EPR analysis shows that the anion radical of 2,6-dinitrotoluene (DNT) in liquid ammonia exists with the counterion (either K(+) or Na(+)) associated with one of the two nitro groups. This tight association (-NO(2)(*-)M(+)) persists after solvent removal, and it renders the anion radical very susceptible to loss of metal nitrite. The slightest agitation of the solid potassium salt of DNT(*-) leads to detonation, and formation of KNO(2) and polymer (in the solid phase) and CH(4), HCN, H(2), and N(2)O (in the gas phase). Trapping experiments suggest that the methane comes from carbenes, and it is suggested that the HCN comes from an anthranil radical intermediate. The potassium anion radical salts of 1,3-dinitrobenzene, 2,6-dinitrotoluene, 1,3,5-trinitrobenzene, and 2,4,6-trinitrotoluene all readily lose KNO(2), and the ease of C-NO(2)(*-)M(+) bond rupture increases with the degree of nitration. In the cases of the two trinitrated systems dissociation takes place immediately upon anion radical formation in liquid ammonia. This observation is consistent with the fact that only the systems with two nitro groups vicinal to a methyl group yield HCN upon detonation.

Nitrate-nitrite poisoning killed four adult alpacas and induced the abortion of a full-term fetus after access to oaten hay (Avena sativa) containing 3.2% KNO(3) equivalent in dry matter. Necropsy findings were cyanosis, dark-coloured blood, and pulmonary congestion and oedema. Aqueous humour from two adults contained 25 mg NO(3)/L and that from the fetus contained 10 mg NO(3)/L. Cyanide poisoning possibly killed two adult wether alpacas that ate a garden-cultivated variety of Osteospermum ecklonis (South African daisy, bietou) with a cyanide potential of 6800 mg HCN/kg dry matter.

Angiogenesis is critical for the development, progression, and metastasis of hepatocellular carcinoma (HCC), but the roles of miR-3064-5p in HCC angiogenesis are still unknown. In this study, the roles of miR-3064-5p in HCC angiogenesis were studied in 192 HCC patients, xenograft mouse models, and HCC cell lines. The results showed that miR-3064-5p expression was significantly decreased in HCC tissues and cells, and downregulated miR-3064-5p was associated with upregulated angiogenic potential of HCC. MiR-3064-5p inhibited proangiogenic VEGFA and angiogenin expressions but induced antiangiogenic endostatin and MMP12 expressions, finally leading to suppression of HCC angiogenesis, as shown by the decline in intratumoral microvessel density (MVD). Moreover, miR-3064-5p was inversely correlated with lncRNA MALAT1 and FOXA1. FOXA1 bound to and interacted with CD24 and then regulated Src phosphorylation. MiR-3064-5p played an antiangiogenic role by inhibiting the FOXA1/CD24/Src pathway, whereas oncogenic MALAT1 functioned as a competing endogenous RNA (ceRNA) by sponging miR-3064-5p to alleviate the suppressive effect on the FOXA1 pathway. HCC patients with high miR-3064-5p, low MALAT1, or low FOXA1 expression had a better prognosis with longer overall survival and recurrence-free survival. In univariate and multivariate analyses, miR-3064-5p was identified as the independent prognostic predicator for HCC progression and patient survival. Taken together, miR-3064-5p exerts an antiangiogenic role by targeting the FOXA1/CD24/Src pathway but oncogenic lncRNA MALAT1 acts as a ceRNA to sponge miR-3064-5p. MiR-3064-5p is of great clinical significance and is a novel prognostic indicator and an attractive therapeutic target for HCC.
