Desempenho e características de carcaça de bovinos Nelore em confinamento alimentados com bagaço de cana-de-açúcar e diferentes fontes energéticas
Authors: Ezequiel Jane Maria Bertocco , Galati Rosemary Lais , Mendes Ana Rosália , Faturi Cristian
Published: January 2007

Avaliaram-se o ganho de peso e as características da carcaça de bovinos Nelore alimentados com bagaço de cana-de-açúcar (in natura ou hidrolisado) como volumoso e concentrado contendo farelo de gérmen de milho, casca do grão de soja ou polpa de citrus em substituição parcial (50%) ao milho. Quarenta bovinos Nelore (peso médio inicial de 340 kg e idade inicial de 32 meses) foram alimentados com quatro dietas fornecidas na proporção volumoso:concentrado 39:61. As fontes substitutivas do milho não afetaram o peso final (470,8; 478,6; 476,4 e 475,3 kg) e o ganho médio diário (1,1; 1,1; 1,1 e 1,2 kg/animal/dia). Não houve efeito sobre o rendimento de carcaça (55,3; 55,3; 54,0 e 54,8%), a área de Longissimus (24,2; 23,0; 25,0 e 23,2 cm²/100 kg de carcaça) e a espessura de gordura (4,4; 5,6; 4,7 e 4,4 mm). O menor custo por arroba foi observado no tratamento com polpa de citrus (R$ 44,20), seguido do farelo de gérmen de milho (R$ 48,80) e da casca de soja (R$ 50,80), porém, quando utilizado somente o milho, o custo da arroba foi de R$ 51,80. O milho moído pode ser parcialmente substituído pelo farelo de gérmen de milho, pela casca de soja ou pela polpa de citrus em dietas para bovinos em confinamento alimentados com bagaço de cana-de-açúcar (in natura ou hidrolisado) como volumoso, pois a substituição não alterou o ganho de peso e as características de carcaça.

Avaliou-se o efeito da suplementação com enzimas fibrolíticas (celulase e xilanase) sobre o consumo e a digestibilidade aparente total dos nutrientes de dietas compostas de silagem de milho e feno de tifton 85 (Cynodon spp.) cortado aos 90 dias. Oito bovinos (340 kg de PV) fistulados no rúmen foram distribuídos em dois quadrados latinos 4 x 4, em esquema fatorial 2 x 2 (fonte de volumoso e adição ou não de enzimas). O complexo enzimático testado foi proveniente de fonte comercial e extraído dos fungos Aspergillus niger e Trichoderma longibrachiatum, sendo fornecido na quantidade de 12 g/animal/dia, misturado à ração total. Não houve efeito da suplementação enzimática sobre o consumo de nutrientes para ambos os volumosos, porém, a adição de enzimas aumentou a digestibilidade total de FDN, FDA e CEL de 36,87; 36,21 e 46,89%, respectivamente, para 41,19; 40,01 e 50,46%, respectivamente.

Published: January 2007

OBJECTIVE: To histologically evaluate the behavior of the subcutaneous tissue of rats after placement of polyethylene tubes filled with calcium hydroxide-based root canal sealers (SealapexTM, ApexitTM e Sealer 26TM). STUDY DESIGN: The study employed 60 rats, which were divided into eight groups, being four experimental groups with 10 rats each, and four control groups with five rats. Analysis was conducted at 48 hours, 7, 21 and 60 days. RESULTS: Histological analysis revealed that all sealers were irritant; however, the intensity varied between each sealer and as a function of time. At the initial periods (48 hours and seven days), all materials demonstrated similar outcomes, with inflammatory reaction from severe to moderate, respectively. At the final periods (21 and 60 days), the tissue reactions to the implants containing SealapexTM displayed an active status yet with regression, compared to the ApexitTM and Sealer 26TM. The control groups exhibited less inflammatory cells than the experimental groups, keeping a reaction status with regression. CONCLUSIONS: The results achieved in this study revealed that the SealapexTM sealer was the most compatible, followed by ApexitTM and Sealer 26TM.

