When Birth Control Hurts You: An Essure Investigation, Mia A. Garchitorena Dec 2015

When Birth Control Hurts You: An Essure Investigation, Mia A. Garchitorena

Capstones

Thousands of women report having suffered from injuries and malfunctions related to Essure permanent birth control, including chronic pain, heavy bleeding, migration, or perforation. Many of these women also claim that Essure has caused nickel allergies, hair loss, bloating, rashes, unintended pregnancies, and death. What was promised to be an easy solution has become a life-altering problem.

As patient complaints have increased, experts have gone back and studied the science behind the approval of the Essure device. Their findings are startling: There were flaws with the studies that supported the Food and Drug Administration’s approval of the device, the experts …

How N.Y.'s Biggest For-Profit Nursing Home Group Flourishes Despite a Record of Patient Harm

The state’s “character-and-competence” reviews are supposed to weed out operators with histories of violations and fines— but regulators don’t always act on the full story.


Hot Spot Mutation In Tp53 (R248q) Causes Oncogenic Gain-Of-Function Phenotypes In A Breast Cancer Cell Line Derived From An African American Patient, Nataly Shtraizent, Hiroshi Matsui, Alla Polotskaia, Jill Bargonetti Dec 2015

Hot Spot Mutation In Tp53 (R248q) Causes Oncogenic Gain-Of-Function Phenotypes In A Breast Cancer Cell Line Derived From An African American Patient, Nataly Shtraizent, Hiroshi Matsui, Alla Polotskaia, Jill Bargonetti

Publications and Research

African American (AA) breast cancer patients often have triple negative breast cancer (TNBC) that contains mutations in the TP53 gene. The point mutations at amino acid residues R273 and R248 both result in oncogenic gain-of-function (GOF) phenotypes. Expression of mutant p53 (mtp53) R273H associates with increased cell elasticity, survival under serum deprivation conditions, and increased Poly (ADP ribose) polymerase 1 (PARP1) on the chromatin in the AA-derived TNBC breast cancer cell line MDA-MB-468. We hypothesized that GOF mtp53 R248Q expression could stimulate a similar phenotype in the AA-derived TNBC cell line HCC70. To test this hypothesis we depleted the R248Q …

International dissemination of evidence-based interventions calls for rigorous evaluation. As part of an evaluation of critical time intervention (CTI) for homeless people and abused women leaving Dutch shelters, this study assessed fidelity in two service delivery systems and explored factors influencing model adherence. Data collection entailed chart review (n = 70) and two focus groups with CTI workers (n = 11). The intervention obtained an overall score of three out of five (fairly implemented) for compliance fidelity and chart quality combined. Fidelity did not differ significantly between service systems, supporting its suitability for a range of populations. The eight themes …

Cladribine, 2-chloro-2′-deoxyadenosine, is a highly efficacious, clinically used nucleoside for the treatment of hairy cell leukemia. It is also being evaluated against other lymphoid malignancies and has been a molecule of interest for well over half a century. In continuation of our interest in the amide bond-activation in purine nucleosides via the use of (benzotriazol-1yl-oxy)tris(dimethylamino)phosphonium hexafluorophosphate, we have evaluated the use of O6-(benzotriazol-1-yl)-2′-deoxyguanosine as a potential precursor to cladribine and its analogues. These compounds, after appropriate deprotection, were assessed for their biological activities, and the data are presented herein. Against hairy cell leukemia (HCL), T-cell lymphoma (TCL) and chronic lymphocytic …

Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi Jul 2015

Nitric Oxide-Releasing Aspirin Suppresses Nf-Κb Signaling In Estrogen Receptor Negative Breast Cancer Cells In Vitro And In Vivo, Niharika Nath, Mitali Chattopadhyay, Deborah B. Rodes, Anna Nazarenko, Ravinder Kodela, Khosrow Kashfi

