RESUMO

The novel mono-silyl [(R3Si)AlX2]2, di-silyl [(R3Si)2AlX]2, tri-silyl (R3Si)3Al·Et2O, and -ate-complex [(R3Si)4Al]-·Li+(Et2O)2 have been synthesized by reaction of AlX3 (X = Cl, Br) with silyl lithium reagents (tBuMe2SiLi, Et3SiLi) in Et2O. Treatment of these compounds with Me3N yields the corresponding amine-coordinated silyl aluminum complexes (R3Si)AlX2·NMe3, (R3Si)2AlX·NMe3, and (R3Si)3Al·NMe3. An intramolecular amine-coordinated mono-silyl aluminum complex Me2N(CH2)3(tBuMe2Si)2SiAlCl2 was prepared by the reaction of Me2N(CH2)3(tBuMe2Si)2SiLi with AlCl3 in Et2O. In addition, reaction of [(tBuMe2Si)2AlBr]2 with LiAlH4 yields the novel aluminum hydride cluster [(tBuMe2Si)2Al(µ-H)AlH3]6 which upon addition of TMEDA yields the ion pair [((tBuMe2Si)2AlH)2(µ-H)]-[AlH2(TMEDA)2]+. The amine-coordinated di- and tri-silyl aluminum complexes possess higher thermal stability than the analogous etherate complexes and are reasonably volatile (100-140 °C, 0.2 Torr). The materials presented herein were analyzed via thermal gravimetric analysis (TGA) and differential scanning calorimetry (DSC) to assess their viability as potential ALD precursors.

RESUMO

Tenofovir (TDF) is an inhibitor of reverse transcriptase nucleotide analogue, although it has good tolerability and high anti-retroviral activity, its effect on the kidney has been a concern. OBJECTIVE: To describe a girl infected with HIV who presented Fanconi syndrome during antiretroviral therapy with TDF. CLINICAL CASE: We describe a HIV-1-infected girl, who after 18 months treatment with TDF presented loss of strength and pain of the lower extremities with functional impairment. Laboratory findings were consistent with Fanconi syndrome. Radiographs showed bilateral hip fracture and wrists. Full recovery of Fanconi syndrome was achieved four months after changing antiretroviral therapy. CONCLUSIONS: TDF-prescribing physicians must be prepared to detect signs and symptoms of renal dysfunction and immediately consider switching to another antiviral drug.

RESUMO

El tenofovir (TDF) es un inhibidor de la transcriptasa reversa análogo de nucleótidos, aunque tiene buena tolerabilidad y alta actividad antirretroviral, su efecto sobre el riñón ha sido un motivo de preocupación. Objetivo: Describir el caso de una niña infectada por VIH que presenta síntomas y hallazgos de laboratorio compatibles con un síndrome de Fanconi durante el tratamiento con TDF como parte de su terapia antirretroviral. Caso clínico: Niña infectada por el VIH-1, que después de 18 meses con el tratamiento con TDF presentó pérdida de fuerza y dolor de las extremidades inferiores con deterioro funcional. Los hallazgos de laboratorio fueron compatibles con el síndrome de Fanconi. Las radiografías mostraron fractura bilateral de cadera y muñecas. El síndrome de Fanconi se recuperó por completo cuatro meses después del cambio de terapia antirretroviral. Conclusiones: Los médicos que prescriben TDF deben estar preparados para detectar signos y síntomas indicativos de disfunción renal y considerar de inmediato el cambio del fármaco a otro antirretroviral.

RESUMO

The addition of the reducing agent tris(2-carboxyethyl) phosphine (TCEP) during the formation of α,ω-alkanedithiols monolayers on Au(111) using the immersion method produces the assembly of monolayers with bicoordinated molecules (both S-terminal groups bound to the surface) that have a reductive desorption potential that is more positive than for monolayers with monocoordinated molecules in a standing up configuration. We show that the use of TCEP either during formation of the monolayer or as a post treatment procedure allows the controlled formation of monolayers with bicoordinated or monocoordinated configurations. Density functional theory (DFT) calculations were performed to elucidate the role of TCEP in the formation of the bicoordinated configuration. We investigated the TCEP-dithiol interaction in ethanol solvent as well as the coadsorption of trimethylphosphine with 1,2-ethanedithiol on Au(111). The Brønsted base character of the phosphine facilitates the H exchange from the -SH groups of the dithiol to the phosphorus atom of TCEP with very low activation energy barriers, thus allowing the thiolate groups to bind to the Au(111) surface, thus yielding the bicoordinated configuration. Dithiol lifting mechanisms such as H exchange between S atoms and the formation of intra/inter layer disulfide bonds have much higher energy barriers.

