Determining Engineering pertaining to COVID-19: Which are the Issues with regard to Wellbeing Technology Assessment Businesses? Results From the Review and Roundtable Class.
Previous studies demonstrated the benefits of motor exercise and physical activity in neuromuscular disorders. However, very few papers assessed the effects of sport practise. The aim of this multicentre study was to assess the impact of sport activity on self-esteem and emotional regulation in a cohort of athletes with neuromuscular disorders. The 38 patients with Duchenne, Becker or other types of muscular dystrophy or spinal muscular atrophy practising sport (aged 13-49 years) and 39 age-, gender-, disability- and disease-matched patients not practising sport were enrolled. Testing procedures to assess self-esteem, anxiety and depression disorder, personality trait and quality of life (QoL) were used. Patients practising sport had a significantly higher self-esteem, lower level of depression, greater social own identity and adherence and QoL. Frequency of sport activity may represent a complementary therapy in neuromuscular disorders to improve mental and social well-being.The functional analysis of human papillomavirus (HPV) sequence variation requires the molecular cloning of different genomic regions of virus variants. In this study, we report an unexpected difficulty experienced when trying to clone HPV33 long control region (LCR) variants in Escherichia coli. Standard cloning strategies proved to be inappropriate to clone HPV33 LCR variants in the forward orientation into a eukaryotic reporter vector (pGL2-Basic). However, by slight modification of culture conditions (incubation at 25 °C instead of 37 °C), constructs containing the HPV33 LCR variants in the forward orientation were obtained. Transformation experiments performed with different HPV33 LCR constructs indicated that there is a sequence element in the 5' LCR of HPV33 causing temperature-dependent toxic effect in E. coli. Sequence analysis revealed the presence of an open reading frame (ORF) in the 5' part of HPV33 LCR potentially encoding a 116-amino acid polypeptide. Protein structure prediction suggested that this putative protein might have a structural similarity to transmembrane proteins. Even a low-level expression of this protein may cause significant toxicity in the host bacteria. In silico analysis of the LCR of HPV33 and some other HPV types belonging to the species Alphapapillomavirus 9 (HPV31, 35 and 58) seemed to support the assumption that the ORFs found in the 5' LCR of these HPVs are protein-coding sequences. Further studies should be performed to prove that these putative proteins are really expressed in the infected host cells and to identify their function.PURPOSE We aimed to compare the computed tomography (CT) imaging differences between gastric and intestinal gastrointestinal stromal tumors (GISTs). MATERIALS AND METHODS Thirty-eight patients with 38 gastric GISTs and 27 with 31 intestinal GISTs were enrolled. Tumors were classified as small ( less then  5 cm) or large (≥ 5 cm). Qualitative and quantitative CT imaging characteristics on non-contrast and contrast-enhanced CT were evaluated by two radiologists independently and statistically compared. RESULTS Early venous return and higher CT number of the draining vein in the arterial phase were more frequent in small-sized intestinal GISTs than in small-sized gastric GISTs (p  less then  0.001). Small-sized intestinal GISTs demonstrated a wash-out pattern, whereas small-sized gastric GISTs showed a plateau pattern. Contrast enhancement was higher in small-sized intestinal GISTs than in small-sized gastric GISTs (p  less then  0.001). CT number was inversely proportional to the diameter of intestinal GISTs in both arterial and venous phases but not to that of gastric GISTs. CONCLUSION Strong enhancement with wash-out pattern and early venous return are characteristic findings of small-sized intestinal GISTs. Radiologists should be aware that CT findings of GISTs have a wide spectrum and may differ according to size and site of origin.PURPOSE To assess MR imaging findings of low-grade serous carcinoma (LGSC) of the ovary compared with those of serous borderline tumor (SBT). METHODS Twenty-four patients with histopathologically proven 7 LGSCs and 25 SBTs who underwent preoperative MR imaging were included. We retrospectively reviewed MR images and compared MR findings between the two pathologies. RESULTS The predominantly solid lesions were marginally more frequent in LGSCs than in SBTs (43% vs. Ispinesib 8%, p = 0.057). All predominantly cystic LGSCs were multilocular cystic lesions with mural nodules. Predominantly solid LGSCs exhibited pure solid masses in 2 of 3 and solid masses with intratumoral cysts in 1 of 3. Papillary growth pattern with internal branching was observed only in 18 of 25 SBTs. Signal intensity ratio on T2-weighted images (4.48 ± 1.55 vs. 8.40 ± 3.53, p  less then  0.01) and apparent diffusion coefficient (ADC) values (1.12 ± 0.21 vs. 1.73 ± 0.27 × 10-3 mm2/s, p  less then  0.01) of solid components was significantly lower in LGSCs than in SBTs. CONCLUSION Compared with SBTs, lower signal intensity on T2-weighted images and lower ADC values were characteristic features of solid components in LGSCs. Papillary growth pattern with internal branching was not observed in LGSCs.The usefulness of whole-body 18-fluoro-2-deoxyglucose (FDG)-fluorodeoxyglucose positron emission (PET)/computed tomography (CT) is established for assessment of disease staging, detection of early disease recurrence, therapeutic evaluation, and predicting prognosis in various malignancies; and for evaluating the spread of inflammation. However, the