Sediment cores taken near extant springs along the western margin of Soda Lake playa, as well as from the playa center, reveal dramatic hydrologic changes that occurred in the central Mojave Desert during the late Quaternary. Results of stratigraphic

We describe indirect genetic benefits of mate choice in two allopatric populations of cactophilic Drosophila mojavensis. By manipulating mate choice opportunity, we show that greater mate choice among sexually mature adults leads to shorter offspring

2 Abstract Sexual signals in cactophilic Drosophila mojavensis include cuticular hydrocar- bons (CHCs), contact pheromones that mediate female discrimination of males during courtship. CHCs, along with male courtship songs, cause premating isolation

Large-area displays and light valves can be made by dispersing nematic liquid-crystal droplets in a polymer matrix. To switch between scattering and transparent states of the polymer film, an electric field is used to alter the refractive index of th

Understanding the regulation and control of heme/porphyrin biosynthesis is critical for the optimization of the delta-aminolevulinic-acid (ALA)-mediated photodynamic therapy of cancer, in which endogenously produced protoporphyrin IX (PPIX) is the ph

Recently, we reported that the delta-aminolevulinic acid (delta-ALA)-induced increase in porphobilinogen deaminase (PBGD) activity was closely correlated with an increase in the accumulation of protoporphyrin IX (PPIX), resulting in augmented phototo

Photodynamic therapy (PDT), a novel treatment for a variety of human malignancies, usually consists of visible light irradiation of lesions following the systemic administration of a photosensitizer. Induction of the endogenous photosensitizer protop

This study examined the relationship between human immunodeficiency virus (HIV) infection and psychiatric morbidity within the context of prenatal drug exposure. Twenty-six HIV-infected, 14 seroreverted, and 20 control (non-HIV-exposed) children were