RESUMO

The synthesis of copper and silver silyl complexes containing either N-heterocyclic carbenes or nitrogen donors is described. Alterations made to both the neutral donor ligands as well as the silyl group provided access to a number of different compounds. Many of the complexes synthesized were studied in the solid state and the effect of the donor ligand on the final structure of the complexes was examined. The thermal properties of the complexes were explored using thermogravimetric analysis, differential scanning calorimetry and sublimations. Some of the complexes synthesized were demonstrated to be promising volatile metal precursors.

RESUMO

Initiation processes in a family of ruthenium phosphonium alkylidene catalysts, some of which are commercially available, are presented. Seven 16-electron zwitterionic catalyst precursors of general formula (H(2)IMes)(Cl)(3)Ru=C(H)P(R(1))(2)R(2) (R(1) = R(2) = C(6)H(11), C(5)H(9), i-C(3)H(7), 1-Cy(3)-Cl, 1-Cyp(3)-Cl, 1-(i)Pr(3)-Cl; R(1) = C(6)H(11), R(2) = CH(2)CH(3), 1-EtCy(2)-Cl; R(1) = C(6)H(11), R(2) = CH(3), 1-MeCy(2)-Cl; R(1) = i-C(3)H(7), R(2) = CH(2)CH(3), 1-Et(i)Pr(2)-Cl; R(1) = i-C(3)H(7), R(2) = CH(3), 1-Me(i)Pr(2)-Cl) were prepared. These compounds can be converted to the metathesis active 14-electron phosphonium alkylidenes by chloride abstraction with B(C(6)F(5))(3). The examples with symmetrically substituted phosphonium groups exist as monomers in solution and are rapid initiators of olefin metathesis reactions. The unsymmetrically substituted phosphonium alkylidenes are observed to undergo reversible dimerization, the extent of which is dependent on the steric bulk of the phosphonium group. Kinetic and thermodynamic parameters of these equilibria are presented, as well as experiments that show that metathesis is only initiated through the monomers; thus dedimerization is required for initiation. In another detailed study, the series of catalysts 1-R(3) were reacted with o-isopropoxystyrene under pseudo-first-order conditions to quantify second-order olefin binding rates. A more complex initiation process was observed in that the rates were accelerated by catalytic amounts of ethylene produced in the reaction with o-isopropoxystyrene. The ability of the catalyst to generate ethylene is related to the nature of the phosphonium group, and initiation rates can be dramatically increased by the intentional addition of a catalytic amount of ethylene.

RESUMO

Fetal bovine serum (FBS) is an important factor in the culture of Trypanosoma cruzi, since this parasite obtains and metabolizes fatty acids (FAs) from the culture medium, and changes in FBS concentration reduce the degree of unsaturation of FAs in phosphoinositides. When T. cruzi epimastigotes were cultured with 5% instead of 10% FBS, and stearic acid was used as the substrate, (9) desaturase activity decreased by 50%. Apparent K (m) and V (m) values for stearic acid, determined from Lineaweaver-Burk plots, were 2 microM and 219 pmol/min/mg of protein, respectively. In studies of the requirement for reduced pyridine nucleotide, (9) desaturase activity reached a maximum with 8 microM NADH and then remained constant; the apparent K (m) and V (m) were 4.3 microM and 46.8 pmol/min/mg of protein, respectively. The effect of FBS was observed only for (9) desaturase activity; (12) desaturase activity was not affected. The results suggest that decreased FBS in culture medium is a signal that modulates (9) desaturase activity in T. cruzi epimastigotes.

