Improvement of Redox State and Functions of Immune Cells as Well as of Behavioral Response in Aged Mice After Two-Week Supplementation of Fermented Milk with Probiotics.

The homeostatic systems, such as the nervous and immune systems, show deterioration in aging as a consequence of the age-related oxidative-inflammatory stress establishment. The supplementation with fermented milk containing probiotic bacteria could be a good nutritional strategy to improve homeostatic system functions in aged individuals through the modulation of their redox state. The aim of the present study was to evaluate the effect of 2-week supplementation with a commercial fermented milk containing yogurt species (Lactobacillus delbrueckii subsp.

Cerebral versus Ocular Visual Impairment: The Impact on Developmental Neuroplasticity.

Cortical/cerebral visual impairment (CVI) is clinically defined as significant visual dysfunction caused by injury to visual pathways and structures occurring during early perinatal development. Depending on the location and extent of damage, children with CVI often present with a myriad of visual deficits including decreased visual acuity and impaired visual field function. Most striking, however, are impairments in visual processing and attention which have a significant impact on learning, development, and independence.

Mitochondrial DNA haplogroups influence the risk of incident knee osteoarthritis in OAI and CHECK cohorts. A meta-analysis and functional study.

Objective: To evaluate the influence of the mitochondrial DNA (mtDNA) haplogroups in the risk of incident knee osteoarthritis (OA) and to explain the functional consequences of this association to identify potential diagnostic biomarkers and therapeutic targets.

Methods: Two prospective cohorts contributed participants. The osteoarthritis initiative (OAI) included 2579 subjects of the incidence subcohort, and the cohort hip and cohort knee (CHECK) included 635, both with 8-year follow-up.

Common Genetic Polymorphisms within NFκB-Related Genes and the Risk of Developing Invasive Aspergillosis.

Invasive Aspergillosis (IA) is an opportunistic infection caused by Aspergillus, a ubiquitously present airborne pathogenic mold. A growing number of studies suggest a major host genetic component in disease susceptibility. Here, we evaluated whether 14 single-nucleotide polymorphisms within NFκB1, NFκB2, RelA, RelB, Rel, and IRF4 genes influence the risk of IA in a population of 834 high-risk patients (157 IA and 677 non-IA) recruited through a collaborative effort involving the aspBIOmics consortium and four European clinical institutions.

Retinal nerve fiber layer and macular thickness in patients with schizophrenia: Influence of recent illness episodes.

Optical coherence tomography (OCT) has been recently used to investigate neuropsychiatric disorders. We aimed to study retinal OCT measures of patients with schizophrenia with respect to healthy controls, and to evaluate possible differences between recent illness episode (RIE) and non-recent illness episode (NRIE) patients. Thirty schizophrenia patients were classified as RIE (n=10) or NRIE (n=20), and compared with 30 matched controls.

Smart Mesoporous Silica Nanocarriers for Antitumoral Therapy.

The development of nanocarriers able transport and release therapeutic agents in a controlled manner has provided a promising alternative in the oncology field due to the lack of selectivity of the conventional treatments. The encapsulation of cytotoxic compounds within nanoparticles improves the pharmacokinetic profile of the trapped drugs and allows their selective accumulation into the tumoral tissue owing to the enhance permeation and retention effect (EPR. In addition, the selectivity of the nanocarrier can be enhanced attaching targeting agents on their surface able to be specifically recognized by cancer cells or by the tumor microenvironment.

Reduced visual surround suppression in schizophrenia shown by measuring contrast detection thresholds.

Visual perception in schizophrenia is attracting a broad interest given the deep knowledge that we have about the visual system in healthy populations. One example is the class of effects known collectively as visual surround suppression. For example, the visibility of a grating located in the visual periphery is impaired by the presence of a surrounding grating of the same spatial frequency and orientation.

The pathogenicity scoring system for mitochondrial tRNA mutations revisited.

Confirming the pathogenicity of mitochondrial tRNA point mutations is one of the classical challenges in the field of mitochondrial medicine. In addition to genetic and functional studies, the evaluation of a genetic change using a pathogenicity scoring system is extremely useful to discriminate between disease-causing mutations from neutral polymorphisms. The pathogenicity scoring system is very robust for confirming pathogenicity, especially of mutations that show impaired activity in functional studies.

Pathological alteration in the choroid plexus of Alzheimer's disease: implication for new therapy approaches.

Morphological alterations of choroid plexus in Alzheimer's disease (AD) have been extensively investigated. These changes include epithelial atrophy, thickening of the basement membrane, and stroma fibrosis. As a result, synthesis, secretory, and transportation functions are significantly altered resulting in decreased cerebrospinal fluid (CSF) turnover.
