Ionic currents underlying spontaneous action potentials in isolated cerebellar Purkinje neurons. (1/2206)

Acutely dissociated cell bodies of mouse Purkinje neurons spontaneously fired action potentials at approximately 50 Hz (25 degrees C). To directly measure the ionic currents underlying spontaneous activity, we voltage-clamped the cells using prerecorded spontaneous action potentials (spike trains) as voltage commands and used ionic substitution and selective blockers to isolate individual currents. The largest current flowing during the interspike interval was tetrodotoxin-sensitive sodium current (approximately -50 pA between -65 and -60 mV). Although the neurons had large voltage-dependent calcium currents, the net current blocked by cobalt substitution for calcium was outward at all times during spike trains. Thus, the electrical effect of calcium current is apparently dominated by rapidly activated calcium-dependent potassium currents. Under current clamp, all cells continued firing spontaneously (though approximately 30% more slowly) after block of T-type calcium current by mibefradil, and most cells continued to fire after block of all calcium current by cobalt substitution. Although the neurons possessed hyperpolarization-activated cation current (Ih), little current flowed during spike trains, and block by 1 mM cesium had no effect on firing frequency. The outward potassium currents underlying the repolarization of the spikes were completely blocked by 1 mM TEA. These currents deactivated quickly (<1 msec) after each spike. We conclude that the spontaneous firing of Purkinje neuron cell bodies depends mainly on tetrodotoxin-sensitive sodium current flowing between spikes. The high firing rate is promoted by large potassium currents that repolarize the cell rapidly and deactivate quickly, thus preventing strong hyperpolarization and restoring a high input resistance for subsequent depolarization.  (+info)

Cyanide poisoning: pathophysiology and treatment recommendations. (2/2206)

This paper aims to assess and compare currently available antidotes for cyanide poisoning. Such evaluation, however, is difficult. Thus, extrapolation from the results of animal studies has potential pitfalls, as significant inter-species differences in response may exist, and these experiments often involve administration of toxin and antidote almost simultaneously, rather than incorporating a more realistic time delay before initiation of treatment. Direct inference from human case reports is also problematic; either because of uncertainties over the exposure levels involved (and hence the likely outcome without treatment), or because of difficulties in identifying the specific contribution of a particular antidote within the overall treatment regimen. Certainly an effort to compare the relative efficacy of cyanide antidotes produces equivocal findings, with no single regimen clearly standing out. Indeed, factors such as the risks of antidote toxicity to various individuals and other practical issues, may be more important considerations. There is therefore no single treatment regimen which is best for all situations. Besides individual risk factors for antidote toxicity, the nature of the exposure and hence its likely severity, the evolving clinical features and the number of persons involved and their proximity to hospital facilities, all need to be considered. Clinically mild poisoning may be treated by rest, oxygen and amyl nitrite. Intravenous antidotes are indicated for moderate poisoning. Where the diagnosis is uncertain, sodium thiosulphate may be the first choice. With severe poisoning, an additional agent is required. Given the various risks with methaemoglobin formers or with unselective use of kelocyanor, hydroxocobalamin may be preferred from a purely risk-benefit perspective. However the former alternatives will likely remain important.  (+info)

Source of inappropriate receptive fields in cortical somatotopic maps from rats that sustained neonatal forelimb removal. (3/2206)

