Identification at these levels can be improved by more inclusive reference libraries. Using the 18S mini-barcode and the reference library, we recovered eDNA from 21 marine macrophytes in sediments, demonstrating the barcode's ability to trace primary producers that contribute to blue carbon. We expect this barcode to also be useful for other ecological questions, such as tracing macro primary producers in marine food webs. This article is protected by copyright.

It is difficult to apply traditional spray treatments directly onto the plant stems due to the blocking agent produced by leaves. Further, spiders and mirids, the natural enemies of N. lugens (Stal), are directly exposed to the chemicals during spraying. Sulfoxaflor-loaded natural polysaccharide microspheres with good performance were developed and tested in rice fields. The absorption, distribution, and dissipation of sulfoxaflor in rice plants, soil, and water were examined. RESULTS Sulfoxaflor-loaded natural polysaccharide microspheres were prepared through physical embedding and ionic crosslinking, using citronellol as an oil phase to provide float. The sustained release of sulfoxaflor was achieved through swelling and dissolution, indicating that these structures could effectively control pesticide release. click here Field experiments showed that these microspheres were able to float in water and gather around the stem of rice plants and that their insecticidal effect was remarkably improved compared to that achieved using the suspension concentrate. Results also showed that the residual content of stems following treatment with sulfoxaflor-loaded natural polysaccharide microspheres reached 0.331 mg/kg, but was reduced in other parts of the plant. CONCLUSION In the present study, sulfoxaflor-loaded natural polysaccharide microspheres with optimized properties were successfully prepared. These microspheres produced a better control effect on N. lugens (Stal) compared to the use of the sulfoxaflor suspension concentrate. Their application may help promote the scientific control of target pests in rice fields. This article is protected by copyright. All rights reserved. This article is protected by copyright.

We sought to use Google Trends (GT) to investigate whether there was a surge in individuals searching for information related to smell loss during the COVID-19 epidemic in the Italy, Spain, UK, USA, Germany, France, Iran and Netherlands. METHODS GT was used to explore Internet activity related to loss of smell in Italy, Spain, UK, USA, Germany, France, Iran and Netherlands. Spearman rank analysis was performed to correlate loss of smell relative search volumes (RSV) with the increases of daily confirmed cases of COVID-19 and deaths attributed to disease. As a control event, we also performed analysis of smell-related searches during the last UK Influenza epidemic of 2009. RESULTS In all three countries, we observed strong correlations between daily RSVs related to loss of smell, increases of daily COVID-19+ cases and deaths ranging from 0.633 to 0.952. All correlations were statistically significant (p less then 0.05). CONCLUSION There is a strong correlation between the frequency of searches for smell-related information and the onset of COVID-19 infection in Italy, Spain, UK, USA, Germany, France, Iran and Netherlands. We would hypothesise this may relate to a previously under-recognised symptom. This article is protected by copyright. All rights reserved. This article is protected by copyright.

BACKGROUND To evaluate and compare the prediction accuracy of IOL power calculation methods after previous laser refractive surgery using standard keratometry (SK), measured posterior corneal astigmatism (PCA) and total keratometry (TK). DESIGN Retrospective consecutive cohort. PARTICIPANTS 50 consecutive patients (72 eyes) at a private institution who underwent cataract surgery with prior laser refractive procedures. METHODS Methods using SK included ASCRS mean, Barrett True K no history, Haigis-L and Shammas IOL formulae. Barrett True K using posterior values (True K TK), Haigis and Holladay 1 Double-K methods using TK were also assessed. Post-surgery refraction was undertaken at minimum 3 weeks following surgery. MAIN OUTCOME MEASURES Arithmetic and absolute IOL refractive prediction errors, variances in mean arithmetic IOL prediction error, and percentage of eyes within ±0.25D, ± 0.50D, ± 0.75D and ± 1.00D of refractive prediction errors were compared. RESULTS The Barrett True K (TK) provided the lowest mean refractive prediction error and variance for both prior myopes and hyperopes undergoing cataract surgery. The Barrett True K (TK) exhibited the highest percentages of eyes within ±0.50D, ± 0.75D and ± 1.00D of the refractive prediction error compared to other formulae for prior myopic patients. CONCLUSIONS AND RELEVANCE Accuracy of IOL power calculations in post-laser eyes can be improved by the addition of posterior corneal values as measured by the IOLMaster 700. The use of total keratometry may supplement outcomes when no prior refraction history is known. This article is protected by copyright. All rights reserved. This article is protected by copyright.

HEV infection could progress to chronic infection in an immunosuppressed host. De novo autoimmune hepatitis (AIH) is a rare occurrence of AIH during post-LT immunosuppressive therapy in patients who underwent LT due to not AIH but some other etiology. Here, we report the first case of ALF due to HEV infection, the recurrence of HEV after LT that responded to ribavirin therapy, and then the development of de novo AIH showing a complete response to glucocorticoid therapy but multiple relapses after steroid withdrawal. This peculiar case suggests that HEV could have a pathogenic role in the development of the de novo AIH; additionally, this case report could help clinicians make therapeutic decisions in the post-LT condition. © 2020 John Wiley & Sons A/S.
