Effects Of Yoga On Thalamic Gamma-Aminobutyric Acid, Mood And Depression: Analysis Of Two Randomized Controlled Trials, Chris C. Streeter, Patricia L. Gerbarg, Greylin H. Nielsen, Richard P. Brown, J Eric Jensen, Marisa M. Silveri

NYMC Faculty Publications

Objective: The Vagal-Gamma-Aminobutyric Acid (GABA) theory proposes that some yoga postures and breathing practices exert their effects through stimulation of vagal nerves (parasympathetic system) with associated brain GABA increases. To evaluate this theory, we compared results from a 12-week randomized controlled trial (RCT) of yoga in participants with Major Depressive Disorder (MDD) with those of a similar RCT in healthy control participants (HC).

Methods: In an RCT, magnetic resonance spectroscopy (MRS) and mood measures were acquired in subjects with MDD (n=15) prior to and following a 12-week yoga intervention. The same measures were obtained in the HC (n=17) group. In …

Breathing New Life: Investigating Ways To Improve The Mental Health Of People Living With Chronic Obstructive Pulmonary Disease In Western Australia, Tina Phan

Theses: Doctorates and Masters

Anxiety and depression are common comorbidities in people with chronic obstructive pulmonary disease (COPD), contributing to greater morbidity and mortality in an already vulnerable population. Despite the prevalence, few recommendations exist in global management guidelines for the detection and treatment of these comorbidities, reflecting the limited literature available on effective strategies for dealing with mental health issues in COPD populations. There is promising evidence that cognitive behavioural therapy (CBT) improves mental health outcomes in people with COPD. However, investigational studies have commonly reported participants’ lack of transport, lack of time and illness as barriers to recruitment and successful completion. This …

To improve early stage melanoma detection, the development of a highly sensitive diagnostic test is of utmost importance. Here we aimed to identify antibodies to a panel of tumour associated antigens that can differentiate primary melanoma patients and healthy individuals. A total of 245 sera from primary melanoma patients and healthy volunteers were screened against a high-throughput microarray platform containing 1627 functional proteins. Following rigorous statistical analysis, we identified a combination of 10 autoantibody biomarkers …

Evaluation Of A Drug Delivery System Based On Cyclodextrins For Cancer Therapy, Caroline Mendes

Doctoral

Due to the side-effects caused by regular chemotherapy, the development of drug delivery systems that can specifically target cancer cells and deliver the therapeutic dose is required. In this study, a folate-derivative of β-cyclodextrin has been studied as a vehicle for targeting folate receptors (FR) and delivering the chemotherapeutic drug methotrexate (MTX). FRs can be considered key cell membrane targets since they are commonly over-expressed in cancer cells and play an important role in cancer development and progression. Cyclodextrins (CDs) are cyclic oligosaccharides with a unique structure that allows them to form inclusion complexes with guest molecules, increasing their aqueous …

Evaluation Of Extracellular Matrix Composition And Rheology As Determinants Of Growth, Invasion, And Response To Photodynamic Therapy In 3d Cell Culture Models Of Pancreatic Ductal Adenocarcinoma, Gwendolyn M. Cramer

Graduate Doctoral Dissertations

Pancreatic ductal adenocarcinoma (PDAC) is a notoriously lethal disease characterized by prominent stromal involvement, which plays complex roles in regulating tumor growth and therapeutic response. The extracellular matrix (ECM)-rich stroma has been implicated as a barrier to drug penetration, although stromal depletion strategies have had mixed clinical success. It remains less clear how biophysical interactions with the ECM regulate invasive progression and susceptibilities to specific therapies. Here, an integrative approach combining 3D cell culture and quantitative imaging techniques is used to evaluate invasive behavior and motility as determinants of response to classical chemotherapy and photodynamic therapy (PDT), in which light …

Efficacy Of Topical Estradiol Compared To Topical Glycolic Acid For Skin Aging Treatment In Postmenopausal Women, Shannaz Nada Yusharyahya, Marsha Bianti

Journal of General - Procedural Dermatology and Venereology Indonesia

Skin aging is a complex biological process in human being, as a result from intrinsic factors (genetic, hormonal, metabolism) and extrinsic factors (UV exposure, pollution, smoking, life style). In postmenopausal women, physiologically, the amount of estrogen are decreased, causing deterioration of their skin’s appearance.

