AbstractThis work aims to evaluate for the enantiomeric separations of three agrochemical toxins: haloxyfop‐methyl, fenoxaprop‐p‐ethyl and indoxacarb on crystalline degradation products–chiral stationary phase (CDP‐CSP) of high‐performance liquid chromatography (HPLC) under normal and polar organic phases. In the normal phase, the mobile phase was n‐hexane with alcohols including methanol and isopropanol as polar modifiers. In the polar organic phase mode, the mobile phase was methanol with different percentages of triethylammunium acetate. The influence of flow rate (0.3–0.9 mL/min), analyte concentration and silica gel particle sizes (10, 15 and 30 µm) was investigated. This new chiral stationary phase showed excellent stereoselectivity for the two enantiomers of haloxyfop‐methyl and fenoxaprop‐p‐ethyl and chiral recognition for indoxacarb under normal‐phase mode. However, under polar organic phase, only indoxacarb was separated (α < 1.5). The chromatographic results were compared with commercial chiral columns. Copyright © 2007 John Wiley & Sons, Ltd.
The poor, the Black, and the marginalized as the source of cadavers in United States anatomical education
Authors: Halperin Edward C. 
Published: January 2007

AbstractWhen the practice of hands‐on anatomical dissection became popular in United States medical education in the late 18th and early 19th centuries, demand for cadavers exceeded the supply. Slave bodies and thefts by grave robbers met this demand. Members of the public were aware that graves were being robbed and countered with various protective measures. Since the deterrence of grave robbing took time and money, those elements of society who were least economically and socially advantaged were the most vulnerable. Enslaved and free African Americans, immigrants, and the poor were frequently the target of grave robbing. The politically powerful tolerated this behavior except when it affected their own burial sites. Slave owners sold the bodies of their deceased chattel to medical schools for anatomic dissection. Stories of the “night doctors” buying and stealing bodies became part of African American folklore traditions. The physical and documentary evidence demonstrates the disproportionate use of the bodies of the poor, the Black, and the marginalized in furthering the medical education of white elites. Clin.

Bony eminence on the middle cranial fossa corresponding to the temporomandibular joint

Published: January 2007

AbstractWe report a nameless bony eminence over the temporomandibular joint (TMJ) and its possible clinical significance. Forty‐two half heads of 21 UK Caucasian cadavers (61–95 years old, mean 84.3 ± 8.2 years, male:female = 11:10) were used to investigate the surface of the middle cranial fossa (MCF) over the TMJ. The thickness of the bony roof of the glenoid fossa was also measured. A bony eminence over the glenoid fossa was observed in half of the specimens. Some showed a complete oval bulge, which completely reflected the contour of the glenoid fossa. The others showed a bony bulge, which partially reflected that contour. The mean (±SD) thickness of the bone in the roof of glenoid fossa was 1.5 ± 1.2 mm. The mean bony thickness of specimens showing the eminence was 0.8 ± 0.5 mm, whereas it was 2.3 ± 1.2 mm in specimens without an eminence. These differences were statistically significant (P < 0.01). The osteological features we describe may be relevant to certain clinical problems. Traumatic dislocation of mandibular condyle, for example, might relate to a weakness of the glenoid fossa. Clin.

Avulsion of ascending lumbar and iliolumbar veins in anterior spinal surgery: An anatomical study
Authors: Sivakumar G. , Paluzzi A. , Freeman B. 
Published: January 2007

AbstractTo expose the disc between the 4th and 5th lumbar vertebrae in anterior spinal surgery, left to right retraction of inferior vena cava and aorta is required. This manoeuvre can be complicated by venous haemorrhage that, in most cases, is due to avulsion of the left ascending lumbar vein (ALV) or the left iliolumbar vein (ILV). We dissected 23 embalmed cadavers to assess the factors that contribute to the risk of tearing these two veins during retraction. We describe a triangular region that should help surgeons in identifying the ALV and ILV. This triangle is defined by the lateral border of the common iliac vein, the medial border of the psoas major muscle, and the superior end‐plate of the L5 vertebral body. We observed that 3 cm between the termination of the left ALV, or a common stem with the ILV, and the termination of the common iliac vein is the critical distance, less than which the risk of venous avulsion is highest. Although the sample considered is small, our study seems to suggest that male patients tend to have a higher risk of venous avulsion than female patients. Clin.

