Environmental pollution with chromium(Cr) is harmful to humans, animals and plants, while in plants it causes diminished growth,anatomical alterations and death. In the present study, the potential value of marigold(Tagetes erecta) in the phytoremediation of Cr has been investigated. The randomized experimental design involved the exposure of plants to nutrient solutions containing 0.00,0.04, 0.08, 0.12, 0.16 or 0.24 mmol L^(-1)Cr(Ⅲ). Chromium toxicity was observed at Cr(Ⅲ) concentrations ≥ 0.12 mmol L^(-1) as demonstrated by diminished growth of the aerial parts and reduced density of the root system. Increasing Cr(Ⅲ) concentrations in the nutrient solution resulted in a higher bioaccumulation of total Cr in the tissues, although translocation from roots to aerial parts was not efficient(maximum value of 25% at 0.12 mmol L^(-1)Cr(Ⅲ)). The Cr bioaccumulation was up to 11-fold greater in roots than in the aerial parts. Tagetes erecta exhibited leaf plasticity when exposed to Cr, indicating the existence of a tolerance mechanism to Cr in this species. Chromium caused a reduction in xilem vases, resulting in a plastic effect in T. erecta leaves that increased the metal tolerance in culture solution. Tagetes spp. are potential Cr hyperaccumulators; at Cr(Ⅲ) concentrations up to 0.12 mmol L^(-1), the plants accumulated levels above that proposed for hyperaccumulators and still maintained a considerable growth and even flourished. However, this study was conducted in nutrient solution, and studies on species confirmation as Cr hyperaccumulator should be conducted in soils for further clarification.

Telomere Maintenance Mechanisms: Prognostic and Therapeutic Implications for the Pathologist and Oncologist

引用

Open Journal of Pathology 2013年第1期3卷 10-20页

作者： Noelyn A. Hung Howard Hsia janice A. Royds Tania L. Slatter Department of Pathology Dunedin School of Medicine University of Otago Dunedin New Zealand

In neoplasia, telomere maintenance mechanisms (TMMs) can be prognostic and may direct therapy in the future. Two types of TMM, telomerase and recombination-based alternative lengthening of telomeres (ALT), result in four prognostic tumor groups when they occur individually, in combination, or in mutual absence. Correct designation of the TMM therefore requires an assessment of telomerase activity and for ALT telomere length distribution and ALT associated promyelocytic leukaemia protein (PML) bodies (APBs). The four groups are associated with differing prognoses that are dependent on the tumor type. As TMM inhibitors are developed, oncologists will require that pathologists determine the TMM, and the treatments will differ accordingly. Furthermore, any anti-TMM therapy administered has the potential to selectively change the TMM used by a tumor, necessitating reassessment of the therapeutic strategy. Herein, we review the telomere maintenance mechanisms, the current diagnostic measures and their utility as prognostic markers in the clinical setting.

Lane changing and merging occurs more frequently in work zones than other roadway conditions due to mandatory lane changes that occur in work zones with lane *** lane changes are also performed in work zones under conditions where drivers respond to signage,speed reduction,drivers’aggressiveness,entering and exiting work zone area,or avoiding slow moving or heavy *** driver behavior and particularly lane changing within and entering the work zone area can be utilized to better design and operate safe work *** overall objective for this research is to develop logistic regression model to identify factors that influence drivers’lane changing behavior in order to improve work zone *** vehicle type,original lane average speed and target lane volume were found to be a significant factor influencing lane changes in the work zone.
