Causes, Consequences, And Treatment Of Osteoporosis In Men, Jameela Banu

Health & Biomedical Sciences Faculty Publications

Men undergo gradual bone loss with aging, resulting in fragile bones. It is estimated that one in five men will suffer an osteoporotic fracture during their lifetime. The prognosis for men after a hip fracture is very grim. A major cause is reduction of free testosterone. Many other factors result in secondary osteoporosis, including treatment for other diseases such as cancer and diabetes. Patients should be screened not only for bone density but also assessed for their nutritional status, physical activity, and drug intake. Therapy should be chosen based on the type of osteoporosis. Available therapies include testosterone replacement, bisphosphonates, …

Amyloid Β Peptides Modify The Expression Of Antioxidant Repair Enzymes And A Potassium Channel In The Septohippocampal System, Jorge Duran-Gonzalez, Edna D. Michi, Brisa Elorza, Miriam G. Perez-Cordova, Luis F. Pacheco Otalora, Ahmed Touhami, Pamela Paulson, George Perry, Ian V. Murray, Luis V. Colom

Health & Biomedical Sciences Faculty Publications

Alzheimer's disease (AD) is a progressive, neurodegenerative brain disorder characterized by extracellular accumulations of amyloid β (Aβ) peptides, intracellular accumulation of abnormal proteins, and early loss of basal forebrain neurons. Recent studies have indicated that the conformation of Aβ is crucial for neuronal toxicity, with intermediate misfolded forms such as oligomers being more toxic than the final fibrillar forms. Our previous work shows that Aβ blocks the potassium (K(+)) currents IM and IA in septal neurons, increasing firing rates, diminishing rhythmicity and firing coherence. Evidence also suggests that oxidative stress (OS) plays a role in AD pathogenesis. Thus we wished …

Horner's Syndrome Secondary To Neuroblastoma, Roberto A. Cruz, T. K. Tran, Nicky R. Holdeman, Christian Cajavilca, Rosa A. Tang

School of Medicine Publications

Horner’s syndrome is classically characterized by a triad of miosis, partial ptosis and anhidrosis. The etiology is due to an interruption in the sympathetic innervation to the eye. A prompt diagnosis is crucial, given that Horner’s syndrome could be a manifestation of a life-threatening condition. A thorough case history and clinical evaluation must be employed to arrive at the diagnosis. An important means for confirming Horner’s syndrome is pharmacological testing, which is also used to localize the level where the sympathetic chain is compromised. Following the diagnosis and localization of the lesion, an algorithm should be followed to determine the …

Gsx2 Controls Region-Specific Activation Of Neural Stem Cells And Injury-Induced Neurogenesis In The Adult Subventricular Zone, Alejandro Lopez-Juarez, Jennifer Howard, Kristy Ullom, Lindsey Howard, Andrew Grande

Health & Biomedical Sciences Faculty Publications

Neural stem cells (NSCs) reside in widespread regions along the lateral ventricle and generate diverse olfactory bulb (OB) interneuron subtypes in the adult mouse brain. Molecular mechanisms underlying their regional diversity, however, are not well understood. Here we show that the homeodomain transcription factor Gsx2 plays a crucial role in the region-specific control of adult NSCs in both persistent and injury-induced neurogenesis. In the intact brain, Gsx2 is expressed in a regionally restricted subset of NSCs and promotes the activation and lineage progression of stem cells, thereby controlling the production of selective OB neuron subtypes. Moreover, Gsx2 is ectopically induced …

Memantine Protects Cholinergic And Glutamatergic Septal Neurons From Aβ1-40-Induced Toxicity, Luis V. Colom, María Teresa Castañeda Licón, D. Aleman, Ahmed Touhami

Health & Biomedical Sciences Faculty Publications

The medial septal region (medial septum and diagonal band of Broca, MS/DB) controls hippocampal excitability and synaptic plasticity. MS/DB cholinergic neurons degenerate early in Alzheimer’s disease (AD). The presence of MS/DB glutamatergic neurons that project to the hippocampus and are vulnerable to Aβ suggests that excitotoxicity plays a role in AD septal degeneration and hippocampal dysfunction. To demonstrate the presence of excitotoxicity in Aβinduced septal damage, we compared rats injected with Aβ1–40 into the MS/DB with animals treated with memantine prior, during and after Aβ1–40 injections. Controls were injected with phosphate buffered saline (PBS). MS/DB cholinergic, glutamatergic and GABAergic neurons …

Global Prefrontal And Fronto-Amygdala Dysconnectivity In Bipolar I Disorder With Psychosis History, Alan Anticevic, Margaret S. Brumbaugh, Anderson M. Winkler, Lauren E. Lombardo, Jennifer Barrett, Phillip R. Corlett, Hedy Kober, June Gruber, Grega Repovs, Michael W. Cole

