ABSTRACT
Wild mushroom poisoning is often reported to cause acute liver or renal failure. However, acute rhabdomyolysis caused by wild mushroom poisoning has rarely been reported. We describe 7 patients of 1 family with Russula subnigricans Hongo poisoning. Their clinical manifestations varied from gastrointestinal symptoms to rhabdomyolysis, with 1 fatality. Our report provides supporting evidence that rhabdomyolysis may result from ingestion of R subnigricans mushrooms. A key to survival for patients with rhabdomyolysis caused by R subnigricans poisoning may be early recognition and intensive supportive care.

Interactions between amines and carbon dioxide (CO2) are essential to amine-functionalized solid adsorbents for carbon capture, and an in-depth knowledge of these interactions is crucial to adsorbent design and fabrication as well as adsorption/desorption processes. The local structures of CO2 adsorbed on a tetraethylenepentamine-impregnated mesoporous silica SBA-15 were investigated by solid-state (13)C{(14)N} S-RESPDOR MAS NMR technique and theoretical DFT calculations. Two types of adsorption species, namely, secondary and tertiary carbamates as well as distant ammonium groups were identified together with their relative concentrations and relevant (14)N quadrupolar parameters. Moreover, a dipolar coupling of 716 Hz was derived, corresponding to a (13)C-(14)N internuclear distance of 1.45 Å. These experimental data are in excellent agreement with results obtained from DFT calculations, revealing that the distribution of surface primary and secondary amines readily dictates the CO2 adsorption/desorption properties of the adsorbent.