Chemical Micropatterning of Polycarbonate for Site‐Specific Peptide Immobilization and Biomolecular Interactions

Published: January 2007

AbstractPolycarbonate (PC) is a useful substrate for the preparation of microfluidic devices. Recently, its utility in bioanalysis has attracted much attention owing to the possibility of using compact discs as platforms for the high‐throughput analysis of biomolecular interactions. In this article we report a novel method for the chemical micropatterning of polycarbonate based on the printing of functionalized silica nanoparticles. The semicarbazide groups present on the surface of the nanoparticles were used for the site‐specific semicarbazone ligation of unprotected peptides derivatized by an α‐oxoaldehyde group. The peptide micropatterns permitted the specific capture of antibodies. We report also the characterization of micropatterns on PC by using a wide‐field optical imaging technique called Sarfus; this allows the detection of nm‐thick films by using nonreflecting PC substrates and an optical microscope working with reflected differential interference contrast. The method described here is an easy way to modify polycarbonate surfaces for biomolecular interaction studies and should stimulate the use of PC for developing plastic biosensors.
Ruthenium–Lewis Acid Catalyzed Asymmetric Diels–Alder Reactions between Dienes and α,β‐Unsaturated Ketones

Published: January 2007

AbstractThe complex [Ru(Cp)(R,R‐BIPHOP‐F)(acetone)][SbF6], (R,R)‐1 a, was used as catalyst for asymmetric Diels–Alder reactions between dienes (cyclopentadiene, methylcyclopentadiene, isoprene, 2,3‐dimethylbutadiene) and α,β‐unsaturated ketones (methyl vinyl ketone (MVK), ethyl vinyl ketone, divinyl ketone, α‐bromovinyl methyl ketone and α‐chlorovinyl methyl ketone). The cycloaddition products were obtained in yields of 50–90 % and with enantioselectivities up to 96 %ee. Ethyl vinyl ketone, divinyl ketone and the halogenated vinyl ketones worked best and their reactions with acyclic dienes consistently provided products with >90 %ee. α‐Chlorovinyl methyl ketone performed better than α‐bromovinyl methyl ketone. The reaction also provided a [4.3.1]bicyclic ring system in 95 %eethrough an intramolecular cycloaddition reaction. Crystal structure determinations of [Ru(Cp)((S,S)‐BIPHOP‐F)(mvk)][SbF6], (S,S)‐1 b, and [Ru(Cp)((R,R)‐Me4BIPHOP‐F)(acrolein)][SbF6], (R,R)‐2 b, provided the basis for a rationalization of the asymmetric induction.
Self‐Assembly of an Alkylated Guanosine Derivative into Ordered Supramolecular Nanoribbons in Solution and on Solid Surfaces

AbstractWe report on the synthesis and self‐assembly of a guanosine derivative bearing an alkyloxy side group under different environmental conditions. This derivative was found to spontaneously form ordered supramolecular nanoribbons in which the individual nucleobases are interacting through H‐bonds. In toluene and chloroform solutions the formation of gel‐like liquid‐crystalline phases was observed. Sub‐molecularly resolved scanning tunneling microscopic imaging of monolayers physisorbed at the graphite–solution interface revealed highly ordered two‐dimensional networks. The recorded intramolecular contrast can be ascribed to the electronic properties of the different moieties composing the molecule, as proven by quantum‐chemical calculations. This self‐assembly behavior is in excellent agreement with that of 5′‐O‐acylated guanosines, which are also characterized by a self‐assembled motif of guanosines that resembles parallel ribbons. Therefore, for guanosine derivatives (without sterically demanding groups on the guanine base) the formation of supramolecular nanoribbons in solution, in the solid state, and on flat surfaces is universal. This result is truly important in view of the electronic properties of these supramolecular anisotropic architectures and thus for potential applications in the fields of nano‐ and opto‐electronics.
