[Sarcopenia as a non-motor symptom of Parkinson's disease].

Sarcopenia is a progressive generalized skeletal muscle disease that is accompanied by an accelerated loss of muscle mass and function, affecting the quality of life and the ability to perform self-care. The prevalence of sarcopenia in the world today ranges from 10 to 25%, which represents a certain danger as it is a prognostic factor for possible injury and increased disability in the elderly population. Sarcopenia often accompanies a large number of different diseases, including neurodegenerative ones, so it is actively studied in this category of patients, for example, as one of the early symptoms of Parkinson's disease (PD).

Fat embolism syndrome in Duchenne muscular dystrophy: Report on a novel case and systematic literature review.

We report a non-ambulatory 13-year-old boy with Duchenne muscular dystrophy who experienced severe acute respiratory distress syndrome and cerebral fat embolism following elective soft tissue surgery. Post-surgery radiological examination revealed bilateral femoral fractures and marked osteopenia that were believed to have caused disseminated pulmonary and cerebral fat embolism. The patient had never been on glucocorticoid treatment.

The Anatase-to-Rutile Phase Transition in Highly Oriented Nanoparticles Array of Titania with Photocatalytic Response Changes.

An array of highly oriented anatase nanoparticles was successfully prepared from NHTiOF with the assistance of polyetheleneglycol-400 at 450 °C. The study showed the stability of obtained layered TiO-anatase close to 1200 °C. This research confirmed for the first time that the transition of mesocrystalline anatase to the rutile phase occurs between 1000 °C and 1200 °C, which is more than 400 °C higher than the transition of bulk TiO due to the used precursor.

[Vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease].

Objective: To study a role of vitamin D and other indicators of calcium-phosphorus metabolism as possible predictors of Parkinson's disease (PD).

Material And Methods: The main group consisted of 138 patients with PD, the control group included 79 patients without PD. Serum levels of 25-hydroxyvitamin D (25[OH]D) were determined by chemo-luminescence immunoassay.

Association and Gene-Gene Interactions Study of Late-Onset Alzheimer's Disease in the Russian Population.

Alzheimer's disease (AD) is a neurodegenerative disorder, and represents the most common cause of dementia. In this study, we performed several different analyses to detect loci involved in development of the late onset AD in the Russian population. DNA samples from 472 unrelated subjects were genotyped for 63 SNPs using iPLEX Assay and real-time PCR.
