Grindelia Nuda
''Grindelia squarrosa'', also known as a curly-top gumweed or curlycup gumweed, is a small North American biennial or short-lived perennial plant. Description ''G. squarrosa'' is a decumbent to erect, much-branched perennial herb or subshrub growing up to tall. The leaves are long, gray-green, crenate with each tooth having a yellow bump near its tip, and resinous. The plant produces numerous flower heads in open, branching arrays. The flower bract (involucre) is resinous and consists of multiple overlapping rows of phyllaries with tips that are strongly curled outward, sometimes curling back to form a circle. Each head usually contains 12–40 yellow ray flowers, though sometimes the rays are absent. These surround many small disc flowers. The plant blooms from July through late September. The brown seed is usually four-angled, with loose scales. Varieties *''Grindelia squarrosa'' var. ''quasiperennis'' *''Grindelia squarrosa'' var. ''serrulata'' *''Grindelia squarrosa ...

Frederick Traugott Pursh
Frederick Traugott Pursh (or Friedrich Traugott Pursch) (February 4, 1774 – July 11, 1820) was a German people, German–United States, American botanist. Born in Großenhain, Saxony, under the name Friedrich Traugott Pursh, he was educated at Dresden Botanical Gardens, and emigrated to the United States in 1799. From 1802 to 1805, he worked in Philadelphia as the botanical manager of the extensive gardens of William Hamilton, Esq., "The Woodlands (Philadelphia), The Woodlands." By 1805, he was working for Benjamin Smith Barton on a new Flora (publication), flora of North America, under whom he studied the plants collected on the Lewis and Clark Expedition. His work with Barton allowed him to travel farther afield. In 1805, he traveled south from Maryland to the Carolinas and, in 1806, he traveled north from the mountains of Pennsylvania to New Hampshire. He made both trips principally on foot, with only his dog and a gun, covering over three thousand miles each season. Barton' ...

Disturbance (ecology)
In ecology, a disturbance is a temporary change in environmental conditions that causes a pronounced change in an ecosystem. Disturbances often act quickly and with great effect, to alter the physical structure or arrangement of biotic and abiotic elements. A disturbance can also occur over a long period of time and can impact the biodiversity within an ecosystem. Major ecological disturbances may include fires, flooding, storms, insect outbreaks and trampling. Earthquakes, various types of volcanic eruptions, tsunami, firestorms, impact events, climate change, and the devastating effects of human impact on the environment (anthropogenic disturbances) such as clearcutting, forest clearing and the introduction of invasive species can be considered major disturbances. Not only invasive species can have a profound effect on an ecosystem, but also naturally occurring species can cause disturbance by their behavior. Disturbance forces can have profound immediate effects on ecosystem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheumatism
Rheumatism or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism". There is a close overlap between the term soft tissue disorder and rheumatism. Sometimes the term "soft tissue rheumatic disorders" is used to describe these conditions. The term "Rheumatic Diseases" is used in MeSH to refer to connective tissue disorders. The branch of medicine devoted to the diagnosis and therapy of rheumatism is called rheumatology. Types Many rheumatic disorders of chronic, intermittent pain (including joint pain, neck pain or back pain) have historically been caused by infectious diseases. Their etiology was unknown until the 20th century and not treatable. Postinfectious arthritis, also known as reactive art ...

Kidney
The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains on ...

Hispanos Of New Mexico
The Hispanos of New Mexico, also known as Neomexicanos ( es, Neomexicano) or Nuevomexicanos, are Hispanic residents originating in the historical region of Santa Fe de Nuevo México, today the US state of New Mexico (''Nuevo México''), southern Colorado, and other parts of the Southwestern United States including Arizona, Nevada, Texas, and Utah. They are descended from Oasisamerica groups and the settlers of the Viceroyalty of New Spain, the First Mexican Empire and Republic, the Centralist Republic of Mexico, and the New Mexico Territory. The descendants of these New Mexican settlers make up an ethnic community of more than 340,000 in New Mexico, with others throughout the historical Spanish territorial claim of ''Nuevo México''. Alongside Californios and Tejanos, Neomexicanos are part of the larger Hispano community of the United States, who have lived in the American Southwest since the 16th century. These groups are differentiated by time period from the population of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lakota Language
Lakota ( ), also referred to as Lakhota, Teton or Teton Sioux, is a Siouan language spoken by the Lakota people of the Sioux tribes. Lakota is mutually intelligible with the two dialects of the Dakota language, especially Western Dakota, and is one of the three major varieties of the Sioux language. Speakers of the Lakota language make up one of the largest Native American language speech communities in the United States, with approximately 2,000 speakers, who live mostly in the northern plains states of North Dakota and South Dakota. Many communities have immersion programs for both children and adults. The language was first put into written form by European-American missionaries around 1840. The orthography has since evolved to reflect contemporary needs and usage. History and origin The Lakota people's creation stories say that language originated from the creation of the tribe. Other creation stories say language was invented by Iktomi. Phonology Vowels Lakota has fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gosiute Language
Gosiute is a dialect of the endangered Shoshoni language historically spoken by the Goshute people of the American Great Basin in modern Nevada and Utah. Modern Gosiute speaking communities include the Confederated Tribes of the Goshute Reservation and the Skull Valley Band of Goshute Indians. Status Historical 20th century Research by Wick R. Miller documenting the use of Gosiute in family settings on the Goshute Reservation in the 1960s reported the dialect to remain in use as primary means of communication and described comparatively low displacement by English, a fact attributed to the reservation's geographic isolation. Miller additionally reported that younger speakers tended to use Gosiute most, though noted that such a tendency could be a function of the development of English proficiency with age. Monolingual speakers of Gosiute were reported as recently as 1970. By 1994, language transmission to youth on the under 18 on the Goshute Reservation had become unco ...

