Likely, segmentation won't produce good results. This is mostly due to difficult tracking for these bundles.<br>- The CC are split for each lobe. However, for technical consideration, the frontal portion was split in two to facilitate clustering and segmentation. For the same reason, the portion fanning to the pre/post central gyri were separated.<br>- The streamlines present in the CC are homotopic, Recobundles will allow for variation and thus lead to 'some' heterotopy. However, it is expected that the results will be mostly homotopic.<br>- CG has 3 possible endpoint locations. However, the full extent of the tail is difficult to track and is often missing.<br>- FPT and POPT should terminate in the pons. However, to fully capture candidate streamlines and improve segmentation quality even streamlines reaching down the brainstem are selected. <br>- PYT should reach down the brainstem. For similar reasons to the FPT/POPT, streamlines ending in the pons are selected. Otherwise, fanning is affected and bundles is too skinny. <br>- OR_ML will most likely have difficulty capturing the full ML. However, this is often due to difficult tracking.<br>- The cerebellum is often cut due to acquisition FOV. In such a case, all projection bundles will be more difficult to recognize and most cerebellum bundles will be missing (ICP, MCP, SCP).</p> <p>See Mosaic of bundles <a href="https://i.ibb.co/n7Ln3Gf/mosaic-local.png"><strong>here</strong></a>.</p> <p><strong>Acronym</strong><br>AC - Anterior commisure<br>AF - Arcuate fasciculus<br>CC_Fr_1 - Corpus callosum, Frontal lobe (most anterior part)<br>CC_Fr_2 - Corpus callosum, Frontal lobe (most posterior part)<br>CC_Oc - Corpus callosum, Occipital lobe<br>CC_Pa - Corpus callosum, Parietal lobe<br>CC_Pr_Po - Corpus callosum, Pre/Post central gyri<br>CC_Te - Corpus callosum, Temporal lobe<br>CG - Cingulum<br>FAT - Frontal aslant tract<br>FPT - Fronto-pontine tract<br>FX - Fornix<br>ICP - Inferior cerebellar peduncle<br>IFOF - Inferior fronto-occipital fasciculus<br>ILF - Inferior longitudinal fasciculus<br>MCP - Middle cerebellar peduncle<br>MdLF - Middle longitudinal fascicle<br>OR_ML - Optic radiation and Meyer's loop<br>PC - Posterior commisure<br>POPT - parieto-occipito pontine tract<br>PYT - Pyramidal tract<br>SCP - Superior cerebellar peduncle<br>SLF - Superior longitudinal fasciculus<br>UF - Uncinate fasciculus</p>
Male song structure predicts offspring recruitment to the breeding population in a migratory bird
<p>Bird song is a classic example of a sexually selected trait, but much of the work relating individual song components to fitness has not accounted for song typically being composed of multiple, often-correlated components, necessitating a multivariate approach. We explored the role of sexual selection in shaping complex male song of house wrens (<em>Troglodytes aedon</em>) by simultaneously relating its multiple components to fitness using multivariate selection analysis, which is widely used in insect and anuran studies but not in birds. The analysis revealed significant variation in the form and strength of selection acting on song across different selection episodes, from nest-site defense to recruitment of offspring to the breeding population. Males that sang more song typically employed in close communication sired more offspring that were subsequently recruited to the breeding population than those that sang far-communication song. However, this relationship was not consistent across earlier selection episodes, as evidenced by non-linear selection acting on these song components in other contexts. Collectively, our results present a complex picture of multivariate selection on male song structure that would not be evident using univariate approaches and suggest possible trade-offs within and among song components at different points of the breeding season. </p>

Micro-CT image of cell-populated collagen scaffold in the aqueous environment (contrasted with PTA)
<p>A dataset of the collagen scaffold populated with the 3T3 cells scanned in the aqueous environment using Bruker Skyscan 1276 machine (Bruker, Belgium). </p><p><strong>Scaffold production</strong></p><p>The processes of obtaining and working with collagen scaffolds were conducted in an isolated environment under sterile conditions. The collagen sponge matrix was manufactured at the Center for Collagen Innovation within the Institute of Regenerative Medicine at Sechenov University and provided to us for experimental purposes. In order to obtain the collagen, the authors utilized animal-derived materials sourced from the tendons of large horned cattle. To do this, the tendons were cleaned of excess tissues, cut into pieces with a thickness of 0.5-1 cm, and sequentially treated for 12 hours in a 0.5 M NaCl solution. Subsequently, the mass was homogenized in a 0.83 M acetic acid solution. The resulting suspension was hydrolyzed with 0.24% pepsin for 2 days, after which 1 M NaOH was added to adjust the pH to 7.5, halting the hydrolysis process. The suspension was precipitated with a 12% NaCl solution, the resulting precipitate was redissolved in 0.02 M acetic acid, and then dialyzed. To obtain collagen porous matrices (sponges), the obtained solution was neutralized using 0.1 M NaOH until a pH of 7-7.5 was reached, and the resulting suspension was lyophilized at -40°C for 2 days.</p><p>Subsequently, the collagen matrix was cut into cubes with sides measuring 0.5 cm. These cubes were placed in 15 ml test tubes filled with 70% ethyl alcohol for sterilization. The test tubes were then placed on a shaker and left in the refrigerator at +4°C for 24 hours. Afterward, the collagen matrices were removed from the alcohol and rinsed five times with 0.9% NaCl.</p><p>Following the alcohol rinse to confirm the absence of toxicity, an elution test, adapted following the ISO 10993 protocol, was conducted. To obtain collagen cube extracts, they were incubated in a cell culture medium at a volume of 1 ml per sample for 24 hours at 37°C. The 3T3 cell culture was passaged, with 5000 cells seeded in each well of a 96-well plate. After 24 hours, the cells were treated with extract at a volume of 200 µl per well and left in the incubator at 37°C for 24 hours. The following day, extracts were collected, and AlamarBlue reagent (Invitrogen, Waltham, MA, USA) was added according to the manufacturer's instructions to assess the metabolic activity of the cells. Serial dilutions of sodium dodecyl sulfate (SDS) were used as the positive control. Fluorescence intensity was measured using a Victor Nivo spectrofluorimeter (PerkinElmer, Waltham, Massachusetts, USA) at an excitation wavelength of 530 nm and an emission wavelength of 590 nm.</p><p><strong>Cell seeding</strong></p><p>After confirming the absence of cytotoxic effects, collagen sponges were seeded with the NIH 3T3 cell line at a density of 50,000 cells per sample (cubes of collagen sponge measuring 0.5 cm per side). </p><p><strong>Staining technique</strong></p><p>Fixed specimens in 10% formalin with PBS were washed after 24 hours with distilled water and after that placed in 3% phosphotungstic acid dissolved in distilled water for 24 hours and kept on the rotary shaker at room temperature. After staining, samples were washed and stored in distilled water at 5 °C. </p><p><strong>Image acquisition and reconstruction</strong></p><p>A plastic tube filled with distilled water containing the contrasted sample was placed on the sample holder in a SkyScan 1276 micro-CT (Bruker, Kontich, Belgium) and were scanned at 3 μm voxel resolution with 70 kV voltage and 200 uA source power and an aluminum filter with 1 mm of thickness. The rotation was set to 360° around the vertical axis of the sample, with two middle frames for each 0.2° angle step.</p><p>After scanning, the data were reconstructed using Bruker's NRecon software. During reconstruction, the ring artifact reduction value was set to 20% and the beam hardening correction value to 30%. After that, samples were exported as a series of 16-bit TIFF images which could be opened in the specialized software. </p>
