Fish pedicures: Information for the Public

Although the risk of catching an infection as a result of a fish spa pedicure is likely to be very low, it cannot be completely excluded. However, there are certain things you can do to further reduce your risk of catching or spreading an infection when having one of these treatments.Choosing a salonUse your personal judgment: as with all beauty salons, if it looks unsanitary, do not go there for your treatment. If you are very concerned about the cleanliness of a salon you visit, you can report this to your local Environmental Health department, who will be able to perform an inspection of the premises.When having a treatment, a trained member of staff should perform an inspection of your feet both beforehand, to check for any broken skin / infections, and afterwards, to check for signs of bleeding. They should also ask you to wash your feet with soap and water before putting them in the tank, to make sure that any products you have used that could be harmful to the fish are washed away, and to reduce the risk of spreading any infection.Ask your therapist what other procedures the salon has in place to minimise the risk of infection. The Health Protection Agency, England has produced a set of guidelines for salons which, if followed, will ensure any potential risk of infection is kept to an absolute minimum.Before having the treatment The HPA has identified a number of health conditions or prior treatments which may mean that you should not have a fish pedicure. These are:Leg waxing or shaving in last 24 hoursAny open cuts/wounds/abrasions/broken skin on the feet or lower legsInfection on the feet (including athlete's foot, verruca)Psoriasis, eczema or dermatitis affecting the feet or lower legsDiabetes (increased risk of infection)Infection with a blood borne virus such as Hepatitis B or Hepatitis C or HIVAny immune deficiency due to illness or medicationBleeding disorders or on anticoagulant medication (e.g. heparin or warfarinMore information and advice on fish spa pedicures and the full set of guidance can be found on the Health Protection website www.hpa.org.uk

TRADD protein is an essential component of the RIG-like helicase antiviral pathway

Upon detection of viral RNA, the helicases RIG-I and/or MDA5 trigger, via their adaptor Cardif (also known as IPS-1, MAVS, or VISA), the activation of the transcription factors NF-kappaB and IRF3, which collaborate to induce an antiviral type I interferon (IFN) response. FADD and RIP1, known as mediators of death-receptor signaling, are implicated in this antiviral pathway; however, the link between death-receptor and antiviral signaling is not known. Here we showed that TRADD, a crucial adaptor of tumor necrosis factor receptor (TNFRI), was important in RIG-like helicase (RLH)-mediated signal transduction. TRADD is recruited to Cardif and orchestrated complex formation with the E3 ubiquitin ligase TRAF3 and TANK and with FADD and RIP1, leading to the activation of IRF3 and NF-kappaB. Loss of TRADD prevented Cardif-dependent activation of IFN-beta, reduced the production of IFN-beta in response to RNA viruses, and enhanced vesicular stomatitis virus replication. Thus, TRADD is not only an essential component of proinflammatory TNFRI signaling, but is also required for RLH-Cardif-dependent antiviral immune responses

Home parenteral nutrition in children: procedures, experiences and reflections.

This document summarizes the issues raised in a think-tank meeting held by professionals with expertise in pediatric Home Parenteral Nutrition. This nutritional technology enables patients to return home to their family and social environment, improves their quality of life and decreases health-care costs; however, it is complex and requires an experienced nutritional support team. Patient selection is normally made according to their underlying disease, the estimated duration of support and family and social characteristics. The patient''s family must agree to take on caregiver's responsibilities and should be able to perform treatment safely and effectively after receiving proper training from the nutritional support team. Close monitoring must be carried out to ensure tolerance and effectiveness of nutritional support, thereby avoiding complications. This nutritional treatment achieves, in most cases, recovery and intestinal adaptation in varying periods of time. In certain diseases, and when home parenteral nutrition becomes complicated, intestinal transplant may be recommendable, so referral to rehabilitation units and Intestinal Transplantation should be made early on.