Previously this laboratory demonstrated that forelimb removal at birth in rats results in the invasion of the cuneate nucleus by sciatic nerve axons and the development of cuneothalamic cells with receptive fields that include both the forelimb-stump and the hindlimb. However, unit-cluster recordings from primary somatosensory cortex (SI) of these animals revealed few sites in the forelimb-stump representation where responses to hindlimb stimulation also could be recorded. Recently we reported that hindlimb inputs to the SI forelimb-stump representation are suppressed functionally in neonatally amputated rats and that GABAergic inhibition is involved in this process. The present study was undertaken to assess the role that intracortical projections from the SI hindlimb representation may play in the functional reorganization of the SI forelimb-stump field in these animals. The SI forelimb-stump representation was mapped during gamma-aminobutyric acid (GABA)-receptor blockade, both before and after electrolytic destruction of the SI hindlimb representation. Analysis of eight amputated rats showed that 75.8% of 264 stump recording sites possessed hindlimb receptive fields before destruction of the SI hindlimb. After the lesions, significantly fewer sites (13.2% of 197) were responsive to hindlimb stimulation (P < 0.0001). Electrolytic destruction of the SI lower-jaw representation in four additional control rats with neonatal forelimb amputation did not significantly reduce the percentage of hindlimb-responsive sites in the SI stump field during GABA-receptor blockade (P = 0.98). Similar results were obtained from three manipulated rats in which the SI hindlimb representation was silenced temporarily with a local cobalt chloride injection. Analysis of response latencies to sciatic nerve stimulation in the hindlimb and forelimb-stump representations suggested that the intracortical pathway(s) mediating the hindlimb responses in the forelimb-stump field may be polysynaptic. The mean latency to sciatic nerve stimulation at responsive sites in the GABA-receptor blocked SI stump representation of neonatally amputated rats was significantly longer than that for recording sites in the hindlimb representation [26.3 +/- 8.1 (SD) ms vs. 10.8 +/- 2.4 ms, respectively, P < 0.0001]. These results suggest that hindlimb input to the SI forelimb-stump representation detected in GABA-blocked cortices of neonatally forelimb amputated rats originates primarily from the SI hindlimb representation.  (+info)

Regulation of interleukin-8 expression by reduced oxygen pressure in human glioblastoma. (4/2206)

Oxygen deprivation is an important biological feature of tumor growth. We previously showed that in glioma, anoxia increases expression of IL-8, a chemokine and angiogenic factor. Here, we analysed for the first time the biochemical mechanisms inducing the IL-8 gene upon anoxia in glioma cells, and showed that they differ from those inducing the VEGF gene. Both genes are induced in biologically and genetically heterogenous glioblastoma cell lines (LN-229, LN-Z308, U87MG, T98G), whereas, in gliosarcoma cells (D247MG), only the VEGF gene is induced. The kinetics of IL-8 and VEGF mRNA inductions differ in these cells and reoxygenation experiments showed that the induction is due to the anoxic stress per se. Furthermore, in LN-229 and LN-Z308 cell lines actinomycin D, DRB and nuclear run-on experiments showed that anoxia stimulates increased transcription of both genes. Electromobility shift assays show increased protein binding to the AP-1 site on the IL-8 promoter following anoxia treatment. Finally, in situ hybridization on glioblastoma sections shows that the in vivo expression patterns of IL-8 and VEGF genes overlap, but are not identical. Since intratumoral augmentation of IL-8 and VEGF secretion, following microenvironmental decreases in oxygen pressure, may promote angiogenesis, further definition of these pathways is essential to appropriately target them for antitumoral therapy.  (+info)

Acetylcholine-induced membrane potential changes in endothelial cells of rabbit aortic valve. (5/2206)

