Most scientific attention on port studies centers on deep sea ports, especially container ports. In this paper, in contrast, attention is focused on the spatial–temporal development of inland waterway ports on the Midstream Yangtze River from 2001 to 2013. The aim of this study is to assess two relevant and complementary questions of the hinterland evolution: its geographical extent and the coordination relationship with the inland port. To conduct the study, it was necessary to first identify the boundaries of the ports' hinterlands within the given timeframe. Then, the coupling coordination degree model was introduced to explore the underlying relationship between the port service and hinterland economy. Furthermore, to better depict the intricate economic characteristics of the hinterland, the development stage theory was applied in the models. The results highlight the emergence of a discontinuous hinterland at Wuhan Port and its reinforcement of primacy with respect to fierce hinterland rivalry. It also demonstrates that an interplay between major ports and their corresponding hinterlands evolves from the transitional stage, characterized by lagging port service, to the multi‐stage, wherein the supply of ports partly outstrips hinterland demand. 相似文献

The aim of this study was to evaluate the prognostic value of concurrent measurement of
serum phosphorylated neurofilament heavy subunit (pNF-H) concentration and intramedullary
T2W hyperintensity in paraplegic to paraplegic dogs. Our hypothesis was that concurrent
measurement of these would provide a more accurate prediction of functional outcome in
dogs with thoracolumbar intervertebral disc herniation (IVDH). A prospective case-control
clinical study was designed using 94 dogs with acute onset of thoracolumbar IVDH. The
association of serum pNF-H concentration, T2W hyperintensity on sagittal MRI (T2H/L2),
deep pain perception and surgical outcome were evaluated with logistic regression analysis
after three months for all 94 surgically treated dogs. Sensitivity to predict
non-ambulatory outcome was compared among pNF-H and T2H/L2 and combination of both.
Logistic regression analysis indicated that serum pNF-H concentration and T2H/L2 were
significantly correlated with surgical outcome (P<0.05); however, deep
pain perception was not (P=0.41). The results of logistic regression
analysis indicated that the odds ratios of unsuccessful long-term outcome were 2.6 for
serum pNF-H concentration, 1.9 for T2H/L2 and 2.3 for deep pain sensation. The sensitivity
and specificity to predict non-ambulatory outcome for using serum parameter pNF-H>2.6
ng/ml, using T2H/L2 value of>0.84 and using both
serum pNF-H and T2H/L2, were 95% and 75.7%, 65% and 86.5%, and 90.0% and 97.5%,
respectively. Therefore, combined measurements of serum pNF-H and T2H/L2 might be useful
for predicting long-term outcome in dogs with thoracolumbar IVDH. 相似文献

We histopathologically and immunohistochemically investigated a case of malignant
lymphoma that spontaneously developed in a male common marmoset at two years of age.
Beginning at two years four months of age, the animal had an enlargement of the
submandibular and inguinal lymph nodes, small subcutaneous nodules near the right breast
and an approximately fivefold increase in peripheral lymphocyte count compared with the
previous examination value. The postmortem findings at two years eight months of age
showed lymphadenopathy with enlargement of the thymus and spleen. Small- to
intermediate-sized neoplastic lymphocytes had diffusely proliferated in the enlarged
nodes. The neoplastic cells were pleomorphic and had irregularly shaped nuclei. The
nuclear chromatin staining revealed hyperchromatism in the small-sized cells, and the
intermediate-sized cells exhibited vesicular staining. An immunohistochemical examination
indicated that the neoplastic lymphocytes were positive for CD3 and negative for CD20,
thus suggesting that they had originated from T cells. In addition, the proliferation of
high endothelial venules and reactive epithelioid histiocytes was observed. Scattered
tingible body-laden macrophages were infrequently detected. Neoplastic lymphocytes were
also observed in the thymus, spleen, heart, lungs, liver, kidneys, adrenal glands and
femoral and sternal bone marrow. This malignant lymphoma in a young male common marmoset
was considered to fit the category of “peripheral T-cell lymphoma, not otherwise specified
(PTCL-NOS)” according to the new WHO system of classification. 相似文献