Vision-based localization of an underwater robot in a structured environment

This paper presents a vision-based localization approach for an underwater robot in a structured environment. The system is based on a coded pattern placed on the bottom of a water tank and an onboard down looking camera. Main features are, absolute and map-based localization, landmark detection and tracking, and real-time computation (12.5 Hz). The proposed system provides three-dimensional position and orientation of the vehicle along with its velocity. Accuracy of the drift-free estimates is very high, allowing them to be used as feedback measures of a velocity-based low-level controller. The paper details the localization algorithm, by showing some graphical results, and the accuracy of the system

Dam wall detection and tracking using a Mechanically Scanned Imaging Sonar

In dam inspection tasks, an underwater robot has to grab images while surveying the wall meanwhile maintaining a certain distance and relative orientation. This paper proposes the use of an MSIS (mechanically scanned imaging sonar) for relative positioning of a robot with respect to the wall. An imaging sonar gathers polar image scans from which depth images (range & bearing) are generated. Depth scans are first processed to extract a line corresponding to the wall (with the Hough transform), which is then tracked by means of an EKF (Extended Kalman Filter) using a static motion model and an implicit measurement equation associating the sensed points to the candidate line. The line estimate is referenced to the robot fixed frame and represented in polar coordinates (rho&thetas) which directly corresponds to the actual distance and relative orientation of the robot with respect to the wall. The proposed system has been tested in simulation as well as in water tank conditions

The depuration dynamics of oysters (Crassostrea gigas) artificially contaminated with hepatitis A virus and human adenovirus

Within the country of Brazil, Santa Catarina is a major shellfish producer. Detection of viral contamination is an important step to ensure production quality and consumer safety during this process. In this study, we used a depuration system and ultraviolet (UV) disinfection to eliminate viral pathogens from artificially infected oysters and analysed the results. Specifically, the oysters were contaminated with hepatitis A virus (HAV) or human adenovirus type 5 (HAdV5). After viral infection, the oysters were placed into a depuration tank and harvested after 48, 72 and 96 h. After sampling, various oyster tissues were dissected and homogenised and the viruses were eluted with alkaline conditions and precipitated with polyethylene glycol. The oyster samples were evaluated by cell culture methods, as well as polymerase chain reaction (PCR) and quantitative-PCR. Moreover, at the end of the depuration period, the disinfected seawater was collected and analysed by PCR. The molecular assays showed that the HAdV5 genome was present in all of the depuration time samples, while the HAV genome was undetectable after 72 h of depuration. However, viral viability tests (integrated cell culture-PCR and immunofluorescence assay) indicated that both viruses were inactivated with 96 h of seawater recirculation. In conclusion, after 96 h of UV treatment, the depuration system studied in this work purified oysters that were artificially contaminated with HAdV5 and HAV.

Beyond Prejudice : conservation in the City : a case study from Switzerland

Conservation in the city is challenging because of a continued view that the urban realm is antithetical to nature. This was clearly the case when the first Swiss National Park was established at the beginning of the 20th century. New Swiss legislation brought new approaches to the establishment of natural parks, in particular by including human activities as a logical component in their development. In 2010, a Federal think tank discussed opportunities for launching a new kind of park: the Urban Natural Park. This paper reports an analysis of this discussion, together with the study of the literature dealing with conservation in the city and natural parks. It shows that a clear antagonism between city and nature still remains present, reflected in an implicit hierarchy hidden in the designation of natural parks: wild nature is nominated as the best nature; if not wild, the best nature is identified as rural; if neither wild nor rural, nature is thought not to be the concern of natural park policy. The Swiss Biodiversity Strategy implemented in 2012 is a recent recognition of the importance of urban nature for biodiversity conservation. This recognition, however, condemns urban nature to a special status, situated outside the usual framework of conservation management. I conclude by arguing that anti-urban bias must be addressed because it inhibits effective conservation strategy, prevents the identification of existing environmental qualities of cities and, eventually, has negative impacts on biological conservation outside the city because it fosters urban spreading.

