Theoretical study of stability and electronic structure of Li(Mg,Zn)N alloys: A candidate for solid state lighting (2007)

Using selective chemical mutation, we propose and investigate the electronic structure of an alloy with the potential to fill the green gap left open by existing InGaN based emission devices. The small mismatch between LiMgN and LiZnN, along with electronic band gaps spanning the visible range, makes them good candidates. Calculations are performed using a first-principles band structure method, with the special quasirandom structure approach employed to generate the random alloys. Comparison of LiMgN and LiZnN with their binary nitride analogs is made, and the energetic and electronic effects of alloy ordering are investigated. These alloys exhibit negative mixing enthalpies atypical of traditional binary nitride systems, which is explained in terms of the low lattice strain and the chemical bonding effects of the interstitial Li ions.
The Chromium, Manganese, and Cobalt Complexes of Transferrin (1969)

The two metal-binding sites of transferrin will form specific complexes with chromium, manganese, and cobalt ions. Each complex binds bicarbonate in a ratio to the metal ion near unity. In addition to characteristic optical absorption bands in the visible region a specific absorption near 295 mµ is observable for all complexes by difference spectrophotometry. Static magnetic susceptibility measurements indicate that each of the metal ions is bound in the trivalent state, with the cobalt in the low spin diamagnetic form. A distinct difference between the two sites is evident by electron paramagnetic resonance spectroscopy when chromium is bound.
Solution of Two-Dimensional Riemann Problems of Gas Dynamics by Positive Schemes (1998)

The positivity principle and positive schemes to solve multidimensional hyperbolic systems of conservation laws have been introduced in [X.-D. Liu and P. D. Lax, J. Fluid Dynam., 5 (1996), pp. 133--156]. Some numerical experiments presented there show how well the method works. In this paper we use positive schemes to solve Riemann problems for two-dimensional gas dynamics.
Quantitative methods for evaluating hospital design. A stochastic model for interdepartment traffic. (1970)

A stochastic model is developed to describe the traffic among ten hospital departments or functional centers that generate 75 percent of all personnel trips to and from two nursing units with a total of 120 beds. The effects of five factors on travel frequencies are investigated by analysis of variance, as are the interactions among the factors. Multiple regression and correlation analyses are used to test the feasibility of predicting travel frequencies from the patient census in three levels of care and from the size of the nursing unit staff, which are found not to be very useful predictors. A Poisson distribution is found to be a good descriptor of the observed frequency distributions for seven of the ten departments studied.
Diagnosis and Management of Central Nervous System Metastases from Breast Cancer (2003)

The brain, cranial nerves, leptomeninges, spinal cord, and eye compose the central nervous system (CNS) and are at risk for the development of metastases from breast cancer. Such metastases are diagnosed on the basis of clinical suspicion and substantiated by neuroimaging, resection when indicated, and sampling of cerebrospinal fluid when leptomeningeal metastasis (LM) is suspected. Treatment is aimed at palliation of symptoms and preservation of neurologic function. Historically, conventional radiation therapy has been the mainstay of palliative treatment for brain, cranial nerve, spinal cord, and ocular metastases. However, additional treatment options for brain metastases have been brought about by technological advances in surgery to resect brain metastases, and stereotactic radiosurgery (SRS) to focally irradiate metastases, both of which have been substantiated by data from randomized trials. Ongoing research is aimed at refining criteria to select which patients with brain metastases should undergo surgery and SRS and how these focal therapies should be optimally integrated with whole-brain radiotherapy. Therapy for LM must carefully balance the potential risks and perceived benefits associated with CNS-directed therapies. Despite advances in neuroimaging, surgery, and radiation therapy, novel treatments are needed to improve the effectiveness of treatments for CNS metastases, especially LM, while reducing attendant neurotoxicity.
Physical Chemistry Research Articles Published in the Bulletin of the Korean Chemical Society: 2003-2007 (2008)

The physical chemistry (PC) articles published in the Bulletin of the Korean Chemical Society (BKCS) from 2003 to 2007 are surveyed, and in-depth content analysis was conducted to classify the PC articles into 12 topics used in The Journal of Physical Chemistry (JPC). The PC articles published in the Journal of the American Chemical Society (JACS) in 2007 are also surveyed. The extensive summary of all PC articles in BKCS for the last five years reveals the current trend of physical chemistry research in Korea. The comparison study with the JACS shows that the proportion of PC articles among all articles published in BKCS (16%) is slightly higher than that of JACS (11%), and the non-Korean authorship ratio of BKCS (12%) is very low compared with the non-US authorship of JACS (52%). From the comparison study with articles published in JPC in 2007, it is found that BKCS disseminates various topics of physical chemistry researches adequately. In particular, BKCS most frequently published PC articles in molecular structure and spectroscopy topics, whereas JPC published surface chemistry and nano-chemistry articles most frequently. It is concluded that BKCS should publish more articles to be a leading journal, and it is suggested that the SCI impact factor of BKCS must be increased by improving the electronic version of BKCS.
Physical properties of gasoline/alcohol automotive fuels (1979)

