Coprophagy in Laboratory Animals: A Preliminary Study To Assess Potential Influences of Excreta Ingestion on Radionuclide Retention Patterns (1974)

Abstract Rats were gavaged with 144CeCI3 and either prevented from or allowed to practice coprophagy. Whole-body retention data varied widely and, in some instances, resulted in highly erratic patterns and enhanced gastrointestinal tract absorption of gavaged 144Ce in copraphagy-allowed rats. Greater whole-body retention of 144Ce was observed in coprophagy-allowed animals kept in solid plastic shoe box-type cages than in those kept in wire-bottom cages, owing to their continued access to the radioactive feces excreted within the first days after 144Ce gavage. Potential influences of coprophagy on results of experiments involving toxic materials are discussed.
Synthesis and bioconjugation of CdSe/CdS core/shell nanoparticles to poly(ethylene glycol) analogues (2005)

CdSe core nanoparticles were synthesized from the stearate complex of Cd and Se powder in octadecene solution containing organic stabilizers. After purification, CdS inorganic shell was made on CdSe core to yield CdSe/CdS core/shell nanostructure using successive ion layer adsorption and reaction method. The outmost half layer of the inorganic CdS shell was designed to be cadmium ion layer. Then, the hydrophobic CdSe/CdS was converted to hydrophilic CdSe/CdS-AET by treating with aminoethanethiol (AET). The cadmium half layer on CdSe/CdS surface was an excellent promoter for the covalent conjugation of CdSe/CdS to thiolate of AET. Finally, CdSe/CdS-AET was bioconjugated to a PEG analogue, poly(ethylene glycol) monomethyl ether mono(succinimidyl succinate) ester. The advantage of using AET compared to mercaptopropionic acid was the stabilization of Cd-thiolate bond during the following bioconjugation process. Investigations of semiconductor nanoparticles with different surface materials are discussed using transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis), photoluminescence (PL), and Fourier transformed-infrared (FT-IR) spectroscopy.

Nonisothermal Effects During Injection and Falloff Tests (1986)

Summary Numerically simulated pressure transients during injection and falloff tests are analyzed to develop methods for obtaining the correct permeability/thickness of the reservoir and the skin factor for the well. The results show that to analyze correctly the pressure transients governed by a moving thermal front, the fluid-property values must correspond to the temperature of the injected fluid. For pressure falloff tests and for injection tests conducted in a well cooled by previous injection or drilling, however, the physical properties of the in-situ reservoir fluids must be used. The application of conventional isothermal methods for calculating skin values from injection and falloff data will give erroneous results. A new method is presented for calculating skin values from injection and falloff data that accurately corrects for nonisothermal effects. Examples are given to illustrate this analysis method. The technique is applied to the analysis of injection test data from a well located in the East Mesa geothermal field in southern California.
Current biodiversity and hotspots in the primeval beech forest – Poloniny National Park, the Eastern Carpathians (Slovakia) (2018)

The research was carried out in the territory of the Bukovske vrchy hills, where natural beech forest stands contain an invaluable genetic reservoir of European beech and other species associated and dependent on these forest habitats. Present study is focused on the creation of local biodiversity hotspots. The structure of local biodiversity valuable areas is based on spatial distribution of indicator species of primeval beech forests and species of conservation interest. Field data on rare bryophytes, vascular plants, macrozoobentos and vertebrates were condensed into GIS layers. The new zonation of the Poloniny National Park was suggested. Spatial distribution of relevant species should be included in the new zonation which we believe will better ensure the protection of beech forests.

Computed tomography of lethal midline granuloma (1991)

In order to clarify the CT findings of lethal midline granuloma(LMG) diagnosed clinically or histopathologically, the authors retrospectively analyzed 12 patients who were ween at Kyungpook National University Hospital from February 1985 to August 1989. CT showed nasal mucosal thickening and/or soft tissue mass( 9 cases), spreading of the lesions along the facial subcutaneous fat plane(8 cases), invasion into the paranasal sinuses(5 cases), bone destruction(5 cases) nasopharyngeal mass lesion(2 cases), and extension of the lesion into the infratemporal fossa(1 case). In spite of the fact that CT does not make definitive diagnosis of LMG, it permits evaluation of the extent of the lesion, detection of the combined lesion, differential diagnosis, and close monitoring of its evolution under treatment.
Improving web information indexing and retrieval based on center block duplication detection (2008)

Duplicated information in today's Web has serious negative impact to Web search engines in that it increases the size of the index and results in low efficiency for Web information retrieval. One important fact is that a large amount of Web content duplication happens at block level in addition to site and page level due to various reasons. Besides, when searching through the Web, in most cases the desired information is located at the center block of a relevant page. Based on these two observations, we propose an efficient block level duplication detection algorithm based on resemblance transitivity, and index center blocks instead of entire Web pages for Web information retrieval. Experiments show that these strategies can effectively reduce index size and index construction time without sacrificing the effectiveness of Web information retrieval.
Differential Sensitivity of Epithelial Cells to Extracellular Matrix in Polarity Establishment (2014)

