KL-6, a mucinous high-molecular weight glycoprotein, expressed on type II pneumonocytes, is elevated in the serum of patients with active interstitial pneumonia. Forty-seven patients with histologically confirmed sarcoidosis were analyzed by chest radiography, CT, 67Ga scintigraphy, BAL fluid (BALF), and serum KL-6. Serum KL-6 level was significantly elevated in radiographic type II (945 +/- 72...
KL-6 is a pulmonary epithelial mucin more prominently expressed on the surface membrane of alveolar type II cells when these cells are proliferating, stimulated, and/or injured. We hypothesized that high levels of KL-6 in epithelial lining fluid and plasma would reflect the severity of lung injury in patients with acute lung injury (ALI). Epithelial lining fluid was obtained at onset (day 0) an...
The receptor tyrosine c-Kit and its cognate ligand, c-Kit ligand (KL, stem cell factor, SCF), are involved in ovarian follicular development in several animal species. We studied the expression of KL and c-Kit using in situ hybridization and immunohistochemistry in donated human ovarian cortical tissue. The KL transcripts were expressed in granulosa cells of primary follicles, whereas the expre...
This study evaluated the levels of c-kit mRNA in goat follicles and the effects of kit ligand (KL) on the in vitro development of cultured preantral follicles. Preantral follicles isolated from goat ovarian cortex were cultured for 18 days in α-MEM(+) supplemented with KL (0, 50 or 100 ng/mL) in the absence or presence of follicle stimulating hormone (FSH). Real-time PCR showed that c-kit mRNA ...
“Kernel Logistic PLS” (KL-PLS), a new tool for classification with performances similar to the most powerful statistical methods is described in this paper. KL-PLS is based on the principles of PLS generalized regression and learning via kernel. The successions of simple regressions, simple logistic regression and multiple logistic regressions on a small number of uncorrelated variables that ar...
In decision making systems involving multiple classifiers there is the need to assess classifier (in)congruence, that is to gauge the degree of agreement between their outputs. A commonly used measure for this purpose is the Kullback-Leibler (KL) divergence. We propose a variant of the KL divergence, named decision cognizant Kullback-Leibler divergence (DC-KL), to reduce the contribution of the...
We consider the space of w-mixtures that are the set of finite statistical mixtures sharing the same prescribed component distributions. The geometry induced by the Kullback-Leibler (KL) divergence on this family of w-mixtures is a dually flat space in information geometry called the mixture family manifold. It follows that the KL divergence between two w-mixtures is equivalent to a Bregman Div...
French listeners tend to hear illegal utterance-initial /tl/ and /dl/ clusters as /kl/ and /gl/, respectively, when speech is produced by French speakers [1, 5]. We reexamined this phenomenon, once called “phonotactic perceptual assimilation,” in a cross-linguistic design using Modern Hebrew. In Hebrew, virtually all the obstruent-liquid clusters are permissible, including /dl, tl/. French and ...
