CPTH
Starlicide or gull toxicant is a chemical avicide that is highly toxic to European starlings (thus the name) and gulls, but less toxic to other birds or to mammals such as humans and pets. Synonyms The name Starlicide originated as a registered trademark of the animal feed manufacturer Ralston-Purina in St. Louis, Missouri. Starlicide is a small molecule in which a central benzene ring is modified by amine, chloro and methyl substituents in a specific pattern. Because special names exist for benzene rings modified with one or two of these functional groups, several synonymous chemical names may be encountered: 3-chloro-4-methylaniline or 3-chloro-4-methylbenzenamine, 2-chloro-4-aminotoluene, or 3-chloro-''p''-toluidine. Numbered groups (2-chloro, 4-amino) also may be named out of order; the numbers of such groups equal the number of carbon atoms in the benzene ring separating them from the group implied in the special name. Preparations of this chemical may be named as a hydr ...

Avicide
An avicide is any substance (normally a chemical) used to kill birds. Commonly used avicides include strychnine (also used as rodenticide and predacide), DRC-1339 (3-chloro-4-methylaniline hydrochloride, Starlicide) and CPTH (3-chloro-p-toluidine, the free base of Starlicide), Avitrol (4-aminopyridine) and chloralose (also used as rodenticide). In the past, highly concentrated formulations of parathion in diesel oil were sprayed by aircraft over birds' nesting colonies. Avicides are banned in many countries because of their ecological impact, which is poorly studied. They are still used in the United States, Canada, Australia and New Zealand. The practice is criticized by animal rights advocates and those who kill birds with guns and traps. Pigeon fanciers sometimes poison problematic birds of prey, even in countries like Russia and Ukraine where avicides are illegal.Wegler, R.: Chemie der Pflanzenschutz- und Schädlingsbekämpfungsmittel, Band 1, Springer, 1970 (german) Se ...

Freebase (chemistry)
Free base (freebase, free-base) is the conjugate base (deprotonated) form of an amine, as opposed to its conjugate acid (protonated) form. The amine is often an alkaloid, such as nicotine, cocaine, morphine, and ephedrine, or derivatives thereof. Freebasing is a more efficient method of self-administering alkaloids via the smoking route. Properties Some alkaloids are more stable as ionic salts than as free base. The salts usually exhibit greater water solubility. Common counterions include chloride, bromide, sulfate, phosphate, nitrate, acetate, oxalate, citrate, and tartrate. Ammonium salts formed from the acid-base reaction with hydrochloric acid are known as hydrochlorides. For example, compare the free base hydroxylamine (NH2OH) with the salt hydroxylamine hydrochloride (NH3OH+ Cl−). Freebasing Cocaine hydrochloride ("powder cocaine") cannot be smoked as it decomposes at the high temperatures produced by smoking. Free base cocaine, on the other hand, has a melting p ...

Parts Per Million
In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million (ppm, ), parts-per-billion (ppb, ), parts-per-trillion (ppt, ) and parts-per-quadrillion (ppq, ). This notation is not part of the International System of Units (SI) system and its meaning is ambiguous. Overview Parts-per notation is often used describing dilute solutions in chemistry, for instance, the relative abundance of dissolved minerals or pollutants in water. The quantity "1 ppm" can be used for a mass fraction if a water-borne pollutant is present at one-millionth of a gram per gram of sample solution. When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equat ...

Brown Rice
Brown rice is a whole grain rice with the inedible outer Rice hulls, hull removed. This kind of rice sheds its outer hull or husk but the bran and germ layer remain on, constituting the brown or tan colour of rice. White rice is the same grain without the hull, the Rice bran, bran layer, and the cereal germ. Red rice, Oryza glaberrima#American cultivars, gold rice, and black rice (also called purple rice) are all whole rices with differently pigmented outer layers. Cooking time Brown rice generally needs longer cooking times than white rice, unless it is broken rice, broken or flour blasted (which perforates the bran without removing it). Studies by Gujral and Kumar in 2003 estimated a cooking time between 35 and 51 minutes. A shorter cooking time is necessary for "converted" or parboiled rice. Storage Brown rice has a shelf life of approximately 6 months, but hermetic storage, refrigeration or freezing can significantly extend its lifetime. Freezing, even periodically, can al ...

