Results are reported of a statistical study of the inflammatory processes in the mammary gland, based on data of the biopsy files at the Department of Pathology of the Research Medico-Biological Institute in Sofia for the period 1981-1985. Among 1498 biopsy specimens examined during this period, there were 27 cases of mastitis (1.8 per cent: 5 acute mastitis, 12 chronic diffuse, 10 granulomatous (one of them tuberculous), 2 lipogranulomas and 7 foreign type granulomas. Mean patient age was 45 years. Recognition of nonspecific inflammatory processes in the mammary gland is no problem for the experienced pathologist. Of major important is the evaluation of granulomas with the presence of necrosis, epithelioid and Langhans type giant cells for early diagnosis of such grave disease, as tuberculosis.

Macrocycles or medium-sized rings offer diverse functionality and stereochemical complexity in a well-organized ring structure, allowing them to fulfill various biochemical functions, resulting in high affinity and selectivity for protein targets, while preserving sufficient bioavailability to reach intracellular compartments. These features have made macrocycles attractive candidates in organic synthesis and drug discovery. Since the 20th century, more than three-score macrocyclic drugs, including radiopharmaceuticals, have been approved by the US Food and Drug Administration (FDA) for treating bacterial and viral infections, cancer, obesity, immunosuppression, inflammatory, and neurological disorders, managing cardiovascular diseases, diabetes, and more.

Knee osteoarthritis (KOA) is a prevalent chronic condition characterized by inflammation and oxidative stress, particularly in individuals over 40. Dietary factors, specifically dietary acid load (DAL), may influence these pathological processes. However, the relationship between DAL and inflammatory markers, oxidative stress, and clinical features in patients with KOA remains unexplored.

Pathogen invasion and persistent inflammatory storms caused by bacterial infections are the main challenges to the healing of infected wounds. Herein, this study proposed a pH-responsive polysaccharide hydrogel dressing (CG-HA) composed of cationic guar gum (CG) and hyaluronic acid (HA). Additionally, Zn and ferulic acid (FA)/β-cyclodextrin (β-CD) inclusion complexes (FA/β-CD) were co-introduced into the CG-HA hydrogel to form the desired FA/β-CD@CG-HA-Zn hydrogel.

Microbiota encompasses a diverse array of microorganisms inhabiting specific ecological niches. Gut microbiota significantly influences physiological processes, including gastrointestinal motor function, neuroendocrine signalling, and immune regulation. They play a crucial role in modulating the central nervous system and bolstering body defence mechanisms by influencing the proliferation and differentiation of innate and adaptive immune cells.

Cellular senescence, a hallmark of aging, has emerged as a captivating area of research in tumor immunology with profound implications for cancer prevention and treatment. In the tumor microenvironment, senescent cells exhibit a dual role, simultaneously hindering tumor development through collaboration with immune cells and evading immune cell attacks by upregulating immunoinhibitory proteins. However, the intricate immune escape mechanism of cellular senescence in the tumor microenvironment remains a subject of intense investigation.
