Four-dimensional digital tomosynthesis image reconstruction using brute force-based adaptive total variation (BF-ATV) in a prototype LINAC system.

In conclusion, the proposed low-dose 4D-DTS reconstruction scheme may provide better performance due in part to its rapid scanning. Therefore, it is potentially applicable to practical 4D imaging for radiotherapy. PMID: 30840940 [PubMed - as supplied by publisher]

;š M Abstract Superior Shoulder Suspensory Complex (SSSC) is a bone and soft-tissue ring securing the connection of the upper extremity to the axial skeleton via the clavicle and sternoclavicular joint. An isolated injury to one component of SSSC is usually stable. An injury to 2 of its components is a potential source of shoulder girdle instability and requires surgical stabilisation. An injury affecting 3 and more components is extremely rare and surgical stabilisation should be indicated. Our study presents the case of a 50-year-old man who fell off the bicycle and sustained a direct blow to his left sho...

Publication date: March 2020Source: Food Hydrocolloids, Volume 100Author(s): Yang Li, Mingda Li, Yuman Qi, Li Zheng, Changling Wu, Zhongjiang Wang, Fei TengAbstractFish oil is used for its numerous health and nutritional benefits. Nevertheless, it is unstable during production, storage, and application. Nanoemulsions can be used as an effective carrier for encapsulated nutraceuticals. The effects of different components on the stability of fish oil nanoemulsions with soybean protein isolate-phosphatidylcholine (SPI-PC) were studied by characterizing particle size, polydispersity index, ζ-potential, turbidity, and turb...

Kamble, Ashutosh Upadhyay, Barjinder Pal KaurAbstractPhysicochemical and functional properties of refined wheat flour (RWF), soy flour (SF), sorghum flour (SGF) as well as multigrain flour (MF) prepared with a blend of RWF (62.2%), SGF (24.6%) and SF (13.2%), were evaluated in relation to their noodles making potential. Results showed that MF did not differ significantly from RWF for its bulk density, swelling, water absorption and oil absorption capacity. However, the solubility score improved signific...

In this report, we have prepared Cu-doped ZnO nanorods by a simplistic wet chemical method with subsequent annealing. The phase formation, optical, surface morphological studies along with the electrical properties of the Cu doped ZnO thin films were characterized by X-ray diffraction (XRD), photoluminescence (PL), field emission scanning electron microscopy (FESEM) and Hall measurements, respectively. The addition of copper (Cu) in to the matrix of ZnO influenced the surface morphology of the product dramatically. The regular hexagonal nanorods-like surface morphology of ZnO becomes a broken rod-like morphology, after add...

It is bioconverted by Mycobacterium sp. LY-1 from phytosterols. During biotransformation, the low solubility of phytosterols in water limits 9α-OH-AD production. In the present work, polyoxyethylene (10) nonylphenyl ether (TX-40), a nonionic surfactant, was first used to enhance phytosterol sol...

In this study, we reported an electrochemical synthesis of graphene (Gr) functionalized with silver nanorods (Ag NRs) using 3D surfactant 4-sulphocalix [4] arene (SCX) and silver nitrate (AgNO3) from an aqueous solution. SCX is acted as a soft template to form Ag NRs along with the Gr sheets. UV-Vis (UV-Vis), Fourier-transform infrared (FT-IR) and Raman spectroscopies have confirmed the formation of Gr with Ag NRs. In order to develop a selective electrochemical sensor for OA, Gr-Ag NRs nanocomposite coated glassy carbon electrode (GCE) was prepared and tested for OA oxidation. This new sensor (Gr-Ag NRs/GCE) exhibited hig...
