The Food Protection Committee started in 1961 to provide objective quality standards for food-grade chemicals. Parts of the first edition were published in loose-leaf form between 1963 and 1966. The scope of the first edition is limited to substances amenable to chemical characterization or biological standardization which are added directly to ...
Carvedilol is a nonselective beta blocker and alpha-1 blocker. [5] How it improves outcomes is not entirely clear but may involve dilation of blood vessels. [5] Carvedilol was patented in 1978 and approved for medical use in the United States in 1995. [5] [8] It is on the World Health Organization's List of Essential Medicines. [9]
The International Numbering System for Food Additives (INS) is an international naming system for food additives, aimed at providing a short designation of what may be a lengthy actual name. [1] It is defined by Codex Alimentarius , the international food standards organisation of the World Health Organization (WHO) and Food and Agriculture ...
Sodium lactate is used to treat arrhythmias caused by overdosing of class I antiarrythmics, as well as pressor sympathomimetics which can cause hypertension. [10]It can be given intravenously as a source of bicarbonate for preventing or controlling mild to moderate metabolic acidosis in patients with restricted oral intake (for sodium bicarbonate) whose oxidative processes are not seriously ...
It can be prepared by treating a potassium-containing base such as potassium hydroxide or potassium carbonate with acetic acid: CH 3 COOH + KOH → CH 3 COOK + H 2 O. This sort of reaction is known as an acid-base neutralization reaction. At saturation, the sesquihydrate in water solution (CH 3 COOK·1½H 2 O) begins to form semihydrate at 41.3 ...
A functional specification is a kind of requirement specification, and may show functional block diagrams. [citation needed] A design or product specification describes the features of the solutions for the Requirement Specification, referring to either a designed solution or final produced solution. It is often used to guide fabrication ...
There are many different ways to prepare PBS solutions, common ones are Dulbecco's phosphate-buffered saline (DPBS) [2] and the Cold Spring Harbor protocol. [3] Some formulations of DPBS do not contain potassium and magnesium, while other ones contain calcium and/or magnesium (depending on whether or not the buffer is used on live or fixed tissue: the latter does not require CaCl 2 or MgCl 2).
Sodium hexametaphosphate (SHMP) is a salt of composition Na 6 [(PO 3) 6]. [3] Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO 3), of which the hexamer is one, and is usually the compound referred to by this name.
