INTRODUCTION: During the aging process, natural modifications occur in the larynx and the structures involved in phonation which explain the specific characteristics found in the voices of elderly persons. When, at any moment, a voice fails and there is interference with communication, a voice disorder has occurred. This can generate disadvantages in communicative efficiency and have a negative impact on quality of life, compromising mechanisms of socialization, the maintenance of autonomy, and the sense of well-being...

Globally, Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in the elderly population, the hallmark of which is amyloid β (Aβ) peptide. Energy metabolism and AD pathogenesis are believed to influence one another. Different cholesterol levels are thought to influence various steps in neurotoxic Aβ generation, including amyloid precursor protein (APP) proteolysis and the corresponding activities of α-, β-, and γ-secretases. In addition, cholesterol has been proved to mediate Aβ metabolism, such as its fibrillation, transportation, degradation, and clearance processes...

Accumulation of somatic mutations in mitochondrial DNA (mtDNA) has been proposed to be responsible for human aging and age-associated mitochondrial respiration defects. However, our previous findings suggested an alternative hypothesis of human aging-that epigenetic changes but not mutations regulate age-associated mitochondrial respiration defects, and that epigenetic downregulation of nuclear-coded genes responsible for mitochondrial translation [e.g., glycine C-acetyltransferase (GCAT), serine hydroxymethyltransferase 2 (SHMT2)] is related to age-associated respiration defects...

BACKGROUND: Plant-derived products have an imperative biological role against certain pathogenic organisms and were considered to be a major source of modern drugs. Rural people residing in developing countries are relying on traditional herbal medical system due to their strong believe and minimum access to allopathic medicines. Hence, ethnomedicinal knowledge is useful for the maintenance of community's based approaches under this medical system. Present study was carried out in an unexplored remote tribal area of Pakistan to investigate and document the existing ethnomedicinal knowledge on local flora...

Aging is associated with a significant decline of tissue repair and regeneration, ultimately resulting in tissue dysfunction, multimorbidity, and death. Salamanders possess remarkable regenerative abilities and have been studied with the prospect of inducing regeneration in humans and counteracting regenerative decline with aging. However, epimorphic regeneration, the full replacement of amputated structures, also occurs in mammals. One of the best studied models is digit tip regeneration, which is described for mice, and occurs in humans in a comparable manner...

Nutraceuticals have generated interest as a way to mitigate the cognitive decline in older adults. The aim of this systematic review was to determine the evidence for these claims from the scientific literature in randomised, double-blinded, controlled trials (duration: ≥1 year; participants: n≥100; age(mean): ≥65 years). Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched four electronic databases (PubMed, Scopus, CINAHL and Web of Science) and identified twenty-five studies published between the 15·June·2006 and 14·June·2016...

The authors seek to find new connections between recent results of biology and older theories. This paper aims to assemble the jigsaw puzzle. The theoretical background of the hypothesis was described in the previous issue of the journal (Sikter et al. 2017a). Human stress response often coexists with persistent hypocapnia or hypercapnia - developing via psychosomatic pathomechanism - which can lead to mental and psychosomatic illnesses. Chronic hypocapnia mainly generates hyperarousal disorders which may be reversible for an extended time, however, vicious cycles may start when hypoxia and/or severe somatic diseases are simultaneously present (commonly in the elderly), which conditions often end with death without medical help...

BACKGROUND: Centrifuges are the principal means of generating physiological hypergravity and have been used for many medical purposes, including the therapy of psychiatric diseases and evaluation of vestibular system in the pilots. In particular, modern centrifuges have evolved into mechanically sophisticated precision instruments compared to primitive ones in old times, indicating that centrifuges might possess great potential in modern medicine. Indeed, studies are in progress to apply centrifuges to musculoskeletal degenerative diseases, such as osteoporosis and sarcopenia...

There are now 125 million people aged 80 years and over worldwide, projected by the United Nations to grow threefold by 2050. While increases in life expectancy and rapid increases in the older-age population are considered positive developments, the consequential future health care burden represents a leading concern for health services. We revisit Williams' 'fair innings' argument from 1997, in light of technological and demographic changes, and challenge the notion that greater longevity may impose an unfair burden on younger generations...

Optical coherence tomography (OCT) manufacturers graphically present circumpapillary retinal nerve fiber layer thickness (cpRNFLT) together with normative limits to support clinicians in diagnosing ophthalmic diseases. The impact of age on cpRNFLT is typically implemented by linear models. cpRNFLT is strongly location-specific, whereas previously published norms are typically restricted to coarse sectors and based on small populations. Furthermore, OCT devices neglect impacts of lens or eye size on the diameter of the cpRNFLT scan circle so that the diameter substantially varies over different eyes...

Alzheimer's disease (AD), the most common form of dementia, is an age-related neurodegenerative disease that is characterized by memory dysfunction, neuronal cell damage, and neuroinflammation. It is believed that AD-related pathology is mostly due to the overproduction of Aβ, especially the oligomeric form (AβO), in the brain. Evidence of the effects of multifunctional medicinal herbs in the treatment of AD has been steadily increasing. Optimized-SopungSunkiwon (OSS), a multiherbal formulation that is composed of six medicinal herbs derived from SopungSunkiwon, is a traditional medicine that is prescribed for neurodegenerative disorders in elderly patients...

Interstrand cross-links (ICLs) are highly cytotoxic DNA lesions that block DNA replication and transcription by preventing strand separation. Previously, we demonstrated that the bacterial and human DNA glycosylases Nei and NEIL1 excise unhooked psoralen-derived ICLs in three-stranded DNA via hydrolysis of the glycosidic bond between the crosslinked base and deoxyribose sugar. Furthermore, NEIL3 from Xenopus laevis has been shown to cleave psoralen- and abasic site-induced ICLs in Xenopus egg extracts. Here we report that human NEIL3 cleaves psoralen-induced DNA-DNA cross-links in three-stranded and four-stranded DNA substrates to generate unhooked DNA fragments containing either an abasic site or a psoralen-thymine monoadduct...

Cesare Mancuso, Rosaria Santangelo
Recent studies have suggested the role of an infectious component in the pathogenesis of Alzheimer's disease (AD). In light of this, research has focused on some bacteria constituting the intestinal microbial flora which can produce amyloid. Once generated, the latter hypothetically triggers a systemic inflammatory response which compromises complex brain functions, such as learning and memory. Clinical studies have shown that, in cognitively impaired elderly patients with brain amyloidosis, there is lower abundance in the gut of E...

In spite of current influenza vaccines being immunogenic, evolution of the influenza virus can reduce efficacy and so influenza remains a major threat to public health. One approach to improve influenza vaccines is to include adjuvants; substances that boost the immune response. Adjuvants are particularly beneficial for influenza vaccines administered during a pandemic when a rapid response is required or for use in patients with impaired immune responses, such as infants and the elderly. This review outlines the current use of adjuvants in human influenza vaccines, including what they are, why they are used and what is known of their mechanism of action...