1. Using a microelectrode technique, acetylcholine (ACh)-induced membrane potential changes were characterized using various types of inhibitors of K+ and Cl- channels in rabbit aortic valve endothelial cells (RAVEC). 2. ACh produced transient then sustained membrane hyperpolarizations. Withdrawal of ACh evoked a transient depolarization. 3. High K+ blocked and low K+ potentiated the two ACh-induced hyperpolarizations. Charybdotoxin (ChTX) attenuated the ACh-induced transient and sustained hyperpolarizations; apamin inhibited only the sustained hyperpolarization. In the combined presence of ChTX and apamin, ACh produced a depolarization. 4. In Ca2+-free solution or in the presence of Co2+ or Ni2+, ACh produced a transient hyperpolarization followed by a depolarization. In BAPTA-AM-treated cells, ACh produced only a depolarization. 5. A low concentration of A23187 attenuated the ACh-induced transient, but not the sustained, hyperpolarization. In the presence of cyclopiazonic acid, the hyperpolarization induced by ACh was maintained after ACh removal; this maintained hyperpolarization was blocked by Co2+. 6. Both NPPB and hypertonic solution inhibited the membrane depolarization seen after ACh washout. Bumetanide also attenuated this depolarization. 7. It is concluded that in RAVEC, ACh produces a two-component hyperpolarization followed by a depolarization. It is suggested that ACh-induced Ca2+ release from the storage sites causes a transient hyperpolarization due to activation of ChTX-sensitive K+ channels and that ACh-activated Ca2+ influx causes a sustained hyperpolarization by activating both ChTX- and apamin-sensitive K+ channels. Both volume-sensitive Cl- channels and the Na+-K+-Cl- cotransporter probably contribute to the ACh-induced depolarization.  (+info)

The distribution of neurons expressing calcium-permeable AMPA receptors in the superficial laminae of the spinal cord dorsal horn. (6/2206)

The superficial dorsal horn is a major site of termination of nociceptive primary afferents. Fast excitatory synaptic transmission in this region is mediated mainly by release of glutamate onto postsynaptic AMPA and NMDA receptors. NMDA receptors are known to be Ca2+-permeable and to provide synaptically localized Ca2+ signals that mediate short-term and long-term changes in synaptic strength. Less well known is a subpopulation of AMPA receptors that is Ca2+-permeable and has been shown to be synaptically localized on dorsal horn neurons in culture (Gu et al., 1996) and expressed by dorsal horn neurons in situ (Nagy et al., 1994; Engelman et al., 1997). We used kainate-induced cobalt uptake as a functional marker of neurons expressing Ca2+-permeable AMPA receptors and combined this with markers of nociceptive primary afferents in the postnatal rat dorsal horn. We have shown that cobalt-positive neurons are located in lamina I and outer lamina II, a region strongly innervated by nociceptors. These cobalt-positive neurons colocalize with afferents labeled by LD2, and with the most dorsal region of capsaicin-sensitive and IB4- and LA4-positive afferents. In contrast, inner lamina II has a sparser distribution of cobalt-positive neurons. Some lamina I neurons expressing the NK1 receptor, the receptor for substance P, are also cobalt positive. These neurons are likely to be projection neurons in the nociceptive pathway. On the basis of all of these observations, we propose that Ca2+-permeable AMPA receptors are localized to mediate transmission of nociceptive information.  (+info)

EPR characterization of axial bond in metal center of native and cobalt-substituted guanylate cyclase. (7/2206)

The nature of the metal-proximal base bond of soluble guanylate cyclase from bovine lung was examined by EPR spectroscopy. When the ferrous enzyme was mixed with NO, a new species was transiently produced and rapidly converted to a five-coordinate ferrous NO complex. The new species exhibited the EPR signal of six-coordinate ferrous NO complex with a feature of histidine-ligated heme. The histidine ligation was further examined by using the cobalt protoporphyrin IX-substituted enzyme. The Co2+-substituted enzyme exhibited EPR signals of a broad g perpendicular;1 component and a g;1 component with a poorly resolved triplet of 14N superhyperfine splittings, which was indicative of the histidine ligation. These EPR features were analogous to those of alpha-subunits of Co2+-hemoglobin in tense state, showing a tension on the iron-histidine bond of the enzyme. The binding of NO to the Co2+-enzyme markedly stimulated the cGMP production by forming the five-coordinate NO complex. We found that N3- elicited the activation of the ferric enzyme by yielding five-coordinate high spin N3- heme. These results indicated that the activation of the enzymes was initiated by NO binding to the metals and proceeded via breaking of the metal-histidine bonds, and suggested that the iron-histidine bond in the ferric enzyme heme was broken by N3- binding.  (+info)

