Two-photon fluorescent Acenaphtho[1,2-b]quinoxaline (ANQ) and the hydrophilic di-(triazole-[12]aneN3) moieties were combined through an alkyl chain (ANQ-A-M) or a β-hairpin motif with two aromatic γ-amino acid residues (ANQ-H-M) to explore their capabilities for in vitro and in vivo gene delivery and tracing. ANQ-A-M and ANQ-H-M showed the same maximum absorption at 420 nm, and their fluorescent intensities around 650 nm were varied in different solvents and became poor in the protic solvents. Gel electrophoresis assays indicated that both compounds completely retarded the migration of pDNA at 20 μM in the presence of DOPE. However, the DNA condensation with ANQ-H-M was not reversible, and the particle size of the corresponding complexes were larger indicated from the SEM and DLS measurements. In vitro transfections indicated ANQ-A-M/DOPE achieved Luciferase and GFP expressions were to be 7.9- and 5.7-fold of those by Lipo2000 in A549 cells respectively. However, ANQ-H-M showed very poor transfection efficien.

To investigate the detectability of pancreatic cystic lesions and main pancreatic duct dilation by low-dose unenhanced computed tomography (CT).

This study included 2684 patients who underwent low-dose unenhanced CT using iterative reconstruction and magnetic resonance imaging (MRI) as a part of a health-screening program between February 1, 2019 and December 31, 2019. Patients diagnosed with pancreatic cystic lesions and/or dilatations of the main pancreatic duct on MRI were identified. Detection rates by low dose CT in terms of lesion size were tested for significance by Fisher's exact test.

Of the 2684 patients, 558 (20.8 %) had pancreatic cystic lesions and 22 (0.8 %) had main pancreatic duct dilatation on MRI. The low-dose CT detection rates among the pancreatic cystic lesions were as follows 1-9-mm cysts, three (0.65 %) of 461; 10-19-mm cysts, 17 (21.25 %) of 80, and ≥20-mm cysts, eight (47.06 %) of 17. The detection rates were significantly higher in the 10-19-mm and the ≥20-mm cyst group than in the 1-9-mm cyst group (p <  0.001). The detection rates among the main pancreatic duct dilatations were as follows 3-5-mm dilatations, two (11.76 %) of 17 and ≥6-mm dilatations, four (80 %) of five, which were significantly higher rates than that for the 3-5-mm dilatations (p =  0.009).

Small pancreatic cysts and slight main pancreatic duct dilatation were practically undetectable by low-dose unenhanced CT. The application of a low-dose CT protocol as a screening tool in the detection of pancreatic abnormalities is not recommended.

To develop a nomogram incorporating B-mode ultrasound (BMUS) and shear-wave elastography (SWE) radiomics to predict malignant status of breast lesions seen on US non-invasively.

Data on 278 consecutive patients from Hospital #1 (training cohort) and 123 cases from Hospital #2 (external validation cohort) referred for breast US with subsequent histopathologic analysis between May 2017 and October 2019 were retrospectively collected. Using their BMUS and SWE images, we built a radiomics nomogram to improve radiology workflow for management of breast lesions. The performance of the algorithm was compared with a consensus of three ACR BI-RADS committee experts and four individual radiologists, all of whom interpreted breast US images in clinical practice.

Twelve features from BMUS and three from SWE were selected finally to construct the respective radiomic signature. The nomogram based on the dual-modal US radiomics achieved good diagnostic performance in the training (AUC 0.96; 95% confidence intervals [CI], 0.94-0.98) and the validation set (AUC 0.92; 95% CI, 0.87-0.97). For the 123 test lesions, the algorithm achieved 105 of 123 (85%) accuracy, comparable to the expert consensus (104 of 123 [85%], P =  0.86) and four individual radiologists (93, 99, 95 and 97 of 123, with P value of 0.05, 0.31, 0.10 and 0.18 respectively). Furthermore, the model also performed well in the BI-RADS 4 and 5 categories.

Performance of a dual-model US radiomics nomogram based on SWE for breast lesion classification may comparable to that of expert radiologists who used ACR BI-RADS guideline.

This study aimed to assess the use of hepatocyte fraction in gadoxetic acid-enhanced magnetic resonance imaging (MRI) for quantitatively evaluating the liver function in comparison with T1 relaxation-based indices.

