Heparin-like activity in uterine fluid.

Field: Medicine (Health Sciences)

Uterine fluid was collected from a group of normal patients and a group of patients with menorrhagia. Heparin-like activity was detected in 34 out of 38 samples using an anti-Xa heparin assay. The heparin-like activity in uterine fluid was inhibited by adding the heparin antagonist hexadimethrine bromide to the assay. Concentrations of fibrinogen-fibrin degradation products (FDPs) were measured in five samples of uterine fluid. FDPs in the concentration detected had no effect on the anti-Xa assay. Heparin-like activity was higher in the group with menorrhagia, although the differences were not significant. Heparin-like activity increased throughout the menstrual cycle and decreased during menstruation, suggesting a possible cyclical variation in activity. There was no correlation between mast cell numbers in the endometrium and myometrium and heparin-like activity in uterine fluid and no correlation between the numbers and the stage in the menstrual cycle. In a few patients with intrauterine contraceptive devices (IUCDs) heparin-like activity was increased.
INFLUENCE OF INFORMATION TECHNOLOGY ON FORMING OF LOGICAL CULTURE OF THE FUTURE FOREIGN LANGUAGES TEACHERS

Field: Social Sciences (Social Sciences)

The “logical culture” phenomenon that is considered as a required component of practical training for the future foreign languages teachers is defined in the article; the influence of information technologies on the process of logical culture formation is studied as well. The levels of logical culture formation of future foreign languages teachers are specified as well as logical culture components are described for each level. It has been found that the rate of logical culture competence can be improved by implementation of educational information technologies.
A novel low-complex and low-memory method for accurate single-tone frequency estimation

Field: Computer Science (Physical Sciences)

In this paper a new method for accurate frequency estimation of a single sinusoid is described. The main feature of the proposed method, mainly based on a simple digital non-linear filter, is its intrinsic low complexity development and use. The method, in fact, needs about 2N s arithmetic operations, where N s is the number of samples, and has very small memory requirements even when high accuracy is needed. Furthermore, we show that in case of moderate and high signal to noise ratio levels, the method is able to reach the Cramer-Rao Lower Bound (CRLB) but at a lower implementation cost.
Sym plasmid transfer to various symbiotic mutants of Rhizobium trifolii, R. leguminosarum, and R. meliloti

Field: Agricultural and Biological Sciences (Life Sciences)

Two self-transmissible Sym(biosis) plasmids, one encoding pea-specific nodulation and nitrogen-fixation functions (plasmid pJB5JI) and the other encoding clover-specific nodulation and nitrogen-fixation functions (plasmid pBR1AN) were used to determine whether the symbiotic genes encoded on these plasmids are expressed in various members of the Rhizobiaceae. The host specificity of Rhizobium trifolii and R. leguminosarum Sym plasmid-cured strains could be directly determined by the transfer to these strains of the appropriate Sym plasmid. The nodulation of white clovers was restored by either plasmid pJB5JI or pBR1AN when these plasmids were transferred to two transposon Tn5-induced hair-curling (Hac-) R. trifolii mutants. In addition, lucerne nodulation was restored to a Hac- R. meliloti mutant when either plasmid pBR1AN or pJB5JI was transferred to this strain. The phenotype of nonmucoid (Muc-) Rhizobium mutants, which had altered cell surfaces, was not influenced by the transfer to these strains of plasmid pBR1AN or plasmid pJB5JI.
Nexus between the Exchange Rate Spill-Over Movement and Macroeconomic Variables in South Asian Countries

Field: Economics, Econometrics and Finance (Social Sciences)

The objective of this study was to examine the relationship between the Exchange Rate spill-over and Macro Economic Determinants in selected South Asian Countries (Afghanistan, India and Pakistan). The study employed 10 years of data from 2011 to 2021 of macroeconomic variables such as TIN- Total Investment, INF - Inflation, IMP - Imports, EXP - Exports, GTE - Government Total Expenditure, GNL - Government Net Lending, ER – Exchange Rate. The result evidenced that selected macroeconomic variables changes doesn’t have any connection in the changes of ER of India, Pakistan and Afghanistan. The ER changes are highly autocorrelated and act highly independence in the last ten years. Moreover, the depreciation of currency values replicates economic instability and drastically straight fall. Asian countries operating their currency based on a managed floating ER regime. It’s marking a market-determined ER regime of the currency with provision for timely intervention by the central bank. Managed float regime is an international financial environment in which ERs fluctuates from day to day, but central banks attempt to influence their countries’ ERs by buying and selling currencies to maintain a certain range. This study would be useful to the retail investors to speculate and arbitrage and (economic policy) policymakers to monitor, Forecasting and Simulation the ER movements.
Mental health and addictions: renewed hope for better care.

