Two articles in the March 2014 issue of EHP were of particular interest to exposure scien tists and phthalate researchers. The news article by Nicole (2014) emphasized the importance of the vaginal epithelium as an exposure route for chemicals in per­ sonal care products and the general lack of research on this exposure route. However, the article did not mention adult toys as a pos­ sible sour...

Previous studies on the calcium metabolism of epidermis undergoing carcinogenesis (@2,10, 11) have suggested the possibility that the action of one or more calcium-binding substances may ac count for the decreased calcium content in hyper plastic epidermis and in a squamous-cell carcinoma. The present investigation has been devoted to a study, in normal and cancerous tissues of the mouse, of th...

Honeybees, Apis mellifera, gradually increase their rate of forage uptake as they gain foraging experience. This increase in foraging performance has been proposed to occur as a result of learning; however, factors affecting flight ability such as changes in physiological components of flight metabolism could also contribute to this pattern. Thus, the purpose of this study was to assess the con...

The tumor microenvironment is comprised of diverse stromal cells that contribute towards tumor progression. As a result, there has been a growing interest in the role of bone marrow derived cells (BMDCs) in cancer progression. However, the role of BMDCs in prostate cancer (PCa) progression still remains unclear. In this study, we established GFP bone marrow transplanted TRAMP and MUN-induced pr...

PURPOSE To evaluate food intake of patients with urinary lithiasis and idiopathic hypercalciuria (IH). MATERIALS AND METHODS Between August 2007 and June 2008, 105 patients with lithiasis were distributed into 2 groups: Group 1 (n = 55)--patients with IH (urinary calcium excretion > 250 mg in women and 300 mg in men with normal serum calcium); Group 2 (n = 50)--normocalciuria (NC) patients. I...

STUDY OBJECTIVE To evaluate the efficacy and safety of caffeine citrate for treatment of apnea of prematurity. DESIGN Multicenter, parallel, randomized, double-blind, placebo-controlled trial with open-label rescue. SETTING Nine neonatal intensive care units. PATIENTS Eighty-five infants, 28-32 weeks postconception and 24 hours or more after birth who had six or more apnea episodes within...

Ochratoxin A (OTA) is a mycotoxin which is a common contaminant in grains during storage. Aspergillus ochraceus is the most common producer of OTA. Essential oils play a crucial role as a biocontrol in the reduction of fungal contamination. Essential oils namely natural cinnamaldehyde, cinnamon oil, synthetic cinnamaldehyde, Litsea citrate oil, citral, eugenol, peppermint, eucalyptus, anise and...

1. Our results show clearly that the Hofmeister series is not the correct expression of the relative effect of ions on the swelling of gelatin, and that it is not true that chlorides, bromides, and nitrates have "hydrating," and acetates, tartrates, citrates, and phosphates "dehydrating," effects. If the pH of the gelatin is taken into considertion, it is found that for the same pH the effect o...

IT is often stated that the addition of a citrate to milk prevents clotting by rennin because an un-ionised calcium citrate is formed, thus removing the calcium ions from solution, these ions being considered essential for the clotting process. The prevention of the clotting of blood by citrates is explained in the same way. It is not the purpose of this paper to discuss the clotting phenomenon...
