How these perspectives inform the perception of workplace uncongeniality for clinicians contributes greater understanding of the factors contributing to adversarial relationships between clinicians and managers.

This article is among the few papers that discuss interactions with management from the perspective of clinical staff in healthcare. How these perspectives inform the perception of workplace uncongeniality for clinicians contributes greater understanding of the factors contributing to adversarial relationships between clinicians and managers.A challenge in the production of recombinant Adeno-Associated Virus (AAV) for gene therapies is the presence of capsids that lack the required gene of interest. The impact of these empty vectors in therapies is not fully understood, however the ability to control the ratio of empty to full particles, which contain the genetic payload, is a necessary step in the purification of these viruses. In this study, a novel anion exchange chromatography elution method for enrichment of full AAV particles is demonstrated. A step gradient with small conductivity increases of around 1 mS cm-1 provides more efficient separation of empty and full AAV serotype 5 across membrane media as compared to conventional linear gradient method. The use of this approach in optimizing a simpler method for manufacturing processes and scalability to a larger chromatographic volume is explored. With this approach, the authors achieved greater than 4-fold enrichment of full capsids, to give a total of ≈50%-60% full capsids, using a 25 mM Bis-Tris Propane pH 9.0 buffer system with NaCl as the eluting salt. Results suggest that this elution method can be implemented into a scalable process and can provide insight into development of elution methods for other AAV serotypes.

Emergence of new treatments for spinal muscular atrophy type 1 (SMA1) has led to dramatic improvements in respiratory failure and survival. However, these "treated" patients sustain major problems in other organ systems, which may directly or indirectly affect their respiratory function. We observed three main nonrespiratory manifestations in these patients comprised of facial deformities, feeding problems, and spinal deformities.

To investigate these three main sequelae in nusinersen-treated SMA1 patients.

Data on nusinersen-treated SMA1 patients were prospectively collected throughout a 3-year period, with special focus upon nonrespiratory features of the disease.

Twenty nusinersen-treated SMA1 patients were included (eight males, median age 13.5 months, interquartile range 4-56.2 months), among whom 17 survived after 3 years of follow-up. At follow-up, 15 (88%) patients were diagnosed with facial weakness, hypoplasia, or deformity. All but one patient (94%) were fed invasively by percutaneous endoscopic gastrostomy or nasogastric tube feeding. Four patients (25%) had maintained oral feeding in parallel to gastrostomy feeding and had clinical and radiologic evidence of aspirations. Fifteen (88%) patients were diagnosed with scoliosis, of whom seven had undergone or were scheduled to undergo corrective surgery.

Nusinersen-treated SMA1 patients may sustain facial deformities, feeding problems, and severe scoliosis, all of which affect their respiratory system. Strict surveillance of these complications is essential to avoid further respiratory morbidity.

