Two-color whole blood lysis is the assay of choice for lymphocyte immunophenotyping because of the additional information it provides. Recently, artifactual double-staining of some specimens has been observed with this assay. In these cases, the samples appear to be uncompensated for spectral overlap or to inappropriately coexpress two antigens simultaneously. This artifact can result in the apparent coexpression of CD4 and CD8 (observed in lymphoblastic processes) or of CD5 and CD20 (characteristic of chronic lymphocytic leukemia) in normal persons, leading to an erroneous diagnosis. Using plasma, serum, or immunoglobulin preparations from donors who exhibit this artifact we sought to determine 1) the source of the artifact and 2) ways to overcome it. This staining is apparently due to an immunoglobulin in the donors' serum and plasma which does not have specific reactivity with mouse immunoglobulin. Washing whole blood samples or blocking with mouse immunoglobulin is a convenient way of avoiding this artifact.

Our aim was to determine the effects of P intake on P balance, serum parathyroid hormone (PTH) levels and bone resorption during the final 4 weeks prepartum and the first 8 weeks of lactation. Sixty pregnant multiparous Holstein Friesian dairy cows were assigned to a randomized block design with repeated measurements and dietary treatments arranged according to a 2 × 2 factorial design. The experimental diets contained 3.

This research explored the effect of high-fiber diet based on gut microbiota on chronic heart failure (HF) patients. Chronic HF patients, who had undergone a dietary survey indicating a daily dietary fiber intake of less than 15g/d were divided into the control and study groups (n = 50). In addition to conventional heart failure treatment, the study group received dietary guidance, while the control group did not receive any dietary guidance and maintained their usual low-fiber dietary habits.

Background: The selection and extent of application for both total adrenalectomy (TA) and partial adrenalectomy (PA) within this surgical approach continue to be matters of debate. This paper compares the postoperative efficacy and functional indicators of PA and TA to provide comprehensive insights for clinicians to consider the best surgical treatment options.
Methods: Systematic review on PubMed, Embase, Cochrane Library, Web of Science, and China National Knowledge Infrastructure (CNKI) was conducted.

The objective of the present study was to assess serum and cancerous tissue biometal levels in colorectal cancer (CRC) patients, and its relation to disease severity. A total of 90 CRC patients and 97 controls were involved in the present study. The level of biometals in blood serum and colon tissues (only in CRC cases) was evaluated by inductively-coupled plasma mass-spectrometry.
