The Science of the Modern Kitchen.

The kitchen offers chemists an opportunity to cook up chemistry using everyday ingredients. This is the inspiration behind 'The Science of the Modern Kitchen', a chemistry course offered to non-science undergraduates.

Biochemical studies highlight determinants for metal selectivity in the Escherichia coli periplasmic solute binding protein NikA.

Nickel is an essential micronutrient for the survival of many microbes. On account of the toxicity of nickel and its scarcity in the environment, microbes have evolved specific systems for uptaking and delivering nickel to enzymes. NikA, the solute binding protein for the ATP-binding cassette (ABC) importer NikABCDE, plays a vital role in the nickel homeostasis of Escherichia coli by selectively binding nickel over other metals in the metabolically complex periplasm.

Identifying Phytochemicals from Biomedical Literature Utilizing Semantic Knowledge Sources.

Chemicals derived from plants (phytochemicals) are major concepts of interest in the study of medicinal plants. To date, efforts to catalogue and organize phytochemical knowledge have resorted to manual approaches. This study explored the potential to leverage publicly accessible semantic knowledge sources for identifying possible phytochemicals.

Harnessing Biomedical Natural Language Processing Tools to Identify Medicinal Plant Knowledge from Historical Texts.

The growing amount of data describing historical medicinal uses of plants from digitization efforts provides the opportunity to develop systematic approaches for identifying potential plant-based therapies. However, the task of cataloguing plant use information from natural language text is a challenging task for ethnobotanists. To date, there have been only limited adoption of informatics approaches used for supporting the identification of ethnobotanical information associated with medicinal uses.

Identifying Plant-Human Disease Associations in Biomedical Literature: A Case Study.

The impact of ethnobotanical data from surveys of traditional medicinal uses ofplants can be enhanced through the validation of biomedical knowledge that may be embedded in literature. This study aimed to explore the use of informatics approaches, including natural language processing and terminology resources, for extracting and comparing ethnobotanical leads from biomedical literature indexed in MEDLINE. Using ethnobotanical data for plant species described in Primary Health Care Manuals of the Micronesian islands of Palau and Pohnpei, the results of this study were done relative to disease concepts from the "Mental, Behavioral And Neurodevelopmental Disorders " ICD-9-CM category.

Human-induced dwarfing of Himalayan snow lotus, Saussurea laniceps (Asteraceae).

Because evolutionary processes such as genetic drift and natural selection play a crucial role in determining the response that species will have to human-induced disturbances, there is increasing interest in the evolutionary aspects of conservation biology. Harvesting select individuals in natural plant populations can bring about unforeseen impacts that may negatively affect fitness. We analyzed how human harvesting affects two congeners known as snow lotus.
