Abstract:
This study is to investigate the effect of PAM on protein adsorption and osteoblastic cells adhesion to HA bioceramics. PAM was immobilized on the surface of HA bioceramics for bone scaffold by chelating. The outermost layer of the specimens was analyzed by XPS and FT-IR. The protein adsorption test was performed using the 10% bovine calf serum absorbed on the specimens in vitro. The osteoblastic cells were inoculated and cultured on the scaffolds. SEM, MTT test and ALP activity test evaluated the cell attachment, proliferation and activity on the scaffolds. Characteristic peaks in XPS and FT-

Abstract:
Lithium metal is the most promising candidate for a high-capacity anode in Li-ion batteries due to the highest theoretical specific capacity (3,860 mAh g-1) and the lowest redox potential (-3.04 V vs S.H.E.) [1]. However, the Li metal anode (LMA) is still challenging to be used practically due to mossy-like dendrite formation, dead Li growth, and infinite volume expansion resulting in safety hazards. Various approaches have been proposed to suppress Li dendrite growth, such as constructing an artificial solid electrolyte layer (ASEI) [2], modifying organic electrolyte [3], preparing lithiophil

Abstract:
Introduction: Next generation sequencing techniques have identified a large number of MDS associated acquired molecular lesions. However, translation of these possible molecular targets into new therapeutic strategies has been lagging behind. This is also due to a lack of functional experimental models of MDS, in which new hypotheses can be evaluated pre-clinically. Xenograft models in NSG mice have emerged as versatile preclinical platforms for investigation of functional pathomechanisms in MDS ([1] Medyouf et al., 2014, [2] Rouault-Pierre et al., 2017). The limiting factor of these models is

Abstract We present Augustus, a catalog of distance, extinction, and stellar parameter estimates for 170 million stars from 14 mag < r < 20 mag and with ∣b∣ > 10° drawing on a combination of optical to near-infrared photometry from Pan-STARRS, 2MASS, UKIDSS, and unWISE along with parallax measurements from Gaia DR2 and 3D dust extinction maps. After applying quality cuts, we find 125 million objects have “high-quality” posteriors with statistical distance uncertainties of ≲10% for objects with well-constrained stellar types. This is a substantial improvement over the distance estimate

Abstract:
The need for clean energy solutions in order to significantly lower our carbon footprint is placing increasing attention on renewable energy, such as wind and solar. However, these technologies suffer from intermittency issues, thus making efficient energy storage and conversion a major requirement. One of the solutions to this problem is electrochemical CO2 reduction (CO2RR), using renewable energy to produce green fuels and chemicals. However, the reduction of CO2 is thermodynamically and kinetically unfavorable. To overcome this, the development of highly efficient and selective electrocata

Abstract:
Semi-artificial photosynthesis interfaces biological catalysts with synthetic materials such as electrodes or light absorbers to overcome limitations in natural and artificial photosynthesis. The benefit of using biocatalysts in electrocatalytic CO2 reduction is their electrochemical reversibility that enables their operation at very low overpotentials with high selectivity. This presentation will summarise my research group’s progress in integrating the CO2 reducing enzyme formate dehydrogenase into bespoke hierarchical 3D electrode scaffolds and the exploitation in solar-powered catalysis.

Abstract An in vitro model of intestine epithelium with an immune compartment was bioengineered to mimic immunologic responses seen in inflammatory bowel disease [1]. While aspects of intestinal immunity can be modeled in transwells and 2D culture systems, 3D tissue models improve physiological relevance by providing a 3D substrate which enable migration of macrophages towards the epithelium. An intestinal epithelium comprised of non-transformed human colon organoid cells and a subepithelial layer laden with monocyte-derived macrophages was bioengineered to mimic native intestinal mucosa cell

Overall response rates (ORRs) to MRCLS treatment are low (1L, <20%; 2L, <10%) [2]. Lete-cel, an autologous T-cell therapy, targets NY-ESO-1/LAGE-1a+ tumors using a genetically modified, high-affinity T-cell receptor. High-dose lymphodepletion (LD) was linked with better responses in synovial sarcoma [3]; the current study tested this hypothesis in MRCLS.