Dynamic diagnosis based on interval analytical redundancy relations and signs of the symptoms

A model-based approach for fault diagnosis is proposed, where the fault detection is based on checking the consistencyof the Analytical Redundancy Relations (ARRs) using an interval tool. The tool takes into account the uncertainty in theparameters and the measurements using intervals. Faults are explicitly included in the model, which allows for the exploitation of additional information. This information is obtained from partial derivatives computed from the ARRs. The signs in the residuals are used to prune the candidate space when performing the fault diagnosis task. The method is illustrated using a two-tank example, in which these aspects are shown to have an impact on the diagnosis and fault discrimination, since the proposed method goes beyond the structural methods

Modulaarisen paisunta-astian kehittäminen compact -sarjan teollisuusvaihteeseen

Tämä insinöörityö tehtiin SEW Industrial Gears Oy:lle, joka valmistaa hammasvaihteita teollisuuden eri sovellutuksiin. Työn tavoitteena oli kehittää modulaarinen paisuntaastiasarja compact -sarjan teollisuusvaihteeseen. Työn alkuvaiheessa käytössä oli kahdenlaisia paisunta-astioita: kosteissa oloissa käytettävä suljettu astiamalli ja kuiviin olosuhteisiin soveltuva malli. Koska käytössä oleva suljettu astiamalli oli kallis ja kuivien olosuhteiden mallin käyttö oli rajoitettu, oli uudelle modulaariselle paisunta-astialle selkeä tarve. Uuden astiamallin tuli olla yhteensopiva vaihteen yleisimpien varusteiden ja asennusasentojen kanssa. Lisäksi tavoitteena oli puolittaa uuden konseptin hinta vanhaan verrattuna ja paikata vanhoissa konstruktioissa olleita puutteita. Työ aloitettiin analysoimalla olemassa olevat paisunta-astiatyypit, minkä jälkeen paisuntaastialle ideoitiin uusia ominaisuuksia. Toisessa vaiheessa perehdyttiin modulaariseen järjestelmään sekä öljynpaisunnan teoriaan teollisuusvaihteessa. Viimeisessä vaiheessa tehtiin konseptin varsinainen suunnittelutyö, valittiin astian valmistustapa ja materiaali sekä optimoitiin hinta. Uudesta mallista valmistettiin myös prototyyppi, jotta suunniteltua tuotetta päästiin kokeilemaan myös käytännössä. Näin voitiin varmistaa tuotteen toimivuus. Suunnittelutyön tuloksena saatiin uuden paisunta-astiasarjan piirustukset tarvittavista osista ja kokoonpanoista sekä komponenttistandardi ja myyntiä tukevaa materiaalia. Käytännön osuus antoi tietoa laskelmien oikeellisuudesta sekä öljyn täyttöön ja paisuntaan liittyvistä asioista.

Variability of a peripheral dose among various linac geometries for second cancer risk assessment.

Second cancer risk assessment for radiotherapy is controversial due to the large uncertainties of the dose-response relationship. This could be improved by a better assessment of the peripheral doses to healthy organs in future epidemiological studies. In this framework, we developed a simple Monte Carlo (MC) model of the Siemens Primus 6 MV linac for both open and wedged fields that we then validated with dose profiles measured in a water tank up to 30 cm from the central axis. The differences between the measured and calculated doses were comparable to other more complex MC models and never exceeded 50%. We then compared our simple MC model with the peripheral dose profiles of five different linacs with different collimation systems. We found that the peripheral dose between two linacs could differ up to a factor of 9 for small fields (5 × 5 cm(2)) and up to a factor of 10 for wedged fields. Considering that an uncertainty of 50% in dose estimation could be acceptable in the context of risk assessment, the MC model can be used as a generic model for large open fields (≥10 × 10 cm(2)) only. The uncertainties in peripheral doses should be considered in future epidemiological studies when designing the width of the dose bins to stratify the risk as a function of the dose.

