FIGURES 32–45: The sexual reproduction, the auxospore development and the formation of initial cells. All scale bars = 10 µm. Fig. 32. Two paired cells in different size. Fig. 33. Two gametes (arrowheads) were formed in one gametangia. Fig. 34. The trans anisogamy? was occurred. One zygote (arrow) was formed in a theca (right) of gametangia and two unfused gametes (arrowheads). Fig. 35. Two zygotes were formed after the gametes fusing. Fig. 36. Two zygotes were released from thecae of gametangia. Fig. 37. Younger auxospores paired more or less parallel to each other. Note the slightly convex center (arrow). Fig. 38. Matured auxospores. Two chloroplasts (arrow) appressed to the wall of auxospores. The longitudinal bands also could been found (arrowhead). Figs 39–40. Formation of initial cells. A theca was present in the left auxospore (arrowhead) in fig. 39. During the formation of initial cells, the two chloroplasts show strongly contraction (arrows) Fig. 41. In new formed initial cells, two elongate chloroplasts apressed to the girdle. One chloroplast projects to another one along the hyaline connection between them (arrow). Figs 42–43. The initial cells completely formed in the two auxospores. The two chloroplasts nearly fused (arrow) in the right initial cell (fig. 42). The H-shaped chloroplast (arrow) already formed in the left initial cell (fig. 43). Fig. 44. The initial cell were escaping from the perizonium. Note the transverse perizonial bands (arrowhead), cape (=incunabular cap, arrow) and probably longitudinal band (double arrows). Fig. 45. The empty perizonium with two broken poles.

Curated set of cone bipolar cell morphologies for biophysical modelling
<p>This dataset contains 40 cone bipolar cell morphologies in the .swc file format (skeleton and radius) based on the e2006 EM dataset (Helmstaedter et al., 2013). All morphologies have been manually proof-read. Individual file names consist of the cell ID from the original EM dataset and the cell type following (Behrens et al., 2016).</p>
METHODS. Bovine ilia were used in the simulations because their histological structure (a fibrolamellar cortex overlying cancellous bone26) was found to match that of the Triceratops ilium. Bone sections 10 x 50 x 縠 3.0 cm with cortices ranging from 0.5 to 5.5 mm in depth (the range of initial cortical-thickness estimates based on gross morphology) were mounted on a servohydraulic mechanical loading frame (MTS Bionix, Minneapolis) and penetrated with an aluminium-bronze T. rex tooth replica. The replica was cast from an actual adult T. rex maxillary tooth, after casts made from some ofthe deeper bite marks revealed the size and shape of the teeth that had impacted the pelvis8 • The replica was penetrated into the ilia sections at 1 mm s-1 to a depth of 11.5 mm, equivalent to the maximum depth of the deepest ilium bite mark8 • Forces were measured with an MTS 25 N strain-gauge-based axial load cell accurate to 0.2%. The forces increased with increasing penetration depth even after the cortical layer had been perforated and the underlying cancellous bone was being crushed. The increase in force with penetration depth is attributed to a greater cortical surface area coming into contact with the semi-conical penetrator tooth as it descended through the ilia. in Bite-force estimation for Tyrannosaurus rex from tooth-marked bones

Unveiling CNS Cell Morphology with Deep Learning: A Gateway to Anti-Inflammatory Compound Screening
<p>Understanding the connection between cellular structure and observable traits is vital for comprehending cell behavior, especially in neuropathological conditions. Current limitations exist in applying advanced image analysis, like deep learning, to central nervous system cells due to challenges such as the need for extensive labeled data, difficulty in detecting subtle changes, and the presence of batch effects. The study focuses on overcoming these issues in the context of neuroinflammation, utilizing a deep learning approach to effectively analyze morphological changes in neuronal and microglial cells. This innovative method aids in studying neuroinflammation, facilitating the screening of potential therapeutic compounds and bridging gaps in neuropathological research and pharmaceutical development.</p>
