Olfactory Thresholds Of The U.S. Population Of Home-Dwelling Older Adults: Development And Validation Of A Short, Reliable Measure, David W. Kern, L Phillip Schumm, Kristen E. Wroblewski, Jayant M. Pinto, Thomas Hummel

Psychology & Gerontology Faculty Publications

Current methods of olfactory sensitivity testing are logistically challenging and therefore infeasible for use in in-home surveys and other field settings. We developed a fast, easy and reliable method of assessing olfactory thresholds, and used it in the first study of olfactory sensitivity in a nationally representative sample of U.S. home-dwelling older adults. We validated our method via computer simulation together with a model estimated from 590 normosmics. Simulated subjects were assigned n-butanol thresholds drawn from the estimated normosmic distribution and based on these and the model, we simulated administration of both the staircase and constant stimuli methods. Our …

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterized by the frequent association of disease outside the lung. The objective of this study was to determine the presence of biomechanical gait abnormalities in COPD patients compared to healthy controls while well rested and without rest.

METHODS: Patients with COPD (N = 17) and aged-matched, healthy controls (N = 21) walked at their self-selected pace down a 10-meter walkway while biomechanical gait variables were collected. A one-minute rest was given between each of the five collected trials to prevent tiredness (REST condition). Patients with COPD then walked at a self-selected pace on …

Posterior Approach To Kidney Dissection: An Old Surgical Approach For Integrated Medical Curricula, Frank J. Daly, David L. Bolender, Deepali Jain, Sheryl Uyeda, Todd M. Hoagland

Biomedical Sciences Faculty Publications

Integrated medical curricular changes are altering the historical regional anatomy approach to abdominal dissection. The renal system is linked physiologically and biochemically to the cardiovascular and respiratory systems, yet anatomist often approach the urinary system as part of the abdomen and pelvic regions. As part of an integrated curriculum, the renal system must be covered relatively quickly after the thorax in the cadaver lab, often without the opportunity to fully appreciate the rest of the abdominal contents. This paper provides dissection instructions that follow the one of the historical surgical approaches for nephrectomy, including preservation of the posterior abdominal wall …

The Effect Of Active Video Games On The Heart Rate Of Older Adults, Yeon Bai, Shahla M. Wunderlich, Diane M. Hanel

Nicotine Receptors Mediating Sensorimotor Gating And Its Enhancement By Systemic Nicotine, Farena Pinnock, Daniel Bosch, Tyler Brown, Nadine Simons, John R. Yeomans, Cleusa Deoliveira, Susanne Schmid

Anatomy and Cell Biology Publications

Prepulse inhibition (PPI) of startle occurs when intensity stimuli precede stronger startle-inducing stimuli by 10–1000 ms. PPI deficits are found in individuals with schizophrenia and other psychiatric disorders, and they correlate with other cognitive impairments. Animal research and clinical studies have demonstrated that both PPI and cognitive function can be enhanced by nicotine. PPI has been shown to be mediated, at least in part, by mesopontine cholinergic neurons that project to pontine startle neurons and activate muscarinic and potentially nicotine receptors (nAChRs). The subtypes and anatomical location of nAChRs involved in mediating and modulating PPI remain unresolved. We tested the …

The Role Of Il-27 In Susceptibility To Post-Influenza Staphylococcus Aureus Pneumonia, Keven M. Robinson, Benjamin Lee, Erich V Scheller, Sivanarayana Mandalapu, Richard I. Enelow

Dartmouth Scholarship

Influenza is a common respiratory virus and Staphylococcus aureus frequently causes secondary pneumonia during influenza infection, leading to increased morbidity and mortality. Influenza has been found to attenuate subsequent Type 17 immunity, enhancing susceptibility to secondary bacterial infections. IL-27 is known to inhibit Type 17 immunity, suggesting a potential critical role for IL-27 in viral and bacterial co-infection.

