Effectiveness of different cleanup sorbents for the determination of avermectins in fish by liquid chromatography tandem mass spectrometry.

An effectiveness and comparative study of cleanup sorbents used in dispersive solid phase extraction (DSPE) for the determination of avermectins, including emamectin (EMA), abamectin (ABA), doramectin (DOR), moxidectin (MOX), and ivermectin (IVE), was performed. Three different types of cleanup sorbents, alumina (Al), primary and secondary amine (PSA) and octadecyl (C18), were used to remove the matrix interference in fish samples. Homogenised fish samples were extracted with acetonitrile, magnesium sulphate anhydrous and sodium chloride. The cleanup sorbents were separately applied to the supernatant during the DSPE procedure; the mixtures were shaken and centrifuged, and the supernatant was dried. The extracts were reconstituted with acetonitrile/water and quantified by liquid chromatography tandem mass spectrometry with electrospray ionisation in the positive mode with two product ions that were monitored by selected reaction monitoring. The performance of each cleanup sorbent was observed for its accuracy and precision in a spiked blank sample at a concentration of 5 μg kg−1. The combination of the cleanup sorbents PSA and C18 was found to be the most effective in the cleanup of the fish samples. In the validation tests, the detection limit was in the range of 0.3 μg kg−1 to 0.4 μg kg−1, and the quantitation limit for all avermectins was 1 μg kg−1 in the linearity range of 1–15 μg kg−1. The recoveries of avermectins were 91.9–102.5%, with a relative standard deviation lower than 19%

Polygonumins A, a newly isolated compound from the stem of Polygonum minus Huds with potential medicinal activities

Polygonumins A, a new compound, was isolated from the stem of Polygonum minus. Based on NMR results, the compound’s structure is identical to that of vanicoside A, comprising four phenylpropanoid ester units and a sucrose unit. The structure diferences were located at C-3″″′. The cytotoxic activity of polygonumins A was evaluated on several cancer cell lines by a cell viability assay using tetrazolium dye 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT). The compound showed the highest antiproliferative (p<0.05) activities against K562 (Human Leukaemia Cell Line), MCF7 (Human breast adenocarcinoma cell line), and HCT116 (Colorectal cancer cells) cells. Cytotoxic studies against V79–4 cells were carried out and showed that polygonumins A was toxic at 50µg/ml, suggesting that this compound may be used as an anticancer drug without afecting normal cells. Polygonumins A also showed promising activity as an HIV-1 protease inhibitor with 56% relative inhibition. Molecular docking results indicated that the compound possesses high binding afnity towards the HIV protease over the low binding free energy range of -10.5 to -11.3kcal/mol. P. minus is used in Malaysian traditional medicine for the treatment of tumour cells. This is the frst report on the use of P. minus as an HIV-1 protease inhibitor

Water temperature and stocking density for longhour transportation of hybrid grouper Epinephelus fuscoguttatus x E. lanceolatus

This study aims to investigate the effect of water temperature and stocking density in a longhour transportation of hybrid grouper [tiger grouper (Epinephelus fuscoguttatus) x giant grouper (E. lanceolatus)]. A factorial design of three different water temperature levels (16, 18 and 21°C) and three different stocking density levels (120, 180 and 240 g L -1 ) was tested in this experiment. The experiment was conducted using a 10 L rectangular aquarium, equipped with a water chiller and aeration to maintain the water temperature at the required level. The hybrid grouper (average body weight: 5.11±0.34 g) were placed in each aquarium with different stocking density levels for a 12-hour period. The results show that the survival of fish was significantly lower (p < 0.05) at a lower water temperature level (16°C; 50.2%), while there is no significant difference for the other temperature levels considered, 18 and 21°C. The results also show that the lowest water temperature had a significantly (p < 0.05) lower pH value in each stocking density. The glycogen content in fish liver was significantly higher (p < 0.05) at a low water temperature and low stocking density. A similar trend can be observed on the dissolved oxygen of water during the experiment. Moreover, the ammonia concentration was significantly (p < 0.05) higher at a higher water temperature and a higher stocking density. The findings in the present study suggest that hybrid grouper can be economically transported for a long hour journey at a high stocking density (240 g L -1 ), with a water temperature level between 18 to 21°C

Investigating transportation research based on social media analysis: A systematic mapping review

Social media is a pool of users’ thoughts, opinions, surrounding environment, situation and others. This pool can be used as a real-time and feedback data source for many domains such as transportation. It can be used to get instant feedback from commuters; their opinions toward the transportation network and their complaints, in addition to the traffic situation, road conditions, events detection and many others. The problem is in how to utilize social media data to achieve one or more of these targets. A systematic review was conducted in the field of transportation-related research based on social media analysis (TRRSMA) from the years between 2008 and 2018; 74 papers were identified from an initial set of 703 papers extracted from 4 digital libraries. This review will structure the field and give an overview based on the following grounds: activity, keywords, approaches, social media data and platforms and focus of the researches. It will show the trend in the research subjects by countries, in addition to the activity trends, platforms usage trend and others. Further analysis of the most employed approach (Lexicons) and data (text) will be also shown. Finally, challenges and future works are drawn and proposed

Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats

In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security

The Role of Vehicular Cloud Computing in Road Traffic Management: A Survey

The vehicular cloud computing (VCC) is an emerging technology that changed the vehicular communication and underlying traffic management applications. The underutilized resources of vehicles can be shared with other vehicles over the VANET to manage the road traffic more efficiently. The cloud computing and its capability of integrating and sharing resources, plays potential role in the development of traffic management systems (TMSs). This paper reviews the VCC based traffic management solutions to analyze the role of VCC in road traffic management. Particularly, an analysis of VANET based and VCC based TMSs is presented. To explore, the VANET infrastructure and services, a comparison of VCC based TMSs is provided. A taxonomy of vehicular clouds is presented, in order to identify and differentiate the type of vehicular cloud’s integration. Potential future challenges and their solutions in respect of emerging technologies are also discussed. The VCC is envision to play an important role in further development of intelligence transportation system
