The Role Of Capillaries In The Lesser Ailments Of Old Age And In Alzheimer's Disease And Vascular Dementia: The Potential Of Pro-Therapeutic Angiogenesis, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Apart from chronic diseases (arthritis, diabetes, etc.), old age is generally characterized by three lesser ailments: muscle weakness, minor memory lapses, and cold intolerance. This trio of complaints may have a common, underlying cause, namely, the age-associated reduced microcirculation in muscles, brain, skin, and elsewhere in the body. The Angiogenesis Hypothesis proposes that old age is in part a deficiency disease due to the decline in angiogenic (AG) factors, resulting in a reduced capillary density (CD) throughout the body. Over fifty published papers document waning levels of AG factors and/or decreased CD in various organ systems of aged animals and …

Two-Arm Randomized Pilot Intervention Trial To Decrease Sitting Time And Increase Sit-To-Stand Transitions In Working And Non-Working Older Adults., Jacqueline Kerr, Michelle Takemoto, Khalisa Bolling, Andrew Atkin, Jordan A. Carlson, Dori Rosenberg, Katie Crist, Suneeta Godbole, Brittany Lewars, Claudia Pena, Gina Merchant

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Excessive sitting has been linked to poor health. It is unknown whether reducing total sitting time or increasing brief sit-to-stand transitions is more beneficial. We conducted a randomized pilot study to assess whether it is feasible for working and non-working older adults to reduce these two different behavioral targets.

METHODS: Thirty adults (15 workers and 15 non-workers) age 50-70 years were randomized to one of two conditions (a 2-hour reduction in daily sitting or accumulating 30 additional brief sit-to-stand transitions per day). Sitting time, standing time, sit-to-stand transitions and stepping were assessed by a thigh worn inclinometer (activPAL). Participants …

Rapamycin Rescues Vascular, Metabolic And Learning Deficits In Apolipoprotein E4 Transgenic Mice With Pre-Symptomatic Alzheimer’S Disease, Ai-Ling Lin, Jordan B. Jahrling, Wei Zhang, Nicholas Derosa, Vikas Bakshi, Peter Romero, Veronica Galvan, Arlan Richardson

Sanders-Brown Center on Aging Faculty Publications

Apolipoprotein E ɛ4 allele is a common susceptibility gene for late-onset Alzheimer's disease. Brain vascular and metabolic deficits can occur in cognitively normal apolipoprotein E ɛ4 carriers decades before the onset of Alzheimer's disease. The goal of this study was to determine whether early intervention using rapamycin could restore neurovascular and neurometabolic functions, and thus impede pathological progression of Alzheimer's disease-like symptoms in pre-symptomatic Apolipoprotein E ɛ4 transgenic mice. Using in vivo, multimodal neuroimaging, we found that apolipoprotein E ɛ4 mice treated with rapamycin had restored cerebral blood flow, blood–brain barrier integrity and glucose metabolism, compared …

The Happy Older Latinos Are Active (Hola) Health Promotion And Prevention Study: Study Protocol For A Pilot Randomized Controlled Trial, Daniel E. Jimenez, Charles F. Reynolds, Margarita Alegría, Philip Harvey, Stephen Bartels

Dartmouth Scholarship

Results of previous studies attest to the greater illness burden of common mental disorders (anxiety and depression) in older Latinos and the need for developing preventive interventions that are effective, acceptable, and scalable. Happy Older Latinos are Active (HOLA) is a newly developed intervention that uses a community health worker (CHW) to lead a health promotion program in order to prevent common mental disorders among at-risk older Latinos. This pilot study tests the feasibility and acceptability of delivering HOLA to older, at-risk Latinos.

Methods/Design: HOLA is a multi-component, health promotion intervention funded by the National Institute of Mental Health (NIMH). …

Early Shifts Of Brain Metabolism By Caloric Restriction Preserve White Matter Integrity And Long-Term Memory In Aging Mice, Janet Guo, Vikas Bakshi, Ai-Ling Lin

Sanders-Brown Center on Aging Faculty Publications

Preservation of brain integrity with age is highly associated with lifespan determination. Caloric restriction (CR) has been shown to increase longevity and healthspan in various species; however, its effects on preserving living brain functions in aging remain largely unexplored. In the study, we used multimodal, non-invasive neuroimaging (PET/MRI/MRS) to determine in vivo brain glucose metabolism, energy metabolites, and white matter structural integrity in young and old mice fed with either control or 40% CR diet. In addition, we determined the animals’ memory and learning ability with behavioral assessments. Blood glucose, blood ketone bodies, and body weight were also measured. We …

