Antibacterial effects of extracts of Ocimum gratissimum and piper guineense on Escherichia coli and Staphylococcus aureus
The upsurge in the prevalence of side effects of many synthetic antimicrobial agents and incidence of multidrug resistant bacteria has spurred scientists on the research for plant based antimicrobial of therapeutic potentials. Ocimum gratissimum and Piper guineense present such potential of high medicinal value. These plants are used in Nigeria traditionally as condiments and for treatment of
various ailments such as pyorrhea, dysentery and bronchitis. Aqueous and ethanol extracts of O. gratissimum and P. guineense leaves were screened for antibacterial activity against Escherichia coli and Staphylococcus aureus. Both extracts were found to exhibit selective inhibition against the isolates. The diameter zones of inhibition exhibited by the extracts were between 2 + 0.01 – 10 + 0.10 mm. The minimum inhibitory concentration (MIC) determined by the agar diffusion method was between 10.00 and 2.50 mg/ml-1. Ethanol extracts showed more inhibitory effect compared to the aqueous extracts. Results obtained show that the extracts of O. gratissimum and P. guineense possess some
level of antibacterial activities against E. coli and S. aureus
Association of long QT syndrome loci and cardiac events among patients treated with beta-blockers
none10Long QT Syndrome (LQTS) is a genetic disease characterized by prolonged ventricular repolarization,
syncope, ventricular arrhythmias, and sudden death,1-3 often precipitated by emotion or exercise. Primarily
according to nonrandomized trial evidence, beta-blockers are considered first line prophylactic therapy,4 whereas patients
refractory to _-blockers may be treated with left-sided cardiac sympathetic denervation, pacemakers, or implantable
cardioverter defibrillators.1,5-8 The hypothesis that the efficacy of therapy may vary according to the genetic
form of the disease has been proposed7 but not thoroughly investigated.
Three genetic loci account for nearly 98% of genetically characterized patients. In this investigation, we sought
to describe and assess outcomes of beta-blocker–treated patients affected by the 3 most common genetic loci of
LQTS9: LQT1, LQT2, and LQT3, caused by genetic defects on KCNQ1, KCNH2 and SCN5A genes.Tematica Ex SIR: Strategie innovative per la diagnosi ed il trattamento di patologie ad elevato rischio cardiovascolare (Classif.

Live Attitude
This thesis serves as an open-ended document of a young artist attempting to sift through his accumulated opinions in order to figure out what it means to accept complicity in the face of auspicious authority, rapid turnover, and paper-thin irony and nihilism, while still striving to stake a claim at something worth making and defending
Structure refinement of amorphous Cd-As by analysis of partial radial distribution functions
The anomalous wide angle X-ray scattering technique was used to determine
the partial structure factors and then the partial radial distribution
functions for vacuum evaporated Cd—As amorphous films containing 41 and
74% at. As. The experiments were performed using synchrotron radiation
tuned near the As and Cd absorption edges. The obtained structural information
about the individual Cd—Cd, Cd—As and As—As correlations shows
that As and Cd remain almost tetrahedrally coordinated and suggest a certain
degree of chemical disorder of the investigated samples
Synthesis and Reactivity of Tricarbonyl(1-ethoxy-carbonyl-2-methylpentadienyl)iron(1+) Cation
The title cation was prepared in two steps from the known (ethyl 3-methyl-6-oxo-2,4-hexadienoate)Fe(CO)3. Reation of the cation with NaBH3CN, methyl cuprate, phthalimide, water, PPh3, or malonate anions gave predominantly the products from nucleophilic attack at the C5 pentadienyl carbon

Divergencia del régimen tributario aplicable a los clubes profesionales en Colombia
ArtÃculo de investigaciónEn el presente artÃculo el lector encontrará un breve estudio acerca del régimen jurÃdico tributario aplicable a los clubes deportivos profesionales en Colombia destacando las divergencias de disposiciones normativas a las que están sometidos los mismos, toda vez que, le es permitido estructurarse bajo la forma de una asociación civil o de una sociedad anónima, lo cual opera en perjuicio de la competencia, pues la diversa carga tributaria a la que se ven sometidos genera inequidad en las cargas operativas de los clubes competidores. Todo lo anterior se analizará crÃticamente a partir del mandato constitucional de fomento del deporte que se ha establecido a cargo del Estado.PregradoAbogad
The limits of concept. The part of Michel Claura’s writings in the reception of Daniel Buren and Niele Toroni’s works in Belgium
Poniendo en relación los escritos de Michel Claura, que buscaron definir la noción de arte conceptual a fines de los años sesenta, y las obras realizadas en Bélgica en el mismo perÃodo, se mostrará cómo esta definición fue difundida en ese paÃs y qué consecuencias tuvo sobre la producción artÃstica belga. Publicados en las revistas Les Lettres Françaises y Opus International, esos textos tuvieron una gran difusión en Bélgica a través de las galerÃas MTL y Wide White Space y produjeron importantes debates sobre el problema del autor, para René Denizot, determinaba el "lÃmite del concepto". Es en esa falla que van a caer ciertos artistas belgas al buscar demostrar en la práctica esos lÃmites y, en cierta medida, intentar franquearlos
