A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson
A Narrative Review Of Yoga And Mindfulness As Complementary Therapies For Addiction., Surbhi Khanna, Jeffrey M Greeson
College of Science & Mathematics Departmental Research
This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles and practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention toward one's health, while acknowledging the spiritual aspects of one's nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness …

The Cyclomodulin Cycle Inhibiting Factor (Cif) Alters Cullin Neddylation Dynamics, Tasha B. Toro, J. I. Toth, M. D. Petroski
Faculty and Staff Publications
The bacterial effector protein cycle inhibiting factor (CIF) converts glutamine 40 of NEDD8 to glutamate (Q40E), causing cytopathic effects and inhibiting cell proliferation. Although these have been attributed to blocking the functions of cullin-RING ubiquitin ligases, how CIF modulates NEDD8-dependent signaling is unclear. Here we use conditional NEDD8-dependent yeast to explore the effects of CIF on cullin neddylation. Although CIF causes cullin deneddylation and the generation of free NEDD8 Q40E, inhibiting the COP9 signalosome (CSN) allows Q40E to form only on NEDD8 attached to cullins. In the presence of the CSN, NEDD8 Q40E is removed from cullins more rapidly than …
Key Genes For Modulating Information Flow Play A Temporal Role As Breast Tumor Coexpression Networks Are Dynamically Rewired By Letrozole, Nadia M. Penrod, Jason H. Moore
Key Genes For Modulating Information Flow Play A Temporal Role As Breast Tumor Coexpression Networks Are Dynamically Rewired By Letrozole, Nadia M. Penrod, Jason H. Moore
Dartmouth Scholarship
Genes do not act in isolation but instead as part of complex regulatory networks. To understand how breast tumors adapt to the presence of the drug letrozole, at the molecular level, it is necessary to consider how the expression levels of genes in these networks change relative to one another. Using transcriptomic data generated from sequential tumor biopsy samples, taken at diagnosis, following 10-14 days and following 90 days of letrozole treatment, and a pairwise partial orrelation statistic, we build temporal gene coexpression networks. We characterize the structure of each network and identify genes that hold prominent positions for maintaining …
Continuous Correction Of Differential Path Length Factor In Near-Infrared Spectroscopy, Tanveer Talukdar, Jason H. Moore, Solomon G. Diamond
Continuous Correction Of Differential Path Length Factor In Near-Infrared Spectroscopy, Tanveer Talukdar, Jason H. Moore, Solomon G. Diamond
Dartmouth Scholarship
In continuous-wave near-infrared spectroscopy (CW-NIRS), changes in the concentration of oxyhemoglobin and deoxyhemoglobin can be calculated by solving a set of linear equations from the modified Beer-Lambert Law. Cross-talk error in the calculated hemodynamics can arise from inaccurate knowledge of the wavelength-dependent differential path length factor (DPF). We apply the extended Kalman filter (EKF) with a dynamical systems model to calculate relative concentration changes in oxy- and deoxyhemoglobin while simultaneously estimating relative changes in DPF. Results from simulated and experimental CW-NIRS data are compared with results from a weighted least squares (WLSQ) method. The EKF method was found to effectively …
Cinacalcet As Adjunctive Therapy For Hereditary 1,25-Dihydroxyvitamin D-Resistant Rickets., Tarak Srivastava, Uri S. Alon
Cinacalcet As Adjunctive Therapy For Hereditary 1,25-Dihydroxyvitamin D-Resistant Rickets., Tarak Srivastava, Uri S. Alon
Manuscripts, Articles, Book Chapters and Other Papers
Secondary hyperparathyroidism from inadequate calcium absorption in the gut, is the underlying pathophysiology for rachitic changes in hereditary vitamin D-resistant rickets (HVDRR). We describe a novel use of Cinacalcet to treat a child with HVDRR in whom conventional modes of therapy had to be discontinued. Cinacalcet therapy with high-dose oral calcium effectively normalized the metabolic abnormalities and bone condition. The relative ease of administration of the calcimimetic as a once- or twice-daily oral preparation, compared with traditional intravenous calcium administration, should encourage its move to the frontline of treatment of the disorder.

