A saline-adenine-glucose-phosphate-maltose (SAGP-maltose) quadruple-pack system was devised to improve the conventional method of preparing blood components. One of the features of this method is that high-speed centrifugation was used as the initial spin in the two-step centrifugation of whole blood. This feature permitted the removal of the buffy coat from red cells at the same time the platelets were isolated. Since the platelets were concentrated without forming a button, the damage to the platelets due to mechanical stress in preparation was minimized. Another major feature was the use of the SAGP-maltose solution. Maltose effectively prevented hemolysis during storage in a protein-poor medium for preserving red cells. Judging from the red cell adenosine triphosphate level and morphology score, it should be possible to store red cells for 35 to 42 days in SAGP-maltose preservative. In addition, approximately 25 percent more plasma was collected in the present system than in conventional multiple-pack systems.

Blood components play a crucial role in maintaining human health and accurately detecting them is essential for medical diagnostics. A cutting-edge sensor utilizing PCF revealed to precisely identify a wide range of blood components with WBCs (white blood cells), RBCs (red blood cells), HB (hemoglobin), platelets, and plasma. A numerical analysis was performed using COMSOL Multiphysics software to assess the capabilities of the sensor.

Background: Our previous study have demonstrated chronic intermittent hypoxia (CIH) induced cardiomyocyte apoptosis and cardiac dysfunction. However, the molecular mechanisms are complicated and varied. In this study, we first investigated the CaMKIIγ expression and signaling pathway in the pathogenesis of cardiomyocyte apoptosis after CIH.

Purpose: Liver and lung metastases demonstrate distinct biological, particularly immunological, characteristics. We investigated whether preoperative complete blood count (CBC) parameters, which may reflect the immune system condition, predict early dissemination to the liver and lungs in colorectal cancer (CRC).
Methods: In this retrospective single-centre study, we included 268 resected CRC cases with complete 2-year follow-up and analysed preoperative CBC for association with early liver or lung metastasis development.

Objectives: Osteoblast is known to regulate hematopoiesis according to preclinical studies but the causal relationship in human remains uncertain. We aimed to evaluate causal relationships of bone mineral density (BMD) with blood cell traits using genetic data.
Methods: Summary statistics from the largest available genome-wide association study were retrieved for total body BMD (TBBMD), lumbar spine BMD (LSBMD), femoral neck BMD (FNBMD) and 29 blood cell traits including red blood cell, white blood cell and platelet-related traits.

Department of Surgical, Medical, Biomolecular Pathology and Intensive Care, University of Pisa, Pisa, Italy.
Background And Aims: There is growing interest in the environmental impact of surgical procedures, yet more information is needed specifically regarding liver transplantation. This study aims to quantify the total greenhouse gas emissions, or carbon footprint, associated with adult whole-size liver transplantation from donors after brain death, including the relevant back-table graft preparation.
Methods: The carbon footprint was calculated retrospectively using a bottom-up approach.
