In the Drosophila visual system, the color-sensing photoreceptors R7 and R8 project their axons to two distinct layers in the medulla. Loss of the receptor tyrosine phosphatase LAR from R7 photoreceptors causes their axons to terminate prematurely in the R8 layer. Here we identify a null mutation in the Lipringene based on a similar R7 projection defect. Liprinphysically interacts with the inac...

The present study examined the effects of multimedia instructional material on students’ learning and their perceptions of the instruction. A between-group quasiexperimental study design was used for the purpose of this study. One hundred eleven students enrolled in a Quantity Food Production laboratory class in two different semesters were designated to either the control or experimental group...

BACKGROUND Oxidative stress and redox-regulating enzymes may potentially accelerate pancreatic carcinogenesis and also affect chemoresistance. Recently major antioxidant response regulator NF-E2-related factor 2 (Nrf2) has been linked to poor prognosis in pancreatic cancer. Nrf2 activity is strictly regulated by oxidative stress sensor Kelch-like ECH-associated protein 1 (Keap1). Oxidative DNA ...

All the research projects discussed here were conducted in collaboration with either one of two independent research agencies based in the UK, GfkNOP or Illuminas. This discussion will draw upon three key studies. A qualitative study composed of focus groups and teledepth interviews completed in 2003–2004 which delved into the motivations and perceptions towards peer review specifically the opi...

The conclusions and opinions expressed here are those of the authors alone. Abstract Purpose. While prior research has demonstrated that many adolescents engage in non-coital sexual behavior, extant peer-reviewed studies have not used nationally representative data or multivariate methods to examine these behaviors. We used data from Cycle 6 of National Survey of Family Growth (NSFG) to explore...

INTRODUCTION Leishmaniasis is a zoonotic disease caused by protozoa of the genus Leishmania . Cutaneous leishmaniasis is the most common form, with millions of new cases worldwide each year. Treatments are ineffective due to the toxicity of existing drugs and the resistance acquired by certain strains of the parasite. METHODS We evaluated the activity of sodium nitroprusside in macrophages in...

There are many distinct strains of scrapie agent, identified by their relative incubation periods and quantitative and qualitative neuropathological properties in inbred mice of particular genotypes. When serially passaged under specified conditions of mouse strain, route of infection and dose of infectivity these properties are stable. However, they may change in a predictable manner if the pa...

OBJECTIVE To examine the opinions of pediatricians and pediatric psychologists concerning prescription privileges for psychologists. METHODS 213 pediatric psychologists and 119 pediatricians returned surveys regarding their opinions about cost, access, and quality of psychological care if psychologists had prescription privileges. RESULTS Pediatric psychologists had significantly more posit...