BACKGROUND: Compared with elective surgical procedures, emergency procedures are associated with higher cost, morbidity, and mortality. This study seeks to investigate potential state-by-state variations in the incidence of emergent versus elective colon resections.
METHODS: A retrospective analysis of all adult patients (aged ≥18 years) included in the Nationwide Inpatient Sample from 2005 to 2009 who underwent hemicolectomy (right or left) or sigmoidectomy was conducted. Discharge-level weights were applied, and generalized linear models were used to assess the odds of a patient undergoing emergent versus elective colon surgery nationally and for each state after adjusting for patient and hospital factors. Odds …
A Study Of Small Rnas From Cerebral Neocortex Of Pathology-Verified Alzheimer's Disease, Dementia With Lewy Bodies, Hippocampal Sclerosis, Frontotemporal Lobar Dementia, And Non-Demented Human Controls, Sébastien S. Hébert, Wang-Xia Wang, Qi Zhu, Peter T. Nelson

Sanders-Brown Center on Aging Faculty Publications
MicroRNAs (miRNAs) are small (20-22 nucleotides) regulatory non-coding RNAs that strongly influence gene expression. Most prior studies addressing the role of miRNAs in neurodegenerative diseases (NDs) have focused on individual diseases such as Alzheimer's disease (AD), making disease-to-disease comparisons impossible. Using RNA deep sequencing, we sought to analyze in detail the small RNAs (including miRNAs) in the temporal neocortex gray matter from non-demented controls (n = 2), AD (n = 5), dementia with Lewy bodies (n = 4), hippocampal sclerosis of aging (n = 4), and frontotemporal lobar dementia (FTLD) (n = 5) cases, together accounting for the most prevalent …

BACKGROUND: Dens fractures are relatively common in the elderly. The treatment of Type-II dens fractures remains controversial. The aim of this multicenter prospective cohort study was to compare outcomes (assessed with use of validated clinical measures) and complications of nonsurgical and surgical treatment of Type-II dens fractures in patients sixty-five years of age or older.
METHODS: One hundred and fifty-nine patients with a Type-II dens fracture were enrolled in a multicenter prospective study. Subjects were treated either surgically (n = 101) or nonsurgically (n = 58) as determined by the treatment preferences of the treating physicians and the patients. The …

Side Chain Requirements For Affinity And Specificity In D5, An Hiv-1 Antibody Derived From The Vh1-69 Germline Segment, Alex Stewart, Joseph S. Harrison, Lauren K. Regula, Jonathan R. Lai
College of the Pacific Faculty Articles
BACKGROUND: Analysis of factors contributing to high affinity antibody-protein interactions provides insight into natural antibody evolution, and guides the design of antibodies with new or enhanced function. We previously studied the interaction between antibody D5 and its target, a designed protein based on HIV-1 gp41 known as 5-Helix, as a model system [Da Silva, G. F.; Harrison, J. S.; Lai, J. R., Biochemistry, 2010, 49, 5464-5472]. Antibody D5 represents an interesting case study because it is derived from the VH1-69 germline segment; this germline segment is characterized by a hydrophobic second heavy chain complementarity determining region (HCDR2) that constitutes the …

While the induction of a neutralizing antibody response against HIV remains a daunting goal, data from both natural infection and vaccine-induced immune responses suggest that it may be possible to induce antibodies with enhanced Fc effector activity and improved antiviral control via vaccination. However, the specific features of naturally induced HIV-specific antibodies that allow for the potent recruitment of antiviral activity and the means by which these functions are regulated are poorly defined. Because antibody effector functions are critically dependent on antibody Fc domain glycosylation, we aimed to define the natural glycoforms associated with robust Fc-mediated antiviral activity. We demonstrate …
Geographic Variation In Chin Shape Challenges The Universal Facial Attractiveness Hypothesis, Zaneta M. Thayer, Seth D. Dobson
Geographic Variation In Chin Shape Challenges The Universal Facial Attractiveness Hypothesis, Zaneta M. Thayer, Seth D. Dobson
Dartmouth Scholarship
The universal facial attractiveness (UFA) hypothesis proposes that some facial features are universally preferred because they are reliable signals of mate quality. The primary evidence for this hypothesis comes from cross-cultural studies of perceived attractiveness. However, these studies do not directly address patterns of morphological variation at the population level. An unanswered question is therefore: Are universally preferred facial phenotypes geographically invariant, as the UFA hypothesis implies? The purpose of our study is to evaluate this often overlooked aspect of the UFA hypothesis by examining patterns of geographic variation in chin shape. We collected symphyseal outlines from 180 recent human …
Humans And Dolphins: An Exploration Of Anthropocentrism In Applied Environmental Ethics, Thomas I. White
Humans And Dolphins: An Exploration Of Anthropocentrism In Applied Environmental Ethics, Thomas I. White
Management Faculty Works
This article argues that one of the reasons that the unethical character of much human-dolphin contact is not more apparent to ethicists is that discussion of central issues has been colored with unintentional species bias. This article points out weaknesses in the traditional approach to discussing topics that bear on the question of whether dolphins have moral standing. It demonstrates that discussions of the cognitive abilities of dolphins by Steven Wise and Alasdair MacIntyre are unintentionally but fundamentally anthropocentric-largely because the authors are not familiar with enough of the scientific literature about dolphins to draw the conclusions that they do.

