In vertebrates the microtubule-associated proteins MAP6 and MAP6d1 stabilize cold-resistant microtubules. Cilia and flagella have cold-stable microtubules but MAP6 proteins have not been identified in these organelles. Here, we describe TbSAXO as the first MAP6-related protein to be identified in a protozoan, Trypanosoma brucei. Using a heterologous expression system, we show that TbSAXO is a m...

introduction: the ectopic ciliated cyst is a rare non-odontogenic cyst which occurs as a delayed complication after maxillary sinus radical surgery; this lesion emerges due to the destruction of the sinus mucosa during the surgery and entrapment of the respiratoryepitheliumin the region. this lesion has been observed in very rare cases following genioplasty and bimaxillary orthognathic surgery....

The locomotory behaviour of ciliated protozoa results from the activity of the cell's cilia. The major variables in the protozoan's ciliary activity are the orientation of the effective stroke and the beating frequency. Ciliary orientation as used here is the direction of ciliary beat, or more specifically, the direction of the effective or power stroke. The effective stroke is defined as that ...

NBREEDING degeneration has been observed in many higher plants and animals I and its physical basis and its bearing on the genetic economy of these organisms have been widely discussed (GOWEN 1952; LERNER 1954). While some genetic problems such as gene action, mutagenesis and genetic recombination have been actively and profitably pursued with microorganisms, relatively little work on inbreedin...

On palpation, sub-mental bony spur was felt. The defect was associated with limitation of neck extension. Surgery was offered. At operation the extent of the sinus was about 4-6mm. The skin defect along with its cranial and caudal lesions was excised. The surgical wound was closed with multiple z-plasties (Fig. 2). The postoperative recovery was uneventful. Histopathology of the specimen showed...
