When nanoparticle delivery systems are immersed in biological fluids, a complex assembly of proteins forms on their surface, creating a protein corona. The protein corona alters the physicochemical properties, toxicity, biodistribution, cellular uptake, and immune response of the nanoparticles, and consequently, their therapeutic efficacy. Currently, there is a lack of methods to assess the effects of the protein corona on nanoparticle uptake under dynamic flow and assess their binding kinetics in real-time.
View Article and Find Full Text PDFLipid nanoparticles (LNPs) are biocompatible drug delivery systems that have found numerous applications in medicine. Their versatile nature enables the encapsulation and targeting of various types of medically relevant molecular cargo, including oligonucleotides, proteins, and small molecules for the treatment of diseases, such as cancer. Cancers that form solid tumors are particularly relevant for LNP-based therapeutics due to the enhanced permeation and retention effect that allows nanoparticles to accumulate within the tumor tissue.

Our aim was to evaluate the quality of life in a Romanian sample of individuals with subjective cognitive decline compared to controls while accounting for different possible moderators. To our knowledge, this is the first study to evaluate the quality of life in a Romanian subjective cognitive decline sample.

Physical barriers become more pronounced in pathological tissues, such as solid tumors, where they limit the penetration of nanocarriers into deeper regions, thereby preventing the efficient delivery of drug cargo. To address this challenge, we introduce a novel approach that employs surface acoustic wave (SAW) technology to sonoprint and enhance the delivery of nanoparticles onto and into cell spheroids.

Our objective was to assess the cognitive function of three groups: one with SCD who claimed to be worried about their symptoms, one with SCD who did not claim to be worried about their symptoms and one without SCD (control group). We designed a cross-sectional study including people from primary care units and a memory center.

By its current definition, subjective cognitive decline conceptually implies that the sufferer presents no psychometrically measurable cognitive impairment despite numerous articles stating the presence of discrete objective impairments. Our purpose was to evaluate differences in objective cognitive performance in subjective cognitive decline patients compared to healthy controls.

Design: This is a three-wave cohort study. Risk factors were measured at baseline (2010-2012) and at follow-up 1 (FU1; 2012-2014), while the consequences and TBI were measured at follow-up 2 (FU2; 2016-2018).
Cystic fibrosis (CF) is the most common autosomal recessive genetic disease in Caucasians, affecting more than 100,000 individuals worldwide. It is caused by pathogenic variants in the gene encoding , an anion channel at the plasma membrane of epithelial and other cells. Many CF pathogenic variants disrupt the biosynthesis and trafficking of CFTR or reduce its ion channel function.

However, no clinical formulation of CuET exists to date as the drug is insoluble in water and exhibits poor bioavailability. To develop a scalable formulation, nanoliposomal (LP) CuET was synthesized using ethanol injection as a facile one-step method that is suitable for large-scale manufacturing.

Cannabidiol (CBD) has been used as a pharmacological treatment for psychiatric disorders in many studies, but few of good quality at the moment. Our objective was to assess the effect of CBD in mono/add-on therapy on symptom severity in psychiatric disorders. We performed a systematic review of clinical trials and randomized controlled trials that used CBD as treatment for psychiatric disorders.
