BACKGROUND Nephrotic syndrome is caused by a variety of glomerulopathy. The current study investigated the renal histopathological spectrum of patients with nephrotic syndrome who received a renal biopsy in our department within the last 15 years. METHODS One thousand five hundred and twenty-three consecutive patients (≥14 years old at renal biopsy) with nephrotic syndrome were recruited. Pat...

BACKGROUND Nephrotic patients are prone to atherosclerosis in consequence of frequent exposures to hyperlipidemia, hypertension, and immunosuppressive drugs. OBJECTIVES We studied the carotid parameters as early indicators of atherosclerosis in children with nephrotic syndrome. METHODS Between 2008 and 2011, 51 children with history of nephrotic syndrome enrolled in the study. The inclusion...

Oedema is a common clinical manifestation of nephrotic syndrome. However, the pathophysiological mechanism of sodium retention in nephrotic syndrome has been intensely debated for decades. Several clinical and experimental observations argue against the classic or "underfill" hypothesis of oedema formation in nephrotic syndrome. In many patients, oedema formation in nephrotic syndrome is due to...

Thromboembolism is a rare complication of primary nephortic syndrome. Both venous and arterial thrombosis might occur in steroid responsive and steroid resistant nephrotic syndrome. This is the report of an infant with nephrotic syndrome and renovascular hypertension, complicated with asymptomatic intracardiac thrombus and managed appropriately with medical treatment.

In the healthy brain, less than 5% of α-synuclein (α-syn) is phosphorylated at serine 129 (Ser(P)-129). However, within Parkinson disease (PD) Lewy bodies, 89% of α-syn is Ser(P)-129. The effects of Ser(P)-129 modification on α-syn distribution and solubility are poorly understood. As α-syn normally exists in both membrane-bound and cytosolic compartments, we examined the binding and dissociati...

The choroid plexus maintains the homeostasis of critical molecules in the brain by regulating their transport between the blood and cerebrospinal fluid (CSF). The current study was designed to investigate the potential role of the blood-CSF barrier (BCSFB) in α-synuclein (a-Syn) transport in the brain as affected by exposure to manganese (Mn), the toxic metal implicated in Parkinsonian disorder...

Accumulation of α-synuclein (α-syn) fibrils in Lewy bodies and Lewy neurites is the pathological hallmark of Parkinson disease (PD). Ligands that bind α-syn fibrils could be utilized as imaging agents to improve the diagnosis of PD and to monitor disease progression. However, ligands for α-syn fibrils in PD brain tissue have not been previously identified and the feasibility of quantifying α-sy...

Alpha-synuclein (a-Syn), a protein implicated in Parkinson disease, contributes significantly to dopamine metabolism. a-Syn binding inhibits the activity of tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine synthesis. Phosphorylation of TH stimulates its activity, an effect that is reversed by protein phosphatase 2A (PP2A). In cells, a-Syn overexpression activates PP2A. Here ...

Early α-synuclein (α-Syn)-induced alterations are neurite pathologies resulting in Lewy neurites. α-Syn oligomers are a toxic species in synucleinopathies and are suspected to cause neuritic pathology. To investigate how α-Syn oligomers may be linked to aberrant neurite pathology, we modeled different stages of α-Syn aggregation in vitro and investigated the interplay of α-Syn aggregates with p...