Field: Health Professions (Health Sciences)

Examination of the care needs of individuals suffering from mental illness and addictions shows that as many as 75% of the people who need care receive none at all (Ontario Ministry of Health, 1990). Further, about 20% of the general population in Canada are afflicted with mental illness or addiction in any given year, and 3% have severe and persistent disablement (McEwan & Goldner, 2000; Offord et al., 1996). This figure is even higher amongst those in diverse ethno-cultural communities who face not only high levels of stigma but also language and other cultural barriers (Garfinkel, 2002).
In terms of addictions, there are many devastating effects. One in 10 adults reports problems with drinking, and in 1995 more than 6,500 Canadians died as a result of alcohol use, while over 80,000 were hospitalized for alcohol-related health problems (Canadian Centre on Substance Abuse [CCSA], 1999). The health-care cost of alcohol in Canada is 2.7% of GDP, 30% to 90% of people receiving alcohol/drug services have a concurrent disorder, and 65% of people receiving mental health services have a concurrent disorder (Murthy, 2001).1
A condition monitoring approach for the detection of defects in the primary suspension of railway vehicles

Field: Engineering (Physical Sciences)

This work presents the main problems in the primary suspension of metro vehicles and a methodology to detect those using wayside systems. The primary suspension is usually based on rubber elements, which are space saving and have damping properties. However, rubber characteristics change with time, often in a different way in each element. Differences between elements can cause irregular transmission of loads to the wheels, and thus, a reduction or loss of guidance forces. The ageing of rubber can also lead to a general stiffening of the primary suspension, which increases the risk of derailment. This paper presents a wayside system that uses a few strain gauge bridges to detect those problems independently of the vehicle load and speed. Firstly, the system is developed by means of a multibody model. Secondly, a demonstrator is installed in an operating metro exploitation. Finally, the accuracy of the predictions is proven by testing some of the elements in the laboratory.
Identification, Localization, and Characterization of Hematopoietic Stem Cells and Their Niche.

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

To improve our ability to identify HSCs and their localization in vivo we compared the gene expression profiles of highly purified hematopoietic stem cells (HSCs) and non-self-renewing multipotent progenitors (MPPs). Cell surface receptors of the SLAM family, including CD150 and CD48, were differentially expressed among functionally distinct progenitors such that HSCs were highly purified as CD150+CD48- cells whereas MPPs were CD150-CD48-. The ability to purify HSCs based on a simple combination of SLAM receptors allowed us to identify HSCs in tissue sections. Most HSCs were associated with sinusoidal endothelium in the spleen and bone marrow. This raised the possibility that HSCs reside in perivascular niches. Our data suggesting that HSCs reside perivascularly was in contrast to studies which proposed that HSCs identified by the thymidine analogue bromo-deoxyuridine (BrdU)-label retention are associated with osteoblasts via N-cadherin-mediated homophilic adhesion. We therefore tested the hypotheses that N-cadherin was important for HSC maintenance and that HSCs could be identified by BrdU-label retention. We did not detect N-cadherin expression in HSCs by polymerase chain reaction, using anti-N-cadherin antibodies, or by ß-galactosidase staining of N-cadherin gene-trap mice. Moreover, N-cadherin deficiency did not affect bone marrow cellularity, the numbers of colony-forming progenitors, the frequency of HSCs, the ability of HSCs to sustain hematopoiesis over time, or their ability to reconstitute irradiated mice. These results indicate that HSCs do not depend on N-cadherin-mediated adhesion to osteoblasts for their maintenance. We tested whether HSCs might retain BrdU, either because they segregate chromosomes asymmetrically or because they divide slowly, by administering BrdU to newborn, cyclophosphamide/G-CSF mobilized, and normal adult mice for 4 to 10 days, followed by 70-days without BrdU. In each case, less than 6% of HSCs retained BrdU and less than 0.5% of BrdU-retaining hematopoietic cells were HSCs, revealing poor specificity and poor sensitivity as an HSC marker. Sequential administration of chloro-deoxyuridine (CldU) and iodo-deoxyuridine (IdU) suggested that all HSCs segregate their chromosomes randomly. Division of individual HSCs in culture revealed no asymmetric segregation of label. HSCs therefore cannot be identified based on BrdU label-retention and BrdU-label retaining cells are highly unlikely to be HSCs.
(Au@perylene-crystal)@pani triple-layer nanocomposite via colloid synthesis.

