Pathadin (https//gitlab.com/Digipathology/Pathadin) was designed as a WSI oriented open-source set of tools for beginners to experience the advantages of computer-assisted image analysis and cover essential features, frequently strenuous to access with the alternative programs. It is mainly oriented to work with histology slides but also includes a significant part of modern image formats. Introducing Pathadin, the manuscript aims to improve understanding of contemporary image analysis components, resolve technophobia and misbeliefs in the computational field, simplifying pathology research work, and shifting it into a quantitative paradigm. Despite being easy to use, Pathadin includes both basic and advanced analytical algorithms, as the application of machine learning. The functionality of Pathadin is demonstrated by AI-enhanced quantification of epithelial and stromal changes in prostate carcinoma, and their dependence on ISUP grade. The material included 5 radical prostatectomy samples for training and 83rces to experience the advantages of modern computer-assisted analysis.Various cell types participate in the tumor process, in which the mast cells have been described; however, the role they play in colorectal adenocarcinoma has not yet been fully understood. Therefore, the present work aimed to compare employing histochemistry and immunohistochemistry, the number of mast cells and the content of some cytoplasmic granules in moderately differentiated non-metastatic and metastatic colorectal adenocarcinoma, analyzing tissue samples from patients. Histochemical techniques with Toluidine Blue (TBO), Periodic Schiff Acid (PAS), Alcian Blue/Periodic Acid-Schiff (PAB) and Alcian Blue/Safranin (ABS); as well as immunohistochemical reactions with anti-antibodies anti-Tryptase and anti-Chymase were applied to quantify total mast cells and content of some cytoplasmic granules. Statistical analysis was performed using SPSS V22.0 software (p ≤ 0.05). The degree of positivity of the reaction and degranulation of mast cells was reported in percentages. In our results, we observed that there are differences in the quantity and histochemical composition of the granules of mast cells (metastatic group PAS and ABS comparing the TBO reaction), as well as in the immunohistochemical composition between Tryptase and Chymase and the number of degranulated cells in both study groups (74 % degranulated mast cells in the metastatic group, 66 % integrate mast cells in the non-metastatic group). Therefore, we consider that the differences may be some of the probable factors that lead to metastasis of colorectal adenocarcinoma.The purpose of the study was to investigate the effects of ambulatory reloading following hindlimb unloading on the three-dimensional (3D) capillary architecture of rat soleus muscle. In this study, 15 male Sprague-Dawley rats were used. The rats were randomly assigned to the following 3 groups a normal weight bearing control group (CON), 14 days of hindlimb unloading group (HU), and 14 days of hindlimb unloading followed by 7 days of ambulatory reloading group (HU-RL). The capillary diameter and volume were measured using confocal laser microscopy, and capillary number was determined by two-dimensional (2D) capillary staining in the soleus muscle of each group. The capillary diameter and volume as well as the capillary number were significantly lower in the HU group than in the CON group and significantly higher in the HU-RL group than in the HU group. These results provided novel information about the effectiveness of reloading following unloading on not only the 2D increase in capillary number but also the 3D capillary remodeling in the diameter and volume within the unloaded soleus muscle.Leptin is an adipokine that plays an important role in the regulation of energy homeostasis. The failure of endogenous and exogenous leptin to mediate its effects (for example, at suppressing appetite and decreasing body weight) has been
