Macrocephaly and bitemporal arachnoid cysts not associated with glutaric aciduria type I in a child.
A 45-month-old child who had bitemporal arachnoid cysts and macrocephaly unrelated to glutaric aciduria type 1 (GA 1) was reported. The patient was admitted to the emergency unit after head trauma at 11 months of age. CT and MRI showed bitemporal arachnoid cysts (BACs). Acylcarnitine profile was normal in serum using tandem mass spectrometry. Urine and blood screening tests were within normal r...
objective: finding a suitable laboratory test that can diagnose schizophrenia in its early stages could be very important. according to the hypothesis of lack of noradrenalin balance in the brain, it is illustrated that the disorder severity has a negative correlation with the amount of urine noradrenalin metabolite [3-methoxy-4-hydroxy phenyl glycol (mhpg) sulfate]. in this research, instead o...
Estimation of wastewater composition (Chemical Organic Demand – COD and nitrogen-related species such as ammonia and organic nitrogen) for on-line control of treatment plants based on Principal Components Regression (PCR) and Partial Least Squares (PLS) applied to spectrometric data (turbidity, UV-visible and synchronous fluorescence spectra). Satisfactory models were obtained based on the tota...
Pancytopenia in childhood can be caused by a variety of underlying diseases including hematological and non-hematological entities. Phenylketonuria (PKU) is an inborn error of phenylalanine metabolism. No association between PKU and pancytopenia has ever been reported. We report the first case of PKU revealed by a pancytopenia at presentation. The patient was an infant girl born to healthy non-...
The analysis of polar metabolites based on liquid chromatography-mass spectrometry (LC-MS) methods should take into consideration the complexity interactions in LC columns to be able cover a broad range key biological pathways. Therefore, this study, different chromatographic were tested for including reversed-phase and hydrophilic interaction chromatography (HILIC) columns. Based column screen...
In previous work on antennal gland function in Crustacea the study of reabsorption of organic materials from the urine has been confined entirely to a consideration of carbohydrates, particularly glucose. For reviews of this earlier work, see Martin (1957) and Parry (i960). In Carcinus, as in other decapods, glucose is removed by active transport from urine passing through the antennal gland, t...
INTRODUCTION Severe falciparum malaria is commonly complicated by metabolic acidosis. Together with lactic acid (LA), other previously unmeasured acids have been implicated in the pathogenesis of falciparum malaria. METHODS In this prospective study, we characterised organic acids in adults with severe falciparum malaria in India and Bangladesh. Liquid chromatography-mass spectrometry was use...
Metabolic carboxylic acids are extracted, with a mixture of equal volumes of t-amyl alcohol-chloroform, from an acidifiedsample of as littleas 200 tI of urine that has been adsorbed to a short column of silicagel. Total acid in the extract is measured by titrationwith tetramethylammonium hydroxide (10 mmol/liter) to a phenolphthalein end point.There is no interferencefrom protein,creatinine, cr...
Lithium (Li) treatment for bipolar affective disorders is associated with a variety of renal side effects. The metabolic response of the kidney to chronic Li treatment has rarely been studied. We applied a novel method of (1)H-nuclear magnetic resonance (NMR)-based metabonomics to integrate metabolic profiling and to identify the changes in the levels of metabolites in the kidney and urine from...
BACKGROUND Nowadays, the Nuclear Magnetic Resonance (NMR) techniques are tested for metabolomic urine profile in order to detect early damage of kidney. OBJECTIVES The purpose of this investigation was the initial assessment of two-dimensional J-resolved NMR urine spectra analysis usability for early kidney injuries detection. The amino acids (AA) and acids profile change after the exposure t...
