وَٱللَّهُ خَلَقَكُمۡ ثُمَّ يَتَوَفَّىٰكُمۡۚ وَمِنكُم مَّن يُرَدُّ إِلَىٰٓ أَرۡذَلِ ٱلۡعُمُرِ لِكَيۡ لَا يَعۡلَمَ بَعۡدَ عِلۡمࣲ شَيۡـًٔاۚ إِنَّ ٱللَّهَ عَلِيمࣱ قَدِيرࣱ
It is God who has created you and in time will cause you to die. Some of you will be reduced, in old age, to a most abject state, so that, after having knowledge, they will know nothing at all: God is truly all knowing and all powerful

People, [remember,] if you doubt the Resurrection, that We created you from dust, then a drop of fluid, then a clinging form, then a lump of flesh, both shaped and unshaped: We mean to make Our power clear to you. Whatever We choose We cause to remain in the womb for an appointed time, then We bring you forth as infants and then you grow and reach maturity. Some die young and some are left to live on to such an age that they forget all they once knew. You sometimes see the earth lifeless, yet when We send down water it stirs and swells and produces every kind of joyous growth

Praise be to God, who has granted me Ishmael and Isaac in my old age: my Lord hears all requests
قَالَ أَبَشَّرۡتُمُونِي عَلَىٰٓ أَن مَّسَّنِيَ ٱلۡكِبَرُ فَبِمَ تُبَشِّرُونَ
He said, ‘How can you give me such news when old age has come to me? What sort of news is this?’

Would any of you like to have a garden of palm trees and vines, graced with flowing streams and all kinds of produce, which, when you are afflicted with old age and feeble offspring, is struck by a fiery whirlwind and burnt down? In this way God makes His messages clear to you, so that you may reflect on them
Commentary on the verses above, at most two editions per verse.
And God has created you when you were nothing then He takes you in death when your terms of life are concluded; and there are some among you who are relegated to the most abject stage of life that is the most diminished because of old-age and senility so that he knows nothing after having possessed some knowledge. ‘Ikrima said ‘Whoever recites the Qur’ān will not come to such a predicament’. God is Knowing of how to manage the affairs of His creation Powerful in doing what He will.
And Allah created you and then He will cause you to die; and among you there are some who are sent back to senility, so that they know nothing after having known (much). Truly, Allah is Knowing, capable of all things (70) In Man there is a Lesson Allah tells us that He is controlling the affairs of His servants. He is the One Who created them out of nothing, then He will cause them to die. But there are some of them that He allows to grow old, which is a physical weakness, as Allah says: اللَّهُ الَّذِي خَلَقَكُم مِّن ضَعْفٍ ثُمَّ جَعَلَ مِن بَعْدِ ضَعْفٍ قُوَّةً (Allah is He Who created you in (a state of) weakness, then gave you strength after weakness, then after strength gave (you) weakness)(30:54) لِكَيْ لَا يَعْلَمَ بَعْدَ عِلْمٍ شَيْئًا (so that they know nothing after having known.) meaning, after he knew things, he will reach a stage where he knows nothing because of weakn
O people, if you are in doubt about the Uprising, surely We created you of dust, then of a sperm drop, then of a blood clot, then of a lump of flesh, fully created and not fully created, that We might make clear to you. The composition of the Adamic body in the first creation is a clear argument against the deniers of the Uprising. He is saying, “I am the Lord who created a body and figure with such comeliness, a stature and form with such beauty, from that feeble sperm drop in that firm settledness. He says, “Did We not create you of feeble water, then put it in a firm settledness?” [77:20-21]. If you ponder this body, you will find an exemplar of all the created and newly arrived things in the celestial and terrestrial worlds. Just as He arranged the seven spheres in heaven, so also He composed seven parts in this body-water and dust, and then flesh, skin, veins, sinews, and bones. Jus
God is the One Who created you from a state of weakness from a ‘base fluid’ cf. Q. 328 then He ordained after a second weakness which is the weakness of the period of childhood strength that is the strength of youth then after strength He appointed weakness again and grey hair the weakness of old age and the grey hairs of decrepitude read vocalised as du‘f ‘weakness’ in all three places. He creates what He will of weakness and strength youth and grey hairs and He is the Knower of how to manage His creatures the Omnipotent.
Allah is He Who created you in weakness, then gave you strength after weakness, then after strength gave (you) weakness and grey hair. He creates what He wills. And He is the All-Knowing, the All-Powerful (54) The Different Stages of Man Here Allah points out how man passes through different stages of creation, one phase after another. He is originally created from dust, then from a Nutfah, then from a clot, then from a lump of flesh. Then he becomes bones, then the bones are clothed with flesh, then the soul is breathed into him. Then he emerges from his mother's womb, weak and thin and powerless. Then he grows up little by little, until he becomes a child, then he reaches the stage of puberty, then he becomes a young man, which is strength after weakness. Then he starts to get older, reaching middle age, then old age and senility, weakness after strength, so he loses his resolve, pow

