Signaled two-way avoidance learning using electrical stimulation of the inferior colliculus as negative reinforcement: effects of visual and auditory cues as warning stimuli

The inferior colliculus is a primary relay for the processing of auditory information in the brainstem. The inferior colliculus is also part of the so-called brain aversion system as animals learn to switch off the electrical stimulation of this structure. The purpose of the present study was to determine whether associative learning occurs between aversion induced by electrical stimulation of the inferior colliculus and visual and auditory warning stimuli. Rats implanted with electrodes into the central nucleus of the inferior colliculus were placed inside an open-field and thresholds for the escape response to electrical stimulation of the inferior colliculus were determined. The rats were then placed inside a shuttle-box and submitted to a two-way avoidance paradigm. Electrical stimulation of the inferior colliculus at the escape threshold (98.12 ± 6.15 (A, peak-to-peak) was used as negative reinforcement and light or tone as the warning stimulus. Each session consisted of 50 trials and was divided into two segments of 25 trials in order to determine the learning rate of the animals during the sessions. The rats learned to avoid the inferior colliculus stimulation when light was used as the warning stimulus (13.25 ± 0.60 s and 8.63 ± 0.93 s for latencies and 12.5 ± 2.04 and 19.62 ± 1.65 for frequencies in the first and second halves of the sessions, respectively, P<0.01 in both cases). No significant changes in latencies (14.75 ± 1.63 and 12.75 ± 1.44 s) or frequencies of responses (8.75 ± 1.20 and 11.25 ± 1.13) were seen when tone was used as the warning stimulus (P>0.05 in both cases). Taken together, the present results suggest that rats learn to avoid the inferior colliculus stimulation when light is used as the warning stimulus. However, this learning process does not occur when the neutral stimulus used is an acoustic one. Electrical stimulation of the inferior colliculus may disturb the signal transmission of the stimulus to be conditioned from the inferior colliculus to higher brain structures such as amygdala

Streptococcus mutans GlnK protein: an unusual PII family member

Streptococcus mutans is a Gram-positive bacterium present in the oral cavity, and is considered to be one of the leading causes of dental caries. S. mutans has a glnK gene, which codes for a PII-like protein that is possibly involved in the integration of carbon, nitrogen and energy metabolism in several organisms. To characterize the GlnK protein of S. mutans, the glnK gene was amplified by PCR, and cloned into the expression vectors pET29a(+) and pET28b(+). The native GlnK-Sm was purified by anion exchange (Q-Sepharose) and affinity (Hi-Trap Heparin) chromatography. The GlnK-His-Sm protein was purified using a Hi-Trap Chelating-Ni2+ column. The molecular mass of the GlnK-His-Sm proteins was 85 kDa as determined by gel filtration, indicating that this protein is a hexamer in solution. The GlnK-His-Sm protein is not uridylylated by the Escherichia coli GlnD protein. The activities of the GlnK-Sm and GlnK-His-Sm proteins were assayed in E. coli constitutively expressing the Klebsiella pneumoniae nifLA operon. In K. pneumoniae, NifL inhibits NifA activity in the presence of high ammonium levels and the GlnK protein is required to reduce the inhibition of NifL in the presence of low ammonium levels. The GlnK-Sm protein was unable to reduce NifL inhibition of NifA protein. Surprisingly, the GlnK-His-Sm protein was able to partially reduce NifL inhibition of the NifA protein under nitrogen-limiting conditions, in a manner similar to the GlnK protein of E. coli. These results suggested that S. mutans GlnK is functionally different from E. coli PII proteins.

Disfunção do trato urinário inferior: um diagnóstico comum na prática pediátrica

Disfunção do trato urinário inferior indica uma função anormal do trato urinário inferior para a idade da criança, que pode levar à perda da capacidade coordenada de armazenamento e eliminação de urina. É uma entidade comum em crianças, embora subdiagnosticada na prática clínica, e que, além de representar um risco para o trato urinário superior, causa um constrangimento emocional aos pais e às crianças, devido à incontinência urinária e à frustração em lidar com o problema. A aquisição da continência urinária diurna ocorre na maioria das crianças até os 4 anos e a noturna até os 5 anos de idade. Após esta idade, a incontinência urinária torna-se um problema social. Apesar da importância clínica, muitas vezes, os pais desconhecem os sintomas dessa disfunção. Esse artigo tem como objetivo abordar os principais aspectos relacionados ao diagnóstico dessa disfunção.

Impacto de uma abordagem interdisciplinar em crianças e adolescentes com disfunção do trato urinário inferior (DTUI)

Introdução: A disfunção do trato urinário inferior (DTUI) corresponde a alterações no enchimento ou esvaziamento de urina de causas neurogênicas, anatômicas e funcionais. Objetivo: Avaliar o impacto do tratamento em crianças e adolescentes com DTUI. Métodos: Coorte histórica de 15 anos de seguimento com participação de 192 pacientes (123F, 69M) com idade inicial de 0,1 a 16,8 anos, analisados à admissão (T0) e ao final do seguimento (T1). A maioria dos pacientes era do grupo neurológico (60,4%). O tratamento instituído foi a uroterapia com intervenção comportamental e cognitiva, micção de hora marcada, hidratação oral, dieta laxativa, biofeedback, eletroestimulação sacral, cateterismo vesical intermitente limpo (CIL), terapia anticolinérgica, enema retal, tratamento da infecção do trato urinário (ITU) e, nos casos refratários, procedimentos cirúrgicos, tais como a derivação urinária continente e incontinente (vesicostomia), ampliação vesical e conduto para a realização do enema anterógrado cólico. Resultados: Os principais sintomas foram incontinência urinária diurna (82,3%), enurese noturna não monossintomática (78,6%), incontinência fecal (54,2%) e constipação intestinal (47,9%). Detectou-se redução significativa da infecção do trato urinário (p = 0,0027), da incontinência urinária diurna (p < 0,001), da enurese noturna (p < 0,001), da incontinência fecal (p = 0,010) e do refluxo vesicoureteral (p = 0,01). Houve aumento significativo no uso do CIL (p = 0,021), da terapia com anticolinérgico (p < 0,001) e diminuição da quimioprofilaxia (p < 0,001). Conclusão: Este estudo mostrou que o tratamento da DTUI na criança deve ser individualizado, além de requerer uma monitorização constante dos parâmetros clínicos, laboratoriais e de imagem, para minimizar o risco de lesão renal.

Christian Church member at pulpit; Chapman College Chapel, Orange, California

Chapman College Chapel, Orange, California. The wooden-shingled church, constructed in 1909 for the congregation of Trinity Episcopal Church, is located on the northeast corner of East Maple Avenue and North Grand Street. Chapman College (now Chapman University) purchased the church for their chapel when the congregation moved to a new church on Canal Street.
