Furthermore, the applications of transporter engineering in microbial manufacturing, including enhancement of substrate utilization, concentration of metabolic flux to the target pathway, and acceleration of efflux and recovery of products, demonstrate its outstanding advantages and promising prospects.

Since then, we have been publishing updates as new drugs for hepatitis C become available and new indications for existing drugs are added. The new approval of sofosbuvir/velpatasvir prompted us to publish the seventh version of the guidelines in Japanese in March 2019. We also published the first English-language version of the JSH guidelines in 2013 and English versions of updates made to the Japanese-language guidelines in 2014 and 2016. In 2020, the Committee has decided to publish a new English version, covering general information about treatment for hepatitis C, drugs used, recommended treatments for chronic hepatitis and cirrhosis, and special populations, such as patients who have renal impairment, are on dialysis, or have developed recurrence of hepatitis C after liver transplantation. Furthermore, the Committee has released a separate publication covering the protective effect of antiviral therapy against hepatocarcinogenesis. This article is protected by copyright.

The other common primaries include the breast, kidney, lung, and prostate. Metastasis from the lung to the parotid is a relatively rare occurrence whose exact percentage is not known. Though intralymphatic spread into the parotid is known, intraparenchymal spread through hematogenous route is rare. The presence of intraparenchymal spread of lung Adenocarcinoma to the contralateral parotid diagnosed on fine needle aspiration (FNA) makes it a case worth reporting, highlighting the utility of cell block preparation and immunohistochemistry for a precise and early diagnosis. © 2020 Wiley Periodicals, Inc.We write at the end of the second week in April, a necessary introduction since anything we say about the Covid-19 pandemic may be relevant only for the next few days. That's about the half-life of perceived wisdom in preventing exposure that may give rise to new cases and in providing medical care to existing cases. At the risk of trying to find lessons for the next pandemic while in the midst of the current one, there is much that we have already learned from this one. Weeks ago, in the early stages of the pandemic, several states and localities were at the same point in the pandemic, but have taken dramatically different paths since then. Why? It is the power of exponentiation in which a couple of days can make a huge difference, a geometric difference in prevalence and outcomes. This article is protected by copyright.

This is especially important for biologicals used for treating multiple sclerosis (MS). So far, little is known about whether different information sources report adverse events consistently. METHODS We included biologicals authorised by the European Medicines Agency for the treatment of MS in this study. We compared information on adverse events, derived from the phase three clinical trials, from European public assessment reports (EPARs) and scientific publications. RESULTS In the study, we included eight biologicals used for the treatment of MS for which the EPAR and/or scientific publication reported a total of 707 adverse events. Approximately one-third of the adverse events was reported in both the EPAR and scientific publication, one-third was only reported in the EPAR and one-third only in the scientific publication. Serious adverse events and adverse events that regulators classified as "important identified risk" were significantly more often reported in both sources as compared to adverse events not classified as such (respectively, 38% vs 30% and 49% vs 30%). Adverse events only reported in the EPAR or scientific publication were, in general, not described in the benefit-risk section or abstract, which we considered to be the most important sections of both documents. CONCLUSIONS This study showed that there is substantial discordance in the reporting of adverse events on the same phase three trials between EPARs and scientific publications. To support optimal clinical decision making, both documents should be considered. This article is protected by copyright.

Salinity causes osmotic and ionic stress, inhibiting gas exchange and photosynthesis, ultimately impairing plant growth and development. Arbuscular mycorrhiza (AM) have been shown to maintain light- and carbon use-efficiency under stress, possibly providing a tool to improve salinity tolerance of the host plants. Thus, it was hypothesised that AM will contribute to improved growth and yield under stress conditions. Wheat plants (Triticum aestivum L.) were grown with (AMF+) or without (AMF-) AM fungal inoculation. Plants were subjected to salinity stress (200 mM NaCl) either at pre, post-anthesis, or at both stages. Growth and yield components, leaf chlorophyll content as well as gas exchange parameters and AMF colonisation were analysed. AM plants exhibited a higher rate of net photosynthesis (Pn ) and stomatal conductance (gs ), and lower intrinsic water use efficiency (WUEi ). Furthermore, AM wheat plants subjected to salinity stress at both pre-anthesis and post-anthesis maintained higher grain yield than non-AM salinity-stressed plants. These results suggest that AMF inoculation mitigates the negative effects of salinity stress by influencing carbon-use efficiency and maintaining higher grain yield under stress.