Reducing bioavailability and phytotoxicity of 2,4-dinitrotoluene by sorption on K-smectite clay
Authors: Roberts Michael G. , Rugh Clayton L. , Li Hui , Teppen Brian J. , Boyd Stephen A.
Published: January 2007

—Smectite clays demonstrate high affinities for nitroaromatics that strongly depend on the exchangeable cation. The K-smectites have high affinities for nitroaromatics, but Ca-smectites do not. Here we evaluate the ability of K-smectite to attenuate the bioavailability and hence toxicity of 2,4-dinitrotoluene (2,4-DNT) to the aquatic plant duckweed. In the absence of K-smectite, 2,4-DNT was highly toxic to duckweed. Small amounts of K-smectite reduced toxicity substantially, presumably by reducing 2,4-DNT bioavailability via sorption.
Metal-phytoplankton interactions: Modeling the effect of competing ions (H+, Ca2+, and Mg2+) on uranium uptake
Authors: Fortin Claude , Denison Frank H. , Garnier-Laplace Jacqueline
Published: January 2007

—The influence of pH and hardness cation concentrations on uranium uptake by a green alga, Chlamydomonas reinhardtii, was investigated through short-term exposure experiments. Uranium uptake at pH 5 and at pH 7 was measured over a large concentration range (0.020–2.0 μM 233U), and the effects of hardness cations were studied over environmentally pertinent concentration ranges (-0.05–2 mM) at a constant uranium concentration (0.25 μM). Calcium and magnesium inhibited uranyl uptake, but the influence of pH was more complex than anticipated. The equilibrium biotic ligand paradigm of metal bioavailability predicts that two distinct phenomena of antipathetic effect will influence uranium availability as pH is varied. Increasing pH reduces the concentration of protons, thus reducing competition for the physiologically active sites, whereas the concomitant complexation by carbonates and hydroxides reduces the free uranyl activity. Maximum uranium uptake rates observed at pH 7, however, were far greater than those observed at pH 5, suggesting a noncompetitive inhibition of metal transport by protons. Modeling on the basis of our results strongly suggests that cells grown and exposed at pH 7 have either a greater internalization rate of uranyl or a higher number of transport sites compared with cells grown and exposed at pH 5. We thus conclude that the simple proton—metal competition described by the biotic ligand model cannot successfully depict uranium—algae interactions. The development of an appropriate model incorporating the influence of protons to predict metal uptake and toxicity will be more challenging than anticipated.
A new method for unbiased time‐delay estimation in noisy environments
Authors: Wen Jing , Li Ping , Wen Yumei
Published: January 2007

When input data are contaminated with noise, the least mean square time‐delay estimation (LMSTDE) actually gives a biased estimate. In this paper, we propose and analyse a new adaptive filter structure for time‐delay estimation (TDE), which can eliminate this bias. A new adaptive criterion is then constructed. We determine the corresponding analytical solution, and develop the stochastic gradient algorithm to calculate the optimum solution. Convergence of the stochastic gradient algorithm is established, and upper bounds on the step sizes are deduced for guaranteed convergence. Simulation results are included to illustrate the superiority of the new model and corroborate the theoretical developments. Copyright © 2007 John Wiley & Sons, Ltd.
UV‐Light‐Driven Immobilization of Surface‐Functionalized Oxide Nanocrystals onto Silicon
Authors: Fanizza E. , Cozzoli P. D. , Curri M. L. , Striccoli M. , Sardella E. , Agostiano A.
Published: January 2007

TiO2 nanorods (NRs) and γ‐Fe2O3 nanocrystals (NCs) passivated with unsaturated long‐chain carboxylic acids, namely 10‐undecylenic acid (10UDA) and oleic acid (OLEA), are covalently anchored to Si(100) at room temperature by UV‐light‐driven reaction of hydrogenated silicon with the carbon–carbon double bond (–CC–) moieties of the capping surfactants. The high reactivity of vinyl groups towards Si provides a general tool for attaching particles of both materials via Si–C bonds. Interestingly, TiO2 NRs were efficiently attached to silicon even when capped by OLEA. This latter finding has been explained by a photocatalytic mechanism involving the primary role of hydroxyl radicals that can be generated upon bandgap TiO2 photoexcitation with UV light. The increased oxide coverage achievable on Si opens access to further surface manipulation, as demonstrated by the possibility of depositing an additional film of Au nanoparticles onto TiO2 via TiO2‐catalyzed visible‐light‐driven reduction of aqueous AuCl4– ions. Extensive morphological and chemical characterization of the obtained NC‐functionalized Si substrates is provided to support the effectiveness of proposed photochemical approaches.
Solution‐Processed Full‐Color Polymer Organic Light‐Emitting Diode Displays Fabricated by Direct Photolithography
Authors: Gather M. C. , Köhnen A. , Falcou A. , Becker H. , Meerholz K.
Published: January 2007

