background: in traditional medicine zingiber officinale used to regulate female menstural cycle and treat male infertility. recent studies have suggested the possible role of ginger extract in improving the testicular damage of busulfan. objective: the aim of this study was to evaluate the effects of zingiber officinale on the sperm parameters, testosterone level and the volume of the testes an...

The most reliable method for estimation of mean glomerular volume (MGV), the disector/Cavalieri method, is technically demanding and time consuming. Other methods suffer either from a lack of precise correlation with the gold standard or from the need for a large number of glomeruli in the sample. Here, a new method (the 2-profile method) is described; it provides a reliable estimate of MGV by ...

OBJECTIVE To assess the clinical feasibility and the accuracy of two pragmatic methods in comparison with a conventional computer based method of measurement of masses from CT. METHODS Nineteen CT scans of 11 patients with severe head injury, showing 34 traumatic lesions, were examined. The volume of every lesion was digitally measured, then a panel of three examiners independently repeated t...

We use Cavalieri’s principle to develop a novel integration technique which we call Cavalieri integration. Cavalieri integrals differ from Riemann integrals in that non-rectangular integration strips are used. In this way we can use single Cavalieri integrals to find the areas of some interesting regions for which it is difficult to construct single Riemann integrals. We also present two method...

OBJECTIVE To determine if there is an association between fatty diet induced obesity and spleen enlargement by means of Cavalieri principle, unbiased stereological method and light microscopic examination. METHODS In this study, we used 16 adult female Sprague Dawley rats, weighing between 150-200 g. All animals were obtained from the Ataturk University Experimental Research and Applying Cent...

OBJECTIVE The Cavalieri principle was applied to consecutive pathology sections that were photographed at the same magnification and used to estimate tissue volumes via superimposing a point counting grid on these images. The goal of this study was to perform the Cavalieri method quickly and practically. MATERIALS AND METHODS In this study, 10 adult female Sprague Dawley rats were used. Brain...

Automated method for exchange transfusion Sir, In their report (Archives, 1972, 47, 815) M. G. Philpott and A. Banerjee presented a technique of exchange transfusion based on the use of a Holter infusion pump with two channels connected to umbilical vein and artery. In 1971 we (Garofalo, Minerva, and Baltieri, 1971) described a method of exchange transfusion by means of Holter microinfusion rol...

Geometric and stochastic representations are derived for the big class of p-generalized elliptically contoured distributions, and (generalizing Cavalieri?s and Torricelli?s method of indivisibles in a non-Euclidean sense) a geometric disintegration method is established for deriving even more general star-shaped distributions. Applications to constructing non-concentric elliptically contoured a...

Bonaventura Cavalieri has been the subject of numerous scholarly publications. Recent students of Cavalieri have placed his geometry of indivisibles in the context of early modern mathematics, emphasizing the role of new geometrical objects, such as, for example, linear and plane indivisibles. In this paper, I will complement this recent trend by focusing on how Cavalieri manipulates geometrica...

Objective: Intracerebral haemorrhages account for approximately 20% of all strokes and have higher morbidity mortality, nearly 60% patients die within a year, the survivors live disabled. The volume intracerebral haemorrhage has strong association with unfavourable outcome; therefore, fast accurate measurement is crucial clinical decision making. This study aimed to compare ellipsoid methods Ca...
