Camellia oil authentication: A comparative analysis and recent analytical techniques developed for its assessment. A review

Publication date: Available online 9 January 2020Source: Trends in Food Science &TechnologyAuthor(s): Ting Shi, Gangcheng Wu, Qingzhe Jin, Xingguo WangAbstractBackgroundCamellia oil is obtained from the camellia seed with various cultivated species (Camellia. oleifera (C. oleifera), C. meiocarpa, C. vietnamensis, C. yuhsienensis, C. chekiangoleosa, C. semiserrata, C. reticulata, C. gigantocarpa, C. octopetala, C. semiserrata var. abliflora etc.), by widely used cold press extraction. As the earliest specie with high oil yield (40–60%) in China, C. oleifera, has become the most commonly available seed for camellia oil manufacturing. Because of its high nutritional and economic value, camellia oil is frequently adulterated with other cheap oils. Additionally, its quality is also susceptible to different species or regions, and various extraction technologies. These factors result in the incorrect labeling of camellia oil, and destabilize the local camellia oil market economies. Therefore, a rapid and accurate method should be prerequisite to authenticate camellia oil.Scope and approachThe officially recommended methods are tedious, and destructive to detect camellia oil adulteration. Therefore, various rapid, precise, and non-destructive techniques should be developed for camellia oil authentication. This present review provides a critical overview of these existing analytical methods in the past few years.Key findings and conclusionThe mass-chromatographic, spectrosc...

To improve HF treatment, a comprehensive HF management program (4D project) was implemented in the Stockholm County (>2.1 million inhabitants). Design. A standardized care program centralized at five hospital-based HF clinics was implemented in 2014-2017. We registered from 2012 to 2017: (1) numbers of referrals and v...

In this study, a state-of-the-art custom U-Net model is presented with a dice similarity coefficient performance of 99.6% along with a transfer learning VGG-19 based model for COVID-19 versus pneumonia differentiation exhibiting an area under curve of 96.1%. The above was significantly improved over the baseline model trained with no segmentation in selected tomographic slices of the same dataset. The presented study highlights the importance of a robust preprocessing protocol for image analysis within a heterogeneous imaging dataset and assesses the potential diagnostic value of the presented COVID-19 model by comparing i...

 ATLANTA —Scientific literature has shown intraoral scanners to be highly successful in creating digital impressions for designing short-span restorations and partial prosthesis; however, scanning fully edentulous arches is less studied. Now, a new comprehensive in-vitro study testing the trueness of 12 intraoral scanners when scanning full-arch implant impressions has found the CS 3700 intraoral scanner to offer the truest results when capturing scan bodies in an edentulous arch, giving doctors more confidence that they ’re getting the best results when creating digital impressions with the CS 3700. ...

Authors: Li L, Sun W, Han M, Ying Y, Wang Q Abstract BACKGROUND Early and rapid identification of severe coronavirus disease 2019 (COVID-19) cases is important. The present study aimed to investigate the predictors of disease severity and thus determine the trends for disease progression early. MATERIAL AND METHODS Patients with COVID-19 were recruited from Fuyang Second People's Hospital from January to February 2020. Patients' demographic, epidemiological, and clinical data were collected, and the relationships between these variables and disease severity were analyzed. RESULTS A total of 158 cases were included ...

This article describes a patient who presented to the ED with abdominal pain, nausea, and vomiting. A CT scan revealed dilated loops of bowel with an adjacent air-filled structure, possibly related to an internal hernia. Meckel diverticulum was discovered on diagnostic laparoscopy and a mesodiverticular band was lysed; the diverticulum was left in situ. The patient did well without further invention needed.
