The Release Of Calcium In Bacillus Anthracis Pathogenicity, Natiera Magnuson, Manomita Patra, Maria Elena Reynaga, Ernesto Abel-Santos

McNair Poster Presentations

Bacillus anthracis spores form in response to starvation and can withstand extremes of heat, radiation, and chemical toxins, making B. anthracis spores ideal vehicles for infections.1 The resistance and dormancy of bacterial spores are dependent on a largely dehydrated core.2 The spore core is not only devoid of water, but contains between 0.8 to 1M calcium complexed with 2,6-pyridinedicarboxylic acid (dipicolinic acid, DPA). The DPA-calcium complex (CaDPA) helps protect DNA, RNA, and the metabolic enzymes needed for the establishment of a vegetative cell cytoplasm.3 An anthrax infection starts with the germination of B. anthracis spores in a macrophage.4 The germinated …

Substituted Coumarin Derivatives: Synthesis And Evaluation Of Antiproliferative And Src Kinase Inhibitory Activities, Abha Kathuria, Sarah Jalal, Rakesh Tiwari, Amir Nasrolahi Shirazi, Shilpi Gupta, Shiv Kumar, Keykavous Parang, Sunil K. Sharma

Pharmacy Faculty Articles and Research

Six classes of coumarin derivatives (i.e. 3-alkyl-4-methylcoumarins, pyranocoumarins, coumarin carboxamides, quaternary ammonium coumarins, 7-aminocoumarins, and 4-aminocoumarins) were synthesized and evaluated for inhibition of cell proliferation of colon adenocarcinoma (HT-29), breast carcinoma (MDA-MB-468 or MCF-7), and human ovarian adenocarcinoma (SK-OV-3) cells. C-3-Alkyl substituted analogs of 4-methylcoumarins and pyranocoumarins, 5 and 6, inhibited the cell proliferation of MDA-MB-468 and SK-OV-3 cells by 53-74%, while 3-decyl substituted pyranocoumarin 10 and triethyl substituted quaternary ammonium coumarin derivative 29 inhibited the cell proliferation of HT-29 and SK-OV-3 cells by 63-72% at a concentration of 50 μM. Among all the compounds studied, C-3 decyl substituted quaternary …

Preventing Mother-To-Child Transmission Of Human Immunodeficiency Virus-1 (Hiv-1): Effects Of Intrapartum And Neonatal Single-Dose Nevirapine Prophylaxis And Subsequent Hiv-1 Drug Resistance At Antiretroviral Treatment Initiation, Amanda L. Harmon

CMC Senior Theses

The prevention of mother-to-child transmission is one of the most powerful tools in human immunodeficiency virus type 1 (HIV-1) prevention and has huge potential to improve both maternal and child health. In the absence of any preventative measures, infants born to and breastfed by their HIV-positive mothers have roughly a one-in-three chance of acquiring the infection themselves. HIV can be passed on from mother-to-child during pregnancy, during labor and delivery, and even after during breastfeeding.

Intrapartum and neonatal single-dose nevirapine (sd-NVP) is the foundation of preventing mother-to-child transmission in lower resource settings where it has been used alone or as …

Trends In The Clinical Characteristics Of Hiv Infected Patients Initiating Antiretroviral Therapy In Kenya, Uganda And Tanzania Between 2002 And 2009, Elvin H. Geng, Peter W. Hunt, Lameck O.

Publications and Research

Background: East Africa has experienced a rapid expansion in access to antiretroviral therapy (ART) for HIVinfected patients. Regionally representative socio-demographic, laboratory and clinical characteristics of patients accessing ART over time and across sites have not been well described.

Methods: We conducted a cross-sectional analysis of characteristics of HIV-infected adults initiating ART between 2002 and 2009 in Kenya, Uganda and Tanzania and in the International Epidemiologic Databases to Evaluate AIDS Consortium. Characteristics associated with advanced disease (defined as either a CD4 cell count level of less than 50 cells/mm3 or a WHO Stage 4 condition) at the time of ART initiation …

Androgen Receptor-Dependent Effects Of Resveratrol On Tnsin Mrna Levels In Prostate Cancer Cells, Courtney Pisano

PCOM Biomedical Studies Student Scholarship

The chemopreventive effects of resveratrol (RSV) on cancers, including prostate cancer, have been well documented; but the mechanisms are not well known. It has been reported recently that tensin, a matrix-adhesion protein, which is greatly down-regulated in prostate cancer, has been induced by RSV in several cancer cell lines. In order to know if RSV up-regulates tensin in prostate cells, we first treated LNCaP cells with RSV and demonstrated that tensin mRNA levels were upregulated by RSV in a time and dose dependent manner. Since LNCaP cells are androgen receptor (AR) positive and previous findings have shown that RSV down-regulates …

The Role Of Ghrelin And Leptin In Obesity: Is Exogenous Administration Of These Hormones A Possible Drug Therapy?, Peri Eckstein

The Science Journal of the Lander College of Arts and Sciences

Ghrelin and leptin are two hormones that have been recognized to have a major influence on energy balance. Leptin is a mediator of long term regulation of energy balance, suppressing food intake and thereby inducing weight loss. Ghrelin, on the other hand, is a fast acting hormone, playing a role in meal initiation. As a growing number of people suffer from obesity, understanding the mechanisms by which various hormones and neurotransmitters influence energy balance has been a subject of intense research. This paper provides background on leptin and ghrelin hormones, their role in food intake and body weight in humans, …

Health Risks Of Very Low Cholesterol, Menachem Nagar

The Science Journal of the Lander College of Arts and Sciences

Cholesterol is a molecule central to all human physiological processes at systemic as well as cellular levels. Cholesterol, combined with Apolipoprotein B as low-density lipoprotein (LDL) has been the focus of scientific research because the molecule has been proven to play a role in the development of cardiovascular disease, a disease of pandemic proportions. Considerable scientific and medical attention has been devoted to identifying the role and management of high levels of total serum cholesterol in order to address this global health burden, creating large scale awareness regarding lowering cholesterol concentration in circulation. However, the same molecule, combined into various …

The Effect Of Melatonin On The Ovaries, Jaclyn Starr

The Science Journal of the Lander College of Arts and Sciences

Melatonin is a very small molecule whose effects can be both detrimental and beneficial to the ovaries depending on its concentration. Too much of anything is usually not good and so is the case with melatonin. Very high doses can be damaging, but in the right amount melatonin may be able to combat various diseases and increase the chances for fertility in women.
