The study is based on the work histories and mortality data for 3832 male workers first employed before 1967 at a copper smelter in northern Sweden and followed up from 1950 to 1981. From the 3832 workers a lead cohort consisting of 437 workers employed for at least three years at sites with considerable lead exposure during 1950-74 was selected. These workers had regularly had blood lead measu...

In 1928 Krebs reported that the concentration of copper in the serum was significantly raised in the terminal stages of pregnancy. Since that time this observation has been confirmed by a number of workers (Gorter, Grendel, and Weyers, 1931; Locke, Main, and Rosbash, 1932; Sachs, Levine, and Fabian, 1935; Nielsen, 1944), who have shown that at full term the serum copper level is approximately t...

The aerial spray prediction model AgDRIFT embodies the computational engine found in the near-wake Lagrangian model AGricultural DISPersal (AGDISP) but with several important features added that improve the speed and accuracy of its predictions. This article summarizes those changes, describes the overall analytical approach to the model, and details model implementation, application, limits, a...

Several new descriptions of colorimetric methods for the determination of blood sugar have been described in recent years (for example, Polis and Sortwell, 1946; Somogyi, 1945; Nelson, 1944; Haslewood and Strookman, 1939). These procedures are all based on the use of alkaline copper reagents and on the production of molybdenum blue by the action of cuprous copper on complex molybdic acid soluti...

Berry color is one of the main fruit attributes that affect the marketability of Thompson seedless grapes. Yellowish berries are more desired by consumers especially at the beginning of the season. Consumers in many European countries have been demanding yellowish berries of “Thompson” seedless grapes. Ethrel was found to enhance the breakdown of chlorophylls and the formation of carotenes. How...

BACKGROUND This study identifies the percentage of opioids prescribed for compensated workplace conditions in Manitoba, Canada and whether Workers Compensation Board (WCB) status is associated with higher prescription opioid doses. METHODS Opioid prescriptions for WCB recipients were linked with databases housed at the Manitoba Center for Health Policy. Duration of continuous opioid prescript...

BACKGROUND Hazardous chemicals and their metabolites may accumulate in the body following repeated airborne exposures and skin contact. AIMS To estimate the contribution of skin absorption to total body burden of N,N-dimethylformamide (DMF) across a working week in two groups with similar levels of respiratory exposure but dissimilar skin contact. METHODS Twenty five workers in a synthetic ...

A binap-ligated copper iodide dimer embedded on a metal−-organic framework (MOF) was designed as an effective photoredox catalyst by Dan Li, Jian He, and co-workers in their Research Article (e202300233). Under visible-light irradiation, this heterogenized copper(I) complex promotes multiple iminyl radical-mediated reactions initiated N−O bond cleavage, with significantly enhanced photocatalyti...
