Non-arteritic anterior ischemic optic neuropathy (NAION) is a common cause of acute optic neuropathy in the elderly. The role of the genetic polymorphisms of Atonal Homolog 7 (ATOH7), Endothelin-1 (ET-1) and Angiotensin Converting Enzyme (ACE) in NAION and the combined effects of the gene-gene and gene-medical comorbidities on NAION were not clear. We conducted a perspective, case-control study. 71 NAION patients and 142 age and sex-matched healthy controls were enrolled. Single nucleotide polymorphisms of ATOH7 (rs1900004), ET-1 (rs5370) and ACE (rs1799752) were identified by polymerase chain reaction (PCR) method and all PCR products were screened with Sanger sequencing...

Immunosenescence has been described as age-associated changes in the immune function which are thought to be responsible for the increased morbidity with age. Human Natural Killer (NK) cells are a specialized heterogeneous subpopulation of lymphocytes involved in immune defense against tumor and microbial diseases. Interestingly, aging-related NK cell dysfunction is associated with features of aging such as tumor incidence, reduced vaccination efficacy, and short survival due to infection. It is known that NK cell effector functions are critically dependent on cytokines and metabolic activity...

Ambient air pollution including ozone and especially particulate matter represents important causes of cardiovascular disease. However, there is limited knowledge on indoor air dust with respect to this risk and the potential interactions between dust and ozone. Here, we exposed 23 healthy elderly subjects for 5.5 h, to either clean air, house dust at 275 µg/m3 (diameter < 2.5 µm), ozone at 100 ppb or combined house dust and ozone in a double-blinded randomized cross-over study. The combined house dust and ozone exposure was associated with a 48% (95% CI 24%-65%) decrease as compared with the clean air exposure, in CD34+KDR+ late endothelial progenitor cells (EPCs) per leukocyte in the blood shortly after exposure, whereas none of the single exposures resulted in a significant effect...

Background: Vocimagene amiretrorepvec (Toca 511) is an investigational gamma-retroviral replicating vector encoding cytosine deaminase that, when used in combination with extended-release 5-fluorocytosine (Toca FC), results preclinically in local production of 5-fluorouracil, depletion of immune-suppressive myeloid cells, and subsequent induction of anti-tumor immunity. Recurrent high grade glioma (rHGG) patients have a high unmet need for effective therapies that produce durable responses lasting more than 6 months...

Endothelial progenitor cells (EPCs) contribute to the endogenous endothelial repair program during hypercholesterolemia. EPC count and migratory and proliferative capacities remain unchanged in the premenopausal female with hypercholesterolemia. However, the changes of count and activity of circulating EPCs in the hypercholesterolemic postmenopausal females are unknown. Here, we find that the migratory and proliferative capacities of circulating EPCs were decreased in patients with hypercholesterolemia versus normocholesterolemia...

Rural areas in Indonesia are older relative to urban areas. This paper questions how levels of social engagement vary across among the elderly in rural Indonesia. A sample of 2750 respondents aged 60 and over was drawn from 10 purposely-selected relatively "old" villages. Our three measures of social engagement are: participation in income-generating activities, in communal activities, and in care work. While there are notable village-level differences in patterns of social engagement, the majority of our respondents are actively engaged in productive activities in their old age until they can no longer be so...

Gut microbiota can influence the aging process and may modulate aging-related changes in cognitive function. Trimethylamine-N-oxide (TMAO), a metabolite of intestinal flora, has been shown to be closely associated with cardiovascular disease and other diseases. However, the relationship between TMAO and aging, especially brain aging, has not been fully elucidated. To explore the relationship between TMAO and brain aging, we analysed the plasma levels of TMAO in both humans and mice and administered exogenous TMAO to 24-week-old senescence-accelerated prone mouse strain 8 (SAMP8) and age-matched senescence-accelerated mouse resistant 1 (SAMR1) mice for 16 weeks...

The pathological phenomenon of somatopause, noticeable in hypogonadal ageing subjects, is based on the growth hormone (GH) production and secretion decrease along with the fall in GH binding protein and insulin-like growth factor 1 (IGF-1) levels, causing different musculoskeletal, metabolic and mental issues. From the perspective of safety and efficacy, GH treatment is considered to be highly controversial, while some other therapeutic approaches (application of IGF-1, GH secretagogues, gonadal steroids, cholinesterase-inhibitors or various combinations) exhibit more or less pronounced weaknesses in this respect...