Protein Composition And Movements Of Membrane Swellings Associated With Primary Cilia, Ashraf M. Mohieldin, Hanan S. Haymour, Shao T. Lo, Wissam A. Aboualaiwi, Kimberly F. Atkinson, Christopher J. Ward, Min Gao, Oliver Wessely, Surya M. Nauli

Pharmacy Faculty Articles and Research

Dysfunction of many ciliary proteins has been linked to a list of diseases, from cystic kidney to obesity and from hypertension to mental retardation. We previously proposed that primary cilia are unique communication organelles that function as microsensory compartments that house mechanosensory molecules. Here we report that primary cilia exhibit membrane swellings, which based on their unique ultrastructure and motility, could be mechanically regulated by fluid-shear stress. Together with the ultrastructure analysis of the bulb, which contains monosialodihexosylganglioside (GM3), our results show that ciliary membrane swelling has a distinctive set of functional proteins, including GM3 synthase (GM3S), bicaudal-c1 (Bicc1) and …

Methods

We retrospectively reviewed 242 consecutive patients [mean age 74 ± 12 years; 66.9% male] who underwent lead revision that resulted in an abandoned lead from January 2005 to June 2010. Patients were placed in a cohort based on number of leads after last recorded procedure (Group A: ≤2 [n=58]; Group B: 3-4 [n=168]; …

Association Between Body Surface Area And Outcomes After Percutaneous Coronary Intervention, Kambiz Shetabi, Tonga Nfor, Fengyi Shen, Anjan Gupta, Tanvir Bajwa, Suhail Allaqaband

Journal of Patient-Centered Research and Reviews

Purpose

Obesity is a well-known risk factor for adverse cardiovascular events, but some studies suggest higher body mass index (BMI) is associated with better outcomes after ST-segment elevation myocardial infarction (STEMI). We sought to determine the effect of body surface area (BSA) on adverse events after primary percutaneous coronary intervention (PCI) for STEMI and how this relates to the reported obesity paradox theory.

Methods

We analyzed a prospective registry of patients with STEMI who underwent primary PCI at a tertiary care hospital from 2003 to 2009. Post-PCI complications and 1-year all-cause mortality were compared across BSA quartiles. Relationship with 1-year …

Designer Receptors Enhance Memory In A Mouse Model Of Down Syndrome, Ashley M. Fortress, Eric D. Hamlett, Elena M. Vazey, Gary Aston-Jones, Wayne A. Cass, Heather A. Boger, Ann-Charlotte E. Granholm

Neuroscience Faculty Publications

Designer receptors exclusively activated by designer drugs (DREADDs) are novel and powerful tools to investigate discrete neuronal populations in the brain. We have used DREADDs to stimulate degenerating neurons in a Down syndrome (DS) model, Ts65Dn mice. Individuals with DS develop Alzheimer's disease (AD) neuropathology and have elevated risk for dementia starting in their 30s and 40s. Individuals with DS often exhibit working memory deficits coupled with degeneration of the locus coeruleus (LC) norepinephrine (NE) neurons. It is thought that LC degeneration precedes other AD-related neuronal loss, and LC noradrenergic integrity is important for executive function, working memory, and attention. …

The Use Of Stem Cells In Burn Wound Healing: A Review, Fadi Ghieh, Rosalyn A. Jurjus, Amir Ibrahim, Alice Gerges Geagea, Hisham Daouk, Bassel El Baba, Sana Cham, Michel Matar, Wadih Zein, Abdo Jurjus

Anatomy and Regenerative Biology Faculty Publications

Burn wound healing involves a series of complex processes which are subject to intensive investigations to improve the outcomes, in particular, the healing time and the quality of the scar. Burn injuries, especially severe ones, are proving to have devastating effects on the affected patients. Stem cells have been recently applied in the field to promote superior healing of the wounds. Not only have stem cells been shown to promote better and faster healing of the burn wounds, but also they have decreased the inflammation levels with less scar progression and fibrosis. This review aims to highlight the beneficial therapeutic …

Skeletal Muscle Fibrosis In The Mdx/Utrn Plus /- Mouse Validates Its Suitability As A Murine Model Of Duchenne Muscular Dystrophy, Kelly M. Gutpell, William T. Hrinivich, Lisa M. Hoffman

