Efficacy of dispersed fibrous carbon sorbent in treatment of malignant fungating wounds.

Aim: To evaluate the influence of dispersed fibrous carbon sorbent (DFCS) on malignant fungating wounds (MFWs) in Guerin's carcinoma-bearing rats with an assessment of wound bacterial microflora.

Materials And Methods: The study was performed on female Wistar rats inoculated subcutaneously with Guerin T8 carcinoma into the upper interscapular region. On day 20, the tumors were infected by injecting the suspension of S.

Molecular mechanisms of N-acyl homoserine lactone signals perception by plants.

N-acyl homoserine lactones (AHLs) belong to the class of bacterial quorum sensing signal molecules involved in distance signal transduction between Gram-negative bacteria colonizers of the rhizosphere, as well as bacteria and plants. AHLs synchronize the activity of genes from individual cells, allowing the bacterial population to act as a multicellular organism, and establish a symbiotic or antagonistic relationship with the host plant. Although the effect of AHLs on plants has been studied for more than ten years, the mechanisms of plant perception of AHL signals are not fully understood.

Exogenous phytohormones in the regulation of growth and development of cereals under abiotic stresses.

Abiotic stresses, among which extreme temperatures, salinity, drought, UV radiation, heavy metal pollution, etc., adversely affect the growth and yield of cereals, the most important group of monocotyledonous plants that have met the nutritional and other needs of mankind for thousands of years. To cope with stress, plants deploy certain adaptive strategies that combine morphological, physiological, and biochemical responses, and on which growth and productivity depend.

Molecular mechanisms of plant adaptive responses to heavy metals stress.

Heavy metals (HMs) are among the main environmental pollutants that can enter the soil, water bodies, and the atmosphere as a result of natural processes (weathering of rocks, volcanic activity), and also as a result of human activities (mining, metallurgical and chemical industries, transport, application of mineral fertilizers). Plants counteract the HMs stresses through morphological and physiological adaptations, which are imparted through well-coordinated molecular mechanisms. New approaches, which include transcriptomics, genomics, proteomics, and metabolomics analyses, have opened the paths to understand such complex networks.

Can tailored nanoceria act as a prebiotic? Report on improved lipid profile and gut microbiota in obese mice.

Background: Microbiome modulation is a pillar intervention to treat metabolic syndrome, prestages, and cascade of related pathologies such as atherosclerosis, among others. and probiotic strains demonstrate efficacy to reduce obesity, dyslipidemia, and improve metabolic health. Novel prebiotic substances composed with known probiotics may strongly synergize health benefits to the host.
