The prevalence of dental fluorosis in a nonfluoridated area was determined and related to the reported fluoride ingestion histories of the children examined. A convenience sample of 543 schoolchildren in rural areas of Michigan was examined for fluorosis using the Tooth Surface Index of Fluorosis. Questionnaires that asked about previous use of fluorides were sent to parents of all children exa...

Background This work is intended to establish a relation between two diseases, medical and psychiatric, both of them considered public health issues – chronic hepatitis C and depression. Interferon has been a great progress for the chronic hepatitis C patients’ therapy, but the treatment is encumbered by the occurrence of depression on 3-57% of patients. The purpose of this work is to assess th...

The spin reversal of nanostructured Co/Pd multilayers by varying the number of repeats has been investigated quantitatively. The magnetization viscosity measurement and the direct observation of the time-dependent spin reversal patterns showed that their reversal behavior gradually changed from wall-motion dominant to nucleation dominant by increasing the number of repeats. Both the wall-motion...

A survey of 1329 relatives of 139 patients with coeliac disease demonstrated an overall increase of cancer deaths particularly in women, but this did not quite reach 5 percent significance in men. Evidence is insufficient to determine whether this was due to the occurrence of cancer in relatives with undetected coeliac disease or to the operation of independent factors.

Pneumopericardium is an uncommon complication of the neonatal transition period, occurring in 1.3 percent of premature neonates in intensive care settings. Its occurrence is usually associated with some type of barotrauma or respiratory intervention, such as endotracheal intubation or administration of continuous positive airway pressure, and is almost exclusively a problem for the premature in...

aflatoxin m1 (afm1) is an important mycotoxin frequently found in milk and dairy products. dairy products and colostrum may be contaminated by aflatoxin m1 when dairy cattle have fed with aflatoxin b1-contaminated feeds. this study was undertaken in a dairy farm around tehran province to determine the presence and level of aflatoxin m1 (afm1) in spray dried and lyophilized colostrum samples. in...

In this paper, we present a structural and statistical approach for texture classification. It can achieve with a higher accuracy rate comparing to the Spatial Gray Level Dependence (SGLD) method and Laws' method. Our method uses the previously proposed operator, the Surface-Shape operator (SS-operator), for describing topographic structure of texture images. The SS-operator describes shape of ...