Inhibition of hypoxia-inducible factor 1 activation by carbon monoxide and nitric oxide. Implications for oxygen sensing and signaling. (8/2206)

It has been proposed that cells sense hypoxia by a heme protein, which transmits a signal that activates the heterodimeric transcription factor hypoxia-inducible factor 1 (HIF-1), thereby inducing a number of physiologically relevant genes such as erythropoietin (Epo). We have investigated the mechanism by which two heme-binding ligands, carbon monoxide and nitric oxide, affect oxygen sensing and signaling. Two concentrations of CO (10 and 80%) suppressed the activation of HIF-1 and induction of Epo mRNA by hypoxia in a dose-dependent manner. In contrast, CO had no effect on the induction of HIF-1 activity and Epo expression by either cobalt chloride or the iron chelator desferrioxamine. The affinity of CO for the putative sensor was much lower than that of oxygen (Haldane coefficient, approximately 0.5). Parallel experiments were done with 100 microM sodium nitroprusside, a nitric oxide donor. Both NO and CO inhibited HIF-1 DNA binding by abrogating hypoxia-induced accumulation of HIF-1alpha protein. Moreover, both NO and CO specifically targeted the internal oxygen-dependent degradation domain of HIF-1alpha, and also repressed the C-terminal transactivation domain of HIF-1alpha. Thus, NO and CO act proximally, presumably as heme ligands binding to the oxygen sensor, whereas desferrioxamine and perhaps cobalt appear to act at a site downstream.  (+info)

Cobalt is a chemical element with the symbol Co and atomic number 27. It is a hard, silver-white, lustrous, and brittle metal that is found naturally only in chemically combined form, except for small amounts found in meteorites. Cobalt is used primarily in the production of magnetic, wear-resistant, and high-strength alloys, as well as in the manufacture of batteries, magnets, and pigments.

In a medical context, cobalt is sometimes used in the form of cobalt-60, a radioactive isotope, for cancer treatment through radiation therapy. Cobalt-60 emits gamma rays that can be directed at tumors to destroy cancer cells. Additionally, small amounts of cobalt are present in some vitamin B12 supplements and fortified foods, as cobalt is an essential component of vitamin B12. However, exposure to high levels of cobalt can be harmful and may cause health effects such as allergic reactions, lung damage, heart problems, and neurological issues.

Cobalt radioisotopes are radioactive forms of the element cobalt, which are used in various medical applications. The most commonly used cobalt radioisotope is Cobalt-60 (Co-60), which has a half-life of 5.27 years.

Co-60 emits gamma rays and beta particles, making it useful for radiation therapy to treat cancer, as well as for sterilizing medical equipment and food irradiation. In radiation therapy, Co-60 is used in teletherapy machines to deliver a focused beam of radiation to tumors, helping to destroy cancer cells while minimizing damage to surrounding healthy tissue.

It's important to note that handling and disposal of cobalt radioisotopes require strict safety measures due to their radioactive nature, as they can pose risks to human health and the environment if not managed properly.

Cobalt isotopes are variants of the chemical element Cobalt (Co) that have different numbers of neutrons in their atomic nuclei. This results in the different isotopes having slightly different masses and varying levels of stability.

The most naturally occurring stable cobalt isotope is Co-59, which contains 27 neutrons in its nucleus. However, there are also several radioactive isotopes of cobalt, including Co-60, which is a commonly used medical and industrial radioisotope.

Co-60 has 30 neutrons in its nucleus and undergoes beta decay, emitting gamma rays and becoming Nickel-60. It has a half-life of approximately 5.27 years, making it useful for a variety of applications, including cancer treatment, industrial radiography, and sterilization of medical equipment.

Other radioactive isotopes of cobalt include Co-57, which has a half-life of 271.8 days and is used in medical imaging, and Co-56, which has a half-life of just 77.2 seconds and is used in research.