Lifestyle Modulators of Neuroplasticity: How Physical Activity, Mental Engagement, and Diet Promote Cognitive Health during Aging.
The number of the elderly across the globe will approximate 2.1 billion by 2050. Juxtaposed against this burgeoning segment of the population is evidence that nonpathological aging is associated with an increased risk for cognitive decline in a variety of domains, changes that can cause mild disability even before the onset of dementia. Given that pharmacological treatments that mitigate dementia are still outstanding, alternative therapeutic options are being investigated increasingly. The results from translational studies have shown that modifiable lifestyle factors-including physical activity, cognitive engagement, and diet-are a key strategy for maintaining brain health during aging. Indeed, a multiplicity of studies has demonstrated relationships between lifestyle factors, brain structure and function, and cognitive function in aging adults. For example, physical activity and diet …

Weight Gain in Women at Midlife: A Concise Review of the Pathophysiology and Strategies for Management.
Weight gain accompanied by an increased tendency for central fat distribution is common among women in midlife. These changes are a result of aging, decreasing estrogen levels after menopause, and other unique influences in menopausal women that interfere with the adoption of healthy lifestyle measures. Central obesity, in particular, results in several adverse metabolic consequences, including dysglycemia, dyslipidemia, hypertension, and cardiovascular disease. Given that cardiovascular disease is the leading cause of death in postmenopausal women, the importance of weight management in midlife cannot be overemphasized. In addition, weight gain in midlife contributes to other health risks including cancer, arthritis, mood disorders, and sexual dysfunction. It is imperative that primary care physicians screen midlife women for overweight/obesity and offer appropriate advice and referral.…

Telomere shortening during aging: Attenuation by antioxidants and anti-inflammatory agents.
Telomeres are a repeated sequence -of bases found at the ends of chromosomes. In humans, this sequence is TTAGGG, which is repeated over 2000 times. Telomeres protect the ends chromosomes from fusion with nearby chromosomes, and allow effective replication of DNA. Each time a cell divides, 25-200 base pairs are lost from the terminal sequence of chromosomes. By becoming truncated during cell division, telomeres protect essential genes from being shortened and thus inactivated. In addition, telomeres are sensitive to inflammation and oxidative stress, which can further promote telomere shortening. Reduction in the length of telomeres leads to the cessation of cell division and thus cellular senescence and apoptosis. This review discusses evidence for the role of oxidative stress and inflammation in regulating the length of telomeres in mammalian cells during senescence. Evidence is presen…

Health relevance of the modification of low grade inflammation in ageing (inflammageing) and the role of nutrition.
Ageing of the global population has become a public health concern with an important socio-economic dimension. Ageing is characterized by an increase in the concentration of inflammatory markers in the bloodstream, a phenomenon that has been termed "inflammageing". The inflammatory response is beneficial as an acute, transient reaction to harmful conditions, facilitating the defense, repair, turnover and adaptation of many tissues. However, chronic and low grade inflammation is likely to be detrimental for many tissues and for normal functions. We provide an overview of low grade inflammation (LGI) and determine the potential drivers and the effects of the "inflamed" phenotype observed in the elderly. We discuss the role of gut microbiota and immune system crosstalk and the gut-brain axis. Then, we focus on major health complications associated with LGI in the elderly, including mental h…

