Ritzel, Rodrigo Agne,Berwig, Luana Cristina,Silva, Ana Maria Toniolo da,Corrêa, Eliane Castilhos Rodrigues
International Archives of Otorhinolaryngology , 2012,
Abstract: Introduction: Hyperplasia of the pharyngeal tonsil is one of the main causes of mouth breathing, and accurate diagnosis of this alteration is important for proper therapeutic planning. Therefore, studies have been conducted in order to provide information regarding the procedures that can be used for the diagnosis of pharyngeal obstruction. Objective: To verify the correlation between nasopharyngoscopy and cephalometric examinations in the diagnosis of pharyngeal tonsil hyperplasia. Method: This was a cross-sectional, clinical, experimental, and quantitative study. Fifty-five children took part in this study, 30 girls and 25 boys, aged between 7 and 11 years. The children underwent nasofibropharyngoscopic and cephalometric evaluation to determine the grade of nasopharyngeal obstruction. The Spearman's rank correlation coefficient at the 5% significance level was used to verify the correlation between these exams. Results: In the nasopharyngoscopy evaluation, most children showed grade 2 and 3 hyperplasia of the pharyngeal tonsil, which was followed by grade 1. In the cephalometry assessment, most children showed grade 1 hyperplasia of the pharyngeal tonsil, which was followed by grade 2. A statistically significant regular positive correlation was observed between the exams. Conclusion: It was concluded that the evaluation of the pharyngeal tonsil hyperplasia could be carried out by fiber optic nasopharyngoscopy and cephalometry, as these examinations were regularly correlated. However, it was found that cephalometry tended to underestimate the size of the pharyngeal tonsil relative to nasopharyngoscopy.

Abstract: Gamma-glutamylcysteine synthetase deficiency (OMIM #230450)Glutamate-cysteine ligase deficiencyGamma-glutamylcysteine synthetase deficiency is a very rare autosomal recessive disease characterized by hemolytic anemia, and, in some cases, by neurological symptoms. The diagnosis is established by:? Low activity of gamma-glutamylcysteine synthetase in red blood cells, leukocytes and/or cultured skin fibroblasts.? Low levels of glutathione and gamma-glutamylcysteine in red blood cells and/or cultured skin fibroblasts.? Presence of mutation(s) in the gamma-glutamylcysteine synthetase genes. The patients whose results have been published have had homozygous mutations in the gene encoding the heavy subunit of the enzyme.In red blood cells heterozygous carriers have an enzyme activity of about 50% of the normal mean and normal levels of glutathione [1].Gamma-glutamylcysteine synthetase deficiency is very rare disease. Nine patients in seven families have been reported worldwide (USA, Germany, Japan, The Netherlands, Poland, and Spain).All patients with gamma-glutamylcysteine synthetase deficiency have had hemolytic anemia, usually rather mild [1-8]. In addition, two siblings also had spinocerebellar degeneration, peripheral neuropathy, myopathy and aminoaciduria [3,8]. Treatment with sulfonamide precipitated psychosis and pronounced hemolytic anemia in one of these siblings. One patient was reported to have learning disability with dyslexia and was also thought to be mentally retarded [5], and another had delayed psychomotor development and progressive sensory neuropathy of lower extremities, ataxia, hyperreflexia, dysarthria, and a peculiar gait suggestive of spinocerebellar degeneration [2]. Other symptoms found in patients with γ-glutamylcysteine synthetase deficiency are transient jaundice, reticulocytosis, and hepatosplenomegaly.Gamma-glutamylcysteine synthetase catalyzes the first and rate-limiting step in the synthesis of glutathione (GSH) (Figure 1) [9].

Strategic versus Ad-hoc Corporate Social Performance: An Analysis of CSP Maturity and Its Relationship to Corporate Financial Performance
Vida Skudiene,Christine McClatchey,Agne Kancleryte
Journal of Management and Sustainability , 2012, DOI: 10.5539/jms.v3n1p16
Abstract: This paper extends empirical research that examines the Corporate Social Performance (CSP)-Corporate Financial Performance (CFP) relationship. Previous studies display mixed findings with no unified evidence regarding the CSP-CFP relationship’s direction or impact. We introduce the concepts of strategic CSP and ad-hoc CSP, which we collectively term “CSP maturity.” Using panel data on 86 large European banks and insurance companies, we investigate whether there is a relationship between a company’s financial performance (CFP) and CSP maturity and, if a relationship is present, its direction and causality. Correlation analysis suggests CSP maturity and CFP are negatively related to one another; independent sample t-tests show statistically significant different means of ROA and ROS for companies engaged in strategic and ad-hoc CSP. Ad-hoc companies were on average associated with better ROA and ROS. No significant difference was present for ROE. In contrast, regression analysis did not show a relationship between CSP maturity and CFP, suggesting CSP maturity does not have an impact on CFP nor can CFP be used to explain CSP maturity. The results of this study may be limited in their generalizations because the data includes 2007-2008; a period of time the global economy experienced a major recession.
A New Approach for Assessment of Mental Architecture: Repeated Tagging
Aire Raidvee, Agne P?lder, Jüri Allik
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0029667
Abstract: A new approach to the study of a relatively neglected property of mental architecture—whether and when the already-processed elements are separated from the to-be-processed elements—is proposed. The process of numerical proportion discrimination between two sets of elements defined either by color or by orientation can be described as sampling with or without replacement (characterized by binomial or hypergeometric probability distributions respectively) depending on the possibility to tag an element once or repeatedly. All empirical psychometric functions were approximated by a theoretical model showing that the ability to keep track of the already tagged elements is not an inflexible part of the mental architecture but rather an individually variable strategy which also depends on conspicuity of perceptual attributes. Strong evidence is provided that in a considerable number of trials, observers tagged the same element repeatedly which can only be done serially at two separate time moments.
Variable coordination of cotranscribed genes in Escherichia coli following antisense repression

BMC Microbiology , 2006, DOI: 10.1186/1471-2180-6-97
Abstract: To examine the effects of antisense inhibition on cotranscribed genes, we constructed a plasmid expressing the two reporter genes gfp and DsRed as one transcriptional unit. Incubation with antisense peptide nucleic acid (PNA) targeted to the mRNA start codon region of either the upstream gfp or the downstream DsRed gene resulted in a complete expression discoordination from this artificial construct. The same approach was applied to the three cotranscribed genes in the endogenously expressed lac-operon (lacZ, Y and A) and partial downstream expression coordination was seen when the lacZ start codon was targeted with antisense PNA. Targeting the lacY mRNA start codon region showed no effect on the upstream lacZ gene expression whereas expression from the downstream lacA gene was affected as strongly as the lacY gene. Determination of lacZ and lacY mRNA levels revealed a pattern of reduction that was similar to the Lac-proteins, indicating a relation between translation inhibition and mRNA degradation as a response to antisense PNA treatment.The results show that antisense mediated repression of genes within operons affect cotranscribed genes to a variable degree. Target transcript stability appears to be closely related to inhibition of translation and presumably depends on translating ribosomes protecting the mRNA from intrinsic decay mechanisms. Therefore, for genes within operons and clusters it is likely that the nature of the target transcript will determine the inhibitory effects on cotranscribed genes. Consequently, no simple and specific methods for expression control of a single gene within polycistronic operons are available, and a thorough understanding of mRNA regulation and stability is required to understand the results from both knock-down and knock-out methods used in bacteria.Antisense agents are useful for functional genomics in bacteria as they can down-regulate expression of specific genes by binding mRNA and inhibit translation. As antisense agen
