Bidirectional association between cognitive impairment and bone mineral density reduction in aging populations: A systematic review and meta-analysis of osteoporosis, osteopenia, and bone mineral content.

Osteoporosis is a skeletal disorder characterized by reduced bone mineral density (BMD), increasing fracture risk. Cognitive disorders (CD), including Alzheimer's disease, dementia, and mild cognitive impairment (MCI), cause cognitive decline and are prevalent among older adults. This systematic review and meta-analysis explores the bidirectional association between cognitive impairment and bone health, specifically low BMD, osteopenia, and osteoporosis.

The effect of cold plasma treatment on the phenolic and flavonoid content and antioxidant activity of whole buckwheat grain and flour.

Atmospheric cold plasma (ACP) is a novel non-thermal technology which increases shelf-life of food. The aim of this research to evaluate the effects of ACP treatment on antioxidant activity (AOA), total phenol content (TPC), total flavonoid content (TFC) and rutin and quercetin levels of Common buckwheat (Fagopyrum esculentum Moench) flour (BF) and grain (BG). Whole buckwheat grains and flour were subjected to a dielectric barrier discharge plasma reactor for 5 and 10 min at 50 and 60 kV.

Sulfonated reduced graphene oxide-doped polypyrrole film prepared by in situ electropolymerization and coating in fabrication of ammonia gas sensor for exhaled breath analysis of patients with kidney failure.

Detection of the level of ammonia gas in exhaled breath provides non-invasive and fast diagnosis of kidney failure. Here, we fabricated room temperature and sensitive chemiresistive ammonia gas sensor by in situ electropolymerization and deposition of polypyrrole/sulfonated graphene oxide (PPy/SRGO) on/between gold interdigitated electrodes (Au-IDEs). The prepared sensors were characterized by using field emission scanning electron microscopy (FESEM) and Fourier transform infrared (FT-IR).

General and central obesity prevalence in young adult: a study based on the Rafsanjan youth cohort study.

Growing prevalence of obesity among youth would have adverse consequences and increased risk of developing chronic diseases at older ages. This study explored the prevalence of obesity and its association with relevant risk factors in the Rafsanjan youth cohort population. This cross-sectional study was done on 3006 individuals from the 15-35-year-old population included in the Rafsanjan youth cohort study.

Nanoarchitected metal/ceramic interpenetrating phase composites.

Architected metals and ceramics with nanoscale cellular designs, e.g., nanolattices, are currently subject of extensive investigation.

Rheological Properties of MWCNT-Doped Titanium-Oxo-Alkoxide Gel Materials for Fiber Drawing.

A strategy of doping by multi-walled carbon nanotubes (MWCNT) to enhance mechanical strength and the electrical conductivity of ceramic fibers has nowadays attracted a great deal of attention for a wide variety of industrial applications. This study focuses on the effect of MWCNTs on rheological properties of metal alkoxide precursors used for the preparation of nanoceramic metal oxide fibers. The rheological behavior of MWCNT-loaded titanium alkoxide sol precursors has been evaluated via an extensional rheometry method.
