Endoplasmic reticulum (ER) stress activates a set of signaling pathways, collectively termed the unfolded protein response (UPR). The three UPR branches (IRE1, PERK, and ATF6) promote cell survival by reducing misfolded levels. also promotes apoptotic death if ER is not alleviated. How integrates its cytoprotective proapoptotic outputs to select between life or fates unknown. We found that IRE1 ATF6 activities were attenuated persistent in human cells. By contrast, PERK signaling, including...

BACKGROUND AND METHODS: From 1996 through 2006, 195 cases were reported as transfusion‐related acute lung injury (TRALI) to the Serious Hazards of Transfusion scheme and from 1999 onward classified by probability, using clinical features HLA and/or HNA typing. late 2003, National Blood Service provided 80 90 percent fresh‐frozen plasma (FFP) for platelet (PLT) pools male donors. RESULTS: Forty‐nine reports highly likely/probable TRALI, 51 possible/unlikely. Of 96 investigations, donor...

Cerebral microbleeds are a potential neuroimaging biomarker of cerebral small vessel diseases that prone to intracranial bleeding. We aimed determine whether presence can identify patients at high risk symptomatic haemorrhage when anticoagulated for atrial fibrillation after recent ischaemic stroke or transient attack.

Antiphospholipid antibodies (APA), lupus anticoagulant (LA) and/or anticardiolipin (ACA), are associated with thrombosis and recurrent miscarriage. We studied the outcome of 20 pregnancies in women (median age 32 years; range 23-41) APA (14 LA positive; three immunoglobulin (Ig) G ACA two IgM positive one IgG positive) history miscarriage 4; 3-11) who declined pharmacological treatment their next pregnancy.

In 1991, the Haemostasis and Thrombosis Task Force of British Society for Haematology published guidelines on testing lupus anticoagulant (LA) (Machin et al, 1991). Since then there have been major developments in our understanding nature 'antiphospholipid antibodies' (aPLs) improvements knowledge clinical course antiphospholipid syndrome. These revised prepared against this background. They cover both laboratory aspects. Although most early observations were LA anticardiolipin (aCL), it is...

Summary Thrombotic thrombocytopenic purpura (TTP) is a life‐threatening disorder and plasma exchange (PEX) remains the primary treatment modality. Twenty‐five patients with acute refractory/relapsing idiopathic TTP received rituximab in conjunction PEX because of progressive clinical disease or deterioration laboratory parameters, despite intensive standard therapy. In relapsing TTP, was started if antibody to ADAMTS‐13 (a disintegrin metalloproteinase thrombospondin motif‐13) demonstrated...

The prevalence persistently positive tests LA was 9.6% and immunoglobulin G (IgG) M (IgM) ACA 3.3 2.2% respectively. Only seven (1.4%) positive. Repeat testing, after an interval at least 8 weeks, demonstrated that only 65.7% positive, 36.6% IgG 36.0% IgM on...

The updated international consensus criteria for definite antiphospholipid syndrome (APS) are useful scientific clinical studies. However, there remains a need diagnostic routine use. We audited the results of antibodies (aPLs) in cohort 193 consecutive patients with aPL positivity-based testing lupus anticoagulant (LA), IgG and IgM anticardiolipin (aCL) anti-ß(2)glycoprotein-1 (aß(2)GPI). Medium/high-titre aCL/aβ(2)GPI was defined as >99th percentile. Low-titre positivity (>95(th )< 99(th)...
