Age-Related Changes in Serum -Glycome in Men and Women-Clusters Associated with Comorbidity.

(1) Aim: To describe, in a general adult population, the serum glycome in relation to age in men and women, and investigate the association of glycome patterns with age-related comorbidity; (2) Methods: The serum glycome was studied by hydrophilic interaction chromatography with ultra-performance liquid chromatography in 1516 randomly selected adults (55.3% women; age range 18-91 years). Covariates included lifestyle factors, metabolic disorders, inflammatory markers, and an index of comorbidity.

Dementia and Challenging Behaviors in Gerontological Centers. A Case Report.

Among the main challenges in geriatric and gerontological centers, we consider, central, the individualized attention to those elderly persons with challenging behaviors, to the extent that it is possible to design preventive strategies that delay cognitive deterioration and minimize consequences of behavior disorders. The first step will be to develop the correct interpretation of symptoms and deficits as a guarantee of a correct diagnosis which, in addition to not always being easy, has to be adapted to the progression of the disease. We present the case of a 68-year-old institutionalized individual, with an initial diagnosis of diffuse Lewy bodies dementia, analyzing his cognitive and behavioral evolution, and the pharmacological and non-pharmacological approach to the case.

Luteolin as an anti-inflammatory and neuroprotective agent: A brief review.

According to the World Health Organization, two billion people will be aged 60 years or older by 2050. Aging is a major risk factor for a number of neurodegenerative disorders. These age-related disorders currently represent one of the most important and challenging health problems worldwide.

Transport of PLA-PEG particles across the nasal mucosa: effect of particle size and PEG coating density.

The aim of the study was to investigate the effect of the size and PEG coating density of Poly(lactic acid)-poly(ethylene glycol) (PLA-PEG) nano- and microparticles on their transport across the nasal mucosa. Particles were made of PLA-PEG copolymers of two different molecular weights (Mw: 37 and 28 kDa) and also PLA of Mw 28 kDa, and prepared using different techniques (simple emulsion (o/w), double emulsion (w/o/w), and nanoprecipitation techniques). The particles were characterized for their size, zeta potential, morphology [Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM)], and PEG coating efficiency.
