Prognostic factors for breast cancer include axillary lymph node status, tumor size, histology, nuclear grade, presence of estrogen and progesterone receptors, HER2/neu status, and mean microvessel density (MVD). In this study, we evaluated the usefulness of a new marker, D2-40, by investigating lymph vascular invasion of the tumor immunohistochemically in 132 patients with breast cancer and co...
The existence of two molecular forms of D2 dopamine receptors suggests that differences in the distribution or regulation of the two forms could be exploited for the pharmacological treatment of disease. Using probes selective for each alternatively spliced variant of D2 receptor mRNA, we determined that both variants were widely distributed in rat brain and pituitary but that the ratio of the ...
BACKGROUND AND OBJECTIVES The optimal extent of lymphadenectomy in the treatment of gastric adenocarcinoma is debated. We compared gastrectomy outcomes following limited (D1) or extended (D2) lymphadenectomy. METHODS Using the multi-institutional US Gastric Cancer Collaborative database, we reviewed the morbidity, mortality, recurrence, and overall survival (OS) of patients receiving D1 or D2...
Let us consider analogous problem for the metric space (X, d) with at least four points. Let A,B,C ∈ X be three fixed points. Then, for the point M ∈ X we suppose that a triangle can be formed from the distances d1 = d(M,A), d2 = d(M,B) and d3 = d(M,C) iff the following conjunction of inequalities is true: d1 + d2 − d3 ≥ 0 and d2 + d3 − d1 ≥ 0 and d3 + d1 − d2 ≥ 0. (1.1) If in conjunction (1.1)...
UNLABELLED Human type II iodothyronine deiodinase (D2) catalyzes the activation of T(4) to T(3). The D2 enzyme, like the type I (D1) and type III (D3) deiodinases, contains a selenocysteine (SeC) residue (residue 133 in D2) in the highly conserved catalytic center. Remarkably, all of the D2 proteins cloned so far have an alanine two residue-amino terminal to the SeC, whereas all D1 and D3 prote...
چکیده تاثیر آگونیستهای دوپامین بردمای داخلی بدن موش سوری، موردآزمایش قرارگرفته است ونتایج زیربدست آمده اند :- 1 آپومرفین بصورت وابسته به دوز، دمای بدن موش راکاهش میدهد.این پاسخ بوسی آنتاگونیست گیرنده d2، سولپیراید،مهارشده است ولی sch 23390،آنتاگونیست گیرنده d1،اثری روی هیپوترمی ناشی از آپومرفین نداشته است .- 2 تجویز quinpirole،آگونیست گیرنده d2،نیز سبب هیپوترمی میگردد وسولپیرای جلوی این اثر رام...
An excess intake of vitamin D2 can result in mobilization of calcium in the skeleton and increase the serum calcium level. This calcium is taken up by soft tissues such as arteries. The risk of calcium builds up in arteries, a significant component of atherosclerotic plaque. Many researches clarify the relationship between oral contraceptives and atherosclerosis. This study aims to evaluate the...
Link between D1 and D2 dopamine receptors is reduced in schizophrenia and Huntington diseased brain.
Dopamine receptor types D1 and D2 can oppose or enhance each other's actions for electrical, biochemical, and psychomotor effects. We report a D1-D2 interaction in homogenized tissue as revealed by ligand binding. D2 agonists lowered the binding of [3H]raclopride to D2 receptors in striatal and anterior pituitary tissues. Pretreating the tissue with the D1-selective antagonist SCH 23390 prevent...
Although the dopamine D1-D2 receptor heteromer has emerging physiological relevance and a postulated role in different neuropsychiatric disorders, such as drug addiction, depression, and schizophrenia, there is a need for pharmacological tools that selectively target such receptor complexes in order to analyze their biological and pathophysiological functions. Since no selective antagonists for...
A graph is (d1, . . . , dr )-colorable if its vertex set can be partitioned into r sets V1, . . . , Vr where themaximum degree of the graph induced by Vi is at most di for each i ∈ {1, . . . , r}. Let Gg denote the class of planar graphs with minimum cycle length at least g . We focus on graphs in G5 since for any d1 and d2, Montassier and Ochem constructed graphs in G4 that are not (d1, d2)-co...
