be higher risk than others, given the opportunity to improve ED-to-home transitions, EDs and health systems should consider providing additional care transition support to all older adults discharged home from the ED.Molecularly imprinted polymer nanoparticles (MIP NPs) are antibody-like recognition materials prepared by a template-assisted synthesis. MIP NPs able to target biomolecules, like proteins, are under the spotlight for their great potential in medicine, but efficiently imprinting biological templates is still very challenging. Here we propose generating a molecular imprint in single NPs, by photochemically initiating the polymerization from individual protein templates. In this way, each protein molecule tailors itself its own "polymeric dress". For this, the template protein is covalently coupled with a photoinitiator, Eosin Y. Irradiated with light at 533 nm, the Eosin moiety acts as an antenna and transfers energy to a co-initiator (an amine), which generates a radical and initiates polymerization. As a result, a polymer network is forming only around the very template molecule, producing cross-linked NPs of 50 nm, with single binding sites showing high affinity (KD 10-9  m) for their biological target, and selectivity over other proteins.The Tibetan chicken is a native Chinese breed that lives at high elevations and has adapted to the extreme environmental conditions of the Tibetan Plateau. However, its hypoxic adaptation at the gene expression level is unclear. Dibutyryl-cAMP activator Here, we sequenced nine lung transcriptomes of the Tibetan chicken at three developmental stages (5 and 42 weeks and 4.5 years). A total of 1.02 billion clean reads were obtained. We identified 16 012 mRNAs and 6898 lncRNAs. The expression of mRNA showed that nine samples were significantly divided into three clusters, with higher correlation and closer relationship between the 5 and 42 week groups. We identified 399 differentially expressed genes (DEGs) between the 5 and 42 week groups, 3532 DEGs between the 5 week and 4.5 year groups, and 3909 DEGs between the 42 week and 4.5 year groups. The up-regulated DEGs in the 5 week group, compared with 42 week and 4.5 year groups, were enriched in GO terms associated with growth and development, whereas the up-regulated DEGs in the 4.5 year group were mainly enriched in many metabolic-related categories. Moreover, the enrichment results with up-regulated DEGs in the 5 and/or 42 week groups, compared with the 4.5 year group, were associated with hypoxic adaptation, such as oxygen transport, oxygen binding and oxygen carrier activity, and calcium signaling pathway. In addition, we identified 978 high-correlation lncRNA and protein-coding gene pairs, and 524 significant neighboring protein-coding genes were also DEGs. Our results provide new insights into gene expression of lung tissue in Tibetan chickens during the aging process.

The development of novel therapies for the myelodysplastic syndromes (MDS) is hampered by inadequate trial recruitment. Factors contributing to low trial accrual are incompletely understood.

This study analyzed a pooled patient database from institutions of the US MDS Clinical Research Consortium to compare the characteristics of participants in interventional trials with those of patients who did not enroll in a trial.

Data were identified for 1919 patients with MDS, and 449 of these patients (23%) participated in an interventional clinical trial. The median age of all patients was 68years, and 64% were male. Patients who participated in trials were significantly younger than nonparticipants (P=.014), and men were more likely to participate in a trial (71% of trial participants were male, whereas 61% of nonparticipants were; P<.001). Race and ethnicity were not associated with trial enrollment. Patients in more affluent ZIP codes had a higher participation rate (P<.001). Patients with intermediatthe barriers to trial accrual may help investigators and study sponsors to design trials that will accrue more rapidly and augment treatment options for patients with MDS.Students' use of prescription stimulants to enhance study performance is increasingly under the spotlight. Medical guidelines discourage general practitioners (GPs) from prescribing stimulants to students without a diagnosis; yet a considerable proportion of students acquire them from GPs. Building on Eisenberg's theoretical framework on clinical decision-making and Conrad's sociological concept of biomedical enhancement, this study examined the social context of GPs' off-label prescribing decisions for stimulants, using data from 21 semi-structured interviews, including vignettes, undertaken with Flemish GPs. Results identified two groups of GPs (1) hard-liners who strictly follow medical guidelines and who would only prescribe in case of an appropriate diagnosis and (2) context-dependent GPs who would prescribe stimulants depending on the patients' symptoms and extent of need. GPs' decisions depend on one-on-one doctor-patient interactions (i.e. the extent of empathy from the doctor and the extent of assertiveness from the patient); the extent to which GPs define concentration problems as medical problems; GPs' interactions with fellow health care workers; as well as GPs' interaction with the wider community. By disentangling these influences, this paper advances both theoretical and practical understanding of the sociological context in which GPs' off-label prescribing behaviour occurs.Since its eruption in China, novel coronavirus disease (COVID-19) has been reported in most of the countries and territories (>200) of the world with ∼18 million confirmed cases (as of August 3, 2020). In most of the countries, COVID-19 upsurge is uncontrolled with a significant mortality rate. Currently, no treatment effective for COVID-19 is available in the form of vaccines or antiviral drugs and patients are currently treated symptomatically. Although the majority of the patients develop mild symptoms and recover without mechanical ventilation for respiratory management, severe respiratory illness develops in a significant portion of affected patients and may result in death. While the scientific community is working to develop vaccines and drugs against the COVID-19 pandemic, novel alternative therapies may reduce the mortality rate. Recent use of stem cells for critically ill COVID-19 patients in a small group of patients in China and subsequent Emergency Use Authorization of stem cells by Food and Drug Administration to Global Institute of Stem Cell Therapy and Research and Athersys has created excitement among the medical community.