Non-petroleum derived alcohols are likely candidates for near-future use as alternative automotive fuels. Low molecular weight alcohols may be used alone or in combination with gasoline, but either usage presents its own unique set of advantages and disadvantages. This report addresses the physical property changes (both beneficial and detrimental) which occur when alcohols are added to gasoline as fuel extenders. The experimental data and discussion of results cover four physical property areas: water tolerance, vapor pressure, distillation characteristics, and octane quality. The alcohols include methanol, ethanol, n-propanol, i-butanol, and synthetic methyl fuel. Several additional alcohols were tested, but only as gasoline/methanol cosolvents. The major objective of the physical properties study was to determine the interdependency among the variables which are responsible for the significant property changes so that, where possible, gasoline/alcohol properties can be estimated from blend composition. Trends are also discussed in terms of the general influences of system variables.

The SLIT–ROBO pathway: a regulator of cell function with implications for the reproductive system (2010)

The secreted SLIT glycoproteins and their Roundabout (ROBO) receptors were originally identified as important axon guidance molecules. They function as a repulsive cue with an evolutionarily conserved role in preventing axons from migrating to inappropriate locations during the assembly of the nervous system. In addition the SLIT-ROBO interaction is involved in the regulation of cell migration, cell death and angiogenesis and, as such, has a pivotal role during the development of other tissues such as the lung, kidney, liver and breast. The cellular functions that the SLIT/ROBO pathway controls during tissue morphogenesis are processes that are dysregulated during cancer development. Therefore inactivation of certain SLITs and ROBOs is associated with advanced tumour formation and progression in disparate tissues. Recent research has indicated that the SLIT/ROBO pathway could also have important functions in the reproductive system. The fetal ovary expresses most members of the SLIT and ROBO families. The SLITs and ROBOs also appear to be regulated by steroid hormones and regulate physiological cell functions in adult reproductive tissues such as the ovary and endometrium. Furthermore several SLITs and ROBOs are aberrantly expressed during the development of ovarian, endometrial, cervical and prostate cancer. This review will examine the roles this pathway could have in the development, physiology and pathology of the reproductive system and highlight areas for future research that could further dissect the influence of the SLIT/ROBO pathway in reproduction.
THE EFFECT OF ABNORMAL CHROMOSOME 10 ON TRANSPOSITION OF MODULATOR FROM THE <i>R</i> LOCUS IN MAIZE (1972)

Transposition of the non-specific repressor element, Modulator, from the R locus on chromosome 10 in maize, is enhanced by coupling with the K10 segment at a distance of at least 35 map units from R. There is no detectable interaction in the repulsion phase. The K10 effect appears to be relatively greater in the earlier somatic cell generations during ear development. The transposition rate also is affected by the direction of crosses, being somewhat higher on the ears of F(1) plants which received the compound mutable R allele from the pollen parent. The significance of the behavior of Modulator and other instability phenomena of higher plants is discussed in relation to chromosome organization.

Analysis of differential gene expression in the kidney by differential cDNA screening, subtractive cloning, and mRNA differential display. (1995)

It is becoming increasingly evident that significant changes in gene expression occur during the course of disease progression in both genetic and nongenetic kidney diseases. Knowledge of the differentially expressed genes may yield information about the abnormal biochemical events that occur in the initiation and pathogenesis of these diseases. The purpose of this review is to provide an overview of some of the current approaches for identifying and analyzing differentially expressed genes. The power of these techniques lies in their their ability to detect differences in the levels of specific mRNAs in the diseased compared to the nondiseased kidney without prior knowledge of their identity. The three basic techniques considered are differential cDNA library screening, subtracted cDNA libraries, and PCR-based differential display. Emphasis is placed on cDNA library construction and differential screening. Also reviewed are the analysis of differentially expressed cDNAs by Southern and Northern blot hybridization, S1-protection, RT-PCR, DNA sequencing, and DNA sequence analysis.
Chiral Gating for Size- and Shape-Selective Asymmetric Catalysis (2019)

A poor or mediocre stereoselectivity is a key roadblock for a chiral catalyst to find practical adoptions. We report a facile method to create a tunable chiral space near a chiral catalyst to augment its selectivity. The space was created rationally through templated polymerization within cross-linked micelles, using readily available amino acid derivatives. It provided gated entrance of reactants to the catalyst, enabling a mediocre prolinamide to catalyze aldol condensation in water with excellent yields and ee, in a size- and shape-selective manner.