A total of 30 pairs of NSCLC tissues and matched adjacent normal tissues were used to evaluate the expression of FOXP4-AS1 and miR-3184-5p. Cell proliferation was assessed by CCK-8 assay and colony formation assay. Cell apoptosis was measured by flow cytometry. Bioinformatic analysis and luciferase reporter assay were performed to determine the regulatory relationship among FOXP4-AS1, miR-3184-5p and EIF5A. The xenograft tumor model was constructed to confirm the function of FOXP4-AS1 in NSCLC progression. The results showed that FOXP4-AS1 was upregulated and miR-3184-5p was downregulated in NSCLC tissues and cell lines. Downregulation of FOXP4-AS1 significantly reduced cell proliferation and induced apoptosis of NSCLC cells in vitro. FOXP4-AS1 could regulated the expression of EIF5A by binding to miR-3184-5p. Rescue experiments showed that downregulation of miR-3184-5p or overexpression of EIF5A obviously attenuated the inhibitory effects of si-FOXP4-AS1 on cell proliferation, as well as the stimulating effects on cell apoptosis. Moreover, knockdown of FOXP4-AS1 could efficiently inhibited tumor development of NSCLC in vivo. Downregulation of FOXP4-AS1 attenuated the progression of NSCLC by regulating miR-3184-5p and EIF5A.Single atom catalysts (SACs) have received a great deal of attention due to their extremely high active site utilization and superior activities. The exploration of metal SACs has been carried out by screening the elemental periodic table from first-row to second-row, and even third-row transition metals. However, Re SACs have not been reported, even if Re metal sites also play essential roles in catalyzing many important reactions. The construction of Re SACs may maximize Re catalytic sites and provide new Re active sites for higher activity. Herein, we used 1,10-phenanthroline to complex Re cations on carbon black, followed by heat treatment to obtain Re SAC. The Re SAC exhibited an oxygen reduction reaction (ORR) half-wave potential of 0.72 V versus reversible hydrogen electrode (RHE) in 0.1 M KOH, superior to Re nanoparticles catalyst (0.67 V vs. RHE). Re SAC exhibited better stability at 0.5 V vs. RHE than Pt/C, showing potential as a new electrocatalyst for ORR.Mechanical stimulation plays in an important role in regulating stem cell differentiation and their release of extracellular vesicles (EVs). In this study, effects of low magnitude hydrostatic pressure (HP) on the chondrogenic differentiation and microvesicle release from human embryonic stem cells (hESCs) and human bone marrow stem cells (hBMSCs) are examined. hESCs were differentiated into chondroprogenitors and then embedded in fibrin gels and subjected to HP (270 kPa, 1 Hz, 5 days per week). hBMSC pellets were differentiated in chondrogenic media and subjected to the same regime. HP significantly enhanced ACAN expression in hESCs. It also led to a significant increase in DNA content, sGAG content and total sGAG/DNA level in hBMSCs. Furthermore, HP significantly increased microvesicle protein content released from both cell types. These results highlight the benefit of HP bioreactor in promoting chondrogenesis and EV production for cartilage tissue engineering.The co-crystallization approach has been used to enhance specific desirable properties of active pharmaceutical ingredients (APIs) such as solubility, dissolution rate, and stability. Solubility is a fundamental property that affects the bioavailability and dosage of the API. The co-crystal approach is one of the emerging methods with the potential for improving the solubility of these drugs. This paper reviews the latest progress on improving the solubility of some antidiabetic drug molecules using the co-crystal approach.Nature creates fascinating self-organized spatiotemporal patterns through the delicate control of reaction-diffusion dynamics. As the primary unit of cortical bone, osteon has concentric lamellar architecture, which plays a crucial role in the mechanical and physiological functions of bone. However, it remains a great challenge to fabricate the osteon-like structure in a natural self-organization way. Taking advantage of the nonequilibrium reaction in hydrogels, a simple mineralization strategy to closely mimic the formation of osteon in a mild physiological condition is developed. By constructing two reverse concentration gradients of ions from periphery to interior of cylindrical hydrogel, spatiotemporal self-organization of calcium phosphate in concentric rings is generated. It is noteworthy that minerals in different layers possess diverse contents and crystalline phases, which further guide the adhesion and spread of osteoblasts on these patterns, resembling the architecture and cytological behavior of osteon. Besides, theoretical data indicates the predominate role of ion concentrations and pH values of solution, in good accordance with experimental results. Independent of precise instruments, this lifelike method is easily obtained, cost-efficient, and effectively imitates the mineral deposition in osteon from a physiochemical view. The strategy may be expanded to develop other functional material patterns via spatiotemporal self-organization.Hybrid microrobots have recently attracted attention due to their ability to combine different energy sources and/or external stimuli for propulsion and performing desired tasks. see more Despite progresses in the past, on-demand speed modulation for hybrid microrobots has not been analyzed in detail. Herein, the influence of surface properties and crystallite size on the propulsion mechanism of Pt/TiO2 chemical/light-driven hybrid microrobots is investigated. The morphology of urchin-like Pt/TiO2 microrobots leads to "on-the-fly" optical brake behavior under UV irradiation. In contrast, smooth Pt/TiO2 microrobots demonstrate accelerated motion in the same conditions. The comparison between two types of microrobots also indicates the significance of a high surface area and a high crystallite size to increase their speed. The results demonstrate the profound impact of surface features for next-generation smart micro/nanorobots with on-demand reaction capability in dynamically changing environments.Studying individuals who recently experienced a romantic reltionship breakup allows us to investigate mood disturbances in otherwise healthy individuals. In our study, we aimed to identify distinct depressive symptom trajectories following breakup and investigate whether these trajectories relate to personality traits and cognitive control. Subjects (n = 87) filled out questionnaires (RRS-NL-EXT trait rumination and NEO-FFI neuroticism) and performed cognitive tasks (trail making test, Stroop task) during a period of 30 weeks. To identify distinct depressive symptom trajectories ('trajectory groups'), we performed K-means clustering on the consecutive (assessed every 2 weeks) Major Depression Inventory scores. This resulted in four trajectory groups; 'resilience', 'fast recovery', 'slow recovery' and 'chronic distress'. The 'slow recovery group' and the 'chronic distress group' were found to have higher neuroticism and trait rumination levels compared to the 'resilience group', and the 'chronic distress group' also had higher neuroticism levels than the 'fast recovery group'. Moreover, the 'chronic distress group' showed worse overall trail making test performance than the 'resilience group'. Taken together, our findings show that distinct patterns of depressive symptom severity can be observed following breakup and that personality traits and cognitive flexibility seem to play a role in these depressive symptom patterns.
