    The Surf Foot project was created to resolve the challenges faced by Dana Cummings, a former Marine and transtibial left leg amputee, while surfing. Dana is a competitive surfer who first picked up the sport after he lost his leg. He currently utilizes a carbon fiber prosthetic leg when surfing. However, this prosthetic is not ideal for Dana as he often slips while standing up on his surfboard. As such, Dana would like a new non-slip prosthetic leg so that he can further pursue his passion of competitive surfing. Our team, which consisted of four engineering students attending Cal Poly, San Luis Obispo, was sponsored by the QL+ organization. Over the course of three quarters, we worked to research, design, manufacture, and test a prototype that would meet Dana’s requirements. After several months of brainstorming and conceptualizing, we designed a prosthetic leg made from five main components. These components include two pieces of carbon fiber which together serve as a leg, two rubber components intended to serve as a non-slip sole for the prosthetic, and an adapter that would allow Dana to attach the prosthetic to the socket he uses when surfing. Unfortunately, due to the closure of on-campus facilities that resulted from the COVID-19 pandemic, our team was unable to complete the manufacturing and in-person testing of the prosthetic we designed. Instead, we compiled a list of in-depth instructions regarding the planned manufacturing process and testing of our design so that a future QL+ team could complete our project once campus facilities reopen. Although we were unable to produce a final product, our team is confident that our design will eliminate Dana’s problem of slipping while surfing, thus enabling him to further pursue surfing as a competitive sport

    The SCOUT project is based on the use of multiple innovative and low impact technologies for the protection of space control ground stations and the satellite links against physical and cyber-attacks, and for intelligent reconfiguration of the ground station network (including the ground node of the satellite link) in the case that one or more nodes fail. The SCOUT sub-system devoted to physical attacks protection, SENSNET, is presented. It is designed as a network of sensor networks that combines DAB and DVB-T based passive radar, noise radar, Ku-band radar, infrared cameras, and RFID technologies. The problem of data link architecture is addressed and the proposed solution described

    Epigenetic control of alternative mRNA processing at the imprinted Herc3/Nap1l5 locus

    Get PDF
    Alternative polyadenylation increases transcriptome diversity by generating multiple transcript isoforms from a single gene. It is thought that this process can be subject to epigenetic regulation, but few specific examples of this have been reported. We previously showed that the Mcts2/H13 locus is subject to genomic imprinting and that alternative polyadenylation of H13 transcripts occurs in an allele-specific manner, regulated by epigenetic mechanisms. Here, we demonstrate that allele-specific polyadenylation occurs at another im-printed locus with similar features. Nap1l5 is a retrogene expressed from the paternally inherited allele, is situated within an intron of a ‘host ’ gene Herc3, and overlaps a CpG island that is differen-tially methylated between the parental alleles. In mouse brain, internal Herc3 polyadenylation sites upstream of Nap1l5 are used on the pater-nally derived chromosome, from which Nap1l5 is expressed, whereas a downstream site is used more frequently on the maternally derived chromo-some. Ablating DNA methylation on the maternal allele at the Nap1l5 promoter increases the use of an internal Herc3 polyadenylation site and alters exon splicing. These changes demonstrate the influ-ence of epigenetic mechanisms in regulating Herc3 alternative mRNA processing. Internal Herc3 polyadenylation correlates with expression levels of Nap1l5, suggesting a possible role for transcrip-tional interference. Similar mechanisms may regulate alternative polyadenylation elsewhere in the genome

    Background Trauma is a significant public health problem in Latin America (LA), contributing to substantial death and disability in the region. Several LA countries have implemented trauma registries and injury surveillance systems. However, the region lacks an integrated trauma system. The consensus conference’s goal was to integrate existing LA trauma data collection efforts into a regional trauma program and encourage the use of the data to inform health policy. Methods We created a consensus group of 25 experts in trauma and emergency care with previous data collection and injury surveillance experience in the LA. region. Experts participated in a consensus conference to discuss the state of trauma data collection in LA. We utilized the Delphi method to build consensus around strategic steps for trauma data management in the region. Consensus was defined as the agreement of ≄ 70% among the expert panel. Results The consensus conference determined that action was necessary from academic bodies, scientific societies, and ministries of health to encourage a culture of collection and use of health data in trauma. The panel developed a set of recommendations for these groups to encourage the development and use of robust trauma information systems in LA. Consensus was achieved in one Delphi round. Conclusions The expert group successfully reached a consensus on recommendations to key stakeholders in trauma information systems in LA. These recommendations may be used to encourage capacity building in trauma research and trauma health policy in the region

