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).

A team of researchers at Cedars-Sinai Medical Center in Los Angeles and NeuroVision Imaging, a Sacramento, California firm, have developed a retinal imaging system that could allow early detection of Alzheimer’s disease. One of the hallmarks of Alzheimer’s disease is the accumulation of beta-amyloid protein in the brain. There are numerous ways to monitor levels of beta-amyloid in the nervous system, including cerebrospinal fluid analysis, or imaging techniques like positron emission tomography. However, these techniques are invasive and expensive, meaning that they are unsuitable for routine screening to ...

BIOTRONIK has obtained an FDA approval for its Edora HF-T QP MR conditional quadripolar cardiac resynchronization therapy pacemaker (CRT-P). It’s tiny, by comparison to similar devices, and features the BIOTRONIK’s MR AutoDetect technology that allows a physician to tell the implant that an MRI exam is coming up and for the device to automatically engage its MRI safety mode during a scan. The implant has a total volume of only 15 cc, making it the smallest MR-conditional CRT-P on the U.S. market. Being a modern pacemaker, it includes wireless monitoring for daily uploads of any unusual events to the patien...

We report a case of a 21-year-old, human immunodeficiency virus –positive, deceased-donor kidney recipient who presented 1 year after transplant with oliguric kidney injury. A nuclear medicine renal scan revealed absence of flow to the transplanted kidney, and a urine fungal culture was positive for Aspergillus flavus. The diagnosis was confirmed with the pres ence of fungal hyphae along with thrombosis in the vascular structures in renal allograft pathology.

ABSTRACT Lettuce (Lactuca sativa) is one of the most popular leafy vegetables in the world and constitutes a major dietary source of phenolic compounds with health promoting properties. In particular, the demand for green and red oak‐leaf lettuces have considerably increased in the last years but few data on their polyphenol composition is available. Moreover, the utilization of analytical edge technology can provide new structural information and allow the identification of unknown polyphenols. In the present study the phenolic profiles of green and red oak‐leaf lettuce cultivars were exhaustively characterized by ult...

Abstract The use of enzymes in organic solvents has considerably widened their repertoire of applications. Such low water containing media also offer the possibility of carrying out enzymatic reactions at higher temperatures and enhancing reaction yields. The utility of such preparations is limited by the damage caused to the protein structure during freeze-drying. This work investigates the result of exposing the proteolytic enzyme subtilisin to high temperature in low water containing n-octane on its activity in aqueous and non-aqueous media. Exposing subtilisin at 90 °C for 5 h led to 18-fold impr...

Abstract Sample preparation for scanning electron microscope analysis involves reagents and equipment that are expensive and often hazardous. Here we demonstrate a circumvention of Osmium tetroxide and critical point drying, greatly reducing the duration, complexity and cost of the process. We captured early stage interactions of invasive-bacteria and HeLa cells during the process of bacteria-mediated gene delivery and illustrate sufficient clarity can be obtained using this procedure to preserve and clearly visualize relevant cellular structures. This protocol is significantly cheaper and easier to adapt compared...

ConclusionLacosamide is an AED to consider in cases of cancer‐related seizures. Lacosamide pharmacodynamics and pharmacokinetics allow the achievement of responder rates over 50% with no serious adverse effects, amelioration of side effects from other AEDs or radio‐/chemotherapy, and no significant drug interactions. Furthermore, the intravenous formulation shows clear benefits in acute conditions such as status epilepticus.

Authors: Belkić K, Belkić D Abstract BACKGROUND: Ovarian cancer is a major cause of cancer death among women worldwide, and particularly in Israel. Although the disease at stage IA has 5 year survival rates of over 90%, early detection methods are not sufficiently accurate. Consequently, ovarian cancer is typically diagnosed late, which results in high fatality rates. An excellent candidate for early ovarian cancer detection would be in vivo magnetic resonance spectroscopy (MRS) because it is non-invasive and free of ionizing radiation. In addition, it potentially identifies metabolic features of cancer. Detectin...