Establishment of apical-basal polarity is crucial for epithelial sheets that form a compartment in the body, which function to maintain the environment in the compartment. Effects of impaired polarization are easily observed in three-dimensional (3-D) culture systems rather than in two-dimensional (2-D) culture systems. Although the mechanisms for establishing the polarity are not completely understood, signals from the extracellular matrix (ECM) are considered to be essential for determining the basal side and eventually generating polarity in the epithelial cells. To elucidate the common features and differences in polarity establishment among various epithelial cells, we analyzed the formation of epithelial apical-basal polarity using three cell lines of different origin: MDCK II cells (dog renal tubules), EpH4 cells (mouse mammary gland), and R2/7 cells (human colon) expressing wild-type α-catenin (R2/7 α-Cate cells). These cells showed clear apical-basal polarity in 2-D cultures. In 3-D cultures, however, each cell line displayed different responses to the same ECM. In MDCK II cells, spheroids with a single lumen formed in both Matrigel and collagen gel. In R2/7 α-Cate cells, spheroids showed similar apical-basal polarity as that seen in MDCK II cells, but had multiple lumens. In EpH4 cells, the spheroids displayed an apical-basal polarity that was opposite to that seen in the other two cell types in both ECM gels, at least during the culture period. On the other hand, the three cell lines showed the same apical-basal polarity both in 2-D cultures and in 3-D cultures using the hanging drop method. The three lines also had similar cellular responses to ECM secreted by the cells themselves. Therefore, appropriate culture conditions should be carefully determined in advance when using various epithelial cells to analyze cell polarity or 3-D morphogenesis.
Application of inductively coupled plasma mass spectrometry to the simultaneous determination of chlorine, bromine and iodine in the National Bureau of Standards Standard Reference Material 1648 Urban Particulate (1988)

The application of inductively coupled plasma mass spectrometry (ICP-MS) to the simultaneous determination of chlorine, bromine and iodine in the National Bureau of Standards (NBS) Standard Reference Material (SRM) 1648 Urban Particulate is described. The potential of ICP-MS for simultaneous multi-element trace determinations after a conventional dissolution procedure is illustrated. Various possible methods for including the halides are considered, and various sample dissolution procedures are investigated. Data presented for the NBS SRM 1648 Urban Particulate are considered in terms of the previously published results and polyatomic ion interferences from sample fusion procedures. It has been shown that the method has great potential for the determination of total chlorine, bromine and iodine in environmental dust and other samples.
Economic Thought and Culture in Revolutionary Mexico: Carlos Diaz Dufoo's Critique of the Humboldtian Idea of Mexico's Legendary Wealth (2006)

México y los capitales extranjeros (1918), del economista Carlos Díaz Dufoo, fue la primera crítica integral de la "riqueza secundaria de México", la noción tradicional de que México contenía inmensas riquezas debido a su tamaño Jorge, su clima variado y su valiosa riqueza natural. recursos, popularizado por el Ensayo Político sobre el reino de la Nueva España de la época de la independencia de Alexander von Humboldt. El ataque de Díaz Dufoos tuvo sus raíces en una noción contemporánea de riqueza que influyó en sus percepciones de la economía mexicana. Pero su polémico texto también estaba enredado en una política revolucionaria. Por lo tanto, al examinar el asalto de Díaz Dufoo a la leyenda y la recepción de los revolucionarios de su controvertida crítica, este ensayo proporciona información sobre las ideas económicas y los vínculos entre la ideología económica y la política política en el México revolucionario.
Ribavirin Therapy for Nipah Virus Infection (2004)

The January 2004 issue of the Journal of Virology contains a very interesting paper on protection of mice against lethal challenge with Nipah virus by vaccination and by passive transfer of antibody (2). However, in the Discussion the authors (referring to the Nipah virus epidemic which affected Malaysia in 1998) state that “ribavirin was tried on some patients but with no significant results.” This statement is misleading and not supported by the two references cited (1, 3). One of these references refers to a review article that I wrote in 2001; the only mention of Nipah virus in this paper is a speculative statement that ribavirin might prove of value in the treatment of Nipah virus infection, based solely on the known activity of this agent against other paramyxoviruses (3). The other paper cited (1) reported an open-label study of ribavirin in 140 patients with Nipah virus encephalitis, using as controls 54 similar patients who were managed before ribavirin became available or who refused treatment. Mortality in the ribavirin-treated limb was 32%, compared with 54% in the controls (P = 0.011). Duration of ventilation and total hospital stay were both significantly shorter in the ribavirin group (P = 0.0002 and <0.0001, respectively). There was a nonsignificant trend to a reduction in neurological deficits in survivors who received ribavirin (P = 0.17).

