Henry Jeanneret was a pioneer Australian dentist, perhaps the first in this country to promote the discipline of dentistry as distinct from medicine and general surgery. This profile describes his early life and training, his emigration to Australia, his clinical practice in Sydney and in Van Diemen's Land, and his contributions to natural history, particularly in the field of botany.  相似文献

The ambitious idea of using a short piece of DNA for large-scale species identification (DNA barcoding) is already a powerful tool for scientists and the application of this standard technique seems promising in a range of fields including forensic genetics. While DNA barcoding enjoyed a remarkable success for animal identification through cytochrome c oxidase I (COI) analysis, the attempts to identify a single barcode for plants remained a vain hope for a longtime. From the beginning, the Consortium for the Barcode of Life (CBOL) showed a lack of agreement on a core plant barcode, reflecting the diversity of viewpoints. Different research groups advocated various markers with divergent set of criteria until the recent publication by the CBOL–Plant Working Group. After a four-year effort, in 2009 the International Team concluded to agree on standard markers promoting a multilocus solution (rbcL and matK), with 70–75% of discrimination to the species level. In 2009 our group firstly proposed the broad application of DNA barcoding principles as a tool for identification of trace botanical evidence through the analysis of two chloroplast loci (trnH-psbA and trnL-trnF) in plant species belonging to local flora. Difficulties and drawbacks that were encountered included a poor coverage of species in specific databases and the lack of authenticated reference sequences for the selected markers. Successful preliminary results were obtained providing an approach to progressively identify unknown plant specimens to a given taxonomic rank, usable by any non-specialist botanist or in case of a shortage of taxonomic expertise. Now we considered mandatory to update and to compare our previous findings with the new selected plastid markers (matK + rbcL), taking into account forensic requirements.Features of all the four loci (the two previously analyzed trnH-psbA + trnL-trnF and matK + rbcL) were compared singly and in multilocus solutions to assess the most suitable combination for forensic botany.Based on obtained results, we recommend the adoption of a two-locus combination with rbcL + trnH-psbA plastid markers, which currently best satisfies forensic needs for botanical species identification.  相似文献

The ubiquitous presence of plant species makes forensic botany useful for many criminal cases. Particularly, bryophytes are useful for forensic investigations because many of them are clonal and largely distributed. Bryophyte shoots can easily become attached to shoes and clothes and it is possible to be found on footwear, providing links between crime scene and individuals. We report a case of suicide of a young girl happened in Siena, Tuscany, Italia. The cause of traumatic injuries could be ascribed to suicide, to homicide, or to accident. In absence of eyewitnesses who could testify the dynamics of the event, the crime scene investigation was fundamental to clarify the accident. During the scene analysis, some fragments of Tortula muralis Hedw. and Bryum capillare Hedw were found. The fragments were analyzed by a bryologists in order to compare them with the moss present on the stairs that the victim used immediately before the death. The analysis of these bryophytes found at the crime scene allowed to reconstruct the accident. Even if this evidence, of course, is circumstantial, it can be useful in forensic cases, together with the other evidences, to reconstruct the dynamics of events.  相似文献

开放式教学在药用植物学与生药学实验教学中的应用   总被引:1,自引:0,他引:1  
开放式教学是以学生主动探索、发现、获取知识为目的的一种教学方式,它通过教学系统和社会系统的结合,实现理论知识和实践知识之间的融合。在药用植物学和生药学实验教学的教学环境、教学内容、墼学过程和评价体系中引入开放式教学,使枯燥、抽象的专业知识变得生动、具体,从而激发学生的学习兴趣和主动性,巩固学生所学的专业理论知识,有利于培养学生的合作能力、实践能力和创新能力。  相似文献

Plants from the genus Trifolium have been used in traditional medicine by many cultures. In Turkish folk medicine, for example, some Trifolium species are used for their expectorant, analgesic, antiseptic properties and also to treat rheumatic aches. Some species are also grown as pasture crops for animals in the Mediterranean. The high quercetin concentration and soyasaponin occurrence make the seeds of some Trifolium species a potential source of health beneficial phytochemicals for use in human nutrition. However, Trifolium pratense has also gained popularity due to research into its use for the treatment for menopausal symptoms. This paper provides an overview of the phytochemical and pharmacological profile of Trifolium species. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献