Nursing Faculty Publications
For a majority of patients with advanced heart failure, there is a need for complementary, non-pharmacologic interventions that could be easily implemented by health care providers to provide palliative care. Three major pathologic pathways underlying heart failure symptoms have been identified: fluid overload, inflammation, and oxidative stress. Prior research has demonstrated that three nutrients-sodium, omega-3 fatty acids, and lycopene-can alter these pathologic pathways. Therefore, the purposes of this study are to test the effects of a 6-month nutrition intervention of dietary sodium reduction combined with supplementation of lycopene and omega-3 fatty acids on heart failure symptoms, health-related quality of life, …

Hardcastle, Adrian H. Taylor, Martin P. Bailey, Robert A. Harley, Martin S. Hagger
Peninsula Medical School
BACKGROUND: Intensive diet and physical activity interventions have been found to reduce cardiovascular disease (CVD) risk, but are resource intensive. The American Heart Association recently recommended motivational interviewing (MI) as an effective approach for low-intensity interventions to promote health-related outcomes such as weight loss. However, there is limited research evaluating the long-term effectiveness of MI-based interventions on health-related outcomes associated with CVD risk. The current research evaluated the effectiveness of a six-month low-intensity MI intervention in a UK primary-care setting in maintaining reductions in CVD risk factors at12 months post-intervention. METHODS: Primary-care patients were randomised to an intervention group that …

School of Nursing and Midwifery
BACKGROUND: Cervical screening uptake has increased as a result of occurrences of cervical cancer in TV 'soap operas' and in real life celebrities such as Jade Goody. Media analysis at the time of Jade Goody's death suggested the NHS did not take sufficient advantage of this opportunity to improve cervical screening rates. Google AdWords has been used to recruit and raise awareness of health but we were not aware of its use to supplement media events. METHODS: This was an opportunistic service evaluation to accompany a cervical cancer storyline in Eastenders (a TV 'soap opera'). We ran an AdWords campaign …

Marine food webs are the most important link between the global contaminant, methylmercury (MeHg), and human exposure through consumption of seafood. Warming temperatures may increase human exposure to MeHg, a potent neurotoxin, by increasing MeHg production as well as bioaccumulation and trophic transfer through marine food webs. Studies of the effects of temperature on MeHg bioaccumulation are rare and no study has specifically related temperature to MeHg fate by linking laboratory experiments with natural field manipulations in coastal ecosystems. We performed laboratory and field experiments on MeHg accumulation under varying temperature regimes using the killifish, Fundulus heteroclitus. Temperature treatments …

High-Throughput Phenotyping Of Uropathogenic E. Coli Isolates With Fourier Transform Infrared Spectroscopy., Haitham Alrabiah, Elon Correa, Mathew Upton, Royston Goodacre
School of Biomedical Sciences
Fourier transform infrared (FT-IR) spectroscopy is an established rapid whole-organism fingerprinting method that generates metabolic fingerprints from bacteria that reflect the phenotype of the microorganism under investigation. However, whilst FT-IR spectroscopy is fast (typically 10 s to 1 min per sample), the approaches for microbial sample preparation can be time consuming as plate culture or shake flasks are used for growth of the organism. We report a new approach that allows micro-cultivation of bacteria from low volumes (typically 200 μL) to be coupled with FT-IR spectroscopy. This approach is fast and easy to perform and gives equivalent data to the …

Environmental & Global Health Faculty Research
Intimate partner violence (IPV) may affect one to four million individuals per year in the United States, with women accounting for the majority of both reported and unreported cases. Dental professionals are in a unique position to identify many types of IPV because injuries to the head and neck may be indicators or predictors of IPV abuse. Fewer than half of dental programs surveyed have reported having IPV-specific curricula, and most dental students surveyed have reported having little experience or training to recognize IPV. Based on this information, this pilot study sought to assess the awareness and beliefs regarding IPV …

