Simulation and validation of ethanol removal from water in an adsorption packed bed: Isotherm and mass transfer parameter determination in batch studies
Authors: Jones R. A. , Thibault J. , Tezel F. H. 
Published: June 2010

AbstractPreferential adsorption of ethanol from ethanol/water mixtures in batch equilibrium and kinetic experiments were carried out on a commercially available activated carbon adsorbent Filtrasorb 600 (F‐600). A model based on finite difference method was developed and employed to determine the mass transfer parameters and equilibrium behaviour for the adsorption of ethanol from simple batch systems. The estimates of the adsorption isotherm along with the mass transfer parameters were used to simulate the transient performance that could be expected in a packed bed under various operating conditions (feed flow rate, feed concentration, and particle size). The applicability of the simulation results were found to be a good match with experimental packed bed experiments over the entire range of operating conditions tested.
Sympathetic innervation of the ileocecal junction in horses
Authors: Russo D. , Bombardi C. , Grandis A. , Furness J.B. , Spadari A. , Bernardini C. , Chiocchetti R. 
Published: June 2010

AbstractThe distribution and chemical phenotypes of sympathetic and dorsal root ganglion (DRG) neurons innervating the equine ileocecal junction (ICJ) were studied by combining retrograde tracing and immunohistochemistry. Immunoreactivity (IR) for tyrosine hydroxylase (TH), dopamine beta‐hydroxylase (DBH), neuronal nitric oxide synthase (nNOS), calcitonin gene‐related peptide (CGRP), substance P (SP), and neuropeptide Y (NPY) was investigated. Sympathetic neurons projecting to the ICJ were distributed within the celiac (CG), cranial mesenteric (CranMG), and caudal mesenteric (CaudMG) ganglia, as well as in the last ganglia of the thoracic sympathetic chain and in the splanchnic ganglia. In the CG and CranMG 91 ± 8% and 93 ± 12% of the neurons innervating the ICJ expressed TH‐ and DBH‐IR, respectively. In the CaudMG 90 ± 15% and 94 ± 5% of ICJ innervating neurons were TH‐ and DBH‐IR, respectively. Sympathetic (TH‐IR) fibers innervated the myenteric and submucosal ganglia, ileal blood vessels, and the muscle layers. They were more concentrated at the ICJ level and were also seen encircling myenteric plexus (MP) and submucosal plexus (SMP) descending neurons that were retrogradely labeled from the ICJ. Among the few retrogradely labeled DRG neurons, nNOS‐, CGRP‐, and SP‐IR nerve cells were observed. Dense networks of CGRP‐, nNOS‐, and SP‐IR varicosities were seen around retrogradely labeled prevertebral ganglia neurons. The CGRP‐IR fibers are probably the endings of neurons projecting from the intestine to the prevertebral ganglia. These findings indicate that this crucial region of the intestinal tract is strongly influenced by the sympathetic system and that sensory information of visceral origin influences the sympathetic control of the ICJ.

Long‐term regulation in calretinin staining in the rat inferior colliculus after unilateral auditory cortical ablation
Authors: Clarkson Cheryl , Juíz José M. , Merchán Miguel Á. 
Published: June 2010

AbstractIn this study we analyzed the effects in the inferior colliculus of a unilateral ablation of the auditory cortex in rats. Variations in both calretinin immunoreactivity and protein levels determined by Western blot suggest that such lesions induce changes in the regulation of this calcium‐binding protein. Stereological counts of calretinin‐immunoreactive neurons in the inferior colliculus 15, 90, and 180 days after the lesion showed a progressive increase in the number of immunoreactive neurons, with a parallel increase in the intensity of staining. Two hundred forty days after the cortical lesion, both the number of immunoreactive neurons and the staining intensity had returned to control values. The effects of the cortical lesion on calretinin regulation are more intense in those inferior colliculus subdivisions more densely innervated by the corticocollicular projection. This finding, along with the time course of calretinin regulation suggests that degeneration of the descending projection is linked to calretinin regulation in the inferior colliculus. We hypothesize, based on the role of calretinin, that the observed increase in immunoreactivity levels seen in the inferior colliculus after lesioning of the auditory cortex may be related to altered excitability in deafferented neurons. Our finding, may reflect adaptive mechanisms to changes in calcium influx and excitability in inferior colliculus neurons induced by lesions of the descending projection from the cortex to the inferior colliculus.

An explicit Schilder‐type theorem for super‐Brownian motions
Authors: Xiang Kai‐Nan 
Published: June 2010

AbstractLike ordinary Brownian motion, super‐Brownian motion, a central object in the theory of superprocesses, is a universal object arising in a variety of settings. Schilder‐type theorems and Cramér‐type theorems are two of the major topics for large‐deviation theory. A Schilder‐type (which is also a Cramér‐type) sample large deviation for super‐Brownian motions with a good rate function represented by a variation formula was established in 1993 and 1994; since then there have been very valuable contributions for giving an affirmative answer to the question of whether this sample large deviation holds with an explicit good rate function. In this paper, thanks to previous results on this issue and the Brownian snake, we establish such a large deviation for nonzero finite initial measures. © 2010 Wiley Periodicals, Inc.
Genome size, self‐organization and DNA's dark matter
Authors: Solé Ricard V. 
Published: June 2010

AbstractChromosomes exhibit several features indicating that its spatiotemporal dynamics is self‐organized. It has been recently suggested that a negative correlation between genome size and mean chromosome number would also be a fingerprint of selforganization, related to how human language is organized at the level of words and syllables. However, the vast dominance of non‐coding DNA in eukaryotic genomes should prevent an interpretation of genome/chromosome size based on functional trade‐offs related to information storage and transmission. Moreover, the reported negative correlation is shown to be an inevitable consequence of the definitions of chromosome and genome length and it is thus unrelated to any type of special generative process. © 2010 Wiley Periodicals, Inc.

