Regional fisheries management: COVID-19 calendars and decision making.

In 2020 the management of transboundary fisheries was severely impacted by the global COVID-19 pandemic. Most annual meetings of regional fisheries and marine management organizations were held virtually, postponed, or cancelled. Even though most organizations managed to meet virtually in 2020, many important decisions were postponed to 2021. Consequently, regional secretariats and delegations face a difficult calendar with substantial agendas and complex decision-making challenges. This commentary provides a brief overview of the virtual meeting processes that have been implemented by regional organisations in response to COVID-19 and provides a calendar of their plans for 2021.

Assessing food security using household consumption expenditure surveys (HCES): a scoping literature review.

OBJECTIVE: To meet some of the UN's seventeen Sustainable Development Goals by 2030, there is a need for more effective policy to reduce food insecurity in low-income and lower-middle-income countries (LMIC). Measuring progress towards these goals requires reliable indicators of food security in these countries. Routinely conducted household consumption and expenditure surveys (HCES) provide potentially valuable and nationally representative data sets for this purpose. The present study aimed to assess methods used to determine national food security status using proxy measures from HCES data in LMIC globally. DESIGN: A scoping literature review was conducted using electronic databases. Of the 929 abstracts identified, a total of twenty articles were reviewed against strict inclusion and exclusion criteria and included for further analysis. RESULTS: Fourteen LMIC globally were represented in the twenty articles. The simplest metric used to indicate food insecurity compared household food expenditure against a level of expenditure considered to be below the poverty line. Data on acquisition of food was commonly converted to available energy for the household using local food composition tables and expressed as a proportion of household total energy requirements. Dietary diversity was also assessed in some studies as well as experience of food insecurity. CONCLUSIONS: The review demonstrated that routinely collected HCES data sets provide a useful resource for the measurement of household food security in often resource-limited LMIC. Standardisation of methods used to assess food security is needed to allow for more useful comparisons between countries, as well as to assess temporal trends.

Fish, food security and health in Pacific Island countries and territories: a systematic literature review.

BACKGROUND: Pacific Island countries and territories (PICTs) face a double burden of disease, with a high prevalence of household food insecurity and childhood micronutrient deficiencies, accompanied by a burgeoning increase in adult obesity, diabetes and heart disease. METHODS: A systematic literature review was undertaken to assess whether increased availability of, and access to, fish improves a) household food security and b) individual nutritional status. RESULTS: A total of 29 studies were reviewed. Fourteen studies identified fish as the primary food source for Pacific Islanders and five studies reported fish/seafood as the primary source of dietary protein. Fish consumption varied by cultural sub-region and Pacific Island countries and territories. Fish consumption and nutritional status was addressed in nine studies, reporting moderate iodine deficiency in Vanuatu where only 30% of participants consumed mostly fresh fish. Similarly, the degree to which Pacific Islanders depended on fishing for household income and livelihood varied between and within PICTs. For more economically developed countries, household income was derived increasingly from salaried work and dependency on fishing activities has been declining. CONCLUSIONS: Fishing remains a major contributor to food security in PICTs, through subsistence production and income generation. However, there is a paucity of research aimed at assessing how maintaining and/or improving fish consumption benefits the diets and health of Pacific Islanders as they contend with the ongoing nutrition transition that is characterised by an increasing demand for packaged imported foods, such as canned meats, instant noodles, cereals, rice, and sugar-sweetened beverages, with subsequent decreased consumption of locally-produced plants and animals.

Green Approach toward Triazole forming Reactions for Developing Anticancer Drugs.

Compounds containing triazole have many significant applications in the dye and ink industry, corrosion inhibitors, polymers, and pharmaceutical industries. These compounds possess many antimicrobial, antioxidant, anticancer, antiviral, anti-HIV, antitubercular, and anticancer activities. Several synthetic methods have been reported for reducing time, minimizing synthetic steps, and utilizing less hazardous and toxic solvents and reagents to improve the yield of triazoles and their analogues synthesis. Among the improvement in methods, green approaches towards triazole forming biologically active compounds, especially anticancer compounds, would be very important for pharmaceutical industries as well as global research community. In this article, we have reviewed the last five years of green chemistry approaches on click reaction between alkyl azide and alkynes to install 1,2,3-triazole moiety in natural products and synthetic drug-like molecules, such as in colchicine, flavanone cardanol, bisphosphonates, thiabendazoles, piperazine, prostanoid, flavonoid, quinoxalines, C-azanucleoside, dibenzylamine, and aryl-azotriazole. The cytotoxicity of triazole hybrid analogues was evaluated against a panel of cancer cell lines, including multidrug-resistant cell lines.

