Comparison of dimensional accuracy of conventionally and digitally manufactured intracoronal restorations

ConclusionsWithin the limitations of this in vitro study, the conventional method yielded more accuracy than the 3D printing method, and no differences were found between the methods which used the 3D printer (groups CP and IP).

Thymic carcinomas are rare malignant tumors, located in the anterior mediastinum. For the treatment of these carcinomas, several chemotherapy regimens have been suggested, including carboplatin plus paclitaxel. However, because of the rarity of these tumors, the standard chemotherapy regimen has not yet been established. Here, we report a case of thymic carcinoma that responded to first-line carboplatin plus nanoparticle albumin-bound paclitaxel (nab-paclitaxel) therapy with continuation maintenancenab-paclitaxel monotherapy. A 78-year-old male presented to a hospital with the chief complaint of dyspnea. Cardiomegaly was d...

We report a rare case of spontaneous rupture of liver hematoma in patient treated with warfarin end enoxaparin sodium because of pulmonary embolism. Two day after admission the patient complained generalized abdominal pain and hemodynamic instability. The abdominal US and TC scan revealed free fluid and lesion at right liver lobe. The patient, despite intravenous fluid support and blood transfusion, was hemodinamically instable and urgent laparotomy was needed. At laparotomy, it was found that a subcapsular haematoma, involving the diaphragmatic face of the right liver, had ruptured into peritoneum. Hepatic bleeding was st...

Authors: Capizzi A, Sacco O, Rossi GA, Silvestri M Abstract Recurrent pneumonia is one of the most frequent reasons for referral to paediatric chest physicians. The diagnostic work-up is dependent on whether infection repeatedly occurs in the same lung lobe, or affects multiple lobes and/or different areas in different episodes. A 13-year-old girl was admitted with a second episode of right lower lobe pneumonia. The chest x-ray demonstrated an inhomogeneous opacity, without a clearly recognizable segmental distribution. A contrast-enhanced CT scan, was therefore performed that showed a polycyclic consolidation with...

Authors: Kebbe J, Yendamuri S, Roche C, Harris K, Dhillon SS Abstract A 43-year old man presented with recurrent pneumonias, episodes of hemoptysis and an enlarging right lower lobe mass. A clear diagnosis was not previously established in spite of multiple radiological evaluations and biopsies. Meticulous review of his CT imaging showed that he had subcarinal calcification on his prior CT scans, which had decreased in size and now multiple new small areas of calcifications were seen in the right lower lobe lesion. An esophago-pulmonary fistula due to migration of mediastinal calcifications was suspected which was ...

Publication date: Available online 23 June 2017 Source:Methods Author(s): Jörg Langowski Single plane illumination microscopy (SPIM) is a new optical method that has become extremely important in recent years. It is based on the formation of a “light slice“ in the specimen in which fluorescently tagged molecules are observed. The spatial resolution is close to that of confocal optics, but without the disadvantages inherent to scanning or high laser irradiation doses. A recent development is light sheet fluctuation microscopy, which exploits the dynamic information contained in the fluorescence intensity f...

Publication date: 10 September 2017 Source:Thermochimica Acta, Volume 655 Author(s): Yash Pal, V. Ravi Kumar Hybrid rocket fuels are considered safer compared to solid and liquid based rocket fuels due to operational and handling reasons. The thermal stability and combustion capability are important aspects determining the usability and their efficiency. In this work, thermal decomposition studies were carried out on Paraffin blended Polyethylene (P/PE)-based solid hybrid fuels incorporated with metallic additives under N2 and O2 environment using Differential Scanning Calorimeter (DSC). The metallic additives such as Alu...

Langdon Low-carbon steel AISI 1020 was subjected to high-pressure torsion (HPT) with 6.0GPa pressure through 1/4–5 turns. The microstructures of the samples in each turn were studied by means of X-ray diffraction (XRD) analyzing the changes in micro-strain, crystallite size and lattice parameter. Vickers testing was utilized to study the microhardness behavior of the samples subjected to HPT processing. The morphology evol...

Conclusions In African Americans with T2DM, mildly high UACR and mildly low eGFR were associated with smaller GMV and increased white matter lesion volume. UACR was associated with poorer processing speed and working memory.

This study was designed to evaluate the utility of textural features for predicting pathological complete response (pCR) to neoadjuvant chemotherapy (NAC).MethodsSixty-one consecutive patients with locally advanced breast cancer underwent18F-FDG PET/CT scanning at baseline and after the second course of NAC. Changes to imaging parameters [maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), total lesion glycolysis (TLG)] and textural features (entropy, coarseness, skewness) between the 2 scans were measured by two independent radiologists. Pathological responses were reviewed by one pathologist, and th...
