Ticarcillin Clavulanate
Ticarcillin is a carboxypenicillin. It can be sold and used in combination with clavulanate as ticarcillin/clavulanic acid. Because it is a penicillin, it also falls within the larger class of beta-lactam antibiotics. Its main clinical use is as an injectable antibiotic for the treatment of Gram-negative bacteria, particularly ''Pseudomonas aeruginosa'' and Proteus vulgaris. It is also one of the few antibiotics capable of treating ''Stenotrophomonas maltophilia'' infections. It is provided as a white or pale-yellow powder. It is highly soluble in water, but should be dissolved only immediately before use to prevent degradation. It was patented in 1963. Mechanism of action Ticarcillin's antibiotic properties arise from its ability to prevent cross-linking of peptidoglycan during cell wall synthesis, when the bacteria try to divide, causing cell death. Ticarcillin, like penicillin, contains a β-lactam ring that can be cleaved by beta-lactamases, resulting in inactivation ...

Intravenous Therapy
Intravenous therapy (abbreviated as IV therapy) is a medical technique that administers fluids, medications and nutrients directly into a person's vein. The intravenous route of administration is commonly used for rehydration or to provide nutrients for those who cannot, or will not—due to reduced mental states or otherwise—consume food or water by mouth. It may also be used to administer medications or other medical therapy such as blood products or electrolytes to correct electrolyte imbalances. Attempts at providing intravenous therapy have been recorded as early as the 1400s, but the practice did not become widespread until the 1900s after the development of techniques for safe, effective use. The intravenous route is the fastest way to deliver medications and fluid replacement throughout the body as they are introduced directly into the circulatory system and thus quickly distributed. For this reason, the intravenous route of administration is also used for the consump ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Methiopropamine
Methiopropamine (MPA) is a thiophene ring-based structural analog of methamphetamine originally reported in 1942. Chemically it is not a phenethylamine or amphetamine and is not their functional analog either. It originally appeared for public sale in the UK in December 2010 as a "research chemical" or "legal high", recently branded as Blow. It has limited popularity as a recreational stimulant. Pharmacology Methiopropamine functions as a selective norepinephrine-dopamine reuptake inhibitor that is approximately 1.85 times more selective for norepinephrine than dopamine. It is approximately one third as potent as dextroamphetamine as a norepinephrine reuptake inhibitor and one fifth as much as a dopamine reuptake inhibitor. It displays negligible activity as a serotonin reuptake inhibitor. Methiopropamine has the potential for significant acute toxicity with cardiovascular, gastrointestinal, and psychotic symptoms.

Beta-lactamases
Beta-lactamases, (β-lactamases) are enzymes () produced by bacteria that provide multi-resistance to beta-lactam antibiotics such as penicillins, cephalosporins, cephamycins, monobactams and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase. Beta-lactamase provides antibiotic resistance by breaking the antibiotics' structure. These antibiotics all have a common element in their molecular structure: a four-atom ring known as a beta-lactam (β-lactam) ring. Through hydrolysis, the enzyme lactamase breaks the β-lactam ring open, deactivating the molecule's antibacterial properties. Beta-lactam antibiotics are typically used to target a broad spectrum of gram-positive and gram-negative bacteria. Beta-lactamases produced by gram-negative bacteria are usually secreted, especially when antibiotics are present in the environment. Structure The structure of a ''Streptomyces'' serine β-lactamase (SBLs) is given by . The alpha-beta fold ( ...

Pseudomonas
''Pseudomonas'' is a genus of Gram-negative, Gammaproteobacteria, belonging to the family Pseudomonadaceae and containing 191 described species. The members of the genus demonstrate a great deal of metabolic diversity and consequently are able to colonize a wide range of niches. Their ease of culture ''in vitro'' and availability of an increasing number of ''Pseudomonas'' strain genome sequences has made the genus an excellent focus for scientific research; the best studied species include ''P. aeruginosa'' in its role as an opportunistic human pathogen, the plant pathogen '' P. syringae'', the soil bacterium '' P. putida'', and the plant growth-promoting ''P. fluorescens, P. lini, P. migulae'', and ''P. graminis''. Because of their widespread occurrence in water and plant seeds such as dicots, the pseudomonads were observed early in the history of microbiology. The generic name ''Pseudomonas'' created for these organisms was defined in rather vague terms by Walter Migula i ...

