The majority of cases of spontaneous intracranial hypotension (SIH) result from spontaneous cerebrospinal fluid (CSF) leaks. The disorder has a broad clinical and imaging spectrum, with substantial variability in clinical and imaging features, in CSF findings, and in response to treatment. Headache is the most common symptom, and is typically orthostatic, but with chronicity the orthostatic fea...

Analytical and biological variability are issues of central importance to human metabolomics studies. Here both types of variation are examined in human plasma and cerebrospinal fluid (CSF) using a global liquid chromatography/mass spectrometry (LC/MS) metabolomics strategy. The platform shows small analytical variation with a median coefficient of variation (CV) of 15-16% for both plasma and C...

Blast colony assays were performed on freshly obtained bone marrow samples from 19 newly diagnosed or relapsed children with acute lymphoblastic leukemia (ALL) of B lineage to determine the effect of added granulocyte-monocyte colony-stimulating factor (GM-CSF). Of the 19 marrow samples tested, 7 responded to GM-CSF with a mean increase in ALL blast colonies of 346%. Blast cells from one of the...

In this paper,we propose a new approach for writer identification of Chinese handwritten.In our method, we deal with writer identification of Chinese handwritten using Chinese character structure features(CSF) and extreme learning machine(ELM).To extract the features embedded in Chinese handwriting characters, special structures have been explored according to the trait of Chinese handwriting c...

Macrophages or mononuclear phagocytes are heterogeneous populations present throughout the body which can adapt quite dramatically to the surrounding milieu, both in the steady state and during immune/inflammatory responses. To assist in our understanding of this diversity, they have been classified into polarization or “activation” states, termed M1 and M2, respectively. This in vitro classifi...

BACKGROUND/AIMS Granulocyte macrophage colony-stimulating factor (GM-CSF) is a hematopoietic growth factor, 23 kDA molecular weight with a glycoprotein nature, which is also an immune modulator. The levels of GM-CSF and its role in the pathophysiology of several cancers such as ovarian, breast have been investigated. The aim of the present study was to determine the effect of GM-CSF and carcino...

BACKGROUND Granulocyte macrophage colony-stimulating factor (GM-CSF) is currently widely used as an adjuvant in cancer immunotherapy. However, recent studies have shown that GM-CSF can impair anti-tumor immune responses. Thus the role of GM-CSF in clear-cell renal cell carcinoma (ccRCC) remains unraveled. Our present study aims to investigate the prognostic significance of intratumoral GM-CSF i...

BACKGROUND Knowledge of the entire protein content, the proteome, of normal human cerebrospinal fluid (CSF) would enable insights into neurologic and psychiatric disorders. Until now technologic hurdles and access to true normal samples hindered attaining this goal. METHODS AND PRINCIPAL FINDINGS We applied immunoaffinity separation and high sensitivity and resolution liquid chromatography-ma...

Hippocampal atrophy as assessed by magnetic resonance imaging (MRI) and abnormal cerebrospinal fluid (CSF) biomarkers are supportive features for the diagnosis of Alzheimer's disease (AD) and are assumed to be indirect pathological markers of the disease. In AD patients, antemortem MRI hippocampal volumes (HVs) correlate with the density of neurofibrillary tangles (but not with senile plaques) ...

Diagnostic confusion often exists between tuberculous meningitis and other meningoencephalitides. Newer diagnostic tests are unlikely to be available in many countries for some time. This study examines which clinical features and simple laboratory tests can differentiate tuberculous meningitis from other infections. Two hundred and thirty two children (110 tuberculous meningitis, 94 non-tuberc...