Cerebral hypoperfusion and glucose hypometabolism: Key pathophysiological modulators promote neurodegeneration, cognitive impairment, and Alzheimer's disease.
Aging, hypertension, diabetes, hypoxia/obstructive sleep apnea (OSA), obesity, vitamin B12/folate deficiency, depression, and traumatic brain injury synergistically promote diverse pathological mechanisms including cerebral hypoperfusion and glucose hypometabolism. These risk factors trigger neuroinflammation and oxidative-nitrosative stress that in turn decrease nitric oxide and enhance endothelin, Amyloid-β deposition, cerebral amyloid angiopathy, and blood-brain barrier disruption. Proinflammatory cytokines, endothelin-1, and oxidative-nitrosative stress trigger several pathological feedforward and feedback loops. These upstream factors persist in the brain for decades, upregulating amyloid and tau, before the cognitive decline. These cascades lead to neuronal Ca2+ increase, neurodegeneration, cognitive/memory decline, and Alzheimer's disease (AD). However, strategies are available to…

Epigenetics and Oxidative Stress in Aging.
Aging is a multifactorial process characterized by the progressive loss of physiological functions, leading to an increased vulnerability to age-associated diseases and finally to death. Several theories have been proposed to explain the nature of aging. One of the most known identifies the free radicals produced by the mitochondrial metabolism as the cause of cellular and DNA damage. However, there are also several evidences supporting that epigenetic modifications, such as DNA methylation, noncoding RNAs, and histone modifications, play a critical role in the molecular mechanism of aging. In this review, we explore the significance of these findings and argue how the interlinked effects of oxidative stress and epigenetics can explain the cause of age-related declines.

Sex differences in the gut microbiome-brain axis across the lifespan.
In recent years, the bidirectional communication between the gut microbiome and the brain has emerged as a factor that influences immunity, metabolism, neurodevelopment and behaviour. Cross-talk between the gut and brain begins early in life immediately following the transition from a sterile in utero environment to one that is exposed to a changing and complex microbial milieu over a lifetime. Once established, communication between the gut and brain integrates information from the autonomic and enteric nervous systems, neuroendocrine and neuroimmune signals, and peripheral immune and metabolic signals. Importantly, the composition and functional potential of the gut microbiome undergoes many transitions that parallel dynamic periods of brain development and maturation for which distinct sex differences have been identified. Here, we discuss the sexually dimorphic development, maturatio…

Erectile dysfunction.
Erectile dysfunction is a multidimensional but common male sexual dysfunction that involves an alteration in any of the components of the erectile response, including organic, relational and psychological. Roles for nonendocrine (neurogenic, vasculogenic and iatrogenic) and endocrine pathways have been proposed. Owing to its strong association with metabolic syndrome and cardiovascular disease, cardiac assessment may be warranted in men with symptoms of erectile dysfunction. Minimally invasive interventions to relieve the symptoms of erectile dysfunction include lifestyle modifications, oral drugs, injected vasodilator agents and vacuum erection devices. Surgical therapies are reserved for the subset of patients who have contraindications to these nonsurgical interventions, those who experience adverse effects from (or are refractory to) medical therapy and those who also have penile fib…

Practical Management of Anaesthesia in the Elderly.
The elderly population is rapidly growing and particularly diverse. Ageing leads to reduced organ function and a decline in physiologic reserve. Elderly patients are characterised by great inter-individual variability in physiological function with a high prevalence of chronic disease. In general, older patients have a higher risk of postoperative adverse outcomes, and frailty is a very important risk factor. This review article aims to provide a practical guide to anaesthetic management of the elderly surgical patient. To optimise care, clinicians should be familiar with the typical physiologic changes related to ageing and the implications for anaesthetic management. All anaesthetic techniques, methods and agents can be applied, if tailored to the patient's physiologic and pathologic changes. The elderly are more sensitive to anaesthetics, meaning that desired sedative and analgesic ef…

