It has been shown recently that the acinus is only partially efficient in normal conditions. This is due to a "screening effect" governed by the relative values of the oxygen diffusivity and the membrane resistance as well as design and size of the acinus. These effects depend on the fraction of the acinus in which gas transport is governed by diffusion, then on the location of the convection-d...

BACKGROUND There is currently some uncertainty about the effectiveness of screening outside the established core ages of 30 to 60. We audited the screening histories of cervical cancers and conducted a case-control evaluation of the effectiveness of organized screening in different ages. METHODS Screening histories for 1,546 cervical cancer cases and 9,276 age-matched controls were derived by...

hydroalcoholic extract (70% ethanol extract) of tubers of momordica tuberosa cogn. (cucurbitaceae) was subjected to preliminary phytochemical screening by qualitative tests. nitric oxide scavenging activity was performed by griess reagent method. and nephroprotective activity was assessed in gentamicin, cisplatin and paracetamol induced renal damage in wistar rats (150-200 g) by standard method...

Objectives: Ongoing randomized controlled screening trials for prostate cancer have not shown a beneficial effect on prostate cancer mortality reduction yet. A large number of observational (non-randomized) studies on prostate cancer screening have been published with contradictory outcome. This paper reviews the current case-control studies. Methods: Seven case-control studies of screening for...

OBJECTIVES Breast cancer is a histological, morphological and molecular heterogenous disease. Like clinical outcomes and prognoses of different subtypes, etiologies might also be different. Therefore, epidemiologic risk factors like sociologic, demographic, antropometric, reproductive, and menstrual factors can be considered as an entity reflected in tumor features. This study was planned to ex...
