As the burden of Alzheimer's disease (AD) escalates with an ageing population, the demand for early and accessible diagnostic methods becomes increasingly urgent. Saliva, with its non-invasive and cost-effective nature, presents a promising alternative to cerebrospinal fluid and plasma for biomarker discovery. : In this study, we conducted a comprehensive multi-omics analysis of saliva samples ( = 20 mild cognitive impairment (MCI), = 20 Alzheimer's disease and age- and = 40 gender-matched cognitively normal individuals), from the South Australian Neurodegenerative Disease (SAND) cohort, integrating proteomics, metabolomics, and microbiome data with plasma measurements, including pTau181.

The majority of smokers know the health risks associated with smoking and intend to quit. However, quitting is very difficult partly because of insomnia and stress associated with it.

Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects.

Methods: 14 consecutive patients underwent spectral imaging and MRI spinal imaging, from January 2023 to March 2024 were retrospectively analyzed. 85 vertebrae were assessed for the detection of fracture on conventional CT images and the presence of bone marrow edema (BME) in all vertebral bodies on VNCa mapping for both Bone and Research preset, who was judged to indicate a fresh fracture.
