The structure of solid NaCN is related to that of sodium chloride.[5] The anions and cations are each six-coordinate. Potassium cyanide (KCN) adopts a similar structure. Each Na+ forms pi-bonds to two CN− groups as well as two "bent" Na---CN and two "bent" Na---NC links.[6] Because the salt is derived from a weak acid, sodium cyanide readily reverts to HCN by hydrolysis; the moist solid emits small amounts of hydrogen cyanide, which smells like bitter almonds (not everyone can smell it-the ability thereof is due to a genetic trait[7]). Sodium cyanide reacts rapidly with strong acids to release hydrogen cyanide. This dangerous process represents a significant risk associated with cyanide salts. It is detoxified most efficiently with hydrogen peroxide (H2O2) to produce sodium cyanate (NaOCN) and water:[4] ...

According to information prosecutors presented in court, sometime before the spring of 2003, Krar accumulated a large quantity of sodium cyanide and acids such as hydrochloric, nitric and acetic acids. The chemicals were found last April after the discovery of false documents belonging to Krar. The false documents were part of a package Krar mailed to Edward Feltus in New Jersey in January 2002. Instead of being delivered to Feltus as Krar intended, the package was accidentally taken to a household on Staten Island, New York. The package contained more than five false identification documents, including a North Dakota birth certificate, a Social Security card, a Vermont birth certificate, a Defense Intelligence Agency Identification card, and a United Nations Multinational Force Identification card. The subsequent investigation determined that Krar not only possessed false documents, but had accumulated dangerous chemical weapons. Sodium cyanide is a toxic chemical by itself and as such ...

The surface of rat visceral yolk sacs (VYS) of intact, viable rat conceptuses were continuously monitored with a microfiberoptic sensor optimized for detection of the reduced pyridine nucleotides, NADH and NADPH. Model chemical toxins, cyanide and alloxan, were used and evaluated on the basis of their differential ability to modulate NAD(H)- and NADP(H)-dependent cellular pathways, respectively. Exposure with 2 mM sodium cyanide for 5 min caused a reversible fluorescence increase of 325 arbitrary fluorescence units (AFU) and 225 AFU on Gestational Days (GD) 10 and 11, respectively. Exposure with 40 mM alloxan for 5 min resulted in a fluorescence decrease of 170 and 120 AFU on GD 10 and 11, respectively. Glutathione (GSH) levels in the VYS, as determined by HPLC, showed a marked decrease from 27.3 +/- 2.1 to 2.9 +/- 0.4 pmol/mg protein, within the 5-min alloxan exposure period on GD 10. No decrease in GSH levels was noted for the same exposure duration on GD 11. A 2-hr pretreatment with 25 microM BCNU [

Sodium cyanide (NaCN) ejectors for coyotes (Canis latrans), known as M-44s, are used in many parts of the United States for lethally removing coyotes to protect livestock or other resources. Quantifying selectivity of current devices in killing target and non-target species is important to users and provides a baseline for future development of more effective and selective techniques. We used motion-activated cameras to monitor M-44 locations for coyote and other species visitations to the sites. Because camera presence potentially influences coyote behavior, we first compared activation of M-44s at paired sites where cameras were and were not present. Coyotes activated M-44s sites with cameras (n = 17) similarly to sites without cameras (n = 19). During 832 site-days of observation, coyotes visited M-44 sites 29 times, and 18 other species visited 1,597 times. The mean visitation ratio for non-coyotes to coyotes was 2.8:1 at the M-44 locations monitored (n = 22). Non-coyotes were much less ...
Environmental groups had blasted the agencys preliminary decision reauthorizing the cyanide traps, saying they were impossible to use safely.
The benzoin condensation is a reaction (often called a condensation reaction, for historical reasons) between two aromatic aldehydes, particularly benzaldehyde. The reaction is catalyzed by a nucleophile such as the cyanide anion or an N-heterocyclic carbene. The reaction product is an aromatic acyloin with benzoin as the parent compound. An early version of the reaction was developed in 1832 by Justus von Liebig and Friedrich Woehler during their research on bitter almond oil. The catalytic version of the reaction was developed by Nikolay Zinin in the late 1830s, and the reaction mechanism for this organic reaction was proposed in 1903 by A. J. Lapworth. In the first step in this reaction, the cyanide anion (as sodium cyanide) reacts with the aldehyde in a nucleophilic addition. Rearrangement of the intermediate results in polarity reversal of the carbonyl group, which then adds to the second carbonyl group in a second nucleophilic addition. Proton transfer and elimination of the cyanide ion ...

