KBG syndrome: Report of twins, neurological characteristics, and delineation of diagnostic criteria
Authors: Skjei K.L. , Martin M.M. , Slavotinek A.M. 
Published: January 2007

AbstractKBG syndrome is a multiple congenital anomaly (MCA) syndrome comprising developmental delay, postnatal short stature, and delayed bone age. Many physical anomalies involving the face, hands, and costovertebral axis have been described in this syndrome. We present twin males with KBG syndrome and a review of 50 published case reports, with particular emphasis on the neurological aspects of KBG syndrome, including seizures, MRI findings, and behavior difficulties. It is argued that diagnostic criteria for KBG syndrome should include neurological involvement, that is, global developmental delay, seizures, and/or mental retardation (MR). The characteristic facial changes and representative hand and costovertebral anomalies are also defined. These diagnostic criteria were obtained from 50 publications and appeared to support the diagnosis in 43 cases. They will be helpful to pediatricians, geneticists, and neurologists in evaluating patients for this condition. © 2007 Wiley‐Liss, Inc.

Published: January 2007

AbstractWe report on a 42‐year‐old female patient with an interstitial 16 Mb deletion in 7q21.1‐21.3 and a balanced reciprocal translocation between chromosomes 6 and 7 [karyotype 46,XX,t(6;7)(q23.3;q32.3)del(7)(q21.1q21.3)de novo]. We characterized the size and position of the deletion by tiling path array comparative genomic hybridization (CGH), and we mapped the translocation breakpoints on chromosomes 6 and 7 by FISH. The clinical features of this patient—severe mental retardation, short stature, microcephaly and deafness—are in accordance with previously reported patients with 7q21 deletions. Chromosome band 7q21.3 harbors a locus for split hand/split foot malformation (SHFM1), and part of this locus, including the SHFM1 candidate genes SHFM1, DLX5, and DLX6, is deleted. The absence of limb abnormalities in this patient suggests either a location of the SHFM1 causing factor distal to this deletion, or reduced penetrance of haploinsufficiency of a SHFM1 factor within the deleted interval. © 2007 Wiley‐Liss, Inc.
Non‐genomic transgenerational inheritance of disease risk
Authors: Gluckman Peter D. , Hanson Mark A. , Beedle Alan S. 
Published: January 2007

AbstractThat there is a heritable or familial component of susceptibility to chronic non‐communicable diseases such as type 2 diabetes, obesity and cardiovascular disease is well established, but there is increasing evidence that some elements of such heritability are transmitted non‐genomically and that the processes whereby environmental influences act during early development to shape disease risk in later life can have effects beyond a single generation. Such heritability may operate through epigenetic mechanisms involving regulation of either imprinted or non‐imprinted genes but also through broader mechanisms related to parental physiology or behaviour. We review evidence and potential mechanisms for non‐genomic transgenerational inheritance of ‘lifestyle’ disease and propose that the ‘developmental origins of disease’ phenomenon is a maladaptive consequence of an ancestral mechanism of developmental plasticity that may have had adaptive value in the evolution of generalist species such as Homo sapiens.

Planar cell polarity signaling in vertebrates
Authors: Jones Chonnettia , Chen Ping 
Published: January 2007

AbstractPlanar cell polarity (PCP) refers to the polarization of a field of cells within the plane of a cell sheet. This form of polarization is required for diverse cellular processes in vertebrates, including convergent extension (CE), the establishment of PCP in epithelial tissues and ciliogenesis. Perhaps the most distinct example of vertebrate PCP is the uniform orientation of stereociliary bundles at the apices of sensory hair cells in the mammalian auditory sensory organ. The establishment of PCP in the mammalian cochlea occurs concurrently with CE in this ciliated epithelium, therefore linking three cellular processes regulated by the vertebrate PCP pathway in the same tissue and emerging as a model system for dissecting PCP signaling. This review summarizes the morphogenesis of this model system to assist the interpretation of the emerging data and proposes molecular mechanisms underlying PCP signaling in vertebrates.

