Retinoids, vitamin A (retinol) and related metabolites, have been shown to be important in regulating cell growth and differentiation. We have shown that expression of the enzyme lecithin:retinol acyltransferase (LRAT), which converts retinol to retinyl esters, is reduced in several human carcinomas as compared with adjacent normal tissue from the same organs. The purpose of this research was t...

This report describes a case of granulomatous endometritis caused by coccidiosis in an immunologically uncompromised 63 year old patient. The glandular epithelium of the endometrium contained numerous intracytoplasmic cysts, corresponding to periodic acid Schiff positive and methenamine silver negative sporoblasts. The endometrial glands revealed reactive phenomena, such as eosinophilic and squ...

BACKGROUND AND AIMS Changes in number of trichomes and in composition and concentrations of their exudates throughout leaf development may have important consequences for plant adaptation to abiotic and biotic factors. In the present study, seasonal changes in leaf trichomes and epicuticular flavonoid aglycones in three Finnish birch taxa (Betula pendula, B. pubescens ssp. pubescens, and B. pub...

The morphological specifications play a substantial role in classification and breeding programs of various plant taxa. In the current study, some macro- and micro-morphological features of Salvia nemorosa, Salvia syriaca, Salvia frigida and Salvia virgata (three accessions), were investigated using scanning electron microscopy and image analysis program. The completely randomized design (CRD) ...

Introduction: The implantation is a complex procedure that involves many molecules. One of these molecules is integrin specially &alphav&beta3 which serves as receptor for components of extra cellular matrix to act as bridging molecules between the blastocyst and the endometrial surface during the implantation process. By blocking &alphav&beta3 interactions, the implantation can be impaired. ...
