Anatomic evaluation is an important aspect of many studies in neuroscience; however, it often lacks information about the three-dimensional structure of the brain. Micro-CT imaging provides an excellent, nondestructive, method for the evaluation of brain structure, but current applications to neurophysiological or lesion studies require removal of the skull as well as hazardous chemicals, dehydration, or embedding, limiting their scalability and utility. Here we present a protocol using eosin in combination with bone decalcification to enhance contrast in the tissue and then employ monochromatic and propagation phase-contrast micro-CT imaging to enable the imaging of brain structure with the preservation of the surrounding skull. Instead of relying on descriptive, time-consuming, or subjective methods, we develop simple quantitative analyses to map the locations of recording electrodes and to characterize the presence and extent of hippocampal brain lesions.The transparency of animals is an important biological feature. Ascidian eggs have various degrees of transparency, but this characteristic has not yet been measured quantitatively and comprehensively. In this study, we established a method for evaluating the transparency of eggs to first characterize the transparency of ascidian eggs across different species and to infer a phylogenetic relationship among multiple taxa in the class Ascidiacea. We measured the transmittance of 199 eggs from 21 individuals using a hyperspectral camera. The spectrum of the visual range of wavelengths (400-760 nm) varied among individuals and we calculated each average transmittance of the visual range as bio-transparency. When combined with phylogenetic analysis based on the nuclear 18S rRNA and the mitochondrial cytochrome c oxidase subunit I gene sequences, the bio-transparencies of 13 species were derived from four different families Ascidiidae, Cionidae, Pyuridae, and Styelidae. The bio-transparency varied 10-90% and likely evolved independently in each family. Ascidiella aspersa showed extremely high (88.0 ± 1.6%) bio-transparency in eggs that was maintained in the "invisible" larva. In addition, it was indicated that species of the Ascidiidae family may have a phylogenetic constraint of egg transparency.In this study, we examined the fluctuation in radioresponse of HeLa cells during the cell cycle. For this purpose, we used HeLa cells expressing two types of fluorescent ubiquitination-based cell cycle indicators (Fucci), HeLa-Fucci (CA)2 and HeLa-Fucci (SA), and combined this approach with the micronucleus (MN) assay to assess radioresponse. The Fucci system distinguishes cell cycle phases based on the colour of fluorescence and cell morphology under live conditions. Time-lapse imaging allowed us to further identify sub-positions within the G1 and S phases at the time of irradiation by two independent means, and to quantitate the number of MNs by following each cell through M phase until the next G1 phase. Notably, we found that radioresponse was low in late G1 phase, but rapidly increased in early S phase. selleckchem It then decreased until late S phase and increased in G2 phase. For the first time, we demonstrated the unique fluctuation of radioresponse by the MN assay during the cell cycle in HeLa cells. We discuss the difference between previous clonogenic experiments using M phase-synchronised cell populations and ours, as well as the clinical implications of the present findings.The surface frustrated Lewis pairs (SFLPs) on defect-laden metal oxides provide catalytic sites to activate H2 and CO2 molecules and enable efficient gas-phase CO2 photocatalysis. Lattice engineering of metal oxides provides a useful strategy to tailor the reactivity of SFLPs. Herein, a one-step solvothermal synthesis is developed that enables isomorphic replacement of Lewis acidic site In3+ ions in In2O3 by single-site Bi3+ ions, thereby enhancing the propensity to activate CO2 molecules. The so-formed BixIn2-xO3 materials prove to be three orders of magnitude more photoactive for the reverse water gas shift reaction than In2O3 itself, while also exhibiting notable photoactivity towards methanol production. The increased solar absorption efficiency and efficient charge-separation and transfer of BixIn2-xO3 also contribute to the improved photocatalytic performance. These traits exemplify the opportunities that exist for atom-scale engineering in heterogeneous CO2 photocatalysis, another step towards the vision of the solar CO2 refinery.MADS-box genes are critical regulators of growth and development in flowering plants. Sequencing of the Musa balbisiana (B) genome has provided a platform for the systematic analysis of the MADS-box gene family in the important banana ancestor Musa balbisiana. Seventy-seven MADS-box genes, including 18 type I and 59 type II, were strictly identified from the banana (Pisang Klutuk Wulung, PKW, 2n = 2x = 22) B genome. These genes have been preferentially placed on the banana B genome. Evolutionary analysis suggested that M. balbisiana MCM1-AGAMOUS-DEFICIENS-SRF (MbMADS) might be organized into the MIKCc, MIKC*, Mα, Mβ, and Mγ groups according to the phylogeny. MIKCc was then further categorized into 10 subfamilies according to conserved motif and gene structure analyses. The well-defined MADS-box genes highlight gene birth and death in banana. MbMADSes originated from the same ancestor as MaMADSes. Transcriptome analysis in cultivated banana (ABB) revealed that MbMADSes were conserved and differentially expressed in several organs, in various fruit developing and ripening stages, and in stress treatments, indicating the participation of these genes in fruit development, ripening, and stress responses. Of note, SEP/AGL2 and AG, as well as other several type II MADS-box genes, including the STMADS11 and TM3/SOC1 subfamilies, indicated elevated expression throughout banana fruit development, ripening, and stress treatments, indicating their new parts in controlling fruit development and ripening. According to the co-expression network analysis, MbMADS75 interacted with bZIP and seven other transcription factors to perform its function. This systematic analysis reveals fruit development, ripening, and stress candidate MbMADSes genes for additional functional studies in plants, improving our understanding of the transcriptional regulation of MbMADSes genes and providing a base for genetic modification of MADS-mediated fruit development, ripening, and stress.
