Quantum Calculations of Electron Tunneling in Respiratory Complex III
The most detailed and comprehensive
to date study of electron transfer
reactions in the respiratory complex III of aerobic cells, also known
as <i>bc</i><sub>1</sub> complex, is reported. In the framework
of the tunneling current theory, electron tunneling rates and atomistic
tunneling pathways between different redox centers were investigated
for all electron transfer reactions comprising different stages of
the proton-motive Q-cycle. The calculations reveal that complex III
is a smart nanomachine, which under certain conditions undergoes conformational
changes gating electron transfer, or channeling electrons to specific
pathways. One-electron tunneling approximation was adopted in the
tunneling calculations, which were performed using hybrid Broken-Symmetry
(BS) unrestricted DFT/ZINDO levels of theory. The tunneling orbitals
were determined using an exact biorthogonalization scheme that uniquely
separates pairs of tunneling orbitals with small overlaps out of the
remaining Franck–Condon orbitals with significant overlap.
Electron transfer rates in different redox pairs show exponential
distance dependence, in agreement with the reported experimental data;
some reactions involve coupled proton transfer. Proper treatment of
a concerted two-electron bifurcated tunneling reaction at the Q<sub>o</sub> site is given

Assessment of Still and Moving Images in the Diagnosis of Gastric Lesions Using Magnifying Narrow-Band Imaging in a Prospective Multicenter Trial
<div><p>Objectives</p><p>Magnifying narrow-band imaging (M-NBI) is more accurate than white-light imaging for diagnosing small gastric cancers. However, it is uncertain whether moving M-NBI images have additional effects in the diagnosis of gastric cancers compared with still images.</p><p>Design</p><p>A prospective multicenter cohort study.</p><p>Methods</p><p>To identify the additional benefits of moving M-NBI images by comparing the diagnostic accuracy of still images only with that of both still and moving images. Still and moving M-NBI images of 40 gastric lesions were obtained by an expert endoscopist prior to this prospective multicenter cohort study. Thirty-four endoscopists from ten different Japanese institutions participated in the prospective multicenter cohort study. Each study participant was first tested using only still M-NBI images (still image test), then tested 1 month later using both still and moving M-NBI images (moving image test). The main outcome was a difference in the diagnostic accuracy of cancerous versus noncancerous lesions between the still image test and the moving image test.</p><p>Results</p><p>Thirty-four endoscopists were analysed. There were no significant difference of cancerous versus noncancerous lesions between still and moving image tests in the diagnostic accuracy (59.9% versus 61.5%), sensitivity (53.4% versus 55.9%), and specificity (67.0% versus 67.6%). And there were no significant difference in the diagnostic accuracy between still and moving image tests of demarcation line (65.4% versus 65.5%), microvascular pattern (56.7% versus 56.9%), and microsurface pattern (48.1% versus 50.9%). Diagnostic accuracy showed no significant difference between the still and moving image tests in the subgroups of endoscopic findings of the lesions.</p><p>Conclusions</p><p>The addition of moving M-NBI images to still M-NBI images does not improve the diagnostic accuracy for gastric lesions. It is reasonable to concentrate on taking sharp still M-NBI images during endoscopic observation and use them for diagnosis.</p><p>Trial registration</p><p>Umin.ac.jp <a href="https://upload.umin.ac.jp/cgi-open-bin/ctr/ctr.cgi?function=brows&action=brows&type=summary&recptno=R000009477&language=E" target="_blank">UMIN-CTR000008048</a></p></div