School of Medicine Publications

BACKGROUND: Pathophysiological models of bipolar disorder postulate that mood dysregulation arises from fronto-limbic dysfunction, marked by reduced prefrontal cortex (PFC) inhibitory control. This might occur due to both disruptions within PFC networks and abnormal inhibition over subcortical structures involved in emotional processing. However, no study has examined global PFC dysconnectivity in bipolar disorder and tested whether regions with within-PFC dysconnectivity also exhibit fronto-limbic connectivity deficits. Furthermore, no study has investigated whether such connectivity disruptions differ for bipolar patients with psychosis history, who might exhibit a more severe clinical course. METHODS: We collected resting-state functional magnetic resonance imaging at 3T in …

School of Medicine Publications

Background

Elevated rate of aging-related biological and functional decline, termed “accelerated aging,” is reported in patients with schizophrenia (SCZ) and major depressive disorder (MDD). We used diffusion tensor imaging derived fractional anisotropy (FA) as a biomarker of aging-related decline in white matter (WM) integrity to test the hypotheses of accelerated aging in SCZ and MDD.

Methods

The SCZ cohort comprised 58 SCZ patients and 60 controls (aged 20–60 years). The MDD cohort comprised 136 MDD patients and 351 controls (aged 20–79 years). The main outcome measures were the diagnosis-by-age interaction on whole-brain-averaged WM FA values and FA values from 12 …

Conceptualizing The Use Of Cognitive Interventions Among Persons With Intellectual Disabilities Who Experience Depression, Abdoulaye Diallo, Shawn P. Saladin, Darlene A.G. Groomes, Jerome Fischer, Sandra Hansmann

School of Rehabilitation Services & Counseling Faculty Publications

Depression can affect the lives of all persons and can have especially profound implications on those with cognitive limitations; however, depression need not be an insurmountable roadblock to employment for persons with intellectual disabilities. Cognitive interventions - such as life story approach, socio-cognitive, and rational emotive behavior therapy-can be effective for litigating problems with depression among those with cognitive limitation including employment-related barriers due to depression. This article reviews how counselors can use cognitive interventions' behavioral and cognitive components to assist those with intellectual disabilities with depression.

Is Bisphenol-A Exposure During Pregnancy Associated With Blood Glucose Levels Or Diagnosis Of Gestational Diabetes?, Candace A. Robledo, Jennifer D. Peck, Julie A. Stoner, Hélène Carabin, Linda Cowan, Holger M. Koch, Jean R. Goodman

School of Medicine Publications

Recent epidemiological studies indicate bisphenol A (BPA), an estrogenic chemical used in production of epoxy, polycarbonate, and plastic may increase risk of insulin resistance and type 2 diabetes. Exposure to BPA during pregnancy may contribute to development of gestational diabetes mellitus (GDM), a precursor to type 2 diabetes in women. This pilot study examined the association between BPA exposure, fasting blood glucose levels (FBG), and GDM diagnosis during pregnancy. Banked urine samples from 22 cases of GDM and 72 controls were analyzed for total (free BPA + conjugates) urinary BPA concentrations (μg/L). FBG levels (mg/dl) were obtained from 1-h 50-g …

Environmental Impact On Direct Neuronal Reprogramming In Vivo In The Adult Brain, Andrew Grande, Kyoko Sumiyoshi, Alejandro Lopez-Juarez, Jennifer Howard, Bhuvaneswari Sakthivel, Bruce Aronow, Kenneth Campbell

Health & Biomedical Sciences Faculty Publications

Direct reprogramming of non-neuronal cells to generate new neurons is a promising approach to repair damaged brains. Impact of the in vivo environment on neuronal reprogramming, however, is poorly understood. Here we show that regional differences and injury conditions have significant influence on the efficacy of reprogramming and subsequent survival of newly generated neurons in the adult rodent brain. A combination of local exposure to growth factors and retrovirus-mediated overexpression of the neurogenic transcription factor Neurogenin2 (Neurog2) can induce new neurons from non-neuronal cells in the adult neocortex and striatum where neuronal turnover is otherwise very limited. These two regions …

Bcl9 And C9orf5 Are Associated With Negative Symptoms In Schizophrenia: Meta-Analysis Of Two Genome-Wide Association Studies, Chun Xu, Nagesh Aragam, Xia Li, Erika Cynthia Villa, Liang Wang, David Briones, Brenda Bin Su, Michael A. Escamilla, Kesheng Wang