role of FDG-PET/CT for the liver is limited because CT and magnetic resonance imaging (MRI) can provide an accurate diagnosis of most tumors. In addition, in other potentially useful roles there are several pitfalls in the interpretation of FDG uptake in PET/CT imaging. Accurate evaluation demands knowledge of the FDG uptake of each lesion, including potential negative and positive uptakes, and requires an understanding of the underlying background of the molecular mechanisms. The degree of FDG uptake is dependent on cellular metabolic rate and the expression of glucose transporter, hexokinase, and glucose-6-phosphatase, which in turn are closely affected by biological characteristics such as pathological category (e.g., adenocarcinoma, squamous cell carcinoma, small cell cancer, transitional cell cancer, neuroendocrine tumor, sarcoma, lymphoma), tumor differentiation, histological behavior (e.g., solid, cystic, mucinous), and intratumoral alterations (e.g., necrosis, degeneration, hemorrhage). Correlation with the CT and MRI findings, which also precisely depict the pathological findings, is important to avoid misdiagnosis.Genome-wide identification, spatio-temporal expression analysis and functional characterization of selected Brassica napus GPATs highlight their roles in cuticular wax biosynthesis and defense against fungal pathogens. Glycerol-3-phosphate 1-O-acyltransferase (GPAT) is a key enzyme in the biosynthesis of glycerolipids, a major component of cellular membranes and extracellular protective layers, such as cuticles in plants. Brassica napus is an economically important crop and cultivated worldwide mostly for its edible oil. The B. napus GPATs (BnGPATs) are insufficiently characterized. Here, we performed genome-wide analysis to identify putative GPATs in B. napus and its diploid progenitors B. rapa and B oleracea. The 32 B. napus BnGPATs are phylogenetically divided into three major groups, cutin, suberin, and diverse ancient groups. Analysis of transcriptomes of different tissues and seeds at different developmental stages revealed the spatial and temporal expression profiles of BnGPATs. The yield and oil quality of B. napus are adversely affected by the necrotrophic fungus, Sclerotinia sclerotiorum. We showed that several BnGPATs, including cutin-related BnGPAT19 and 21, were upregulated in the S. sclerotiorum resistant line. RNAi-mediated suppression of BnGPAT19 and 21 in B. napus resulted in thinner cuticle, leading to rapid water and chlorophyll loss in toluidine blue staining and leaf bleaching assays. In addition, the RNAi plants also developed severe necrotic lesions following fungal inoculation compared to the wild-type plants, indicating that BnGPAT19 and 21 are likely involved in cuticular wax biosynthesis that is critical for initial pathogen defense. Taken together, we provided a comprehensive account of GPATs B. napus and characterized BnGPAT19 and 21 for their potential roles in cuticular wax biosynthesis and defense against fungal pathogens.OBJECTIVES Ubiquitination has a role as a host defense mechanism against pathogens. To channelize autophagic mycobacteria to destruction, ubiquitin ligase like, Makorin Ring Finger Protein 1 (MKRN1) was speculated to play a role in ubiquitinating M. tuberculosis. We have developed a flow cytometry based in vitro ubiquitin ligase assay to understand the role of MKRN1 in ubiquitinating mycobacteria and confirmed the results by western blotting. RESULTS MKRN1 was cloned and expressed in E. coli BL21 (DE3) strain. The recombinant MKRN1 protein was solubilised, purified and refolded to restore the activity. In addition, through autoubiquitination assay, the activity of protein was confirmed. The corresponding E1 and E2 enzymes for MKRN1, UBE1 and UBE2D3 respectively, were selected using BioGrid tool. Surprisingly, flow cytometric assay revealed that at a concentration of 300 nM of MKRN1, 38% of M. tuberculosis was found to be ubiquitinated in vitro with 3.5% of the cells having bound MKRN1. Immunoblot results also substantiates the ubiquitination of M. tuberculosis. MKRN1 did not ubiquitinate B. Subtilis and therefore, we speculate that the E3 Ub ligase activity might be specific to M. tuberculosis. CONCLUSION This clearly demonstrates that recombinant MKRN1 ubiquitinates M. tuberculosis which opens up a novel, potential role of MKRN1 against mycobacteria which has to be unfolded.OBJECTIVE Although the extracellular polysaccharides have been analyzed in the previous period, the biochemical, enzymological characters and stimulation and inhibition effect on glucansucrase are not fully understood. RESULTS After three steps purification, salting out, DEAE-Sepharose and Sephadex G-75, the final specific activity was 264.84 U/mg protein with 4.31-fold. The SDS-PAGE analysis of fraction gave a single band 170.35 kDa in the stained gel. The active band was analyzed with LC-MS/MS to identify glucansucrase. The highest coverage rate of dextransucrase from Leu. citreum (ACY92456.2) was 55.60%, the results were speculated that the glucansucrase secreted from Leu. citreum B-2 may be a novel glucansucrase. The purified enzyme was optimally active at 20-30 °C and pH 6.0-8.0. Metal ions K+, Na+, Ca2+, Mn2+, Mg2+, and Cr+ had an apparent stimulating effect on enzyme activity, especially in divalent ions Ca2+ and Mn2+, the residual activities were higher than 200%. In a reverse, Hg+, acetonitrile, SDS, salt, and guanidine expressed inhibition effect on enzyme residual activity. The KM and Vmax were detected to be 4.82 mM and 0.97 U/mg, respectively. CONCLUSION All these data collectively indicate that B-2 glucansucrase is a novel one, which have good properties and may applied to new food areas.
