Sex Med 2021;9100290.Yellowhorn (Xanthoceras sorbifolium Bunge) is a woody oil species that is widely distributed in northwestern China. To investigate the molecular mechanisms underlying the drought and heat tolerance response of yellowhorn seedlings, changes in protein abundance were analyzed via comparative proteomics. Drought and heat treatment of seedlings was applied in growth chamber, and the leaves were harvested after 7 days of treatment. The total protein was extracted, and comparative proteomic analysis was performed via isobaric tag for relative and absolute quantitation (iTRAQ). The abundance of most of the proteins associated with oxidative phosphorylation, NADH dehydrogenase and superoxide dismutase (SOD) was reduced. Tyrphostin B42 chemical structure The differential proteins associated with photosynthesis enzymes indicated that stress had different effects on photosystem I (PSI) and photosystem II (PSII). After comprehensively analyzing the results, we speculated that drought and heat stress could hinder the synthesis of riboflavin, reducing NADH dehydrogenase content, which might further have an impact on energy utilization. Yellowhorn seedlings relied on Fe-Mn SOD enzymes rather than Cu/Zn SOD enzymes to remove reactive oxygen species (ROS). In addition, heat-shock proteins (HSPs) had significant increase and played a key role in stress response, which could be divided into two categories according to their transcription and translation efficiency. Over all, the results can provide a basis for understanding the molecular mechanism underlying resistance to drought and heat stress in yellowhorn and for subsequent research of posttranslational modification-related omics of key proteins.The CRISPR/Cas9-based targeted genome editing has emerged as a versatile technique, widely employed in plant genome engineering, both to decipher gene function and as an alternative to classical breeding technique for traits improvement in plants. However, to date, no such platform has been developed for hop (Humulus lupulus L.), which is an economically important crop producing valuable secondary metabolites utilized in the brewing and pharmaceutical industries. Here, we present the first report on the successful establishment of efficient CRISPR/Cas9-based genome editing using the visible endogenous marker gene phytoene desaturase (PDS) involved in carotenoid biosynthesis to demonstrate successful genome editing in hop. Agrobacterium tumefaciens-mediated transformation of in vitro generated internodal explants was used for the stable integration of constructs expressing plant codon-optimized Cas9 and a pair of co-expressed guide RNAs to target the distinct genomic sites of the PDS gene of hop. Analysis of RNA-guided genome-editing events, including mutant lines screening and homozygosity assessment using the T7 endonuclease assay showed that 33.3% of transformed plants were successfully edited at the target site, displaying albino and mosaic regenerants. Intriguingly, the detected mutations were ranges of deletions (16 bp to 39 bp) which led to disruption of the exon-intron boundary, few base substitutions, and a 1 bp insertion at 3 bp upstream of the PAM region of the target site. The decrease in chlorophyll a/b, and carotenoid content in the mutant lines further confirmed the functional disruption of the HlPDS gene. Taken together, our results demonstrate that the CRISPR/Cas9 system can precisely edit the targeted genome sequences, which may revolutionize our way to overcome some of the obstacles that have plagued the traits improvement in hop.
Laryngeal dysplasia represents a series of precancerous lesions, observed as laryngeal leukoplakia. General agreement has been lacking for their management and treatment ranging from simple biopsy to complete excision with cold blade/laser. In this work, we aim at providing the oncological outcomes of patients affected by laryngeal dysplasia, treated with a single modality, and at identifying clinical parameters predictive of malignant transformation.

We performed a retrospective analysis of patients treated with transoral laser microsurgery between January 2005 and December 2015 in a tertiary comprehensive cancer centre. Data were collected about smoke and alcohol habits, site of the laryngeal lesion, surgical outcomes and progression to invasive squamous cell carcinoma.

The grade of dysplasia, margins' status and smoke habit were not associated with a significantly worse DFS and a higher risk of invasive SCC. We identified three parameters (supraglottic involvement, multifocality and history of more than one recurrence of dysplasia) that have a significant prognostic value.

On the base of these clinical parameters, a more intensive follow-up might be warranted for high-risk patients.

Idiopathic sudden sensorineural hearing loss (ISSHL) is an emergency otological disease, and its definite prognostic factors remain unclear. This study applied machine learning methods to develop a new ISSHL prognosis prediction model.

This retrospective study reviewed the medical data of 244 patients who underwent combined intratympanic and systemic steroid treatment for ISSHL at a tertiary referral center between January 2015 and October 2019. We used 35 variables to predict hearing recovery based on Siegel's criteria. In addition to performing an analysis based on the conventional logistic regression model, we developed prediction models with five machine learning methods least absolute shrinkage and selection operator, decision tree, random forest (RF), support vector machine, and boosting. To compare the predictive ability of each model, the accuracy, precision, recall, F-score, and the area under the receiver operator characteristic curves (ROC-AUC) were calculated.

Former otological history, ear fullness, delay between symptom onset and treatment, delay between symptom onset and intratympanic steroid injection (ITSI), and initial hearing thresholds of the affected and unaffected ears differed significantly between the recovery and non-recovery groups.