Health & Biomedical Sciences Faculty Publications

Schizophrenia is a chronic and debilitating psychiatric condition affecting slightly more than 1% of the population worldwide and it is a multifactorial disorder with a high degree of heritability (80%) based on family and twin studies. Increasing lines of evidence suggest intermediate phenotypes/endophenotypes are more associated with causes of the disease and are less genetically complex than the broader disease spectrum. Negative symptoms in schizophrenia are attractive intermediate phenotypes based on their clinical and treatment response features. Therefore, our objective was to identify genetic variants underlying the negative symptoms of schizophrenia by analyzing two genome-wide association (GWA) data sets consisting …

The Two-Phase Arterial Blood Flow With Or Without A Catheter And In The Presence Of A Single Or Multi Stenosis, Ani E. Garcia, Daniel N. Riahi

School of Mathematical & Statistical Sciences Faculty Publications

We consider the problem of blood flow in an artery with or without a catheter and in the presence of single or multi stenosis whose shape is based on the available experimental data for the stenosis in a human’s artery. The presence of stenosis in the artery, which locally narrows portion of the artery, can be a result of fatty materials such as cholesterol in the blood. The use of catheter is important as a standard tool for diagnosis and treatment in patience whose blood flow passage in the artery is affected adversely by the presence of the stenosis within …

Proteomic Identification Of Dengue Virus Binding Proteins In Aedes Aegypti Mosquitoes And Aedes Albopictus Cells, Maria De Lourdes Muñoz, Gustavo Limón-Camacho, Rosalinda Tovar, Alvaro Diaz-Badillo, Guillermo Mendoza-Hernández, William C. Black

School of Medicine Publications

The main vector of dengue in America is the mosquito Aedes aegypti, which is infected by dengue virus (DENV) through receptors of midgut epithelial cells. The envelope protein (E) of dengue virus binds to receptors present on the host cells through its domain III that has been primarily recognized to bind cell receptors. In order to identify potential receptors, proteins from mosquito midgut tissue and C6/36 cells were purified by affinity using columns with the recombinant E protein domain III (rE-DIII) or DENV particles bound covalently to Sepharose 4B to compare and evaluate their performance to bind proteins including …

Identification Of Pleiotropic Genetic Effects On Obesity And Brain Anatomy, Joanne E. Curran, D Reese Mckay, Anderson M. Winkler, Rene L. Olvera, Thomas D. Dyer, Peter T. Fox, Laura Almasy, Ravi Duggirala, John Blangero, David C. Glahn

School of Medicine Publications

Background/aims: Obesity is a major contributor to the global burden of chronic disease and disability, though current knowledge of causal biologic underpinnings is lacking. Through the regulation of energy homeostasis and interactions with adiposity and gut signals, the brain is thought to play a significant role in the development of this disorder. While neuroanatomical variation has been associated with obesity, it is unclear if this relationship is influenced by common genetic mechanisms. In this study, we sought genetic components that influence both brain anatomy and body mass index (BMI) to provide further insight into the role of the brain in …

Short-Term Exercise Training Improves Insulin Sensitivity But Does Not Inhibit Inflammatory Pathways In Immune Cells From Insulin-Resistant Subjects, Sara M. Reyna, Puntip Tantiwong, Eugenio Cersosimo, Ralph A. Defronzo, Apiradee Sriwijitkamol, Nicolas Musi

School of Medicine Publications

Background. Exercise has an anti-inflammatory effect against, and immune cells play critical roles in the development, of insulin resistance and atherosclerotic vascular disease (AVD). Thus, the goal of this study was to determine whether exercise improves insulin sensitivity in insulin-resistant subjects by downregulating proinflammatory signaling in immune cells.

Methods. Seventeen lean, 8 obese nondiabetic, and 11 obese type 2 diabetic individuals underwent an aerobic exercise program for 15 days and an insulin clamp before and after exercise. Peripheral mononuclear cells (PMNC) were obtained for determination of Toll-like receptor (TLR) 2 and 4 protein content and mitogen-activated protein kinase phosphorylation.

