Maternal And Neonatal Health Services In Sudan: Results Of A Situation Analysis, Nahla G. Abdel-Tawab, Maha El-Rabbat

Reproductive Health

This project brief is based on the results of a situation analysis (SA) study that was done collaboratively by the Population Council and Sudan Ministry of Health (MOH) with funds from UNFPA, UNICEF, and Packard Foundation. The analysis showed an uneven distribution of reproductive health (RH) staff across Sudan, and nurses and nurse midwives are the key in RH services. There was also limited access to family planning services. Antenatal care was limited, and pregnant women in the study seldom received counseling on birth spacing or birth preparedness. Birth attendants also lacked adequate knowledge and skills. Emergency obstetric care was …

Solar Simulated Radiation Induced Cell Death Depends On Spectral Distribution And Irradiance But Not Output Delivery, Alanna Maguire, Fiona Lyng, James Walsh Jan 2010

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 …


The Effects Of Pet Ownership On Physical Well-Being In Older Adults, Tami Pohnert Jan 2010

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

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 Jan 2010

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 …

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.

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.

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 …

Obstetrics and Gynaecology, East Africa

Sport has become a popular tool for HIV prevention, based on claims that it can foster life skills that are necessary to translate knowledge, attitudes and behavioural intentions into actual behaviour. Empirical evidence of the effectiveness of sport-based HIV prevention programmes is, however, sorely lacking. We therefore conducted a cross-sectional survey assessing sexual behaviour and the determinants thereof among 454 youth of the Mathare Youth Sport Association (MYSA) in Kenya and a control group of 318 non-MYSA members. Multiple (ordinal) logistic regression models were applied to measure the association between MYSA membership and attitudes, subjective norms and self-efficacy related to …

Outcome measure: self- and parent reports of grades in school. Effects of media exposures on change in school performance between baseline and 24 months were assessed using structural equation modeling. Information about hypothesized …


Proteomic Analysis Of Plasma Exosomes Reveals That Kappa:Lambda Ratio Predicts Severe Acute Graft-Versus-Host Disease, Joseph Alge Jan 2010

Proteomic Analysis Of Plasma Exosomes Reveals That Kappa:Lambda Ratio Predicts Severe Acute Graft-Versus-Host Disease, Joseph Alge

MUSC Theses and Dissertations

Background: Acute Graft-Versus-Host disease (acute GVH D) is an often fatal, inflammatory multi-organ disease driven by T cell alloreactivity directed toward host tissues. One of the chief obstacles to improving outcomes of acute GVHD patients is timely diagnosis. Currently, acute GVHD is diagnosed clinically, once the symptoms are fully manifested. However, it is clear that important immunologic events occur prior to the occurrence of symptoms. A biomarker that could predict disease during the asymptomatic period could improve patient outcomes by allowing for earlier intensification of immunosuppressant therapy. Exosomes are an attractive target for acute GVHD biomarker discovery. They contain a …


Increasing Postpartum Contraception In Rural Uttar Pradesh: Implications For Behavior Change Communication, Population Council Jan 2010

Increasing Postpartum Contraception In Rural Uttar Pradesh: Implications For Behavior Change Communication, Population Council

Reproductive Health

The Population Council conducted a formative study in rural Uttar Pradesh, India to assess the level of adoption of postpartum contraception for spacing among low parity women, identify the facilitating factors and barriers to the adoption of this target behavior, and identify programmatic and behavior change communications (BCC) initiatives that could accelerate the adoption of postpartum contraception for spacing and improve the service delivery system, if required, to facilitate the process. Barriers included low awareness of consequences of closely spaced births, misconceptions about contraceptive methods, lack of counseling by health workers, reluctance to include husbands, and programmatic emphasis on limiting …

Quantification Of Circulating Melanoma Cells, Jamie Freeman Jan 2010

Quantification Of Circulating Melanoma Cells, Jamie Freeman

Theses : Honours

Current prognostic techniques for Cutaneous Malignant Melanoma (CMM), a highly aggressive and drug resistant skin cancer, are inadequate at managing the disease and identifying early stage patients requiring treatment. It is thought that Circulating Tumour Cells (CTCs), which circulate in patient blood after being shed from solid tumours, may be useful in enhancing prognostic techniques and it has previously been shown in other malignancies that the presence of CTCs in patient blood is associated with poor prognosis. In CMM, CTCs can be detected through RT-PCR for melanoma associated markers, although this technique does not allow CTCs to be quantified. In …

A Novel Curriculum Using Simulation To Teach And Assess Indications And Technique Of Handwashing To Gme Learners, K. Berg, C. Sultana, R. Sorokin, J. Kairys, M. Vergare, D. Berg

Department of Obstetrics and Gynecology Faculty Papers

Proficiency in the clinical skill of effective hand washing is integral to high quality health care. Studies at our hospital revealed that in 2008, of 1215 direct, anonymous, observations of residents and attendings, only 53.3% washed their hands correctly during clinical activities. Medical students in fiscal year 2009 (July 1, 2008-June 30 2009) had a 52% compliance rate from 109 observations. This data prompted our hospital to work with the faculty of the University Clinical Skills and Simulation Center (UCSSC) to develop a module on the indications and technique of effective handwashing. This intervention, using multimedia simulation was introduced to …

Mast Cells And Hypoxia Drive Tissue Metaplasia And Heterotopic Ossification In Idiopathic Arthrofibrosis After Total Knee Arthroplasty., Theresa A Freeman, Javad Parvizi, Craig J Dela Valle, Marla J Steinbeck

