Russian consensus on exoand endocrine pancreatic insufficiency after surgical treatment

The Russian consensus on exo - and endocrine pancreatic insufficiency after surgical treatment was prepared on the initiative of the Russian "Pancreatic Club" on the Delphi method. His goal was to clarify and consolidate the opinions of specialists on the most relevant issues of diagnosis and treatment of exo - and endocrine insufficiency after surgical interventions on the pancreas. An interdisciplinary approach is provided by the participation of leading gastroenterologists and surgeons

Morphological characteristics of experimental ischemic wound healing after application of autoand hetero-fibroblasts and dermal equivalent

Aim. To study morphological structure, collagen synthesis and angiogenesis in biopsy samples of newly formed epidermis and derm on day 19 of their repair in experimental ischemic wound after application of auto- and hetero-fibroblasts as well as after transplantation of dermal equivalent with hetero-fibroblasts. Methods. The study was performed on 28 mature C57/B1 white mice younger than 1 year. Around and into the bed of surgical skin wound in the scapular region, 0.4 ml of suspension of fibroblasts and 1.33 million cells of dermal equivalent were injected. Biopsy sample was embedded in paraffin and was stained with hematoxylin and eosin and by Weigert-Van Gieson. Results. Most importantly, regenerative histogenesis is affected by introduction of auto-fibroblasts, when the greatest thickness of the epidermis is registered and angiogenesis and collagen formation are most active. At the same time, the most differentiated epidermis is observed after transplantation into the wound of dermal equivalent with hetero-bifroblasts. Conclusion. The beneficial effect of dermal equivalent with hetero-bifroblasts differs from the effect of auto-fibroblast suspension by only a few percent: epidermal thickness by 4.29%, the area of collagen fibers by 2.66%, the area of blood vessels by 4.04%, that makes such differences unreliable

Mathematical simulation of heat transfer at deciduous tree ignition by cloud-to-ground lightning discharge

Numerical research results of deciduous tree ignition by cloud-to-ground lightning discharge are presented. The problem is solved in one-dimensional statement in cylindrical system of coordinates. The typical range of influence parameters of positive and negative cloud-to-ground lightning discharges is considered. Ignition conditions for deciduous tree are established

MAST CELLS CONTENT IN THE STRUCTURES OF THE ISCHEMIC MODEL WOUND ON THE 12TH DAY OF REGENERATIVE POTENTIAL STIMULATION BY AUTO- AND HETEROFIBROBLASTS AND DERMAL EQUIVALENT

Mast cell is a traditional cell for wound healing, but their content in the wound after transplantation of autoand heterofibroblasts and dermal equivalent on the basis of these cells remains poorly studied.Aim. To study the morphological structure, collagen formation, angiogenesis and content of mast cells in biopsy materials of the newly formed epidermis and dermis on the 12th day of their recovery in a model ischemic wound after administration of auto- and heterofibroblasts and after transplantation of dermal equivalent with heterofibroblasts.Materials and methods. The study was performed on 28 white mature mice of the C57 / B1 line aged up to 1 year. 0.4 ml of suspension with 1.33 million fibroblasts in growth medium DMEM F12 (Lonza) and in dermal equivalent were administered around and into the bottom of skin surgical model wound in the scapular region. The scar was embedded in paraffin and stained with hematoxylin and eosin, according to Weigert-Van Gieson, and kit for mast cells staining (Biovitrum).Results. On the 12th day epidermis is thicker after introduction of autofibroblasts, but it is more differentiated after transplantation of dermal equivalent with heterofibroblasts. Angiogenesis is also most active after the administration of autofibroblasts. Fibroblasts production of collagen fibers in granulation tissue, angiogenesis and the content of functionally active mast cells indicates the most favorable influence of autofibroblasts transplantation on the wound healing.Conclusion. The effect of dermal equivalent with heterofibroblasts differs from exposure autofibroblasts by several percent: the area of collagen fibers – by 2%, the area of blood vessels − by 5%, the index of degranulation of mast cells – by 4%

Anomalous Diamagnetism of YbPb3YbPb_3 Compound: Pressure Effects

The effect of a uniform pressure on the magnetic susceptibility was measured for $YbPb_3$ compound, wherein a degeneracy point of the energy bands is located just below the Fermi level and responsible for the anomalous diamagnetism. Theoretical analysis of the experimental data has revealed that a pronounced increase of diamagnetism with pressure is governed by closing the degeneracy point towards the Fermi energ
