAFLD were excluded. Chart review was done to note demographics, co-morbid illnesses, physical characteristics, hepatomegaly, aspartate/alanine aminotransferase (AST/ALT) levels, albumin, lipid levels, alkaline phosphatase, prothrombin time, and partial thromboplastin time. Data obtained were analyzed using the statistical program SPSS version 10.RESULTS: Of the 134 patients included, 71% were female and 29% male. Mean patient age was 42.2 years. Sixty percent of patients were obese, 56% had hepatomegaly, and 69% had diabetes. AST levels were elevated in 45% of subjects and ALT levels in 64%.CONCLUSION: The prevalence of NAFLD at our institution was 12.2%. Patients diagnosed appear to be younger in age in contrast to previous studies. Female sex, obesity, elevated liver enzymes, and diabetes were characteristic features of our NAFLD patients, which is comparable to previous studies from other countries.

Estructura de medios espa oles escritos en Internet: Diario de Cádiz, la aventura cibernética de un periódico local
Dra. Aurora Labio Bernal
Revista Latina de Comunicación Social , 2000,
Abstract: El nacimiento de las versiones digitales de algunos medios de comunicación impresos planteó hace algunos a os un debate en torno al fin de la prensa escrita que hoy en día parece haber sido superado. A pesar de llevar poco tiempo de existencia, esta nueva forma de hacer periodismo se va consolidando cada vez con más fuerza en nuestro país y ya no sólo las cabeceras nacionales son las que se lanzan a la aventura electrónica, sino que también periódicos locales buscan su hueco en la red. Es el caso de Diario de Cádiz Digital que, nacido en el verano de 1998, ha logrado ya en 1999 el premio que anualmente concede la Asociación de Usuarios de Internet a la empresa que mejor introduce en su seno las posibilidades que la red de redes ofrece.

Abstract: twenty-seven carcasses of non-castrated confined goat kids, (18 ? boer + ? saanen and nine saanen) with slaughtered weight of 30.1 ± 0.27 kg were used to evaluate quantitative characteristics of the carcass and qualitative characteristics of the loin and shoulder. the animals were distributed in a completely randomized design in a 2 × 3 factorial arrangement (breed group × diet). the diets consisted of inclusion of dry yeast, as follows: soybean meal, soybean meal + dried yeast or dried yeast. the other ingredients of the diets were oat hay (30% dm), ground corn and mineral mixture. hot carcass weight, cold carcass weight, weight loss by cooling, true carcass yield and carcass compactness index were not influenced by the inclusion of dry yeast nor by racial group. saanen goats presented the highest carcass commercial yield of carcass, but they needed 15 days more to reach the slaughter weight. the cut yields were not affected, but a significant interaction for shoulder yield occurred. dry yeast and breed group did not influence the measurements of the loin, the muscle:bone ratio, the cooking losses, the shear force and composition. there was a significant interaction between the inclusion of dry yeast in the diets and the breed group for the muscle proportion on loin, which was higher in the ? boer + ? saanen group. for the shoulder, inclusion of dry yeast and breed group did not alter the proportions of muscle, fat, protein and ash. however, in saanen goats, the proportion of bone and moisture content were higher and total lipid content was lower. the ? boer + ? saanen groups showed higher precocity. dry yeast is an alternative protein source that can be included in diets for goat kids.

Abstract: the effects of inactive dry yeast (saccharomyces cerevisiae) from sugar cane were studied in 18 primiparus saanen dairy goats (51.07±1.43) on dry matter intake and digestibility, milk production and quality. animals were distributed in a completely randomized design during 90 days (from day 60 of milking). diets were composed of soybean meal; soybean meal + dry yeast; or dry yeast, as protein sources, and ground corn, mineral supplement and corn silage (40%). animals fed the dry yeast diet showed lower intake of dry matter (dm), organic matter (om), crude protein, ether extract and neutral detergent fiber. diets did not influence milk yield; however the milk production efficiency (kg of milk produced/kg of crude protein ingested) was better in goats fed the dry yeast diet. acidity, somatic cell counts and milk urea nitrogen values were not affected by treatments. animals fed the soybean + dry yeast diet had higher fat and total solids than those fed the dry yeast diet. the digestibility of dm, om and total carbohydrate was lower for soybean only and soybean + dry yeast diets. total digestible nutrients were higher for dry yeast and soy bean diets than soybean + dry yeast diet. dry yeast from sugar cane is a good alternative protein source for feeding lactating dairy goats and can be recommended because it maintains the production performance.
