Abstract
Background Pathogen inactivation treatment (PIT) has been shown to alter platelet function, phenotype, morphology and to induce a faster aging of platelet concentrates (PCs). Key pieces of information are still missing to understand the impacts of PITs at the cellular level. Objectives This study investigated the impact of amotosalen/UVA on PCs, from a post-translational modifications (PTM) point of view. Phosphoproteomic analyses were conducted on resting platelets, right after the amotosalen/UVA treatment and compared with untreated PCs. Method A two-arm study setting was carried out to compare PIT (amotosalen/UVA) to untreated PCs, on day 1 post-donation. Based on a pool-and-split approach, 12 PCs were split into two groups (treated and untreated). Quantitative phosphoproteomics was performed using TMT technology to study the changes of phosphoproteins right after the PIT. Results A total of 3,906 proteins and 7,334 phosphosites were identified, and 2,473 proteins and 2,214 phosphosites were observed in at least 5 to 6 replicates. Compared to untreated platelets, PIT platelets exhibited an upregulation of the phosphorylation effects, with 109 phosphosites identified with a higher than 2-fold change. Two pathways were clearly identified. The mitogen activated protein kinases (MAPKs) cascade, which triggers the granule secretion and the activation of the pS15 HSPB1. One of the shape change pathways was also observed with the inhibition of the Threonine 18 and Serine 19 phosphorylations on myosin light chain (MLC) protein after the amotosalen/UVA treatment. Conclusions This work provides a deep insight into the impact of amotosalen/UVA treatment from a phosphoprotein viewpoint on resting platelets. Clear changes in phosphorylation of proteins belonging to different platelet pathways were quantified. This discovery corroborates previous findings and fills missing parts of the effect of photochemical treatments on platelets.

Abstract
Despite the importance of the proper quality of blood products for safe transfusion, conventional methods for preparation and their preservation, they lack significant stability. Non-metal nanoparticles with particular features may overcome these challenges. This review study for the first time provided a comprehensive vision of the interaction of non-metal nanoparticles with each blood product (red blood cells, platelets and plasma proteins). The findings of this review on the most effective nanoparticle for improving the stability of RBCs indicate that graphene quantum dots and nanodiamonds show compatibility with RBCs. For increasing the stability of platelet products, silica nanoparticles exhibited a suppressive impact on platelet aggregation. Pristine graphene also shows compatibility with platelets. For better stability of plasma products, graphene oxide was indicated to preserve free human serum albumin from thermal shocks at low ionic strength. For increased stability of Factor VIII, mesoporous silica nanoparticles with large pores exhibit the superb quality of recovered proteins. Furthermore, 3.2 nm quantum dots exhibited anticoagulant effects. As the best promising nanoparticles for immunoglobulin stability, graphene quantum dots showed compatibility with γ-globulins. Overall, this review recommends further research on the mentioned nanoparticles as the most potential candidates for enhancing the stability and storage of blood components.

Abstract
Phosphatidylserine (PS) translocation to the external membrane leaflet represents a key mechanism in the pathophysiology of human erythrocytes (RBC) acting as an "eat me" signal for the removal of aged/stressed cells. Loss of physiological membrane asymmetry, however, can lead to adverse effects on the cardiovascular system, activating a prothrombotic activity. The data presented indicate that structurally related olive oil phenols prevent cell alterations induced in intact human RBC exposed to HgCl2 (5-40 µM) or Ca2+ ionophore (5 µM), as measured by hallmarks including PS exposure, reactive oxygen species generation, glutathione depletion and microvesicles formation. The protective effect is observed in a concentration range of 1-30 µM, hydroxytyrosol being the most effective; its in vivo metabolite homovanillic alcohol still retains the biological activity of its dietary precursor. Significant protection is also exerted by tyrosol, in spite of its weak scavenging activity, indicating that additional mechanisms are involved in the protective effect. When RBC alterations are mediated by an increase in intracellular calcium, the protective effect is observed at higher concentrations, indicating that the selected phenols mainly act on Ca2+-independent mechanisms, identified as protection of glutathione depletion. Our findings strengthen the nutritional relevance of olive oil bioactive compounds in the claimed health-promoting effects of the Mediterranean Diet.

