Jumping translocation in a phenotypically normal male: A study of mosaicism in spermatozoa, lymphocytes, and fibroblasts
Authors: Iwarsson Erik , Sahlén Sigrid , Nordgren Ann 
Published: July 2009

AbstractBoth Robertsonian translocations, rob(13;13) and rob(13;15), (in the present case defined as dic(13;15)), are rare chromosomal rearrangements and there is scarce information regarding their behavior during meiosis. In this report we describe a man with mosaicism for two cell lines, each cell line containing a different de novo Robertsonian translocation with the common breakpoint in the centromeric region on chromosome 13. The karyotype was finally defined as: 45,XY,rob(13;13)(q10;q10)[29]/45,XY,dic(13;15)(p11.2;p12)[22], a phenomenon referred to as jumping translocation. The relative occurrence of the two clones in lymphocytes and fibroblasts as well as the meiotic segregation in spermatozoa and the mechanism of formation were studied using karyotype analysis, fluorescence in situ hybridization (FISH), and quantitative fluorescence‐PCR. Karyotype analysis of cultured lymphocytes revealed 57% rob(13;13) cells and 43% dic(13;15) cells and for cultured skin fibroblasts the figures were almost identical (56% and 44%, respectively). FISH analysis showed 55% balanced nuclei for unselected spermatozoa and after swim‐up selection the number of balanced spermatozoa decreased to 41%. In addition, 16% of the unselected spermatozoa and 27% of the spermatozoa after swim‐up selection carried an additional chromosome 13, indicating a high risk for a trisomy 13 offspring. Swim‐up selection did not increase the number of balanced spermatozoa. © 2009 Wiley‐Liss, Inc.
Tidal interaction in High‐Mass X‐ray Binaries
Authors: Stoyanov K.A. , Zamanov R.K. 
Published: July 2009

AbstractOur aim is to investigate tidal interaction in High‐Mass X‐ray Binary stars in order to determine in which objects the rotation of the mass donors is synchronized or pseudosynchronized with the orbital motion of the compact companion. We calculate the pseudosynchronization period (Pps) and compare it with the rotational period of the mass donors (Prot). We find that (1) the Be/X‐ray binaries are not synchronized, the mass donors rotate faster than the orbital period and the ratio Pps/Prot is 2–300; (2) the giant and supergiant systems are close to synchronization and for them the ratio Pps/Prot is 0.3–2 (© 2009 WILEY‐VCH Verlag GmbH & Co.

Cosmic‐ray rejection for single spectroscopic CCD images by means of template matching
Authors: Wang C. , Zhu Z.Q. , Ye Z.F. 
Published: July 2009

AbstractThis article describes a novel algorithm for cosmic‐ray rejection in single spectroscopic CCD images. This algorithm is based on a variation of template matching. It focuses on identifying those pixels belong to spectra, while other conventional algorithms tried to locate the cosmic‐ray hits directly. The main principle is applying template matching to find suspicious blocks, which is followed by surface patching to locate the legitimate pixels accurately. Therefore, the rest pixels are the ones corrupted by cosmic‐ray hits. Meanwhile, almost all the parameters are automatically extracted from the images. Examples of its performance are given for both simulated and observed images. It shows an advantage of significantly low false alarm rate with relatively high detection rate (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Multiverses of the past
Authors: Trimble V. 
Published: July 2009

AbstractMore than 2000 years ago, Epicurus taught that there are an infinite number of other worlds, both like and unlike ours, and Aristotle taught that there are none. Neither hypothesis can currently be falsified, and some versions of current multiverses perhaps never can be, which has contributed to occasional claims that “this isn't science!” (a common complaint about cosmology for centuries). Define “cosmos”, or “world”, or “universe” to mean the largest structure of which you and the majority of knowledgeable contemporaries will admit to being a part. This begins with the small, earth‐centered worlds of ancient Egyptian paintings, Greek mythology, and Genesis, which a god could circumnavigate in a day and humans in a generation. These tend to expand and become helio‐rather than geo‐centric (not quite monotonically in time) and are succeeded by various assemblages of sun‐like stars with planets of their own. Finite vs. infinite assemblages are debated and then the issue of whether the Milky Way is unique (so that “island universes” made sense, even if you were against the idea) for a couple of centuries. Today one thinks as a rule of the entire 4‐dimensional space‐time we might in principle communicate with and all its contents. Beyond are the modern multi‐verses, sequential (cyclic or oscillating), hierarchical, or non‐communicating entities in more than four dimensions. Each of these has older analogues, and, in every milieu where the ideas have been discussed, there have been firm supporters and firm opponents, some of whose ideas are explored here. Because astronomical observations have firmly settled some earlier disputes in favor of very many galaxies and very many stars with planets, “other worlds” can now refer only to other planets like Earth or to other universes. The focus is on the latter (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Complexity in small‐scale dwarf spheroidal galaxies – Ludwig Biermann Award Lecture 2008
Authors: Koch A. 
Published: July 2009

