It was found that hydrophobic interactions, along with hydrogen-bonding via the imidazole nitrogen heteroatom, promoted interactions with the Aβ peptide, thereby limiting its aggregation. Furthermore, it was found that having rapid and sequential exchange proved detrimental as it resulted in a decreased association with Aβ. These results highlight important considerations between a balance of intermolecular interactions and ligand exchange kinetics in the design of further therapeutic candidates.As one of the most frequent diabetic complications, diabetic foot ulcer (DFU) can cause limb ischemia or even amputation. Paeoniflorin (PF) has been reported to possess many kinds of biological functions, such as antioxidant and anti-inflammatory effects. However, the role of PF in DFU remains unknown. In this study, streptozotocin (STZ)-induced diabetic rat models and high glucose (HG)-treated Human immortalized keratinocytes (HaCaT) cells were established. Histological analysis, immunohistochemistry, Electrophoretic mobility shift assay, MTT assay, TUNEL assay, oxidative stress analysis, ELISA assay and western blot were used to investigate the role and underlying mechanisms of PF on healing in DFU. Our results showed that the STZ-induced diabetic rats had delayed wound healing compared with the normal rats, exhibited by intense oxidative DNA damage, low vascular endothelial growth factor (VEGF) and transforming growth factor β1 (TGF-β1) expression, as well as increased apoptosis. PF treatment activated the expression of nuclear factor-E2-related factor 2 (Nrf2) and improved wound healing in DFU rats. Our in vitro experiments confirmed that PF accelerated wound healing through the Nrf2 pathway under hyperglycemic conditions, with alleviated oxidative stress, increased cell proliferation and migration, decreased apoptosis, and increased the expression of VEGF and TGF-β1. Our study demonstrates the therapeutic benefits of PF in diabetic wound healing, which provides a reference for future clinical trials using PF in DFU treatment.

Based on the high incidence of thromboembolic events (TEs) observed in lung adenocarcinomas with ALK translocations and taking into account the biological proximity of ROS1 and ALK, we conducted a retrospective analysis of patients with advanced lung carcinoma carrying rearrangements in ROS1 from 23 centres in Spain and one centre in Portugal.

The main objective of the study was to analyse the incidence of TE in this population, looking for predictive risk factors, and its impact on overall survival.

A total of 58 patients were included. The incidence of TEs throughout the disease was 46.6% (n=27) with a median follow-up of 19 months (range 1-78 months) and a median overall survival of 52 months in the total population and 50 months for the patients presenting TEs, with a hazards ratio of 1.12 (95% confidence interval 0.47-2.65) p=0.78. The majority of the events were venous (n=24; 89%) and occurred in the ambulatory setting (n=18; 67%). Almost half of the patients (n=13; 48%) presented the TE in the peri-diagnostic period.

The high incidence of thrombosis, especially during the cancer diagnosis process, requires special attention from a clinician. Despite the limitations of such a small descriptive study, its results are in accordance with previously reported data. It would be important to design prospective studies of antithrombotic prophylaxis in this population because of their possible impact in reducing the risk of TEs.

We examined the actionable genomic alterations in ovarian cancer by analysing the nationwide registry of next-generation sequencing (NGS) data.

From March 2017 to December 2018, 16,458 patients with cancer underwent NGS testing under the interim coverage programme for NGS provided by the National Health Insurance of Korea. Among these patients, 779 patients had advanced ovarian cancer. Fifty-eight mutations were reported as pathogenic variants, which included likely pathogenic variants, and 55 theoretically actionable genes were analysed.

The prevalence of pathogenic mutations in the population was 81.5%, whereas 11.6% of the population had neither a pathogenic mutation nor a variant of unknown significance. Common pathogenic mutations shared by at least 3% of the study population were mutations in TP53 (61.5%), BRCA1 (12.2%), PIK3CA (10.4%), KRAS (10.3%), BRCA2 (9.6%)and PTEN (3.7%). BRCA1/2 pathogenic mutations were found in 14.0% (42 of 300, 95% confidence interval = 10-18%) of the patients with TP53 wild-type tumours, comprising approximately one-quarter (25.9%) of the total observed BRCA1/2 pathogen mutations. At least one pathogenic mutation in a theoretically actionable gene was found in 49.2% of patients. Among patients without a BRCA1/2 pathogenic mutation, mutations were frequently observed in KRAS (12.2%), PIK3CA (10.4%)and PTEN (4.2%). PTCH1 mutations were correlated with ATM, NF1, ERBB2 and MTOR mutations (adjusted p=0.0054, p=0.0035, p=0.0010and p=0.0003, respectively).

Almost half of patients with ovarian cancer could be estimated as theoretical candidates for genomic medicine. Substantial BRCA1/2 pathogenic mutations were observed in patients not harbouring a TP53 mutation.

Bone conduction hearing devices are a well-established treatment option for conductive or mixed hearing losses as well as single-sided deafness. The Osia® 2 System is an active osseointegrated device where a surgically implanted titanium fixture supports a newly developed piezoelectric actuator that is placed under the skin.

Nationwide data collected during a controlled-market release (CMR) of the Cochlear™ Osia® 2 System as well as outcomes at single, tertiary-level private practice Otology/Neurotology center were retrospectively reviewed. Key learnings from surgeons and audiologists are discussed.

During the CMR period, 23 surgeons performed 44 operations on 43 recipients. The mean age of recipients was 44years and mean surgery duration was 52min. The most commonly used incision was postauricular but anterior to the device (78%). SY-5609 Five complications were observed during the CMR, none of which were device related. Twenty-one audiologists performed 33 Osia® 2 activations during the CMR. The mean age of this group was 47years, and the mean duration of each activation appointment was 55min.
