BACKGROUND AND PURPOSE The branches of the LSA are the main causative arteries for lacunar infarction, though the vascular changes are largely unknown. Herein, we examined the correlation of LSA imaging findings in patients with lacunar infarction compared with controls by using FSBB-MRA. MATERIALS AND METHODS Fifteen patients (9 men, 6 women; mean age,(More)
Damage to the paraspinal muscle after various lumbar back surgery procedures was evaluated by measuring the paraspinal muscle thickness preoperatively and postoperatively in 89 patients, 61 males and 28 females. There were 42 single interlaminar level procedures (SL group), 13 multiple interlaminar level procedures (ML group), and 34 posterolateral fusion(More)
OBJECT Thrombomodulin is a thrombin receptor on vascular endothelial cells that is highly expressed when these cells are injured, and it has anticoagulating activity. The authors investigated thrombomodulin expression to clarify why chronic subdural hematomas (CSDHs) continue to grow slowly, like a tumor, and are liquefied. METHODS Burr hole craniotomy(More)
In this paper, we propose an implementation method for specifications of distributed systems described in a subclass of LOTOS where operators such as choice and disabling can be used in combination with multi-rendezvous among remote processes. A LOTOS specification with the assignment of each process to a node is implemented as a set of executable codes(More)
A 53-year-old male presented with a rare dorsally sequestrated thoracic disc herniation manifesting as acute low back pain and weakness. He had no history of trauma. Magnetic resonance (MR) imaging demonstrated a mass at T10-11 intervertebral level connected with the T-10 disc. Axial MR imaging showed the mass had surrounded and compressed the dural sac(More)
Petri nets have been used to model many systems like computer systems, knowledge based system, manufacturing systems etc. But these Petri nets do not have sufficient power to represent and handle approximate and uncertain information. Hence Fuzzy Petri Net (FPN) are defined to model systems such as robot systems having lower level of operations. The study(More)
In this paper, we propose an implementation method for specifications of distributed systems described in a subclass of LOTOS where operators such as choice and disabling can be used in combination with multi-rendezvous among remote processes. Each process in a LOTOS specification is assigned to a node. The processes assigned to a node are transformed into(More)
A 24-year-old male presented with headache. He had been treated with antituberculous drugs for 19 months. MRI revealed 4 intracranial Gd-DTPA enhanced lesions surrounded by massive edema in the right frontal, both occipital and left basal ganglionic regions. Digital subtraction angiography showed no tumor stain. Two procedures for tumor resection were(More)
We report a 54-year-old man with progressive proximal muscle atrophy and gynecomastia. The patient had an insidious onset of weakness in his lower extremities at age 14, in that he noted a difficulty in standing up from a chair. Soon after he noted some difficulty in climbing up stairs. At age 35, he noted weakness in his arms; his weakness slowly(More)
We report a 46-year-old female who presented progressive ophthalmoplegia and limb weakness. She was well until the age of 15 years when there was an onset of bilateral deafness. She became completely deaf by 20 years of age. She noted an onset of weakness in her legs when she was 27-years-old and of ptosis at 34 years of age. She was admitted to our(More)
