Abstract:
... Circulating tumor cells (CTCs), as a type of tumor, have attracted wide attention because of their characteristics of shedding from the primary tumor and spreading to other tissues and organs through peripheral blood. The circulating tumor DNA (ctDNA), the DNA released by CTCs and other tumor cells into the peripheral blood, was considered as a promising detection substance for clinical applicatio ...

Abstract:
... Although the in vivo toxicity of nanoplastics (NPs) has already been reported in different model systems, their effects on mammalian behavior are poorly understood. Thus, we aimed to evaluate whether exposure to polystyrene (PS) NPs (diameter: 23.03 ± 0.266 nm) alters the behavior (locomotor, anxiety-like and antipredator) of male Swiss mice, induces brain antioxidant activity, and erythrocyte DNA ...
... Erythrocytes are physiological entities that have been exploited in both preclinical and clinical trials for the delivery of exogenous agents. Over the years, diverse erythrocyte-derived carriers (ECs) have been developed with related patents granted for industrial and commercial purposes. However, most ECs have only been exploited for drug delivery. Serious discussions regarding their application ...
erythrocytes, etc ; Plasmodium falciparum; genes; parasitology; Show all 4 Subjects
Abstract:
... Relative resistance of Plasmodium falciparum parasites to artesunate (AS) has been ascribed to mutations in the Kelch 13 gene. Lee et al. describe another potential contributor to resistance: the induction of increased rosetting by trophozoite-infected erythrocytes following short exposures to AS. Dissecting this phenomenon may lead to new insights into AS resistance. ...

... Haemotropic mycoplasmas (haemoplasmas) are small pleomorphic bacteria infecting erythrocytes of several mammalian species, including human beings. No study to date has focused on the risk of bacteria exposure in hunting activities, particularly in natural environments of highly tick‐infested areas. Accordingly, the present study aimed to assess haemoplasma occurrence in the complex encompassing wi ...

Abstract:
... Red blood cell (RBC) membrane-hitchhiking nanoparticles (NPs) have been an increasingly popular supercarrier for targeted drug delivery. However, the kinetic details of the shear-induced NP detachment process from RBC in blood flow remain unclear. Here, we perform detailed computational simulations of the traversal dynamics of an RBC-NP composite supercarrier with tunable properties. We show that ...
erythrocytes, etc ; blood serum; humans; phase transition; temperature; Show all 5 Subjects
Abstract:
... The effects of Iodixanol contrast medium were studied on human blood samples with differential scanning calorimetry (DSC). Measurements on anticoagulated and non-anticoagulated samples revealed that the components of the plasma and serum turned into a thermodynamically less stable state in the presence of Iodixanol. The thermal parameters of the main transition peak changed in the same way for bot ...
erythrocytes, etc ; antioxidants; flavones; food chemistry; hemolysis; models; Show all 6 Subjects
Abstract:
... Flavonoids are considered beneficial, but they may exhibit pro-oxidative effects likely due to metal reducing properties. For the first time, 24 structurally related flavonoids were compared for copper reduction, and modulation of the copper-triggered Fenton reaction and lysis of erythrocytes. The vast majority of flavonoids reduced cupric ions; their behaviour ranged from progressive gradual redu ...

Abstract:
... The Haemogregarinidae family (Apicomplexa: Adeleina) comprises hemoprotozoa that infect mammals, birds, amphibians, fish, and reptiles. Some morphological characteristics of the Cyrilia lignieresi have been described previously, but the parasite–erythrocyte relationship is still poorly understood. In order to understand the structural architecture of C. lignieresi‐infected red blood cells, electro ...
erythrocytes, etc ; diabetes; glucose; glycation; glycohemoglobin; hyperglycemia; models; temperature; viscoelasticity; Show all 9 Subjects
Abstract:
... During diabetes, the characteristic hyperglycemia can induce red blood cell glycation. Several researchers have proposed different protocols to perform an in vitro model to study this phenomenon. In this article, some of the most important in vitro glycation protocols available in the bibliography were compared to each other. The incubation parameters as the suspension medium, glucose concentratio ...

Abstract:
... Antifreeze proteins (AFPs) and glycoproteins (AFGPs) are exemplary at modifying ice crystal growth and at inhibiting ice recrystallization (IRI) in frozen solutions. These properties make them highly attractive for cold storage and cryopreservation applications of biological tissue, food, and other water-based materials. The specific requirements for optimal cryostorage remain unknown, but high IR ...
erythrocytes, etc ; Plasmodium falciparum; malaria; merozoites; parasitology; phagocytosis; vaccine development; Show all 7 Subjects
Abstract:
... Protective antibodies against Plasmodium falciparum merozoite antigens, including EBA-175, can inhibit erythrocyte invasion. New data from Musasia et al. indicate that these antibodies can also trigger antibody-dependent phagocytosis of ring-infected and uninfected erythrocytes and that this correlates with protection from malaria. This provides a new pathway for vaccine design. ...

erythrocytes, etc ; Staphylococcus aureus; cell membranes; electron microscopy; hemolysins; transmembrane proteins; Show all 6 Subjects
Abstract:
... Staphylococcus aureus expresses several hemolytic pore‐forming toxins (PFTs), which are all commonly composed of three domains: cap, rim and stem. PFTs are expressed as soluble monomers and assemble to form a transmembrane β‐barrel pore in the erythrocyte cell membrane. The stem domain undergoes dramatic conformational changes to form a pore. Staphylococcal PFTs are classified into two groups: one ...
