Ring Currents and the PCP Rule [PDF]
Croatica Chemica Acta, 2010 According to the recently discovered PCP rule, the intensity of cyclic conjugation in the fivemembered rings of polycyclic conjugated hydrocarbons related to acenaphthylene and fluoranthene increases with the number of phenyl-cyclopentadienyl (PCP) fragments present in the molecule.

Effect of a ring on the cyclic conjugation in another ring: applications to acenaphthylene-type polycyclic conjugated molecules [PDF]
Journal of the Serbian Chemical Society, 2010 In a recent work, a method was developed for assessing the influence ief(G, Z0|Z1) of a ring Z1 on the energy effect of another ring Z0 in a polycyclic conjugated molecule G. Herein, a report is given of detailed numerical investigations of ief(G, Z0|Z1)

Diagnostic performance of the (1-3)-β-D-glucan assay in patients with Pneumocystis jirovecii compared with those with candidiasis, aspergillosis, mucormycosis, and tuberculosis, and healthy volunteers. [PDF]
PLoS ONE, 2017 BACKGROUND:Diagnosis of pneumocystis pneumonia (PCP) relies on microscopic visualization of P. jirovecii, or detection of Pneumocystis DNA in respiratory specimens, which involves invasive procedures such as bronchoalveolar lavage.
