More than a decade has elapsed since the historic inaugural meeting of the World Society for Pediatric and Congenital Heart Surgery (WSPCHS). The leaders and participants of this event were motivated and inspired by the prospect of a new era of global communication in the field of congenital heart disease. Their mission, galvanized by the ratification of the society’s constitution, directed new members to promulgate efforts to “promote the highest quality of comprehensive cardiac care to all patients with congenital heart disease across the globe,” with a message that would be realized for decades to come [1].
Recent Studies on the Health Benefits of Omega-3 Polyunsaturated Fatty Acids
James D. Richards,Taichi Inui,Peter Van Dael 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10
Long-chain omega-3 polyunsaturated fatty acids (n-3 LCPUFAs), in particular docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA), are nutrients involved in several metabolic and physiological processes. They have been extensively studied for their effects in human nutrition and health. This talk will provide a brief overview on metabolism, sources, dietary intake, and global intake and status of n-3 LCPUFA. Recommendations from expert groups and scientific authorities for n-3 LCPUFA intakes for different age groups as well as specific physiological conditions will be discussed. Evidence for n-3 LCPUFA in supporting a wide variety of health benefits, in several different populations/life stages, will be reviewed. These benefits include positive effects with respect to heart health; neurodevelopment in infants (when combined with arachidonic acid in appropriate levels and ratios); cognition, and depression/mood including in older adults; support of immune function; as well as the most recent data on the important role these fatty acids play in reducing incidence of early preterm birth. The totality of available data support multiple roles of n-3 LCPUFAs on a diversity of positive health effects across the entirety of the lifespan.
Trace Mineral Nutrition in Poultry and Swine

Trace minerals such as zinc, copper, and manganese are essential cofactors for hundreds of cellular enzymes and transcription factors in all animal species, and thus participate in a wide variety of biochemical processes. Immune development and response, tissue and bone development and integrity, protection against oxidative stress, and cellular growth and division are just a few examples. Deficiencies in trace minerals can lead to deficits in any of these processes, as well as reductions in growth performance. As such, most animal diets are supplemented with inorganic and/or organic forms of trace minerals. Inorganic trace minerals (ITM) such as sulfates and oxides form the bulk of trace mineral supplementation, but these forms of minerals are well known to be prone to dietary antagonisms. Feeding high-quality chelated trace minerals or other classes of organic trace minerals (OTM) can provide the animal with more bioavailable forms of the minerals. Interestingly, many, if not most, published experiments show little or no difference in the bioavailability of OTMs versus ITMs. In some cases, it appears that there truly is no difference. However, real differences in bioavailability can be masked if source comparisons are not made on the linear portion of the dose-response curve. When highly bioavailable chelated minerals are fed, they will better supply the biochemical systems of the cells of the animal, leading to a wide variety of benefits in both poultry and swine. Indeed, the use of certain chelated trace minerals has been shown to enhance mineral uptake, and improve the immune response, oxidative stress management, and tissue and bone development and strength. Furthermore, the higher bioavailability of these trace minerals allows the producer to achieve similar or improved performance, at reduced levels of trace mineral inclusion.
Nonlinear response of mid-latitude weather to the changing Arctic
Overland, James E.,Dethloff, Klaus,Francis, Jennifer A.,Hall, Richard J.,Hanna, Edward,Kim, Seong-Joong,Screen, James A.,Shepherd, Theodore G.,Vihma, Timo Nature Publishing Group, a division of Macmillan P 2016 Nature climate change Vol.6 No.11
<P>Are continuing changes in the Arctic influencing wind patterns and the occurrence of extreme weather events in northern mid-latitudes? The chaotic nature of atmospheric circulation precludes easy answers. The topic is a major science challenge, as continued Arctic temperature increases are an inevitable aspect of anthropogenic climate change. We propose a perspective that rejects simple cause-and-effect pathways and notes diagnostic challenges in interpreting atmospheric dynamics. We present a way forward based on understanding multiple processes that lead to uncertainties in Arctic and mid-latitude weather and climate linkages. We emphasize community coordination for both scientific progress and communication to a broader public.</P>

The Wolbachia bacterium is known to induce reproductive anomalies in various insect taxa such as cytoplasmic incompatibility, feminization, male killing and parthenogenesis. It is hypothesized that the degree of reproductive anomalies is dependent on the bacterial infection density. In this study, we attempted to test the hypothesis using the tiny egg wasp, Trichogramma kaykai that has served as the model system of parthenogenesis where an unfertilized egg develops into a female due to the bacterial infection. So far this is only found in haplodiploid organisms. The results show that 1) as mothers aged, they started producing male offspring, 2) the sex ratio was negatively correlated with the bacterial infection density, 3) female offspring were more than six times heavily infected with Wolbachia than male offspring in the species. In conclusion, female offspring production, parthenogenesis, is as a function of the Wolbachia bacterial density in this species.

Purpose Protoplasmic tubes of Physarum polycephalum,also know as Physarum Wires (PW), have been previouslysuggested as novel bio-electronic components. Until recently,practical examples of electronic circuits using PWs have beenlimited. These PWs have been shown to be self repairing,offering significant advantage over traditional electroniccomponents. This article documents work performed toproduce practical circuits using PWs. Methods We have demonstrated through manufacture andtesting of hybrid circuits that PWs can be used to produce avariety of practical electronic circuits. A plurality of differentapplications of PWs have been tested to show the universalityof PWs in analogue and digital electronics. Results Voltage dividers can be produced using a pair ofPWs in series with an output voltage accurate to within 12%. PWs can also transmit analogue and digital data with afrequency of up to 19 kHz, which with the addition of abuffer, can drive high current circuits. We have demonstratedthat PWs can last approximately two months, a 4 fold increaseon previous literature. Protoplasmic tubes can be modifiedwith the addition of conductive or magnetic nano-particles toprovide changes in functionality. Conclusions This work has documented novel macro-scaledata transmission through biological material; it has advancedthe field of bio-electronics by providing a cheap and easy togrow conducting bio-material which may be used in futurehybrid electronic technology.
