Since the early 2000s, there has been a continued interest in lie detection using functional magnetic resonance imaging (fMRI) in neuroscience and forensic sciences, as well as in newly emerging fields including neuroethics and neurolaw. Related fMRI studies have revealed converging evidence that brain regions including the prefrontal cortex, anterior cingulate cortex, parietal cortex, and anterior insula are associated with deceptive behavior. However, fMRI-based lie detection has thus far not been generally accepted as evidence in court, as methodological shortcomings, generalizability issues, and ethical and legal concerns are yet to be resolved. In the present review, we aim to illustrate these achievements and limitations of fMRI-based lie detection.

Background: Detection of anti-human leukocyte antigen (HLA) antibodies is important during the selection of an appropriate donor prior to organ transplantation and also for monitoring the patients after transplantation. In this study, we compared antibodies detected via C3d assays, which monitors C3d complement-binding activities of HLA antibodies with those detected via single antigen bead (SAB) assays. Methods: A total of 66 serum samples were tested in parallel by SAB assays (Immucor Transplant Diagnostics, USA) and C3d assays (Immucor) for the detection of HLA class II antibodies. The relationship between these two methods was analyzed based on the types, numbers, median fluorescent intensity (MFI) values, and positivity of the antibodies using MATCH IT! Antibody (Immucor) program. Results: The number of antibodies obtained based on SAB and C3d assays was the highest with 24 samples (36.4%) in the 11–20 range and 23 (34.8%) in the 2–5 range detected via each assay. Among the SAB-positive antibodies, only 28 (6.4%) of the 440 antibodies with MFI ≤3,000 were C3d-positive, and 341 (61.3%) of the 556 antibodies with MFI ≥3,001 were C3d-positive. Whereas, among the 442 C3d-positive antibodies, SAB assays were positive except for 32 (7.2%) and 41 (9.3%) antibodies in the sections of MFI ≤500 and 1,001 ≤MFI ≤10,000, respectively. C3d-positive samples had higher maximum MFI values based on SAB assays, compared with C3d-negative samples. Conclusions MFI values of HLA class II antibodies detected through SAB assays in C3d-positive samples were higher than those in C3d-negative samples.

Plasma exchange performed with the aid of acid-citrate-dextrose formula A (ACD-A) is generally regarded as safe. However, unfractionated heparin (UFH) can serve as an anticoagulant for patients experiencing serious side effects such as anaphylaxis. No guidelines have currently been defined for the stand-alone UFH dosing during plasma exchange. We describe here two patients who developed anaphylaxis to ACD-A during plasma exchange, and we successfully used UFH as a standalone anticoagulant. The first patient was a 55-year-old man who required plasma exchange before ABO-incompatible kidney transplantation. During plasma exchange, he developed an allergic reaction. Thereafter, UFH was used as a standalone anticoagulant during four sessions of plasma exchange; the UFH (5,000 units) was added to a 500 mL normal saline bag and the UFH:whole blood ratio was maintained at 1:28. The second patient was an 80-year-old woman with steroid pulse-resistant neuromyelitis optica. She developed an allergic reaction during the first session of plasma exchange. The patient subsequently underwent five successful sessions of plasma exchange using UFH as a standalone anticoagulant. These findings may be useful when establishing a protocol for UFH as a standalone anticoagulant during plasma exchange in patients who develop an allergic reaction to citrate.
