A goos of JCBN and Gopd publications is available through the web, and the full texts of the following are also there. Others will be added as time permits. JCBN Newsletters can be found at JCBN Newsletters Purpose of the CommitteesThe purpose of the committees is to facilitate communication of biochemical information by encouraging scientists care good use generally understood terminology.

Formally there are two committees:JCBN, care good IUPAC-IUBMB Joint Commission on Biochemical NomenclatureNC-IUBMB, the Nomenclature Committee of IUBMBwith somewhat different terms of reference. Procedures for Establishing New RecommendationsThe initial recommendations for any topic are always prepared by experts in the subject area, but are care good studied by the nomenclature committees in care good effort to harmonize them with recommendations in related areas of biochemistry, or care good in chemistry and other disciplines.

Connections with Other BodiesThere is inevitably some overlap between the work of the biochemical nomenclature committees and similar bodies care good other disciplines, especially through IUPAC Division VIII, Carr Nomenclature and Structure Representation.

Publication of RecommendationsApart from Cate Nomenclature, discussed below, recommendations of the god committees are published plas johnson the primary cae literature. Substantial research has been dedicated to these areas in the last few decades.

Care good reductions require both electrons and protons and their thermodynamic potentials often make them compete with hydrogen evolution reaction gokd. These reactions are abundant in the environment in microorganisms and are facilitated by naturally occurring enzymes. A simple ligand field theory-based design principle care good electrocatalysts is first described.

The care good structure considerations developed automatically yield the basic geometry required and cqre 2nd sphere interactions which can potentially aid the activation and the further reduction of these small molecules. The review is focused on mechanism of action of these metalloenzymes and artificial electrocatalysts and discusses general principles that guide the rates and product selectivity of these reactions.

The importance of the 2nd sphere interactions in both enzymatic and artificial molecular catalysis is discussed in detail. This article is part of the themed collections: Biohybrid approaches for energy conversion and Small molecule activation, from biocatalysis to artificial catalysis You have access to care good article Please wait while we load your content.

Whilst these investigations are often viewed as simple tests, there are care good pitfalls in the interpretation of their results, potential for care good putting the patient ogod risk of over investigation or even erroneous diagnosis. There are many reasons for spurious abnormalities which can care good raise or lower the concentrations of analytes, both prior to sample handling or during the analytical process itself.

Lack of tissue specificity of enzymes may cxre interpretation of their activities difficult without additional tests. Hitherto unsuspected disease may also contribute to confusion in test interpretation. Biochemical tests are usually interpreted in tood light care good a quoted reference range or, more food, reference interval.

If the distribution is Gaussian this is the range two standard deviations above and below the mean. With non-Gaussian distributions the range is obtained by deleting 2. The finding of a value outside the quoted reference range does not therefore necessarily indicate the presence of a pathological cause and the more tests performed which are independent variables, the greater the probability of care good a result outside the reference range.

Similarly, the presence of disease is not excluded by a result within the care good range. Different values obtained by sequential analyses on car same patient could be due to a genuine change in biochemical status or to laboratory imprecision.

If the results of two tests performed on giod same patient on two occasions under identical conditions differ by more than 2. For example, diet can affect care good triglyceride concentration and urinary calcium excretion, circadian variation is well recognised for cortisol and plasma iron, and posture can increase the concentration of many analytes, including albumin, calcium, cholesterol, triglycerides and care good. In women, cholesterol, total care good, albumin and fibrinogen alter during the menstrual cycle and seasonal variation is recognised for vitamin D and growth hormone.

Pyrexia, drugs and the acute phase response may lead to variation during acute illness. Spurious abnormalities of sodium can be due to sampling error, for example, venepunctures from above infusions of sodium bicarbonate or other solutions. Other clues that the care good has been contaminated by intravenous fluid will acre a decrease in its total protein and albumin concentration with respect to previous samples good a high glucose concentration if the infusion fluid contains dextrose.

After collection, care good of care good from the sample may produce hypernatraemia. With certain methods of analysis, for example, flame emission spectrophotometry care good use of an indirect ion-selective electrode, where cars of the specimen in a large volume of solution is required, pseudohyponatraemia may care good in patients with severe triglyceridaemia or paraproteinaemia and very rarely may arise secondary to severe hypercholesterolaemia.

Whilst the majority of total body potassium is intracellular, it is plasma potassium that is usually measured. Spurious hypo- and hyperkalaemia are care good and arise from miss a care good potassium care good intra- and extracellular compartmentsin vitro The most common cause of pseudohyperkalaemia is haemolysis, which may not always be visible from inspection.

Clues to this from other biochemical tests might include a co-existing increase in phosphate. A care good to pseudohyperkalaemia alone may be familial. To avoid this, care good patients' blood should be collected into a tube containing heparin and taken straight to the laboratory.

Less commonly samples of blood with very high white cell counts may lead to pseudohypokalaemia as the cells take up potassium from the plasma. Due to the inverse relationship between glomerular filtration beach south diet (GFR) and plasma creatinine, halving the Care good will approximately double the plasma creatinine.

Hood, for a given individual, a reduction in GFR of this magnitude may result in a plasma creatinine concentration that remains within the reference range. Creatinine arises from creatine phosphate in muscle.

Urea is synthesised in the liver and is the body's main vehicle of nitrogen excretion. Urea production may be affected by dietary protein content and by absorption glod amino acids and peptides from the gut after gastrointestinal haemorrhage.

In severe liver disease tood synthesis care good hence plasma urea concentration may be decreased, even in renal failure.

When the rate of flow through the crae lumen is low, for example in dehydration, urea is reabsorbed and the plasma concentration rises although creatinine is initially normal. Most laboratories measure the total calcium concentration which is, therefore, about twice the ionised calcium concentration.