Field: Chemistry (Physical Sciences)

Current progress in nanocomposites frontiers have incites innovative discoveries in both directions of applicable working models and comprehensive investigation of properties. Many studies emphasize on nanocomposites based organic material incorporated on metal substrate. Such nanocomposites are of interest due to tunable optoelectronic properties by their molecular arrangement. Up to now, however, synthesize of organic crystal on metal substrate are limited only to top-down methods. These techniques produce organic crystals that are immobile on metal substrate and thus laborious to further exploit. Here, we developed the first fabrication of (Au@Perylene-crystal)@PANI triple-layer structure via colloid synthesis. Through self-assembly, facile bottom-up manufactures of nanocomposites as building block was adeptly possible. Intermediate structures were observed by TEM and crystal growth mechanism was proposed based on Quasi Epitaxial Theory. Diverse application for triple-layer was demonstrated in simple drug delivery model.

저전압(~1 ㎸)에서 구동되어 수 ㎁의 전류를 얻을 수 있는 초소형 전자 칼럼(microcolumn) 설계를 위한 프로브(probe) 빔의 직경이 최소가 되는 전자 광학계의 조건을 조사하였다. 프로브 빔의 최소 직경은 전자 방출원의 특성에 의존하는데, 동일 조건의 광학계에 대하여 thermal field emitter(TFE)인 경우 ~20 ㎚인 반면 cold field emitter(CFE)인 경우 ~10 ㎚인 것으로 조사되었다. We examine the adjustment of the semiconvergent angle and current for the miniaturized micro column working at low voltage but producing maximized current. Our study shows that the minimum electron beam sizes are 10 ㎚ for the cold field emitter (CFE) and 20 ㎚ for the thermal field emitter (TFE) at a given condition.

Arguing about religion: BBC World Service Internet forums as sites of postcolonial encounter

Field: Social Sciences (Social Sciences)

This paper compares the content, context and facilitation of discussions about religion and politics on contrasting types of Internet forum in English and Arabic, comparing forums linked to the current affairs output of the BBC World Service (BBCWS), Al-Jazeera and Al-Arabiyya between 2007 and 2010. It examines how these forums are structured by a range of technological and political factors, reflecting the postcolonial context of encounter. It demonstrates that the consequences of deploying these technologies in this context are ambivalent. On the one hand, they enable participation in discussion in contexts where political debate is restricted, allow conversation between individuals that would be impossible in embodied form, and strengthen diasporic connectivity. On the other, they are used behind a rhetoric of free speech which masks exclusionary power relations. Comparison between types of BBC forum further demonstrates the importance of how new technologies are deployed for forms of communication and community construction.
The Regulation of Astrocytic Glutamate Transporters in Health and Neurodegenerative Diseases

Field: Neuroscience (Life Sciences)

The astrocytic glutamate transporters excitatory amino acid transporters 1 and 2 (EAAT1 and EAAT2) play a key role in nervous system function to maintain extracellular glutamate levels at low levels. In physiology, this is essential for the rapid uptake of synaptically released glutamate, maintaining the temporal fidelity of synaptic transmission. However, EAAT1/2 hypo-expression or hypo-function are implicated in several disorders, including epilepsy and neurodegenerative diseases, as well as being observed naturally with aging. This not only disrupts synaptic information transmission, but in extremis leads to extracellular glutamate accumulation and excitotoxicity. A key facet of EAAT1/2 expression in astrocytes is a requirement for signals from other brain cell types in order to maintain their expression. Recent evidence has shown a prominent role for contact-dependent neuron-to-astrocyte and/or endothelial cell-to-astrocyte Notch signalling for inducing and maintaining the expression of these astrocytic glutamate transporters. The relevance of this non-cell-autonomous dependence to age- and neurodegenerative disease-associated decline in astrocytic EAAT expression is discussed, plus the implications for disease progression and putative therapeutic strategies.
Fossilized Metazoan Embryos from the Earliest Cambrian