Spam and the evolution of the fly's eye
Authors: Osorio Daniel 
Published: January 2007

AbstractThe open rhabdoms of the fly's eye enhance absolute sensitivity but to avoid compromising spatial acuity they require precise optical geometry and neural connections.1 This neural superposition system evolved from the ancestral insect eye, which has fused rhabdoms. A recent paper by Zelhof and co‐workers2 shows that the Drosophila gene spacemaker (spam) is necessary for development of open rhabdoms, and suggests that mutants revert to an ancestral state. Here I outline how open rhabdoms and neural superposition may have evolved via nocturnal intermediates, and discuss the implications for the role of spam in insect phylogeny.

Beyond treatment of individual behavior problems: an effective residential continuum of care for individuals with severe behavior problems
Authors: Page Terry J. , Perrin Frances A. , Tessing Jennifer L. , Vorndran Christina M. , Edmonds Danielle 
Published: January 2007

AbstractWe report on one component of a residential continuum of care designed to integrate children and adolescents with severe behavior problems into community residential and educational placements. The continuum featured three components: a behavior stabilization unit, campus apartments, and community group homes. Data are reported for a 5‐year period, during which 116 children and adolescents were admitted to a behavior stabilization program for treatment of severe self‐injury, aggression, and/or property destruction, and non‐compliance. Additional problems for some admissions included stereotypy, feeding disorders, sleeping disorders, seizure disorders, and other medical conditions. Archival data were collected retrospectively on age, gender, length of stay, prescribed medications, function of problem behaviors, acuity level of behavioral interventions, and discharge site. Analysis of data indicated (1) the behavior stabilization unit was successful in reducing occurrence of severe behavior problems, and increasing adaptive behaviors, (2) Seventy‐three individuals were able to successfully transition to a campus apartment program that had been designed as a step‐down program from the behavioral stabilization unit, and (3) Sixty‐seven individuals were able to transition to community group homes. The benefits of a residential continuum of care for individuals with severe behavior problems are discussed. Copyright © 2007 John Wiley & Sons, Ltd.
Droplets as Microreactors for High‐Throughput Biology
Authors: Taly Valerie , Kelly Bernard T. , Griffiths Andrew D. 
Published: January 2007

AbstractInspired by the principles of biological evolution, biologists—and others—have in recent decades harnessed the power of “natural” selection to sift through huge libraries of genes and find those with desirable properties. At the same time, the demand for high‐throughput biochemical and genetic assays and screens has driven the development of increasingly miniaturised assay systems. An exciting synergy is now emerging between these two fields, whereby the tools of ultrahigh‐throughput screening promise to open up new directions in molecular engineering.
Transradial approach for carotid artery stenting: A feasibility study
Authors: Folmar Jessica , Sachar Ravish , Mann Tift 
Published: January 2007

AbstractBackground: Carotid artery stenting (CAS) has become accepted as an alternative to carotid endarterectomy for revascularization of the internal carotid artery (ICA) among high risk patients. CAS from the femoral approach can be problematic due to access site complications as well as technical difficulties related to peripheral vascular disease (PVD) and/or anatomical variations of the aortic arch. The purpose of the present study is to evaluate the feasibility of the radial artery as an alternative approach for CAS. Methods: Forty‐two patients (mean age 71 ± 1, 26 male) underwent CAS. All had a CA stenosis greater than 80% and comorbid conditions increasing the risk of carotid endarterectomy. The target common carotid artery (CCA) was initially cannulated via the radial artery using a 5F Simmons 1 diagnostic catheter which was then advanced to the external CA (ECA) over an extrasupport 0.014” coronary guidewire. After removing the coronary guidewire, a 0.035” guidewire was advanced into the ECA, and the Simmons 1 was exchanged for a 5F or 6F shuttle sheath and positioned in the distal CCA. In four patients with a bovine aortic arch, the left CCA was accessed with a 5F Amplatz R2 catheter which was then exchanged for a shuttle sheath over a 0.035” guidewire. CAS was performed using standard techniques with weight‐based bivalirudin for anticoagulation. Results: CAS was successful in 35/42 (83%) patients, including 28/29 (97%) right CA, 4/5 (80%) bovine left CA, 7/13 (54%) left CA. Mean interventional time was 30 ± 3 minutes. The sheath was removed immediately after the procedure. There were no radial access site complications. One patient sustained a stroke 24 hrs after the procedure with complete resolution of symptoms (Mean NIH stroke scale 2.0 ± 0.3 before, 1.9 ± 0.3 after). Median hospital stay was 2 ± 0.6 days. Inadequate catheter support at the origin of the CCA was the technical cause of failure in the seven unsuccessful cases. Conclusion: CAS using the transradial approach appears to be safe and technically feasible. The technique may be particularly useful in patients with right ICA lesions and severe PVD or unfavorable arch anatomy, and among patients with a bovine aortic arch. © 2007 Wiley‐Liss, Inc.

