A novel biomimetic molecular imprinted polymer chip with fluorescence (FL) and structural (STR) states, inspired by color patterns of chameleon skin, is fabricated for detecting diethylstilbestrol (DES). The chip features a regularly structured, non-closed-packed (NCP) colloidal photonic crystal (CPC) lattice made monodisperse MIP spheres containing fluorescence poly ionic liquid (FPIL) pigments. The FL color originates from FPIL pigments and is further enhanced by the Purcell effect, while the STR color results from the periodic arrangement of the NCP CPC structure.

Model organisms are commonly used to study human diseases; we set out to understand the relevance of several model organisms with relation to the σ1R protein. The study explored the interactions of σ1R with various agonists, antagonists across different species. Ligand and protein-protein (σ1R-BiP) docking approaches were used to understand the significance of σ1R in modulating neuroprotective mechanisms and its potential role in Alzheimer's.

Osteoporosis, a condition marked by the loss of bone density and mass, affects individuals of all ages. However, it becomes more prevalent and severe with aging, increasing the risk of fractures and other health complications. Recent research has highlighted a link between osteoporosis and periodontitis, a chronic gum disease, as both conditions involve excessive bone loss that can lead to significant oral health problems if untreated.

Purpose: The primary objective of this prospective, longitudinal, observational, single-centre study was to evaluate the association between ultrasound-assessed lesions of dactylitis and the diagnosis of psoriatic arthritis (PsA) in patients with psoriasis (PsO) and hand arthralgia.
Methods: We included adult patients diagnosed with PsO with hand arthralgia, with or without other musculoskeletal complaints. They were clinically assessed at baseline, 6 and 12 months by a rheumatologist blinded to the ultrasound findings.

Triple-negative breast cancer (TNBC) is an aggressive subtype that accounts for 10-15 % of breast cancer. Current treatment of high-risk early-stage TNBC includes neoadjuvant chemo-immune therapy. However, the substantial variation in immune response prompts an urgent need for new immune-targeting agents.
