Disentangling hydroxynitrile glucoside biosynthesis in a barley (Hordeum vulgare) metabolon provides access to elite malting barleys for ethyl carbamate-free whisky production.

Barley produces several specialized metabolites, including five α-, ß-, and γ-hydroxynitrile glucosides (HNGs). In malting barley, presence of the α-HNG epiheterodendrin gives rise to undesired formation of ethyl carbamate in the beverage production, especially after distilling. Metabolite-GWAS identified QTLs and underlying gene candidates possibly involved in the control of the relative and absolute content of HNGs, including an undescribed MATE transporter. By screening 325 genetically diverse barley accessions, we discovered three H. vulgare ssp. spontaneum (wild barley) lines with drastic changes in the relative ratios of the five HNGs. Knock-out (KO)-lines, isolated from the barley FIND-IT resource and each lacking one of the functional HNG biosynthetic genes (CYP79A12, CYP71C103, CYP71C113, CYP71U5, UGT85F22 and UGT85F23) showed unprecedented changes in HNG ratios enabling assignment of specific and mutually dependent catalytic functions to the biosynthetic enzymes involved. The highly similar relative ratios between the five HNGs found across wild and domesticated barley accessions indicate assembly of the HNG biosynthetic enzymes in a metabolon, the functional output of which was reconfigured in the absence of a single protein component. The absence or altered ratios of the five HNGs in the KO-lines did not change susceptibility to the fungal phytopathogen Pyrenophora teres causing net blotch. The study provides a deeper understanding of the organization of HNG biosynthesis in barley and identifies a novel, single gene HNG-0 line in an elite spring barley background for direct use in breeding of malting barley, eliminating HNGs as a source of ethyl carbamate formation in whisky production.

Mobile Health Technology for the Personalized Therapy of Hemophilia.

The management of patients with hemophilia has evolved significantly since the first treatment attempts were made in the late 1930s. Since then, each new step in the treatment of patients with hemophilia has brought important advancements, as well as its unique set of challenges. Today, a patient-centered, individualized comprehensive approach is the new paradigm, moving away from the traditional "one size-fits-all" approach, to provide the best possible care for each patient with a bleeding disorder. As part of this complex task, mobile health applications might have the capacity to play an important role in reaching that goal. However, the use of new electronic technologies as part of a comprehensive treatment approach for patients with hemophilia simultaneously presents a new set of challenges that needs consideration. In the first section, currently available treatment of hemophilia patients will be revised, while in the second part the role of IT software in the treatment monitoring of hemophilia patients will be discussed.

#Erasmus+ ­ or surgical research, development and innovation at the Department of Surgical Research and Techniques at Semmelweis University / #Erasmus+ - avagy sebészeti kutatás-fejlesztés és innováció a Semmelweis Egyetem Kísérletes és Sebészeti Mutéttani Tanszékén

The European Union is earmarking more and more resources each cycle to support research, development and innovation, and the projects set up by the working groups are helping to develop innovative solutions to reflecting societal issues of today. Since 2014, the Department of Surgical Research and Techniques of the Cardiovascular Center at Semmelweis University has been participating in international consortia supported by the Erasmus+ programme, which aim to modernise the teaching methodology of surgical training and to integrate IT technology into the training of surgical residents at pan-European level. This paper briefly summarises the international projects in which the Department has been involved over the last 7 years.

Solutions for reducing lawsuits in orthopedic surgery by using psychology and IT technology.

Orthopedic surgery is among the top 5 medical specialties with an increased risk of facing a lawsuit. A large part of medical malpractice claims are due to poor communication between physician and patient; therefore, by addressing this issue and implementing psychological methods as well as IT solutions, a reduction in the incidence of medical lawsuits can be achieved. Some of these solutions include implementing and applying psychometric tools such as the SF-36 and SCL-90R tests, creating virtual information hubs for the patient, and establishing efficient communication methods by using IT technology between physician and patient.
