This assignment paves the way for future studies of inter-domain interactions and dynamics that have to be taken into account when studying the regulation of Grb2 interactions and signaling pathways.Globally farmers have difficulty in extending the shelf-life of the tropical fruits due to their perishable nature. The present study aimed to assess the effect of hexanal nano-formulation treatment (NFT) on the shelf-life of Alphonso mango. Further, volatilomics was performed to explore the molecular basis of such effect. Untreated and treated fruits were sampled starting from 5th to 21st day after NFT at an interval of 4 days. Moderate changes in visual and digital colour parameters were evident from the intact and dissected fruits of NFT set compared to untreated fruits. Biochemical assays affirmed the phenotypic differences with significant changes in the colour imparting compounds like carotenoids and anthocyanins among them. Further, gas chromatography-mass spectrometry analysis revealed significant qualitative and quantitative variations in the different classes of compounds like lactones, furanones, esters, aldehydes and alcohols. Some of the key metabolites showed differential modulations among the NFT and untreated fruit sets indicating their potential role in various processes, which ultimately might have resulted in delayed ripening of the mango. Overall, this study has demonstrated the beneficial effect of hexanal and identified important metabolites with the enhanced shelf-life in Alphonso that could be useful for farmers and mango-based food/flavour industries.

The TWIST (Testicular Work-up for Ischemia and Suspected Torsion) score was developed to allow for expedited diagnosis of testicular torsion (TT) in children based on clinical variables edema (2 points), hard mass (2), absent cremasteric reflex (1), high-riding testis (1) and nausea/vomiting (1). We sought to validate the TWIST Score applied by non-expert physicians for the diagnosis of testicular torsion in an adult population.

We prospectively analyzed all consecutive males presenting to a tertiary hospital with acute scrotum. Patients with previous scrotal pathology or trauma were excluded. Physical examination was performed by a general surgeon and variables of TWIST were recorded. All patients underwent Scrotal Doppler Ultrasound. Measures of accuracy of the TWIST score and ROC curves were generated to evaluate its performance in diagnosing TT in adults.

Of 68 patients, 34 had TT (50%). Median age was 24.9years. According to the original cutoffs of TWIST, 23 patients had a score ≤ 2 among which none had TT. Fifteen patients had a score of 3-4, among which seven had TT. Thirty patients had a score ≥ 5, among which 27 had TT. All 18 patients with a score of 6 or greater had TT (100% PPV). ROC curve revealed an AUC of 0.95.

The TWIST Score is valid for the diagnosis of Testicular Torsion in adults, presenting a PPV of 90% for a cutoff of 5 points and 100% for six points. In all patients with a score of 2 or less, the disease could be safely excluded (100% NPV).

There is no consensus across guidelines on a diagnostic algorithm for upper urinary tract (UUT) evaluation following presentation with haematuria. Our aim is to compare the diagnostic accuracy of ultrasound (USS) compared to CT-scan for UUT malignancies and also determine the considerations important for a risk-based diagnostic protocol for haematuria.

We reviewed our 'haematuria clinic' database to identify patients who had both USS and CT-scan for UUT evaluation between September 2015 and August 2017, and calculated the diagnostic accuracy of these imaging modalities for histologically confirmed UUT cancers. Furthermore, we identified risk factors in our diagnostic algorithm for haematuria and conducted regression analysis to determine their ability to predict UUT malignancies.

Overall, 575 patient records were studied. Age range was 21-92years, MF was 1.41, majority (81.2%) had visible haematuria, and 12 (2.1%) UUT cancers were diagnosed [renal cell carcinoma-1.4%; upper tract urothelial cancer-0.7%]. USS and CT-scan had diagnostic accuracy for UUT cancers of 95.8 and 99.1%, respectively (p < 0.001). Haematuria type was a significant consideration only on univariate analysis, while multivariate binary logistic regression showed that male gender, smoking, occupational exposure, and positive urologic history were the main risk factors associated with UUT malignancies.

USS and CT-scan have comparably high diagnostic accuracy for detecting UUT malignancies. USS may, therefore, be considered as the first-line UUT imaging modality when utilized in a risk-based diagnostic algorithm. Larger, multicentred studies are needed to validate our findings and influence guideline development.

To describe our experience in handling cases of children with fibroepithelial polyps (FEPs) of ureters. We specifically present preoperative diagnosis approaches, provide a clear definition of this entity and its outcomes following treatment.

Clinical data of children with FEPs who were consecutively treated at Beijing Children's Hospital from January 2006 to May 2019 were retrospectively analyzed in this study. The clinical data reviewed included diagnostic, intraoperative, and follow-up data.

Of the 2653 children with surgery for hydronephrosis reviewed, 48 (1.8%) cases of FEPs of the ureters were identified, with a mean age of 109 ± 34.7months. Among them, males accounted for 95.8%, left side for 81.3%, and proximal ureteral polyps for 97.9%. Notably, 70.8% of patients had only 1 polyp and the median size of the polyps was 2.1 ± 1.8cm. ECC5004 datasheet All patients underwent ultrasound before surgery, which revealed the existence of polyps in 29 (60.4%) children. These polyps were completely resected surgically. The mean follow-up was 82months (range of 6-153months) and no cases of recurrences of polyps were seen after surgery during follow-up.
