Objective Most high-risk thrombotic antiphospholipid syndrome (APS) patients test positive for anti-?2-glycoprotein I (a?2GPI) and anti-phosphatidylserine/prothrombin (aPS/PT) antibodies. Information on the influence of these antibodies thrombin generation activated protein C resistance (aPCr) is still sparse contradictory. Methods Plasma 16 poured into a ?2GPI affinity column allowed perfect s...

introduction: the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. these inhibitors are necessary to prevent thromboembolism. hereditary deficiency of inhibitors is the main cause of alteration in balance between the anti-clotting and the formation of thrombin. patients with this abnormality are susceptible to venous thromboembolism (vte). two major clinica...

objective: colorectal cancer (crc) is one of the most common and aggressive cancers worldwide. the majority of crc cases are sporadic that caused by somatic mutations. the adenomatous polyposis coli (apc; omim 611731) is a tumor suppressor gene of wnt pathway and is frequently mutated in crc cases. this study was designed to investigate the spectrum of apc gene mutations in iranian patients wit...

CONTEXT Factor V Leiden (FVL) is the most common heritable cause of venous thrombosis. It is caused by a single nucleotide substitution resulting in an R506Q missense mutation, resulting in factor V resistance to activated protein C (APC) inactivation. Carriers of FVL have an increased susceptibility to venous thrombosis, which is further increased in the presence of other genetic or environmen...

Spin-dependent quantum transport properties in twisted carbon nanotube and stretched carbon nanotube are calculated using density functional theory (DFT) and non-equilibrium green’s function (NEGF) formulation. Twisting and stretching have no effect on spin transport in CNTs at low bias voltages. However, at high bias voltages the effects are significant. Stretching restricts any spin-up curren...

With its significant contribution to cancer mortality globally, advanced colorectal (CRC) requires new treatment strategies. However, despite recent good results for mismatch repair (MMR)‑deficient CRC and other malignancies, such as melanoma, the vast majority of MMR‑proficient CRCs are resistant checkpoint inhibitor (CKI) therapy. commonly develop from precursor adenomas with enhanced Wnt‑sig...

Low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol levels are associated, respectively, with either increased risk or apparent protective effects for atherothrombosis. The ability of purified LDL and HDL to downregulate thrombin formation, a contributor to atherothrombotic processes, was assessed. Purified HDL, but not LDL, significantly enhanced inactivation of coagul...

BACKGROUND An increased incidence of deep venous thrombosis (DVT) has been described in multiple myeloma (MM). A recently described mechanism of hypercoagulability in cancer patients including MM patients is acquired activated protein C resistance (APC-R). The purpose of the present study was to examine the association between the combination of thalidomide plus chemotherapy and DVT development...
