Cadmium Accumulation in Tomato Cultivars and Its Effect on Expression of Metal Transport-Related Genes

Cadmium (Cd) content was quantified in the shoot of six tomato cultivars and the Cd effect on the expression of LeNRAMP3, LeFER, LeIRT1 and LeNRAMP1 was evaluated. The six tomato cultivars accumulated high Cd concentrations and were able to transport Cd to the fruits. Among the evaluated genes, the Cd-induced level of LeFER expression appeared to provide an evidence regarding the capacity of foliar Cd accumulation in tomato. The results indicate that tomato represents a possible pathway for Cd entry into the food chain and an attractive model organism for the elucidation of the mechanisms involved in Cd accumulation.     

INSECTICIDE-TREATED BED NETS IN ROND?NIA,BRAZIL: EVALUATION OF THEIR IMPACT ON MALARIA CONTROL

Mosquito nets treated with long-lasting insecticide (LLINs), when used in compliance with guidelines of the World Health Organization, may be effective for malaria vector control. In 2012, approximately 150,000 LLINs were installed in nine municipalities in the state of Rondônia. However, no studies have assessed their impact on the reduction of malaria incidence. This study analyzed secondary data of malaria incidence, in order to assess the impact of LLINs on the annual parasite incidence (API). The results showed no statistically significant differences in API one year after LLIN installation when compared to municipalities without LLINs. The adoption of measures for malaria vector control should be associated with epidemiological studies and evaluations of their use and efficiency, with the aim of offering convincing advantages that justify their implementation and limit malaria infection in the Amazon Region.

Accuracy and reliability of linear measurements using 3-dimensional computed tomographic imaging software for Le Fort I Osteotomy

Our purpose was to compare the accuracy and reliability of linear measurements for Le Fort I osteotomy using volume rendering software. We studied 11 dried skulls and used cone-beam computed tomography (CT) to generate 3-dimensional images. Linear measurements were based on craniometric anatomical landmarks that were predefined as specifically used for Le Fort I osteotomy, and identified twice each by 2 radiologists, independently, using Dolphin imaging version 11.5.04.35. A third examiner then made physical measurements using digital calipers. There was a significant difference between Dolphin imaging and the gold standard, particularly in the pterygoid process. The largest difference was 1.85 mm (LLpPtg L). The mean differences between the physical and the 3-dimensional linear measurements ranged from −0.01 to 1.12 mm for examiner 1, and 0 to 1.85 mm for examiner 2. Interexaminer analysis ranged from 0.51 to 0.93. Intraexaminer correlation coefficients ranged from 0.81 to 0.96 and 0.57 to 0.92, for examiners 1 and 2, respectively. We conclude that the Dolphin imaging should be used sparingly during Le Fort I osteotomy.
