“…A doublet of peaks was observed at 228.99 and 232.15 eV (Δ = 3.16 eV) (Figure E), which correspond to the 3d 5/2 and 3d 3/2 of Mo 4+ , respectively. ,,, Instead, in the post-treatment materials, Mo exists in two oxidation states, Mo 4+ and Mo 6+ (Figure F). The pair of doublets at 229.15 and 231.18 eV and 232.25 and 235.18 eV corresponds to the 3d 5/2 and 3d 3/2 of Mo 4+ and Mo 6+ , respectively (Figure F). , The formation of Mo 6+ in the post-treated sample can be understood by the oxidation of Mo 4+ → Mo 6+ during the gaseous mercury sorption processes in the air …”

Every year, thousands of tons of gaseous mercury are released globally, prompting the World Health Organization (WHO) in 2020 to designate mercury as one of the top 10 chemicals posing severe health risks. Therefore, removal of Hg 0 from the environment is imperative. Our study introduces [Mo 3 S(S 2 ) 6 ] 2− � [Mo 3 S 13 ] 2− -functionalized layered double hydroxide nanoparticles, (LDH−Mo 3 S 13 ), as an excellent sorbent for gaseous Hg 0 . This material achieved a remarkable sorption capacity of ∼2.33 × 10 3 mg/g for gaseous elemental Hg 0 . Such an enormously high sorption capacity makes this material the lead non-platinum-based Hg 0 gas sorbent known to date. Although sulfides of the Mo 3 S(S 2 ) 6 species of LDH predominantly serve as active sites for capturing gaseous Hg, their integration is essential for the accessibility of gaseous Hg 0 to the individual reactive active site between the LDH lamella. A heterogeneous reaction between the Hg 0 vapor and the solid LDH−Mo 3 S 13 sorbent enables the oxidation of gaseous Hg 0 to Hg 2+ , and the reduction of the S 2 2− groups to 2S 2− yields redox-driven formation of the nanocrystalline HgS onto the solid sorbents. Density functional theory (DFT) calculations provide further insights into the interactions between Hg 0 and S, indicating adsorption energy ranging from −8 to −19 kJ/mol. Moreover, the overall reaction enthalpy was calculated as −4048 kJ/mol, suggesting the spontaneous formation of HgS. This investigation unveils an atomistic understanding of the redoxdriven interactions between Hg 0 vapor and Mo 3 S(S 2 ) 6 species as well as the remarkably high mercury sorption capacity of LDH− Mo 3 S 13 , highlighting the potential of metal sulfide-functionalized LDHs for the efficient immobilization of gaseous elemental mercury.

In nine children epileptic seizures were treated with Diazepam given intrarectally. A total of forty one epileptic crisis occurred in these children and were evaluated for this study. In all patients seizures were controlled in a mean time of 3.2 minutes considering the best response and 3.9 minutes averaging all forty one treatments; seizures treated five minutes or earlier after their start were controlled faster than those treated later. Immediately recurrent seizures were seen only in 2.5% of all seizure crisis treated this way, that is a low recurrence rate for this type of patients. No undesired effects of Diazepam were seen even though three patients were simultaneously receiving maintenance doses of phenobaibital. Intrarectal administration of Diazepam is a good and harmless alternative to the intravenous route with low immediate seizure recurrence rate, in the emergency treatment of seizure spells. Las convulsiones son el problema mas frecuente de la neurologia pediatrica de urgencia, ya que 7 a 8% de los nifios menores de 5 afios de edad presentan por lo menos uno de tales episodios en su vida 1 . La necesidad de detener prontamente la crisis y evitar que se repita es una tarea que ha sido desde 1963 facilitada con la introduccion del Diazepam endovenoso. 2 Por diversas razones, no siempre es facil llegar con el farmaco a la vena en forma oportuna y desde trabajos hechos en 1972 3 y 1973 4 , la via rectal ha sido utilizada como eficaz alternativa de la venosa 5 , por cuanto las concentraciones sangui'neas obtenidas por ambas vi'as son comparables, terapeuticamente, en ninos 6 -7 y adultos 8 . No tenemos informacion en nuestro medio que diazepam sea sistematicamente usado por via rectal 9 .El objetivo de esta investigacion es comunicar la experiencia de los autores sobre el uso de diazepam en solucion por via rectal en el tratamiento de urgencia de ninos con crisis epilepticas. PACIENTES Y METODOLa muestra esta compuesta por nueve nifios de 3 meses a 14 afios de edad, cuyas caiacten'sticas clinicas se detallan en la Tabla 1; 2 enfermos eran portadores de epilepsia y genopati'a, 3 pacientes sufrian dano organico cerebral y epilepsia, un nino teni'a un smdrome hipotonico y epilepsia, uno meningitis purulenta, otro convulsiones febrites y del ultimo no se tiene informacion puesto que no volvio a consultar. Cuatro enfermos recibian anticonvulsionantes en el momenta del estudio, 3 en tratamiento continuado con fenobarbital teni'an concentraciones plasmaticas en rango terapeutico. Cuatro pacientes teni'an alteraciones especificas para epilepsia en susregistros clectroencefalograficos.Los tipos de crisis epilepticas por los cuales recibieron tratamiento de urgencia se especifican en la Tabla 2, donde se destaca que todos presentaron crisis generalizadas y uno focal.Se efectuaron 41 tratamientos, de los cuales 24 se practicaron en 2 ninos portadores de epilepsias resistentes y mixtas, mediante diazepam (Valium® Roche) en solucion no dilui'da, la misma utilizada para la inyeccion por via endovenosa, en una jerin...