I'm sorry for any confusion, but "Nickel" is not a medical term. It is a chemical element with the symbol Ni and atomic number 28. Nickel is a hard, silvery-white lustrous metal with a slight golden tinge. It is one of four elements that are ferromagnetic and is used as a common component in various alloys due to its properties such as resistance to corrosion and heat.

However, in a medical context, nickel may refer to:

* Nickel allergy: A type of allergic contact dermatitis caused by an immune system response to the presence of nickel in jewelry, clothing fasteners, or other items that come into contact with the skin. Symptoms can include redness, itching, and rash at the site of exposure.
* Nickel carbonyl: A highly toxic chemical compound (Ni(CO)4) that can cause respiratory and neurological problems if inhaled. It is produced during some industrial processes involving nickel and carbon monoxide and poses a health risk to workers if proper safety measures are not taken.

If you have any concerns about exposure to nickel or symptoms related to nickel allergy, it's best to consult with a healthcare professional for further evaluation and treatment.

Chromium is an essential trace element that is necessary for human health. It is a key component of the glucose tolerance factor, which helps to enhance the function of insulin in regulating blood sugar levels. Chromium can be found in various foods such as meat, fish, whole grains, and some fruits and vegetables. However, it is also available in dietary supplements for those who may not get adequate amounts through their diet.

The recommended daily intake of chromium varies depending on age and gender. For adults, the adequate intake (AI) is 20-35 micrograms per day for women and 35-50 micrograms per day for men. Chromium deficiency is rare but can lead to impaired glucose tolerance, insulin resistance, and increased risk of developing type 2 diabetes.

It's important to note that while chromium supplements are marketed as a way to improve insulin sensitivity and blood sugar control, there is limited evidence to support these claims. Moreover, excessive intake of chromium can have adverse effects on health, including liver and kidney damage, stomach irritation, and hypoglycemia. Therefore, it's recommended to consult with a healthcare provider before taking any dietary supplements containing chromium.

Chromium alloys are materials made by combining chromium with other metals, such as nickel, cobalt, or iron. The addition of chromium to these alloys enhances their properties, making them resistant to corrosion and high temperatures. These alloys have a wide range of applications in various industries, including automotive, aerospace, and medical devices.

Chromium alloys can be classified into two main categories: stainless steels and superalloys. Stainless steels are alloys that contain at least 10.5% chromium by weight, which forms a passive oxide layer on the surface of the material, protecting it from corrosion. Superalloys, on the other hand, are high-performance alloys designed to operate in extreme environments, such as jet engines and gas turbines. They contain significant amounts of chromium, along with other elements like nickel, cobalt, and molybdenum.

Chromium alloys have several medical applications due to their excellent properties. For instance, they are used in surgical instruments, dental implants, and orthopedic devices because of their resistance to corrosion and biocompatibility. Additionally, some chromium alloys exhibit superelasticity, a property that allows them to return to their original shape after being deformed, making them suitable for use in stents and other medical devices that require flexibility and durability.

Protoporphyrins are organic compounds that are the immediate precursors to heme in the porphyrin synthesis pathway. They are composed of a porphyrin ring, which is a large, complex ring made up of four pyrrole rings joined together, with an acetate and a propionate side chain at each pyrrole. Protoporphyrins are commonly found in nature and are important components of many biological systems, including hemoglobin, the protein in red blood cells that carries oxygen throughout the body.

There are several different types of protoporphyrins, including protoporphyrin IX, which is the most common form found in humans and other animals. Protoporphyrins can be measured in the blood or other tissues as a way to diagnose or monitor certain medical conditions, such as lead poisoning or porphyrias, which are rare genetic disorders that affect the production of heme. Elevated levels of protoporphyrins in the blood or tissues can indicate the presence of these conditions and may require further evaluation and treatment.

In the context of medicine, there is no specific medical definition for 'metals.' However, certain metals have significant roles in biological systems and are thus studied in physiology, pathology, and pharmacology. Some metals are essential to life, serving as cofactors for enzymatic reactions, while others are toxic and can cause harm at certain levels.

