    The Atlantic killifish (Fundulus heteroclitus) is an environmental sentinel organism used extensively for studies on environmental toxicants and salt (NaCl) homeostasis. Previous research in our laboratory has shown that rapid acclimation of killifish to seawater is mediated by trafficking of CFTR chloride channels from intracellular vesicles to the plasma membrane in the opercular membrane within the first hour in seawater, which enhances chloride secretion into seawater, thereby contributing to salt homeostasis. Acute transition to seawater is also marked by an increase in both mRNA and protein levels of serum glucocorticoid kinase 1 (SGK1) within 15 minutes of transfer. Although the rise in SGK1 in gill and its functional analog, the opercular membrane, after seawater transfer precedes the increase in membrane CFTR, a direct role of SGK1 in elevating membrane CFTR has not been established in vivo. To test the hypothesis that SGK1 mediates the increase in plasma membrane CFTR we designed two functionally different vivo-morpholinos to knock down SGK1 in gill, and developed and validated a vivo-morpholino knock down technique for adult killifish. Injection (intraperitoneal, IP) of the splice blocking SGK1 vivo-morpholino reduced SGK1 mRNA in the gill after transition from fresh to seawater by 66%. The IP injection of the translational blocking and splice blocking vivo-morpholinos reduced gill SGK1 protein abundance in fish transferred from fresh to seawater by 64% and 53%, respectively. Moreover, knock down of SGK1 completely eliminated the seawater induced rise in plasma membrane CFTR, demonstrating that the increase in SGK1 protein is required for the trafficking of CFTR from intracellular vesicles in mitochondrion rich cells to the plasma membrane in the gill during acclimation to seawater. This is the first report of the use of vivo-morpholinos in adult killifish and demonstrates that vivo-morpholinos are a valuable genetic tool for this environmentally relevant model organism

    Objective: to evaluate the expression levels of miRNA (miR-27, miR-101, miR-142, miR-339 and miR-424) and its relationship with clinical and laboratory parameters in lung transplant recipients. Materials and methods. The study included 57 lung recipients aged 10 to 74 years (35 Β± 15), including six children (9%) – four boys 10, 12, 13 and 17 years and girls 13 and 14 years old – and 51 adult recipients, including 30 men (62.5%). The control group was made up of 14 healthy individuals that were not significantly different by gender and age. Expression levels of the microRNAs studied in blood plasma were determined via quantitative polymerase chain reaction (PCR). Correlations of miRNA expression levels with complete blood count and biochemical blood test indicators were analyzed. Results. Patients with end-stage chronic respiratory failure (potential lung recipients) were found to have significantly higher expression levels of miR-27, miR-101 and miR-339 in plasma than the healthy individuals (p = 0.02, p = 0.03 and p = 0.01, respectively). The expression level of miR-339 correlated with the age of potential lung recipients (p = 0.04). It was a negative correlation (r = –0.46). The expression levels of the other four miRNAs were age independent. The average expression level of miR-424 in lung recipients in the long-term period after lung transplant was higher than in waitlisted patients (p = 0.03). Analysis of the relationship between miRNA expression levels and external respiration function in the long-term post-transplant period showed that miR-142 expression level (r = 0.61; p = 0.04) positively correlates with the Tiffeneau-Pinelli index. This strong correlation, which exceeds 85%, indicates the presence of restrictive lung diseases. A year and more after transplantation, it was found that in the recipients, there were close positive correlations between miR-27, miR-142, miR-424 expression levels and blood leukocyte concentration, as well as between the miR-142 expression level and the sCD40L concentration during this period. Conclusion. A comparative study of the expression level of miRNAs (miR-27, miR-101, miR-142, miR-339 and miR-424) in the blood plasma of patients suffering from end-stage chronic lung diseases of various origin and in lung recipients enables us to conclude that further studies of the miRNA panels are needed in order to assess their effectiveness as potential molecular and genetic markers of post-transplant complications.ЦСль: ΠΎΡ†Π΅Π½ΠΈΡ‚ΡŒ ΡƒΡ€ΠΎΠ²Π΅Π½ΡŒ экспрСссии ΠΌΠΈΠΊΡ€ΠΎΠ ΠΠš (miR-27, miR-101, miR-142, miR-339 ΠΈ miR-424) ΠΈ Π΅Π΅ связь с клиничСскими ΠΈ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹ΠΌΠΈ ΠΏΠ°Ρ€Π°ΠΌΠ΅Ρ‚Ρ€Π°ΠΌΠΈ Ρƒ Ρ€Π΅Ρ†ΠΈΠΏΠΈΠ΅Π½Ρ‚ΠΎΠ² трансплантированных Π»Π΅Π³ΠΊΠΈΡ….

    Lung transplantation is the final treatment option for end-stage lung failure. In 2019, 63,530 lung transplants wereΒ performed worldwide [13]. Due to the variety of diseases causing patients to resort to lung transplant surgeries,Β there is a wide range of different complications and conditions that are subject to an individual clinical approachΒ to determine treatment tactics. Each case is of great clinical interest due to the small amount of these operationsΒ and the complexity of postoperative rehabilitation, which requires a multidisciplinary approach [12]. We present aΒ report on a surgical treatment of expiratory tracheal stenosis in combination with bronchiectasis in a lung recipient.Врансплантация Π»Π΅Π³ΠΊΠΈΡ… – СдинствСнный Ρ€Π°Π΄ΠΈΠΊΠ°Π»ΡŒΠ½Ρ‹ΠΉ ΠΌΠ΅Ρ‚ΠΎΠ΄ лСчСния Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ Π»Π΅Π³ΠΊΠΈΡ… Π² Ρ‚Π΅Ρ€ΠΌΠΈΠ½Π°Π»ΡŒΠ½ΠΎΠΉΒ ΡΡ‚Π°Π΄ΠΈΠΈ Π΄Ρ‹Ρ…Π°Ρ‚Π΅Π»ΡŒΠ½ΠΎΠΉ нСдостаточности.

