Parkinson's Disease Prediction: An Attention-Based Multimodal Fusion Framework Using Handwriting and Clinical Data.

Background: Neurodegenerative diseases (NGD) encompass a range of progressive neurological conditions, such as Alzheimer's disease (AD) and Parkinson's disease (PD), characterised by the gradual deterioration of neuronal structure and function. This degeneration manifests as cognitive decline, movement impairment, and dementia. Our focus in this investigation is on PD, a neurodegenerative disorder characterized by the loss of dopamine-producing neurons in the brain, leading to motor disturbances.

The pentose phosphate pathway controls oxidative protein folding and prevents ferroptosis in chondrocytes.

Bone lengthening and fracture repair depend on the anabolic properties of chondrocytes that function in an avascular milieu. The limited supply of oxygen and nutrients calls into question how biosynthesis and redox homeostasis are guaranteed. Here we show that glucose metabolism by the pentose phosphate pathway (PPP) is essential for endochondral ossification.

Tungsten Diselenide Nanoparticles Produced via Femtosecond Ablation for SERS and Theranostics Applications.

Due to their high refractive index, record optical anisotropy and a set of excitonic transitions in visible range at a room temperature, transition metal dichalcogenides have gained much attention. Here, we adapted a femtosecond laser ablation for the synthesis of WSe nanoparticles (NPs) with diameters from 5 to 150 nm, which conserve the crystalline structure of the original bulk crystal. This method was chosen due to its inherently substrate-additive-free nature and a high output level.

The Aryl Hydrocarbon Receptor (AhR) Is a Novel Gene Involved in Proper Physiological Functions of Pancreatic β-Cells.
