در دهه های اخیر، تئوری سیستم های کنترل در بسیاری از موضوعات صنعتی، پزشکی و... مورد استفاده قرار گرفته است. بیماری دیابت یکی از موضوعات جدید و مورد توجه علم کنترل می باشد. برای بیماران دیابتی نوع اول، به دست آوردن نرخ تزریق مناسب انسولین به صورت اتوماتیک همواره موضوع مورد توجه پزشکان بوده است. هدف از کنترل و درمان دیابت، نگه داشتن گلوکز خون در حد طبیعی در بدن می باشد. در واقع، تعمیم بسیاری از کن...

BACKGROUND The association of DDT (dichlorodiphenyltrichloroethane) with breast cancer is controversial, but animal studies directly linking DDT to risk are lacking. Concerns with DDT reside in its environmental persistence, bioaccumulation in breast adipose tissue, and endocrine-disrupting actions. Whereas most attention has been focused on estrogenic congeners, we tested the cancer-inducing p...

Longitudinal studies have shown that early life exposure to dichlorodiphenyl dichloroethene (DDE) can lead to growth reduction during childhood and adolescence. In addition, DDE exposure has been linked to respiratory tract infections and an increased risk of asthma in children. Our aim was to understand the relationships between DDE exposure and pulmonary function in children, and, particularl...

Anticoccidial effects of the root bark of Dictamnus dasycarpus Turcz (Rutaceae) extract (DDE) were evaluated in chickens following oral infection with Eimeria (E.) tenella. Three-day-old chickens (n=30) were assigned to three groups (control, untreated, and DDE 0.1% treated). Chickens were fed a standard diet supplemented with or without DDE for 1 week prior to infection with E. tenella (10,000...

Dichlorodiphenyldichloroethylene (p,p'-DDE), the most persistent metabolite of dichlorodiphenyltrichloroethane (DDT), is still present in the human population. Both are present in the bone marrow of patients with bone marrow disorders, but thus far there are no studies that assess the capability of p,p'-DDE to affect myeloid cells. The aim of this study was to determine the effect of p,p'-DDE o...

Fish sexual development is sensitive to exogenous hormone manipulation, and salmonids have been used extensively as environmental sentinels and models for biomedical research. We simulated maternal transfer of contaminants by microinjecting rainbow trout (Oncorhynchus mykiss) and chinook salmon (Oncorhynchus tshawytscha) embryos. Fish were reared for 6 months and sexed, and gonads were removed ...

Polychlorinated biphenyls (PCBs), once used widely in transformers and other applications, and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (DDE), the main metabolite of the pesticide 1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane (DDT), are hormonally active agents. Changes in menstrual cycle functioning associated with PCBs and DDE, and increased odds of spontaneous abortion associated with DD...

BACKGROUND Developmental defects of enamel (DDE) may be influenced by health problems and illness in children. The aim of the study was to identify the main characteristics of birth (delivery) and adverse medical conditions during the first month of life that may be related to DDE in permanent teeth. METHODS 1000 schoolchildren between the ages of 9 and 11 years were selected for this cross-s...