Along with the changes that occur, skin care require more attention. A holistic approach can increase epidermal thickness, therefore, reducing the depth of wrinkles, as well as improving skin texture and moisture. There are various treatments available to improve skin appearance due to aging.

This EBCR is aimed to compare the efficacy of topical estradiol and …

Publications and Research

Gay, bisexual, and other men who have sex with men (GBM) are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP) in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906) would prefer to get PrEP-related care from a primary care provider (PCP) compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i.e., HB-PrEP), defined to participants as conducting …

Tfpiα Interacts With Fva And Fxa To Inhibit Prothrombinase During The Initiation Of Coagulation, Jeremy P. Wood, Helle H. Petersen, Bingke Yu, Xiaoai Wu, Ida Hilden, Alan E. Mast

Gill Heart & Vascular Institute Faculty Publications

Tissue factor pathway inhibitor α (TFPIα) inhibits prothrombinase, the thrombin-generating complex of factor Xa (FXa) and factor Va (FVa), during the initiation of coagulation. This inhibition requires binding of a conserved basic region within TFPIα to a conserved acidic region in FXa-activated and platelet-released FVa. In this study, the contribution of interactions between TFPIα and the FXa active site and FVa heavy chain to prothrombinase inhibition were examined to further define the inhibitory biochemistry. Removal of FXa active site binding by mutation or by deletion of the second Kunitz domain (K2) of TFPIα produced 17- or 34-fold weaker prothrombinase inhibition, …

ETSU Faculty Works

LIMD1 (LIM domain-containing protein 1) is considered as a tumor suppressor, being deregulated in many cancers to include hematological malignancies; however, very little is known about the underlying mechanisms of its deregulation and its roles in carcinogenesis. Epstein-Barr Virus (EBV) is associated with a panel of malignancies of lymphocytic and epithelial origin. Using high throughput expression profiling, we have previously identified LIMD1 as a common marker associated with the oncogenic transcription factor IRF4 in EBV-related lymphomas and other hematological malignancies. In this study, we have identified potential conserved IRF4- and NFκB-binding motifs in the LIMD1 gene promoter, and both are …

Histomorphology Of Trauma In Charred And Decomposed Remains, Mariya Bezugly

Student Theses

Decomposition and burning of human remains are frequently encountered in forensic cases, and pose a challenge at determining an accurate cause of death. At autopsy, macroscopic techniques fail to reach beyond superficial layers of degraded tissue to identify wound morphology that characterizes blunt-force gunshot, and sharp-force trauma. The postmortem damage imparted on tissue with pre-existing injuries, obstructs the external features of trauma. Exploring beyond charred and decayed superficial tissue, histo-morphological patterns of injury are still identifiable as shown in this thesis. With detailed observation to the pattern of tissue disruption- an understanding of the type of trauma imposed can be …

Snail Determines The Therapeutic Response To Mtor Kinase Inhibitors By Transcriptional Repression Of 4e-Bp1, Jun Wang, Qing Ye, Yanan Cao, Yubin Guo, Xiuping Huang, Wenting Mi, Side Liu, Chi Wang, Hsin-Sheng Yang, Binhua P. Zhou, B. Mark Evers, Qing-Bai She

Markey Cancer Center Faculty Publications

Loss of 4E-BP1 expression has been linked to cancer progression and resistance to mTOR inhibitors, but the mechanism underlying 4E-BP1 downregulation in tumors remains unclear. Here we identify Snail as a strong transcriptional repressor of 4E-BP1. We find that 4E-BP1 expression inversely correlates with Snail level in cancer cell lines and clinical specimens. Snail binds to three E-boxes present in the human 4E-BP1 promoter to repress transcription of 4E-BP1. Ectopic expression of Snail in cancer cell lines lacking Snail profoundly represses 4E-BP1 expression, promotes cap-dependent translation in polysomes, and reduces the anti-proliferative effect of mTOR kinase inhibitors. Conversely, genetic …