Construcció d'un refugi situat al terme municipal de Vallfogona de Ripollès, pensat com a final d'etapa per a rutes a cavall

Els negocis relacionats amb les activitats de lleure i els esports d’aventura actualment es troben en expansió, buscant majoritàriament el contacte amb la natura. Les rutes a cavall formen part del gran ventall d’opcions, per aquesta qüestió s’ha pensat en construir un refugi utilitzat com a final d’etapa per a rutes a cavall. En la major part del territori, la presència de població humana es manifesta en pobles, viles i ciutats, les quals disposes d’aigua sanitària, corrent elèctric i sistema de clavegueram. Per altra banda en les urbanitzacions o cases aïllades poder gaudir d’aquests serveis suposa una inversió econòmica elevada, que implica la utilització de sistemes alternatius. En el present projecte s’ha triat un emplaçament on portar a terme el final d’etapa amb una sèrie de requisits a complir : bosc a les proximitats, disposar d’un o varis accessos per a vehicles (transport del material d’intendència), tranquil•litat, bones vistes, i cobertura de telèfon mòbil. S’han acceptat les següents limitacions : no disposar de xarxa pública d’electricitat ni d’aigua. I s’han dimensionat les instal•lacions per a un màxim de dotze persones i els seus respectius cavalls. El principal objectiu del projecte és el dimensionament de les necessitats elèctriques, d’aigua i d’aiguacalenta sanitària en condicions autònomes, i utilitzant energies renovables. La valoració de les possibles solucions per condicionar les instal•lacions, i oferir una resposta eficient per la demanda. No és un objectiu específic del treball la potabilització de l’aigua ni el tractament dels residus produïts. S’han aprofitat els diferents desnivells que presenta l’emplaçament triat a l’hora de distribuir les instal•lacions, i s’ha utilitzat un antic cobert de dos pisos ja existent. Com a residència s’ha triat un model de casa prefabricada de muntanya. Com a sistema de subministrament elèctric, s’instal•laran plaques solars fotovoltaiques i un generador de corrent com a sistema auxiliar. La captació d’aigua s’efectuarà a partir d’un pou que es troba en el terreny i de la recollida d el’aigua pluvial, instal•lant dipòsits d’emmagatzemament d’aigua segons les necessitats. S’utilitzarà un equip de cloració per potabilitzar l’aigua de consum utilitzada a la residència. En la producció d’aigua calenta sanitària s’utilitzaran plaques solars tèrmiques i una caldera instantània de gas propà com a suport. Per cuinar s’ha triat una cuina de gas propà i una barbacoa que s’instal•larà a l’exterior. S’instal•larà una llar de foc amb recuperador d’aire a la residència i una fosa sèptica amb un sistema d’infiltració per poder abocar les aigües provinents de la residència. Els fems dels cavalls podran ser utilitzats com adob pel terreny.

DAI/ZBP1 recruits RIP1 and RIP3 through RIP homotypic interaction motifs to activate NF-kappaB.

Detection of viral nucleic acids is central to antiviral immunity. Recently, DAI/ZBP1 (DNA-dependent activator of IRFs/Z-DNA binding protein 1) was identified as a cytoplasmic DNA sensor and shown to activate the interferon regulatory factor (IRF) and nuclear factor-kappa B (NF-kappaB) transcription factors, leading to type-I interferon production. DAI-induced IRF activation depends on TANK-binding kinase 1 (TBK1), whereas signalling pathways and molecular components involved in NF-kappaB activation remain elusive. Here, we report the identification of two receptor-interacting protein (RIP) homotypic interaction motifs (RHIMs) in the DAI protein sequence, and show that these domains relay DAI-induced NF-kappaB signals through the recruitment of the RHIM-containing kinases RIP1 and RIP3. We show that knockdown of not only RIP1, but also RIP3 affects DAI-induced NF-kappaB activation. Importantly, RIP recruitment to DAI is inhibited by the RHIM-containing murine cytomegalovirus (MCMV) protein M45. These findings delineate the DAI signalling pathway to NF-kappaB and suggest a possible new immune modulation strategy of the MCMV.