Rice
Rice is the seed of the grass species ''Oryza sativa'' (Asian rice) or less commonly ''Oryza glaberrima ''Oryza glaberrima'', commonly known as African rice, is one of the two domesticated rice species. It was first domesticated and grown in West Africa around 3,000 years ago. In agriculture, it has largely been replaced by higher-yielding Asian r ...'' (African rice). The name wild rice is usually used for species of the genera ''Zizania (genus), Zizania'' and ''Porteresia'', both wild and domesticated, although the term may also be used for primitive or uncultivated varieties of ''Oryza''. As a cereal, cereal grain, domesticated rice is the most widely consumed staple food for over half of the world's World population, human population,Abstract, "Rice feeds more than half the world's population." especially in Asia and Africa. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize. Since sizable portions of sugarcane and ma ...

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 ...

Visceral Gout
Visceral gout is a disease of birds in which kidney failure causes a build-up of urates in the internal organs, leaving a chalky white coating on them. Symptoms include anorexia and emaciation. It is a problem common to caged birds. Vultures are particularly sensitive to poisoning by diclofenac, which leads to kidney failure, visceral gout, and death. Threat to vultures The collapse of the vulture population in India and Pakistan, to about a twentieth of their original numbers, has been caused by diclofenac, which is a non-steroidal anti-inflammatory drug (NSAID). Diclofenac is given to working and ill farm cattle to reduce pain so that they can work on the land for longer. Farmers leave dead farm animals out in the open for the vultures to tidy up, and the vultures then feed from the carcasses of the cattle that die, and are poisoned by the diclofenac contained in the flesh they eat. Vultures are now not present in large enough numbers to tidy up all the dead animals. Instead, ...

Uremic Poisoning
Acute kidney injury (AKI), previously called acute renal failure (ARF), is a sudden decrease in kidney function that develops within 7 days, as shown by an increase in serum creatinine or a decrease in urine output, or both. Causes of AKI are classified as either prerenal (due to decreased blood flow to the kidney), intrinsic renal (due to damage to the kidney itself), or postrenal (due to blockage of urine flow). Prerenal causes of AKI include sepsis, dehydration, excessive blood loss, cardiogenic shock, heart failure, cirrhosis, and certain medications like ACE inhibitors or NSAIDs. Intrinsic renal causes of AKI include glomerulonephritis, lupus nephritis, acute tubular necrosis, certain antibiotics, and chemotherapeutic agents. Postrenal causes of AKI include kidney stones, bladder cancer, neurogenic bladder, enlargement of the prostate, narrowing of the urethra, and certain medications like anticholinergics. The diagnosis of AKI is made based on a person's signs and symptom ...

Corvus Frugilegus
The rook (''Corvus frugilegus'') is a member of the family Corvidae in the passerine order of birds. It is found in the Palearctic, its range extending from Scandinavia and western Europe to eastern Siberia. It is a large, gregarious, black-feathered bird, distinguished from similar species by the whitish featherless area on the face. Rooks nest collectively in the tops of tall trees, often close to farms or villages, the groups of nests being known as rookeries. Rooks are mainly resident birds, but the northernmost populations may move southwards to avoid the harshest winter conditions. The birds form flocks in winter, often in the company of other ''Corvus'' species or jackdaws. They return to their rookeries and breeding takes place in spring. They forage on arable land and pasture, probing the ground with their strong bills and feeding largely on grubs and soil-based invertebrates, but also consuming cereals and other plant material. Historically, farmers have accused the b ...

Phasianus Colchicus
The common pheasant (''Phasianus colchicus'') is a bird in the pheasant family (Phasianidae). The genus name comes from Latin ''phasianus'', "pheasant". The species name ''colchicus'' is Latin for "of Colchis" (modern day Georgia), a country on the Black Sea where pheasants became known to Europeans. Although ''Phasianus'' was previously thought to be closely related to the genus ''Gallus'', the genus of junglefowl and domesticated chickens, recent studies show that they are in different subfamilies, having diverged over 20 million years ago. It is native to Asia and parts of Europe like the northern foothills of the Caucasus and the Balkans. It has been widely introduced elsewhere as a game bird. In parts of its range, namely in places where none of its relatives occur such as in Europe, where it is naturalised, it is simply known as the "pheasant". Ring-necked pheasant is both the name used for the species as a whole in North America and also the collective name for a number o ...
