Human poisoning caused by ingestion of unripe fruit of Passiflora ade/lOpoda is he re reported, apparently for the first time. HCN is pl'Ocluced in the pericarp and aril of tbe unripe fruit, as well as in tbe primary stem, petiole, br;¡cts and stipules but not in tendrils. HCN yield has been reported previously in Passifloraceae only from vegetative parts. The pericarp and arils of complctely r...

New millimeter-wave CO and HCN observations of the host galaxies of infrared-excess Palomar Green quasi-stellar objects (PG QSOs) previously detected in CO are presented. These observations are designed to assess the validity of using the infrared luminosity to estimate star formation rates of luminous AGN by determining the relative significance of dust-heating by young, massive stars and acti...

Abstract Plant responses to pathogens comprise a complex process, implying plethora of signals and reactions. Among them, endogenous production hydrogen cyanide (HCN) has been shown induce resistance in Arabidopsis the hemibiotrophic bacterium Pseudomonas syringae pv. tomato (Pst) DC3000. ?-cyanoalanine synthase (CAS-C1) is responsible for detoxification HCN mitochondria. Here, we show that gre...

The architecture and operation of a trace hydrogen cyanide (HCN) gas sensor based on quartz-enhanced photo-acoustic spectroscopy and using a λ = 1.53 µm telecommu-nication diode laser are described. The influence of humidity content in the analyzed gas on the sensor performance is investigated. A kinetic model describing the vibrational to translational (V–T) energy transfer following the laser...

abstract fluorescens pseudomonads can suppress soil-borne plant pathogens by employing several mechanisms such as competition for iron by means of siderophores. three indigenous strains pseudomonas fluorescens (utpf5, utpf61 and utpf76), pseudomonas aeruginosa 7nsk2 and its pyoverdin mutant, mpfm1, were used for investigation the effect of iron competition on bean damping-off suppression. the r...

The hyperpolarization-activated, cyclic nucleotide-modulated (HCN) channel gene family is known to contribute significantly to cardiac pacemaking via pacemaker currents. To date, there are four mammalian HCN isoforms (HCN1–4) identified. The importance of HCN channel function to normal cardiac automaticity in mice was recently corroborated in humans diagnosed with idiopathic sinus node dysfunct...

Overactivation of hyperpolarization-activated cyclic nucleotide-gated (HCN) channels is involved in diabetes-depressed excitability of aortic baroreceptor neurons in nodose ganglia. This involvement links to the autonomic dysfunction associated with high morbidity and mortality in diabetic patients. The present study examined the effects of an angiotensin II type I receptor (AT(1)R) antagonist ...

In this study, sewage sludge and mycelial waste from antibiotic production were pyrolyzed in a batch scale fixed-bed reactor as examples of two kinds of typical industrial biomass wastes with high nitrogen content. A series of experiments were conducted on the rapid pyrolysis and the slow pyrolysis of these wastes in the temperature range from 500–800 °C to investigate the Fuel-N transformation...

In this research, we aim to directly measure the specific activity (SA) of the carbon-11 cyanide ([(11)C]CN¯) produced by our in-house built automated [(11)C]HCN production system and to identify the major sources of (12)C-cyanide ((12)CN¯). The [(11)C]CN¯ is produced from [(11)C]CO2, which is generated by the (14)N(p,α)(11)C nuclear reaction using a cyclotron. Direct measurement of cyanide con...

The metabolism of linamarin [2(beta-D-glucopyranosyloxy)isobutyronitrile] was investigated in male albino Wistar rats and using rat liver microsomal preparations. In the in vitro experiments incubations of varying concentrations of linamarin at pH 6.0-6.5 with liver microsomal preparations resulted in rapid degradation of the substrate without concomitant production of any detectable amount of ...
