Asthma associated with obesity is considered the most severe phenotype and can be challenging to manage with standard medications. Marine-derived 1--alkyl-glycerols (AGs), as precursors for plasmalogen synthesis, have high biological activity, making them a promising substance for pharmacology. This study aimed to investigate the effect of AGs from squid on lung function, fatty acid and plasmalogen levels, and cytokine and adipokine production in obese patients with asthma.

The combined course of bronchial asthma (BA) and obesity is one of the urgent medical and social problems that requires a comprehensive and careful study in connection with a decrease in the quality of life of such patients, an increase in the frequency, duration of hospitalization and a high economic burden for the state as a whole. The relationship between BA and obesity is now confirmed by numerous studies, at the same time, despite the variability of the proposed mechanisms of pathogenetic effects of obesity on asthma, metabolic aspects of the relationship of these diseases need further study. Adipose tissue hormones are responsible for the energy homeostasis of the body therefore, excessive accumulation of adipose tissue is accompanied by the development of an imbalance in metabolic processes in various organs and tissues.

Article Synopsis
  • Metabolic syndrome (MetS) is increasingly common globally and is complicated by multiple components, affecting diagnosis and treatment.
  • Insulin resistance, primarily triggered by abdominal obesity, plays a central role in MetS development, with lipids, particularly fatty acids (FAs), significantly influencing insulin signaling and inflammation.
  • A deficiency in n-3 polyunsaturated fatty acids (PUFAs) and an excess of free fatty acids (FFAs) can lead to issues like impaired glucose transport and oxidative stress, highlighting the need for deeper understanding in order to improve diagnostics and therapies for MetS.

The combination of the generic mobile technology and inherent stability, versatility and cost-effectiveness of the synthetic receptors allows producing optical sensors for potentially any analyte of interest, and, therefore, to qualify as a platform technology for a fast routine analysis of a large number of contaminated samples. To support this statement, we present here a novel miniature sensor based on a combination of molecularly imprinted polymer (MIP) membranes and a smartphone, which could be used for the point-of-care detection of an important food contaminant, oestrogen-like toxin zearalenone associated with contamination of cereals. The detection is based on registration of natural fluorescence of zearalenone using a digital smartphone camera after it binds to the sensor recognition element.

The complexity of the pathogenetic mechanisms of the development of chronic inflammation in asthma determines its heterogeneity and insufficient treatment effectiveness. Nuclear transcription factors, which include peroxisome proliferator-activated receptors, that is, PPARs, play an important role in the regulation of initiation and resolution of the inflammatory process. The ability of PPARs to modulate not only lipid homeostasis but also the activity of the inflammatory response makes them an important pathogenetic target in asthma therapy.

Asthma is one of the most important medical and social problems of our time due to the prevalence and the complexity of its treatment. Chronic inflammation that is characteristic of asthma is accompanied by bronchial obstruction, which involves various lipid mediators produced from n-6 and n-3 polyunsaturated fatty acids (PUFAs). The review is devoted to modern ideas about the PUFA metabolites-eicosanoids (leukotrienes, prostaglandins, thromboxanes) and specialized pro-resolving lipid mediators (SPMs) maresins, lipoxins, resolvins, protectins.

Asthma is a common allergic pathology of the respiratory tract that requires the study of mechanisms underlying it, due to severe forms of the disease, which are refractory to therapy. The review is devoted to the search for molecular targets of fatty acid ethanolamides in asthma, in particular palmitoylethanolamide (PEA), which has been successfully used in the treatment of chronic inflammatory and neurodegenerative diseases, in the pathogenesis of which the nervous and immune systems are involved. Recently, the potentially important role of neuro-immune interactions in the development of allergic reactions has been established.

The pathogenesis of age-related diseases such as metabolic syndrome, type 2 diabetes, Parkinson's disease and Alzheimer's disease is associated with oxidative stress and chronic inflammation. Violation of redox homeostasis is accompanied by the development of peroxisome dysfunction and impaired biosynthesis of plasmalogens, which can be closely related to the aging process and the development of age-dependent pathology. Reflecting the functional activity of peroxisomes, plasmalogens can serve not only as potential biomarkers of diseases associated with oxidative stress and aging, but also as an important therapeutic target.

Background: The search for the harmless and effective methods for the drug-free correction of various vegetovascular manifestations associated with the climacteric syndrome (CS) is currently a serious challenge facing modern medicine. Dysfunction of the ovaries during the perimenopause is characterized by the impaired production of sex steroids. The estrogens and progesterone, in their turn, are able to interact with macrophages via the specific receptors of steroid hormones localized on the surface of these cells.

We studied specific effects of different doses of natural minerals--analcime (An) and trepel (Tr)--on the growth rate, selenium (Se) content and functional activity of the genome of wheat leaves measured by the RNA/DNA ratio. Our results show that under the influence of An and Tr, especially at low doses (25 mg/100 g sand), there is a significant increase in the content of Se, increased growth rate of leaves of wheat seedlings and decreased RNA/DNA ratio. We have found significant correlations between studied parameters.

We undertook a structural and functional study of blood cell mitochondria in 25 patients with controlled mild bronchial asthma (BA) including evaluation of blood saturation with oxygen, carboxyhemoglobin level in blood and carbon monoxide content in the exhaled air. Membrane potential of leukocyte mitochondria was determined based on the results of flow cytofluorimetry and fatty acid (FA) composition in platelet mitochondrial membranes measured by GLC. It was shown that the absence of clinical symptoms of BA during remission was associated with a reduction of membrane potential and a change of FA composition resulting in the depletion of the basal pool of saturated (12:0, 14:0, 18:0) and polyunsaturated (20:4n-6, 20:5n-3, 22:5n-3, 22:4n-6) FA.
