Introduction: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is the most common inherited enzyme disorder in red blood cell (RBC). Due to the importance of G6PD enzyme as an antioxidant in RBC, we tried to investigate the oxidative damage in red cell concentrates (RCCs) prepared from donors with G6PD enzyme deficiency in comparison with healthy donors.
Material Method: This cross-sectional study was conducted on 20 male donors.
Background: Red blood cell (RBC) units undergo metabolic, structural, and biochemical changes known as "storage lesions" that can reduce the survival and quality of RBCs. The use of antioxidants such as α-tocopherol may help to improve the quality of RBC units by reducing oxidative stress. The aim of this study was to determine the antioxidant effect of α-tocopherol in RBC units containing citrate-phosphate-dextrose solution with adenine (CPDA1) stored at 1°C-6°C for 35 days.

Platelets are prone to activation during storage. Moreover, elevated free mitochondrial DNA (mtDNA) levels in PCs are associated with a higher risk of adverse transfusion reactions.

Therefore, the use of statins is very effective in reducing cholesterol and can reduce the risk of thrombosis in these patients. Rosuvastatin, a member of the statin family which, inhibits cholesterol synthesis.

Our pervious study revealed that the expression of miR-145 and miR-326 changed significantly in platelets under maintenance conditions. This study aimed to evaluate the effect of L-carnitine (LC) as an additive to augment platelet quality by changing the microRNA expression.

Methods: The PCs, have received from Iranian blood transfusion organization (IBTO).
Oxidative stress and mitochondrial damage are causes of platelet storage lesions (PSLs). Mitochondrial damage causes mitochondrial DNA (mtDNA) to be released into the extracellular space. MtDNA in platelet concentrates is considered damage-associated molecular patterns (DAMPs) and is one of the major causes of PSLs.

Mitochondrial damage causes mitochondrial DNA (mtDNA) to be released into the extracellular space. In this study, we evaluated the effect of L-carnitine (LC) as an antioxidant on free mtDNA DAMPs release in PCs during storage.

The potential role and importance of the microRNAs in diagnosis of this process could be remarkable. The aim of this study was to determine miR-145 and miR-326 associated with apoptosis during PC storage.

Strength platelet against oxidative stress conditions lead to decrease in platelet storage lesion (PSL). This study was aimed to evaluate L-carnitine (LC) effects on platelet oxidative stress and platelet apoptosis during storage time.

During storage, erythrocytes release an increasing number of microvesicles (MVs) that have key roles in biological processes. We aimed to investigate the procoagulant activity (PCA) of RBC-derived MVs during storage.

However, the low survival rate of these cells restricts their therapeutic applications. It is hypothesized that autophagy might play an important role in cellular homeostasis and survival.

Methods: From the randomly invited individuals (2,292), 698 out of the 916 males and 1,351 out of the 1,376 females participated in the study (participation rate: 76.2% and 98.
Aim: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran.
Methods: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken.
