In this proposal, we will (1) detect the associations between BDNF and Trk B gene DNA methylation, histone modification, psychotic symptoms, obesity, suicide and antipsychotic drug responses in Taiwanese patients (2) discuss the possible mechanisms of epigenetic regulation of BDNF and Trk B in schizophrenia patients.
A total 160 subjects (80 subjects every year, including 40 healthy controls and 40 schizophrenia patients) will be recruited during a 2-year period. The first year, the baseline data of BDNF and Trk B DNA methylation, protein and mRNA levels in all subjects will be collected and the following 1 months data will also be collected in schizophrenia with antipsychotic drug treatments. The second year, the baseline data of BDNF and Trk B histone modification in all subjects will be collected.

The aim of this study is to show for the first time that treatment with intravenous fibrinolysis using rt-PA in patients with recent ischemic stroke is accompanied by increases in circulat...
This study will examine the effectiveness of combining cognitive therapy with enriched usual care for preventing subsequent suicide attempts in people with a drug dependence who have recen...
France is one of the European countries with the highest rate of death by suicide, more than 10 400 deaths each year, about 16 people out of 100 000. Although suicide mortality rate tends ...
Bipolar disorder (BD) is also named as a bipolar affective disorder, belonging to a kind of severe mental disorder involving both mania or hypomania and depression episode, with lifetime p...
BDNF has been linked to the pathogenesis of airway hyperresponsiveness in asthma. In this trial, the impact of a treatment with salmeterol and salmeterol / fluticasone on BDNF concentratio...
The structure of brain-derived neurotrophic factor (BDNF) gene is complex, which is composed of eight non-coding exons and one coding exon, each of them has its own unique promoter. Multiple BDNF tran...
Suicide is a significant public health problem worldwide. Suicide rates among elderly persons (≥ 65 years of age) are three times higher than those of younger people in Korea. The emergency departme...
A paucity of corroborative psychological and psychiatric evidence may be inhibiting detection of drug intoxication suicides in the United States. We evaluated the relative importance of suicide notes ...
This study examined whether different components of capability for suicide (i.e., fearlessness about death, pain tolerance, pain insensitivity, preparation for suicide, suicide plan, and courage), as ...
Depression and posttraumatic stress disorder are assumed to be maladaptive responses to stress and antidepressants are thought to counteract such responses by increasing BDNF (brain-derived neurotroph...
Addition of methyl groups. In histo-chemistry methylation is used to esterify carboxyl groups and remove sulfate groups by treating tissue sections with hot methanol in the presence of hydrochloric acid. (From Stedman, 25th ed)
A branch of genetics which deals with the genetic variability in individual responses to drugs and drug metabolism (BIOTRANSFORMATION).
Forms to which substances are incorporated to improve the delivery and the effectiveness of drugs. Drug carriers are used in drug-delivery systems such as the controlled-release technology to prolong in vivo drug actions, decrease drug metabolism, and reduce drug toxicity. Carriers are also used in designs to increase the effectiveness of drug delivery to the target sites of pharmacological actions. Liposomes, albumin microspheres, soluble synthetic polymers, DNA complexes, protein-drug conjugates, and carrier erythrocytes among others have been employed as biodegradable drug carriers.
The act of killing oneself.
An enzyme responsible for producing a species-characteristic methylation pattern on adenine residues in a specific short base sequence in the host cell DNA. The enzyme catalyzes the methylation of DNA adenine in the presence of S-adenosyl-L-methionine to form DNA containing 6-methylaminopurine and S-adenosyl-L-homocysteine. EC 188.8.131.52.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
