Influence of Klotho Protein Levels in Obesity and Sarcopenia: A Systematic Review.

The gene is recognized for its anti-aging properties. Its downregulation leads to aging-like phenotypes, whereas overexpression can extend lifespan. Klotho protein exists in three forms: α-klotho, β-klotho and γ-klotho.

Clinical characteristics associated with complications and poor visual outcomes in ocular toxoplasmosis: Analysis of 853 patients: complications and visual outcomes in ocular toxoplasmosis.

Ultrasound guided pericapsular nerve group (PENG) block resulting in reduction of dislocated prosthetic hip.

A 78-year-old woman with a prosthetic hip dislocation underwent a pericapsular nerve group block for regional anesthesia. The hip spontaneously reduced before manual intervention, likely due to the block's analgesic and muscle-relaxing effects. Compared to other techniques, this block effectively targets hip innervation while sparing motor function.

Understanding the Molecular Impact of Physical Exercise on Alzheimer's Disease.

Alzheimer's disease is one of the most common neurodegenerative diseases, characterized by a wide range of neurological symptoms that begin with personality changes and psychiatric symptoms, progress to mild cognitive impairment, and eventually lead to dementia. Physical exercise is part of the non-pharmacological treatments used in Alzheimer's disease, as it has been shown to delay the neurodegenerative process by improving the redox state in brain tissue, providing anti-inflammatory effects or stimulating the release of the brain-derived neurotrophic factor that enhances the brain structure and cognitive performance. Here, we reviewed the results obtained from studies conducted in both animal models and human subjects to comprehend how physical exercise interventions can exert changes in the molecular mechanisms underlying the pathophysiological processes in Alzheimer's disease: amyloid β-peptide pathology, tau pathology, neuroglial changes, mitochondrial dysfunction, and oxidative stress.

Two-dimensional optical binding based on graphene surface plasmon excitation.

In this work, we present a detailed analysis of the optical binding force resulting from the near field scattering between dielectric nanoparticles and a graphene substrate. We pay special attention to the two-dimensional array formation for which the stability is raised owing to the multiple surface plasmon (SP) scattering. Because of the small values of the SP wavelength on graphene in comparison with those of the photon, the size of these particle arrangements falls below the diffraction limit.
