To carry out normovolemic haemodilution in the best security conditions we elaborate a new method of preoperative haemodilution. Collection of red cell concentrates and adequate compensation are made either in the blood bank or at the patient's bed side. There are two ways of proceeding: *manual plasmapheresis technic is used for the collection of less than 450 ml packed red cells; *collection of more than 450 ml packed red cells is carried out on a PCS Haemonetics cell separator. CPD autologous red cells concentrates prepared in that way can be stored to meet the patient's need during and after the operation. The patient is identified as donor and receiver as regards laboratory analysis and computer treatment as well. Information's transmission between blood bank hospital and clinics is secured with the same document. This method enables homologues transfusion save and completes autologous transfusion in 68% cases among 106 patients. It is to be noticed that none of the 98 haemodiluted patients suffered from thrombosis.

Background: Patients with hematological malignancies are at high-risk of Clostridium difficile infection (CDI). Oral vancomycin is a first-line treatment for CDI. Vancomycin has been widely reported to induce flushing syndrome (also known as Red man syndrome), a well-known hypersensitivity reaction mostly occurs after intravenous administration.

Hypochlorous acid (HClO/ClO) is a common ROS that exhibits elevated activity levels in cancer cells. In this study, an ClO-triggered TADF probe, PTZ-MNI, was designed based on a naphthalimide core. PTZ-MNI self-assemble in aqueous environments, exhibiting significantly enhanced fluorescence that demonstrated typical aggregation-induced delayed fluorescence (AIDF) characteristics.

Cell viability assessment plays a crucial role in biological research, pharmaceutical development, and toxicological identification. Here, we used GelRed, a sensitive and safer nucleic acid dye, to selectively label dead cells with red fluorescence (FL) thus distinguishing dead cells from live ones. Further more, the combined use of GelRed and SYTO 9 (another nucleic acid dye) enabled the clear differentiation in FL spectra between the two physiological statuses.

A sustained blood-stage infection of the human malaria parasite P. falciparum relies on the active exit of merozoites from their host erythrocytes. During this process, named egress, the infected red blood cell undergoes sequential morphological events: the rounding-up of the surrounding parasitophorous vacuole, the disruption of the vacuole membrane and finally the rupture of the red blood cell membrane.

Background: During orthotopic liver transplantation, allograft reperfusion is a dynamic point in the operation and often requires vasoactive medications and blood transfusions. Normothermic machine perfusion (NMP) of liver allografts has emerged to increase the number of transplantable organs and may have utility during donation after circulatory death (DCD) liver transplantation in reducing transfusion burden and vasoactive medication requirements.
Methods: This is a single-center retrospective study involving 226 DCD liver transplant recipients who received an allograft transported with NMP (DCD-NMP group) or with static cold storage (DCD-SCS group).