Processing and modeling of multi-walled carbon nanotube/styrene-butadiene-styrene (SBS) composites for force sensing (2009)

A novel stress-sensitive nanocomposite that can be used as flexible force sensors with tailored sensitivity was fabricated. The nanocomposite consists of MWNTs as conductive filler and SBS as polymer matrix. Some electrical and mechanical properties of MWNT/SBS films were measured. A typical percolation phenomenon was observed with the MWNT/SBS composites. The elastic modulus and Poisson's ratio of the composites with different MWNT concentration showed no statistically significant differences. In a low stress range, the resistance of the MWNT/SBS composite film decreased rapidly with stress increasing. A modified piezoresistivity model based on simplified GEME was then conducted to predict the resistance change of the nanocomposite film in low stress range.

5-HT2 Receptors (2004)

5-HT(2) receptors are G-protein coupled receptors that currently comprise three subtypes: 5-HT(2A), 5-HT(2B) and 5-HT(2C) receptors. The subtypes are related in their molecular structure, amino acid sequence and signaling properties. 5-HT(2A) and 5-HT(2C) receptors have a widespread distribution and function in the central nervous system. 5-HT(2A)and 5-HT(2C) receptor antagonism is a property of certain antipsychotic and antidepressant drugs. 5-HT(2B) receptors have a restricted expression in the central nervous system. They have an important role in embryogenesis and in the periphery. In this article, selected aspects of 5-HT(2) receptor research are reviewed for each subtype under three main headings : (i) genes, protein structure and receptor signaling; (ii) receptor localization with emphasis on the CNS and (iii) compounds. The general discussion reflects on the reasons for the limited success in the clinic of 5-HT(2) receptor subtype selective drugs.

Expression of interleukin 17 and IgE, and its significance in patients with bronchial asthma (2012)

To investigate the expression and its significance of interleutin-17 (IL-17) and immunoglobulin E (IgE) in patients with bronchial asthma, sixty adult patients with bronchial asthma and 30 healthy human control were sequentially enrolled in this study. The production of IL-17 was measured by enzyme-linked immunosorbent assay (ELISA) and fluorescent quantitative polymerase chain reaction (qPCR), respectively. The correlation between expression of IgE and IL-17 was analyzed. It was found that IL-17 was significantly up-regulated in bronchial asthma in comparison to the health control on mRNA level, and serum levels of IL-17 and IgE in bronchial asthma were significantly higher than those in health control, respectively (P < 0. 001). Significant positive correlation in bronchial asthma were found between expression of IL-17 and IgE (r = 0.7082, P = 0.0418). The present study implied that expressions of IL-17 and IgE play an important role in the development of bronchial asthma.   Key words: Bronchial asthma, immunoglobulin E, interleukin-17, enzyme-linked immunosorbent assay (ELISA).

Electronic-structure calculations are performed, within the local-density approximation to the density-functional theory, using the full-potential linear muffin-tin orbital method to understand the relation between structural and electronic properties of ${\mathrm{ReO}}_{3}$ , ${\mathrm{WO}}_{3}$ , and the stoichiometric tungsten bronze ${\mathrm{NaWO}}_{3}$ . Energy changes associated with small deformations from the cubic phase indicate that ${\mathrm{ReO}}_{3}$ and the tungsten bronze are stable when cubic while the W ion in ${\mathrm{WO}}_{3}$ shows a tendency to off-center displacements. The different behavior is explained by examining the band structure of the compounds. Calculated frequencies and eigenvectors of \ensuremath{\Gamma} phonons in ${\mathrm{ReO}}_{3}$ corroborate the existence of high-frequency modes in this crystal which supports a recent theoretical proposal for the interpretation of its electrical resistivity.
Long-acting beta2-agonists for stable chronic asthma (2003)

Long acting beta-2 agonists are effective in the control of chronic asthma, and the evidence supports their use in addition to inhaled corticosteroids, as emphasised in current guidelines. Further research is needed on their use in children under 12 and in mild asthmatics not taking ICS.