Brain Insulin Resistance at the Crossroads of Metabolic and Cognitive Disorders in Humans.
Ever since the brain was identified as an insulin-sensitive organ, evidence has rapidly accumulated that insulin action in the brain produces multiple behavioral and metabolic effects, influencing eating behavior, peripheral metabolism, and cognition. Disturbances in brain insulin action can be observed in obesity and type 2 diabetes (T2D), as well as in aging and dementia. Decreases in insulin sensitivity of central nervous pathways, i.e., brain insulin resistance, may therefore constitute a joint pathological feature of metabolic and cognitive dysfunctions. Modern neuroimaging methods have provided new means of probing brain insulin action, revealing the influence of insulin on both global and regional brain function. In this review, we highlight recent findings on brain insulin action in humans and its impact on metabolism and cognition. Furthermore, we elaborate on the most prominent…

Air Pollution Stress and the Aging Phenotype: The Telomere Connection.
Aging is a complex physiological phenomenon. The question why some subjects grow old while remaining free from disease whereas others prematurely die remains largely unanswered. We focus here on the role of air pollution in biological aging. Hallmarks of aging can be grouped into three main categories: genomic instability, telomere attrition, and epigenetic alterations leading to altered mitochondrial function and cellular senescence. At birth, the initial telomere length of a person is largely determined by environmental factors. Telomere length shortens with each cell division and exposure to air pollution as well as low residential greens space exposure is associated with shorter telomere length. Recent studies show that the estimated effects of particulate air pollution exposure on the telomere mitochondrial axis of aging may play an important role in chronic health effects of air po…

Ageing and the telomere connection: An intimate relationship with inflammation.
Telomeres are the heterochromatic repeat regions at the ends of eukaryotic chromosomes, whose length is considered to be a determinant of biological ageing. Normal ageing itself is associated with telomere shortening. Here, critically short telomeres trigger senescence and eventually cell death. This shortening rate may be further increased by inflammation and oxidative stress and thus affect the ageing process. Apart from shortened or dysfunctional telomeres, cells undergoing senescence are also associated with hyperactivity of the transcription factor NF-κB and overexpression of inflammatory cytokines such as TNF-α, IL-6, and IFN-γ in circulating macrophages. Interestingly, telomerase, a reverse transcriptase that elongates telomeres, is involved in modulating NF-κB activity.

A biopsychosocial approach to women's sexual function and dysfunction at midlife: A narrative review.
A satisfying sex life is an important component of overall well-being, but sexual dysfunction is common, especially in midlife women. The aim of this review is (a) to define sexual function and dysfunction, (b) to present theoretical models of female sexual response, (c) to examine longitudinal studies of how sexual function changes during midlife, and (d) to review treatment options. Four types of female sexual dysfunction are currently recognized: Female Orgasmic Disorder, Female Sexual Interest/Arousal Disorder, Genito-Pelvic Pain/Penetration Disorder, and Substance/Medication-Induced Sexual Dysfunction. However, optimal sexual function transcends the simple absence of dysfunction. A biopsychosocial approach that simultaneously considers physical, psychological, sociocultural, and interpersonal factors is necessary to guide research and clinical care regarding women's sexual function.…

Chronic peripheral inflammation, hippocampal neurogenesis, and behavior.
Adult hippocampal neurogenesis is involved in memory and learning, and disrupted neurogenesis is implicated in cognitive impairment and mood disorders, including anxiety and depression. Some long-term peripheral illnesses and metabolic disorders, as well as normal aging, create a state of chronic peripheral inflammation. These conditions are associated with behavioral disturbances linked to disrupted adult hippocampal neurogenesis, such as cognitive impairment, deficits in learning and memory, and depression and anxiety. Pro-inflammatory cytokines released in the periphery are involved in peripheral immune system-to-brain communication by activating resident microglia in the brain. Activated microglia reduce neurogenesis by suppressing neuronal stem cell proliferation, increasing apoptosis of neuronal progenitor cells, and decreasing survival of newly developing neurons and their integra…

The Affective Neuroscience of Aging.
Although aging is associated with clear declines in physical and cognitive processes, emotional functioning fares relatively well. Consistent with this behavioral profile, two core emotional brain regions, the amygdala and ventromedial prefrontal cortex, show little structural and functional decline in aging, compared with other regions. However, emotional processes depend on interacting systems of neurotransmitters and brain regions that go beyond these structures. This review examines how age-related brain changes influence processes such as attending to and remembering emotional stimuli, regulating emotion, and recognizing emotional expressions, as well as empathy, risk taking, impulsivity, behavior change, and attentional focus.

