Stumps and knotwood of Norway spruce (Picea abies) are valuable sources wood extractives. Although lignans from have already been utilized in value-added products, the behavior valorization stump-derived extractives less studied. In this study, composition lipophilic hydrophilic extractives, particularly lignans, various stump samples (stump bottom, heart, crushed samples) stored outside were L...

We investigated whether the use of vascularized peripheral nerve grafts on the optic nerve stump enhances axonal regeneration of retinal ganglion cells compared with isolated nonvascularized grafts. The rat median nerve was microsurgically sutured with its supplying artery and vein to the optic nerve stump. The number of retinal ganglion cells with regenerating axons was evaluated by retrograde...

Giant cell tumor (GCT) involving distal ulna being rare with reported rate of 0.45-3% of all GCT cases; the literature has only sporadic cases reported. Various treatment options have been proposed, and dilemma exist whether to do resection alone or resection combined with stabilization or reconstruction. Also, there is no conclusive evidence regarding the method of stabilization or reconstruct...

The stump of an occluded middle cerebral artery (MCA) is a rare but important aneurysm mimic. A 57-year-old male was admitted due to recurrent onset of transient ischemic attack. Computed tomography angiography (CTA) and digital subtraction angiography (DSA) showed a total obstruction in the right MCA with moyamoya phenomenon at distal trunks and a protruding lesion in the left MCA bifurcation....

Debilitating stump pain following amputation surgery is a major problem when it affects the patient's quality of life, often making the patient totally dependent on others for their day-to-day care. Attempts have been made to treat those patients through pharmacological, psychological, and physical therapies, but in many cases these fail to relieve the pain. This article focuses on three patien...

Smooth muscle tumors (SMTs) typically fall under either benign leiomyoma or malignant leiomyosarcomas based on histologic characteristics. SMTs that cannot be diagnosed as are then labeled smooth of uncertain potential (STUMP). A 31-year-old male presented with the right abdominal pain for 6 months. Imaging showed an enhancing soft-tissue mass arising from renal vein. pre-operative biopsy confi...

A sand-casting technique for trans-tibial sockets was applied to 28 amputees, and the prosthetic fit observed through transparent check sockets. The results were better than historical reports of fittings with plaster of Paris casting by qualified prosthetists. The fit was consistently and evenly larger than the stump, but total contact could be achieved by applying three (two to five) stump so...

In the context of forest modeling, it is often reasonable to assume a mukiplicative heteroscedastic error structure to the data. Under such circumstances ordinary least squares no longer provides minimum variance estimates of the model parameters. Through study of the error structure, a suitable error variance model can be specified and its parameters estimated. This error model is used to cons...