    Bronchial complications, along with development and progression of chronic dysfunction on the background of chronic rejection, are factors that reduce the quality and life of lung and heart-lung recipients. They also increase the frequency of hospitalizations. Application of cryotechnology is based on the contact effect of extremely low temperatures on organs and tissues using a cryoprobe. This article demonstrates the experience of using cryotechnology in the diagnosis and treatment of complications in lung and heart-lung recipients.Π‘Ρ€ΠΎΠ½Ρ…ΠΈΠ°Π»ΡŒΠ½Ρ‹Π΅ ослоТнСния наряду с Ρ€Π°Π·Π²ΠΈΡ‚ΠΈΠ΅ΠΌ ΠΈ прогрСссированиСм хроничСской дисфункции Π½Π° Ρ„ΠΎΠ½Π΅ хроничСского отторТСния ΡΠ²Π»ΡΡŽΡ‚ΡΡ Ρ„Π°ΠΊΡ‚ΠΎΡ€Π°ΠΌΠΈ, ΡΠ½ΠΈΠΆΠ°ΡŽΡ‰ΠΈΠΌΠΈ качСство ΠΈ ΠΏΡ€ΠΎΠ΄ΠΎΠ»ΠΆΠΈΡ‚Π΅Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ ΠΆΠΈΠ·Π½ΠΈ Ρ€Π΅Ρ†ΠΈΠΏΠΈΠ΅Π½Ρ‚ΠΎΠ² Π»Π΅Π³ΠΊΠΈΡ… ΠΈ сСрдСчно-Π»Π΅Π³ΠΎΡ‡Π½ΠΎΠ³ΠΎ комплСкса, Π° Ρ‚Π°ΠΊΠΆΠ΅ ΡƒΠ²Π΅Π»ΠΈΡ‡ΠΈΠ²Π°ΡŽΡ‰ΠΈΠΌΠΈ частоту госпитализаций.

    Objective: to evaluate the expression levels of miRNA (miR-27, miR-101, miR-142, miR-339 and miR-424) and its relationship with clinical and laboratory parameters in lung transplant recipients. Materials and methods. The study included 57 lung recipients aged 10 to 74 years (35 Β± 15), including six children (9%) – four boys 10, 12, 13 and 17 years and girls 13 and 14 years old – and 51 adult recipients, including 30 men (62.5%). The control group was made up of 14 healthy individuals that were not significantly different by gender and age. Expression levels of the microRNAs studied in blood plasma were determined via quantitative polymerase chain reaction (PCR). Correlations of miRNA expression levels with complete blood count and biochemical blood test indicators were analyzed. Results. Patients with end-stage chronic respiratory failure (potential lung recipients) were found to have significantly higher expression levels of miR-27, miR-101 and miR-339 in plasma than the healthy individuals (p = 0.02, p = 0.03 and p = 0.01, respectively). The expression level of miR-339 correlated with the age of potential lung recipients (p = 0.04). It was a negative correlation (r = –0.46). The expression levels of the other four miRNAs were age independent. The average expression level of miR-424 in lung recipients in the long-term period after lung transplant was higher than in waitlisted patients (p = 0.03). Analysis of the relationship between miRNA expression levels and external respiration function in the long-term post-transplant period showed that miR-142 expression level (r = 0.61; p = 0.04) positively correlates with the Tiffeneau-Pinelli index. This strong correlation, which exceeds 85%, indicates the presence of restrictive lung diseases. A year and more after transplantation, it was found that in the recipients, there were close positive correlations between miR-27, miR-142, miR-424 expression levels and blood leukocyte concentration, as well as between the miR-142 expression level and the sCD40L concentration during this period. Conclusion. A comparative study of the expression level of miRNAs (miR-27, miR-101, miR-142, miR-339 and miR-424) in the blood plasma of patients suffering from end-stage chronic lung diseases of various origin and in lung recipients enables us to conclude that further studies of the miRNA panels are needed in order to assess their effectiveness as potential molecular and genetic markers of post-transplant complications

    Lung transplantation (LT) for idiopathic pulmonary arterial hypertension (IPAH) now is the only radical treatment of this disease.Aim: to analyze own experience of performing LT in patients with IPAH.Materials and methods. 8 adult IPAH patients, who underwent LT between 2014 and october 2018, were included. In 7 of 8 patients undergoing bilateral lung transplantation on intraoperative venoarterial extracorporeal membrane oxygenation (VA ECMO) with prolongation into the postoperative period.Results. VA ECMO support was prolonged into postoperative period 6 and 7 days respectively in 2 (25,0%) patients and 3 days in 6 (75,0%) patients. Hospital mortality in IPAH patients was 1.Conclusions. Own experience demonstrates that LT is an effective method of treatment in patients with IPAH. Hospital, 1- and 3-year survival rates for the patient collective were 87.5, 75.0 and 75.0% respectively