Anatomy and Cell Biology Publications

Various therapeutic approaches have been studied for the treatment of Duchenne muscular dystrophy (DMD), but none of these approaches have led to significant long-term effects in patients. One reason for this observed inefficacy may be the use of inappropriate animal models for the testing of therapeutic agents. The mdx mouse is the most widely used murine model of DMD, yet it does not model the fibrotic progression observed in patients. Other murine models of DMD are available that lack one or both alleles of utrophin, a functional analog of dystrophin. The aim of this study was to compare fibrosis and …

Spatial And Temporal Characteristics Of Error-Related Activity In The Human Brain, Maital Neta, Francis M. Miezin, Steven M. Nelson, Joseph W. Dubis, Nico U.F. Dosenbach, Bradley L. Schlaggar, Steven E. Petersen

Center for Brain, Biology, and Behavior: Faculty Publications

A number of studies have focused on the role of specific brain regions, such as the dorsal anterior cingulate cortex during trials on which participants make errors, whereas others have implicated a host of more widely distributed regions in the human brain. Previous work has proposed that there are multiple cognitive control networks, raising the question of whether error-related activity can be found in each of these networks. Thus, to examine error-related activity broadly, we conducted a meta-analysis consisting of 12 tasks that included both error and correct trials. These tasks varied by stimulus input (visual, auditory), response output (button …

Developmental Remodeling Of Relay Cells In The Dorsal Lateral Geniculate Nucleus In The Absence Of Retinal Input, Rana N. El-Danaf, Thomas E. Krahe, Emily K. Dilger, Martha E. Bickford, Michael A. Fox, William Guido

Anatomy and Neurobiology Publications

Background

The dorsal lateral geniculate nucleus (dLGN) of the mouse has been an important experimental model for understanding thalamic circuit development. The developmental remodeling of retinal projections has been the primary focus, however much less is known about the maturation of their synaptic targets, the relay cells of the dLGN. Here we examined the growth and maturation of relay cells during the first few weeks of life and addressed whether early retinal innervation affects their development. To accomplish this we utilized themath5 null (math5−/−) mouse, a mutant lacking retinal ganglion cells and central projections.

Microglia Processes Associate With Diffusely Injured Axons Following Mild Traumatic Brain Injury In The Micro Pig, Audrey D. Lafrenaye, Masak Todani, Susan A. Walker, John T. Povlishock

Anatomy and Neurobiology Publications

Background

Mild traumatic brain injury (mTBI) is an all too common occurrence that exacts significant personal and societal costs. The pathophysiology of mTBI is complex, with reports routinely correlating diffuse axonal injury (DAI) with prolonged morbidity. Progressive chronic neuroinflammation has also recently been correlated to morbidity, however, the potential association between neuroinflammatory microglia and DAI is not well understood. The majority of studies exploring neuroinflammatory responses to TBI have focused on more chronic phases of injury involving phagocytosis associated with Wallerian change. Little, however, is known regarding the neuroinflammatory response seen acutely following diffuse mTBI and its potential relationship to …

Acetylcholine Release In Mouse Hippocampal Ca1 Preferentially Activates Inhibitory-Selective Interneurons Via Α4Β2* Nicotinic Receptor Activation, L. Andrew Bell, Karen A. Bell, A. Rory Mcquiston

Anatomy and Neurobiology Publications

Acetylcholine (ACh) release onto nicotinic receptors directly activates subsets of inhibitory interneurons in hippocampal CA1. However, the specific interneurons activated and their effect on the hippocampal network is not completely understood. Therefore, we investigated subsets of hippocampal CA1 interneurons that respond to ACh release through the activation of nicotinic receptors and the potential downstream effects this may have on hippocampal CA1 network function. ACh was optogenetically released in mouse hippocampal slices by expressing the excitatory optogenetic protein oChIEF-tdTomato in medial septum/diagonal band of Broca cholinergic neurons using Cre recombinase-dependent adeno-associated viral mediated transfection. The actions of optogenetically released ACh were …

Proteomics: In Pursuit Of Effective Traumatic Brain Injury Therapeutics, Pavel N. Lizhnyak, Andrew K. Ottens

