Yeast calmodulin (CaM) is required for the progression of nuclear division (Ohya, Y. and Y. Anraku. 1989. Curr. Genet. 15:113-120), although the precise mechanism and physiological role of CaM in this process are unclear. In this paper we have characterized the phenotype caused by a temperature-sensitive lethal mutation (cmdl-101) in the yeast CaM. The cmdl-101 mutation expresses a carboxyl-ter...

The histogenetic relationship amongst various dendritic cells of the dermis which may express markers including factor XIIIa (FXIIIa) or CD34 remains unclear. In this study we utilized a sensitive indirect immunoperoxidase staining technique to identify CD34 and FXIIIa, as well the monocyte/macrophage markers KP-1 and MAC 387 expression in a variety of cutaneous dermal tumors of mesenchymal ori...

an adult native cock (gallus gallus domesticus) referred to the aviary clinic with multiple different sizes of round dermal nodules. the bird died few days later, and was then submitted for further evaluation. macroscopic and microscopic examinations as well as a pcr test were done to identify type and cause of the tumor. in histopathological assessment of biopsy specimen, it consisted of inter...

Intelligent knowledge based system (IKBS) is developed for optimizing dry CNC turning process using Taguchi method, CNC Machine, EN19 steel as the work piece material, andCutting Insert. Tool wear and spindle loading which are the machining parameters, spindle speed, feed rate, and depth of cut, areoptimized through the intelligent knowledge based system (IKBS). The experimental CNC turning mac...

Spindle cell hemangioma is a benign vascular tumor presenting as multifocal red or bluish nodules on the distal limbs. We present a 57-year-old woman with five years history of multiple, soft, violaceous nodules on her hands. Pathologic study indicated spindle cell hemangioma.

In the Baltic clam Macoma balthica from the Gulf of Gdansk, neoplasia is considered as a serious epizootic linked to bad environmental conditions and high levels of pollutants. Previous research was focused on the diagnosis, prevalence, seasonality and histopathological characteristic of the cancer. This study is focused on electron microscopy analyses describing cell ultrastructure abnormaliti...

Background: The aim of this study was to assess effects of cysteamine as an anti-oxidant on rate of in vitro maturation of oocyte and determination of its effects on spindle size and shape. Methods: Pre-mature mice were primed with pregnant mare stimulating gonadotrophin (PMSG) and germinal vesicle (GV) stage oocytes were obtained 48 h after. The oocytes were cultured in tissue culture medium (...

The ?-axons supplying muscle spindle (MS) induce a particular pattern of activity in spindle Ia and II afferents on contraction. From a dynamic viewpoint, the Ia shows increasing spike rates, but II-afferents do not show any activity. For evaluation of nerve fiber activity, spike amplitude (SA) is suggested to measure it as well as its benefit of diagnosing clinical symptoms. This paper aims to...