The first full‐color polymer organic light‐emitting diode (OLED) display is reported, fabricated by a direct photolithography process, that is, a process that allows direct structuring of the electroluminescent layer of the OLED by exposure to UV light. The required photosensitivity is introduced by attaching oxetane side groups to the backbone of red‐, green‐, and blue‐light‐emitting polymers. This allows for the use of photolithography to selectively crosslink thin films of these polymers. Hence the solution‐based process requires neither an additional etching step, as is the case for conventional photoresist lithography, nor does it rely on the use of prestructured substrates, which are required if ink‐jet printing is used to pixilate the emissive layer. The process allows for low‐cost display fabrication without sacrificing resolution: Structures with features in the range of 2 μm are obtained by patterning the emitting polymers via UV illumination through an ultrafine shadow mask. Compared to state‐of‐the‐art fluorescent OLEDs, the display prototype (pixel size 200 μm × 600 μm) presented here shows very good efficiency as well as good color saturation for all three colors. The application in solid‐state lighting is also possible: Pure white light [Commision Internationale de l'Éclairage (CIE) values of 0.33, 0.33 and color rendering index (CRI) of 76] is obtained at an efficiency of 5 cd A–1 by mixing the three colors in the appropriate ratio. For further enhancement of the device efficiency, an additional hole‐transport layer (HTL), which is also photo‐crosslinkable and therefore suitable to fabricate multilayer devices from solution, is embedded between the anode and the electroluminescent layer.
Quantity versus quality effects of generic advertising: The case of Norwegian salmon
Authors: Myrland Øystein , Dong Diansheng , Kaiser Harry M.
Published: January 2007

In this article, a two‐equation sample selection model is used to estimate a household demand function for salmon incorporating domestic generic advertising. The two‐equation estimation procedure, based on purchase and unit value equations, allows us to handle heavily censored panel data for salmon purchases by Norwegian households and the quality effects simultaneously. Unit values of the aggregated salmon commodity calculated from the observed expenditures and quantities are hypothesized to represent the average quality of the purchased commodity. Advertising effects on both purchases and unit values are investigated. The model also allows us to separate the effects of conditional purchases and purchase probabilities. Results indicate that most (76%) of the advertising effect is through the change of nonpurchase occasions to purchase occasions, and that generic salmon advertising induces Norwegian households to spend more money on salmon. However, advertising causes households to select more expensive products rather than increasing their purchased quantities. [EconLit citations: D12, C24]. © 2007 Wiley Periodicals, Inc.

Severe hypertelorism, midface prominence, prominent/simple ears, severe myopia, borderline intelligence, and bone fragility in two brothers: New syndrome?†
Authors: Hamamy Hanan A. , Teebi Ahmad S. , Oudjhane Kamaldine , Shegem N.N. , Ajlouni K.M.
Published: January 2007

We report on two brothers, born to double first cousin Jordanian Arab parents, with a syndrome comprising severe hypertelorism with upslanted palpebral fissures, brachycephaly, abnormal ears, sloping shoulders, enamel hypoplasia, and osteopenia with repeated fractures. Both have severe myopia, mild to moderate sensori‐neural hearing loss and borderline intelligence. Results of chromosome analysis were normal as was a FISH assay for subtelomeric rearrangements. The father has mild hypertelorism but the family history is otherwise unremarkable. We think that this represents a previously unrecognized autosomal or X‐linked recessive syndrome. © 2007 Wiley‐Liss, Inc.
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

KBG 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

We 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

That 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

Planar 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

The 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

We 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

Inspired 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

Background: 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.

Five 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.

Several 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.
