Ergoline alkaloids (syn. ergot alkaloids) are constituents of clavicipitaceous fungi (Ascomycota) and of one particular dicotyledonous plant family, the Convolvulaceae. While the biology of fungal ergoline alkaloids is rather well understood, the evolutionary and biosynthetic origin of ergoline alkaloids within the family Convolvulaceae is unknown. To investigate the possible origin of ergoline alkaloids from a plant-associated fungus, 12 endophytic fungi and one epibiotic fungus were isolated from an ergoline alkaloid-containing Convolvulaceae plant, Ipomoea asarifolia Roem. & Schult. Phylogenetic trees constructed from 18S rDNA genes as well as internal transcribed spacer (ITS) revealed that the epibiotic fungus belongs to the family Clavicipitaceae (Ascomycota) whereas none of the endophytic fungi does. In vitro and in vivo cultivation on intact plants gave no evidence that the endophytic fungi are responsible for the accumulation of ergoline alkaloids in I. asarifolia whereas the epibiotic clavicipitaceous fungus very likely is equipped with the genetic material to synthesize these compounds. This fungus resisted in vitro and in vivo cultivation and is seed transmitted. Several observations strongly indicate that this plant-associated fungus and its hitherto unidentified relatives occurring on different Convolvulaceae plants are responsible for the isolated occurrence of ergoline alkaloids in Convolvulaceae. This is the first report of an ergot alkaloid producing clavicipitaceous fungus associated with a dicotyledonous plant.

The Newborn Hearing Screening Program has existed in Poland for almost 20 years. However, for the first time in the history of his activity, he had to deal with large logistic and staffing problems. The analysis compared the years 2020 and 2021 in terms of the functioning of centers that conduct audiological diagnostics of the Program during the Covid-19 pandemic. In order to obtain relevant information, a telephone survey was conducted at the beginning of 2022 with questions about the performance of standard activities related to the Program. Results In 2020, 60 centers conducting audiological diagnostics (66.67%) were suspended, and 30 were working under the sanitary and epidemiological regime (33.33%). In 2021, only 5 (5.26%) diagnostic centers with their headquarters in facilities transformed into so-called homonymous hospitals, dealing only with the treatment of patients infected with SARS-CoV-2 virus, were suspended. Discussion The development of the pandemic and the related limitations around the world had a significant impact on the quality and scope of medical services provided. Many hospitals were quickly transformed into closed centers treating only patients with SARS-CoV-2. Audiological consultations take place in closed, soundproof rooms. Face-to-face contact was required for hearing assessment, fitting hearing aids, troubleshooting, and rehabilitation. The COVID-19 pandemic has forced audiology to modify existing practices. The use of telemedicine was increasingly preferred. In Poland, as all over the world, the scope of remote consultations has expanded, but due to technological and hardware limitations, audiological procedures remained in the sphere of direct contact with the patient. Conclusions In the first year after the announcement of the pandemic, significant difficulties were observed in the functioning of centers dealing with the diagnosis of children with suspected hearing loss. The appearance of the SARS-CoV-2 virus forced us to develop innovative methods of early diagnosis and treatment of children with hearing impairment, which resulted in the stabilization of the work of individuals in the following year.

THE INTERFACE IS WHERE the interactive dimensions of new technologies actually occur. As user choices become more numerous and as businesses insist on efficient pathways through these options, interface design has emerged as a critical aspect of contemporary product development. Here, Alec Bernstein, Laura Robin, and Monika Zych describe how their Advanced Communications Group makes use of experts in musical composition, painting, and literature, as well as software and electrical engineering, to devise effective interface solutions.
