One hundred and ninety-five donors identified based on a history of hematoma and 2434 blood donors were included in the study. Eighty-eight donors (3.6%) had a bleeding score indicating a potential bl...
The bleeding questionnaire proved to be a valuable tool to screen blood donors for potential platelet defects. Platelet dysfunction was rare in the blood donor population assessed. Additional studies ...
Margination describes the movement of particles toward the endothelial wall within blood vessels. While there have been several studies tracking the margination of spherical particles in blood, the be...
Parkinson's disease (PD) is a progressive neuronal illness often linked to increased cardiovascular complications, such as myocardial infarction, cardiomyopathy, congestive heart failure, and coronary...
To gain a better understanding of platelet dysfunction in PD, we investigated the impact of 6-hydroxydopamine (6-OHDA), an analog of dopamine that simulates PD by destroying dopaminergic neurons, on h...
Our findings showed that 6-OHDA treatment increased the production of ROS in human blood platelets. The increase in ROS was confirmed by the ROS scavenger, NAC, and was also reduced by inhibiting the ...
Our findings suggest that the 6-OHDA-induced ROS production is regulated by the IP...
Storage of platelet concentrates (PCs) has an impact on platelet quality and possibly affects their functions after transfusion. The influence of processing and storage conditions of PCs on their in v...
Two methods of biotinylation were compared to a control (standard PC). The "Bio-Wash" process used washing steps to label all platelets within the PC; for the other method, "Bio-Direct," one fifth of ...
Both methods achieved a stable labeling through the storage, with similar platelet counts and metabolism in comparison to control PCs. Bio-Wash showed higher activation phenotype and lower aggregation...
We set up two methods of biotinylation that can be easily implemented in a blood bank environment. The Bio-Direct process was preferred to the Bio-Wash because of its similarity, from a functional and...
Tigecycline with broad-spectrum activity against pathogens has advantages in the treatment of severe infections in clinical. Accompany with the huge increase of tigecycline usage, more side effects be...
Platelet (PLT) transfusions are essential for advanced hospitals, especially those with onco-hematology departments. However, platelet concentrates (PCs) have supply limitations and a shorter shelf li...
This retrospective study was conducted over a 4-year period between January 2017 and January 2021 in a tertiary referral hospital. From the beginning of 2020, as a new strategy of our TS, a PLT invent...
In 2017, a total of 799 PPCs were used and 70 PPCs were discarded with the expiration ratio (ER) of 8.0%. In 2018, 1124 PPCs were used and 99 PPCs were discarded with the ER of 7.4%. In 2019, 726 PPCs...
The results of the current study suggested that with the determination of the platelet stock level and the use of out-of-group PCs, the rate of discarded PLT could be reduced. Nevertheless, based on c...
In a recent study, 13.8% of blood donors had reported cannabis use in the 72 hours preceding their donation, and these donors are not deferred under existing criteria in Canada. This high prevalence r...
To mimic pre-donation cannabis use, whole blood was collected and exposed (in vitro) to varying concentrations (range: 1-24 μg/mL) of a cannabinoid mixture (CM) overnight. Whole blood was then separat...
In the RBC fraction, free hemoglobin levels were increased in a dose-dependent manner after the addition of a cannabinoid mixture to whole blood. Hemolysis and methemoglobin levels were significantly ...
An in vitro exposure to a cannabinoid mixture hemolyzed RBCs, impaired oxygen transport by RBCs, reduced platelet counts, and impaired platelet function. These results suggest that pre-donation cannab...
The study was planned to determine the association of blood donor characteristics with in vitro quality of platelets....
In the prospective observational study, a total of 85 male whole blood donors in the age group of 18-30 and 45-65 years were enrolled using purposive sampling method. Serum total cholesterol, glycosyl...
Median MPV was higher in platelets from older blood donors on day five (9.8 vs 9.4, p = 0.037). Median LDH levels were also higher in platelets on day one and five from older donors (Day one: 204.5 vs...
In vitro platelet storage properties are affected by blood donor characteristics....
Platelets are anucleate blood cells that contain mitochondria and regulate blood clotting in response to injury. Mitochondria contain their own gene expression machinery that relies on nuclear-encoded...