Conclusions about interventions, programs, and approaches for improving executive functions that appear justified and those that, despite much hype, do not.
The 'Executive Functions' (EFs) of inhibitory control, working memory, and cognitive flexibility enable us to think before we act, resist temptations or impulsive reactions, stay focused, reason, problem-solve, flexibly adjust to changed demands or priorities, and see things from new and different perspectives. These skills are critical for success in all life's aspects and are sometimes more predictive than even IQ or socioeconomic status. Understandably, there is great interest in improving EFs. It's now clear they can be improved at any age through training and practice, much as physical exercise hones physical fitness. However, despite claims to the contrary, wide transfer does not seem to occur and 'mindless' aerobic exercise does little to improve EFs. Important questions remain: How much can EFs be improved (are benefits only superficial) and how long can benefits be sustained? Wh…

HIV and ageing: improving quantity and quality of life.
Purpose of review: Evidence-based strategies are needed to address the growing complexity of care of those ageing with HIV so that as life expectancy is extended, quality of life is also enhanced. Recent findings: Modifiable contributing factors to the quantity and quality of life in adults ageing with HIV include: burden of harmful health behaviours, injury from HIV infection, HIV treatment toxicity and general burden of age-associated comorbidities. In turn, these factors contribute to geriatric syndromes including multimorbidity and polypharmacy, physiologic frailty, falls and fragility fractures and cognitive dysfunction, which further compromise the quality of life long before they lead to mortality. Summary: Viral suppression of HIV with combination antiviral therapy has led to increasing longevity but has not enabled a complete return to health among ageing HIV-infected individual…

The role of oxidative and nitrosative stress in accelerated aging and major depressive disorder.
Major depressive disorder (MDD) affects millions of individuals and is highly comorbid with many age associated diseases such as diabetes mellitus, immune-inflammatory dysregulation and cardiovascular diseases. Oxidative/nitrosative stress plays a fundamental role in aging, as well as in the pathogenesis of neurodegenerative/neuropsychiatric disorders including MDD. In this review, we critically review the evidence for an involvement of oxidative/nitrosative stress in acceleration of aging process in MDD. There are evidence of the association between MDD and changes in molecular mechanisms involved in aging. There is a significant association between telomere length, enzymatic antioxidant activities (SOD, CAT, GPx), glutathione (GSH), lipid peroxidation (MDA), nuclear factor κB, inflammatory cytokines with MDD. Major depression also is characterized by significantly lower concentration o…

Sleep: A Novel Mechanistic Pathway, Biomarker, and Treatment Target in the Pathology of Alzheimer's Disease?
Sleep disruption appears to be a core component of Alzheimer's disease (AD) and its pathophysiology. Signature abnormalities of sleep emerge before clinical onset of AD. Moreover, insufficient sleep facilitates accumulation of amyloid-β (Aβ), potentially triggering earlier cognitive decline and conversion to AD. Building on such findings, this review has four goals: evaluating (i) associations and plausible mechanisms linking non-rapid-eye-movement (NREM) sleep disruption, Aβ, and AD; (ii) a role for NREM sleep disruption as a novel factor linking cortical Aβ to impaired hippocampus-dependent memory consolidation; (iii) the potential diagnostic utility of NREM sleep disruption as a new biomarker of AD; and (iv) the possibility of sleep as a new treatment target in aging, affording preventative and therapeutic benefits.