There is certainly a paucity of blinded, randomized, controlled trial data on the efficacy of ribavirin in this condition, but it is clearly quite incorrect, on the basis of the references cited, to say that ribavirin was ineffective, and it would be a pity if potential researchers who read this article were deterred from studying the effects of ribavirin more thoroughly.
Establishment and characterization of chromosomal aberrations in human cholangiocarcinoma cell lines by cross-species color banding (2000)

Cholangiocarcinoma (CC), a malignant neoplasm of the biliary epithelium, is usually fatal because of difficulty in early diagnosis and lack of availability of effective therapy. Furthermore, little is known about the genetics and biology of CC. Only a few reports concerning cytogenetic studies of CC have been published, and few cell lines have been established. We recently established four CC cell lines, designated as SCK, JCK, Cho-CK, and Choi-CK, and report the first application of cross-species color banding (RxFISH) and multiple chromosome painting for the characterization of the chromosomal rearrangements of these CC cell lines. Each cell line had unique modal karyotypic characteristics and showed a variable number of numerical and structural clonal cytogenetic aberrations. Chromosomes 3, 6, 7, 8, 12, 14, 17, and 18 were commonly involved in structural abnormalities. Homogeneously staining regions were determined in SCK and JCK, and double minute chromosomes were found in Cho-CK. The chromosomal aberrations of the four CC cell lines were effectively analyzed by RxFISH and FISH with multiple chromosome painting probes. The nonrandom rearrangements suggest candidate regions for isolation of genes related to CC.

Life and Death: Metabolic Rate, Membrane Composition, and Life Span of Animals (2007)

Maximum life span differences among animal species exceed life span variation achieved by experimental manipulation by orders of magnitude. The differences in the characteristic maximum life span of species was initially proposed to be due to variation in mass-specific rate of metabolism. This is called the rate-of-living theory of aging and lies at the base of the oxidative-stress theory of aging, currently the most generally accepted explanation of aging. However, the rate-of-living theory of aging while helpful is not completely adequate in explaining the maximum life span. Recently, it has been discovered that the fatty acid composition of cell membranes varies systematically between species, and this underlies the variation in their metabolic rate. When combined with the fact that 1) the products of lipid peroxidation are powerful reactive molecular species, and 2) that fatty acids differ dramatically in their susceptibility to peroxidation, membrane fatty acid composition provides a mechanistic explanation of the variation in maximum life span among animal species. When the connection between metabolic rate and life span was first proposed a century ago, it was not known that membrane composition varies between species. Many of the exceptions to the rate-of-living theory appear explicable when the particular membrane fatty acid composition is considered for each case. Here we review the links between metabolic rate and maximum life span of mammals and birds as well as the linking role of membrane fatty acid composition in determining the maximum life span. The more limited information for ectothermic animals and treatments that extend life span (e.g., caloric restriction) are also reviewed.
Backhaul-aware scheduling for WiMAX femtocell with limited backhaul capacity (2011)

A femtocell is designed to use a shared broadband IP link. A bottleneck may be occurred due to the limitation of provisioned bandwidth and the existence of background traffic especially in access network. The bottleneck will certainly affect the service performance of the femtocell access point (FAP), which would influence end user experience. In order to maintain QoS requirement against backhaul quality fluctuation, a FAP should be equipped with a QoS management capability which is aware of backhaul condition. By applying backhaul aware admission control and scheduling, FAP can determine whether or not the backhaul bandwidth capacity is able to support a new service session. FAP will know the backhaul bandwidth by implementing bandwidth estimation. When the congestion occurred, FAP will maintain the existing flows and accept sessions with higher priority services (i.e realtime) over lower priority traffic (ie. non-realtime), based on load demand of each service flows.
A high-performance lithium-ion battery anode based on the core–shell heterostructure of silicon-coated vertically aligned carbon nanofibers (2012)

This study reports a high-performance hybrid lithium-ion anode material using coaxially coated silicon shells on vertically aligned carbon nanofiber (VACNF) cores. The unique “cup-stacking” graphitic microstructure makes VACNFs a good lithium-ion intercalation medium and, more importantly, a robust bush-like conductive core to effectively connect high-capacity silicon shells for lithium-ion storage. The vertical core–shell nanowires remain well separated from each other even after coating with bulk quantities of silicon (equivalent to 1.5 μm thick solid films). This open structure allows the silicon shells to freely expand/contract in the radial direction during lithium-ion insertion/extraction. A high specific capacity of 3000–3650 mA h (gSi)−1, comparable to the maximum value of amorphous silicon, has been achieved. About 89% of the capacity is retained after 100 charge–discharge cycles at the C/1 rate. After long cycling, the electrode material becomes even more stable, showing the invariant lithium-ion storage capacity as the charge–discharge rate is increased by 20 times from C/10 to C/0.5 (or 2C). The ability to obtain high capacity at significantly improved power rates while maintaining the extraordinary cycle stability demonstrates that this novel structure could be a promising anode material for high-performance lithium-ion batteries.
SIM card based e-cash applications in the mobile communication system using OTA and STK technology (2006)

In the coming era of e-commerce and m-commerce, the payment becomes one of concerns for both customers and vendors. Various payment systems have been proposed for this manner. The electronic payment schemes, e-cheque and e-cash, are the most popular ways. The SIM cards for mobile handset provide the capacity of authentication, memorization and development so as to be used for e-cash applications. In this paper, we implement the e-cash over the air (OTA) and tool kit (STK) technology to establish the flows of including the function of e-remission, e-ATM, e-payment, and e-account-transferring.
