Published: August 2011

AbstractJames Drake (1667–1707) was a renowned physician, anatomist, and writer whose name was recognized throughout London. He was highly involved in the politics of his time and was a well‐known pamphleteer. He also delved into comedies and plays. Drake became a fellow of the Royal Society and the College of Physicians before his early death at 40 years of age. He authored one of the most deservedly popular medical treatises of his time, Anthropologia Nova, which remained a valuable resource to physicians and anatomists alike for decades. The present article reviews the contributions of this little known name in the history of anatomy. Clin. Anat. 25:295–298, 2012. © 2011 Wiley Periodicals, Inc.
Correlation between patella and patellar tendon width: An anatomic study
Authors: Dundon J.M. , Markert R.J. , Lawless M.W. 
Published: August 2011

AbstractAnterior cruciate ligament (ACL) rupture is a common injury among orthopaedic patients with many different treatment modalities including bone‐patella‐bone autograft (BPBA) ACL reconstruction. Patella tendon width has been reported to be a predictor of recovery speed and success following BPBA repair. This study reports on the strength of the relationship between patella width and patella tendon width. Twenty fresh frozen cadavers were included in the study. Patella and patellar tendon measurements were recorded at the midpoint of the patellar tendon. Pearson correlation and linear regression were used to determine the relationship between patella width and patellar tendon width. Bivariate correlations with 95% confidence intervals and coefficients of determination (R2) are reported. The study used 20 cadavers, 12 men and 8 women with a mean age of 72 (standard deviation [SD] = 12; range = 44 to 87). The mean patella width was 49.24mm (SD = 4.11; range 42.33mm–56.33mm) while the mean patellar tendon width was 26.10mm (SD = 3.31; range 18.33mm–33.33mm). The correlation between patella width and patellar tendon width was 0.67 (95% confidence interval = 0.45 − 0.81). R2, the percent of variance in patellar tendon width accounted for by patella width, was 0.45. The regression equation for predicting patellar tendon width (y) yielded a formula of y = 0.536 + −0.316 × patella width. A moderate correlation exists between patella width and patellar tendon width. Our data suggests that this correlation is strongest with wider patellas and is more loosely associated with smaller patellas. Clin. Anat. 25:398–400, 2012. © 2011 Wiley Periodicals, Inc.
1,2‐Dihydrotriazinyl‐N‐oxy Free Radicals

Published: August 2011

AbstractTriazinyl‐N‐oxy free radicals, 2‐methyl‐2,4,6‐triphenyl‐1,2‐dihydro‐1,3,5‐triazinyl‐1‐oxy (6 a), 2,2,4,6‐tetraphenyl‐1,2‐dihydro‐1,3,5‐triazinyl‐1‐oxy (6 b), 2,2‐dimethyl‐4,6‐diphenyl‐1,2‐dihydro‐1,3,5‐triazinyl‐1‐oxy (13), and 2,6‐dimethyl‐2,4‐diphenyl‐1,2‐dihydro‐1,3,5‐triazinyl‐1‐oxy (14), in which the unpaired electron is delocalized over three nitrogen atoms, have been prepared and characterized. A method has been devised for introducing an N‐oxide function into the triazinyl core. Then, by using a Grignard reagent, substitution α to the N‐oxide group was achieved and the resulting 1,2‐dihydrotriazine‐N‐oxide oxidized into the corresponding nitroxide. Solution EPR spectra exhibit hyperfine splitting that confirms spin delocalization over the three nitrogen atoms of the triazinyl ring. They also show that spin delocalization diminishes with increasing distance for the coupling and is largest for nitrogen N1 and weakest for N5. Free radicals 6 a and 13 are stable in the solid state and have been characterized by X‐ray diffraction, but they tend to gradually degrade in solution. In the solid state, these two free radicals are arranged into antiferromagnetically exchange‐coupled pairs, J=−5.2(6) for 6 a and −3.7(4) cm−1 for 13 (H=−2 JS1S2).
Synthesis of 3,7‐Disubstituted Imipramines by Palladium‐Catalysed Amination/Cyclisation and Evaluation of Their Inhibition of Monoamine Transporters
Authors: Christensen Helle , Schjøth‐Eskesen Christina , Jensen Marie , Sinning Steffen , Jensen Henrik H. 
Published: August 2011

AbstractWe describe a novel approach for the synthesis of a series of 3,7‐difunctionalised symmetric and unsymmetrical analogues of the tricyclic antidepressant (TCA) imipramine, which uses a key palladium‐catalysed amination/cyclisation of an ester‐functionalised dibromide. Of the ester, methyl, hydroxymethyl and methoxymethyl disubstituted compounds prepared, 3,7‐dimethyl‐imipramine was found to be the most potent against the human serotonin transporter (hSERT). The inhibitory potency of 3,7‐dimethyl imipramine was found to be at least as high as the parent imipramine. This novel TCA also exhibits an increased selectivity (relative to imipramine) in binding to hSERT versus the human norepinephrine transporter (hNET). Even higher selectivity could be obtained with 3,7‐dihydroxymethyl imipramine, which was found to be 167‐fold more selective for hSERT over hNET, representative of a 120‐fold gain in selectivity relative to the parent imipramine. These results further validate our previous model for the binding of imipramine and high‐affinity analogues of imipramine to the central binding site of hSERT.
Isothiourea‐Catalysed Asymmetric C‐Acylation of Silyl Ketene Acetals
Authors: Woods Philip A. , Morrill Louis C. , Bragg Ryan A. , Smith Andrew D. 
Published: August 2011

AbstractScreening of a range of chiral isothioureas and acyl donors to promote the asymmetric C‐acylation of silyl ketene acetals indicates that C(2)‐aryl‐dihydropyrimidobenzothiazole‐derived isothioureas and propionic anhydride give optimal reactivity and enantioselectivity in this process. Under optimised conditions 3‐acyl‐3‐aryl or 3‐acyl‐3‐alkylfuranones are prepared in good yields and moderate to excellent enantioselectivities (up to 98 % ee; ee=enantiomeric excess).
