Widefield light sheet microscopy using an Airy beam combined with deep-learning super-resolution

Imaging across length scales and in depth has been an important pursuit of widefield optical imaging. This promises to reveal fine cellular detail within a widefield snapshot of a tissue sample. Current advances often sacrifice resolution through selective sub-sampling to provide a wide field of view in a reasonable time scale. We demonstrate a new avenue for recovering high-resolution images from sub-sampled data in light sheet microscopy using deep-learning super-resolution. We combine this with the use of a widefield Airy beam to achieve high-resolution imaging over extended fields of view and depths. We characterise our method on fluorescent beads as test targets. We then demonstrate improvements in imaging amyloid plaques in a cleared brain from a mouse model of Alzheimer’s disease, and in excised healthy and cancerous colon and breast tissues. This development can be widely applied in all forms of light sheet microscopy to provide a two-fold increase in the dynamic range of the imaged length scale. It has the potential to provide further insight into neuroscience, developmental biology, and histopathology

Prerequisite of a Holistic Blend of Traditional and Modern Approaches of Cancer Management

Background: With the advent of changes in lifestyle of people all around the world, cancer cases have been showing an exponential rise. Researchers from varied fields have been trying to solve this tricky issue. Methods: We undertook a systematic search of bibliographic databases of peer-reviewed research literature to evaluate the holistic blend of modern and traditional approaches, especially the Ayurvedic perspective of treatment of cancer along with the effect of our diet and lifestyle on the management (both prevention and cure) of cancer. Results: On the basis of extensive literature survey, it was found that Ayurveda as one of the ancient medicinal systems had been very well documented for utilizing its best practices for the treatment of various diseases including cancer, by utilization of several herbal plants and dietary interventions as therapeutics. Active components present in various herbs, which interfere with certain molecular targets to inhibit carcinogenesis are also summarized. Further, beneficial effects of yoga and exercise on psychological distress, cancer-related fatigue and global side-effects as well as their mechanism of action are also discussed. In addition, we recapitulate an upcoming field of Ayurgenomics to understand the possible correlation of Prakriti with genetics as well as epigenetics. Conclusion: Both genetic as well as environmental factors have shown their linkage with cancer. Substantial advancements in the field of targeted therapies have opened new horizons for the cancer patients. To fight with this grave situation, a combination of ancient and modern medicinal systems seems to be the need of the hour
