Elastography is based on the estimation of strain due to tissue compression or expansion. Conventional elastography involves computing strain as the gradient of the displacement (time-delay) estimates between gated pre- and postcompression signals. Uniform temporal stretching of the postcompression signals has been used to reduce the echo-signal decorrelation noise. However, a uniform stretch of the entire postcompression signal is not optimal in the presence of strain contrast in the tissue and could result in loss of contrast in the elastogram. This has prompted the use of local adaptive str

Summary. In the postcompression period of crush syndrome regenerative processes develop restorative processes in target organs, in particular in the heart. However, the dynamics of myocardial regenerative changes in the postcompression period in crush syndrome is insufficiently covered in professional literature and requires comprehension study and clarified. The aim of the study – to find out features of regenerative changes in heart of laboratory rats in the dynamics in the postcompression period of crush syndrome. Materials and Methods. Light-optical and polarization were performed examinat

Objective: Crush syndrome (CS) remains a life-threatening condition. This research aims to investigate the changes of the macro- and microelement content in blood, liver and bone tissue in a rat model of CS. Methods Studies were conducted on 40 nonlinear mature white male rats. The left hind limb of the rat was subjected to the mechanical pressure for 4 hours. The compressed area was 4 cm with a compressive 2 2 force of 4.25 kg/cm . Determination of total calcium, magnesium and inorganic phosphate contents in blood serum was performed on a semi-automatic biochemical analyser Humalyzer 2000 (Hu

Ondansetron tablets that are directly compressed using crospovidone and croscarmellose as a synthetic super disintegrant are the subject of this investigation. A central composite, response surface, randomly quadratic, nonblock (version 13.0.9.0) 32 factorial design is used to optimize the formulation (two-factor three-level). To make things even more complicated, nine different formulation batches (designated as F1–F9) were created. There were three levels of crospovidone and croscarmellose (+1, 0, -1). In addition to that, pre- and postcompressional parameters were evaluated, and all evaluat

The current research work involves preparation of fast dissolving tablets of Aceclofenac by direct compression method using different concentrations of Lepidium sativum mucilage as natural superdisintegrant. A two-factor three-level (32) factorial design is being used to optimize the formulation. Nine formulation batches (D1–D9) were prepared accordingly. Two factors as independent variables (X1-amount of β-cyclodextrin and X2-amount of Lepidium sativum mucilage) were taken with three levels (+1,0,-1). The levels of two factors were selected on the basis of preliminary experiments conducted an

Background. Crush syndrome is manifested by the activation of the pituitary-hypothalamic-adrenal system, what is confirmed by a significant increase in the blood levels of catecholamines, cortisol and corticosterone. Its antagonist is the atrial natriuretic peptide, which is synthesized by the myoendocrine cells of the heart, but the question of its participation in the implementation of the adaptation syndrome under the conditions of the postcompression period of crush syndrome remains unresolved. Objective: to establish submicroscopic changes atrial myoendocrynocytes in the early postcompres

La génération d'harmoniques d'ordres élevés est un phénomène physique non linéaire qui se produit en focalisant une impulsion de durée femtoseconde (1 fs = 10⁻¹⁵ s) dans un gaz rare. Elle permet de produire des spectres dans le domaine UV/XUV, se présentant sous forme d'un peigne de fréquences. L'intérêt croissant pour la génération d'harmoniques d'ordres élevés vient du fait que les spectres XUV générés sont compatibles, dans le domaine temporel, avec la production d'impulsions attosecondes (1 as = 10⁻¹⁸ s). Ces impulsions sont d'un grand intérêt dans l'étude de dynamiques électroniques compl
