Cyanide-resistant O(2) consumption can be stimulated by either treating whole white potato tubers (Norchip) with ethylene, in the presence of 100% O(2), or aging slices obtained from untreated potato tubers. A comparison of alternative pathway activity elicited by either treatment was undertaken. The proportion of electrons flowing through the alternative path in the presence of intermediate co...

The respiration of T. cruzi epimastigotes was studied using KCN (1 mM) and NaN3 (5 mM) as inhibitors and glucose (33 mM) as substrate. NaN3 inhibits 18% and KCN 58% of the oxygen uptake when T. cruzi cultures enter the stationary phase. The azide-inhibition pattern closely follows endogenous respiration pattern throughout the different growth phases. Titration of the oxygen uptake with cyanide ...

The effects of KCN, antimycin A, malonate, rotenone, and amytal on the oxidation of malate, succinate, and extramitochondrial reduced nicotinamide adenosine dinucleotide (NADH) by corn mitochondria were studied. Potassium cyanide and antimycin A inhibited the oxidation of all three substrates. Rotenone and amytal inhibited only the oxidation of malate, and malonate inhibited only the oxidation ...

1. Sections of Avena coleoptiles are found to show a considerable elongation when suspended in solutions of growth substance. 2. This elongation does not take place in the absence of O(2) and is inhibited by KCN and phenylurethane. 3. The rate of respiration of sections of coleoptiles is increased by the addition of growth substance in concentrations which cause growth. High concentrations of g...

Abstract Clinical keratoconus (KCN) detection is a challenging and time-consuming task. In the diagnosis process, ophthalmologists must revise demographic clinical ophthalmic examinations. The latter include slit-lamb, corneal topographic maps, Pentacam indices (PI). We propose an Ensemble of Deep Transfer Learning (EDTL) based on maps. consider four pretrained networks, SqueezeNet (SqN), AlexN...

The cardiovascular and acid-base changes following equivalent i.v. bolus doses of sodium nitroprusside (SNP) and potassium cyanide (KCN) have been studied in two groups of anaesthetized dogs. In a third group, the metabolic changes produced by i.v. infusion of SNP 1.5 mg kg-1 at a constant rate over 1 h have been studied. In contrast to a decrease in arterial pressure following SNP, hypertensio...

We have measured ' C and Na NMR spin-lattice relaxation times as a function of temperature in KCN and NaCN'in order to study the head-to-tail reorientations of the CN molecules in the two low-temperature ordered phases. We have combined our data with those of dielectric-response and ionic-thermal-conductivity measurements and have determined the correlation time ~, of the reorientations over mo...

In this paper, an electron transfer reaction mediated by sodium tanshinone IIA sulfonate (STS) was studied in rat heart mitochondria. It was found that STS could stimulate mitochondrial NADH oxidation dose-dependently and partly restore NADH oxidation in the presence of respiratory inhibitor (rotenone or antimycin A or KCN). It was likely that STS could accept electrons from complex I similar t...

Several studies from our group have indicated that the BNST play an important role in baroreflex modulation. However, the involvement of the BNST in the chemoreflex activity is unknown. Thus, in the present study, we investigated the effect of the local bed nucleus of stria terminalis (BNST) neurotransmission inhibition by bilateral microinjections of the non-selective synaptic blocker cobalt c...

Purpose To review the historical background and basic principles of collagen cross-linking, to bring together the data regarding the outcomes and complications of collagen cross-linking and finally to explore the efficacy and safety of new variations of this technique. Methods A literature review was performed using PubMed and Scopus. The following keywords were used for literature search: cr...
