OBJECTIVE Validating self-reported questionnaires to detect depression during pregnancy, compared to depression during postpartum, has gained much less attention. Furthermore, it is unknown whether it is appropriate to use the same cutoff point to detect depression on different trimesters of pregnancy. The aims of this study, conducted in pregnant Taiwanese(More)
BACKGROUND Perinatal depression is common, and treatment remains challenging. Depression has been reported to be associated with the abnormality of omega-3 polyunsaturated fatty acids (PUFAs). A profound decrease of omega-3 PUFAs in the mother during pregnancy is associated with the higher demand of fetal development and might precipitate the occurrence of(More)
BACKGROUND Agonists at the N-methyl-D-aspartate (NMDA)-glycine site (D-serine, glycine, D-alanine and D-cycloserine) and glycine transporter-1 (GlyT-1) inhibitor (N-methylglycine, or called sarcosine) both improve the symptoms of stable chronic schizophrenia patients receiving concurrent antipsychotics. Previous studies, however, found no advantage of(More)
BACKGROUND Antidepressants, aiming at monoaminergic neurotransmission, exhibit delayed onset of action, limited efficacy, and poor compliance. Glutamatergic neurotransmission is involved in depression. However, it is unclear whether enhancement of the N-methyl-D-aspartate (NMDA) subtype glutamate receptor can be a treatment for depression. METHODS We(More)
BACKGROUND Small molecules that enhance the N-methyl-D-aspartate (NMDA) neurotransmission have been shown to be beneficial as adjuvant therapy for schizophrenia. Among these compounds, sarcosine (a glycine transporter-I inhibitor), when added to an existing regimen of antipsychotic drugs, has shown its efficacy for both chronically stable and acutely ill(More)
OBJECTIVE The Val158Met polymorphism of the catechol-O-methyltransferase gene has been demonstrated to be associated with prefrontal executive function explaining 4% of variance in perseverative errors on the Wisconsin Card Sorting Test (WCST). Studies suggest that dopamine D(1) and D(3) and serotonin 5-HT(2A) and 5-HT(6) receptors may also be involved in(More)
OBJECTIVE A serious side effect of atypical antipsychotics is increased body weight, which leads to further morbidity and nonadherence to medication. It has been suggested that both genetic and nongenetic variables may influence antipsychotics-related weight gain. This study aimed to simultaneously explore the effects of multiple candidate genes and(More)
AIM To test whether the genetic polymorphisms within the gene encoding the UGT2B7 gene may have an impact on methadone treatment. MATERIALS & METHODS Twelve SNPs in UGT2B7 were selected. 366 methadone maintenance treatment patients in Taiwan were recruited and genotyped. RESULTS In a genotype recessive model, rs6600879, rs6600880, rs4554144, rs11940316,(More)
Abstract Methadone maintenance therapy is an established treatment for heroin dependence. This study tested the influence of functional genetic polymorphisms in CYP2C19 gene encoding a CYP450 enzyme that contributes to methadone metabolism on treatment dose, plasma concentration, and side effects of methadone. Two single nucleotide polymorphisms (SNPs),(More)
BACKGROUND Phospholipase A2 (PLA2) and cyclooxygenase 2 (COX2) are the two key enzymes in the metabolism of polyunsaturated fatty acids, which in turn play an important role in cytokine-induced depression and sickness behavior. METHODS Patients with chronic hepatitis C viral infection (n = 132) were assessed to examine the effects of seven single(More)
