PURPOSE To report a case of unilateral post trabeculectomy globe massage-induced keratoconus (KCN). CASE REPORT A 52-year-old lady with a history of trabeculectomy due to iridocorneal endothelial syndrome in her right eye was instructed to massage her globe to control gradual rise of intraocular pressure 1.5 years after surgery. The patient experienced high astigmatism and marked inferior cor...

In this paper, the sources of K and Na in vanadium-nitrogen (VN) alloys their effects on furnace structure were studied. The results show that are mainly present as counter-ions decavanadate dodecanadate ammonium polyvanadate (APV) vanadium trioxide (V2O3). production process VN, concentration scab produced kiln is 25 times higher than raw material, 15 degree enrichment stronger Na. Additionall...

The oxidation of cyanide (CN-) to a much less toxic thiocyanate (SCN-) is the main in vivo biochemical pathway for CN- detoxification. SCN- is excreted mainly in urine. This study was performed to investigate the effect of lipoic acid (LA) on the urinary excretion of thiocyanate (SCN-; rhodanate) in rats. Groups of the animals were treated intraperitoneally (i.p.) as follows: group 1: potassium...

The present work was aimed at evaluating the effects of maternal exposure to potassium cyanide (KCN) during lactation in goats. Twenty-seven lactating female goats were orally dosed with 0 (control), 1.0, 2.0, or 3.0 mg KCN/kg body weight/day from lactation days 0 to 90. After this period, all male kids and one mother from each group were killed for a pathological study. Cyanide treatment promo...

in the complexes formed as a consequence of heat treatment. BLG contains five Cys residues and KCN contains 2 Cys residues, and thus there is a large number of combinations of possible disulfide bondings. Reacting reduced KCN with DTNB (dithiobisnitrobenzoic acid) gives KCN molecules containing activated Cys groups. Reacting partially reduced BLG with these derivatives gave a range of products....

We present, for KCN and NaCN in their electrically disordered and ordered low-temperature phases, a microscopic model using interatomic forces of the Born-Mayer type. We calculate with our model the atomic positions, the normal modes, and the elastic constants of KCN and NaCN in their ordered phase. %'e also calculate the atomic positions in the disordered phase. We adjust the parameters of our...

Uncoupling protein 2 (UCP-2) is expressed in the inner mitochondrial membrane and modulates mitochondrial function by partially uncoupling oxidative phosphorylation, and it has been reported to modulate cell death. Cyanide is a potent neurotoxin that inhibits complex IV to alter mitochondrial function to induce neuronal death. In primary rat cortical cells KCN produced an apoptotic death at 200...

Pyridine nucleotide levels in the corneal epithelium were measured using redox fluorometry, a noninvasive method for monitoring the metabolic status of corneal tissue, and a sensitive bioluminescent assay and an improved extraction procedure that allows the simultaneous extraction and measurement of both NADH and NAD. The same corneas were measured using each of the two methods to enable compar...

Two inhibitors of the Calvin-Benson cycle [glycolaldehyde (GA) and potassium cyanide (KCN)] were used in cultured Symbiodinium cells and in nubbins of the coral Pocillopora damicornis to test the hypothesis that inhibition of the Calvin-Benson cycle triggers coral bleaching. Inhibitor concentration range-finding trials aimed to determine the appropriate concentration to generate inhibition of t...

Knowledge on the biosynthetic pathways of the monoterpene alkaloids is enormous, but little is known about their mechanism of transporting system from the plant cell. There is not concrete evidence confirming the role of ABC transporters in the secretion of monoterpene indole alkaloids (MIAs) in Catharanthus roseus. Therefore, in order to determine the role of different transporting systems inv...