This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.Background: Parkinson’s disease is characterized by the presence of cytoplasmic inclusions, known as Lewy bodies, containing both aggregated α-synuclein and its interaction partner, synphilin-1. While synphilin-1 is known to accelerate inclusion formation by α-synuclein in mammalian cells, its effect on cytotoxicity remains elusive. Methodology/Principal Findings: We expressed wild-type synphilin-1 or its R621C mutant either alone or in combination with α-synuclein in the yeast Saccharomyces cerevisiae and monitored the intracellular localization and inclusion formation of the proteins as well as the repercussions on growth, oxidative stress and cell death. We found that wild-type and mutant synphilin-1 formed inclusions and accelerated inclusion formation by α-synuclein in yeast cells, the latter being correlated to enhanced phosphorylation of serine-129. Synphilin-1 inclusions co-localized with lipid droplets and endomembranes. Consistently, we found that wild-type and mutant synphilin-1 interacts with detergent-resistant membrane domains, known as lipid rafts. The expression of synphilin-1 did not incite a marked growth defect in exponential cultures, which is likely due to the formation of aggresomes and the retrograde transport of inclusions from the daughter cells back to the mother cells. However, when the cultures approached stationary phase and during subsequent ageing of the yeast cells, both wild-type and mutant synphilin-1 reduced survival and triggered apoptotic and necrotic cell death, albeit to a different extent. Most interestingly, synphilin-1 did not trigger cytotoxicity in ageing cells lacking the sirtuin Sir2. This indicates that the expression of synphilin-1 in wild-type cells causes the deregulation of Sir2-dependent processes, such as the maintenance of the autophagic flux in response to nutrient starvation. Conclusions/Significance: Our findings demonstrate that wild-type and mutant synphilin-1 are lipid raft interacting proteins that form inclusions and accelerate inclusion formation of α-synuclein when expressed in yeast. Synphilin-1 thereby induces cytotoxicity, an effect most pronounced for the wild-type protein and mediated via Sir2-dependent processes.This work was supported by grants from IWT-Vlaanderen (SBO NEURO-TARGET), the K.U.Leuven Research Fund (K.U.Leuven BOF-IOF) and K.U.Leuven R&D to JW, a Tournesol grant from Egide (Partenariat Hubert Curien) in France in collaboration with the Flemish Ministry of Education and the Fund of Scientific Research of Flanders (FWO) in Belgium to JW, MCG and LB, a shared PhD fellowship of the EU-Marie Curie PhD Graduate School NEURAD to JW, MCG and LB, grants of the Austrian Science Fund FWF (Austria) to FM and DR (S-9304-B05), to FM and SB (LIPOTOX), and to SB (T-414-B09; Hertha-Firnberg Fellowship) and an EMBO Installation Grant, a Marie Curie IRG, and a grant of the Fundação para a CiĂȘncia e Tecnologia (PTDC/SAU-NEU/105215/2008) to TFO.

    Danos causados ao meio ambiente, animais e ao homem com a utilização de agrotóxico: revisão bibliogråfica / Damage caused environment, animals and man with the use pesticides: bibliographic review

    Get PDF
    Os agrotĂłxicos sĂŁo substĂąncias quĂ­micas, fĂ­sicas e biolĂłgicas que tem como função, o extermĂ­nio de pragas que prejudicam as lavouras. Eram utilizados desde a era cristĂŁ, onde o piretro era o pioneiro em combater insetos que destruĂ­am as plantaçÔes, tambĂ©m eram utilizados o enxofre e o calcĂĄrio. Durante a dĂ©cada de 90 com a “Revolução Verde”, foram intensificados os produtos utilizados na agricultura sendo eles (pesticidas, praguicidas, defensivos agrĂ­colas), começando a chamada, que tinha como função tambĂ©m, acabar com a fome mundial e controlar as pragas, aumento da produção, aumento de lucro, porĂ©m, acontecia o desequilĂ­brio ambiental como: de a contaminação de solo, rios, meio ambiente e de pessoas que sofrem com doenças causadas por agrotĂłxicos. Portanto, o objetivo do presente trabalho foi analisar os danos causados ao meio ambiente, animais e ao homem com a utilização de agrotĂłxico. Assim sendo, os produtos agrĂ­colas tĂȘm uma grande importĂąncia para a produção nas plantaçÔes, e para gerar lucro aos produtores, mas sabemos que mesmo sendo eficientes no controle de pragas, esses produtos causam danos ao homem e ao meio ambiente, como doenças a saĂșde humana e destruição dos solos e rios. Por isso, Ă© um produto que deverĂĄ ser usado conscientemente, para evitar danos ambientais e doenças as pessoas que consomem ou trabalham com esses produtos. Desta forma, o uso incorreto do agrotĂłxico causa sĂ©rios danos ao homem, como intoxicação alimentar, doenças hepĂĄticas, teratogĂȘnicas, respiratĂłrias, deformidades, infertilidade, cĂąncer e envenenamento podendo levar a morte. Deste modo sĂŁo materiais muito importantes para a produção agrĂ­cola, portanto, devem ser utilizados de maneira adequada e consciente para nĂŁo prejudicar a saĂșde animal como intoxicação e futuras doenças
