The crystal structure of Cu(dafone)2Cl2, where dafone = 4,5-diazafluoren-9-one was determined to be consisting of unit cells composed of two magnetically unequal centrosymmetric Cu(dafone)2Cl2 molecules. The molecule is a distorted octahedral with a base composed of two nitrogen and two chloride ions in a trans position and apices inhabited by two nitrogen atoms. The significant property of the complex is its coplanar CuN4 coordination in which the strain is relieved by lengthening of a pair of trans Cu-N bonds.

Conditions created by the COVID-19 pandemic have impacted many aspects of medical practice. Responding to this crisis has required health systems to rapidly address a multitude of concerns, including workforce safety, staff redeployment, supply shortages and physical space restructuring. The pace of change created by new information and evolving conditions has proven challenging for traditionally-structured academic departments in medicine. Pandemic medicine requires a nimbleness in decisionmaking, clarity of communication and comprehensiveness of services that may demand a temporary rearrangement of leadership structure and clinical service delivery. Furthermore, the uncertain nature of a pandemic may require reinstitution and dissolution of services as demand sporadically either rises or falls. As the global medical community continues to respond to what may be multiple COVID-19 peaks stretching over months or years, it is important that approaches to preparation and management of the pandemic are shared to enable the identification of best practices and an effective response. With the availability of open access and free communication technologies, these strategies can be easily shared among the global anaesthesia community. The approach outlined here represents one way to organise leadership and streamline communication in order to reinvent an academic department to match the dynamic requirements of crisis conditions. We describe our experience in offering new services such as an airway team, COVID-19 simulation training and personal protective equipment testing, as well as our approach to evaluating the rapid flow of research findings related to SARS-CoV-2 and COVID-19. We summarise lessons learnt and our adaptation to what may be a "new normal" in anaesthesiology practice. [ABSTRACT FROM AUTHOR]

Urologists in the UK are encouraged to follow the National Institute for Health and Care Excellence (NICE) guidelines for patient management. In 2014, members of the British Association of Urological Surgeons (BAUS) were asked in a survey what diagnostic pathway they would follow for themselves or their relatives if they had a raised prostate-specific antigen (PSA). It was found that only a quarter would follow NICE guidance. The current recommendations rely on pathological assessment of prostate tissue obtained at a transrectal ultrasound guided biopsy. Increasing evidence indicates that pre-biopsy multiparametric magnetic resonance imaging (mp-MRI) coupled with targeted biopsy approaches outperform random biopsies in the detection of clinically significant disease. Herein we discuss the role of magnetic resonance imaging and targeted biopsy approaches to diagnose prostate cancer in the modern era. [ABSTRACT FROM AUTHOR]

Introduction Juvenile idiopathic arthritis (JIA) is characterized by a progressive destruction of the joints. The temporomandibular joints (TMJ) are especially likely to be affected. The often undetected arthritis in the TMJ in particular can cause significant destruction and craniofacial developmental abnormalities. The aim of this study was to analyze the destructive impact of JIA on TMJ and mandibular development. Material and methods We analyzed a total of 92 joints and mandibular rami using digital cone-beam tomography (CBT) and compared 23 consecutively treated JIA patients with 23 healthy controls, matched for age and gender. We evaluated ramus length, vertical depth of the articular fossa, anterior–posterior dimensions of the mandibular head and condylar process. The statistical analysis was performed using non-parametric Wilcoxon and Kruskal–Wallis Rank Sum tests. Results The JIA patients exhibited significantly more pronounced asymmetries. However, we were unable to detect significant differences in the metric measuring distances. The different JIA subtypes exerted no statistically significant influence. Conclusions The possible destruction arising as a result of JIA concerns the TMJ and the length of the mandibular ramus. These craniofacial anomalies demonstrate the central importance of sufficiently early detection and timely treatment in the prevention of such growth disturbances. [ABSTRACT FROM AUTHOR]

In this study, the effect of a living bacteria (Bacillus megaterium var. phosphaticum, Azotobacter chroococcum) containing biofertilizer, made in Hungary, was investigated on the germination and dry matter production of maize seedlings in germination tests. The biofertilizer was applied in concentrations of 1 ml·L-1 and 3.5 ml·L-1. Seed and filter paper treatments were used in the experiments, completed with autoclaved biofertilizer treatment. Germination and weight of shoots and roots were evaluated. It was observed that the seed-and-filter paper treatments with biofertilizer significantly increased - by more than 20% - the numbers of the germinated seeds in comparison to the untreated control. The dry weight of the shoot and root was higher by more than 7% than the control in the case of treatments with biofertilizer. Based on this result, it was concluded that there is a positive effect of PGPB on germination, as well as it is supposed, that the applied biofertilizer treatments stimulated the germination and growth of maize by reason of excreting phytohormones and enhancing the nutrient mobilization from the seed.
