A simplified method for the determination of alpha-tocopherol concentration in beef muscle was developed and evaluated. The method consists of a saponification step applied to 1-g samples of intact, fresh muscle, followed by a single isooctane extraction of the saponified samples. alpha-Tocopherol in the extract was separated by normal phase chromatography and quantified by fluorescence detecti...

BACKGROUND In head and neck cancer patients undergoing radiotherapy, osteoradionecrosis (ORN) of the jaw is one of the major but uncommon complications. Satisfactorily results have been observed while treating ORN patients with upcoming treatment modalities such as combination therapy of pentoxifylline and Vitamin E (PVe). It is believed that in patients undergoing dental extractions, these tre...

BACKGROUND Extraction of teeth is the commonest surgical procedure carried out in the dental surgery setting. AIM The purpose of this survey was to identify the causes of teeth extraction in Eastern Nigeria. SUBJECTS AND METHODS Record forms for entering data and a self-addressed return envelope were distributed to 100 dental surgeons in Eastern Nigeria using a simple random selection. RE...

Regular expressions with capture variables, also knownas “regex formulas,” extract relations of spans (inter-val positions) from text. These relations can be fur-ther manipulated via Relational Algebra as studied inthe context of document spanners, Fagin et al.’s for-mal framework for information extraction. We investigate the complexity of querying text by ConjunctiveQu...

In case of fire in a building, how will people behave in the crowd? The behavior of each individual affects the behavior of others and, conversely, each one behaves considering the crowd as a whole and the individual others. In this article, I propose a three-step method to explore a brand new way to study behavior dynamics. The first step relies on the creation of specific situations with stan...

The following application note demonstrates the ability of Immobilized Liquid Extraction Well Plates to provide high-throughput bioanalytical extractions of methadone and imipramine directly from serum. ILE Well Plates exhibit highly efficient (99.6%) and reproducible (± 0.6 – 4.1% RSD) extractions for a wide range of analyte concentrations (10 – 20,000 ng/mL).

Based on state of the art machine learning techniques, GROBID (GeneRation Of BIbliographic Data) performs reliable bibliographic data extractions from scholar articles combined with multi-level term extractions. These two types of extraction present synergies and correspond to complementary descriptions of an article. This tool is viewed as a component for enhancing the existing and the future ...

BACKGROUND Studies that show frequencies of different orthodontic treatment protocols can be used as valuable parameters in the interpretation of treatment tendency with time. The purpose of this retrospective study was to evaluate all orthodontic treatment planning conducted at the Orthodontic Department at Bauru Dental School, University of São Paulo, Brazil, since 1973, in order to investiga...
