Lead-contaminated candies from Latin America are beginning to gain attention in the public media1,2 and in the medical literature.3–5 These candies come from a number of sources and are manufactured outside Food and Drug Administration regulatory control. In 2005, we sampled 50 imported Latin American candies sold in Southern Nevada. A total of 20 (40%) tested positive with an average lead content of 1.46  0.27 mg/kg in the candies’ wrappers and straws, based on standard Graphite Furnace Atomic Absorption Spectrophotometry methodology. Given these results, the Southern Nevada Health District issued a cease-and-desist order on February 13, 2006, to local …

Evidence accumulated over more than two decades has implicated Ca2+ dysregulation in brain aging and Alzheimer's disease (AD), giving rise to the Ca2+ hypothesis of brain aging and dementia. Electrophysiological, imaging, and behavioral studies in hippocampal or cortical neurons of rodents and rabbits have revealed aging-related increases in the slow afterhyperpolarization, Ca2+ spikes and currents, Ca2+transients, and L-type voltage-gated Ca2+ channel (L-VGCC) activity. Several of these changes have been associated with age-related deficits in learning or memory. Consequently, one version of the Ca2+ hypothesis has been that increased L-VGCC activity drives many of the other Ca2+-related biomarkers of hippocampal aging. …

The Status Of Childhood Lead Poisoning And Prevention In Nevada, Usa, Anne Rothweiler, Elena E. Cabb, Shawn Gerstenberger Jan 2007

The Status Of Childhood Lead Poisoning And Prevention In Nevada, Usa, Anne Rothweiler, Elena E. Cabb, Shawn Gerstenberger

Environmental & Occupational Health Faculty Publications

One of the first steps in addressing the problem of childhood lead poisoning is to identify the possible sources of exposure in specific communities and target high-risk populations with appropriate interventions. Due to several factors, such as lack of funding and lack of blood lead reporting, little information exists regarding the occurrence of childhood lead poisoning and the prevalence of potential exposure sources in the state of Nevada. Following the recent establishment of a Nevada-based Lead Poisoning Program, we compiled the most current information available on Nevadans, and use this knowledge to suggest future research objectives and outreach activities for …


Design, Synthesis, And Evaluation Of 10-N-Substituted Acridones As Novel Chemosensitizers In Plasmodium Falciparum, Jane X. Kelly, Martin J. Smilkstein, Roland A. Cooper, Kristin D. Lane, Robert A. Johnson, Aaron Janowsky, Rozalia A. Dodean, David J. Hinrichs, Rolf Winter, Michael Riscoe Jan 2007

A series of novel 10-N-substituted acridones, bearing alkyl side chains with tertiary amine groups at the terminal position, were designed, synthesized, and evaluated for the ability to enhance the potency of quinoline drugs against multidrug-resistant (MDR) Plasmodium falciparum malaria parasites. A number of acridone derivatives, with side chains bridged three or more carbon atoms apart between the ring nitrogen and terminal nitrogen, demonstrated chloroquine (CQ)-chemosensitizing activity against the MDR strain of P. falciparum (Dd2). Isobolograrn analysis revealed that selected candidates demonstrated significant synergy with CQ in the CQ-resistant (CQR) parasite Dd2 but only additive (or indifferent) interaction in the CQ-sensitive …
