BACKGROUND Previous inconsistent results suggest that menstrual cycles may be disturbed by exposure to polychlorinated biphenyls (PCBs) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (DDE). METHODS Information on menstrual cycle characteristics were obtained by questionnaires, and PCB and DDE were measured in serum samples from a total of 1494 women from Greenland, Swedish fishermen's wiv...

Experiments were conducted to determine the ability of citrate to enhance the plant uptake of weathered 2,2-bis(p-chlorophenyl)1,1-dichloroethylene (p,p'-DDE) from soil. Plots containing three rows of clover, mustard, hairy vetch, or rye grass were constructed in soils containing p,p'-DDE. On 11 occasions, the rows of each crop received water or sodium citrate (0.005 or 0.05 M). For each crop, ...

To explore the role of DDE, the major and most persistent DDT derivative, in cancer etiology, we examined the association of the 1968 adipose DDE levels of population samples from 22 U.S. states with age-adjusted mortality rates between 1975 and 1994 for multiple myeloma; non-Hodgkin lymphoma (NHL); and cancer of the breast, corpus uteri, liver, and pancreas. Separate analyses were conducted by...

The aim of our study was to examine whether pre-natal exposure to dichlorodiphenyldichloroethylene (DDE) increases the risk of lower respiratory tract infections (LRTIs) and wheeze in infants. The study is based on a birth cohort of 1,455 mother-child pairs. Maternal serum concentrations of DDE, polychlorinated biphenyls (PCBs) and hexachlorobenzene (HCB) were measured during pregnancy. Parenta...

Differential evolution (DE) is a prominent stochastic optimization technique for global optimization. After its original definition in 1995, DE frameworks have been widely researched by computer scientists and practitioners. It is acknowledged that structuring a population is an efficient way to enhance the algorithmic performance of the original, single population (panmictic) DE. However, only...

Late last month the NEW ENGLAND JOURNAL OF MEDICINE (NEJM) published a study (by David J. Hunter) comparing the levels of DDE and PCBs in the blood of two groups of women, one group with breast cancer, the other without.[1] The Hunter study failed to find a positive relationship between breast cancer and DDE or PCBs in the blood. DDE is a breakdown product of the organochlorine pesticide DDT, w...

Intestinal absorption mechanisms of young calves change rapidly during the first 24 h postpartum and subsequently effect the absorption efficiencies of a wide range of compounds. This study was conducted to determine absorption efficiencies of (p,p'-dichlorodiphenyl)dichloroethylene (DDE), 2,2',4,4',5,5'-hexachlorobiphenyl (PCB-153), and 1,2,3,4,6,7,8,9-octachlorodibenzo-p-dioxin (OCDD) when ad...

All-Solid-State Batteries In article number 2300172, Ju Young Kim, Yong Min Lee, and co-workers present a dry pre-lithiation strategy for the graphite/silicon-based diffusion-dependent electrodes (DDEs) by simply introducing Li metal powder in DDE. The added uniformly continuously provides ions to active materials mitigates volume change of DDE during charge/discharge cycles, leading high-perfo...

BACKGROUND Although it is known that sperm aneuploidy contributes to early pregnancy losses and congenital abnormalities, the causes are unknown and environmental contaminants are suspected. OBJECTIVES Our goal was to evaluate associations between lifetime exposure to organochlorines, specifically dichlorodiphenyldicholorethylene (p,p´-DDE) and polychlorinated biphenyls (PCBs), and sperm aneu...