Shoshone
The Shoshone or Shoshoni ( or ) are a Native American tribe with four large cultural/linguistic divisions: * Eastern Shoshone: Wyoming * Northern Shoshone: southern Idaho * Western Shoshone: Nevada, northern Utah * Goshute: western Utah, eastern Nevada They traditionally speak the Shoshoni language, part of the Numic languages branch of the large Uto-Aztecan language family. The Shoshone were sometimes called the Snake Indians by neighboring tribes and early American explorers. Their peoples have become members of federally recognized tribes throughout their traditional areas of settlement, often co-located with the Northern Paiute people of the Great Basin. Etymology The name "Shoshone" comes from ''Sosoni'', a Shoshone word for high-growing grasses. Some neighboring tribes call the Shoshone "Grass House People," based on their traditional homes made from ''sosoni''. Shoshones call themselves ''Newe'', meaning "People".Loether, Christopher"Shoshones."''Encyclopedia of the Gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skin Rash
A rash is a change of the human skin which affects its color, appearance, or texture. A rash may be localized in one part of the body, or affect all the skin. Rashes may cause the skin to change color, itch, become warm, bumpy, chapped, dry, cracked or blistered, swell, and may be painful. The causes, and therefore treatments for rashes, vary widely. Diagnosis must take into account such things as the appearance of the rash, other symptoms, what the patient may have been exposed to, occupation, and occurrence in family members. The diagnosis may confirm any number of conditions. The presence of a rash may aid diagnosis; associated signs and symptoms are diagnostic of certain diseases. For example, the rash in measles is an erythematous, morbilliform, maculopapular rash that begins a few days after the fever starts. It classically starts at the head, and spreads downwards. Differential diagnosis Common causes of rashes include: * Food allergy * Medication side effects * Anxiety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bronchitis
Bronchitis is inflammation of the bronchi (large and medium-sized airways) in the lungs that causes coughing. Bronchitis usually begins as an infection in the nose, ears, throat, or sinuses. The infection then makes its way down to the bronchi. Symptoms include coughing up sputum, wheezing, shortness of breath, and chest pain. Bronchitis can be acute or chronic. Acute bronchitis usually has a cough that lasts around three weeks, and is also known as a chest cold. In more than 90% of cases the cause is a viral infection. These viruses may be spread through the air when people cough or by direct contact. A small number of cases are caused by a bacterial infection such as ''Mycoplasma pneumoniae'' or ''Bordetella pertussis''. Risk factors include exposure to tobacco smoke, dust, and other air pollution. Treatment of acute bronchitis typically involves rest, paracetamol (acetaminophen), and nonsteroidal anti-inflammatory drugs (NSAIDs) to help with the fever. Chronic bronchi ...

Asthma
Asthma is a long-term inflammatory disease of the airways of the lungs. It is characterized by variable and recurring symptoms, reversible airflow obstruction, and easily triggered bronchospasms. Symptoms include episodes of wheezing, coughing, chest tightness, and shortness of breath. These may occur a few times a day or a few times per week. Depending on the person, asthma symptoms may become worse at night or with exercise. Asthma is thought to be caused by a combination of genetic and environmental factors. Environmental factors include exposure to air pollution and allergens. Other potential triggers include medications such as aspirin and beta blockers. Diagnosis is usually based on the pattern of symptoms, response to therapy over time, and spirometry lung function testing. Asthma is classified according to the frequency of symptoms, forced expiratory volume in one second (FEV1), and peak expiratory flow rate. It may also be classified as atopic or non-atopic, ...

Medicinal Herb
Medicinal plants, also called medicinal herbs, have been discovered and used in traditional medicine practices since prehistoric times. Plants synthesize hundreds of chemical compounds for various functions, including defense and protection against insects, fungi, diseases, and herbivorous mammals. The earliest historical records of herbs are found from the Sumerian civilization, where hundreds of medicinal plants including opium are listed on clay tablets, c. 3000 BC. The Ebers Papyrus from ancient Egypt, c. 1550 BC, describes over 850 plant medicines. The Greek physician Dioscorides, who worked in the Roman army, documented over 1000 recipes for medicines using over 600 medicinal plants in ''De materia medica'', c. 60 AD; this formed the basis of pharmacopoeias for some 1500 years. Drug research sometimes makes use of ethnobotany to search for pharmacologically active substances, and this approach has yielded hundreds of useful compounds. These include the common drugs asp ...