AbstractOur knowledge about the dynamics, the chemical abundances and the evolutionary histories of the more luminous dwarf spheroidal (dSph) galaxies is constantly growing. However, very little is known about the enrichment of the ultra‐faint systems recently discovered in large numbers in large sky surveys. Current low‐resolution spectroscopy and photometric data indicate that these galaxies are highly dark matter dominated and predominantly metal poor. On the other hand, recent high‐resolution abundance analyses indicate that some dwarf galaxies experienced highly inhomogeneous chemical enrichment, where star formation proceeds locally on small scales. In this article, I will review the kinematic and chemical abundance information of the Milky Way satellite dSphs that is presently available from low‐ and high resolution spectroscopy. Moreover, some of the most peculiar element and inhomogeneous enrichment patterns will be discussed and related to the question of to what extent the faintest dSph candidates could have contributed to the Galactic halo, compared to more luminous systems (© 2009 WILEY‐VCH Verlag GmbH & Co.

New classification and basic stellar parameters of SU Equulei
Authors: Behre O. , Hempelmann A. 
Published: July 2009

AbstractThe variable star SU Equulei was classified as a close binary with an eclipse light curve previously categorized as WUMa type. The aim of this paper is a review of this old classification on the basis of new observations and a new determination of variable star ephemeris as well as the determination of SU Equ spectral type and distance. New photometric observations in different colours allow a precise determination of the period of variability and yield more accurate light curves allowing a re‐classification of the type of variability. We find the best period of variability to be half the old value. The shape of the light curve is inconsistent with an eclipse curve but consistent with an RR Lyrae type c classification. From the B, V, and R colours we deduce a new spectral classification. SU Equulei is an RRc Lyrae type variable of spectral class A8 at a distance of ≈12.4 kpc instead of a late‐type eclipsing binary (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
No effects of mobile phone electromagnetic field on auditory brainstem response
Authors: Kwon Myoung‐Soo , Jääskeläinen Satu K. , Toivo Tim , Hämäläinen Heikki 
Published: July 2009

AbstractThe present study investigated the possible effects of the electromagnetic field (EMF) emitted by an ordinary GSM mobile phone (902.4 MHz pulsed at 217 Hz) on brainstem auditory processing. Auditory brainstem responses (ABR) were recorded in 17 healthy young adults, without a mobile phone at baseline, and then with a mobile phone on the ear under EMF‐off and EMF‐on conditions. The amplitudes, latencies, and interwave intervals of the main ABR components (waves I, III, V) were compared among the three conditions. ABR waveforms showed no significant differences due to exposure, suggesting that short‐term exposure to mobile phone EMF did not affect the transmission of sensory stimuli from the cochlea up to the midbrain along the auditory nerve and brainstem auditory pathways.

Published: July 2009

AbstractA comparative study of Penicillium simplicissimum morphology and lipase production was performed using solid‐state (SSF) and submerged (SmF) fermentation. SSF was carried out on babassu cake as culture medium and SmF on a semi‐synthetic medium and a medium based on suspended babassu cake grains. Yield of product on biomass, specific activity and conidia production were 3.3‐, 1.3‐ and 2‐fold higher in SSF. In SmF, the type of fungus growth differed according to the medium. Using the semi‐synthetic medium, the fungus formed densely interwoven mycelial masses without conidia production, whereas using the babassu‐based medium the fungus formed free mycelia and adhered to the surfaces of the grains, producing conidia. The results show that babassu cake induces conidiation in SmF. In SSF, the fungus not only grew on the surface of the grains, producing conidia abundantly, but also effectively colonized and penetrated the babassu particles. The high conidia production and lipase productivity in SSF may be related to the low availability of nutrients or to other stimuli associated with this type of fermentation. Thus, the high production of the thermostable P. simplicissimum lipase, using a non‐supplemented, low‐cost agro‐industrial residue as the culture medium, demonstrates the biotechnological potential of SSF for the production of industrial enzymes.

