Background: Previous studies reported default mode network (DMN) and limbic (LIN) brain perfusion deficits in patients with amnestic mild cognitive impairment (aMCI), frequently a prodromal stage of Alzheimer’s disease (AD). However, the validity these measures as AD markers has not yet been tested using MRI arterial spin labeling (ASL). Objective: To investigate convergent discriminant DMN LIN...

Abdominal cerebrospinal fluid (CSF) pseudocyst is an uncommon complication following ventriculo-peritoneal (VP) shunt. The following report’s our experience with three cases of CSF pseudocyst in children. VP shunt was done earlier for communicating hydrocephalus following tubercular meningitis (TBM) in all cases. Clinical presentation was with progressive abdominal distension and features of in...

TO THE EDITOR—The recent article by Guven et al [1], titled “Neurobrucellosis: Clinical and Diagnostic Features,” sheds light on many important yet vexing issues in the clinical presentation, diagnosis, andmanagementofarelativelycommon zoonotic infection. The relevance of discussing this issue is understated by the lack of consensus in the diagnosis and management of neurobrucellosis, in combin...

In order to study the pathogenesis of plasma cell dyscrasias with associated clinical features of chronic neutrophilic leukaemia, the concentration of granulocyte-colony stimulating factor (G-CSF) was measured in a patient, a 73 year old man, who underwent steroid pulse therapy. High G-CSF concentrations and leucocyte counts prior to treatment declined rapidly on administration of dexamethazone...

We report on the analysis of endogenous peptides in cerebrospinal fluid (CSF) by mass spectrometry. A method was developed for preparation of peptide extracts from CSF. Analysis of the extracts by offline LC-MALDI MS resulted in the detection of 3,000-4,000 peptide-like features. Out of these, 730 peptides were identified by MS/MS. The majority of these peptides have not been previously reporte...

To validate its efficacy in the context of the human immune system, a novel therapeutic vaccine of hGM-CSF/hTNFα surface-modified PC-3 cells against human prostate cancer was evaluated in the human peripheral blood lymphocytes-severe combined immunodeficiency (huPBL-SCID) chimeric mouse model. The hGM-CSF or/and hTNFα modified vaccines inhibited prostate cancer growth effectively so as to prolo...

Background It is still not clear about the independent contribution of ATN biomarkers (amyloid beta [A], pathologic tau [T], and neurodegeneration [N]) on top neuropsychological tests for risk estimation amnestic mild cognitive impairment (aMCI) in subjects with normal cognition (NC). Method We included 306 NC who underwent were available cerebrospinal fluid (CSF) examinations, MRI FDG-PET at b...

Bats carry and shed many emerging infectious disease agents including Ebola virus and SARS-like Coronaviruses, yet they rarely display clinical symptoms of infection. Bat epithelial or fibroblast cell lines were previously established to study the bat immune response against viral infection. However, the lack of professional immune cells such as dendritic cells (DC) and macrophages has greatly ...

Orexins are neuropeptides selectively expressed in a small number of neurons in the lateral-posterior hypothalamus. We measured orexin-A in the cerebrospinal fluid (CSF) of 66 patients with major depressive disorder (MDD), dysthymia and adjustment disorder after a suicide attempt. Blood samples confirmed that the patients were free from antidepressive and neuroleptic medication at the time of t...

Cryptococcus neoformans is the most common microorganism found in cerebrospinal fluid (CSF) cytology and causes life-threatening infections in immunocompromised hosts. Although its cytomorphologic features in conventional smear cytology have been well described, those in liquid-based cytology have rarely been. A 73-year-old woman with diffuse large B-cell lymphoma presented with mental confusio...