Publications and Research

Estrogen receptor negative (ER(−)) breast cancer is aggressive, responds poorly to current treatments and has a poor prognosis. The NF-κB signaling pathway is implicated in ER(−) tumorigenesis. Aspirin (ASA) is chemopreventive against ER(+) but not for ER(−) breast cancers. Nitric oxide-releasing aspirin (NO-ASA) is a safer ASA where ASA is linked to an NO-releasing moiety through a spacer. In vitro, we investigated anti-proliferation effects of NO-ASA (para- and meta-isomers) against ER(−) breast cancer cells MDA-MB-231 and SK-BR-23, effects on NF-κB signaling, and reactive oxygen species by standard techniques. In vivo, effects of NO-ASA were evaluated in a mouse xenograft model …


Non-Operative Management Of Hip Osteoarthritis, Ray Marks Jun 2015

Non-Operative Management Of Hip Osteoarthritis, Ray Marks

Publications and Research

This paper reviews several non-operative and non-pharmacologic management strategies advocated for alleviating the pain and disability experienced by people with hip osteoarthritis. It analyzes whether painful debilitating hip osteoarthritis, which has no effective cure and is often progressive, may be affected positively by non-operative interventions designed to control osteoar- thritis pain. Finally, it provides an integrated plan of management for ameliorating hip osteoar- thritis pain and disability in light of this knowledge.

Background: Diabetes is predicted to increase in incidence by 42% from 1995 to 2025. Although most adults with diabetes seek care from primary care practices, adherence to treatment guidelines in these settings is not optimal. Many practices lack the infrastructure to monitor patient adherence to recommended treatment and are slow to implement changes critical for effective management of patients with chronic conditions. Supporting Practices to Adopt Registry-Based Care (SPARC) will evaluate effectiveness and sustainability of a low-cost intervention designed to support work process change in primary care practices and enhance focus on population-based care through implementation of a diabetes …


The Regulatory Function Of Sphingosine-1-Phosphate Signaling Axis On Regulatory T Cells In Colorectal Cancer, Andrew V. Nguyen, Yuan-Yuan Wu, Elaine Y. Lin Feb 2015

The Regulatory Function Of Sphingosine-1-Phosphate Signaling Axis On Regulatory T Cells In Colorectal Cancer, Andrew V. Nguyen, Yuan-Yuan Wu, Elaine Y. Lin

Publications and Research

In tumors associated with inflammation such as inflammatory bowel disease (IBD) and colorectal cancer (CRC), high numbers of regulatory T cells (Tregs) are associated with both favorable and poor prognoses. The functions of Tregs in CRC remain elusive and have yet to be clearly defined. With new evidence supporting many subsets of Tregs, the research on the development and functions of these cells has begun to come to fruition. The sphingosine 1 phosphate (S1P) pathway was recently reported to regulate the development and function of regulatory T cells. This pathway may shine new light into the pleiotropic nature of these …

Dissertations, Theses, and Capstone Projects

Orchestrated expression of multiple genes residing in the complex TCRα/δ/Dad1 locus requires tight control from multiple cis-acting elements. The TCRα locus control region (LCR), is positioned between TCRα and Dad1 gene, and has been implicated in the differential expression of both genes. In this study, we focus our work on the hypersensitive site (HS)1 prime (HS1'), located 3' of the classical Eα enhancer, within the TCRα LCR. We investigated its non- redundant role in TCRα expression in thymic and peripheral T cells as assayed by in vivo and in vitro studies. Furthermore, formation of HS1' in both lymphoid and …

Publications and Research

Following recent work on heterometallic titanocene–gold complexes as potential chemotherapeutics for renal cancer, we report here on the synthesis, characterization and stability studies of new titanocene complexes containing a methyl group and a carboxylate ligand (mba ¼ S–C6H4–COO) bound to gold(I)-phosphane fragments through a thiolate group [(h-C5H5)2TiMe(m-mba)Au(PR3)]. The compounds are more stable in physiological media than those previously reported and are highly cytotoxic against human cancer renal cell lines. We describe here preliminary mechanistic data involving studies on the interaction of selected compounds with plasmid (pBR322) DNA used as a model nucleic acid, and with selected protein kinases from a …
