Authors: Graham Peers, Thuy B. Truong, Elisabeth Ostendorf, Andreas Busch, Dafna Elrad, Arthur R. Grossman, Michael Hippler & Krishna K. Niyogi Light is necessary for photosynthesis, but its absorption by pigment molecules such as chlorophyll can cause severe oxidative damage and result in cell death. The excess absorption of light energy by photosynthetic pigments has led to the evolution of protective mechanisms that operate on the ... Full story

To estimate the risk of endometrial cancer in all Finnish postmenopausal women using various forms of estradiol-progestin therapy. METHODS: All Finnish women (aged more than 50 years) who had used estradiol-progestin therapy in 1994-2006 for at least 6 months (n=224,015) were identified from the national medical Reimbursement Registry and linked to the Finnish Cancer Registry. A total of 1,364 type I and 38 type II endometrial ... Full story

(World Journal of Gastroenterology) A research team from China developed short hairpin RNA against heparanase (HPA), and determined its effects on HPA expression and the malignant characteristics of gastric cancer cells. Their study showed that stable knockdown of HPA can efficiently decrease the invasiveness, metastasis and angiogenesis of human gastric cancer cells. In contrast, stable knockdown of HPA does not affect the cell proliferation. (Source: ... Full story

UroToday.com - The purpose of the clinical study was to evaluate whether quantitative parameters of tumor vascularisation assessed by DCE-MRI enable the determination of the morphologic grading of renal cell carcinomas non-invasively. Our prospective study included 21 patients suspected of having renal cell carcinoma with a mean age of 61.5 years. Go to ... Full story

CONCLUSION. Patients presenting with nontraumatic abdominal pain imaged using 64-MDCT with isotropic reformations had similar characteristics for the diagnosis of appendicitis when IV contrast material alone was used and when oral and IV contrast media were used.