An emergency involving the diagnosis and management of patients exposed to cyanide is a potential scenario for any healthcare facility. Cyanide exposure is associated with smoke inhalation, laboratory mishaps, industrial incidents, suicide attempts, and criminal activity. Cyanide is a chemical group that consists of one atom of carbon bound to one atom of nitrogen by three molecular bonds (C≡N). Inorganic cyanides (also know as cyanide salts) contain cyanide in the anion form (CN−) and are used in numerous industries, such as metallurgy, photographic developing, plastic manufacturing, fumigation, and mining. Common cyanide salts include sodium cyanide (NaCN) and potassium cyanide (KCN). Sodium salts react readily with water to form hydrogen cyanide. Organic compounds that have a cyano group bonded to an alkyl residue are called nitriles. For example, methyl cyanide is also known as acetonitrile (CH3CN). Hydrogen cyanide (HCN) is a colorless gas at standard temperature and pressure with a ...
The studies of Deltombe, Gail at al., ECETOC 2007 Report and Ricca et al. are reliable study reports and could be used for a "Weight‐of‐Evidence" approach with validity 2 (study with minor deficits and not performed according to GLP principles) to describe the performance of hydrolysis of Sodium cyanide (NaCN) or Potassium cyanide (KCN) under alkaline conditions. We concluded that according to the used literature the full test of Guideline OECD 111 study should not be performed on pH 4, 7 and 9 because of the instability of Potassium cyanide in water at pH 4 and 7 and release and high vapor pressure of HCN. We propose to use the results from literature of Deltombe, Gail and Ricca to describe the performance of hydrolysis of Potassium cyanide (KCN) under alkaline conditions. ...
Even given all of these direct and indirect effects of cyanide exposure to plants, it is highly unlikely for humans to be exposed to large enough amounts of cyanide to be put at risk; still, its important to know the signs of cyanide exposure just to err on the side of caution. The earliest effects of cyanide exposure are rapid, deep breathing and shortness of breath followed by convulsions (seizures) and loss of consciousness. Prolonged exposure to small amounts of cyanide over long periods of time has been linked to breathing difficulties, chest pain, vomiting, blood changes, headaches and enlargement of the thyroid gland. Exposure to large amounts of cyanide in a short time can cause brain and heart damage and in some cases can lead to coma and death.. ...

Afferent chemoreceptor activity was recorded from the peripheral cut end of the carotid sinus nerve in pentobarbitone anaesthetized cats. The effects of purines, peptides and ouabain on chemosensory activity were studied. Purines. It was found that intracarotid injections of adenosine: AMP; ADP; ATP; CoA;Me-adenosine analogues: N6-methyladenosine, 2-chloroadenosine, 3-deoxyudenosine but not 2-deoxyadenosine; cyclic AMP; dibutyryl cyclic AMP increased spontaneous chemoreceptor discharge. The ATP analogues, a-5- methylene ATP decreased spontaneous chemoreceptor discharge, whereas the f-y-methylene ATP caused a slight increase in discharge. Adenine and the purine nucleosides inosine and guanosine had little or no effect on the discharge. The pyrimidine nucleosides cytidine and uridine were also studied and had little or no effect on spontaneous chemoreceptor discharge. Intracarotid injection of theophylline transiently depressed spontaneous chemosensory activity and potentiated the action of ...
Increased sympathetic activity is a well-known pathophysiological mechanism in insulin resistance (IR) and hypertension (HT). The carotid bodies (CB) are peripheral chemoreceptors that classically respond to hypoxia by increasing chemosensory activity in the carotid sinus nerve (CSN), causing hyperventilation and activation of the sympathoadrenal system. Besides its role in the control of ventilation, the CB has been proposed as a glucose sensor implicated in the control of energy homeostasis. However, to date no studies have anticipated its role in the development of IR. Herein, we propose that CB overstimulation is involved in the etiology of IR and HT, core metabolic and hemodynamic disturbances of highly prevalent diseases like the metabolic syndrome, type 2 diabetes, and obstructive sleep apnoea. We demonstrate that CB activity is increased in IR animal models and that CSN resection prevents CB overactivation and diet-induced IR and HT. Moreover, we show that insulin triggers CB, ...
The carotid body (CB) is the main arterial chemoreceptor in charge of adjusting ventilatory and cardiovascular function during changes in arterial blood gases. Regardless this essential function, the CB has been implicated in the sensing of other physiological signals such as changes in blood flow and glucose levels. More important, malfunction of the CB chemoreceptors has been associated with the progression and deterioration of several disease states such as hypertension, heart failure, renal failure, insulin resistance, diabetes and sleep apnea. Although the mechanisms involved in the alterations of the CB function in pathophysiology are currently under intense research, the development of therapeutic approaches to restore normal CB chemoreflex function remains unsolved. Recently, elegant studies showing the effect of CB neurotomy in pathophysiology have unveiled a key role of these arterial chemoreceptors in the development of autonomic imbalance and respiratory disturbances, and suggest that
Purpose. Grade 3 NENs are aggressive tumours with poor prognosis. PRRT+/− radiosensitising chemotherapy is a potential treatment for disease with high somatostatin receptor (SSTR) expression without spatially discordant FDG-avid disease. We retrospectively evaluated the efficacy of PRRT in G3 NEN.. Methods. Kaplan-Meier estimation was used to determine progression-free survival (PFS) and overall survival (OS) defined from start of PRRT. Subgroup analysis was performed for patients with Ki-67 ≤ 55% and ,55%. Anatomical response (RECIST 1.1) and toxicity 3 months after PRRT was determined. Disease control rate (DCR) was defined as complete response (CR), partial response (PR) and stable disease (SD) of those with prior progression.. Results. 28 patients (M = 17; age 16-78 years; Ki-67 ≤ 55% = 22) were reviewed. 17 patients had pancreatic, 5 small bowel, 3 large bowel, 2 bronchial and 1 unknown primary disease. 25/28 had significant FDG-avid disease prior to treatment. Most had ...