The effect of blue LED on melatonin secretion, feeding behaviour and growth was addressed in Holstein female dairy calves. In Exp.1, six animals (8 weeks old, 97 ± 4.1 kg BW) were exposed to yellow or blue LED for 2 hr before darkness over 7 days under a long‐day photoperiod (LDPP). In Exp. 2, six animals (8 weeks old, 88.5 ± 4.8 kg BW) were exposed to blue light from a white LED all daytime or a yellow LED for 2 hr before the darkness of LDPP (blue light cut) over 3 weeks. In Exp. 1, blue light mildly suppressed melatonin secretion during the 2‐hr treatment but did not affect the timing of the nightly melatonin rise. However, the rise in nighty melatonin levels was higher with yellow than blue LED. In Exp. 2, white LED completely suppressed melatonin secretion during the 2‐hr treatment, but plasma melatonin concentrations were similar during the darkness. Grass hay intake, rumination time, frequency of water intake and body weight gain were higher in animals exposed to the yellow rather than the white LED. Overall results indicate that exposure to blue light from white LEDs under an LDPP suppresses melatonin secretion and might negatively impact the development of female dairy calves. 相似文献

Liver-type fatty acid-binding protein (L-FABP) is a biomarker for the early detection of renal diseases in humans. L-FABP is a cytotoxic oxidation product secreted from the proximal tubules under ischemic and oxidative stress conditions. First, L-FABP gene expression in the kidney and liver was evaluated. Next, the urinary L-FABP concentrations in dogs with or without renal diseases were measured using a novel enzyme-linked immunosorbent assay kit. Urinary L-FABP was normalized relative to urinary creatinine (uCre) concentrations (µg/g uCre). Finally, the relationships between urinary L-FABP and renal biomarkers used in canine medicine or serum alanine transaminase (ALT) as an indicator of liver damage were examined. Serum and urine samples from 94 client-owned dogs including 23 dogs with renal diseases and 71 dogs without renal diseases were used for analysis. Relative L-FABP gene expression was confirmed both in the liver and kidney. Dogs with renal diseases had a significantly higher urinary L-FABP than those without, and its predictive cutoff value was 26 µg/g uCre. Urinary L-FABP was significantly correlated with serum creatinine (r=0.4674, P<0.01), urea nitrogen (r=0.4907, P<0.01), urine specific gravity (r=−0.5100, P<0.01), and urine protein/creatinine ratio (r=0.7216, P<0.01), but not with serum ALT. Hence, dogs with a high urinary L-FABP value were more likely to have renal diseases. 相似文献

A high-pressure phase of titanium dioxide (TiO(2)) with an alpha-PbO(2)-type structure has been identified in garnet of diamondiferous quartzofeldspathic rocks from the Saxonian Erzgebirge, Germany. Analytical electron microscopy indicates that this alpha-PbO(2)-type TiO(2) occurred as an epitaxial nanometer-thick slab between twinned rutile bicrystals. Given a V-shaped curve for the equilibrium phase boundary of alpha-PbO(2)-type TiO(2) to rutile, the stabilization pressure of alpha-PbO(2)-type TiO(2) should be 4 to 5 gigapascals at 900 degrees to 1000 degrees C. This suggests a burial of continental crustal rocks to depths of at least 130 kilometers. The alpha-PbO(2)-type TiO(2) may be a useful pressure and temperature indicator in the diamond stability field. 相似文献

Summary A linkage map for watermelon (Citrullus lanatus) was constructed on the basis of RADP, ribosomal DNA restriction fragment length polymorphism (RFLP), isozyme, and morphological markers using F1BC1. A segregating population of 78 individuals was the result of a backcross of a cultivated inbred line (H-7; Citrullus lanatus; 2n=22) and a wild form (SA-1; C. lanatus; 2n=22), in which the latter was the recurrent (male) parent. A total of 69 RAPD, one RFLP, one isozyme, and three morphological markers was found to segregate in the BC1 population. Linkage analysis revealed that 62 loci could be mapped to 11 linkage groups that extended more than 524 centimorgans (cM), while 12 loci segregated independently of all other markers. The locus for exocarp color was linked to two RAPD markers within a region of 5 cM on linkage group 4. The locus for flesh color was linked to a RAPD marker within a region of 30 cM on linkage group 6. The isozyme marker GOT was located on the linkage group 1. Linkage group 2 contained a locus for ribosomal DNA within 5 cM of a RAPD marker. Half of the RAPD markers on the linkage group 7 displayed severely distorted segregation. The construction of linkage map using molecular markers is necessary for the breeding of watermelon to introduce useful gene of wild watermelon efficiently. However the linkage map that was constructed for the most part on the basis of RAPD markers could not cover significant parts of the genome, the linkage map provides breeders of watermelons the possibility of tagging useful agronomic traits, as well as the gene for exocarp color.Abbreviations RAPD