Department of Orthopaedic Surgery Faculty Papers

ABSTRACT: BACKGROUND: Idiopathic arthrofibrosis occurs in 3-4% of patients who undergo total knee arthroplasty (TKA). However, little is known about the cellular or molecular changes involved in the onset or progression of this condition. To classify the histomorphologic changes and evaluate potential contributing factors, periarticular tissues from the knees of patients with arthrofibrosis were analyzed for fibroblast and mast cell proliferation, heterotopic ossification, cellular apoptosis, hypoxia and oxidative stress. RESULTS: The arthrofibrotic tissue was composed of dense fibroblastic regions, with limited vascularity along the outer edges. Within the fibrotic regions, elevated numbers of chymase/fibroblast growth factor (FGF)-expressing mast cells were …


Enhancement Of Autophagy During Lytic Replication By The Kaposi’S Sarcoma-Associated Herpesvirus Replication And Transcription Activator, Hui-Ju Wen, Zhilong Yang, You Zhou, Charles Wood Jan 2010

Enhancement Of Autophagy During Lytic Replication By The Kaposi’S Sarcoma-Associated Herpesvirus Replication And Transcription Activator, Hui-Ju Wen, Zhilong Yang, You Zhou, Charles Wood

Nebraska Center for Virology: Faculty Publications

Autophagy is one of two major degradation systems in eukaryotic cells. The degradation mechanism of autophagy is required to maintain the balance between the biosynthetic and catabolic processes and also contributes to defense against invading pathogens. Recent studies suggest that a number of viruses can evade or subvert the host cell autophagic pathway to enhance their own replication. Here, we investigated the effect of autophagy on the KSHV (Kaposi’s sarcoma-associated herpesvirus) life cycle. We found that the inhibition of autophagy reduces KSHV lytic reactivation from latency, and an enhancement of autophagy can be detected during KSHV lytic replication. In addition, …

Synaptic Clustering Of Psd-95 Is Regulated By C-Abl Through Tyrosine Phosphorylation, Karen Perez De Arce, Lorena Varela-Nallar, Olivia Farias, Alejandra Cifuentes, Paulina Bull, Brian A. Couch, Anthony J. Koleske, Nibaldo C. Inestrosa, Alejandra R. Alvarez

School of Biological Sciences: Faculty Publications

The c-Abl tyrosine kinase is present in mouse brain synapses, but its precise synaptic function is unknown. We found that c-Abl levels in the rat hippocampus increase postnatally, with expression peaking at the first postnatal week. In 14 d in vitro hippocampal neuron cultures, c-Abl localizes primarily to the postsynaptic compartment, in which it colocalizes with the postsynaptic scaffold protein postsynaptic density protein-95 (PSD-95) in apposition to presynaptic markers. c-Abl associates with PSD-95, and chemical or genetic inhibition of c-Abl kinase activity reduces PSD-95 tyrosine phosphorylation, leading to reduced PSD-95 clustering and reduced synapses in treated neurons. c-Abl can phosphorylate …

Purification Of Parvalbumin From Carp: A Protocol That Avoids Heat Treatment, Stef J. Koppelman, Roland A. Romijn, Harmen H. J. De Jongh, Julie A. Nordlee, Sander Piersma, Martin Hessing, Steve L. Taylor

Department of Food Science and Technology: Faculty Publications

Parvalbumin from carp, a major allergen,was purified to homogeneity using ion exchange chromatography and size exclusion chromatography (estimated purity > 95% to 98% based on SDS-PAGE and native PAGE) with a yield of 318 mg, and a number of basic biochemical characteristics were determined. The identity was confirmed by peptide-mass fingerprinting, and IgE-binding was demonstrated. The UV/Vis absorbance spectra were explained using the previously published amino acid sequences. Far UV-CD spectroscopy was used to confirm the folding character of parvalbumin. We conclude that parvalbumin from carp can be purified on a comparatively large (hundreds of milligrams) scale using a purification protocol …


A Specific Regulatory Role For Sgtα On The Maturation And Activation Of Steroid Hormone Receptors, Atanu Paul Jan 2010

A Specific Regulatory Role For Sgtα On The Maturation And Activation Of Steroid Hormone Receptors, Atanu Paul

Open Access Theses & Dissertations

Steroid hormone receptors (SHRs) are ligand-dependent transcription factors belonging to the nuclear receptor superfamily. These receptors regulate various physiological functions in higher ordered eukaryotes. In the absence of hormone these receptors form a complex with molecular chaperones such as Hsp90 and Hsp70 and other cochaperones in the cytoplasm. Association with the Hsp90-Hsp70 chaperone machinery leads to the maturation of the Ligand Binding Domain (LBD) of the receptors and enables the receptors to bind hormone with high affinity. Upon binding with a specific hormone the receptors are translocated into the nucleus where they initiate transcription of specific genes. Although the involvement …

Identification Of A Novel Cytokine Inducible Stat5 Phosphoserine Site (Ps193) That Positively Regulates Its Transcriptional Activity And Is Found Constitutively Activated In Certain Hematopoietic Cancers, Abhisek Mitra

Open Access Theses & Dissertations

Hematological malignancies such as leukemia and lymphoma, can develop from aberrant changes in the cell signaling molecules to drive their uncontrolled cellular proliferation and differentiation. Activation, maturation, expansion and differentiation of T cells are critically regulated by the dynamics of various transcription factors activated by a variety of cytokines. Additionally, multiple effector molecules that mediate these T cells dependent signals include the JAK (Janus Kinase)-STAT (Signal transducer and activator of transcription) cascade. These signaling proteins are activated in response to a broad array of cytokines. Constitutively activated JAKs and STATs have been described in several T cell malignancies. A growing …
