Abnormal Dendritic Maturation Of Developing Cortical Neurons Exposed To Corticotropin Releasing Hormone (Crh): Insights Into Effects Of Prenatal Adversity?, Megan M. Curran, Curt A. Sandman, Elysia Poggi Davis, Laura M. Glynn, Tallie Z. Baram

Psychology: Faculty Scholarship

Corticotropin releasing hormone (CRH) produced by the hypothalamus initiates the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the body’s stress response. CRH levels typically are undetectable in human plasma, but during pregnancy the primate placenta synthesizes and releases large amounts of CRH into both maternal and fetal circulations. Notably, placental CRH synthesis increases in response to maternal stress signals. There is evidence that human fetal exposure to high concentrations of placental CRH is associated with behavioral consequences during infancy and into childhood, however the direct effects on of the peptide on the human brain are unknown. In this study, we used a …

Department of Dermatology and Cutaneous Biology Faculty Papers

Cultural competency continues to gain increased attention in medicine. Not only does it play a significant role in the delivery of health care and patient outcomes, but it also remains a major determinant of patient satisfaction. This study investigated how patients in an urban dermatology clinic rated their satisfaction with cultural competency. Compared to White patients, satisfaction scores were greater for Hispanic or Latino patients and less for Asian patients, while there was no significant difference for Black or African American patients. There were clear differences in patient satisfaction rates of various dimensions of cultural competency. A follow-up study with …

Inhibition Of Age-Related Therapy Resistance In Melanoma By Rosiglitazone-Mediated Induction Of Klotho., Reeti Behera, Amanpreet Kaur, Marie R. Webster, Suyeon Kim, Abibatou Ndoye, Curtis H. Kugel, Gretchen M. Alicea, Joshua Wang, Kanad Ghosh, Phil Cheng, Sofia Lisanti, Katie Marchbank, Vanessa Dang, Mitchell Levesque, Reinhard Dummer, Xiaowei Xu, Meenhard Herlyn, Andrew E. Aplin, Alexander Roesch, Cecilia Caino, Dario C. Altieri, Ashani T. Weeraratna

Department of Cancer Biology Faculty Papers

Purpose: Aging is a poor prognostic factor for melanoma. We have shown that melanoma cells in an aged microenvironment are more resistant to targeted therapy than identical cells in a young microenvironment. This is dependent on age-related secreted factors. Klotho is an age-related protein whose serum levels decrease dramatically by age 40. Most studies on klotho in cancer have focused on the expression of klotho in the tumor cell. We have shown that exogenous klotho inhibits internalization and signaling of Wnt5A, which drives melanoma metastasis and resistance to targeted therapy. We investigate here whether increasing klotho in the aged microenvironment …

Intracellular Ca 2+ Sensing: Role In Calcium Homeostasis And Signaling, Rafaela Bagur, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Ca²⁺ is a ubiquitous intracellular messenger that controls diverse cellular functions but can become toxic and cause cell death. Selective control of specific targets depends on spatiotemporal patterning of the calcium signal and decoding it by multiple, tunable, and often strategically positioned Ca²⁺-sensing elements. Ca²⁺ is detected by specialized motifs on proteins that have been biochemically characterized decades ago. However, the field of Ca²⁺ sensing has been reenergized by recent progress in fluorescent technology, genetics, and cryo-EM. These approaches exposed local Ca²⁺-sensing mechanisms inside organelles and at the organellar interfaces, revealed how Ca …

Department of Surgery Faculty Papers

Predictive biomarkers have the potential to facilitate cancer precision medicine by guiding the optimal choice of therapies for patients. However, clinicians are faced with an enormous volume of often-contradictory evidence regarding the therapeutic context of chemopredictive biomarkers.We extensively surveyed public literature to systematically review the predictive effect of 7 biomarkers claimed to predict response to various chemotherapy drugs: ERCC1-platinums, RRM1-gemcitabine, TYMS-5-fluorouracil/Capecitabine, TUBB3-taxanes, MGMT-temozolomide, TOP1-irinotecan/topotecan, and TOP2A-anthracyclines. We focused on studies that investigated changes in gene or protein expression as predictors of drug sensitivity or resistance. We considered an evidence framework that ranked studies from high level I evidence for randomized …

Patients’ Level Of Knowledge And Perception Of The Involvement Of Post-Graduate Trainees In Their Surgical Care At Aga Khan University Hospital, Nairobi., Jane Mugure Githae

