Diminazene
Diminazene (INN; also known as diminazen) is an anti-infective medication for animals that is sold under a variety of brand names. It is effective against certain protozoa such as ''Babesia'', ''Trypanosoma'', and '' Cytauxzoon''. The drug may also be effective against certain bacteria including ''Brucella'' and ''Streptococcus''. Chemically it is a di-amidine and it is formulated as its aceturate salt, diminazene aceturate. The mechanism is not well understood; it probably inhibits DNA replication, but also has affinity to RNA. __TOC__ Side effects Acute side effects include vomiting, diarrhea, and hypotension (low blood pressure). Diminazen can harm the liver, kidneys and brain, which is potentially life-threatening; camels are especially susceptible to these effects. Resistance The Gibe River Valley in southwest Ethiopia showed universal resistance between July 1989 and February 1993. This likely indicates a permanent loss of function in this area against the tested target ...

Trypanosoma Congolense
''Trypanosoma congolense'' is a species of trypanosomes and is the major pathogen responsible for the disease nagana in cattle and other animals including sheep, pigs, goats, horses and camels, dogs, as well as laboratory mice. It is the most common cause of nagana in east Africa, but is also a major cause of nagana in west Africa. This parasite is spread by tsetse flies. In its mammalian host, ''Trypanosoma congolense'' only lives in blood vessels, and causes in particular anaemia. African Animal Trypanosomiasis

Intramuscular Injection
Intramuscular injection, often abbreviated IM, is the injection of a substance into a muscle. In medicine, it is one of several methods for parenteral administration of medications. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than subcutaneous or intradermal injections. Medication administered via intramuscular injection is not subject to the first-pass metabolism effect which affects oral medications. Common sites for intramuscular injections include the deltoid muscle of the upper arm and the gluteal muscle of the buttock. In infants, the vastus lateralis muscle of the thigh is commonly used. The injection site must be cleaned before administering the injection, and the injection is then administered in a fast, darting motion to decrease the discomfort to the individual. The volume to be injected in the muscle is usually limited to 2–5 milliliters, depending on in ...

Pharmaceutical Formulation
Pharmaceutical formulation, in pharmaceutics, is the process in which different chemical substances, including the active drug, are combined to produce a final medicinal product. The word ''formulation'' is often used in a way that includes dosage form. Stages and timeline Formulation studies involve developing a preparation of the drug which is both stable and acceptable to the patient. For orally administered drugs, this usually involves incorporating the drug into a tablet or a capsule. It is important to make the distinction that a tablet contains a variety of other potentially inert substances apart from the drug itself, and studies have to be carried out to ensure that the encapsulated drug is compatible with these other substances in a way that does not cause harm, whether direct or indirect. Preformulation involves the characterization of a drug's physical, chemical, and mechanical properties in order to choose what other ingredients (excipients) should be used in the pre ...

Amidines
Amidines are organic compounds with the functional group RC(NR)NR2, where the R groups can be the same or different. They are the imine derivatives of amides (RC(O)NR2). The simplest amidine is formamidine, HC(=NH)NH2. Examples of amidines include: * DBU * diminazene * benzamidine * Pentamidine * Paranyline Preparation A common route to primary amidines is the Pinner reaction. Reaction of the nitrile with alcohol in the presence of acid gives an iminoether. Treatment of the resulting compound with ammonia then completes the conversion to the amidine. Instead of using a Bronsted acid, Lewis acids such as aluminium trichloride promote the direct amination of nitriles. They are also generated by amination of an imidoyl chloride. They are also prepared by the addition of organolithium reagents to diimines, followed by protonation or alkylation. Dimethylformamide acetal reacts with primary amines to give amidines: :Me2NC(H)(OMe)2 + RNH2 → Me2NC=NHR + 2 MeOH Properties and applica ...

Boran
Boran (also spelled Buran, Middle Persian: ; New Persian: پوران‌دخت, ''Pūrāndokht'') was Sasanian queen (or '' banbishn'') of Iran from 630 to 632, with an interruption of some months. She was the daughter of king (or ''shah'') Khosrow II () and the Byzantine princess Maria. She is the second of only three women to rule in Iranian history, the others being Musa of Parthia, and Boran's sister Azarmidokht. In 628, her father was overthrown and executed by her brother-husband Kavad II, who also had all Boran's brothers and half-brothers executed, initiating a period of fractionalism within the empire. Kavad II died some months later, and was succeeded by his eight-year-old son Ardashir III, who after a rule of nigh two years, was killed and usurped by the Iranian military officer Shahrbaraz. Boran shortly ascended the throne with the aid of the military commander Farrukh Hormizd, who helped her to overthrow Shahrbaraz. She and her sister were the only legitimate heirs ...

Gibe River
The Gibe River (also Great Gibe River) is by far the largest tributary of the Omo River in Ethiopia and typically flowing south-southeast. The confluence of the large Gibe River at with the smaller Wabe River forms the even larger Omo River. Consequently, the whole drainage basin is sometimes called the ''Omo-Gibe River Basin'' with the Gibe and the Omo draining the upper and lower reaches, respectively. Located in southwest Ethiopia, the Gibe River is not navigable, like almost all rivers in the country. Overview The Gibe rises at an elevation of more than 2,000 m north of Bila town and west of the Chomen swamp (specifically, from Gudeya Bila woreda, which is located in the East Welega Zone, Oromia Region). The river is then flowing generally to the southeast to its confluence with the Wabe River. Its tributaries include the Amara, Alanga and Gilgel Gibe rivers. The southern drainage area of the Gibe includes the historic Gibe region, where a number of the former kingdoms o ...

Hypotension
Hypotension is low blood pressure. Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood. Blood pressure is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the maximum and minimum blood pressures, respectively. A systolic blood pressure of less than 90 millimeters of mercury (mmHg) or diastolic of less than 60 mmHg is generally considered to be hypotension. Different numbers apply to children. However, in practice, blood pressure is considered too low only if noticeable symptoms are present. Symptoms include dizziness or lightheadedness, confusion, feeling tired, weakness, headache, blurred vision, nausea, neck or back pain, an irregular heartbeat or feeling that the heart is skipping beats or fluttering, or fainting. Hypotension is the opposite of hypertension, which is high blood pressure. It is best understood as a physiological st ...

DNA Replication
In molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance. This is essential for cell division during growth and repair of damaged tissues, while it also ensures that each of the new cells receives its own copy of the DNA. The cell possesses the distinctive property of division, which makes replication of DNA essential. DNA is made up of a double helix of two complementary strands. The double helix describes the appearance of a double-stranded DNA which is thus composed of two linear strands that run opposite to each other and twist together to form. During replication, these strands are separated. Each strand of the original DNA molecule then serves as a template for the production of its counterpart, a process referred to as semiconservative replication. As a result of semi-conservative rep ...

Salt (chemistry)
In chemistry, a salt is a chemical compound consisting of an ionic assembly of positively charged cations and negatively charged anions, which results in a compound with no net electric charge. A common example is table salt, with positively charged sodium ions and negatively charged chloride ions. The component ions in a salt compound can be either inorganic, such as chloride (Cl−), or organic, such as acetate (). Each ion can be either monatomic, such as fluoride (F−), or polyatomic, such as sulfate (). Types of salt Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called ''alkali salts'' and salts that produce hydrogen ions when dissolved in water are called ''acid salts''. ''Neutral salts'' are those salts that are neither acidic nor basic. Zwitterions contain an anionic and a cationic centre in the same molecule, but are not considered salts. Examples of zwitterions are amino acids, many metabolites, peptid ...