Examples of essential metals include:

1. Iron (Fe): It is a crucial component of hemoglobin, myoglobin, and various enzymes involved in energy production, DNA synthesis, and electron transport.
2. Zinc (Zn): This metal is vital for immune function, wound healing, protein synthesis, and DNA synthesis. It acts as a cofactor for over 300 enzymes.
3. Copper (Cu): Copper is essential for energy production, iron metabolism, antioxidant defense, and connective tissue formation. It serves as a cofactor for several enzymes.
4. Magnesium (Mg): Magnesium plays a crucial role in many biochemical reactions, including nerve and muscle function, protein synthesis, and blood pressure regulation.
5. Manganese (Mn): This metal is necessary for bone development, protein metabolism, and antioxidant defense. It acts as a cofactor for several enzymes.
6. Molybdenum (Mo): Molybdenum is essential for the function of certain enzymes involved in the metabolism of nucleic acids, proteins, and drugs.
7. Cobalt (Co): Cobalt is a component of vitamin B12, which plays a vital role in DNA synthesis, fatty acid metabolism, and nerve function.

Examples of toxic metals include:

1. Lead (Pb): Exposure to lead can cause neurological damage, anemia, kidney dysfunction, and developmental issues.
2. Mercury (Hg): Mercury is highly toxic and can cause neurological problems, kidney damage, and developmental issues.
3. Arsenic (As): Arsenic exposure can lead to skin lesions, cancer, neurological disorders, and cardiovascular diseases.
4. Cadmium (Cd): Cadmium is toxic and can cause kidney damage, bone demineralization, and lung irritation.
5. Chromium (Cr): Excessive exposure to chromium can lead to skin ulcers, respiratory issues, and kidney and liver damage.

Heavy metals are a group of elements with a specific gravity at least five times greater than that of water. They include metals such as mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb). These metals are considered toxic when they accumulate in the body beyond certain levels, interfering with various biological processes and causing damage to cells, tissues, and organs.

Heavy metal exposure can occur through various sources, including occupational exposure, contaminated food, water, or air, and improper disposal of electronic waste. Chronic exposure to heavy metals has been linked to several health issues, such as neurological disorders, kidney damage, developmental problems, and cancer. Monitoring and controlling exposure to these elements is essential for maintaining good health and preventing potential adverse effects.

Porphyrins are complex organic compounds that contain four pyrrole rings joined together by methine bridges (=CH-). They play a crucial role in the biochemistry of many organisms, as they form the core structure of various heme proteins and other metalloproteins. Some examples of these proteins include hemoglobin, myoglobin, cytochromes, and catalases, which are involved in essential processes such as oxygen transport, electron transfer, and oxidative metabolism.

In the human body, porphyrins are synthesized through a series of enzymatic reactions known as the heme biosynthesis pathway. Disruptions in this pathway can lead to an accumulation of porphyrins or their precursors, resulting in various medical conditions called porphyrias. These disorders can manifest as neurological symptoms, skin lesions, and gastrointestinal issues, depending on the specific type of porphyria and the site of enzyme deficiency.

It is important to note that while porphyrins are essential for life, their accumulation in excessive amounts or at inappropriate locations can result in pathological conditions. Therefore, understanding the regulation and function of porphyrin metabolism is crucial for diagnosing and managing porphyrias and other related disorders.

Cobamides are a class of compounds that are structurally related to vitamin B12 (cobalamin). They consist of a corrin ring, which is a large heterocyclic ring made up of four pyrrole rings, and a cobalt ion in the center. The lower axial ligand of the cobalt ion can be a variety of different groups, including cyano, hydroxo, methyl, or 5'-deoxyadenosyl groups.

Cobamides are involved in a number of important biological processes, including the synthesis of amino acids and nucleotides, the metabolism of fatty acids and cholesterol, and the regulation of gene expression. They function as cofactors for enzymes called cobamide-dependent methyltransferases, which transfer methyl groups (CH3) from one molecule to another.

