Применение метода долгосрочного прогнозирования водонефтяного фактора для определения максимально возможного расчётного объёма добычи нефти месторождения "Чёрный Дракон", Вьетнам

Objective - Although junctional adhesion molecule-A (JAM-A) has recently been implicated in leukocyte recruitment on early atherosclerotic endothelium and after reperfusion injury, its role in neointima formation after arterial injury remains to be elucidated. Methods and Results - Here we show that the genetic deletion of JAM-A in apolipoprotein E - deficient (apoE(-/-)) mice significantly reduced neointimal hyperplasia after wire injury of carotid arteries without altering medial area. This was associated with a significant decrease in neointimal macrophage content, whereas the relative content of smooth muscle cells and endothelial recovery was unaltered in JAM-A(-/-) apoE(-/-) compared with JAM-A(-/-) apoE(-/-) lesions. In carotid arteries perfused ex vivo, deficiency in JAM-A significantly impaired the recruitment of monocytes 1 week, but not 1 day, after injury. These effects were paralleled by an attenuation of monocyte arrest and transmigration on activated JAM-A(-/-) apoE(-/-) versus JAM-A(-/-) apoE(-/-) endothelial cells under flow conditions in vitro. A mechanism underlying reduced recruitment was implied by findings that the luminal expression of the arrest chemokine RANTES in injured arteries and its endothelial deposition by activated platelets in vitro were diminished by JAM-A deficiency. Conclusions - Our data provide the first evidence to our knowledge for a crucial role of JAM-A in accelerated lesion formation and monocyte infiltration in atherosclerosis-prone mice

Problems of methodological determination of the place of financial and budgetary control in the system of state financial control

The relevance of this report due to the presence of problems in the field of budgetary control at all levels of the Russian budget system, which leads to numerous cases of misuse and inefficient use of budget funds and other public property, overestimation of the cost of purchased goods, works and services for state and municipal needs, the use of other corruption schemes in the budget mechanism

Identifying chemokines as therapeutic targets in renal disease: Lessons from antagonist studies and knockout mice

Chemokines, in concert with cytokines and adhesion molecules, play multiple roles in local and systemic immune responses. In the kidney, the temporal and spatial expression of chemokines correlates with local renal damage and accumulation of chemokine receptor-bearing leukocytes. Chemokines play important roles in leukocyte trafficking and blocking chemokines can effectively reduce renal leukocyte recruitment and subsequent renal damage. However, recent data indicate that blocking chemokine or chemokine receptor activity in renal disease may also exacerbate renal inflammation under certain conditions. An increasing amount of data indicates additional roles of chemokines in the regulation of innate and adaptive immune responses, which may adversively affect the outcome of interventional studies. This review summarizes available in vivo studies on the blockade of chemokines and chemokine receptors in kidney diseases, with a special focus on the therapeutic potential of anti-chemokine strategies, including potential side effects, in renal disease.

The aorta can act as a site of naïve CD4+ T-cell priming

Aims: Aortic adaptive immunity plays a role in atherosclerosis; however, the precise mechanisms leading to T-cell activation in the arterial wall remain poorly understood. Methods and results: Here, we have identified naïve T cells in the aorta of wild-Type and T-cell receptor transgenic mice and we demonstrate that naïve T cells can be primed directly in the vessel wall with both kinetics and frequency of T-cell activation found to be similar to splenic and lymphoid T cells. Aortic homing of naïve T cells is regulated at least in part by the P-selectin glycosylated ligand-1 receptor. In experimental atherosclerosis the aorta supports CD4+ T-cell activation selectively driving Th1 polarization. By contrast, secondary lymphoid organs display Treg expansion. Conclusion: Our results demonstrate that the aorta can support T-cell priming and that naïve T cells traffic between the circulation and vessel wall. These data underpin the paradigm that local priming of T cells specific for plaque antigens contributes to atherosclerosis progression

Numerical solution of gas dynamics equations on the computational meshes with arbitrary number of cell faces using high order spatial accuracy schemes

In the present study methodology and algorithm of numerical solution of gas dynamics equations on the computational meshes with arbitrary number of cell faces using high order spatial accuracy schemes is presented. For realization of calculation algorithm, the system of data storage is offered, the system does not depend on mesh topology, and it allows to use the computational meshes with arbitrary number of cell faces

Role of the CX3C chemokine receptor CX3CR1 in the pathogenesis of atherosclerosis after aortic transplantation

Background: The CX3C chemokine receptor CX3CR1 is expressed on monocytes as well as tissue resident cells, such as smooth muscle cells ( SMCs). Its role in atherosclerotic tissue remodeling of the aorta after transplantation has not been investigated. Methods: We here have orthotopically transplanted infrarenal Cx3cr1(-/-) Apoe(-/-) and Cx3cr1(+/+) Apoe(-/-)aortic segments into Apoe(-/-) mice, as well as Apoe(-/-) aortic segments into Cx3cr1(-/-) Apoe(-/-)mice. The intimal plaque size and cellular plaque composition of the transplanted aortic segment were analyzed after four weeks of atherogenic diet. Results: Transplantation of Cx3cr(-/-) Apoe(-/-) aortic segments into Apoe(-/-) mice resulted in reduced atherosclerotic plaque formation compared to plaque size in Apoe(-/-) or Cx3cr1(-/-) Apoe(-/-) mice after transplantation of Apoe(-/-) aortas. This reduction in lesion formation was associated with reduced numbers of lesional SMCs but not macrophages within the transplanted Cx3cr(-/-) Apoe(-/-) aortic segment. No differences in frequencies of proliferating and apoptotic cells could be observed. Conclusion These results indicate that CX3CR1 on resident vessel wall cells plays a key role in atherosclerotic plaque formation in transplanted aortic grafts. Targeting of vascular CX3CL1/ CX3CR1 may therefore be explored as a therapeutic option in vascular transplantation procedures
