Optical multiplexing has a large impact in photonics, the life sciences and biomedicine. However, current technology is limited by a 'multiplexing ceiling' from existing optical materials. Here we engineered a class of polyyne-based materials for optical supermultiplexing. We achieved 20 distinct Raman frequencies, as 'Carbon rainbow', through rational engineering of conjugation length, bond-selective isotope doping and end-capping substitution of polyynes. With further probe functionalization, we demonstrated ten-color organelle imaging in individual living cells with high specificity, sensitivity and photostability...

Technical benefits of additives in polymers stand in marked contrast to their associated health risks. Here, a multi-analyte method based on gas chromatography coupled to tandem mass spectrometry (GC-MS/MS) was developed to quantify polymer additives in complex matrices such as low-density polyethylene (LDPE) and isolated human skin layers after dermal exposure ex vivo. That way both technical aspects and dermal exposure were investigated. The effects of polymer additivation on the material were studied using the example of LDPE...

Paediatric palliative care (PPC) endeavours to alleviate the suffering and improve the quality of life of children with serious illnesses and their families. In the past two decades since WHO defined PPC and called for its inclusion in paediatric oncology care, rigorous investigation has provided important insights. For example, the first decade of research focused on end-of-life experiences of the child and the family, underscoring the high prevalence of symptom burden, the barriers to parent-provider concordance with regards to prognosis, as well as the need for bereavement supports...

Despite wishes for and benefits of home deaths, a discrepancy between preferred and actual location of death persists. Provision of home care may be an effective policy response to support home deaths. Using the population-based mortality follow-back study conducted in Nova Scotia, we investigated the associations between home death and formal care at home and between home death and the type of formal care at home. We found (1) the use of formal care at home at the end of life was associated with home death and (2) the use of formal home support services at home was associated with home death among those whose symptoms were well managed...

End-of-life (EOL) tyres and their decomposition present severe environmental concern due to their resistance to moisture, oxygen, natural degradation, etc. Pyrolysis is considered to be the most effective and sustainable process for recycling, due to its eco-friendly process. The current work studied the effect of recycled carbon black (rCB), obtained from the pyrolysis of EOL tyres, on the properties of ethylene propylene diene rubber (EPDM). The rCB was characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and chemical methods...

Roxanne Kirsch, David Munson
ECMO has proven to be a life-saving intervention for a variety of disease entities with a high rate of survival in the neonatal population. However, ECMO requires clinical teams to engage in many ethical considerations. Even with ongoing improvements in technology and expertise, some patients will not survive a course of ECMO. An unsuccessful course of ECMO can be difficult to accept and cause a great deal of angst. These questions can result in real conflict both within the care team, and between the care team and the family...

As palliative care units continue to develop, the provision of end-of-life care for patients with a chronic mental illness needs to be addressed. Aside from the somatic comorbidities to which these patients are particularly exposed and in view of the specificity of psychiatric treatment, the forms of end-of-life support for a patient with schizophrenia are described here, based on the experience of a psychiatric unit in the Var region.

Lysozyme is a relatively small enzyme with different biological activities, which is found in tears, saliva, egg white, and human milk. In the study, the anti-HIV-1 activity of lysozymes purified from quail, Meleagris, and hen egg white has been determined. For this end, a time-of-drug-addition assay was performed to identify the target of anti-HIV-1 agents and for determination of probable anti HIV-1 mechanism of the studied lysozyme, the binding affinity of the lysozymes to the human CD4 receptor was studied by molecular docking method...

Transient epileptic amnesia (TEA) is an epileptic syndrome characterized by recurrent, brief episodes of amnesia. Patients with TEA often complain of interictal (between attacks) retention deficits, characterised by an 'evaporation' of memories for recent events over days to weeks. Clinical tests of anterograde memory often fail to corroborate these complaints as TEA patients commonly perform within the normal range after the standard 10-30-min delay period. Modified laboratory tests that include a 1-3 week delay period frequently reveal clear evidence of 'accelerated long-term forgetting' (ALF)...

Cryptosporidium is a ubiquitous protozoan parasite causing gastrointestinal disorder in various hosts worldwide. The disease is self-limiting in the immunocompetent but life-threatening in immunodeficient individuals. Investigations to find an effective drug for the complete elimination of the Cryptosporidium infection are ongoing and urgently needed. The current study was undertaken to examine the anti-cryptosporidial efficacy of curcumin in experimentally infected mice compared with that of paromomycin. Oocysts were isolated from a pre-weaned dairy calf and identified as Cryptosporidium parvum using a nested- polymerase chain reaction (PCR) on Small subunit ribosomal ribonucleic acid (SSU rRNA) gene and sequencing analysis...

Advance directives such as living wills and health care powers of attorney are important documents that offer patients ways to avoid unwanted care when they are unable to express their wishes. Although health care professionals have increased focus on advance care planning in recent years, approximately two thirds of American adults do not have advance medical directives. In addition, 90% of individuals believe that talking to loved ones about end-of-life wishes is important, but only 27% have done so. It is important for nurses to understand the complex factors that influence how individuals make health care decisions and identify ways to encourage conversations with family, friends, and health care providers to help clarify patients' wishes for endof-life care...
