Development of sample handling procedures for foods under USDA's National Food and Nutrient Analysis Program

The National Food and Nutrient Analysis Program (NFNAP) was implemented in 1997 to update and improve the quality of food composition data maintained by the United States Department of Agriculture (USDA). NFNAP was designed to sample and analyze frequently consumed foods in the U.S. food supply using statistically rigorous sampling plans, established sample handling procedures, and qualified analytical laboratories. Methods for careful handling of food samples from acquisition to analysis were developed to ensure the integrity of the samples and subsequent generation of accurate nutrient values. The infrastructure of NFNAP, under which over 1500 foods have been sampled, mandates tested sample handling protocols for a wide variety of foods. The majority of these foods were categorized into several major areas: (1) frozen foods; (2) fresh produce and/or highly perishable foods requiring refrigeration; (3) fast foods and prepared foods; (4) shelf-stable foods; (5) specialized study and non-retail (point of production) foods; and (6) foods from remote areas (e.g. American Indian reservations). This paper describes the sample handling approaches, from the collection and receipt of the food items to the preparation of the analytical samples, with emphasis on the strategies developed for those foods. It provides a foundation for developing sample handling protocols of foods to be analyzed under NFNAP and for other researchers working on similar projects.     

Ⅰ期前后路手术治疗下颈椎骨折脱位

目的 评价Ⅰ期前后路手术治疗下颈椎骨折脱位伴关节突绞锁的可行性和近期临床效果.方法 对27例下颈椎骨折脱位伴关节突绞锁的患者,Ⅰ期行后路复位和前路减压植骨内固定术,定期X线摄片观察损伤节段的稳定性和融合率,观察有无并发症发生,以ASIA分级判定脊髓功能的恢复情况.结果 随访6～32个月(平均21.5个月),27例患者均获得了完全复位,损伤节段稳定,颈椎高度和生理曲度维持良好,融合率为100%,内固定位置良好,无植骨块脱出或钢板、螺钉松动、断裂等并发症,脊髓功能平均提高1.4级,无一例患者出现神经症状加重.结论 Ⅰ期前后路手术治疗下颈椎骨折脱位伴关节突绞锁可获得满意的复位、彻底的减压和即刻稳定性的重建,有利于脊髓功能的恢复,近期临床疗效满意.     

论《消费者权益保护法》在解决医患纠纷中的法律适用

在实践中，医患关系已具备了消费关系的形式特征，把医疗、预防、保健、康复等行为纳入公民消费范围是未来趋势，这将更有利于保护公民的合法权益。

Accumulation of toxic metals (Pb and Cd) in the sea urchin Diadema aff. antillarum Philippi, 1845, in an oceanic island (Tenerife,Canary Islands)

This document shows the results obtained from a study on the concentration of toxic heavy metals in the internal tissue and exoskeleton of sea urchins, collected from their natural habitat. The levels of lead and cadmium were measured by Graphite Furnace Atomic Absorption Spectrometry. The mean concentrations of lead and cadmium in the internal tissue were 304.04 and 260.54 μg/kg respectively, whereas in the shell they were 185.02 and 142.48 μg/kg. We also performed a statistical analysis of the differences in the distribution of metals between their exoskeleton and their internal content, a correlation study of the metal content in internal tissue and shell and sampling areas, and a correlation study between the metal content and sample size. Since the sea urchin Diadema antillarum presents a wide range of variation in metal content, this study suggests that this species is an excellent bioindicator of heavy metal contamination. © 2009 Wiley Periodicals, Inc.
