Amplification-Free Attomolar Detection of Short Nucleic Acids with Upconversion Luminescence: Eliminating Nonspecific Binding by Hybridization Complex Transfer.

The anti-Stokes emission of photon upconversion nanoparticles (UCNPs) facilitates their use as labels for ultrasensitive detection in biological samples as infrared excitation does not induce autofluorescence at visible wavelengths. The detection of extremely low-abundance analytes, however, remains challenging as it is impossible to completely avoid nonspecific binding of label conjugates. To overcome this limitation, we developed a novel hybridization complex transfer technique using UCNP labels to detect short nucleic acids directly without target amplification.

Low impact of Zostera marina meadows on sediment and water microbiota under brackish conditions.

Commentary on "Epigenome-wide analysis across the development span of pediatric acute lymphoblastic leukemia: backtracking to birth".

VTRNA2-1 is a polymorphically imprinted locus. The proportion of individuals with a maternally imprinted VTRNA2-1 locus is consistently approximately 75% in populations of European origin, with the remaining circa 25% having a non-methylated VTRNA2-1 locus. Recently, VTRNA2-1 hypermethylation at birth was suggested to be a precursor of paediatric acute lymphoblastic leukaemia with biomarker potential.

Seeking innovative concepts in development of antiviral drug combinations.

Antiviral drugs are crucial for managing viral infections, but current treatment options remain limited, particularly for emerging viruses. These drugs can be classified based on their chemical composition, including neutralizing antibodies (nAbs), recombinant human receptors (rhRs), antiviral CRISPR/Cas systems, interferons, antiviral peptides (APs), antiviral nucleic acid polymers, and small molecules. Some of these agents target viral factors, host factors, or both.

Melt electrowriting of amorphous solid dispersions: Influence of drug and plasticizer on rheology and printing performance.

Drug loaded microfiber scaffolds have potential for sublingual drug delivery due to their fast dissolution time and tunable porosity. Such microfiber scaffolds can be prepared by melt electrowriting (MEW), wherein a polymer melt is electrostatically drawn out of a syringe onto a computer controlled moving collector. The fabrication of such scaffolds via MEW has previously been shown for a polymer with a glass transition temperature (T) just above room temperature, making handling challenging.

Understanding the complexity of near-infrared quantification of highly porous patient-tailored drug products by utilizing chemometrics and stimulated Raman imaging.

Additively manufactured drug products, typically produced using small-scale, on-demand batch mode, require rapid and non-destructive quantification methods. A tunable modular design (TMD) approach combining porous polymeric freeze-dried modules and an additive manufacturing method, inkjet printing, was proposed in an earlier study to fabricate accurate and patient-tailored doses of an antidepressant citalopram hydrobromide. This approach addresses the unmet medical needs associated with antidepressant tapering.

Cationized Cellulose Materials: Enhancing Surface Adsorption Properties Towards Synthetic and Natural Dyes.

Cellulose is a homopolymer composed of β-glucose units linked by 1,4-beta linkages in a linear arrangement, providing its structure with intermolecular H-bonding networking and crystallinity. The participation of hydroxy groups in the H-bonding network results in a low-to-average nucleophilicity of cellulose, which is insufficient for executing a nucleophilic reaction. Importantly, as a polyhydroxy biopolymer, cellulose has a high proportion of hydroxy groups in secondary and primary forms, providing it with limited aqueous solubility, highly dependent on its form, size, and other materialistic properties.

Transient receptor potential vanilloid (TRPV) 4 is involved in signaling pathways specifically mediating pain and inflammation, making it a promising target for the treatment of various painful and inflammatory conditions. However, only one drug candidate targeting TRPV4 has entered the clinical trials. To identify potential TRPV4 inhibitors for drug development, we screened a library of ion channel-modulating compounds using both structure- and ligand-based virtual screening approaches.

Heptamethine Cyanine Dye-Doped Single-Walled Carbon Nanotube Electrodes for Improving Performance of HTL-Free Perovskite Solar Cells.

Perovskite solar cell (PSC) technology holds great promise with continuously improving power conversion efficiency; however, the use of metal electrodes hinders its commercialization and the development of tandem designs. Although single-walled carbon nanotubes (SWCNTs), as one-dimensional materials, have the potential to replace metal electrodes in PSCs, their poor conductivity still limits their application. In this study, the near-infrared (NIR)-absorbing anionic heptamethine cyanine dye-doped SWCNTs functioned in a dual role as an efficient charge-selective layer and electrode in PSCs.