Adiponectin has antidiabetic properties, and patients with obesity, diabetes, and insulin resistance have low plasma adiponectin levels. However, although kidney disease is associated with insulin resistance, adiponectin is elevated in end-stage renal disease. Here we determine whether adipose tissue production of adiponectin is increased in renal disease in a case-control study of 36 patients with end-stage renal disease and 23 kidney donors. Blood and tissue samples were obtained at kidney transplantation and donation. The mean plasma adiponectin level was significantly increased to 15.6 mg/ml in cases compared with 8.4 mg/ml in controls. Plasma levels of the inflammatory adipokines tumor necrosis …

Department of Neurology Faculty Papers
In two recent reports, melanopsin gene variations were associated with seasonal affective disorder (SAD), and in changes in the timing of sleep and activity in healthy individuals. New studies have deepened our understanding of the retinohypothalamic tract, which translates environmental light received by the retina into neural signals sent to a set of nonvisual nuclei in the brain that are responsible for functions other than sight including circadian, neuroendocrine and neurobehavioral regulation. Because this pathway mediates seasonal changes in physiology, behavior, and mood, individual variations in the pathway may explain why approximately 1-2% of the North American population develops mood …

We report a novel noncontact diffuse correlation spectroscopy flow-oximeter for simultaneous quantification of relative changes in tissue blood flow (rBF) and oxygenation (Δ[oxygenation]). The noncontact probe was compared against a contact probe in tissue-like phantoms and forearm muscles (n = 10), and the dynamic trends in both rBF and Δ[oxygenation] were found to be highly correlated. However, the magnitudes of Δ[oxygenation] measured by the two probes were significantly different. Monte Carlo simulations and phantom experiments revealed that the arm curvature resulted in a significant underestimation (~-20%) for the noncontact measurements in Δ[ …

Implicitly Priming The Social Brain: Failure To Find Neural Effects, Katherine E. Powers, Todd F. Heatherton
Implicitly Priming The Social Brain: Failure To Find Neural Effects, Katherine E. Powers, Todd F. Heatherton
Dartmouth Scholarship
Humans have a fundamental need for social relationships. Rejection from social groups is especially detrimental, rendering the ability to detect threats to social relationships and respond in adaptive ways critical. Indeed, previous research has shown that experiencing social rejection alters the processing of subsequent social cues in a variety of socially affiliative and avoidant ways. Because social perception and cognition occurs spontaneously and automatically, detecting threats to social relationships may occur without conscious awareness or control. Here, we investigated the automaticity of social threat detection by examining how implicit primes affect neural responses to social stimuli. However, despite using a …

Primate evolution has been accompanied by complex reorganizations in brain anatomy and function. Little is known, however, about the relationship between anatomical and functional changes induced through primate evolution. Using functional magnetic resonance imaging, we assessed spatial and temporal correspondences of cortical networks in humans and monkeys. We provided evidence for topologically and functionally correspondent networks in sensory-motor and attention regions. More specifically, we revealed a possible monkey equivalent of the human ventral attention network. For other human networks, such as the language and the default-mode networks, we detected topological correspondent networks in the monkey, but with different functional signatures. …

The immense molecular diversity of neurons challenges our ability to understand the genetic and cellular etiology of neuropsychiatric disorders. Leveraging knowledge from neurobiology may help parse the genetic complexity: identifying genes important for a circuit that mediates a particular symptom of a disease may help identify polymorphisms that contribute to risk for the disease as a whole. The serotonergic system has long been suspected in disorders that have symptoms of repetitive behaviors and resistance to change, including autism. We generated a bacTRAP mouse line to permit translational profiling of serotonergic neurons. From this, we identified several thousand serotonergic-cell expressed transcripts, …

Few physiatrists today would appreciate Dr. Robert L. Bennett’s contributions to our specialty, since he most commonly was associated with poliomyelitis, a cured disease for over a half century. Less are aware of the pioneering fusion of physical medicine in 1941 by Krusen’s first resident with the independent living environment of the Georgia Warm Spring Foundation (GWSF) created by a USA president. Bennett recognized polio/GWSF as the workshop and laboratory for showcasing the new specialty of Physical Medicine and Rehabilitation (PMR). He taught us that accurate muscle testing determined the plan of muscle reeducation, which led to functional training with …
