    Spatial information of excitatory neurons in APP/PS1 mice are decreased in dCA1 and vCA1. by Udaysankar Chockanathan (18510288)

    Published 2024
    “…<p>(A) In dCA1, spatial information was decreased in APP/PS1 mice relative to C57BL/6 controls (mean ± std: C57BL/6 = 0.134 ± 0.050, APP/PS1 = 0.132 ± 0.054, p < 0.01, two-sided Wilcoxon rank-sum test, n<sub>C57BL/6</sub> = 229 units from 5 recording sessions, n<sub>APP/PS1</sub> = 124 units from 4 recording sessions). …”

    A New Rotane Family:  Synthesis, Structure, Conformation, and Dynamics of [3.4]-, [4.4]-, [5.4]-, and [6.4]Rotane<sup>1</sup> by Lutz Fitjer (2466634)

    Published 1998
    “…All syntheses are based on bicyclobutylidene (<b>9</b>):  [2+1] cycloaddition of cyclobutylidene yields [3.4]rotane (<b>5</b>) (<b>9</b>−<b>5</b>), [2+2] cycloaddition of trimethyleneketene followed by spiroalkylation of the resulting trispiroketone <b>10</b> yields [4.4]rotane (<b>6</b>) (<b>9</b>−<b>10</b>−<b>13</b>−<b>14</b>−<b>6</b>), homologization of <b>10</b> via β-hydroxy selenides gives access to tetraspiroketone <b>11</b> and pentaspiroketone <b>12</b> (<b>10</b>−<b>15</b>−<b>11</b>−<b>16</b>−<b>12</b>), and further elaboration directed toward a cyclopropylcarbene−cyclobutene rearrangement yields [5.4]rotane (<b>7</b>) and [6.4]rotane (<b>8</b>) [<b>11</b>(<b>12</b>)−<b>18</b>(<b>24</b>)−<b>19</b>(<b>25</b>)−<b>20</b>(<b>26</b>)−<b>21</b>(<b>27</b>)−<b>22</b>(<b>28</b>)−<b>23</b>(<b>29</b>)−<b>7</b>(<b>8</b>)]. …”
