The antiphospholipid syndrome (APS) is diagnosed when patients with thrombotic complications or foetal losses have elevated levels of antiphospholipid antibodies in their plasmas. The term APS is confusing, because the pathogenic auto-antibodies are not directed against phospholipids but towards a plasma protein, β(2)-glycoprotein I. For many years the reason why auto-antibodies against β(2)-gl...

OBJECTIVE Prothrombin (PT) is one of the most important antigenic targets for aPL antibodies; however, the prothrombotic mechanism of anti-PT (aPT) antibodies in APS is not fully clarified. Considering that some autoantibodies possess the enzymatic activity, the aim of this study was to test the hypothesis that some aPT antibodies in APS may display prothrombinase activity. METHODS Six APS pa...

Annexin A5 (AnxA5) is a potent anticoagulant protein that crystallizes over phospholipid bilayers (PLBs), blocking their availability for coagulation reactions. Antiphospholipid antibodies disrupt AnxA5 binding, thereby accelerating coagulation reactions. This disruption may contribute to thrombosis and miscarriages in the antiphospholipid syndrome (APS). We investigated whether the antimalaria...

Although antiphospholipid antibody syndrome (APS) is an autoimmune condition that is primarily characterized by arterial or venous thrombosis or pregnancy morbidity and the presence of antiphospholipid antibodies (aPL), recent reviews have introduced non-thromboembolic manifestations. We describe the case of a 58-year-old woman with vegetation on the aortic valve, whose initial presentation of ...

Titanium is widely used for medical purposes. It related to bone repair because of its favorable mechanical properties and biocompatible ability osseointegrate in host tissue. A good lasting connection the implant with tissue possible when there are sufficient conditions grow into pores material, therefore use a porous titanium coating may be helpful solving this problem. In paper, shrouded pla...

Thermal-sprayed ceramic coatings are widely used in industry due to their favorable mechanical properties. However, traditional prone failure the differences physical properties between bonding coating and coating. In order solve this problem, a continuous transition zone was introduced coating, then air plasma spraying prepare coatings. The Vickers hardness analysis results show that existence...

The behavior and fate of alkylphenols (APs) were studied in surface water from the Jialu River, Henan Province, China. Located at its upper stream, Zhengzhou city is regarded as the major discharge source to this river with its annual effluents containing 726 kg for nonylphenol (NP) and 30.2 kg for octylphenol (OP). The concentrations of NP and OP in surface water ranged from 75.2 to 1520 ngL(-...

Abstract Corrosion performance of NiCr and NiCrBSi coatings produced by APS, HVOF, HVAF was studied electrochemical measurements immersion tests in 0.5 3.5 wt.% NaCl solutions. In the measurements, performed better than coatings. The effect coating process on corrosion resistance material significantly lower that selected materials, or NiCrBSi. All showed a tendency to passivate but suffered fr...

Several silicate materials were plasma sprayed and characterized by the authors in recent years from the point of view of their chemical and phase compositions, microstructure and mechanical as well as thermal properties. Present work is concerned with selected dielectric properties of these deposits. Synthetic mullite and steatite as well as natural olivine-forsterite were plasma sprayed using...