Feline immunodeficiency virus (FIV) is the feline analogue to human immunodeficiency virus (HIV) and utilizes parallel modes of receptor-mediated entry. The FIV surface glycoprotein (SU) is an important target for induction of neutralizing antibodies, and autoantibodies to the FIV binding receptor (CD134) block infection ex vivo; thus highlighting the potential for immunotherapies which utilize anti-receptor antibodies to block viral infection. To determine whether vaccination with CD134-SU complexes could induce protection against FIV infection, cats ( n  = 5 per group) were immunized with soluble CD134, recombinant FIV-SU protein, and/or CD134+SU complexes...

There is a rapid increase in the percentage of elderly people in Europe. Consequently, the prevalence of age-related diseases will also significantly increase. Therefore, the main goal of MediHealth, an international research project, is to introduce a novel approach for the discovery of active agents of food plants from the Mediterranean diet and other global sources that promote healthy ageing. To achieve this goal, a series of plants from the Mediterranean diet and food plants from other origins are carefully selected and subjected to in silico, cell-based, in vivo (fly and mouse models), and metabolism analyses...

Prebiotic oligosaccharides are known to have significant impacts on gut microbiota and are thus widely used to program healthy microbiota composition and activity from infants to the elderly. Bifidobacteria and lactobacilli are among the major target microorganisms of oligosaccharides, but the metabolic properties of oligosaccharides in other predominant gut microbes have not been well characterized. In the present study, we demonstrated the metabolic properties of six oligosaccharides in 31 key gut anaerobes...

BACKGROUND: Interleukin-6 (IL-6) production facilitates a shift from acute to chronic inflammation that may induce the development of some diseases and aging. Several studies have suggested that adiposity is closely related to serum IL-6 level, but their authors examined relatively young older adults (aged 60-80 years), so it is not clear whether this association would also occur in people at a more advanced age. OBJECTIVE: to assess whether in elderly women without inflammation the widely used anthropometric obesity indices are associated with serum IL-6 level and, if so, to determine the best anthropometric predictor of this inflammatory biomarker...

Klebsiella pneumoniae (K. pneumoniae), as an important hospital-acquired bacterium, is responsible for severe morbidity and mortality among the elderly, newborn and immune-compromised people. We established a rcsA gene-based label-free multiple cross displacement amplification (MCDA) assay for rapid, simple and sensitive detection of K. pneumoniae by using lateral flow biosensor (LFB). MCDA reaction was conducted at a fixed temperature (65 °C) for only 30 min, and amplification results were directly indicated using LFB...

Immune-aging is associated with perturbed immune responses in the elderly. CD161-expressing T cells, i.e., the previously described subsets of CD161+ CD4+ T cells, CD161high CD8+ T cells, and CD161int CD8+ T cells, are highly functional, pro-inflammatory T cells. These CD161-expressing T cells are critical in immunity against microbes, while possibly contributing to autoimmune diseases. So far, little is known about the impact of aging on the frequency, phenotype, and function of these CD161-expressing T cells...

In industrialized countries, age-related macular degeneration (AMD) is the leading cause of blindness in elderly people. Hallmarks of the non-neovascular (dry) form of AMD are the formation of drusen and geographic atrophy, whereas the exudative (wet) form of the disease is characterized by invading blood vessels. In retinal angiomatous proliferation (RAP), a special form of wet AMD, intraretinal vessels grow from the deep plexus into the subretinal space. Little is known about the mechanisms leading to intraretinal neovascularization, but age-related changes such as reduction of choroidal blood flow, accumulation of drusen, and thickening of the Bruch's membrane may lead to reduced oxygen availability in photoreceptors...

C-reactive protein (CRP) is an acute inflammatory protein that increases up to 1,000-fold at sites of infection or inflammation. CRP is produced as a homopentameric protein, termed native CRP (nCRP), which can irreversibly dissociate at sites of inflammation and infection into five separate monomers, termed monomeric CRP (mCRP). CRP is synthesized primarily in liver hepatocytes but also by smooth muscle cells, macrophages, endothelial cells, lymphocytes, and adipocytes. Evidence suggests that estrogen in the form of hormone replacement therapy influences CRP levels in the elderly...
