BACKGROUND Few studies on how to diagnose pulmonary neuroendocrine tumors through morphometric analysis have been reported. In this study, we measured and analyzed the characteristic parameters of pulmonary neuroendocrine tumors using an image analyzer to aid in diagnosis. METHODS Sixteen cases of typical carcinoid tumor, 5 cases of atypical carcinoid tumor, 15 cases of small cell carcinoma, ...

BACKGROUND AND PURPOSE the purpose of this study was to identify significant morphological and hemodynamic parameters that discriminate intracranial aneurysm rupture status using 3-dimensional angiography and computational fluid dynamics. METHODS one hundred nineteen intracranial aneurysms (38 ruptured, 81 unruptured) were analyzed from 3-dimensional angiographic images and computational flui...

Stimulation of the adrenal cortex by the "stress" of illness is now taken for granted. Numerous publications have described changes in adrenal cortical histology in particular diseases, and at least one author' has attempted a general study of the adrenal cortex in an autopsy population. Even so little attention is paid the adrenal cortex in the average autopsy performed by the average patholog...

Apoptosis is characterised by a series of typical morphological features, such as shrinkage of the cell, fragmentation into membrane-bound apoptotic bodies and rapid phagocytosis by neighbouring cells. This paper reviews the current knowledge on the molecular mechanisms of apoptosis as they relate to the morphologic hallmarks and their implications for the detection of apoptosis in cardiac tiss...

The purpose of the study was to ascertain the basic morphologic and kinematic characteristics of elite sprinters. The sample included 24 sprinters, with times over a 100 m distance between 10.21 s and 11.19 s. Morphologic characteristics of the sprinters were measured with a test battery of 17 measures, obtained according to the methodology prescribed by the International Biologic Programme (IB...

The author describes how anatomic findings and the differing goals of male and female patients, as well as other considerations, have altered his technique for surgical correction of the aging midface. (Aesthetic Surg J 2001;21:349-353.).

Studies of fetal hemoglobin and bone marrow ultrastructure were performed on a patient with a recently described syndrome consisting of lymphosarcoma, short stature, defective cellular Immunity, hypogammaglobulinemia, and mosaicism for a marker chromosome. Abnormalities of the erythroid cells, including multinucleated erythroblasts, nuclear bodies, megaloblasts, and frayed cytoplasm, were seen ...

Regularization is an well-known technique for obtaining stable solution of ill-posed inverse problems. In this paper we establish a key relationship among the regularization methods with an edge-preserving noise filtering method which leads to an efficient adaptive regularization methods. We show experimentally the efficiency and superiority of the proposed regularization methods for some inver...

Experiments were conducted on soft-tissue and bone preparations to determine the morphological characteristics of angle grinder injuries. The grinding effect of the rotating cutting-off wheel causes severances with local loss of tissue, resulting in tool-specific wound features. Superficial skin notches and (incomplete) severances of bony structures are of particular significance. Mutual trace ...
