Nuclear Alterations

Apoptosis is triggered by the activation of caspases and characterized by chromatin condensation and nuclear fragmentation (type II nuclear morphology). Necrosis is depicted by a gain in cell volume (oncosis), swelling of organelles, plasma membrane leakage, and subsequent loss of intracellular contents. Although considered as different cell death entities, there is an overlap between apoptosis and necrosis. In this sense, mounting evidence suggests that both processes can be morphological expressions of a common biochemical network known as “apoptosis-necrosis continuum.” To gain insight into the events driving the apoptosis-necrosis continuum, apoptotically proficient cells were screened facing several apoptotic inducers for the absence of type II apoptotic nuclear morphologies. Chelerythrine was selected for further studies based on its cytotoxicity and the lack of apoptotic nuclear alterations. Chelerythrine triggered an early plasma membrane leakage without condensed chromatin aggregates. Ultrastructural analysis revealed that chelerythrine-mediated cytotoxicity was compatible with a necrotic-like type of cell death. Biochemically, chelerythrine induced the activation of caspases. Moreover, the inhibition of caspases prevented chelerythrine-triggered necrotic-like cell death. Compared with staurosporine, chelerythrine induced stronger caspase activation detectable at earlier times. After using a battery of chemicals, we found that high concentrations of thiolic antioxidants fully prevented chelerythrine-driven caspase activation and necrotic-like cell death. Lower amounts of thiolic antioxidants partially prevented chelerythrine-mediated cytotoxicity and allowed cells to display type II apoptotic nuclear morphology correlating with a delay in caspase-3 activation. Altogether, these data support that an early and pronounced activation of caspases can drive cells to undergo a form of necrotic-like regulated cell death.

Cylindrical Holes

A wide-acceptance-angle spherical grid composed of numerous micro cylindrical holes was developed to be used for the retarding grid of a display-type retarding field analyzer (RFA) and to enhance the energy resolution (E/ΔE). Each cylindrical hole with a diameter of 50 µm and a depth of 80 µm is directed to the spherical center. The inner radius of the spherical grid is 40 mm. The holed area corresponds to an acceptance angle of ±52°. The E/ΔE of an RFA equipped with the developed holed grid was estimated to be 2000 from a measured Au 4f photoemission spectrum. A clear photoelectron hologram was observed in the Mo 4p core-level region of MoS2, indicating that the RFA with the holed grid is effective for photoelectron holography.

ABSTRACT Objective: To investigate the accuracy of panoramic radiography (PR) in diagnosing maxillary sinus-root relationships (SRRs). Materials and Methods: PubMed, EMBASE, CENTRAL, Web of Science, ScienceDirect, CBM, Baidu Scholar, and SIGLE were searched. The studies comparing the diagnostic accuracy of PR and computed tomography/cone-beam computed tomography (CT/CBCT) for SRR were included. Results: Eleven studies were included. Meta-analyses showed that, for type I SRR, PR had the highest specificity, positive likelihood ratio (+LR), diagnostic odds ratio (DOR), and area under the curve (AUC), with a high sensitivity and a low negative LR (−LR). For type IV, PR had a high DOR and AUC, with the highest sensitivity but a low +LR, the lowest –LR, and the lowest specificity. For type II, PR had the lowest AUC, with a low sensitivity, +LR, and DOR and a high −LR. For type III, PR had the lowest sensitivity, +LR, and DOR and the highest −LR. The distance from root tips to the maxillary sinus floor on PR was significantly longer (mean difference: −1.88 mm; 95% confidence interval: −2.19 to −1.57; P < .0001) than that on CT/CBCT. Conclusions: Currently available evidence suggests PR could be reliable for detecting type I SRR. PR has a good ability to confirm true type IV SRR but a poor ability to rule out false type IV SRR. For type II and III SRR, PR shows poor accuracy and tends to overestimate the extent of protrusion of the roots into the maxillary sinus. When PRs display type II, III, or IV SRR and related treatment is needed, CBCT should be used for further examinations.

The principle advantage of a head-up display (HUD) is that a driver does not have to take their eyes off the road. However, the advantage afforded by a HUD may be lost when surprising or unexpected events occur in the traffic environment. This study sought to determine the time-costs for elderly drivers associated with responses to the appearance of a pedestrian (critical event) while engaged in a HUD task. Sixteen older drivers (65 to 81, Mean = 73) interacted with a number of tasks presented in a low-cost driving simulator. Critical event onset after engaging in a HUD task (+100, +250, +1000 ms), display location (head-up, head-down), tracking difficulty (easy, hard), and display type (visual search, verbal memory) were the within-subjects variables. Analyses of perception-response time (PRT) and missed events (error) indicate that braking to a critical event, while performing a display task, is affected by the interaction between the temporal and spatial limitations of visual attention. HUD design and safety issues are briefly considered.