Master of Medicine in General Surgery

Introduction: Surgical training is fashioned on a system of graduated responsibilities and independence for acquisition of skills and competence. While many benefit from acquisition of these skills, few would want to be the ‘practicing ground’ for the trainee surgeon. Moreover, disclosure is inappropriate and surgical care does not specifically spell out the role of the surgical trainee in these procedures. A pilot survey conducted on 20 first-time patients presenting to General Surgery and Orthopaedic Clinics at Aga Khan University Hospital, Nairobi, revealed varied understandings as to who is a post-graduate surgical trainee. Objective: To explore the patients’ level of knowledge …

Targeting Ledgf/P75 To Sensitize Chemoresistant Prostate Cancer Cells To Taxanes, Leslimar Rios-Colón

Loma Linda University Electronic Theses, Dissertations & Projects

Prostate cancer (PCa) is the second most diagnosed cancer in males. This disease disproportionately affects African American men, with a higher incidence and mortality compared to other ethnic/racial groups. An aging male population and the complexity of addressing the health disparities associated with this disease puts PCa into the spotlight due to its serious public health implications and the imminent fiscal challenge over the next decades. Chronic prostate inflammation resulting in activation of stress and prosurvival pathways contribute to disease progression and the development of chemoresistance. Lens epithelium-derived growth factor p75 (LEDGF/p75) is a stressresponse protein that promotes cellular survival …

Loma Linda University Electronic Theses, Dissertations & Projects

Despite the significant progress in implementing palliative care interventions for cancer patients, few intervention studies seek healthcare clinicians’ input prior to implementation. The purpose of this research was then to explore palliative care and oncology clinicians’ (e.g., physicians, nurses, social workers, and chaplains) perspectives on current challenges and useful practices in meeting the quality of life needs of lung cancer patients and family caregivers, and to increase the likelihood of the adoption of a palliative care intervention based on understanding current trends in palliative care delivery at three outpatient oncology sites. The conceptual framework used for this study was the …

Hypertonic Saline Versus Mannitol To Improve Brain Relaxation In Craniotomy: A Case Study, Morgan Cornell

Nurse Anesthesia MSNA Student Capstones

In neurosurgical procedures, including craniotomy for tumor, neurosurgeons often require a reduction of brain swelling to optimally perform the surgery. The reduction of brain swelling is termed brain relaxation. The anesthesia professional can accomplish brain relaxation using multiple techniques. One such technique is the infusion of certain intravenous fluids to change the osmotic pressure within the cranial vault thereby reducing brain edema (Jaffe, 2014). Highly osmolar fluids such as mannitol and hypertonic saline can be infused to decrease brain edema. Currently, mannitol remains the gold standard for medical treatment of intracranial pressure in neurosurgical procedures (Marko, 2012). This review seeks …

Pancreatic ductal adenocarcinoma (PDA) is the third leading cause of cancer-related deaths in the United States, whereas colorectal cancer is the third most common cancer. The RNA-binding protein HuR (ELAVL1) supports a pro-oncogenic network in gastrointestinal (GI) cancer cells through enhanced HuR expression. Using a publically available database, HuR expression levels were determined to be increased in primary PDA and colorectal cancer tumor cohorts as compared with normal pancreas and colon tissues, respectively. CRISPR/Cas9 technology was successfully used to delete the HuR gene in both PDA (MIA PaCa-2 and Hs 766T) and colorectal cancer (HCT116) cell lines. HuR deficiency has …

White Blood Cell Subtypes Are Associated With A Greater Long-Term Risk Of Death After Acute Myocardial Infarction, Arthur Shiyovich, Harel Gilutz, Ygal Plakht

The Texas Heart Institute Journal

We evaluated the association between white blood cell counts and long-term mortality rates in 2,129 patients (mean age, 65.3 ± 13.5 yr; 69% men) who had survived acute myocardial infarction. We obtained white blood cell counts and differential counts of white blood cell subtypes within the first 72 hours of hospital admission. The primary outcome was all-cause death at 1, 5, and 10 years after acute myocardial infarction.

In regard to death in the long term, we found significant negative linear associations (lymphocytes), positive linear associations (neutrophils and the neutrophil-to-lymphocyte ratio), and nonlinear U-shaped associations (basophils, eosinophils, monocytes, and total …
