Regional cerebral metabolism alterations and functional connectivity in individuals with opioid use disorder: An integrated resting-state PET/fMRI study.

Individuals with opioid use disorder (OUD) have been reported to show abnormal brain metabolism and impaired coupling among brain networks such as the default mode network (DMN), salience network (SN), and executive control network (ECN). However, the characteristics of brain glucose metabolism and its related functions in the brain networks in individuals with OUD remain unknown. Thirty-six individuals with OUD and thirty matched healthy controls (HCs) were recruited in this integrated positron emission tomography/magnetic resonance imaging (PET/MRI) study.

Repetitive transcranial magnetic stimulation modulates coupling among large-scale brain networks in heroin-dependent individuals: A randomized resting-state functional magnetic resonance imaging study.

The abnormal interactions of three key large-scale brain networks (default mode [DMN], salience and executive control [ECN]) were showed underlie dysfunctions in heroin addiction. Repetitive transcranial magnetic stimulation (rTMS) targeting the left dorsolateral prefrontal cortex (DLPFC) is a potential treatment for heroin addiction. It is unclear whether impaired coupling among the large-scale brain networks would be improved by rTMS in treated heroin-dependent individuals.

Long-term results after deep brain stimulation of nucleus accumbens and the anterior limb of the internal capsule for preventing heroin relapse: An open-label pilot study.

Background: Deep brain stimulation (DBS) is currently used to treat addiction, with the nucleus accumbens (NAc) as one promising target. The anterior limb of the internal capsule (ALIC) is also a potential target, as it carries fiber tracts connecting the mesocorticolimbic circuits that are crucially involved in several psychiatric disorders, including addiction. Stimulating the NAc and ALIC simultaneously may have a synergistic effect against addiction.

Therapeutic effects of adenovirus-mediated CD and NIS expression combined with NaI/5-FC on human thyroid cancer.

Thyroid cancer is the most common type of malignant endocrine tumor diagnosed. Previous studies have indicated that gene therapy is the most promising and effective therapeutic method for thyroid cancer. Therefore, in the present study, NaI/5-fluorocytosine (5-FC) treatment was combined with cytosine deaminase (CD, encoded by the gene) and sodium iodide symporter (NIS, encoded by the gene) to act together as a therapeutic tool for thyroid cancer.

Four FCRL3 Gene Polymorphisms (FCRL3_3, _5, _6, _8) Confer Susceptibility to Multiple Sclerosis: Results from a Case-Control Study.

Multiple sclerosis (MS) is an autoimmune/inflammatory neurodegenerative disease which mainly affects the central nervous system in young adults. Fc-receptor-like-3 (FCRL3) gene, which involved in immune cell regulation, has drawn lots of attentions. This study aims to investigate the association between common polymorphisms of FCRL3 gene and MS risk in a Chinese Han population.

MicroRNA-101 inhibits rat cardiac hypertrophy by targeting Rab1a.

Cardiac hypertrophy is a primary pathological change associated with cardiovascular diseases. Dysregulated microRNAs are frequent in cardiovascular diseases and contribute to cardiac hypertrophy by regulating a series of targeted genes. In this study, a rat model of cardiac hypertrophy was created by transverse abdominal aortic constriction, and cardiomyocyte hypertrophy in cultured neonatal rat cardiomyocytes was induced using angiotensin II (AngII) to investigate the role of miR-101 in myocardial hypertrophy.