Electrospinning of cyanoacrylate tissue adhesives for human dural repair in endonasal surgery.

Cerebral spinal fluid (CSF) leakage is a major postoperative complication requiring surgical intervention, resulting in prolonged healing and higher costs. Biocompatible polymers, such as cyanoacrylates, are currently used as tissue adhesives for closing surgical defects and incisions. Coupling these polymers with nanofiber technology shows promising results for generating nanofibers used in wound care, tissue engineering, and drug delivery. Fiber membranes formed by electrospinning of n-octyl-2-cyanoacrylate (NOCA) are investigated for in situ dural closures after neurosurgery to improve the quality of the closure and prevent post-surgical CSF leaks. Electrospun NOCA fiber membranes showed significantly higher sealing capabilities of defects in human dura, with an average burst pressure of 149 mmHg, compared with that of an FDA-approved common dural sealant that had an average burst pressure of 37 mmHg. In this study, microfabrication of NOCA fibers demonstrates a promising technique for dural repairs.

Correlation of Trace Silicone Contamination Analyses on Epoxy Composites Using X-ray Photoelectron Spectroscopy (XPS) and Laser-Induced Breakdown Spectroscopy (LIBS).

Surface treatment and surface characterization techniques are critical to ensure that adherends are chemically activated and free of contaminants before adhesive bonding. Silicone contamination from mold release agents and other sources can interfere with interfacial bonding, decreasing the durability and performance of bonded composite structures. It is necessary to have tools and methods that can be used in a production environment to reliably detect low levels of contaminants in a rapid, simple, and cost-effective manner to improve bond reliability. In this work, surface characterization of carbon fiber reinforced polymer (CFRP) composites with epoxy matrix was performed using laser-induced breakdown spectroscopy (LIBS), and the results were compared with those obtained from X-ray photoelectron spectroscopy (XPS). Laser-induced breakdown spectroscopy offers many advantages over XPS in terms of ease of use, sample preparation, and real-time results. The objective of the comparison was to study the sensitivity of LIBS and to investigate the quantification of the surface species measured by LIBS. Another objective was to assess the reliability of each technique for surface contaminant characterization. The as-processed CFRP panels had trace surface silicone contamination from the fabrication process, the source of which was not investigated. The composites were laser treated at select average laser power levels, resulting in varying levels of contamination reduction. The Si atomic percentage measurements using XPS were conducted on both control and laser-ablated surfaces. The results showed an excellent correlation in Si concentration between the two techniques.

Sexual Assault Victimization Among Female Undergraduates During Study Abroad: A Single Campus Survey Study.

Almost all research on sexual assault victimization among undergraduate university students pertains to incidents that occur on domestic college and university campuses. The purpose of the present study was to investigate the prevalence of sexual assault victimization and related factors among undergraduates in the context of study-abroad programs. Two hundred eight female students (52% response rate) from a small university in the northeastern United States who had recently studied abroad responded to an online survey containing measures of sexual assault, posttraumatic stress responses (PSR), and alcohol consumption. Almost 19% of the respondents indicated one or more types of sexual assault victimization. Approximately 17% reported non-consensual sexual touching, 7% attempted rape, 4% rape, with 9% reporting attempted rape or rape. As in domestic studies, victimization in this sample was related positively to alcohol consumption and PSR. Use of force was the most frequently reported perpetrator tactic. In sum, the high rates of sexual assault victimization reported by this sample during study abroad replicate previous findings. This context requires further attention from sexual assault researchers, especially given the increasing numbers of university students engaging in study abroad, and from campus support personnel who may be unaware of the likelihood of assault in this context.