AbstractFive CoII silicotungstate complexes are reported. The centrosymmetric heptanuclear compound K20[{(B‐β‐SiW9O33(OH))(β‐SiW8O29(OH)2)Co3(H2O)}2Co(H2O)2]⋅47 H2O (1) consists of two {(B‐β‐SiW9O33(OH))(β‐SiW8O29(OH)2)Co3(H2O)} units connected by a {CoO4(H2O)2} group. In the chiral species K7[Co1.5(H2O)7)][(γ‐SiW10O36)(β‐SiW8O30(OH))Co4(OH)(H2O)7]⋅36 H2O (2), a {γ‐SiW10O36} and a {β‐SiW8O30(OH)} unit enclose a mononuclear {CoO4(H2O)2} group and a {Co3O7(OH)(H2O)5} fragment. The two trinuclear CoII clusters present in 1 enclose a μ4‐O atom, while in 2 a μ3‐OH bridging group connects the three paramagnetic centers of the trinuclear unit, inducing significantly larger Co‐L‐Co (L=μ4‐O (1), μ3‐OH (2)) bridging angles in 2 (θav(Co‐L‐Co)=99.1°) than in 1 (θav(Co‐L‐Co)=92.8°). Weaker ferromagnetic interactions were found in 2 than in 1, in agreement with larger Co‐L‐Co angles in 2. The electrochemistry of 1 was studied in detail. The two chemically reversible redox couples observed in the positive potential domain were attributed to the redox processes of CoII centers, and indicated that two types of CoII centers in the structure were oxidized in separate waves. Redox activity of the seventh CoII center was not detected. Preliminary experiments indicated that 1 catalyzes the reduction of nitrite and NO. Remarkably, a reversible interaction exists with NO or related species. The hybrid tetranuclear complexes K5Na3[(A‐α‐SiW9O34)Co4(OH)3(CH3COO)3]⋅18 H2O (3) and K5Na3[(A‐α‐SiW9O34)Co4(OH)(N3)2(CH3COO)3]⋅18 H2O (4) were characterized: in both, a tetrahedral {Co4(L1)(L2)2(CH3COO)3} (3: L1=L2=OH; 4: L1=OH, L2=N3) unit capped the [A‐α‐SiW9O34]10− trivacant polyanion. The octanuclear complex K8Na8[(A‐α‐SiW9O34)2Co8(OH)6(H2O)2(CO3)3]⋅52 H2O (5), containing two {Co4O9(OH)3(H2O)} units, was also obtained. Compounds 2, 3, 4, and 5 were less stable than 1, but their partial electrochemical characterization was possible; the electronic effect expected for 3 and 4 was observed.

AbstractSeveral hexaazatrinaphthylene derivatives and a tris(thieno)hexaazatriphenylene derivative have been synthesised by reaction of the appropriate diamines with hexaketocyclohexane. The crystal structure of 2,3,8,9,14,15‐hexachloro‐5,6,11,12,17,18‐hexaazatrinaphthylene has been determined by X‐ray diffraction; this reveals a molecular structure in good agreement with that predicted by density functional theory (DFT) calculations and π‐stacking with an average spacing between adjacent molecular planes of 3.18 Å. Solid‐state ionisation potentials have been measured by using UV photoelectron spectroscopy and fall in the range of 5.99 to 7.76 eV, whereas solid‐state electron affinities, measured using inverse photoelectron spectroscopy, vary in the range −2.65 to −4.59 eV. The most easily reduced example is a tris(thieno)hexaazatriphenylene substituted with bis(trifluoromethyl)phenyl groups; DFT calculations suggest that the highly exothermic electron affinity is due both to the replacement of the outermost phenylene rings of hexaazatrinaphthylene with thieno groups and to the presence of electron‐withdrawing bis(trifluoromethyl)phenyl groups. The rather exothermic electron affinities, the potential for adopting π‐stacked structures and the low intramolecular reorganisation energies obtained by DFT calculations suggest that some of these molecules may be useful electron‐transport materials.
