Acute respiratory distress syndrome (ARDS) is the most common cause of death in COVID-19 patients. The cytokine storm is the main driver of the severity and magnitude of ARDS. Placenta-derived decidua stromal cells (DSCs) have a stronger immunosuppressive effect than other sources of mesenchymal stromal cells. Safety and efficacy study included 10 patients with a median age of 50 (range 14–68) years with COVID-19-induced ARDS. DSCs were administered 1–2 times at a dose of 1 × 106/kg. End points were safety and efficacy by survival, oxygenation and effects on levels of cytokines. Oxygenation levels increased from a median of 80.5% (range 69–88) to 95% (range 78–99) (p = 0.012), and pulmonary infiltrates disappeared in all patients. Levels of IL-6 decreased from a median of 69.3 (range 35.0–253.4) to 11 (range 4.0–38.3) pg/ml (p = 0.018), and CRP decreased from 69 (range 5–169) to 6 (range 2–31) mg/ml (p = 0.028). Two patients died, one of a myocardial infarction and the other of multiple organ failure, diagnosed before the DSC therapy. The other patients recovered and left the intensive care unit (ICU) within a median of 6 (range 3–12) days. DSC therapy is safe and capable of improving oxygenation, decreasing inflammatory cytokine level and clearing pulmonary infiltrates in patients with COVID-19. 相似文献

In this study, length‐length relationships (LLRs) and weight‐length relationships (WLRs) were established for a Carangidae species: Uraspis helvola and tow Flatfishes: Pseudorhombus elevatus and Psettodes erumei that are substantial marine fish species to commercial fisheries in Persian Gulf that are indigenous marine fish species in the region. Samples were collected by non‐selective fish bottom trawler with stretch mesh size of 4 centimeters at the cod‐end area, which helped us to obtain such a broad range size that included small, medium and large size classes during June to August 2017. Hitherto, the length‐weight model presented in this study for Pseudorhombus elevatus and Uraspis helvola were not documented on Fishbase. Additionally, new records of maximum length are presented as 64.5 and 30 centimeters for P. erumei and P. elevatus respectively. A comprehensive size distribution and highly significant fitted model (r2>0.95) in this research provides useful insight for future studies on fish biology, fisheries assessment and ecological modeling. 相似文献

Coronavirus disease 2019 (COVID-19) is the seventh member of the bat severe acute respiratory syndrome family. COVID-19 can fuse their envelopes with the host cell membranes and deliver their genetic material. COVID-19 attacks the respiratory system and stimulates the host inflammatory responses, enhances the recruitment of immune cells, and promotes angiotensin-converting enzyme 2 activities. Patients with confirmed COVID-19 may have experienced fever, dry cough, headache, dyspnea, acute kidney injury, acute respiratory distress syndrome, and acute heart injury. Several strategies such as oxygen therapy, ventilation, antibiotic or antiviral therapy, and renal replacement therapy are commonly used to decrease COVID-19-associated mortality. However, these approaches may not be good treatment options. Therefore, the search for an alternative-novel therapy is urgently important to prevent the disease progression. Recently, microRNAs (miRNAs) have emerged as a promising strategy for COVID-19. The design of oligonucleotide against the genetic material of COVID-19 might suppress virus RNA translation. Several previous studies have shown that host miRNAs play an antiviral role and improve the treatment of patients with COVID-19. miRNAs by binding to the 3′-untranslated region (UTR) or 5′-UTR of viral RNA play an important role in COVID-19-host interplay and viral replication. miRNAs interact with multiple pathways and reduce inflammatory biomarkers, thrombi formation, and tissue damage to accelerate the patient outcome. The information in this review provides a summary of the current clinical application of miRNAs for the treatments of patients with COVID-19. 相似文献

Endometriosis is a multifactorial gynecological condition characterized by the presence of ectopic endometrial and stromal tissue outside the uterus. Free radicals and Oxidative stress have been proposed to be involved in the pathogenesis of the endometriosis. It has been shown that mitochondrial DNA (mtDNA) is particularly susceptible to oxidative damage and mutations due to the high rate of reactive oxygen species production and limited DNA repair capacity in mitochondria. While a number of deletions can occur, the most commonly studied in human is a 4977-bp deletion that removes all or parts of the genes for NADH dehydrogenase subunits 3, 4, 4L and 5, cytochrome C oxidase subunit III and ATP synthase subunits 6 and 8.” We evaluated whether mtDNA common deletion is related with the susceptibility to endometriosis in northern Iran. In this study 80 endometriosis cases and 100 controls were enrolled. Total DNA was extracted from endometrial tissue samples. The mitochondrial common deletion was determined by Gap- polymerase chain reaction (Gap-PCR). It was found that the mitochondrial common deletion was more likely to be present in patients with endometriosis. Assessing indicate that 60 % of patients and 8 % of controls show mtDNA 4977-bp deletion (Odds Ratio [OR] = 17.25, P < 0.0001, confidence interval [CI] = 5.18–57.36). The mtDNA 4977 deletion may play a role in endometriosis. Further studies with larger numbers of patients are required for further evaluation and confirmation of our finding. 相似文献

This study presents length‐weight relationships (LWRs) of Liza klunzingeri (Day, 1888), Cociella crocodilus (Cuvier, 1829), Platycephalus indicus (Linnaeus, 1758) belonging to two Families (Mugilidae and Platycephalidae) from northern coastline of Gulf of Oman (Hormozgan province). Samples were collected by artisanal trawl and beach seine (both with 11 mm effective mesh size) monthly during 2010 to 2015. The presented models were highly significant (p < 0.01) with a reliable coefficient of determination (R2 > 0.90) that provides a reliable basic information for ichthyologists and fisheries scientists. 相似文献

Here we introduce a fast, cost-effective, and highly efficient method for production of soluble fluorescent proteins from bacteria. The method does not require optimization and does not use isopropyl β-d-1-thiogalactopyranoside (IPTG) induction. The method relies on uninduced expression in the BL21–Gold (DE3) strain of Escherichia coli and yields large amounts (up to 0.4 μmol) of fluorescent protein from a 250-ml culture. This method is much simpler than published methods and can be used to produce any fluorescent protein that is needed in biomedical research. 相似文献
