holds significant therapeutic potential; however, its nonspecific invasiveness results in off-target effects. The purpose of this study is to evaluate whether specificity can be improved by surface display of scFv directed against dendritic cells' endocytic receptor, DEC205, and immune checkpoint PD-L1. Anti-DEC205 scFv was anchored to the surface either directly via glycosylphosphatidylinositol (GPI) or by fusion with the SAG1 protein.

Evaluating Nanoparticles Penetration by a New Microfluidic Hydrogel-Based Approach.

Reliable predictions for the route and accumulation of nanotherapeutics in vivo are limited by the huge gap between the 2D in vitro assays used for drug screening and the 3D physiological in vivo environment. While developing a standard 3D in vitro model for screening nanotherapeutics remains challenging, multi-cellular tumor spheroids (MCTS) are a promising in vitro model for such screening. Here, we present a straightforward and flexible 3D-model microsystem made out of agarose-based micro-wells, which enables the formation of hundreds of reproducible spheroids in a single pipetting.

Here, we investigated the potential antiviral properties of plants adapted to high-salt environments collected in the north of France. Twenty-five crude methanolic extracts obtained from twenty-two plant species were evaluated for their cytotoxicity and antiviral effectiveness against coronaviruses HCoV-229E and SARS-CoV-2.

Why personalized surgery is the future of hip and knee arthroplasty: a statement from the Personalized Arthroplasty Society.

Although hip and knee joint replacements provide excellent clinical results, many patients still do not report the sensation and function of a natural joint. The perception that the joint is artificial may result from the anatomical modifications imposed by the surgical technique and the implant design. Moreover, the joint replacement material may not function similarly to human tissues.

Which method for femoral component sizing when performing kinematic alignment TKA? An in silico study.

Introduction: The kinematically alignment (KA) technique for TKA aims to reproduce the pre-arthritic knee anatomy, including both the femoro-tibial and femoro-patellar joints. An in silico study was conducted to compare 3 different femoral component sizing techniques to identify the anatomical landmark which allows closest restoration of the native trochlear anatomy. Our study's question was: what was the best method for sizing the femoral component when performing KA-TKA? It was hypothesized that sizing the femoral component by aiming to restore the groove height would be the best method to restore the native trochlear anatomy.

Phytochemical characterisation and aromatic potential for brewing of wild hops (Humulus lupulus L.) from Northern France: Towards a lead for local hop varieties.

In the current context of developing aromatic beers, our study aims at deciphering the chemical characterisation of cones from 39 wild hop genotypes collected in the North of France and replanted in an experimental hop farm, as well as 10 commercial and 3 heirloom varieties, using HS-SPME/GC-MS for the volatile compounds, UHPLC-UV for phenolic compound quantification, and UHPLC-IMS-HRMS for untargeted metabolomics. These analyses revealed a strong opposition between wild accessions and reference varieties, and an original chemical composition of some genotypes. 27 beers were produced with the same recipe, analysed by SBSE-GC-MS and evaluated by panellists.

Antifungal Activity of Hop Leaf Extracts and Xanthohumol on Two Strains of with Different Sensitivities to Triazoles.

Hop cones are well-known for their antimicrobial properties, attributed to their specialized metabolites. Thus, this study aimed to determine the in vitro antifungal activity of different hop parts, including by-products such as leaves and stems, and some metabolites against , the causal agent of apple scab. For each plant part, two types of extracts, a crude hydro-ethanolic extract and a dichloromethane sub-extract, were tested on spore germination of two strains with different sensitivities to triazole fungicides.

Luteolin Isolated from L., a Potential Remedy for Human Coronavirus 229E.

The COVID-19 pandemic, caused by SARS-CoV-2, addressed the lack of specific antiviral drugs against coronaviruses. In this study, bioguided fractionation performed on both ethyl acetate and aqueous sub-extracts of stems led to identifying luteolin as a highly active antiviral molecule against human coronavirus HCoV-229E. The apolar sub-extract (CHCl) containing phenanthrene derivatives did not show antiviral activity against this coronavirus.

Same-day testing with initiation of antiretroviral therapy or tuberculosis treatment versus standard care for persons presenting with tuberculosis symptoms at HIV diagnosis: A randomized open-label trial from Haiti.

Background: Same-day HIV testing and antiretroviral therapy (ART) initiation is being widely implemented. However, the optimal timing of ART among patients with tuberculosis (TB) symptoms is unknown. We hypothesized that same-day treatment (TB treatment for those diagnosed with TB; ART for those not diagnosed with TB) would be superior to standard care in this population.

Background: Metastases are the leading cause of mortality in many cancer types and lungs are one of the most common sites of metastasis alongside the liver, brain, and bones. In melanoma, 85% of late-stage patients harbor lung metastases. A local administration could enhance the targeting of metastases while limiting the systemic cytotoxicity.

Evolution of Concepts: Can Personalized Hip Arthroplasty Improve Joint Stability?

Hip arthroplasty procedures are successful and reproducible. However, within the first two post-operative years, hip dislocations are the most common cause for revisions. This is despite the majority of the dislocations having the acetabular component within what is described as the 'safe zone'.

Cable Tension Optimization for an Epicardial Parallel Wire Robot.

HeartPrinter is a novel under-constrained 3-cable parallel wire robot designed for minimally invasive epicardial interventions. The robot adheres to the beating heart using vacuum suction at its anchor points, with a central injector head that operates within the triangular workspace formed by the anchors, and is actuated by cables for multipoint direct gene therapy injections. Minimizing cable tensions can reduce forces on the heart at the anchor points while supporting rapid delivery of accurate injections and minimizing procedure time, risk of damage to the robot, and strain to the heart.
