The Mozambique Eyecare Project: Implementing A Model That Addresses Uncorrected Refractive Error In Lusophone Africa., Stephen Thompson, Diane Wallace

Conference Papers

BACKGROUND

Optometric education and resources are drastically deficient in most of Africa, more so in Lusophone Africa where the problem is compounded by language barriers which isolate these countries from related developments in Africa and/or the developed world.

The Mozambique Eyecare Programme is a multi-partner collaboration between The International Centre for Eyecare Education (ICEE), Universidade Lúrio in Mozambique, Technological University Dublin, and the University of Ulster in Ireland, designed to address the need for optometric education in Lusophone Africa.

AIM

This paper aims to document the current situation with regards to human resource development in eyecare in Mozambique and offer …

Safety, Tolerability, And Efficacy Of Fixed Combination Therapy With Dorzolamide Hydrochloride 2% And Timolol Maleate 05% In Glaucoma And Ocular Hypertension, Nicholas P Bell, José L Ramos, Robert M Feldman

Faculty, Staff and Student Publications

Glaucoma is a collection of diseases characterized by multifactorial progressive changes leading to visual field loss and optic neuropathy most frequently due to elevated intraocular pressure (IOP). The goal of treatment is the lowering of the IOP to prevent additional optic nerve damage. Treatment usually begins with topical pharmacological agents as monotherapy, progresses to combination therapy with agents from up to 4 different classes of IOP-lowering medications, and then proceeds to laser or incisional surgical modalities for refractory cases. The fixed combination therapy with the carbonic anhydrase inhibitor dorzolamide hydrochloride 2% and the beta blocker timolol maleate 0.5% is now …

Solar Simulated Radiation Induced Cell Death Depends On Spectral Distribution And Irradiance But Not Output Delivery, Alanna Maguire, Fiona Lyng, James Walsh

Articles

Photo biological investigations are dependent on calibration and characterisation to determine the relevance of an artificial irradiator to the study at hand. The importance of this has been voiced in the literature. However, the importance of output delivery is relatively unknown. The biological relevance of a high energy, rapidly pulsing solar simulator was investigated using the clonogenic assay and was found to be reciprocity law compliant despite an exaggerated UV irradiance in excess of 1600 Wm-2 delivered per pulse. In fact, it was found to be the least cytotoxic irradiator compared to a second solar simulator and a UVB fluorescent …

Application Of Magnetic Resonance Imaging To Understanding The Pathogenesis Of The X-Linked Leukodystrophy Pelizaeus-Merzbacher Disease, Jeremy Jerome Laukka

Wayne State University Dissertations

Myelin is a multilamellar membrane structure surrounding axons in both the CNS and PNS that facilitates nerve conduction. In the CNS, myelin is synthesized by oligodendrocytes, while in the PNS, myelin is synthesized by Schwann cells. In the CNS, Proteolipid protein 1 (PLP1), an integral membrane protein, is the major protein component of myelin, constituting ~50% of myelin protein. Mutations of the PLP1 gene in man cause a spectrum of neurological disease, ranging from the severe Pelizaeus-Merzbacher disease (PMD), that typically begins during infancy with nystagmus, seizures and hypotonia and evolves into spastic quadriparesis, cognitive impairment and ataxia, to ¡¥pure¡¦ …

The Effects Of Pet Ownership On Physical Well-Being In Older Adults, Tami Pohnert

Theses and Dissertations

A large percentage of Americans own pets which may impact their health. This study examines pet ownership’s effect on well being in older adults looking at race/ethnicity. A sample of 6,565 older adults (>60) was selected from the Third National Health and Nutrition Survey. Pet owners comprised 28.3% of the sample. The theories of symbolic interaction and social integration were used to examine pet ownership’s effect on physical components of well-being. The descriptive results showed statistically significant differences in age, education, income, and marital status between pet owners and non-pet owners. Pet owners were younger, more educate, higher income …

Application Of X-Ray Diffraction To Material Analysis And Medical Imaging, Wei Zhou

Legacy Theses & Dissertations (2009 - 2024)

Powder diffraction is commonly used to determine the structures of both inorganic and organic materials. The angle and intensity of the diffraction (also called coherent scatter) peak depends on the nanostructure of the material. When no x-ray optic is used, the peak width broadens, and hence the resolution worsens, as the sample area is increased. However, a small sample area gives low diffracted signal intensity, particularly for thin films and for organic materials, which have low diffraction cross sections. X-ray optics can be used in x-ray powder diffraction to increase the diffraction intensity, thus decreasing exposure times. For a small …

Chlorella Viruses Encode Most, If Not All, Of The Machinery To Glycosylate Their Glycoproteins Independent Of The Endoplasmic Reticulum And Golgi, James L. Van Etten, James Gurnon, Giane M. Yanai-Balser, David Dunigan, Michael V. Graves

