Use of reference in the narratives of Kurdish-Persian bilingual children

This study investigates some of the differences and similarities between Kurdish-Persian bilinguals and Persian monolinguals with respect to the use of referring expressions in spoken narratives. The narratives were elicited from 36 participants, consisting of 24 bilinguals (groups 1 and 2) and 12 monolinguals (group 3) in the first four grades of primary school using the Mayer’s (1969) book ‘Frog, where are you?’. The results have revealed that group 1 (bilingual told the story in Kurdish) used definite noun phrases most frequently followed by zero anaphors, indefinite noun phrases and pronouns. Group 2 who narrated the story in Persian produced definite nouns most frequently followed by pronouns, zero anaphors and indefinite noun phrases and group 3 (Persian monolinguals) employed definite noun phrases followed by zero anaphors, pronouns, and indefinite noun phrases. The significant difference between groups 1 and 2 and groups 2 and 3 has been in indefinite noun phrases and between groups 1 and 3 in the use of pronouns. One reason is that children universally apply similar strategies regardless of their first language (Berman, 2001). The conclusion is that some of the differences are due to the difference in the structure between Persian and the dialects of Kurdish.

Prospective study of soft tissue contour changes following chin bone graft harvesting

This study sought to evaluate changes in the soft tissue contour after chin bone graft harvesting. Thirty selected patients underwent chin bone graft harvesting and evaluations were made using lateral cephalograms preoperatively and postoperatively at 30 and 180 days. Fixed points and lines were established on cephalometric tracings and used to measure the selected vertical and sagittal parameters. Results showed statistically significant alterations to the vertical position values of the vermilion (V-VPV) which increased from 9.70 to 11.01 and the exposure of lower incisors (V-ELI) which increased from 1.85 to 3.5, showing an increase in their distance from the plane of reference and a lowering of their position, the clinical equivalent of a labial ptosis condition. None of the sagittal parameters analysed showed any statistically significant variation in the final evaluation. The study concluded that the alterations to patients' soft tissue contours resulted mainly from failure to ensure precise reattachment of the mentalis muscles and identified the need for further investigation of that aspect.

Identification of reference genes for expression analysis by real-time quantitative PCR in drought-stressed soybean

O objetivo deste trabalho foi validar, pela técnica de PCR quantitativo em tempo real (RT-qPCR) genes para serem utilizados como referência em estudos de expressão gênica em soja, em ensaios de estresse hídrico. Foram avaliados quatro genes comumente utilizados em soja: Gmβ-actin, GmGAPDH, GmLectin e GmRNAr18S. O RNA total foi extraído de seis amostras: três amostras de raízes em sistema de hidroponia com diferentes intensidades de déficit hídrico (0, 25, 50, 75 e 100 minutos de estresse hídrico), e três amostras de folhas de plantas cultivadas em areia com diferentes umidades do solo (15, 5 e 2,5% de umidade gravimétrica). Os dados brutos do intervalo cycle threshold (Ct) foram analisados, e a eficiência de cada iniciador foi calculada para uma analise da Ct entre as diferentes amostras. A aplicação do programa GeNorm foi utilizada para a avaliação dos melhores genes de referência, de acordo com a estabilidade. O GmGAPDH foi o gene menos estável, com o maior valor médio de estabilidade de expressão (M), e os genes mais estáveis, com menor valor de M, foram o Gmβ-actin e GmRNAr18S, tanto nas amostras de raízes como nas de folhas. Estes genes podem ser usados em RT-qPCR como gens de referência para análises de expressão gênica.