Mice Deficient In Endothelial Α5 Integrin Are Profoundly Resistant To Experimental Ischemic Stroke, Jill Roberts, Leon De Hoog, Gregory J. Bix

Sanders-Brown Center on Aging Faculty Publications

Stroke is a disease in dire need of better therapies. We have previously shown that a fragment of the extracellular matrix proteoglycan, perlecan, has beneficial effects following cerebral ischemia via the α5β1 integrin receptor. We now report that endothelial cell selective α5 integrin deficient mice (α5 KO) are profoundly resistant to ischemic infarct after transient middle cerebral artery occlusion. Specifically, α5 KOs had little to no infarct 2–3 days post-stroke, whereas controls had an increase in mean infarct volume over the same time period as expected. Functional outcome is also improved in the α5 KOs compared with controls. Importantly, no …

Engaging Older Adults To Build Social Capital, Beverly K. Lunsford, Danielle Janes

Nursing Faculty Publications

Countries are considering the healthcare implications as the proportion of older adults increases, including rising healthcare costs and resources needed as more adults want to "age in place" or continue living in the community. More in home resources and support services will be needed for older adults to continue living independently at homes. Older adults are an incredibly untapped resource with a continuing need to contribute to society and a willingness to help others. Older adults are working longer than ever before, so they have the potential to build their own social capital for meeting the needs of aging colleagues. …

Abcc9/Sur2 In The Brain: Implications For Hippocampal Sclerosis Of Aging And A Potential Therapeutic Target, Peter T. Nelson, Gregory A. Jicha, Wang-Xia Wang, Eseosa T. Ighodaro, Sergey C. Artiushin, Colin G. Nichols, David W. Fardo

Sanders-Brown Center on Aging Faculty Publications

The ABCC9 gene and its polypeptide product, SUR2, are increasingly implicated in human neurologic disease, including prevalent diseases of the aged brain. SUR2 proteins are a component of the ATP-sensitive potassium (“K _ATP ”) channel, a metabolic sensor for stress and/or hypoxia that has been shown to change in aging. The K _ATP channel also helps regulate the neurovascular unit. Most brain cell types express SUR2, including neurons, astrocytes, oligodendrocytes, microglia, vascular smooth muscle, pericytes, and endothelial cells. Thus it is not surprising that ABCC9 gene variants are associated with risk for human brain diseases. For example, Cantu syndrome is …

Dynapenic Obesity And The Effect On Long-Term Physical Function And Quality Of Life: Data From The Osteoarthritis Initiative, John A. Batsis, Alicia J. Zbehlik, Dawna Pidgeon, Stephen J. Bartels

Dartmouth Scholarship

Obesity is associated with functional impairment, institutionalization, and increased mortality risk in elders. Dynapenia is defined as reduced muscle strength and is a known independent predictor of adverse events and disability. The synergy between dynapenia and obesity leads to worse outcomes than either independently. We identified the impact of dynapenic obesity in a cohort at risk for and with knee osteoarthritis on function.

Time-Dependent Effects Of Cx3cr1 In A Mouse Model Of Mild Traumatic Brain Injury, Heidi Y. Febinger, Hannah E. Thomasy, Maria N. Pavlova, Kristyn M. Ringgold, Paulien R. Barf, Amrita M. George, Jenna N. Grillo, Adam D. Bachstetter, Jenny A. Garcia, Astrid E. Cardona, Mark R. Opp, Carmelina Gemma

Sanders-Brown Center on Aging Faculty Publications

BACKGROUND: Neuroinflammation is an important secondary mechanism that is a key mediator of the long-term consequences of neuronal injury that occur in traumatic brain injury (TBI). Microglia are highly plastic cells with dual roles in neuronal injury and recovery. Recent studies suggest that the chemokine fractalkine (CX3CL1, FKN) mediates neural/microglial interactions via its sole receptor CX3CR1. CX3CL1/CX3CR1 signaling modulates microglia activation, and depending upon the type and time of injury, either protects or exacerbates neurological diseases.

METHODS: In this study, mice deficient in CX3CR1 were subjected to mild controlled cortical impact injury (CCI), a model of TBI. We evaluated …
