Until now, the mechanism of tomato genetic male sterility remained unclear. In this study, differential proteomic analysis was performed between genetic male sterile line (2-517), which carries the male sterility (ms1035 ) gene, and its wild type (VF-11) using an isobaric tags for relative and absolute quantification (iTRAQ)-based strategy. A total of 8272 proteins were quantified in the 2-517 and VF-11 lines at the floral bud and florescence stages. These proteins are involved in different cellular and metabolic processes, which express obvious functional tendencies toward the hydroxylation of the ω-carbon in fatty acids, the tricarboxylic acid cycle, the glycolytic and pentose phosphate pathways. Based on our results, a protein network explaining the mechanisms of tomato genetic male sterility was proposed, finding the compromising fat acid metabolism may cause the male sterility. These results were confirmed by parallel reaction monitoring (PRM), qRT-PCR and physiological assays. Taken together, these results provide new insights into the metabolic pathway of anther abortion induced by ms1035 and offer useful clues to identify the crucial proteins involved in genetic male sterility in tomato.

However, this approach still lacks a clearly accepted definition, and the scoping terminology is also somewhat fuzzy. Although the methodology of scoping review processing is relatively uniform, terminological chaos appears in the titles of studies with scoping review methodology. This paper presents an analysis of selected published studies with a focus on the content of their titles. A total of 13 thematic dimensions were identified covering the content of titles that show a degree of inconsistency and frequent terminological and methodological "chaos." This study includes a broad scope of themes and areas for which scoping reviews were produced. We would like to recommend to authors (especially scoping review beginners) to - if not necessary or desirable - avoid introducing new concepts and specifications of titles of produced and published scoping review studies. In the case of literature reviews and knowledge synthesis it is necessary to search according to specific keywords and search phrases - more fragmented scoping review terminology makes literature search more difficult or even impossible. © 2020 John Wiley & Sons Australia, Ltd.BACKGROUND Chronic nasal congestion affects 20% of the population with significant impact on quality of life. This study investigated the simultaneous administration of nasal acoustic vibration and oscillating expiratory pressure for the treatment of nasal congestion. METHODS Patients with chronic nasal congestion but without fixed anatomic obstruction participated in a prospective clinical study applying simultaneous acoustic vibrations and positive expiratory pressure to the nasal cavity twice daily over 5 weeks. Safety was assessed by rhinoscopy and patient questionnaires. Efficacy was assessed using peak nasal inspiratory flow (PNIF), visual analogue scale (VAS) of nasal symptoms, Total Nasal Symptom Score (TNSS), Nasal Obstruction and Septoplasty Effectiveness (NOSE) score, and the 22-item Sino-Nasal Outcome Test (SNOT-22). RESULTS Forty patients (mean age 39 years, 65% female) completed the study with no adverse effects. At the 2 week follow-up, PNIF improved by 25.0 L/min (31% increase from baseline, p less then 0.001). At the 5 week follow-up, nasal congestion VAS improved from mean ± SD of 5.8 ± 2.4 to 2.6 ± 2.3, TNSS improved from 7.2 ± 3.5 to 3.5 ± 3.1, NOSE improved from 50.4 ± 19.9 to 23.3 ± 17.2, and SNOT-22 improved from 31.7 ± 20.3 to 14.2 ± 12.7, all p less then 0.001. Adavosertib purchase Eighty percent of patients would use the device again and 87.5% would recommend to others. CONCLUSION Simultaneous administration of acoustic vibration and oscillating expiratory pressure appears to be a safe treatment for chronic nasal congestion. Results from this initial study are promising with regard to efficacy but will require further study. © 2020 The Authors.