Nebraska Center for Virology: Faculty Publications

In contrast to all other viruses that use the host machinery located in the endoplasmic reticulum and Golgi to glycosylate their glycoproteins, the large dsDNA-containing chlorella viruses encode most, if not all, of the components to glycosylate their major capsid proteins. Furthermore, all experimental results indicate that glycosylation occurs independent of the endoplasmic reticulum and Golgi. (Review article)

Apoptosis Initiation And Angiogenesis Inhibition: Melanoma Targets For Nanosecond Pulsed Electric Fields, Xinhua Chen, Juergen F. Kolb, R. James Swanson, Karl H. Schoenbach, Stephen J. Beebe

Bioelectrics Publications

Many effective anti-cancer strategies target apoptosis and angiogenesis mechanisms. Applications of non-ionizing, nanosecond pulsed electric fields (nsPEFs) induce apoptosis in vitro and eliminate cancer in vivo; however in vivo mechanisms require closer analysis. These studies investigate nsPEF-induced apoptosis and anti-angiogenesis examined by fluorescent microscopy, immunoblots, and morphology. Six hours after treatment with one hundred 300 ns pulses at 40 kV/cm, cells transiently expressed active caspases indicating that caspase-mediated mechanisms. Three hours after treatment transient peaks in Histone 2AX phosphorylation coincided with terminal deoxynucleotidyl transferase dUTP nick end labeling positive cells and pyknotic nuclei, suggesting caspase-independent mechanisms on nuclei/DNA.

Doxazosin Induces Apoptosis In Pten–Positive Androgen-Independent Pc Cells Via Inhibition Of Akt Activation, Hanna M Romanska, Maciej Salagierski, Rachel Bruton, P D Abel, Marek Sosnowski, El Nasir Lalani

Department of Pathology and Laboratory Medicine

Doxazosin, a selective α1-adrenoreceptor antagonist widely used in the management of benign prostatic hyperplasia (BPH), has been shown to induce apoptosis in androgen-independent (AI) and PTEN (phosphatases and tensin homolog)-negative prostate cancer (PC) cells. The objective of this study was to assess the effects of doxazosin on the growth of PC cells with a functional PTEN/PI3K/Akt pathway in relation to cell androgen sensitivity and Bcl-2 expression. Material and methods. The DU145 cell line and two derivatives: 1) DKC9 [DU145 (Bcl2 +/+)] and 2) DAR19 [DU145 (AR+/+)] were used. The effect of doxazosin on i) cell proliferation and ii) Akt phosphorylation …

I-Kappa-Kinase-2 (Ikk-2) Inhibition Potentiates Vincristine Cytotoxicity In Non-Hodgkin's Lymphoma, Ayad Al-Katib, Alan A. Arnold, Amro Aboukameel, Angela Sosin, Peter Smith, Anwar N. Mohamed, Frances W. Beck, Ramzi M. Mohammad

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

IKK-2 is an important regulator of the nuclear factor-κB (NF-κB) which has been implicated in survival, proliferation and apoptosis resistance of lymphoma cells. In this study, we investigated whether inhibition of IKK-2 impacts cell growth or cytotoxicity of selected conventional chemotherapeutic agents in non-Hodgkin's lymphoma.

Two established model systems were used; Follicular (WSU-FSCCL) and Diffuse Large Cell (WSU-DLCL2) Lymphoma, both of which constitutively express p-IκB. A novel, selective small molecule inhibitor of IKK-2, ML120B (N-[6-chloro-7-methoxy-9H-β-carbolin-8-yl]-2-methylnicotinamide) was used to perturb NF-κB in lymphoma cells. The growth inhibitory effect of ML120B (M) alone and in combination with cyclophosphamide monohydrate (C), …

The Wnt/Β-Catenin Pathway Regulates Growth And Maintenance Of Colonospheres, Shailender S. Kanwar, Yingjie Yu, Jyoti Nautiyal, Bhaumik B. Patel, Adhip Pn Majumdar

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Recent evidence suggests that epithelial cancers, including colorectal cancer are driven by a small sub-population of self-renewing, multi-potent cells termed cancer stem cells (CSCs) which are thought to be responsible for recurrence of cancer. One of the characteristics of CSCs is their ability to form floating spheroids under anchorage-independent conditions in a serum-free defined media. The current investigation was undertaken to examine the role of Wnt/β-catenin pathway in regulating the growth and maintenance of colonospheres. Human colon cancer cells HCT-116 (p53 wild type; K-ras mutant), HCT-116 (p53 null; K-ras mutant) and HT-29 (p53 mutant) were used.

A Novel Mechanism Of Cell Growth Regulation By Cell Cycle And Apoptosis Regulatory Protein (Carp)-1, Yan Jiang, Vineshkumar T. Puliyappadamba, Liyue Zhang, Wenjuan Wu, Anil Wali, Michael B. Yaffe, Joseph A. Fontana, Arun K. Rishi

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

CARP-1/CCAR1, a perinuclear phospho-protein, regulates signaling by adriamycin, steroids, or growth factors. However, intracellular events that regulate CARP-1-dependent cell growth are not fully understood.

