In oceanic plankton, various hosts are capable of engulfing and temporarily integrating microalgae (photosymbiosis) or just their photosynthetic plastids (kleptoplastidy) from the environment. These cellular interactions have been hypothesized to be representative evolutionary steps in plastid acquisition eukaryotes, but underlying mechanisms not fully understood. Here, we studied a polar kleptoplastidic dinoflagellate, which is known steal microalga Phaeocystis antarctica. We tracked...

ABSTRACT Once the work at microscope is done, biological discoveries rely heavily on proper downstream analysis. This often amounts to first segmenting objects of interest in image before performing a quantitative Deep-learning (DL) nowadays ubiquitous such segmentation tasks. However, DL can be cumbersome apply, as it requires large amount manual labeling produce ground-truth data, and expert knowledge train models from scratch. Nonetheless, performance foundation models, although trained...

Proximal femur geometry is an important risk factor for diagnosing and predicting hip injuries. Hence, the development of automated approach measuring these parameters could help physicians with early identification ailments. This paper presents a technique that combines active shape model (ASM) deep learning methodologies. First, boundary extracted by neural network. Then, femur's anatomical landmarks are fitted to border using ASM method. Finally, geometric proximal femur, including neck...

SUMMARY In oceanic plankton, various host organisms are capable of engulfing and temporarily integrating microalgae (photosymbiosis) or just their photosynthetic plastids (kleptoplastidy) as a solar-powered energy source. These cellular interactions can be considered to representative evolutionary steps in plastid acquisition eukaryotes, but the underlying mechanisms dynamics not fully understood. Here, we studied kleptoplastidic dinoflagellate (RSD: Ross Sea Dinoflagellate), which is known...
