Subarachnoid Space Opacification on Delayed Postcontrast Fluid-Attenuated Inversion Recovery Imaging in Spontaneous Intracranial Hypotension: Visualizing the Monro-Kellie Hypothesis Intracranial volume compensatory changes explained by the MonroKellie hypothesis (MKH) occur in spontaneous intracranial hypotension (SIH) and may be seen on MR imaging. This case illustrates previously unreported f...

Abstract AHPCS is a pre-ceramic polymer utilised as precursor to SiC. An initial polymerisation cross-linked network followed by complex sequence of processes ultimately leading amorphous Using thermal volatilisation analysis (TVA) accompanied with solid-state NMR (SSNMR), FTIR, MS, DSC and TGA the complete profile was identified. Between 160 – 300 °C, cross-links through allyl group undergoes ...

Resumo Este estudo investigou a subnotificação de óbitos por Síndrome da Imunodeficiência Adquirida (AIDS) no Brasil, utilizando o produto do pareamento entre Sistema Informação sobre Mortalidade (SIM) e Hospitalar (SIH) para os anos 2008 2012. A hipótese era que houvesse registrados SIM deveriam ter AIDS como causa básica morte, mas tinham causas mal classificadas. Muitos desses falecidos tive...

Time-resolved kinetic studies of the reactions of silylene, SiH(2), and dideutero-silylene, SiD(2), generated by laser flash photolysis of phenylsilane and phenylsilane-d(3), respectively, have been carried out to obtain rate coefficients for their bimolecular reactions with 2-butyne, CH(3)C[triple bond, length as m-dash]CCH(3). The reactions were studied in the gas phase over the pressure rang...

Recent research has highlighted the relevance of intellectual humility to politics. Among a U.S. sample (N = 852), we examined self-reported sociopolitical (SIH), nonthreatening awareness fallibility one’s views about topics central society and SIH was associated with being less likely dislike/avoid political discussion, more tolerance, social domina...

Several cases of cerebral venous thrombosis (CVT) due to spontaneous intracranial hypotension (SIH) have been reported, with an estimated occurrence rate 1–2% among patients decreased pressure. However, the causal relationship between SIH and CVT as a potential risk factor is not well understood. According Monro-Kellie principle, this thought be caused by compensatory expansion system, damage i...

An efficient and high-yielding "hydrogen-free" reduction of α,β-unsaturated alkenes was carried out employing Grubbs' catalyst in a non-metathetic role and Et(3)SiH. Conditions were optimized under microwave irradiation. Application to the solid-phase organic synthesis allows a facile construction of sp(3)-sp(3) carbon bonds through a sequential cross metathesis/olefin reduction.