Urinary Tract Infections
A urinary tract infection (UTI) is an infection that affects part of the urinary tract. When it affects the lower urinary tract it is known as a bladder infection (cystitis) and when it affects the upper urinary tract it is known as a kidney infection (pyelonephritis). Symptoms from a lower urinary tract infection include pain with urination, frequent urination, and feeling the need to urinate despite having an empty bladder. Symptoms of a kidney infection include fever and flank pain usually in addition to the symptoms of a lower UTI. Rarely the urine may appear bloody. In the very old and the very young, symptoms may be vague or non-specific. The most common cause of infection is ''Escherichia coli'', though other bacteria or fungi may sometimes be the cause. Risk factors include female anatomy, sexual intercourse, diabetes, obesity, and family history. Although sexual intercourse is a risk factor, UTIs are not classified as sexually transmitted infections (STIs). Kidney ...

Carbenicillin
Carbenicillin is a bactericidal antibiotic belonging to the carboxypenicillin subgroup of the penicillins. It was discovered by scientists at Beecham and marketed as Pyopen. It has Gram-negative coverage which includes ''Pseudomonas aeruginosa'' but limited Gram-positive coverage. The carboxypenicillins are susceptible to degradation by beta-lactamase enzymes, although they are more resistant than ampicillin to degradation. Carbenicillin is also more stable at lower pH than ampicillin. Pharmacology The antibiotic is highly soluble in water and is acid-labile. A typical lab working concentration is 50 to 100 µg per ml. It is a semi-synthetic analogue of the naturally occurring benzyl-penicillin. Carbenicillin at high doses can cause bleeding. Use of carbenicillin can cause hypokalemia by promoting potassium loss at the distal convoluted tubule of the kidney. In molecular biology, carbenicillin may be preferred as a selecting agent (see Plasmid stabilisation technology) be ...

Beecham (pharmaceutical Company)
The Beecham Group plc was a British pharmaceutical company. It was once a constituent of the FTSE 100 Index. Beecham, after having merged with American pharmaceutical company SmithKline Beckman to become SmithKline Beecham, merged with Glaxo Wellcome to become GlaxoSmithKline (GSK). GSK still uses the Beechams brand name in the UK for its over-the-counter cold and flu relief products. Early history Beecham began as the family business of Thomas Beecham (1820–1907), a chemist. (Beecham would become the grandfather of music conductor Thomas Beecham, 1879–1961). As a boy, Beecham worked as a shepherd, selling herbal remedies as a sideline. He later became a travelling salesman or peddler full time. His first product was Beecham's Pills, a laxative, in 1842. Subsequent success enabled him to open a shop in Wigan in 1847. Beecham opened its first factory in 1849 in St Helens, Lancashire, for the rapid production of medicines. Under his son, Sir Joseph Beecham, 1st Baronet (184 ...

Agrobacterium
''Agrobacterium'' is a genus of Gram-negative bacteria established by H. J. Conn that uses horizontal gene transfer to cause tumors in plants. ''Agrobacterium tumefaciens'' is the most commonly studied species in this genus. ''Agrobacterium'' is well known for its ability to transfer DNA between itself and plants, and for this reason it has become an important tool for genetic engineering. Nomenclatural History Leading up to the 1990s, the genus ''Agrobacterium'' was used as a wastebasket taxon. With the advent of 16S sequencing, many ''Agrobacterium'' species (especially the marine species) were reassigned to genera such as ''Ahrensia'', ''Pseudorhodobacter'', ''Ruegeria'', and ''Stappia''. The remaining ''Agrobacterium'' species were assigned to three biovars: biovar 1 (''Agrobacterium tumefaciens''), biovar 2 (''Agrobacterium rhizogenes''), and biovar 3 (''Agrobacterium vitis''). In the early 2000s, ''Agrobacterium'' was synonymized with the genus ''Rhizobium''. This move pr ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