Tuning Of Alternative Splicing - Switch From Proto-Oncogene To Tumor Suppressor, Aleksandra Shchelkunova, Boris Ermolinsky, Meghan Boyle, Ivan Mendez, Michael Lehker, Karen S. Martirosyan, Alexander V. Kazanksy

Health & Biomedical Sciences Faculty Publications

STAT5B, a specific member of the STAT family, is intimately associated with prostate tumor progression. While the full form of STAT5B is thought to promote tumor progression, a naturally occurring truncated isoform acts as a tumor suppressor. We previously demonstrated that truncated STAT5 is generated by insertion of an alternatively spliced exon and results in the introduction of an early termination codon. Present approaches targeting STAT proteins based on inhibition of functional domains of STAT's, such as DNA-binding, cooperative binding (protein-protein interaction), dimerization and phosphorylation will halt the action of the entire gene, both the proto-oncogenic and tumor suppressor functions …

Laing, Beverly Smulevitz, Kristina Vatcheva, Anne R. Rentfro, David D. Mcpherson, Susan P. Fisher-Hoch, Joseph B. Mccormick

School of Mathematical & Statistical Sciences Faculty Publications

Background: Framingham risk scores (FRS) were validated in a mostly Caucasian population. Evaluation of subclinical atherosclerosis by carotid ultrasound may improve ascertainment of risk in nonwhite populations. This study aimed to evaluate carotid intima-media thickness (cIMT) and carotid plaquing among Mexican Americans, and to correlate these markers with coronary risk factors and the FRS.

Methods/results: Participants (n = 141) were drawn from the Cameron County Hispanic Cohort. Carotid artery ultrasound was performed and cIMT measured. Carotid plaque was defined as areas of thickening >50% of the thickness of the surrounding walls. Mean age was 53.1 ± 11.7 years (73.8% female). …

Determining Cognitive And Non-Cognitive Predictors Of Success On The National Physical Therapy Examination, Carolyn Galleher, Peter J. Rundquist, David B. Barker, Wen-Pin Chang

Occupational Therapy Faculty Publications

Background and Purpose: A variety of admission criteria have been utilized to assist in the selection of viable candidates in physical therapy programs. These criteria include cognitive measurements such as grade point average (GPA) and standardized test scores. However, only a few studies correlated these cognitive measurements to predicting success on the National Physical Therapy Examination (NPTE). The purpose of this study was to examine the performance of entry-level doctoral physical therapy (DPT) students on prior cognitive measurements and correlate it to passing on the first attempt of the NPTE. This study also aimed to determine if two inventory surveys …

School of Medicine Publications

Background: Lipopolysaccharides (LPSs) up-regulate proinflammatory cytokines in macrophages, partly through a NF-κB-dependent process.

Results: Blocking neddylation, which helps regulate NF-κB, represses LPS-induced up-regulation of proinflammatory cytokines.

Conclusion: Neddylation plays a role in the up-regulation of NF-κB-regulated proinflammatory cytokines produced by macrophages in response to LPS.

Significance: Inhibition of neddylation represents a novel and effective method for the prevention of LPS-induced proinflammatory cytokines.

Genetic Architecture Of Declarative Memory: Implications For Complex Illnesses, Carrie E. Bearden, Katherine H. Karlsgodt, Peter Bachman, Theo G. Van Erp, Anderson M. Winkler, David C. Glahn

School of Medicine Publications

Why do memory abilities vary so greatly across individuals and cognitive domains? Although memory functions are highly heritable, what exactly is being genetically transmitted? Here we review evidence for the contribution of both common and partially independent inheritance of distinct aspects of memory function. We begin by discussing the assessment of long-term memory and its underlying neural and molecular basis. We then consider evidence for both specialist and generalist genes underlying individual variability in memory, indicating that carving memory into distinct subcomponents may yield important information regarding its genetic architecture. And finally we review evidence from both complex and single-gene …

To better understand dynamic factors related to employment over time this study analyzed the changing demographics of consumers with spinal cord injury (SCI) who received state vocational rehabilitation services between 2004 and 2008. The entire population of 23,135 individuals with an SCI who closed in status 26 (employment outcome) or 28 (no employment outcome) between 2004 and 2008 were included in the study. Several changes were observed. There was a disproportionate decline in the number of consumers with …

Association Of Differential Gene Expression With Imatinib Mesylate And Omacetaxine Mepesuccinate Toxicity In Lymphoblastoid Cell Lines, Hemant Kulkarni, Harald H. H. Goring, Vincent P. Diego, Shelley A. Cole, Ken R. Walder, Greg R. Collier, John Blangero, Melanie A. Carless

School of Medicine Publications

Background: Imatinib mesylate is currently the drug of choice to treat chronic myeloid leukemia. However, patient resistance and cytotoxicity make secondary lines of treatment, such as omacetaxine mepesuccinate, a necessity. Given that drug cytotoxicity represents a major problem during treatment, it is essential to understand the biological pathways affected to better predict poor drug response and prioritize a treatment regime.

Methods: We conducted cell viability and gene expression assays to determine heritability and gene expression changes associated with imatinib and omacetaxine treatment of 55 non-cancerous lymphoblastoid cell lines, derived from 17 pedigrees. In total, 48,803 transcripts derived from Illumina …
