Regional blood flow and intensity of free-radical lipid peroxidation were evaluated at rheogastrography and biochemically (quantitation of malonic dialdehyde and antioxidant serum activity), respectively, in 25 patients with recurrent ulcer. Recurrent ulcer is shown to induce disturbances in gastric wall regional hemodynamics due to activated vascular tone, reduced arterial blood inflow and venostasis. Lipid peroxidation became overactive and decreased defence potentialities of gastroduodenal serum. Oleum Hippopheae which is a natural antioxidant, improves regional hemodynamics by relaxation of overstrained vessels, stimulation of arterial blood inflow and relief of venous congestion. Overactive lipid peroxidation declines, antioxidant activity of the serum improves, especially in gastric ulcer, ulcer defect repair runs more actively.

The increasing level of cadmium (Cd) contamination in soil due to anthropogenic actions is a significant problem. This problem not only harms the natural environment, but it also causes major harm to human health via the food chain. The use of chelating agent is a useful strategy to avoid heavy metal uptake and accumulation in plants.

Axonal fusion represents an efficient way to recover function after nerve injury. However, how axonal fusion is induced and regulated remains largely unknown. We discover that ferroptosis signaling can promote axonal fusion and functional recovery in C.

Ferroptosis is a novel, iron-dependent form of non-apoptotic cell death characterized by the accumulation of lipid reactive oxygen species (ROS) and mitochondrial shrinkage. It is closely associated with the onset and progression of various diseases, especially cancer, at all stages, making it a key focus of research for developing therapeutic strategies. Numerous studies have explored the role of microRNAs (miRNAs) in regulating ferroptosis by modulating the expression of critical genes involved in iron metabolism and lipid peroxidation.

Antarctica has one of the most sensitive ecosystems to the negative effects of Persistent Organic Pollutants (POPs) on its biodiversity. This is because of the lower temperatures and the persistence of POPs that promote their accumulation or even biomagnification. However, the impact of POPs on vascular plants is unknown.

Human allele variants that encode proteins differing only in the number of cysteine (Cys)-to-arginine (Arg) exchanges (ApoE2 [2 Cys], ApoE3 [1 Cys], ApoE4 [0 Cys]) comprise the strongest genetic risk factor for sporadic Alzheimer's disease (AD); however, the molecular feature(s) and resultant mechanisms that underlie these isoform-dependent effects are unknown. One signature feature of Cys is the capacity to form disulfide (Cys-Cys) bridges, which are required to form disulfide bridge-linked dimers and multimers.