RESUMO

The reaction of phosphonium alkylidenes [(H2IMes)RuCl2=CHPR3]+[A]- (R = C6H11, A = OTf or B(C6F5)4, 1-Cy; R = i-C3H7, A = ClB(C6F5)3 or OTf, 1-iPr) with 1 equiv of ethylene at -78 degrees C, in the presence of 2-3 equiv of a trapping olefin substrate, yields intermediates relevant to olefin metathesis catalytic cycles. Dimethyl cyclopent-3-ene-1,1-dicarboxylate gives solutions of a substituted ruthenacyclobutane 3 of relevance to ring closing metathesis catalysis. 1H and 13C NMR data are fully consistent with its assignment as a ruthenacyclobutane, but 1JCC values of 23 Hz for the CalphaH2-Cbeta bond and 8.5 Hz for the CalphaH-Cbeta bond point to an unsymmetrical structure in which the latter bond is more activated than the former. In contrast, trapping with acenaphthylene leads to an olefin carbene complex (6) in which the putative ruthenacyclobutane has opened; this species was also fully characterized by NMR spectroscopy and compared to related species reported previously.

RESUMO

The phosphonium alkylidene [(NHC)Cl2Ru=CH(PCy3)]+[B(C6F5)4]-, 1, (NHC = N-heterocyclic carbene, Cy = cyclohexyl, C6H11) reacts with 2.2 equiv of ethylene at -50 degrees C to form the 14-electron ruthenacyclobutane (NHC)Cl2Ru(CH2CH2CH2), 2. NMR spectroscopic data indicates that 2 has a C2v symmetric structure with a flat, kite shaped ruthenacyclobutane ring with significant Calpha-Cbeta agostic interactions with the Ru center. Intramolecular exchange of Calpha and Cbeta is fast (14(2) s-1 at 223 K) as measured by EXSY spectroscopy. Intermolecular exchange of Calpha and Cbeta with the methylene groups of free ethylene is much slower and first order in both [Ru] and [H2C=CH2] (4.8(3) x 10-4 M-1 s-1). Activation parameters for this process are DeltaH++ = 13.2(5) kcal mol-1 and DeltaS++ = -15(2) cal mol-1 K-1, also consistent with a rate limiting associative substitution as the key step in this exchange process. On the basis of this observation, mechanisms for the intermolecular exchange process are proposed and the implications for the mechanism of the propagation steps in catalytic olefin metathesis as mediated by Grubbs catalysts are discussed.

RESUMO

The 14-electron ruthenium phosphonium alkylidene complex [(IH2Mes)Cl2Ru=CH(PCy3)][B(C6F5)4], 1b, a highly active olefin metathesis catalyst, reacts with stoichiometric quantities of ethylene at -50 degrees C in CD2Cl2 to generate the ruthenacyclobutane complex [(IH2Mes)Cl2RuCH2CH2CH2], 2, and [CH2=CH(PCy3)][B(C6F5)4] in quantitative yield by NMR spectroscopy. 1H and 13C NMR spectroscopies on 2 and 2-13C3 are consistent with a symmetrical C2v structure, providing the first experimental information concerning this crucial intermediate in ruthenium-mediated olefin metathesis. At -50 degrees C, exchange with free ethylene takes place on the chemical time scale. Complex 2 decomposes in solution upon warming to room temperature, generating propene and unknown ruthenium product(s).

RESUMO

No es suficiente que la atención del menor esté a cargo de aquéllos que sólo forman parte del equipo médico pediátrico tradicional, sino que es preciso integrar un programa de ayuda psicológica, que sustente dicha labor; sumándose así, las acciones de los profesionales de salud mental, tales como psiquiatras, psicólogos y terapeutas ocupacionales. El trabajo conjunto del área médica y psiquiátrica redundará en mejores relaciones interpersonales, asesoramiento, apoyo e intervención, que aminoren el impacto sobre el niño, la familia, y el grupo terapéutico.

