With the help of this system, two known synthetic

polyamines-alpha-difluoromethylorni-thine (DFMO) and methylglioxalbis(guanylhydrason) (MGBG)-as well as four new synthetic analogues difenylcontaining amines (DFCA-1-DFCA-4) with molecular weights of 725.5 (DFCA-1), 755.5 (DFCA-2), 655.5 (DFCA-3), and 681.5 Da (DFCA-4) were tested. In this biotest system, DFMO (0.1-400 mu M) did not reveal functional activity, whereas for MGBG a cytotoxic effect GF120918 cell line was registered (100-200 mu M). DFCA-1, DFCA-2, and DFCA-4 had a similar effect at concentrations of 10 mu M and higher; DFCA-3, at a concentration of 50 mu M and higher. Thus, DFCA-1 has a higher level of antiproliferating activity and may be considered as the most potent cytostatic agent.”
“This study reports the frequency of aspirin resistance and its correlation with clinical and biochemical parameters among 280 healthy Turkish volunteers (179 men, 101 women) who were taking 100 mg of aspirin 7 days or more. Aspirin resistance was detected BI2536 by optical platelet aggregometry, using adenosine diphosphate and arachidonic acid, and defined as a mean aggregation of 64% or more with 5 mu M adenosine diphosphate and a mean aggregation of 20% or more with 0.5-mg/mL arachidonic acid. Of the study population, 27.5% (26 women [25.5 %] and 51 men [28.5 %]) were aspirin resistant. The current findings indicate that aspirin resistance is an important and

real laboratory diagnosis given its frequency of 27.5% in the study population. These results of this large trial evaluating the frequency of aspirin resistance in healthy subjects indicate that aspirin resistance

should be diagnosed so that individuals with no response can receive alternative or additional antiplatelet therapy.”
“Purpose: To examine the role of friends as caregivers of people selleck chemical with terminal illness.

Method: Piloted questions were included in the 2001-2007 random face-to-face annual health surveys of 23 588 South Australians on the death of a loved one, caregiving provided, and characteristics of the caregiver and deceased individual. The survey was representative of the population by age, gender, and region of residence. Analyses focused on friends of the deceased loved one, providing daily or intermittent ‘hands on’ care. Logistic regression assessed predictors of home death.

Results: Daily ‘hands on’ carers were much more likely to be female and aged between 55 and 64; there was also a younger (< age 45) cohort of intermittent ‘hands on’ caregivers. When friends were carers, the deceased was more frequently younger (< age 65) and had cancer (p <= 0.001). Almost a third of caregiving friends were actively involved in care for > 12 months. Home deaths were more frequent (32%, p = 0.014) when friends were carers, and the rate of palliative care use was higher than when family/others provided care (70 vs 61%). Regression analyses confirmed friends as caregivers as a predictor of home death (OR 1.73: 95%, CI 1.15-2.87).
