OBJECTIVE In this article we present a simplified algorithm-based approach to the thickening of the small and large bowel wall detected on routine computed tomography (CT) of the abdomen. BACKGROUND Thickening of the small or large bowel wall may be caused by neoplastic, inflammatory, infectious, or ischaemic conditions. First, distinction should be made between focal and segmental or diffuse...

Postsystolic shortening and thickening of ischemic and postischemic myocardium are wellrecognized phenomena, but their significance is controversial. To discover whether postsystolic shortening and thickening might represent an active process and to establish their place as possible predictors of functional recovery during and after recovery from ischemia, we examined correlations in severely i...

BACKGROUND Although mucosal thickening is the most common radiographic finding observed regarding sinus pathology, the knowledge regarding its clinical significance on the outcomes of dental implants and grafting in the maxillary sinuses is still limited. We hypothesized that mucosal thickening would not alter the predictability for sinus floor augmentation and dental implant placement. The pur...

A novel shear thickening suspoemulsion is formulated and studied with a new rheo-microscope instrument. The experimental fluid system is comprised of a immiscible blend of Newtonian, low molecular weight poly(dimethylsiloxane) and a shear thickening suspension of colloidal silica in poly(ethylene glycol). The blend is studied as a function of composition where phase inversion is evident at low ...

Left ventricular (LV) thickening can be due to hypertrophy (concentric, asymmetric, eccentric) or remodelling (concentric or asymmetric). Pathological thickening may be caused by pressure overload, volume overload, infiltrative disorders, hypertrophic cardiomyopathy, athlete's heart or neoplastic infiltration. Magnetic resonance imaging (MRI) plays an important role in the comprehensive evaluat...

Cortical microtubules participate in the deposition of patterned secondary walls in tracheary element differentiation. In this study, we established a system to induce the differentiation of tracheary elements using a transgenic Arabidopsis (Arabidopsis thaliana) cell suspension stably expressing a green fluorescent protein-tubulin fusion protein. Approximately 30% of the cells differentiated i...

BACKGROUND AND PURPOSE Imaging of patients with a clinical diagnosis of mandibular osteoradionecrosis (ORN) is often performed to support that clinical suspicion, evaluate the extent of the disease, or exclude coexistent tumor recurrence. The purpose of our study was to describe the clinical, MR imaging, and CT features of five patients with mandibular ORN associated with prominent soft-tissue ...

Ischemia impairs blood supply to the brain, and reperfusion is important to restore cerebral blood flow (CBF) and rescue neurons from cell death. However, reperfusion can induce CBF values exceeding the basal values before ischemia. This hyperemic effect has been associated with a worse ischemic brain damage, albeit the mechanisms that contribute to infarct expansion are not clear. In this stud...

Osteoid osteoma is a common benign osteogenic bone neoplasm characterized histologically by increased osteoid tissue formation with an intracortical nidus surrounded by cortical thickening and vascular fibrous stroma and sclerosis. The clinical presentation classically includes severe nocturnal pain that is improved with nonsteroidal anti-inflammatory drugs. Younger men (second and third decade...

AIMS To test the hypothesis that fragments of platelet thrombi and vascular endothelium are incorporated into the walls of small cerebral vessels in systemic lupus erythematosus (SLE). METHODS Six varied necropsy cases of central nervous system (CNS) SLE and 15 controls were studied. The controls were selected to represent a wide range of diseases in which the cerebral circulation is compromi...
