Two new species of Phalangopsis Serville, 1831 (Orthoptera: Grylloidea: Phalangopsidae) from Brazilian Amazon Forest

We describe here two new species of the genus Phalangopsis Serville, 1831 from the Brazilian Amazon Forest. The male genitalia and the female copulatory papilla were described, and a combination of diagnostic characteristics was given to separate both new species from the other described species. The principal morphological characteristics of this genus were discussed.Aqui foram descritas duas espécies novas do gênero Phalangopsis Serville, 1831 da Floresta Amazônica brasileira. A genitália masculina e a papila copulatória feminina são descritas, bem como uma combinação de características diagnósticas para separar ambas as novas espécies das outras espécies descritas. As principais características morfológicas foram discutidas

Do not attempt resuscitation decisions in a cancer centre: addressing difficult ethical and communication issues

Talking to patients about ‘Do Not Attempt Resuscitation’ decisions is difficult for many doctors. Communication about ‘Do Not Attempt Resuscitation’ decisions should occur as part of a wider discussion of treatment goals at an earlier stage in the patient's illness. A doctor should not initiate any treatment, including cardio-pulmonary resuscitation if he/she does not believe it will benefit the patient. An ethical framework is offered which may be of practical help in clarifying decision-making

Digitalized manufacturing logistics in engineer-to-order operations

This is a post-peer-review, pre-copyedit version of an article published in Advances in Production Management Systems. Production Management for the Factory of the Future. APMS 2019. IFIP Advances in Information and Communication Technology, vol. 566. The final authenticated version is available online at: https://doi.org/10.1007/978-3-030-30000-5_71. The high complexity in Engineer-To-Order (ETO) operations causes major challenges for manufacturing logistics, especially in complex ETO, i.e. one-of-a-kind production. Increased digitalization of manufacturing logistics processes and activities can facilitate more efficient coordination of the material and information flows for manufacturing operations in general. However, it is not clear how to do this in the ETO environment, where products are highly customized and production is non-repetitive. This paper aims to investigate the challenges related to manufacturing logistics in ETO and how digital technologies can be applied to address them. Through a case study of a Norwegian shipyard, four main challenges related to manufacturing logistics are identified. Further, by reviewing recent literature on ETO and digitalization, the paper identifies specific applications of digital technologies in ETO manufacturing. Finally, by linking manufacturing logistics challenges to digitalization, the paper suggests four main features of digitalized manufacturing logistics in ETO: (i) seamless, digitalized information flow, (ii) identification and interconnectivity, (iii) digitalized operator support, and (iv) automated and autonomous material flow. Thus, the paper provides valuable insights into how ETO companies can move towards digitalized manufacturing logistics

Silencing cytokeratin 18 gene inhibits intracellular replication of Trypanosoma cruzi in HeLa cells but not binding and invasion of trypanosomes

<p>Abstract</p> <p>Background</p> <p>As an obligatory intracellular parasite, <it>Trypanosoma cruzi</it>, the etiological agent of Chagas' disease, must invade and multiply within mammalian cells. Cytokeratin 18 (CK18) is among the host molecules that have been suggested as a mediator of important events during <it>T. cruzi</it>-host cell interaction. Based on that possibility, we addressed whether RNA interference (RNAi)-mediated down regulation of the CK18 gene could interfere with the parasite life cycle <it>in vitro</it>. HeLa cells transiently transfected with CK18-RNAi had negligible levels of CK18 transcripts, and significantly reduced levels of CK18 protein expression as determined by immunoblotting or immunofluorescence.</p> <p>Results</p> <p>CK18 negative or positive HeLa cells were invaded equally as well by trypomastigotes of different <it>T. cruzi </it>strains. Also, in CK18 negative or positive cells, parasites recruited host cells lysosomes and escaped from the parasitophorous vacuole equally as well. After that, the growth of amastigotes of the Y or CL-Brener strains, was drastically arrested in CK18 RNAi-treated cells. After 48 hours, the number of amastigotes was several times lower in CK18 RNAi-treated cells when compared to control cells. Simultaneous staining of parasites and CK18 showed that in HeLa cells infected with the Y strain both co-localize. Although the amastigote surface protein-2 contains the domain VTVXNVFLYNR previously described to bind to CK18, in several attempts, we failed to detect binding of a recombinant protein to CK-18.</p> <p>Conclusion</p> <p>The study demonstrates that silencing CK18 by transient RNAi, inhibits intracellular multiplication of the Y and CL strain of <it>T. cruzi </it>in HeLa cells, but not trypanosome binding and invasion.</p

Home visit improves knowledge, self-care and adhesion in heart failure: randomized Clinical Trial HELEN-I

OBJECTIVE: To verify the effect of an educative nursing intervention composed of home visits and phone calls on patients' knowledge about the disease, self-care and adhesion to the treatment. METHODS: Randomized clinical trial with patients with recent hospitalization caused by decompensated heart failure. There were two groups: the intervention group, which has received four home visits and four phone calls to reinforce the guidelines during six months of follow up; and the control group, which has received conventional follow up with no visits or phone calls. RESULTS: Two hundred patients were randomized (101 in the intervention group and 99 in the control group). After six months, a significant improvement was observed in self-care and knowledge about the disease in the intervention group (P=0.001 and P<0.001), respectively; the adhesion to the treatment, measured and compared between the groups, was significantly higher in the intervention group (P=0.001). CONCLUSION: the strategy of home visits to patients who were recently hospitalized with decompensated heart failure was effective in improving the outcomes assessed and its implementation deserves to be considered in Brazil aiming at avoiding unplanned hospitalizations.