Published: July 2009

AbstractThis review focuses on the construction of a global, comprehensive understanding of Bacillus subtilis through microarray studies. The microarray studies in B. subtilis were analysed based on the theme of the work, by mentioning the growth media, bioreactor operation conditions, RNA isolation method, number of data points analysed in exponential or stationary phases, compared genotypes, induction and repression ratios, investigated gene(s) and their positive and/or negative influences. Based on the theme and scope of the studies, the articles were reviewed under seven thematic sections, i.e., effects of gene deletion(s) or overexpression, effects of overexression of heterologous genes, comparison of global gene expression between aerobic and anaerobic respiration, effects of temperature change, effects of transported molecules, effects of limitations and stress conditions, and other microarray studies in B. subtilis.
Biotechnology in Turkey: An overview
Authors: Özdamar Tunçer H. 
Published: July 2009

AbstractThe term biotechnology first appeared in the programs of the Scientific and Technological Research Council of Turkey (TÜBİTAK) in 1982. The State Planning Organization (SPO) in 1988 defined biotechnology and the scientific fields. Moreover, it put forward an institutional framework and suggested priority areas for research and development. Turkey has been researching and investing in biotechnology for almost four decades. This review covers the development of science and technology policy with its history, consensus and consequences, bio‐industries in Turkey, and research activities in biotechnology at Turkish Universities. Details are provided by the research groups in response to a common request for information on their activities and major publications in the field. The information provided has been grouped under thematic topics within the broad theme of biotechnology, and summarized within these topics. Although many aspects of biotechnological research are being pursued in Turkey, it appears that the most common research activities of the field are in fermentation processes, environmental biotechnology, and biomedical engineering.
Juveniles' knowledge of the court process: results from instruction from an electronic source
Authors: Driver Christine , Brank Eve M. 
Published: July 2009

AbstractOur study first determined what juveniles know about the juvenile court process. Second, it evaluated a DVD designed to be a systematic and simple way to improve this knowledge. A pre‐ and posttest design was used with two pilot samples and two samples from the population of interest. A sample from a juvenile detention center (n = 118) was the focus of this study. Initial knowledge of the court process was quite low for the detention sample (pretest M = 64.0%, SD = 14.2%). All samples experienced a significant improvement of knowledge after watching the DVD. Youth in the detention sample had a mean improvement from pretest to posttest of 6.4% (SD = 11.9%), with mean scores at posttest being 70.3% (SD = 17.4%). Respondents varied in their performance on different question topics, scoring the lowest on questions related to what happens at juvenile court hearings. The social and demographic variables of age, race, gender, grades in school, number of previous arrests, and the number of times the respondent had been to court were evaluated through regression analysis. Age and race were found to be significantly related to pretest scores, and race was significantly related to improvement scores. Copyright © 2009 John Wiley & Sons, Ltd.
Effectiveness of a jail‐based treatment program for individuals with co‐occurring disorders
Authors: Rothbard Aileen B. , Wald Holly , Zubritsky Cynthia , Jaquette Nancy , Chhatre Sumedha 
Published: July 2009