Field: Earth and Planetary Sciences (Physical Sciences)

Small globular fossils known as Olivooides and Markuelia from basal Cambrian rocks in China and Siberia, respectively, contain directly developing embryos of metazoans. Fossilization is due to early diagenetic phosphatization. A nearly full developmental sequence of Olivooides can be observed, from late embryonic stages still within an egg membrane, to hatched specimens belonging to several ontogenetic stages. Earlier cleavage stages also occur, but cannot be identified to taxon. Olivooides shows similarities to coronate scyphozoans and to their probable Paleozoic representatives, the conulariids. Markuelia eggs contain looped embryos of a segmented worm with short, conical processes covering the body.

Feast Of Souls: Indians And Spaniards In The Seventeenth-Century Missions Of Florida And New Mexico

Field: Social Sciences (Social Sciences)

During the seventeenth century, Spanish conquerors established Franciscan missions among the native inhabitants of Florida and New Mexico. The missionaries in the northern frontier doctrinas of Spain's New World empire adapted methods tested in Iberia and Central and South America to conditions among the Guales, Timucuas, Apalaches, and the various Pueblo peoples. The mission Indians of Florida and New Mexico responded to conquest and conversion in myriad ways. They incorporated Spaniards in traditional ways, they attempted to repel the interlopers, they joined the newcomers and accepted novel modes of behavior, they discriminated between which foreign concepts to adopt and which to reject, and they avoided entangling relations with the Spaniards as best they could. By the end of the seventeenth century the frontier missions of Florida and New Mexico collapsed under the weight of violent struggles among Indians, Spanish officials, Franciscan missionaries, and outside invaders. This comparative study will reveal patterns in Spanish frontier colonization and Indian responses to Spanish conquest and missions.
[Methods for detecting plasmid-borne colistin resistance mediated by the mcr genes].

Field: Immunology and Microbiology (Life Sciences)

Prospective prevalence studies of intestinal carriage of colistin-resistant Enterobacterales among Czech hospitalized patients and travelers do not yet indicate the spread of strains with mcr-mediated plasmid-borne colistin resistance. However, the high prevalence of strains carrying the mcr genes in raw meat products poses a risk of exposure for their consumers. The detection of mcr-harbouring colistin-resistant strains cannot be expected during routine microbiological testing, without using reliable but expensive methods. A suitable alternative method for active monitoring of colistin resistance is the use of selective agar media with colistin followed by verification of the resistance in the obtained isolates.

The dimidiate pixel model was used to calculate vegetation coverage. The distribution pattern, dynamic changes and terrain differentiation of vegetation coverage were detected in temperate continental semi-arid monsoon climate zone from 2000 to 2017. The results showed that: (1) during the study period, the functional planning of the study area was changed from economic development to national nature reserve. With the change, vegetation coverage decreased and then increased, tending well overall. The average area of 64.19% was dominated by medium-high vegetation coverage. (2) The spatial pattern of vegetation coverage was generally characterized by the distribution of "high east and low west, south high and low north". The mid-high vegetation coverage was concentrated in the southern part of Hohhot section and Wulanchabu section of Daqing Mountain, while the low vegetation coverage was mainly distributed in the western section of the mountain. (3) During the study period, 32.46% of vegetation coverage in the study area was improved and 12.92% of vegetation was degraded, indicating that the vegetation coverage in the study area improved overall. (4) The topographic factor had a significant impact on the vegetation coverage distribution pattern in the study area. Vegetation coverage increased with altitude, and was the highest in the 2000-2296 m elevation. Vegetation coverage was positively correlated with slope, and the higher the slope, the greater the vegetation cover. Vegetation coverage was significantly different in different slope directions. The overall vegetation coverage shows the distribution that shady slope is larger than flat land and flat land is larger than sunny slope. 参考文献 相似文献 引证文献
