The lungs are covered by a thin serous layer (the visceral pleura). The pleura is then reflected on to the chest wall and pericardium (the parietal pleura). The lung hila 'connect' the visceral and parietal pleura. There is normally a small amount of fluid in the 'pleural space' between the parietal and visceral pleura, which lubricates movement between them. A pleural effusion occurs when the ...

While both these source books are more than adequate, Great Experiments in Biology is, by and large, the better of the two. Great Experiments contains 63 excerpts or complete papers and Classics of Biology, 75. Gabriel and Fogel have made the better selection and have organized their work better than Pi-Sufier, but the latter has written more adequate introductions to his various sections. Both...

Cladosporium chlorocephalum (= C. paeoniae) is a common, widespread leaf-spotting hyphomycete of peony (Paeonia spp.), characterised by having dimorphic conidiophores. During the season, one stage of this fungus causes distinct, necrotic leaf-blotch symptoms on living leaves of Paeonia spp. In late autumn, winter or after overwintering, a second morphologically distinct conidiophore type occurs...

We describe our experience with an apparently immunocompetent child presenting with pyrexia of unknown origin without focal signs. Investigations revealed lymphadenopathy at lung hila, mesentery, and porta hepatis. The child had received at least two months of empiric antituberculous therapy (ATT) before she came to us. A CT-guided biopsy revealed granulomatous inflammation. PAS stain showed ye...

In 2008 a group of former soldiers of the Israel Defense Force (IDF) sued the Ministry of Defense and others, claiming they had suffered from medical problems that resulted from an IDF medical experiment in which they had participated in the 1970s. There was no compelling medical evidence with respect to causal relationships between their participation in the experiment and their later medical ...
