Aims: It is commonly known that stored blood and blood products are heated before transfusion to prevent hypothermia, which leads to increased di-(2-ethylhexyl) phthalate (DEHP) content leaching into the blood and blood products and thereby causes greater conversion of DEHP to mono (2-ethylhexyl) phthalate (MEHP). However, there has been no study in the literature reporting on the amount of toxic phthalates in blood following the erythrocyte suspension (ES) transfused via warming. In this study, we aimed to investigate the DEHP and MEHP content in blood following the heated ES transfusions administered by DEHP-containing and DEHP-free infusion sets.

The most common cardiac tumor in adults is myxoma with its benign character. The results of cardiac tumors resected with open cardiac surgery in our center are reported in this study.

Article Synopsis
- The study investigates how common acute pancreatitis is among patients with acute brucellosis and what factors contribute to its occurrence.
- It involved analyzing data from adult brucellosis patients, checking their blood samples for various indicators, including specific antibody levels and enzyme concentrations.
- Results showed that patients with both conditions had higher levels of certain enzymes and blood sugar, but lower hemoglobin, which might help in evaluating the severity of their conditions.
Article Synopsis
- HDV infection can lead to thyroid problems, which complicate interferon treatment for chronic infection.
- The study reviewed 127 C-HDV patients, finding a 4.7% rate of hypothyroidism and no cases of hyperthyroidism.
- A notable correlation was found between thyroid autoantibodies, elevated liver enzymes, and HDV-RNA levels, indicating potential underlying connections that require further research.
The main focus of our study is to investigate how the performance of digital timing methods is affected by sampling rate, anti-aliasing and signal interpolation filters. We used the Nyquist sampling theorem to address some basic questions such as what will be the minimum sampling frequencies? How accurate will the signal interpolation be? How do we validate the timing measurements? The preferred sampling rate would be as low as possible, considering the high cost and power consumption of high-speed analog-to-digital converters. However, when the sampling rate is too low, due to the aliasing effect, some artifacts are produced in the timing resolution estimations; the shape of the timing profile is distorted and the FWHM values of the profile fluctuate as the source location changes.