However, an understanding of intrinsic degradation mechanisms of perovskite solar cells (PSCs) containing unreacted PbI2 has been still insufficient and, therefore, needs to be clarified for better operational durability. Here, it is shown that degradation of PSCs is hastened by unreacted PbI2 crystals under continuous light illumination. Unreacted PbI2 undergoes photodecomposition under illumination, resulting in the formation of lead and iodine in films. Thus, this photodecomposition of PbI2 is one of the main reasons for accelerated device degradation. Therefore, this work reveals that carefully controlling the formation of unreacted PbI2 crystals in perovskite films is very important to improve device operational stability for diverse opto-electronic applications in the future. © 2020 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.The rapid pace of progress in implantable electronics driven by novel technology has created devices with unconventional designs and features to reduce invasiveness and establish new sensing and stimulating techniques. Among the designs, injectable forms of biomedical electronics are explored for accurate and safe targeting of deep-seated body organs. Here, the classes of biomedical electronics and tools that have high aspect ratio structures designed to be injected or inserted into internal organs for minimally invasive monitoring and therapy are reviewed. Compared with devices in bulky or planar formats, the long shaft-like forms of implantable devices are easily placed in the organs with minimized outward protrusions via injection or insertion processes. Adding flexibility to the devices also enables effortless insertions through complex biological cavities, such as the cochlea, and enhances chronic reliability by complying with natural body movements, such as the heartbeat. Diverse types of such injectable implants developed for different organs are reviewed and the electronic, optoelectronic, piezoelectric, and microfluidic devices that enable stimulations and measurements of site-specific regions in the body are discussed. Noninvasive penetration strategies to deliver the miniscule devices are also considered. Finally, the challenges and future directions associated with deep body biomedical electronics are explained. © 2020 WILEY-VCH Verlag GmbH & Co.

The aim of this study was to assess the effects on speech and patient-reported experience of palatal augmentation prostheses (PAP) in this patient group. METHODS Twenty consecutive patients who had received a PAP were included. We performed a blinded randomized listener assessment of recordings of the patients' speech with and without the PAP. Patient-reported experiences were collected from medical records. RESULTS The listener assessment showed that production of velar sounds improved significantly for 12 of 19 patients; 12 of 19 patients also reported easier or better speech with the PAP. All six patients treated for tongue cancer reported speech improvement. Seven of 20 patients reported better transport of food or saliva. CONCLUSION A PAP can help patients treated for HNC to more precisely articulated velar consonants and can benefit oral transport. © 2020 The Authors. Head & Neck published by Wiley Periodicals, Inc.Severe asthma imposes a significant burden on individuals, families and the healthcare system. Treatment is complex, due to disease heterogeneity, comorbidities and complexity in care pathways. New approaches and treatments improve health outcomes for people with severe asthma. However, emerging multidimensional and targeted treatment strategies require a reorganisation of asthma care. Consensus is required on how reorganisation should occur and what areas require further research. The Centre of Excellence in Severe Asthma convened 3 forums between 2015 and 2018, hosting experts from Australia, New Zealand and the UK. The forums were complemented by a survey of clinicians involved in the management of people with severe asthma. We sought to 1) identify areas of consensus among experts, 2) define activities and resources required for the implementation of findings into practice and 3) identify specific priority areas for future research. Discussions identified areas of unmet need including assessment and diagnosis of severe asthma, models of care and treatment pathways, add-on treatment approaches and patient perspectives. We recommend development of education and training activities, clinical resources and standards of care documents, increased stakeholder engagement and public awareness campaigns and improved access to infrastructure and funding. Further, we propose specific future research to inform clinical decision-making and develop novel therapies. A concerted effort is required from all stakeholders (including patients, healthcare professionals and organisations and government) to integrate new evidence-based practices into clinical care and to advance research to resolve questions relevant to improving outcomes for people with severe asthma.

Photosensitivity is an increasingly important device performance parameter for nanoscale photodetectors and image sensors, as it determines the ultimate imaging quality and contrast. However, photosensitivities of state-of-the-art low-dimensional nanostructure-based IR detectors are considerably low, limiting their practical applications. Herein, a biomimetic IR detection amplification (IRDA) system that boosts photosensitivity by several orders of magnitude by introducting nanowire field effect transistors (FETs), resulting in a peak photosensitivity of 7.6 × 104 under an illumination of 1342 nm, is presented. Consequently, high-contrast imaging of IR light is obtained on the flexible IRDA arrays. The image information can be then trained and recognized by an artificial neural network for higher image-recognition efficiency. This work provides a new perspective for developing high-performance IR imaging systems, and is expected to undoubtedly enlighten future work on artificial intelligence and biorobotic systems.