Results

Here we investigated whether CARP-1 is involved in signaling induced by the protein kinase A inhibitor H89. Treatments of human breast cancer cells with H89 resulted in apoptosis that involved enhanced CARP-1 threonine phosphorylation and expression. Depletion of CARP-1, on the other hand, abrogates apoptosis induced by H89. CARP-1 binds with signal transducer TAZ and over-expression of TAZ inhibits apoptosis by CARP-1. CARP-1 (651-759) interacts with a novel, N-terminal epitope of TAZ. H89 …

Acute Subarachnoid Hemorrhage And Cardiac Abnormalities: Takotsubo Cardiomyopathy Or Neurogenic Stunned Myocardium? A Case Report, C Franco, B Khaled, L Afonso, M Raufi

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Cardiac abnormalities can be seen with subarachnoid hemorrhage. To date, there have been isolated case reports of transient left ventricular apical ballooning cardiomyopathy, also known as Takotsubo cardiomyopathy in patients suffering from subarachnoid hemorrhage.

Case presentation

An adult female was brought to the emergency department with somnolence. A 3 × 3 mm ruptured basilar aneurysm was found and successfully embolized. Two days after the patient developed acute heart failure. Troponin-I was elevated to 4.2 (normal <0.4). On ECG, new symmetric T wave inversion in V3, V4, V5 with prolonged QT were evident. Transthoracic echocardiogram showed severe systolic dysfunction with an ejection fraction of 20% and akinetic apex along with the distal left ventricular segments, consistent with Takotsubo cardiomyopathy. Myocardial contrast echocardiography showed a decrease in capillary blood flow and volume in the akinetic areas with delayed contrast replenishment, sparing the basal segments. A repeat study 2 weeks later showed near normalization of the perfusion parameters. The patient improved with medical management. A repeat echocardiogram, a month later revealed an ejection fraction of 45% with no identifiable wall motion abnormality.

Conclusion

Our case, as well as others reported previously, supports the diagnosis of Takotsubo cardiomyopathy in patients with Subarachnoid Hemorrhage who fulfill the …

Utility Of Immunohistochemical Markers In Differentiating Benign From Malignant Follicular-Derived Thyroid Nodules, Husain A. Saleh, Bo Jin, John Barnwell, Opada Alzohaili

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Thyroid nodules are common among adults though only a small percentage is malignant, which can histologically mimic benign nodules. Accurate diagnosis of these thyroid nodules is critical for the proper clinical management.

Methods

We investigated immunoexpression in 98 surgically removed benign thyroid nodules including 52 hyperplastic nodules (HN) and 46 follicular/Hurthle cell adenomas (FA), and 54 malignant tumors including 22 follicular carcinoma (FC), 20 classic papillary carcinoma (PTC), and 12 follicular variant papillary carcinoma (FVPC).

Results

The staining results showed that malignant tumors express galectin-3, HBME-1, CK19 and Ret oncoprotein significantly more than benign nodules. The sensitivity of …

Radical Nephrectomy With Ivc Thrombectomy (Level-Iii) Conducted On Veno-Veno Bypass, Tariq S. Hakky, Lucas R. Wiegand, Devannand Mangar, Angel Alsina, Philippe E. Spiess

Urology Faculty Publications

Introduction: We report a 43 year old man who was diagnosed with a level-I thrombus and was managed on oral sunitinib for two months by a community Urologist. The thrombus progressed to a level-III and he subsequently developed a pulmonary embolus, which required oral anticoagulation. He was then referred to our facility for definitive surgical care. A computed tomography scan demonstrated a 12 by 15 centimeter right renal mass and on magnetic resonance venography of the abdomen a tumor-thrombus extending into the infradiaphragmatic inferior vena cava was noted. Pre-operatively consults with hepatobiliary, vascular, and chest surgeons were obtained.

Methods: The …

Access For Laparoendoscopic Single Site Surgery, Sharona B. Ross, C. Whalen Clark, Connor A. Morton, Alexander S. Rosemurgy

Surgery Faculty Publications

Laparoscopic surgery is the standard of care for many abdominal and pelvic operations and is widely applied today. LESS (Laparo-Endoscopic Single Site) surgery, originally attempted in the 1990s, is an advanced minimally invasive approach that allows laparoscopic operations to be undertaken through a small (<15 mm) incision in the umbilicus, a preexisting scar. The presence of a preexisting scar allows LESS surgery to be essentially scarless, which is the key benefit to LESS operations. Herein, we review our experience with over 500 LESS operations and discuss the key techniques to establishing access to the peritoneal cavity. We review the options for obtaining access, available instrumentation, common challenges and solutions for access. We conclude that LESS surgery is safe and provides outcomes with superior cosmesis relative to conventional laparoscopy. LESS surgery should be embraced, as patient demand is rapidly increasing.