Sorry about the loss of your pet. Although my experience is with the inhalation of cyanide, I would think that if your dog ingested cyanide and it died suddenly, it was an acute poisoning of cyanide (which can be found in pest control media like rat poison). If it was acute and dog was probably exibiting convulsions, frothing at the mouth, and respiratory problems. If this was the case, a simple blood test can confirm the presence of cyanide. If it was chronic cyanide poisoning (a little cyanide ingested over a long period of time), hair and nail samples can be taken to prove cyanide poisoning. Most likely, it was an acute ingestion - but I would also check with your vet and examine the lab tests that were run (if any). One sign of ethylene glycol poisoning (anti-freeze) is kidney failure and that may be another way your pet was poisoned. Good Luck, Kelly Dennison Industrial Hygienist ...

The effects of cyanide on Ca2+ exchange in isolated ventricular myocytes and on the intracellular concentrations of Ca2+, Na+ and H+ have been investigated to assess the contribution that mitochondria might play in cellular Ca2+ metabolism. Ionic levels were measured with ion-selective electrodes. KCN (2.5 mM) inhibited a component of Ca2+ exchange in myocytes that could be attributed to mitochondrial exchange, but was without effect on non-mitochondrial Ca2+ exchange. NaCN (2.5 mM) caused a transient reduction of [H+]i, [Na+]i and [Ca2+]i when applied to the superfusate bathing ventricular trabeculae or papillary muscles. The transient changes of [Na+]i were accentuated when the preparation was exposed to a solution which would be expected to increase the cellular calcium content. The reduction of [Na+]i which accompanies a reduction of the extracellular sodium concentration, [Na]o, was attenuated in the presence of NaCN, but the intracellular acidosis resulting from a reduction of [Na]o was ...
The mechanism of oxygen sensing in arterial chemoreceptors is unknown but has often been linked to mitochondrial function. A common criticism of this hypothesis is that mitochondrial function is insensitive to physiological levels of hypoxia. Here we investigate the effects of hypoxia (down to 0.5% O2) on mitochondrial function in neonatal rat type-1 cells. The oxygen sensitivity of mitochondrial [NADH] was assessed by monitoring autofluorescence and increased in hypoxia with a P50 of 15 mm Hg (1 mm Hg = 133.3 Pa) in normal Tyrode or 46 mm Hg in Ca(2+)-free Tyrode. Hypoxia also depolarised mitochondrial membrane potential (m, measured using rhodamine 123) with a P50 of 3.1, 3.3 and 2.8 mm Hg in normal Tyrode, Ca(2+)-free Tyrode and Tyrode containing the Ca(2+) channel antagonist Ni(2+), respectively. In the presence of oligomycin and low carbonyl cyanide 4-(trifluoromethoxy) phenylhydrazone (FCCP; 75 nm) m is maintained by electron transport working against an artificial proton leak. Under these

In DG cultures exposed to 10 mM NaCN for 45 min, ≈90% of neurons (identified by immunoreactivity against NeuN, a neuronal marker) died 24 h after hypoxia, because they stained with propidium iodide. Survival of GFAP-immunoreactive glia was not affected (data not shown). Combining the same cyanide treatment with glucose deprivation ("ischemia") had very similar effects on the neurons. By EM, many hypoxic neurons showed early swelling of mitochondria and endoplasmic reticulum, in the presence of an intact nucleus (Fig. 1B), and evolved later toward necrosis with severe cytoplasmic swelling and membrane rupture (Fig. 1C). This finding was in sharp contrast to staurosporine-treated apoptotic neurons, which displayed nuclear breakdown into large, round masses of chromatin (Fig. 1D). Hypoxic necrosis evolved rapidly: we observed a progressive loss of the mitochondrial membrane potential Δψ within a few minutes of cyanide application (Fig. 2 A-D). This Δψ decay was always synchronous with release ...