Abstract
BACKGROUND AND OBJECTIVES Measurement of antioxidant power (AOP) can be useful to validate the execution of the pathogen inactivation (PI) treatment of plasma units. The aim of this study was to evaluate the Theraflex technology for plasma units routinely used in Belgium. MATERIALS AND METHODS AOP was tested on plasma units treated by Theraflex with various non-complete treatment scenarios. AOP was quantified electrochemically using disposable devices and was expressed as equivalent ascorbic acid concentration. RESULTS During a complete PI treatment, AOP rose from 195 ± 32 to 230 ± 42 μmol/L eq. ascorbic acid after addition of methylene blue (MB), and decreased to 192 ± 30 μmol/L eq. ascorbic acid after illumination and finally to 177 ± 27 μmol/L eq. ascorbic acid after final filtration. Without MB, the final filtration had no effect on the plasma AOP (197 ± 22 μmol/L eq. ascorbic acid before filtration and 194 ± 22 μmol/L eq. ascorbic acid after filtration). With no MB and no illumination, there was no significant difference between the plasma AOP at the beginning (188 ± 23 μmol/L eq. ascorbic acid) and at the end of the process (179 ± 21 μmol/L eq. ascorbic acid). CONCLUSION AOP measurement may not indicate the effectiveness of the PI treatment.

Abstract
OBJECTIVE Hemolysis is an indicator of storage lesion that occurs in stored packed red blood cells (pRBCs) over time. Intermittent mixing of red blood cells in the additive solutions may be beneficial but may also result in iatrogenic injury. Position of units in storage may also affect the quality of the pRBCs. This prospective study was designed to evaluate hemolytic effect of mixing frequency and storage position on canine pRBCs over a period of 28 days. DESIGN Prospective in vitro study SETTING: Private practice referral hospital with an internal blood bank ANIMALS: Thirty-two healthy prescreened dogs enrolled in a volunteer blood banking program INTERVENTIONS: None MEASUREMENTS AND MAIN RESULTS: A total of 160 samples were evaluated. Forty canine pRBC units were split into 4 daughter bags and stored in varying positions with different mixing frequencies. Samples were stored upright and mixed daily, upright and mixed weekly, horizontally and mixed daily, or horizontally and mixed weekly for a period of 28 days. At days 0, 7, 14, and 28, samples from the units were analyzed to calculate percent hemolysis. No differences were found in any hemolytic indicators investigated (total hemoglobin, free plasma hemoglobin, and packed cell volume) until day 28 in all test groups. Canine pRBCs stored upright and mixed weekly or stored horizontally and mixed weekly resulted in less hemolysis and free plasma hemoglobin when compared to units stored horizontally and mixed daily only at day 28. CONCLUSIONS Statistically significant hemolysis was not evident amongst canine pRBC groups less than 28 days old suggesting that positioning and mixing frequency was irrelevant until day 28. Beyond 28 days despite the presence of hemolysis, no definitive recommendation could be made with respect to best practice for storage position or mixing frequency of stored canine pRBCs.

Abstract
The storage of red blood cells for transfusion purposes induces modifications of biochemical and biological properties. Moreover, these modifications are modulated by the donors' characteristics and the cell processing. These ex vivo alterations were suspected to decrease the transfusion efficiency and even to induce adverse events. This short article will review the red blood cells storage lesions and the clinical data related to them. In particular, the questions regarding the donors and recipients sex will be discussed.

Abstract
BACKGROUND The production of platelet concentrates (PCs) is evolving, and their survival capacity needs in vivo evaluation. This requires that the transfused platelets (PLTs) be distinguished from those of the recipient. Labeling at various biotin (Bio) densities allows one to concurrently trace multiple PLT populations, as reported for red blood cells. STUDY DESIGN AND METHODS A method is described to label human PLTs at two densities of Bio for future clinical trials. Injectable-grade PLTs were prepared in a sterile environment, using injectable-grade buffers and good manufacturing practices (GMP)-grade Sulfo-NHS-Biotin. Sulfo-NHS-Biotin concentrations were chosen to maintain PLT integrity and avoid potential alloimmunization while enabling the detection of circulating BioPLTs. The impact of biotinylation on human PLT recirculation was evaluated in vivo in a severe immunodeficient mouse model using ex vivo flow cytometry. RESULTS BioPLTs labeled with 1.2 or 10 μg/ml Sulfo-NHS-Biotin displayed normal ultrastructure and retained aggregation and secretion capacity and normal expression of the main surface glycoproteins. The procedure avoided detrimental PLT activation or apoptosis signals. Transfused human BioPLT populations could be distinguished from one another and from unlabeled circulating mouse PLTs, and their survival was comparable to that of unlabeled human PLTs in the mouse model. CONCLUSIONS Provided low Sulfo-NHS-Biotin concentrations (<10 μg/ml) are used, injectable-grade BioPLTs comply with safety regulations, conserve PLT integrity, and permit accurate in vivo detection. This alternative to radioisotopes, which allows one to follow different PLT populations in the same recipient, should be valuable when assessing new PC preparations and monitoring PLT survival in clinical research.