AbstractObjective: This study examines the effectiveness of a county jail program for individuals with co‐occurring disorders (COD) in reducing rates of recidivism and increasing rates of engagement in community‐based treatment following discharge. Methods: Over a period of 30 months, between 2002 and 2004, 261 individuals who screened positive for COD voluntarily entered an in‐jail treatment program. The program provided integrated treatment for both mental health and substance abuse by therapists who had attended a state sponsored COD core training curriculum. The same program staff provided outpatient services once individuals were discharged. An observational study design was used to examine jail recidivism and community care as a function of intensity of treatment while in jail. All study participants had a minimum one year follow‐up. Data was obtained from a baseline comprehensive screening instrument, administrative claims data and county jail records. Logistic regression models were used to determine the likelihood of re‐incarceration and community engagement in treatment as a function of the number of treatment sessions provided by the jail program. Results: County jail records indicated that 47.5% were re‐incarcerated within 12 months of discharge. During the four and a half year period following the inception of the COD program 67% were re‐incarcerated, which was similar to the national three year recidivism rate. Fifty‐two percent (52%) attended a community‐based treatment program post discharge. The results of the regression analysis showed that a higher number of treatment sessions in the jail COD program was significant in reducing the rate of re‐incarceration but was not significant in predicting who would engage in outpatient treatment post discharge. Conclusions. Although the findings are promising, the evidence suggests that the jail treatment intervention may need to be more intense than the outpatient model used in this project given that the average length of stay in the jail program was 8 weeks due to release to the community. An alternative consideration would be to only provide the program to those inmates who are sentenced for at least 90 days. Copyright © 2009 John Wiley & Sons, Ltd.
Identification of gene disruptions for increased poly‐3‐hydroxybutyrate accumulation in Synechocystis PCC 6803
Authors: Tyo Keith E. J. , Jin Yong‐Su , Espinoza Freddy A. , Stephanopoulos Gregory 
Published: July 2009

AbstractInverse metabolic engineering (IME) is a combinatorial approach for identifying genotypes associated with a particular phenotype of interest. In this study, gene disruptions that increase the biosynthesis of poly‐3‐hydroxybutyrate (PHB) in the photosynthetic bacterium Synechocystis PCC6803 were identified. A Synechocystis mutant library was constructed by homologous recombination between the Synechocystis genome and a mutagenized genomic plasmid library generated through transposon insertion. Using a fluorescence‐activated cell sorting‐based high throughput screen, high PHB accumulating mutants from the library grown in different nutrient conditions were isolated and characterized. While several mutants isolated from the screen had increased PHB accumulation, transposon insertions in only two ORFs could be linked to increased PHB production. Disruptions of sll0461, coding for gamma‐glutamyl phosphate reductase (proA), and sll0565, a hypothetical protein, resulted in increased accumulation in standard growth media and acetate supplemented media. These genetic perturbations have increased PHB accumulation in Synechocystis and serve as markers for engineering increased polymer production in higher photosynthetic organisms. © 2009 American Institute of Chemical Engineers Biotechnol.

Transition‐Metal Complexes [(PMe3)2Cl2M(E)] and [(PMe3)2(CO)2M(E)] with Naked Group 14 Atoms (E=C–Sn) as Ligands; Part 1: Parent Compounds
Authors: Parameswaran Pattiyil , Frenking Gernot 
Published: July 2009

AbstractThe equilibrium geometries and bond dissociation energies of 16‐valence‐electron(VE) complexes [(PMe3)2Cl2M(E)] and 18‐VE complexes [(PMe3)2(CO)2M(E)] with M=Fe, Ru, Os and E=C, Si, Ge, Sn were calculated by using density functional theory at the BP86/TZ2P level. The nature of the ME bond was analyzed with the NBO charge decomposition analysis and the EDA energy‐decomposition analysis. The theoretical results predict that the heavier Group 14 complexes [(PMe3)2Cl2M(E)] and [(PMe3)2(CO)2M(E)] with E=Si, Ge, Sn have C2v equilibrium geometries in which the PMe3 ligands are in the axial positions. The complexes have strong ME bonds which are slightly stronger in the 16‐VE species 1ME than in the 18‐VE complexes 2ME. The calculated bond dissociation energies show that the ME bonds become weaker in both series in the order C>Si>Ge>Sn; the bond strength increases in the order Fe<Ru<Os for 1ME, whereas a U‐shaped trend Ru<Os<Fe is found for 2ME. The ME bonding analysis suggests that the 16‐VE complexes 1ME have two electron‐sharing bonds with σ and π symmetry and one donor–acceptor π bond like the carbon complex. Thus, the bonding situation is intermediate between a typical Fischer complex and a Schrock complex. In contrast, the 18‐VE complexes 2ME have donor–acceptor bonds, as suggested by the Dewar–Chatt–Duncanson model, with one M←E σ donor bond and two M→E π‐acceptor bonds, which are not degenerate. The shape of the frontier orbitals reveals that the HOMO−2 σ MO and the LUMO and LUMO+1 π* MOs of 1ME are very similar to the frontier orbitals of CO.
