A new complex multiple forklike ZnO nanostructure was fabricated by citric acid assisted annealing process. The complex multiple forklike ZnO nanostructure is composed of several nanorods. These nanorods grow from a thin platelet base and are parallel to each other to form complex multiple forklike ZnO nanostructure. The widthes of thin platelet bases range from 60 to 230 nm. The diameters of the nanorods range from 16 to 60 nm, and their lengths are 0.5 mu approximately 1.3mu. FT-IR spectrum, room-temperature PL, and UV-Vis absorption spectra are also discussed. A possible growth mechanism is proposed. Complex multiple forklike ZnO nanostructure was first used to construct a novel enzymatic biosensor based on the ZnO/CHIT inorganic-organic composite film. Well-studied horseradish peroxidase (HRP) was chosen as a model enzyme. The as-prepared biosensor displays ultrahigh sensitivity, quick response time, low detection limit and small apparent Michaelis-Menten constant. These results show that the Complex multiple forklike ZnO nanostructure is a promising material to construct enzyme biosensors.

Chlorinated hydrocarbons are widely used as solvents and synthetic intermediates, but their chemical persistence can cause hazardous environmental accumulation. Haloalkane dehalogenase from (DhlA) is a bacterial enzyme that naturally converts toxic chloroalkanes into less harmful alcohols. Using a multiscale approach based on the empirical valence bond method, we investigate the catalytic mechanism of 1,2-dichloroethane dehalogenation within DhlA and its mutants.

Type 1 diabetes mellitus (T1DM) and systemic lupus erythematosus (SLE) are both autoimmune diseases influenced by multiple genetic and environmental factors, but rarely coexist. This case describes a 13-year-old girl with early onset of T1DM who was diagnosed with SLE 12 years later, highlighting diagnostic and therapeutic challenges, particularly in distinguishing kidney involvement and management without exacerbating hyperglycemia. The patient presented with edema of the eyelids and lower limbs.

Coordination polymers (CPs) are versatile materials formed by metal ions and organic ligands, offering a broad range of structural and functional possibilities. Phosphonates and phosphinates are particularly attractive ligands for CPs due to their multiple binding sites, varied coordination geometries, and ability to form robust network structures. Phosphonates, considered harder ligands, form strong bonds with hard metals such as Fe, while phosphinates offer additional versatility due to the varied pendant groups on phosphorus.

Objective: Acetabular fractures are among the most severe injuries in trauma surgery. In younger patients, they typically result from high-energy trauma and are often associated with polytrauma. Treatment complexity and rehabilitation outcomes are influenced by overall injury severity.

Purpose: Michigan Screening and Intervention for Glaucoma and Eye Health through Telemedicine Program (MI-SIGHT) was developed to facilitate access to glaucoma and eye disease screening and improve attendance at recommended follow-up in underserved communities. MI-SIGHT offered free eye disease screenings, low-cost glasses and for those who screened positive for glaucoma, personalized education, and language-concordant coaching grounded in motivational interviewing. The primary aims of this study were 1) To explore barriers to eye care among Latine participants with limited English proficiency (LEP) who screened positive for glaucoma, 2) to understand whether and how the MI-SIGHT program facilitated access to care and 3) to understand participant experience in MI-SIGHT to inform the development of future interventions.
