Fungal diversity in the Hyrcanian forests can greatly vary due to diverse ecological conditions. The scope of the present research was to investigate the diversity of wood decay fungi at three sites in the northern forests of Iran. Fruiting bodies of fungi were collected in three plots dominated by Quercus castaneifolia C.A.M. (oak) and Carpinus betulus L. (hornbeam) in the Hyrcanian Forest. As many as 19 and 13 taxa were found on hornbeam and oak, respectively. The identification of these fungi revealed Fomes fomentarius (L.) Fr. and Ganoderma lucidum (Curtis) P. Karst. as highly abundant on hornbeam and oak, respectively. Highest fungal abundance was observed at an altitude range of 1150-1200 meters above sea level. Diversity of macro-fungi was determined and the mean Shannon diversity index was found to be 2.52 and 1.94 for hornbeam and oak, respectively, and mean equitability was calculated as 0.84 and 0.73 for hornbeam and oak, respectively. There were no significant differences in the Shannon Diversity Index or equitability. Overall, current work showed that most of the identified fungi were classified as white rot fungi. 相似文献

BackgroundThe reduction of shoulder dislocation requires adequate procedural sedation and analgesia. The mixture of midazolam and fentanyl is reported in the literature, but long-acting benzodiazepines in conjunction with fentanyl are lacking.Study ObjectiveOur aim was to compar e IV diazepam with IV midazolam in moderate procedural sedation (based on the classification of the American Society of Anesthesiologists) for the reduction of shoulder dislocation.MethodsThis was a randomized controlled clinical trial conducted from April 2019 to December 2019 in the emergency department of a university-affiliated hospital in Tehran, Iran. Participants were adult patients (aged 18–65 years) with anterior shoulder dislocation. Group A (n = 42) received diazepam 0.1 mg/kg plus fentanyl 1 μg/kg IV and group B received midazolam 0.1 mg/kg plus fentanyl 1 μg g/kg IV. Main outcomes measured were onset of muscle relaxation, time taken to reduction, total procedure time, number of the reduction attempts, patient recovery time, the occurrence of the adverse effects, amount of the pain reported by the patients using visual analog scale, and patients and physicians overall satisfaction with the procedure using a Likert scale question.ResultsEighty-one patients were included. The mean ± standard deviation time of the onset of the muscle relaxation and time taken to reduction was shorter in the diazepam plus fentanyl group (p = 0.016 and p = 0.001, respectively). Adverse effects and pain relief were not statistically different between the two groups. Patient recovery time and total procedure time was shorter in the midazolam plus fentanyl group (p = 0.008 and p = 0.02, respectively). The overall satisfaction of patients and physicians was higher in the diazepam plus fentanyl group.ConclusionsAs compared with midazolam plus fentanyl, diazepam plus fentanyl was superior in terms of the onset of the muscle relaxation, patient and physician satisfaction, and time taken to reduction. 相似文献

Despite their indisputable clinical value, current tissue engineering strategies face major challenges in recapitulating the natural nano-structural and morphological features of native bone. The aim of this study is to take a step forward by developing a porous scaffold with appropriate mechanical strength and controllable surface roughness for bone repair. This was accomplished by homogenous dispersion of carbon nanotubes (CNTs) in a poly(lactide-co-glycolide) (PLGA) solution followed by a solvent casting/particulate leaching scaffold fabrication. Our results demonstrated that CNT/PLGA composite scaffolds possessed a significantly higher mechanical strength as compared to PLGA scaffolds. The incorporation of CNTs led to an enhanced surface roughness and resulted in an increase in the attachment and proliferation of MC3T3-E1 osteoblasts. Most interestingly, the in vitro osteogenesis studies demonstrated a significantly higher rate of differentiation on CNT/PLGA scaffolds compared to the control PLGA group. These results all together demonstrate the potential of CNT/PLGA scaffolds for bone tissue engineering as they possess the combined effects of mechanical strength and osteogenicity. 相似文献

IntroductionCOVID-19 is a multi-system infection which predominantly affects the respiratory system, but also causes systemic inflammation, endothelialitis and thrombosis. The consequences of this include renal dysfunction, hepatitis and stroke. In this systematic review, we aimed to evaluate the epidemiology, clinical course, and outcomes of patients who suffer from stroke as a complication of COVID-19.MethodsWe conducted a systematic review of all studies published between November 1, 2019 and July 8, 2020 which reported on patients who suffered from stroke as a complication of COVID-19.Results326 studies were screened, and 30 studies reporting findings from 55,176 patients including 899 with stroke were included. The average age of patients who suffered from stroke as a complication of COVID-19 was 65.5 (Range: 40.4–76.4 years). The average incidence of stroke as a complication of COVID-19 was 1.74% (95% CI: 1.09% to 2.51%). The average mortality of stroke in COVID-19 patients was 31.76% (95% CI: 17.77% to 47.31%). These patients also had deranged clinical parameters including deranged coagulation profiles, liver function tests, and full blood counts.ConclusionAlthough stroke is an uncommon complication of COVID-19, when present, it often results in significant morbidity and mortality. In COVID-19 patients, stroke was associated with older age, comorbidities, and severe illness. 相似文献
