Detection of Atherosclerotic Plaques in the Rabbit Aorta Using Ultrasound Microbubbles Conjugated to Interleukin-18 Antibodies.

BACKGROUND The purpose of the study was to investigate the ability of microbubbles (MBs) targeting interleukin-18 (IL-18) to detect plaques in a rabbit atherosclerotic plaque model. MATERIAL AND METHODS A rabbit atherosclerotic plaque model was established. The locations of the atherosclerotic plaques were verified by two-dimensional scanning and color Doppler flow imaging.

Attenuation of hepatic fibrosis through ultrasound-microbubble-mediated HGF gene transfer in rats.

Objective: The objective was to explore the feasibility of ultrasound-microbubble-mediated hepatocyte growth factor (HGF) gene transfer for treating rat hepatic fibrosis induced by CCl(4).

Methods: Forty-eight male SD rats were divided into ultrasound-microbubble-HGF group (U-M-HGF group), ultrasound-HGF group (U-HGF group), microbubble-HGF group (M-HGF group), HGF group (HGF group), CCl(4) group (control group), and normal group. The serum levels of alanine transaminase (ALT), aspartate transaminase (AST), total protein, albumin (ALB), and globulin (GLB) and the ratio of ALB/GLB were determined after treatment.

Polymorphisms of androgen receptor gene in childhood and adolescent males with first-onset major depressive disorder and association with related symptomatology.

This study was designed to explore the association between CAG repeats in AR gene and major depressive disorder (MDD) in male children and adolescents. The results showed that there were differences between adolescent depressive patients and adolescent controls in CAG repeats' length and alleles' distributions, and the severity of depression and anxiety was negatively correlated with the length of CAG repeats in adolescent patients. This suggested that AR gene might be involved in the depressive upset in adolescents, and the age- and sex-related prevalent differences might also be associated to CAG repeats.

Comparison of the polymorphisms of androgen receptor gene and estrogen alpha and beta gene between adolescent females with first-onset major depressive disorder and controls.

This study was to elucidate the role of genetic variation in androgen receptor (AR) gene, estrogen receptor alpha (ER alpha) and ER beta gene on first-onset major depressive disorder (MDD) in female adolescents. Results showed that AR gene in MDD group have shorter microsatellites' length, and ER beta gene have shorter microsatellites' length and higher rates of S alleles, SS, genotype, and lower rate of LL genotype than control group. The results suggest that shorter length of AR and ER beta gene microsatellites might influence the onset of MDD in female adolescents, a further elucidation of the mechanisms is warranted.
