TL;DR: This study validated a model and identified a deep understanding of structural relationships between the selected variables among Chinese nurses' perceived social support, self-efficacy, work stress, and burnout.
Abstract: Aims To establish a model and identify structural relationships between Chinese nurses' perceived social support, self-efficacy, work stress and burnout. Background The prevalence of burnout among nurses tends to be high worldwide. A better understanding of relationships between the study variables can help hospital managers apply effective programmes to reduce burnout. However, no studies have identified the structural relationships between these variables in one model, simultaneously. Methods We conducted a cross-sectional survey to complete questionnaires from 444 nurses working in three Chinese general tertiary hospitals. The proposed model was examined by structural equation modelling. Results The proposed model was partially supported by empirical data. The total effect of work stress on burnout was large. Both work stress and the perceived social support moderately and directly affected burnout. Work stress also indirectly affected burnout through perceived social support. Work stress directly influenced perceived social support and self-efficacy. Perceived social support directly affected self-efficacy. However, self-efficacy did not directly influence burnout. Conclusions This study validated a model and identified a deep understanding of structural relationships between the selected variables among Chinese nurses. Implications for nursing management Apart from reducing work stressors, hospital managers should utilize more social support strategies when designing intervention programmes to reduce burnout.

TL;DR: Exosome-based nanocarriers have a huge prospect in overcoming many hindrances encountered in drug and gene delivery, and special focus has been placed on the advantages of exosomes in delivering various cargoes and in treating obstinate diseases.
Abstract: Recent decades have witnessed the fast and impressive development of nanocarriers as a drug delivery system. Considering the safety, delivery efficiency and stability of nanocarriers, there are many obstacles in accomplishing successful clinical translation of these nanocarrier-based drug delivery systems. The gap has urged drug delivery scientists to develop innovative nanocarriers with high compatibility, stability and longer circulation time. Exosomes are nanometer-sized, lipid-bilayer-enclosed extracellular vesicles secreted by many types of cells. Exosomes serving as versatile drug vehicles have attracted increasing attention due to their inherent ability of shuttling proteins, lipids and genes among cells and their natural affinity to target cells. Attractive features of exosomes, such as nanoscopic size, low immunogenicity, high biocompatibility, encapsulation of various cargoes and the ability to overcome biological barriers, distinguish them from other nanocarriers. To date, exosome-based nanocarriers delivering small molecule drugs as well as bioactive macromolecules have been developed for the treatment of many prevalent and obstinate diseases including cancer, CNS disorders and some other degenerative diseases. Exosome-based nanocarriers have a huge prospect in overcoming many hindrances encountered in drug and gene delivery. This review highlights the advances as well as challenges of exosome-based nanocarriers as drug vehicles. Special focus has been placed on the advantages of exosomes in delivering various cargoes and in treating obstinate diseases, aiming to offer new insights for exploring exosomes in the field of drug delivery.

TL;DR: This review on the small-molecule EGFR T790M inhibitors, along with their discovery strategies, will assist in the design of future T790m-containing EGFR inhibitors with high levels of selectivity over WT EGFR, broad kinase selectivity, and desirable physicochemical properties.
Abstract: Because of the development of drug-resistance mutations, particularly the “gatekeeper” threonine790-to-methionine790 (T790M) mutation in the ATP-binding pocket of the epidermal growth factor receptor (EGFR), the current generation of EGFR tyrosine kinase inhibitors lost their clinical efficacy. Recently, a large number of small-molecule inhibitors with striking inhibitory potency against EGFR mutants with the T790M change have been identified. In particular, the inhibitors rociletinib and osimertinib, which can selectively target both sensitizing mutations and the T790M resistance while sparing the wild-type (WT) form of the receptor, have been designated as breakthrough therapies in the treatment of mutant non-small-cell lung cancer (NSCLC) by the U.S. FDA in 2014. We hope that this review on the small-molecule EGFR T790M inhibitors, along with their discovery strategies, will assist in the design of future T790M-containing EGFR inhibitors with high levels of selectivity over WT EGFR, broad kinase select...

TL;DR: Exosomal MALAT1 promoted the malignant behavior of CRC cells by sponging miR-26a/26b via regulating FUT4 and activating PI3K/Akt/mTOR pathway.
Abstract: Exosomes are vesicles of endocytic origin released by various cell types and emerging as important mediators in tumor cells. Human metastases-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA known to promote cell proliferation, metastasis, and invasion in colorectal cancer (CRC). The expression of MALAT1 was analyzed in CRC using qRT-PCR. FUT4 and fucosylation levels were detected in CRC clinical samples and CRC cell lines by immunofluorescent staining, western blot and lectin blot analysis. CRC derived exosomes were isolated and used to examine their tumor-promoting effects in vitro and in vivo. The invasive and metastatic abilities of primary CRC cells were enhanced after exposure to exosomes derived from highly metastatic CRC cells, which increased the fucosyltransferase 4 (FUT4) levels and fucosylation not by directly transmitting FUT4 mRNA. Exosomal MALAT1 increased FUT4 expresssion via sponging miR-26a/26b. Furthermore, MALAT1/miR-26a/26b/FUT4 axis played an important role in exosome-mediated CRC progression. Exosomal MALAT1 also mediated FUT4-associated fucosylation and activated the PI3K/AKT/mTOR pathway. These data indicated that exosomal MALAT1 promoted the malignant behavior of CRC cells by sponging miR-26a/26b via regulating FUT4 and activating PI3K/Akt/mTOR pathway.