RESUMO

Este documento tiene por objeto entregar una información que pemita asegurar que los traslados de pacientes críticos siguen los principios más eficientes y seguros para estos casos: organización, personal educado, enfoque sistemático, equipo mínimo, seguridad, eficiencia y ética. La racionalización de los cuidados del paciente crítico ha determinado una mejor evaluación, estabilización y terapia del niño grave, lactante o recién nacido. Las normas de programas como Advanced Trauma Life Support han contribuido también al mejoramiento de la atención del paciente grave. Normas generales como las de la Academia de Pediatría de los EE.UU han ayudado también en la misma dirección. Un aspecto que aún debe mejorar y que es fundamental en este país de larga y escarpada geografía, es el traslado de los pacientes graves. De hecho se ha podido observar que este se hace, casi siempre, por personal inexperimentado, con muy malos recursos y sin las medidas de seguridad necesarias. Lo usual en este momento en Chile es que el recién nacido, lactante o niño más grave de un hospital sea trasladado en una ambulancia bajo la responsabilidad de un auxiliar de enfermería que no ha sido entrenada para las emergencias mayores que se puedan presentar durante el viaje. La experiencia con equipos mejor entrenados, como el de Coyhaique y esfuerzos aislados ocasionales, es aún demasiado limitada para poder generalizar. Un trabajo nuevo, en el área del trabajo paramédico de rescate pediátrico es el que se ha iniciado en enero de 1993 en el Hospital Roberto del Río (Santiago)

RESUMO

Se analiza una serie de 45 niños de 2 a 15 años, promedio 7,7 años con cuadro clínico e histológico de GNA, que fueron seguidos hasta por treinta meses. Se realizó en ellos dos estudios histológicos (ML, ME, IN) en biopsias practicadas al comienzo de la enfermedad (promedio 20 días) y la segunda a los 194 ó 590 días en promedio. En el estudio clínico se destaca la normalización del edema a los 8,8 días y la hipertensión a los 4,3 días. Sólo se obtuvo estreptococo betahemolítico en cuatro enfermos, lo que puede relacionarse con el tratamiento antibiótico recibido previamente por estos niños. En el examen de orina un alto porcentaje no presentó hematuria (44%) o proteinuria (49%) en el examen de ingreso y sólo 29,9% tuvo cilindruria. La albuminemia tuvo valores bajo lo normal en el 35,6% de los niños, alfa 2 globulina y gamaglobulina con valores normales en todos. El complemento C3 fue en promedio 41,3m% y sólo 3 enfermos tenían valores sobre 100mg%. Se describen las curvas de antiestreptolisina O (ASO) y STZ en estos niños y se destaca la necesidad de determinaciones seriadas tanto de C3 como ASO y STZ. En el análisis de 194 contactos se obtuvo sólo 5 frotis faríngeos y 10 cutáneos positivos a estreptococo betahemolítico e estafilococo. En el estudio histológico se encontró buena correlación entre la intensidad de las lesiones en microscopía de luz (ML) y microscopía electrónica (ME). En esta última se destaca en la primera biopsia que todos tenían depósitos inmunes intramembranosos segmentarios y 84% con depósitos en joroba. La segunda biopsia mostró una disminución apreciable de la intensidad de las lesiones a los 6 meses y en las realizadas en promedio a los 590 días se encontró ya tres casos que pueden considerarse normales desde el punto de vista histológico. Otros tres con lesiones...

RESUMO

Se estudiaron 40 pacientes, de los cuales 20 fueron tratados con la combinación Trimetoprim-Sulffametopirazina (TMP-SMP) y los 20 restantes con Nitrofurantina (NF). En ambos grupos los pacientes se eligieron al azar y tenían antibiogramas sensibles a los medicamentos en estudio. La duración del tratamiento fue de 10 días y el período de observación de 30 días. La edad fluctuó entre los 5 meses y los 14 años, predominando el sexo feminino. Los síntomas más frecuentes fueron disuria, polaquiuria (90% TMP-SMP y 85%NF) y fiebre (40% TMP-SMP y 30% NF). El estudio bacteriológico inicial demostró en los dos grupos predominio de E. coli (80% TMP-SMP y 90% NF). Dentro de las 72 horas los urocultivos ya eran negativos en el 100% de los pacientes tratados con ambos esquemas de tratamiento los que se mantuvieron estériles en el cultivo de los 30 días. Clínicamente en el grupo tratado con TMP-SMP el 89.4% era asintomático respecto al 85% del grupo tratado con el fármaco de control. Un solo paciente tratado con Nitrofurantoina resultó sintomático al final del tratamiento, pero al finalizar el período de control todos los pacientes de ambos grupos pudieron considerar-se curados clínicamente y con urocultivos estériles no habiéndose verificado recaídas. La eficacia del tratamiento no resulta significativamente diferente entre los dos fármacos. La tolerancia ha sido buena para ambos tratamientos. Un sólo paciente del grupo tratado con Nitrofurantoína acusó un episodio transitorio de náusea y vómito
