The timing of life-history events in a changing climate. (1/3)
Although empirical and theoretical studies suggest that climate influences the timing of life-history events in animals and plants, correlations between climate and the timing of events such as egg-laying, migration or flowering do not reveal the mechanisms by which natural selection operates on life-history events. We present a general autoregressive model of the timing of life-history events in relation to variation in global climate that, like autoregressive models of population dynamics, allows for a more mechanistic understanding of the roles of climate, resources and competition. We applied the model to data on 50 years of annual dates of first flowering by three species of plants in 26 populations covering 4 degrees of latitude in Norway. In agreement with earlier studies, plants in most populations and all three species bloomed earlier following warmer winters. Moreover, our model revealed that earlier blooming reflected increasing influences of resources and density-dependent population limitation under climatic warming. The insights available from the application of this model to phenological data in other taxa will contribute to our understanding of the roles of endogenous versus exogenous processes in the evolution of the timing of life-history events in a changing climate. (+info)Neuroprotective and antioxidant effects of the ethyl acetate fraction prepared from Tussilago farfara L. (2/3)
The flower buds of Tussilago farfara L. (Compositae) have been traditionally used in Oriental medicine for the treatment of bronchitis and asthma. The extract of T. farfara was reported to exhibit antiinflammatory actions by inhibiting arachidonic acid metabolism and nitric oxide (NO) production in lipopolysaccharide-activated macrophages. In the present study, we investigated the effects of the ethyl acetate (EA) fraction on various types of neuronal cell damage induced in primary cultured rat cortical cells. Its antioxidant activities were also evaluated by cell-free bioassays. We found that the EA fraction potently inhibited the neuronal damage induced by arachidonic acid. We also found that it significantly attenuated the neuronal damage induced by spermine NONOate, a stable NO generator. In addition, it inhibited the A(beta(25-35))-induced neurotoxicity and glutamate- or N-methyl-D-aspartic acid-induced excitotoxicity. It was found that the oxidative neuronal damage induced by H2O2, xanthine/xanthine oxidase, or Fe(2+)/ascorbic acid was also inhibited by the EA fraction. Furthermore, it was shown to inhibit lipid peroxidation initiated by Fe(2+)/ascorbic acid in rat brain homogenates, and scavenge DPPH radicals. This is the first demonstration of neuroprotective and antioxidant effects of T. farfara. Although complex mechanisms may be involved in the neuroprotective actions, T. farfara may be useful for the management of neurodegenerative disorders associated with inflammation, A(beta), excitotoxicity, and/or oxidative stress.

(+info)"Tussilago" is the genus name for a type of plant commonly known as coltsfoot. The term "Tussilago farfara" is its full botanical name. This plant has been used in traditional medicine for its anti-tussive (cough suppressant) and expectorant properties. However, it's important to note that recent studies have shown that this plant can contain toxic compounds, particularly in its leaves and roots, which can negatively affect the liver. Therefore, its use as a medicinal remedy is not generally recommended.
Pyrrolizidine alkaloids (PAs) are a group of naturally occurring chemical compounds found in various plants, particularly in the families Boraginaceae, Asteraceae, and Fabaceae. These compounds have a pyrrolizidine ring structure and can be toxic or carcinogenic to humans and animals. They can contaminate food and feed sources, leading to poisoning and health issues. Chronic exposure to PAs has been linked to liver damage, veno-occlusive disease, and cancer. It is important to avoid consumption of plants containing high levels of PAs and to monitor food and feed sources for PA contamination.
"Petasites" is a genus name in botany, which refers to a group of flowering plants in the family Asteraceae. While it may not have a direct medical definition, some species within this genus have been used in traditional medicine. For instance, Petasites hybridus (also known as butterbur) has been used in herbal medicine for treating migraines, allergies, and asthma. However, it's important to note that the use of these plants should be under the guidance of a healthcare professional, as they can have side effects and interact with certain medications.
I'm sorry for any confusion, but "Senecio" is not a medical term. It is actually the name of a genus of plants in the family Asteraceae, also known as the daisy or composite family. Some species of Senecio contain pyrrolizidine alkaloids, which can be toxic to livestock and potentially harmful to humans if ingested. However, there is no direct medical relevance of "Senecio" itself in the context of medical definitions.
"Taraxacum" is the scientific name for the plant species commonly known as dandelions. These are flowering plants that belong to the Asteraceae family and are native to Eurasia. The name "Taraxacum" comes from the Greek words "taraxos," meaning disorder, and "akos," meaning remedy, reflecting the historical use of dandelion leaves and roots as herbal medicine.
Dandelions have bright yellow flowers that turn into spherical seed heads, which are often blown away by the wind, scattering the seeds. All parts of the plant, including the leaves, flowers, and roots, can be used in various culinary and medicinal applications. Dandelion greens are rich in vitamins and minerals, while dandelion root tea is believed to have diuretic properties. However, it's important to note that the medical benefits of dandelions have not been extensively studied or proven by modern scientific research.
Asteraceae is a family of flowering plants commonly known as the daisy family or sunflower family. It is one of the largest and most diverse families of vascular plants, with over 1,900 genera and 32,000 species. The family includes a wide variety of plants, ranging from annual and perennial herbs to shrubs and trees.
The defining characteristic of Asteraceae is the presence of a unique type of inflorescence called a capitulum, which resembles a single flower but is actually composed of many small flowers (florets) arranged in a dense head. The florets are typically bisexual, with both male and female reproductive structures, and are radially symmetrical.
Asteraceae includes many economically important plants, such as sunflowers, daisies, artichokes, lettuce, chicory, and ragweed. Some species of Asteraceae are also used in traditional medicine and have been found to contain bioactive compounds with potential therapeutic uses.
It's worth noting that the taxonomy of this family has undergone significant revisions in recent years, and some genera and species have been moved to other families or renamed.
An encyclopedia is a comprehensive reference work containing articles on various topics, usually arranged in alphabetical order. In the context of medicine, a medical encyclopedia is a collection of articles that provide information about a wide range of medical topics, including diseases and conditions, treatments, tests, procedures, and anatomy and physiology. Medical encyclopedias may be published in print or electronic formats and are often used as a starting point for researching medical topics. They can provide reliable and accurate information on medical subjects, making them useful resources for healthcare professionals, students, and patients alike. Some well-known examples of medical encyclopedias include the Merck Manual and the Stedman's Medical Dictionary.