Anatomy and Neurobiology Publications

Effective traumatic brain injury (TBI) therapeutics remain stubbornly elusive. Efforts in the field have been challenged by the heterogeneity of clinical TBI, with greater complexity among underlying molecular phenotypes than initially conceived. Future research must confront the multitude of factors comprising this heterogeneity, representing a big data challenge befitting the coming informatics age. Proteomics is poised to serve a central role in prescriptive therapeutic development, as it offers an efficient endpoint within which to assess post-TBI biochemistry. We examine rationale for multifactor TBI proteomic studies and the particular importance of temporal profiling in defining biochemical sequences and guiding therapeutic development. …

Gabaergic Regulation Of Cerebellar Ng2-Cell Development Is Altered In Perinatal White Matter Injury, Marzieh Zonouzi, Joseph Scafidi, Peijun Li, Brian Mcellin, Jorge Edwards, Jeffrey L. Dupree, Lloyd Harvey, Dandan Sun, Christian A. Hübner, Stuart G. Cull-Candy, Mark Farrant, Vittorio Gallo

Anatomy and Neurobiology Publications

Diffuse white matter injury (DWMI), a leading cause of neurodevelopmental disabilities in preterm infants, is characterized by reduced oligodendrocyte formation. Oligodendrocyte precursor cells (NG2-cells) are exposed to various extrinsic regulatory signals, including the neurotransmitter GABA. We investigated GABAergic signaling to cerebellar white matter NG2-cells in a mouse model of DWMI (chronic neonatal hypoxia). We found that hypoxia caused a loss of GABAA receptor-mediated synaptic input to NG2-cells, extensive proliferation of these cells and delayed oligodendrocyte maturation, leading to dysmyelination. Treatment of control mice with a GABAA receptor antagonist or deletion of the chloride-accumulating transporter NKCC1 mimicked the effects of hypoxia. …

With the expectations of accountability by consumers and third party payors for the efficacy of physical therapy practice, there has been a significant increase in the push to develop outcome measures in rehabilitation. One type of these measures, patient-reported outcome measures (PROs), are becoming increasingly more common in clinical practice. The American Physical Therapy Association’s Guide to Physical Therapist Practice 3rd edition includes outcomes assessment as an integral part of the Patient and Client Management model, and delineates that appropriate tests and measures depend upon established psychometric properties of the measurement.1 The Section on Research formed the Evidence Database to …

Once Upon A Microscopic Slide: The Story Of Histology, Inaya Hussein, Mohamad Raad, Rawan Safa, Rosalyn A. Jurjus, Abdo Jurjus

Anatomy and Regenerative Biology Faculty Publications

For centuries, histology has maintained its remarkable place in the medical curriculum. However, its teaching has been influenced by the new technological advancement that has reshaped medicine teaching into a more modern student-friendly form. Since its inception in the 18th century, the discipline of histology has progressed hand in hand with the advancements in microscopy and microscopic technologies, including immunohistochemistry. In the traditional curriculum of USA medical schools, especially after the first Flexner’s report of 1910, histology was considered as very essential topic for a physician studying the “Art and Science” of medicine. In this era, the teaching relied more …

High Fat High Cholesterol Diet (Western Diet) Aggravates Atherosclerosis, Hyperglycemia And Renal Failure In Nephrectomized Ldl Receptor Knockout Mice: Role Of Intestine Derived Lipopolysaccharide, Siddhartha S. Ghosh, Samuel Righi, Richard Krieg, Le Kang, Daniel Carl, Jing Wang, H. Davis Massey, Domenic A. Sica, Todd W. B. Gehr, Shobha Ghosh

Anatomy and Neurobiology Publications

A high fat meal, frequently known as western diet (WD), exacerbates atherosclerosis and diabetes. Both these diseases are frequently associated with renal failure. Recent studies have shown that lipopolysaccharide (LPS) leaks into the circulation from the intestine in the setting of renal failure and after WD. However, it is not clear how renal function and associated disorders are affected by LPS. This study demonstrates that circulatory LPS exacerbates renal insufficiency, atherosclerosis and glucose intolerance. Renal insufficiency was induced by 2/3 nephrectomy in LDL receptor knockout mice. Nx animals were given normal diet (Nx) or WD (Nx+WD). The controls were sham …
