In addition to senile plaque and neurofibrillary tangles, granulovacuolar degeneration is a hallmark of Alzheimer's disease. A number of tau kinases, such as c-jun N-terminal kinase (JNK), glycogen-synthase kinase-3β (GSK3β), and casein kinase 1 (CK1), have been reported to be markers of granulovacuolar degeneration. In addition, cyclin-dependent kinase 5 (CDK5), which phosphorylates tau, has b...
Axonal degeneration occurs in multiple neurodegenerative disorders of the central and peripheral nervous system. Although the underlying molecular pathways leading to axonal degeneration are incompletely understood, accumulating evidence suggests contributions of impaired mitochondrial function, disrupted axonal transport, and/or dysfunctional intracellular Ca(2+)-homeostasis in the injurious c...
Our recent study detected the expression of a tissue renin–angiotensin system (tRAS) in human intervertebral discs (IVDs). The present sought to investigate impact angiotensin II receptor type 1 (AGTR1) antagonist losartan on nucleus pulposus (NP) cell inflammation and degeneration induced by tumor necrosis factor-α (TNF-α). Human NP cells (4 donors; Pfirrmann grade 2–3; 30–37-years–old; male) ...
Macular degeneration or often called Age-related Degeneration (AMD) is a degenerative disease that attacks the center of vision in retina, namely macula. In an effort to prevent progression AMD, consuming antioxidants has been shown inhibit AMD development process. Although currently there no definite number sufferers Indonesia, it estimated will continue increase. Carotenoids are one antioxida...
PURPOSE To study MR images for atrophic changes in the calcarine area resulting from retinal degeneration. METHODS MR images from nine patients with retinal degeneration confirmed by ophthalmologic examination and from 30 healthy volunteers were reviewed. The causes of retinal degeneration were hereditary pigmentary degeneration of the retina (four patients), high myopia (two patients), and c...
Matching fields were introduced by Sturmfels and Zelevinsky to study certain Newton polytopes, more recently have been shown give rise toric degenerations of various families varieties. Whenever a matching field gives degeneration, the associated polytope variety coincides with polytope. We combinatorial mutations, which are analogues cluster mutations for polytopes show that property giving de...
Local axon degeneration is a common pathological feature of many neurodegenerative diseases and peripheral neuropathies. While it is believed to operate with an apoptosis-independent molecular program, the underlying molecular mechanisms are largely unknown. In this study, we used the degeneration of transected axons, termed "Wallerian degeneration," as a model to examine the possible involveme...
objective(s): we investigated the histopathological effects of metamizole sodium (ms) on the sciatic nerve. materials and methods: this study was performed using 48 adult male wistar albino rats. ten groups were constituted with 6 rats in each group. ms injection into the sciatic nerve (group 1), ms injection into the muscle [group 3 (50 mg/kg, 0.4 ml) and group 5 (50 mg/kg, 0.8 ml)], ms injec...
OBJECTIVE Pfirrmann disc degeneration grade is one of morphologic disc degeneration grading system and it was reliable on routine T2-weighted magnetic resonance (MR) images. The purpose of this study was to evaluate the agreement of Pfirrmann disc degeneration grade, and check the alternative technique of disc degeneration grading system. METHODS Fifteen volunteers (4 medical doctors related ...
