TL;DR: In this paper, the authors suggest that the palpation of what appears to be a normal-sized ovary for a patient three to five years postmenopausal is indicative of an ovarian tumor and should be investigated.

TL;DR: The transformation of the P. cynomolgi oocyst into definitive sporozoite forms occurs 8–10 days after an infective blood meal by Anopheles, stephensi mosquitoes.
Abstract: SYNOPSIS. The transformation of the P. cynomolgi oocyst into definitive sporozoite forms occurs 8–10 days after an infective blood meal by Anopheles, stephensi mosquitoes. Vacuolization divides the oocyst cytoplasm into sporoblast sub-units from which sporozoites bud. The role of sporoblast nuclear and cytoplasmic components in the complex differentiative process is discussed.

TL;DR: It is concluded that diagnoses such as basal cell hyperplasia, stratification and flattening, and squamous metaplasia should be clearly differentiated and application of such criteria may result in more meaningful clinicopathologic correlations.
Abstract: Alterations in rat bronchial epithelium produced by 3-methylcholanthrene-coated steel pellets and those resulting from uncoated steel pellets were studied by light and electron microscopy. Exposure to uncoated pellets resulted in increased cell interdigitations, moderate stratification and flattening, and incomplete loss of cilia and polarity. In contrast, carcinogen-coated pellets produced complete loss of cilia and cell polarity and severe stratification. Increased cell interdigitations and desmosomal junctions as well as abundant cytoplasmic filaments, keratohyalin granules, and “membrane-coating granules” were also observed. Thus, only contact with a carcinogen produced cells capable of keratin synthesis. We conclude that diagnoses such as basal cell hyperplasia, stratification and flattening, on the one hand, and squamous metaplasia, on the other, should be clearly differentiated. The diagnosis of squamous metaplasia should be made only in the presence of clear evidence of keratin synthesizing cells. Application of such criteria may result in more meaningful clinicopathologic correlations.

TL;DR: Although pyrimethamine does not produce a consistent ultrastructural change, agent 49808 leads to swelling and a decrease in matrix density of mitochondria, the net effect of both agents upon oocyst development is the same although the postulated mechanisms of action are different.

TL;DR: Falsely assuming that the data is Gaussian produces errors in classifying patients, and in statistical inferences drawn from parametric tests, in quality control programs in automated clinical chemistry systems.
Abstract: Data, obtained in quality control programs in automated clinical chemistry systems are often not normally distributed. Falsely assuming that the data is Gaussian produces errors in classifying patients, and in statistical inferences drawn from parametric tests.
