This study involved the development and testing of a system for the simultaneous in vitro measurement of tibiofemoral kinematics and patellofemoral kinematics and forces. Knee motion was tracked using a Vicon 370, and patellofemoral force was measured using a six degree-of-freedom transducer based on the design of Singerman et al. Using this system, twelve knee specimens were tested in supine leg extension under a simulated quadriceps force. The comprehensive set of results corresponds well to the individual results of previous studies. The measurement system will be of value in assessing the effects of total knee arthroplasty on patellar function.

Preterm birth (PTB) remains a leading cause of neonatal morbidity and mortality, with inflammation-induced PTB posing a significant challenge due to its complex pathophysiology. To address this, we developed an in vitro platform utilizing hTERT-immortalized human myometrial (hTERT-HM) cells integrated with a multielectrode array (MEA) biosensing system and optical calcium imaging. Compared to primary uterine myometrial cells, hTERT-HM cells exhibit superior reproducibility, high scalability, and convenient manipulation, facilitating the consistent and large-scale investigations.

FLT3 mutations occur in approximately 25% of all acute myeloid leukemia (AML) patients. While several FLT3 inhibitors have received FDA approval, their use is currently limited to combination therapies with chemotherapy, as resistance occurs, and efficacy decreases when the inhibitors are used alone. Given the highly heterogeneous nature of AML, there is an urgent need for novel targeted therapies that address the disease from multiple angles.

In recent years, deep eutectic solvents (DESs) with their outstanding solubilization properties have emerged as strong candidates for oral enabling formulations of poorly soluble drugs. This study explores the use of drug-based therapeutic DESs (THEDESs) to solubilize a poorly soluble compound with the aim of providing a fixed-dose combination of two complementary therapeutic agents. Specifically, potential anticancer effects of ibuprofen (IBU) are harnessed in a novel type of THEDES to dissolve higher amounts of abiraterone acetate (AbAc), an antitumor agent.

Significant progress has been made in the last two decades in producing small (<2μm), high-purity, and low-adsorption particles, columns and system hardware, for ultra-high pressure liquid chromatography (UHPLC). Simultaneously, the recent rapid expansion of cell and gene therapies for treating diseases necessitates novel analytical technologies for analyzing large (>2 kbp) plasmid double-stranded (ds) DNA (which encodes for the in vitro transcription (IVT) of single-stranded (ss) mRNA therapeutics) and dsRNAs (related to IVT production impurities) biopolymers. In this context, slalom chromatography (SC), a retention mode co-discovered in 1988, is being revitalized using the most advanced column technologies for improved determination of the critical quality attributes (CQAs) of such new therapeutics.

Glaucoma, a leading cause of blindness, demands innovative and effective treatments that surpass the limitations of current drug and surgical interventions to lower intraocular pressure. This study describes the generation of cell-repellent hydrogel patches, their deposition on the ocular surface, and a photoinduced chemical binding between the patches and the collagens of the eye. The hydrophilic and protein-repellent hydrogel patch is composed of a copolymer made from dimethylacrylamide and a comonomer unit with anthraquinone moieties.
