World Journal of Gastrointestinal Surgery 2017年第2期9卷 53-60页

AIM To assess nutritional recovery,particularly regarding feeding jejunostomy tube(FJT)utilization,following upper gastrointestinal resection for malignancy. MeTHODS A retrospective review was performed of a prospectively-maintained database of adult patients who underwent esophagectomy or gastrectomy(subtotal or total)for cancer with curative intent,from January 2001 to June 2014. Patient demographics,the approach to esophagectomy,the extent of gastrectomy,FJT placement and utilization at discharge,administration of parenteral nutrition(PN),and complications were evaluated. All patients were followed for at least ninety days or until *** The 287 patients underwent upper GI resection,comprised of 182 esophagectomy(n=107 transhiatal,58.7%; n=56 Ivor-Lewis,30.7%)and 105 gastrectomy [n=63 subtotal(SG),60.0%; n=42 total(TG),40.0%]. 181 of 182 esophagectomy patients underwent FJT,compared with 47 of 105 gastrectomy patients(99.5% vs 44.8%,P ergone TG(n=39,92.9% vs n=8 SG,12.9%,P edian length of stay was similar between esophagectomy and gastrectomy groups(14.7 d vs 17.1 d,P=0.076). Upon discharge,87 esophagectomy patients(48.1%)were taking enteral feeds,with 53(29.3%)fully and 34(18.8%)partially dependent. Meanwhile,20 of 39 TG patients(51.3%)were either fully(n=3,7.7%)or partially(n=17,43.6%)dependent on tube feeds,compared with 5 of 8 SG patients(10.6%),all of whom were partially dependent. Gastrectomy patients were significantly less likely to be fully dependent on tube feeds at discharge compared to esophagectomy patients(6.4% vs 29.3%,P=0.0006). PN was administered despite FJT placement more often following gastrectomy than esophagectomy(n=11,23.4% vs n=7,3.9%,P=0.0001). FJT-specific complications requiring reoperation within 30 d of resection occurred more commonly in the gastrectomy group(n=6),all after TG,compared to 1 esophagectomy patient(12.8% vs 0.6%,P=0.0003). Six of 7 patients(85.7%)who experienced tube-re

Observations on the efficacy of Various Forms of Selenium for Livestock: A Review

引用

Biomedical and environmental Sciences 1997年第2期10卷 280-291页

作者： J. e. OLDFIeLD (Department or Animal Science, Oregon State University,Corvallis, OR 97331, USA) Department of Animal Science Oregon State University Corvallis 97331 USA.

Since 1957, selenium has found extensive use in livestock production to maintain an adequate selenium status in animals in areas of soil and feed/forage deficiency. Selenium may be given directly to livestock, or applied as a fertilizer amendment to increase selenium content of their feeds. This paper addresses the area of direct supplementation, which includes oral and parenteral supplementation, and with ruminant animals the use of slow-release boluses. Various chemical forms of selenium have been examined as supplemental sources, with sodium selenite being the earliest compound of choice. Comnbination of selenium supplementation with other livestock managernent practices led to use of selenium dioxide, which avoided solubility problems with selenite but produced effective responses. Barium salts have been used with some success as supplemental selenium sources. experience with ruminal boluses has shown that high pressure pelleting of increased grain size selenium, in hollow pellets, has prolonged their useful life. Attention has been paid recently to residual selenium returned to the soil from livestock supplementation practices and the resulting opinion is that currently approved practices are acceptable from the point of view of environmental quality

The anti-correlation method for removing harmonic distortion in vibroseis slip-sweep data

Applied Geophysics 2012年第2期9卷 159-167,234页

The slip-sweep technique is one of the high-efficiency, high-fidelity, and environmental vibroseis seismic prospecting techniques which consists of a vibrator group sweeping without waiting for the previous group＇s sweep to terminate. The cycle time can be reduced drastically and hence the production efficiency can be increased significantly but harmonic distortion of one sweep will leak into the record of the other sweep. In this paper, we propose an anti-correlation method for removing harmonic distortion in vibroseis data. This method is based on decomposition of the ground force signal into fundamental and harmonic components. Then the corresponding anti-correlation operator can be computed to estimate the energy of each harmonic after correlating the vibroseis data with the corresponding harmonic component. Finally, the vibroseis harmonic noise to be removed can be obtained by subtracting the extracted harmonic noise from the traces of the previous group＇s sweep. The advantage of the proposed method is that it can process both uncorrelated and correlated vibroseis seismic data. Moreover, the algorithm is simple, stable, and computationally fast. especially, the significant contribution of this method is a considerable reduction in the harmonic without any alteration of the desired signals. The method was tested on both synthetic and field data sets to validate the good harmonic noise suppression results.

Coretop sediment samples covering water depth from 247 to 1474 m in the Northwestern Indian Ocean were analyzed. 6 species of Uvigerina among 77 species and 11 species-complexes were found in all 26 samples. They are Uvigerina auberiana d’Orbigny, Uvigerina hispida Schwa-ger, Uvigerina peregrina Cushman, Uvigerina proboscidea Schwager, Uvigerina spinicostata Cushman and Jarvis, and Uvigerina sp. Characteristics of Uvigerina are (1) high abundance due to rich food supply and less competitors; (2) low diversity because only those eurytopic / opportunistic forms can survive environment of low dissolved oxygen value; (3) various test shapes and ornamentations which are controlled by respiration or gas exchange of the cell; and (4) abundance of Uvigerina is well related with environmental factors such as water depth, oxygen content and productivityor food supply. These Uvigerina species can be used as pa-leo-environmental proxy of low oxygen and rich organic matter supply related to high-surface

In this paper the concept of positive definite bilinear matrix moment functional. acting on the space of all the matrix valued continuous functions defined on a bounded interval [a,b], is introduced. The best approximation matrix problem with respect to such a functional is solved in terms of matrix Fourier series. Basic properties of matrix Fourier series such as the Kiemann -Lebesgue matrix property and the bessel-parseval matrix inequality are proved. The concept of total set vjith respect to a positive definite matrix functional is introduced , and the totallity of an orthonormal sequence of matrix polynomials with respect to the functional, is established.