A low distortion CMOS continuous‐time common‐mode feedback circuit
Authors: Lai Yen‐Tai , Lin Hung‐Yi 
Published: June 2010

AbstractIn high‐gain fully differential operational amplifier (FD op‐amp) design, the output common‐mode (CM) voltage of the FD op‐amp is quite sensitive to device properties and mismatch. It is, therefore, necessary to add an additional control circuit, referred to as the common‐mode feedback (CMFB) circuit, to stabilize the output CM voltage at some specified voltage. In this paper, we present a high linear CMOS continuous‐time CMFB circuit based on two differential pairs and the source degeneration using MOS transistors. Theoretical analysis and SPICE simulation results are provided to validate our proposed ideas. Finally, we present two design applications of the proposed configuration, one is the FD folded‐cascode op‐amp and the other is the Multiply‐by‐Two circuit which is the key component in the popular 1.5 bit/stage pipelined analog‐to‐digital converter. Comparison with conventional topologies shows that the new configuration has attractive characteristics concerning their implementation in high linear analog integrated circuits.

The Effect of an Electrical Bias on the Mechanism of Decomposition of Transients with Metal–Carbon σ Bonds
Authors: Rusonik Irena , Cohen Haim , Lugowskoy Alex , Krasnopolski Alexander , Zinigrad Michael , Meyerstein Dan 
Published: June 2010

AbstractWhen CCl3CO2– reacts thermally with porous iron electrodes, the radical ·CCl2CO2– is formed. This radical reacts with the surface of the electrode to form a transient with a Fe–C σ bond, Fe0(s)–CCl2COO–. The mechanism of decomposition of this transient depends on the electrical bias applied to the electrode: at a low bias of E > –0.9 V vs. SCE, HCCl2COO– is the major final product, whereas at a higher bias of E < –1.2 V vs. SCE, HC(O)CO2– is the major product.
A Template‐Mediated Click–Click Reaction: PNA–DNA, PNA–PNA (or Peptide) Ligation, and Single Nucleotide Discrimination
Authors: Peng Xiaohua , Li Hong , Seidman Michael 
Published: June 2010

AbstractA highly efficient chemical ligation was developed for quantitative conjugation of PNA with DNA (PNA or peptide) by using the copper‐catalyzed azide–alkyne cycloaddition reaction. Whereas PNAs with an alkyne at the C‐terminus and an azide at the N‐terminus have been used, an efficient click–click reaction occurs. The PNA click ligation is sequence specific and capable of single nucleotide discrimination.
Risk-based analysis of polychlorinated biphenyl toxicity in harbor seals

Abstract
Persistent organic pollutants (POPs) have been associated with adverse health effects in marine mammals. However, the complex mixtures to which free-ranging populations are exposed constrain the elucidation of cause-and-effect relationships between specific POPs and the observed health risks. In this study, we 1) assembled data from studies showing polychlorinated biphenyl (PCB)-associated effects on the health of free-ranging harbor seals in the northeastern Pacific Ocean, 2) carried out additional POP analyses on seal samples to broaden the available data on contaminant residues, and 3) derived estimates of individual POPs and their toxic risks. Taken together, these components were used to generate a new toxicity reference value (TRV) for the protection of marine mammal health. In this case study of seals in British Columbia, Canada, and Washington State, USA, PCBs were the single most abundant POP and were correlated with several adverse health effects. PCB exposures consistently exceeded regulatory toxicity thresholds for fish-eating wildlife. Nursing seal pups were at particular risk, reflecting their greatly increased dietary intake of PCBs and their sensitivity to developmental toxicity. Based on the collective evidence obtained, we propose TRVs (consisting of 5% tissue residue concentration and dose) of 1.3 mg/kg lipid weight tissue residue in blubber and 0.05 mg/kg lipid weight tolerable daily intake in prey. Insofar as the TRVs are lower than previously established TRVs and regulatory guidelines, our study highlights the current underestimation of risks associated with PCBs in high-trophic-level wildlife.

Published: June 2010

AbstractOvarian cancer has been associated in epidemiologic studies with postmenopausal hormone use. Whether associations differ by hormone regimen, current status or duration of use is unclear. We examined epithelial ovarian cancer incidence in relation to unopposed estrogen (E‐only) and estrogen plus progestin (E + P) among 54,436 postmenopausal women of the Cancer Prevention Study II Nutrition Cohort, a US cohort prospectively followed for cancer incidence since 1992. Demographic, medical, reproductive and lifestyle information was collected at enrollment and updated throughout follow‐up via self‐administered questionnaire. Extended Cox models were used to estimate age‐ and multivariate‐adjusted relative risk (RR) of ovarian cancer according to hormone regimen, current status and duration of use. During 15 years of follow‐up, 297 incident cases were identified. Relative to “never” use of hormones, current E‐only use was associated with a twofold higher risk [RR 2.07, 95% confidence interval (CI) 1.50–2.85]; each 5‐year increment of use was associated with a 25% higher risk (RR 1.25, 95% CI 1.15–1.36); ≥20 years of use was associated with a near threefold higher risk (RR 2.89; 95% CI 1.71–4.87; trend p = 0.01). Past E‐only use was not significantly associated with ovarian cancer, although a modest increase in risk per each 5‐year increment of use was suggested (RR 1.14, 95% CI 0.92–1.41). Neither current nor former E + P use was associated with ovarian cancer risk (RR 1.08, 95% CI 0.86–1.35; RR 1.08, 95% CI 0.68–1.71, respectively, per 5‐year increment). These findings suggest that progestins may mitigate some of the detrimental effects of estrogen on the ovarian epithelium.
