3-methylcrotonyl-CoA carboxylase deficiency is an autosomal recessive disorder characterized by a defect in leucine catabolism. We report the case of an 80-day-old patient with 3-methylcrotonyl-CoA carboxylase deficiency who had elevated levels of 3-hydroxyisovalerylcarnitine (45.56 micromol/L; reference range, <0.65 micromol/L), which was detected using tandem mass spectrometry during newborn screening, and elevated levels of 3-hydroxyisovaleric acid (375.75 mmol/mol Cr) and 3-methylcrotonylglycine (502.36 mmol/mol Cr ), which were detected in urine organic acid analysis. We performed direct sequence analysis of all the exons of the MCCC1 and MCCC2 genes. No mutations were detected in the direct sequence analysis of MCCC1. However sequencing of the MCCC2 gene revealed a mutation caused by a heterozygous G to C transversion [c.313G>C (p.Gly105Arg)] at nucleotide position 313 and a mutation caused by a heterozygous A to T transversion [c.1252A>T (p.lle418Phe)] at nucleotide position 1252. Identification of these 2 novel MCCC2 gene mutations in our patient suggested that analysis of the MCCC1 and MCCC2 genes might prove useful in the diagnosis of 3-methylcrotonyl-CoA carboxylase deficiency.

OBJECTIVES: Ovarian hormones have been shown to regulate body weight, intra-abdominal fat accumulation and plasma level of cytokines. The aim of this study was to investigate the effect of estrogen replacement therapy on visceral adipose tissue, plasma level of apelin, lipid profiles, and glucose in ovariectomized (OVX) rats. METHODS: Thirty female Wistar rats were divided into OVX (n = 20) and sham (n = 10) groups. OVX rats were subdivided into estrogen replacement therapy (OVX+est; n = 10) receiving 17 β-estradiol valerates (30 µg/kg, s.c., 5 day/week, for eight weeks), and vehicle control group receiving sesame oil same as experiment group (OVX+ses oil; n = 10). After the treatments, all groups were sacrificed and blood samples were collected, visceral fats were taken from the abdominal cavity and weighed immediately. Apelin were measured using enzyme-linked immunosorbent assay kits. Lipid profiles and glucose were measured using the enzymatic colorimetric method. Data were analyzed with one-way analysis of variance and (P < 0.05) determined as the statistical significance level. RESULTS: After eight weeks, body weight, body mass index (BMI), visceral fat, apelin and lipid profiles (P < 0.01) were increased significantly in OVX rats compared to sham group. Treatment with estrogen leads to significant reduction in body weight and BMI (P < 0.05), there was no significant change in serum apelin level in OVX+est rats compared to OVX+ses. CONCLUSIONS: These results suggest that estradiol replacement therapy successfully attenuated some of the metabolic syndrome components, and apelin does not probably stand as a mediator of these physiological functions.

Valproic acid intoxication is a fairly common clinical problem that can result in serious complications. Traditionally the treatment of valproic acid overdose has been limited to supportive measures, but high blood levels may require extracorporeal removal, and publications on this experience are scarce. This case demonstrated continuous veno-venous hemodiafiltration successfully used in patient with severe valproic acid overdose who was hemodynamically unstable.

Polyhydroxyalkanoates (PHA) is a family of microbially synthesized polyesters consisting of various 3-hydroxyalkanoate monomers. Aeromonas hydrophila 4AK4 could be able to synthesize PHA copolymer consisting of 3-hydroxybutyrate (3-HB) and 3-hydroxyhexanoate (3-HHx). No data has been reported about the ability to synthesize the PHA with other monomers in A. hydrophila. In this study, propionic acid, valeric acid, heptanoic acid, nonanoic acid and undecanoic acid were used together with gluconate to find out whether A. hydrophila 4AK4 could synthesize the PHA consisting of odd carbon atom number monomers. The result showed that A. hydrophila 4AK4 could not growth when supplied with propionic acid, valeric acid, heptanoic acid and nonanoic acid and only undecanoic acid could be used to synthesize PHA. Wild type and recombinant A. hydrophila 4AK4 harboring phaA (beta-ketothiolase) and phaB (acetoacetyl-CoA reductase) were cultivated with undecanoic acid and glucose or undecanoic acid and gluconate served as carbon sources. PHA consisting of 3-HB and 3-hydroxyvalerate (3-HV) could be produced by both wild type and recombinant A. hydrophila 4AK4 and the latter could produce PHA with more 3-HB monomer. When the ratio of glucose or gluconate to undecanoic acid was 1:1, the cell dry weight (CDW) of A. hydrophila 4AK4 reached 1.14 g/L and PHA content was 60% of the CDW after cultivation for 24 h. When lauric acid and undecanoic acid were served as co-substrate, A. hydrophila 4AK4 could produce copolyester consisting of 3-HB, 3-HV and 3-HHx. Along with the increase of undecanoic acid proportion in the mixed carbon source, the 3-HV content of copolymer was increased while the 3-HB and 3-HHx content were decreased. In all cases, the CDW decreased along with the increase of undecanoic acid concentration, which indicated that undecanoic acid was not very good for A. hydrophila 4AK4 growth.

BACKGROUND: CEDIA is a newly developed method for therapeutic drug monitoring (TDM) and has some merits such as easy application to routine chemical analyzers, rapid and precise quantitation even in low concentrations and less cross reactivity. We evaluated the CEDIA(epsilon) (Microgenics Co., CA, USA) in measurement of theophyllin, valproic acid and phenytoin levels using 502X(epsilon) (A & T, Tokyo, Japan) and compared the results to those of the TDx(epsilon) (Abbott Laboratories, IL, USA) in order to assess the utility of the CEDIA(epsilon). METHODS: We evaluated the performance of 502X(epsilon) in the aspects of the within-runs and the between-runs precision, linearity, and carry-over. We compared the results of the CEDIA(epsilon) reagent with those of TDx(epsilon). The control materials (Bio-Rad TDM control level 1 and level 3; Bio-Rad laboratories, CA, USA) and clinical specimens were used for these studies. RESULTS: The coefficients of variation (CV) for the within-run and the between-run imprecision of 502X(epsilon) were 2.0-7.6% and 4.0-6.5%, respectively. The carry-over rate for theophyllin, valproic acid and phenytoin was 1.33%, 0.45% and 0.53%, respectively. The linearity (r(2)) of theophyllin, valproic acid and phenytoin was 0.9941, 0.9983 and 0.9947, respectively. The correlation coefficients (r) of theophyllin, valproic acid and phenytoin levels of CEDIA(epsilon), with those determined by the TDx(epsilon), were 0.9730, 0.9703 and 0.9695, respectively (P<0.001). CONCLUSIONS: The recentlydeveloped CEDIA(epsilon) proved to be highly precise and linear for quantitative analysis of theophyllin, phenytoin and valproic acid. Correlations with TDx(epsilon) were significantly high. CEDIA(epsilon) was thought to be clinically useful for TDM.