Cobamides are found in a wide variety of organisms, including bacteria, archaea, and eukaryotes. In humans, the most important cobamide is vitamin B12, which is essential for the normal functioning of the nervous system and the production of red blood cells. Vitamin B12 deficiency can lead to neurological problems and anemia.

Vitamin B12, also known as cobalamin, is a water-soluble vitamin that plays a crucial role in the synthesis of DNA, formation of red blood cells, and maintenance of the nervous system. It is involved in the metabolism of every cell in the body, particularly affecting DNA regulation and neurological function.

Vitamin B12 is unique among vitamins because it contains a metal ion, cobalt, from which its name is derived. This vitamin can be synthesized only by certain types of bacteria and is not produced by plants or animals. The major sources of vitamin B12 in the human diet include animal-derived foods such as meat, fish, poultry, eggs, and dairy products, as well as fortified plant-based milk alternatives and breakfast cereals.

Deficiency in vitamin B12 can lead to various health issues, including megaloblastic anemia, fatigue, neurological symptoms such as numbness and tingling in the extremities, memory loss, and depression. Since vitamin B12 is not readily available from plant-based sources, vegetarians and vegans are at a higher risk of deficiency and may require supplementation or fortified foods to meet their daily requirements.

Tungsten compounds refer to chemical substances that contain tungsten (W, atomic number 74) in its ionic or molecular form. Tungsten is a heavy metal and exists in several oxidation states, most commonly +6, +4, and +2. Tungsten compounds have various applications in industrial, medical, and technological fields.

Examples of tungsten compounds include:

* Tungstic acid (WO3·2H2O)
* Sodium polytungstate (Na6WO6)
* Calcium tungstate (CaWO4)
* Tungsten carbide (WC)
* Tungsten hexafluoride (WF6)

Tungsten compounds have been used in medical imaging, such as X-ray machines and CT scanners, due to their high density and ability to absorb X-rays. They are also used in the production of surgical instruments, dental alloys, and other medical devices. However, some tungsten compounds can be toxic or carcinogenic, so proper handling and disposal are essential.

Zinc is an essential mineral that is vital for the functioning of over 300 enzymes and involved in various biological processes in the human body, including protein synthesis, DNA synthesis, immune function, wound healing, and cell division. It is a component of many proteins and participates in the maintenance of structural integrity and functionality of proteins. Zinc also plays a crucial role in maintaining the sense of taste and smell.

The recommended daily intake of zinc varies depending on age, sex, and life stage. Good dietary sources of zinc include red meat, poultry, seafood, beans, nuts, dairy products, and fortified cereals. Zinc deficiency can lead to various health problems, including impaired immune function, growth retardation, and developmental delays in children. On the other hand, excessive intake of zinc can also have adverse effects on health, such as nausea, vomiting, and impaired immune function.

Corrinoids are a class of compounds that include vitamin B12 and its analogs. Vitamin B12 is an essential nutrient for humans and other animals, playing a critical role in the synthesis of DNA, the maintenance of the nervous system, and the metabolism of fatty acids and amino acids.

The corrinoid ring is the structural backbone of vitamin B12 and its analogs. It is a complex, planar molecule made up of four pyrrole rings joined together in a macrocycle. The corrinoid ring contains a central cobalt ion, which can form coordination bonds with various ligands, including organic groups such as methyl, hydroxo, and cyano.

Corrinoids can be found in a wide variety of foods, including meat, dairy products, fish, eggs, and some fortified plant-based foods. They are also produced by certain bacteria, which can synthesize the corrinoid ring and the cobalt ion de novo. Some corrinoids have biological activity similar to vitamin B12, while others do not.

In addition to their role in human nutrition, corrinoids are also used in industrial applications, such as the production of antibiotics and other pharmaceuticals. They are also used as catalysts in chemical reactions, due to their ability to form stable coordination complexes with various ligands.