This retrospective study included 79 patients with chronic liver disease, who were divided into 2 groups based on the results of the indocyanine green retention test (ICG). All patients underwent a gadoxetic acid-enhanced MRI of the liver. Pre- and post-contrast Look-Locker sequences were used 20 min after gadoxetic acid administration to acquire T1 mapping. Two readers independently identified and measured the MRI parameters [five T1 relaxation-based indices (T1pre, T1post, rrT1, R1post/R1pre and ΔR1) and two hepatocyte fraction indices (HeF and K

)]. An Independent-samples t test was used to compare each parameter for the two groups. Pearson correlation analysis was used to analyze the correction in each parameter and 15-minute ICG retention rate (ICG-R15). Receiver operating characteristic -enhanced T1-mapping MRI is an efficient diagnostic tool for the quantitative evaluation of liver function.Mutations in the gene that encodes the nuclear envelope proteins lamin A/C (LMNA) are considered to be a prominent cause of Dilated cardiomyopathy (DCM), a leading cause of heart failure and a prevalent indication for heart transplant. Here we described the generation of induced pluripotent stem cells (iPSCs) from a 53-year-old female with DCM plus progressive conduction disease who carry a heterozygous mutation in LMNA (c.1621C > T, p.R541C). PBMCs isolated from the patient were reprogrammed with Yamanaka factors KOS, KLF4, and c-MYC by the non-integrating sendai virus vector system. The obtained iPSC lines demonstrated normal karyotype and pluripotent identity.Like the rest of Scandinavia, Denmark and Norway have a strong tradition of comprehensive topographical descriptions, often written by local clergymen. Physical-economic descriptions of small areas, most often parishes, emerging in the middle of the eighteenth century soon formed a model that remained strikingly uniform until around 1820, when the topographies changed once again. In the Dual Monarchy of Denmark and Norway, the years between 1760 and 1820 revealed a prolific topographic genre in which natural history and natural resources played important parts. Natural history was essential, being regarded as the condition for the composite peasant economy and offering the opportunity to reveal unknown sources of livelihood or intensify the use of those sources. Natural history was not only an aspect of the locality that should be dealt with in the description of the locality, but it became an entire scheme or method for the whole description, in which knowledge took up the form of inventories as did natural history itself. The topographical descriptions give hints as to the sort of observing, collecting, identifying, sorting, and ordering practices that lay behind the text. The concise and neutral form of these topographies did not give much room for the emotionality otherwise considered in the period as both a precondition for and an effect of dealings with natural history, and only rarely, in small gaps, did the sensual and aesthetic preferences of the authors come through, occasionally revealing their doubts but also their love of nature.

The purpose of this study is to evaluate chest CT imaging features, clinical characteristics, laboratory values of COVID-19 patients who underwent CTA for suspected pulmonary embolism. We also examined whether clinical, laboratory or radiological characteristics could be associated with a higher rate of PE.

This retrospective study included 84 consecutive patients with laboratory-confirmed SARS-CoV-2 who underwent CTA for suspected PE. The presence and localization of PE as well as the type and extent of pulmonary opacities on chest CT exams were examined and correlated with the information on comorbidities and laboratory values for all patients.

Of the 84 patients, pulmonary embolism was discovered in 24 patients. We observed that 87% of PE was found to be in lung parenchyma affected by COVID-19 pneumonia. Compared with no-PE patients, PE patients showed an overall greater lung involvement by consolidation (p=0.02) and GGO (p<0.01) and a higher level of D-Dimer (p<0,01). Moreover, the PE group showed a lower level of saturation (p=0,01) and required more hospitalization (p<0,01).

Our study showed a high incidence of PE in COVID-19 pneumonia. In 87% of patients, PE was found in lung parenchyma affected by COVID-19 pneumonia with a worse CT severity score and a greater number of lung lobar involvement compared with non-PE patients. CT severity, lower level of saturation, and a rise in D-dimer levels could be an indication for a CTPA.

Certain findings of non-contrast chest CT could be an indication for a CTPA.

Schisandra chinensis fruit extract was used as a model plant extract. Hybrid grape-like mineral was assembled by calcium carbonate mineralization. The hybrid particles of S. chinensis mineral were fully characterized using field emission scanning electron microscopy, X-ray diffraction, thermogravimetric analysis, and particle size analysis. Data including the Brunauer-Emmett-Teller surface area, single point total pore volume, and adsorption/desorption analysis of pore size were also investigated. Organic molecules, including lipids such as palmitic acid, stearic acid, and linolenic acid in the Schisandra chinensis fruit, affect the formation of complex structures involving the CaCO3 mineralization pathway by inhibiting crystallization. However, the cosmetic active primary components were entrapped in a similar proportion in the preserved extract, and were efficiently separated without additional filtering and concentration steps for purification. read more In addition, the hybrid mineral was enriched (10.5 times) in Gomisin N, a representative component of S. chinensis fruit, relative to its concentration in the initial extract samples. The hybrid mineral inhibited both intracellular and extracellular melanin production and increased the 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity. The data provide the first evidence of the potential use of fruit extract for obtaining hybrid minerals and the effectiveness of the biomineralization-based separation and concentration strategy.
