Very-long-chain acyl-CoA dehydrogenase (VLCAD) is one of four straight-chain (ACD) enzymes, which are all nuclear encoded mitochondrial flavoproteins catalyzing the initial step in fatty acid beta-oxidation. We have used very fast, Rapid Amplification cDNA Ends (RACE) based strategy to obtain sequence cDNAs encoding human VLCAD from placenta and fibroblasts. Alignment predicted amino with those other ACD enzymes revealed extensive homology. Moreover, oxidase showed homology corroborating...

The accumulation of β-oxidation intermediates was studied by incubating normal and enzyme-deficient human fibroblasts with [2H4]linoleate L-carnitine analyzing the resultant acylcarnitines tandem mass spectrometry. Labeled decenoyl-, octanoyl-, hexanoyl-, butyrylcarnitines were only observed cells. Intermediates longer chain length, corresponding to substrates for enzymes associated inner mitochondrial membrane, not unless a cell line deficient in one these enzymes, such as very-long-chain...

The mitochondrial metabolism of 5-enoyl-CoAs, which are formed during the beta-oxidation unsaturated fatty acids with double bonds extending from odd-numbered carbon atoms, was studied extracts and purified enzymes beta-oxidation. Metabolites were identified spectrophotometrically by high performance liquid chromatography. 5-cis-Octenoyl-CoA, a putative metabolite linolenic acid, efficiently dehydrogenated medium-chain acyl-CoA dehydrogenase (EC 1.3.99.3) to 2-trans-5-cis-octadienoyl-CoA,...

Several inherited disorders of fatty acid beta-oxidation have been described that relate mainly to saturated precursors. This study is the first report an enzyme defect related only unsaturated oxidation and provides in vivo evidence fat humans proceeds by reductase-dependent pathway. The patient was a black female, presenting neonatal period with persistent hypotonia. Biochemical studies revealed hyperlysinemia, hypocarnitinemia, normal organic profile, unusual acylcarnitine species both...

BACKGROUND: Children with cerebral palsy (CP) can present severe secondary dystonia or without associated spasticity of their extremities. OBJECTIVE: To assess the outcomes combined anterior and posterior lumbar rhizotomy for treatment mixed hypertonia in lower extremities children CP. METHODS: Fifty CP were subjected to rhizotomies a prospective study. Clinical outcome measurements recorded preoperatively evaluated at 2, 6, 12 months postoperatively. The operative techniques performed by...

Amniocytes isolated from two pregnancies at risk for fatty acid oxidation defects were incubated with stable isotopically labelled palmitate, in the presence of L-carnitine, to probe that pathway. The acylcarnitines then quantitated using tandem mass spectrometry. a pregnancy medium-chain acyl-CoA dehydrogenase (MCAD) deficiency produced characteristic acylcarnitine profile increased levels octanoylcarnitine and decanoylcarnitine, indicative MCAD deficiency. DNA analysis confirmed fetus was...

Introduction: Hypocalcemia is an important and common complication following thyroid surgery with reports varying from 0.5% to 75%. Despite being self-limiting in most patients, symptomatic hypocalcemia of particular concern because a delay its manifestation the consequent need for prolonged patient hospitalization or re-admission. Aim Work: The aim this study evaluate clinical usefulness oral calcium vitamin D administration after total thyroidectomy prevention post-operative hypocalcemia....

Thoracic and lumbar fractures represent nearly 90% of traumatic spine injuries. Thoracolumbar region is susceptible to injury because its location between the stiff kyphotic thoracic mobile lordotic region. To compare short-segment fixation with screws into index level long-segment in maintaining angle correction pain. A prospective study included 91 patients, who had single-level thoracolumbar fracture Cobb's ≤ 25° underwent posterior fixation. Forty-four patients level, 47 skipped level....
