Synthetic matrices offer a high degree of control and tunability for mimicking extracellular matrix functions of native tissue, allowing the study of disease and development in vitro. In this study, we functionalized degradable poly(ethylene glycol) hydrogels with extracellular matrix (ECM)-sequestering peptides aiming to recapitulate the native ECM composition for culture and maturation of ovarian follicular organoids. We hypothesized that ECM-sequestering peptides would facilitate deposition and retention of cell-secreted ECM molecules, thereby recreating cell-matrix interactions in otherwise bioinert PEG hydrogels.

Controlling T cells spreading, mechanics and activation by micropatterning.

Sci Rep 2021 Mar 24;11(1):6783. Epub 2021 Mar 24.

Adhesion and Inflammation Lab (LAI), Aix Marseille University, LAI UM 61, 13288, Marseille, France.

We designed a strategy, based on a careful examination of the activation capabilities of proteins and antibodies used as substrates for adhering T cells, coupled to protein microstamping to control at the same time the position, shape, spreading, mechanics and activation state of T cells. Once adhered on patterns, we examined the capacities of T cells to be activated with soluble anti CD3, in comparison to T cells adhered to a continuously decorated substrate with the same density of ligands. We show that, in our hand, adhering onto an anti CD45 antibody decorated surface was not affecting T cell calcium fluxes, even adhered on variable size micro-patterns. Read More

Coxsackievirus B3 targets TFEB to disrupt lysosomal function.

Autophagy 2021 Mar 10:1-15. Epub 2021 Mar 10.

Centre for Heart Lung Innovation, St. Paul's Hospital, Vancouver, Canada.

Coxsackievirus B3 (CVB3) is a prevalent etiological agent for viral myocarditis and neurological disorders, particularly in infants and young children. Virus-encoded proteinases have emerged as cytopathic factors that contribute to disease pathogenesis in part through targeting the cellular recycling machinery of autophagy. Although it is appreciated that CVB3 can usurp cellular macroautophagy/autophagy for pro-viral functions, the precise mechanisms by which viral proteinases disrupt autophagy remain incompletely understood.

Gut microbiome pattern reflects healthy ageing and predicts survival in humans.

Nat Metab 2021 02 18;3(2):274-286. Epub 2021 Feb 18.

Institute for Systems Biology, Seattle, WA, USA.

The gut microbiome has important effects on human health, yet its importance in human ageing remains unclear. In the present study, we demonstrate that, starting in mid-to-late adulthood, gut microbiomes become increasingly unique to individuals with age. We leverage three independent cohorts comprising over 9,000 individuals and find that compositional uniqueness is strongly associated with microbially produced amino acid derivatives circulating in the bloodstream.

Pluripotential Risk and Clinical Staging: Theoretical Considerations and Preliminary Data From a Transdiagnostic Risk Identification Approach.

Front Psychiatry 2020 8;11:553578. Epub 2021 Jan 8.

Orygen, Parkville, VIC, Australia.

Most psychiatric disorders develop during adolescence and young adulthood and are preceded by a phase during which attenuated or episodic symptoms and functional decline are apparent. The introduction of the ultra-high risk (UHR) criteria two decades ago created a new framework for identification of risk and for pre-emptive psychiatry, focusing on first episode psychosis as an outcome. Research in this paradigm demonstrated the comorbid, diffuse nature of emerging psychopathology and a high degree of developmental heterotopy, suggesting the need to adopt a broader, more agnostic approach to risk identification.

Polymers (Basel) 2020 Nov 30;12(12). Epub 2020 Nov 30.

Key Laboratory of Eco-functional Polymer Materials of the Ministry of Education, Northwest Normal University, Lanzhou 730070, China.

In this study, the emergence rate, emergence potential, root length, stem length, water consumption, and biomass around a root system were used as evaluation indexes, and we used the laboratory-prepared super absorbent resin watermelon rind (WMR)-p (AA--DAAM) (superabsorbent polymer 1-SAP), WMR-p (AA--DAAM)/palygorskite (PGS) (SAP) in a laboratory and commercially available water-retaining agents (SAP and SAP) to assist the emergence of seeds and seedling growth; then, their water absorption and thermal stability were discussed. The results showed that the thermal stability of an SAP prepared in the laboratory and the water consumption during seed emergence, root length, and stem length after emergence were better than those of an SAP purchased on the market, and this information could help to promote the emergence and seedling growth of . While enhancing the drought resistance of plants, using a laboratory-produced SAP can effectively reduce the number of artificial irrigations. Read More

A comparison of penalised regression methods for informing the selection of predictive markers.

PLoS One 2020 20;15(11):e0242730. Epub 2020 Nov 20.

Faculty of Health, School of Psychology, Centre for Social and Early Emotional Development, Deakin University, Geelong, Australia.

Background: Penalised regression methods are a useful atheoretical approach for both developing predictive models and selecting key indicators within an often substantially larger pool of available indicators. In comparison to traditional methods, penalised regression models improve prediction in new data by shrinking the size of coefficients and retaining those with coefficients greater than zero. However, the performance and selection of indicators depends on the specific algorithm implemented. Read More

Compositional Fluctuations Locked by Athermal Transformation Yielding High Thermoelectric Performance in GeTe.

Adv Mater 2021 Jan 20;33(1):e2005612. Epub 2020 Nov 20.

Department of Materials Science and Engineering, National Chiao Tung University, Hsinchu, 30010, Taiwan.

Phase transition in thermoelectric (TE) material is a double-edged sword-it is undesired for device operation in applications, but the fluctuations near an electronic instability are favorable. Here, Sb doping is used to elicit a spontaneous composition fluctuation showing uphill diffusion in GeTe that is otherwise suspended by diffusionless athermal cubic-to-rhombohedral phase transition at around 700 K. The interplay between these two phase transitions yields exquisite composition fluctuations and a coexistence of cubic and rhombohedral phases in favor of exceptional figures-of-merit zT. Read More

Post-Orthodontic Lower Incisors Recessions: Combined Periodontic and Orthodontic Approach.

Int J Environ Res Public Health 2020 11 2;17(21). Epub 2020 Nov 2.

Department of Orthodontics, The Maurice and Gabriela Goldschleger School of Dental Medicine, Sackler Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel.

The bonded lingual retainer (BLR) is considered a favorable choice for retaining lower incisors' alignment post-orthodontic treatment; however, it may cause some unwanted effects such as inadvertent tooth movement and torque changes. These often result in gingival recession (Miller class III-type) with exposure of the root surface, which compromises the esthetics and hinders the comfort of the patient. Fifteen post-orthodontic patients presenting Miller class III-type recessions with BLR were examined. Read More
