Influence of corticosterone on the hare's erythrocyte ghosts is studied by the spin-label method. There exists a correlation between the maximal variation region in the rotational diffusion "frequency" of the spin-labels, covalently linked with the membrane protein, and the hormones concentration range within which the effect of corticosterone on the functions of the erythrocyte membranes manifests itself to the greatest degree (permeability to ions, hemolytic effects, etc).

Metallofullerenols and fullerenols have attracted attention due to their remarkable ability to interact with various biologically relevant molecules, paving the way for biomedical applications, ranging from medical imaging techniques to drug carriers, acting with increased efficiency and reduced side effects. In this work, we investigated the effects of two fullerene derivatives, Gd@C(OH) and C(OH), on erythrocyte membrane components under oxidative stress conditions induced by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH) as a source of peroxyl radicals. The results demonstrated that gadolinium encapsulation within the fullerene cage enhanced the electron affinity of Gd@C(OH), resulting in stronger antioxidant activity.

Oxidative stress is widely recognized as a key mechanism in the development of hypertension. Under pathological conditions, such as in hypertension, oxidative stress leads to irreversible posttranslational modifications of proteins, which result in loss of protein function and cellular damage. We have previously documented physiological and morphological changes across various blood and bone marrow cell lineages, all of which exhibit elevated oxidative stress.

Immediately after invading their chosen host cell, the mature human erythrocyte, malaria parasites begin to export an array of proteins to this compartment, where they initiate processes that are prerequisite for parasite survival and propagation, including nutrient import and immune evasion. One consequence of these activities is the emergence of novel adhesive phenotypes that can lead directly to pathology in the human host. To identify parasite proteins involved in this process, we used modern genetic tools to target genes encoding 15 exported parasite proteins, selected by an in silico workflow.
