Bilateral anophthalmia was discovered in a male rat (No. 1) and unilateral anophthalmia was found in the left eye of two female rats (Nos. 2 and 3) derived from a Fischer 344 inbred colony. One male rat (No. 4), a littermate of No. 3, had externally normal eyes, but his left eye had severe retinal atrophy, which was detected by ophthalmoscopy. The eyelids in both eyes of No. 1 and in the left e...

Background Nutrient foramen is an opening into shaft of humerus which gives passage to the blood vessels of medullary cavity. The knowledge of nutrient foramen is important in surgical procedures like bone grafting and more recently in microsurgical vascularized bone transplantation. Objective To determine the number, location and direction of nutrient foramen and whether the nutrient foramens ...

Sternal foramina may pose a great hazard during sternal puncture, due to inadvertent cardiac or great vessel injury. They can also be misinterpreted as osteolytic lesions in cross-sectional imaging of the sternum. On the other hand, variant xiphoid morphology such as bifid, duplicated, or trifurcated may be mistaken for fractures during imaging. The distribution of these anomalies differs betwe...

A common feature of the mammalian septin gene family is complex genomic architecture with multiple alternate splice variants. Septin 9 has 18 distinct transcripts encoding 15 polypeptides, with two transcripts (SEPT9_v4 and v4*) encoding the same polypeptide. We have previously reported that the ratio of these distinct transcripts is altered in neoplasia, with the v4 transcript being the usual ...

A prospective blind comparison was completed between duplex sonography and angiography of the vertebral arteries. Thirty-two vertebral arteries were studied for direction of flow, degree of origin plaque or stenosis, Doppler characteristics, and vessel size. The vertebral arteries were reliably identified by imaging their course from the subclavian artery into the transverse foramina and by ide...

We describe a patient who developed involuntary, painless, dystonic contraction of the toes of the right foot on standing or walking. The development of this abnormal movement had been preceded by sensory disturbance on the soles of both feet, triggered by dorsiflexion of the feet. Examination showed that weight bearing on the right foot and walking brought on clawing of the toes of the right f...

PURPOSE To investigate by means of CBCT the presence of lingual foramina and their bony canals in the midline of the mandible and to describe their anatomical characteristics. MATERIALS AND METHODS CBCT examinations of 36 patients were carefully examined in the median region of the mandible in order to detect the lingual foramina and their corresponding vascular canals. Their presence, number...
