Fish Matters: Importance of Aquatic Foods in Human Nutrition and Global Food Supply

Abstract: In a world where nearly 30% of humanity is suffering from malnutrition and over 70% of the planet is covered with water, aquatic foods represent an essential component of the global food basket to improve the nutrition, health, and well being of all peoples. It is not by chance that Japan, the country with one of the world's highest reported life expectancies and lowest incidences of obesity and deaths from heart related illnesses, is also one of the world's top consumers of captured and farmed aquatic animal food products and aquatic plants. According to the FAO, in 2009, total captured and farmed aquatic animal food products accounted for 16.6% of the global population's intake of animal protein, providing more than three billion people with almost 20% of their average per capita intake of animal protein, and 4.3 billion people with at least 15% of such protein. This article reviews the nutritional composition of different farmed and captured aquatic food products and compares these with conventional terrestrial meat products. In addition to the superior nutritional profile and benefits of aquatic animal food products, small-sized marine pelagic fish play an important role in the nutrition of the poor as an affordable and much needed source of high quality animal protein and essential amino acids, omega-3 fatty acids, vitamins, minerals, and trace elements. As one of the best aquatic animal foods from a nutritional perspective, the direct consumption of small pelagic fish should be encouraged and promoted, as apposed to the continued targeted use of these species for reduction into fishmeal and fish oil for use in animal feeds.

Effect of low-power laser irradiation on cell growth and procollagen synthesis of cultured fibroblasts.

Abstract: Background and Objectives: In dentistry, low-power lasers have been used in the treatment of dentin hypersensitivity, gingivitis, periodontitis, and different forms of oral ulcers. This in vitro study focuses on the biostimulation of NIH-3T3 fibroblasts by a low-power Ga–As-pulsed laser. StudyDesign/MaterialsandMethods: We have studied cell growth and procollagen synthesis of cultured fibroblasts submitted to low-power laser irradiation with energy densities varying from 3 to 5 J/cm 2 over a period of 1–6 days. The light source was a 120 mW Ga–As diode laser (l ¼ 904 nm). Growth curves and procollagen immunoprecipitation were obtained. Results: Irradiation of 3 and 4 J/cm 2 increased the cell numbers about threefold to sixfold comparing to control cultures. However, this effect was restricted to a small range of energy densities since 5 J/cm 2 had no effect on cell growth. The energy density of 3 J/cm 2 remarkably increased cell growth, with no effect on procollagen synthesis, as demonstrated by the immunoprecipitation analysis. Conclusions: Our results showed that a particular laser irradiation stimulates fibroblast proliferation, without impairing procollagen synthesis. Lasers Surg.

Taxonomy of the order Mononegavirales: update 2016

Abstract: In 2016, the order Mononegavirales was emended through the addition of two new families (Mymonaviridae and Sunviridae), the elevation of the paramyxoviral subfamily Pneumovirinae to family status (Pneumoviridae), the addition of five free-floating genera (Anphevirus, Arlivirus, Chengtivirus, Crustavirus, and Wastrivirus), and several other changes at the genus and species levels. This article presents the updated taxonomy of the order Mononegavirales as now accepted by the International Committee on Taxonomy of Viruses (ICTV).