Promoting health and longevity through diet: from model organisms to humans.
Reduced food intake, avoiding malnutrition, can ameliorate aging and aging-associated diseases in invertebrate model organisms, rodents, primates, and humans. Recent findings indicate that meal timing is crucial, with both intermittent fasting and adjusted diurnal rhythm of feeding improving health and function, in the absence of changes in overall intake. Lowered intake of particular nutrients rather than of overall calories is also key, with protein and specific amino acids playing prominent roles. Nutritional modulation of the microbiome can also be important, and there are long-term, including inter-generational, effects of diet. The metabolic, molecular, and cellular mechanisms that mediate both improvement in health during aging to diet and genetic variation in the response to diet are being identified. These new findings are opening the way to specific dietary and pharmacological …

So! What's aging? Is cardiovascular aging a disease?
"Inside every old person is a young person wondering what happened." So, what is aging? Aging is a manifestation of progressive, time-dependent failure of molecular mechanisms that create disorder within a system of DNA and its environment (nuclear, cytosolic, tissue, organ, organism, other organisms, society, terra firma, atmosphere, universe). Continuous signaling, transmitted with different kinetics across each of these environments, confers a "mutual enslavement" that creates ordered functions among the components within the system. Accrual of this molecular disorder over time, i.e. during aging, causes progressive changes in the structure and function of the heart and arteries that are quite similar in humans, non-human primates, rabbits and rats that compromise cardiovascular reserve function, and confer a marked risk for incident cardiovascular disease. Nearly all aspects of signa…

Perceived social isolation, evolutionary fitness and health outcomes: a lifespan approach.
Sociality permeates each of the fundamental motives of human existence and plays a critical role in evolutionary fitness across the lifespan. Evidence for this thesis draws from research linking deficits in social relationship--as indexed by perceived social isolation (i.e. loneliness)--with adverse health and fitness consequences at each developmental stage of life. Outcomes include depression, poor sleep quality, impaired executive function, accelerated cognitive decline, unfavourable cardiovascular function, impaired immunity, altered hypothalamic pituitary-adrenocortical activity, a pro-inflammatory gene expression profile and earlier mortality. Gaps in this research are summarized with suggestions for future research. In addition, we argue that a better understanding of naturally occurring variation in loneliness, and its physiological and psychological underpinnings, in non-human s…

Calorie restriction and methionine restriction in control of endogenous hydrogen sulfide production by the transsulfuration pathway.
H2S is a gas easily identified by its distinctive odor. Although environmental exposure to H2S has been viewed alternately as therapeutic or toxic through the centuries, H2S has recently regained recognition for its numerous beneficial biological effects. Most experiments documenting such benefits, including improved glucose tolerance, increased stress resistance, and even lifespan extension, are based on exposure of experimental organisms to exogenous sources of H2S. However, appreciation is growing for the importance of H2S produced endogenously by the evolutionary conserved transsulfuration pathway (TSP) in health and longevity. Recent data implicate H2S produced by the TSP in pleiotropic benefits of dietary restriction (DR), or reduced nutrient/energy intake without malnutrition. DR, best known as the most reliable way to extend lifespan in a wide range of experimental organisms, inc…

Subjective wellbeing, health, and ageing.
Subjective wellbeing and health are closely linked to age. Three aspects of subjective wellbeing can be distinguished-evaluative wellbeing (or life satisfaction), hedonic wellbeing (feelings of happiness, sadness, anger, stress, and pain), and eudemonic wellbeing (sense of purpose and meaning in life). We review recent advances in the specialty of psychological wellbeing, and present new analyses about the pattern of wellbeing across ages and the association between wellbeing and survival at older ages. The Gallup World Poll, a continuing survey in more than 160 countries, shows a U-shaped relation between evaluative wellbeing and age in high-income, English speaking countries, with the lowest levels of wellbeing in ages 45-54 years. But this pattern is not universal. For example, respondents from the former Soviet Union and eastern Europe show a large progressive reduction in wellbeing …

The role of sirtuins in cardiac disease.
Modification of histones is one of the important mechanisms of epigenetics, in which genetic control is determined by factors other than an individual's DNA sequence. Sirtuin family proteins, which are class III histone deacetylases, were originally identified as gene silencers that affect the mating type of yeast, leading to the name "silent mating-type information regulation 2" (SIR2). They are characterized by their requirement of nicotinamide adenine dinucleotide for their enzyme activity, unlike other classes of histone deacetylases. Sirtuins have been traditionally linked to longevity and the beneficial effects of calorie restriction and DNA damage repair. Recently, sirtuins have been shown to be involved in a wide range of physiological and pathological processes, including aging, energy responses to low calorie availability, and stress resistance, as well as apoptosis and inflamm…
