The present study investigated the effect of early life stress in adolescent rats on brain metabolites, serum corticosterone, and depressive-like behavior. A group of rats was subject to early life stress from postnatal day (PND) 1 to 14. A matched control group was studied. Behavioral tests, serum corticosterone and high-resolution proton magnetic resonance spectroscopy were conducted between PND 30 and 40. In this study, adolescent rats exposed to early life stress demonstrated depressive-like behavior and increased serum corticosterone during adolescence. They also showed reduced glutamate, glutamine, and N-acetylaspartate (NAA) levels in the prefrontal cortex. A reduced myo-inositol level, consistent with astroglial deficits, was observed but was not statistically significant. Together, these findings characterize the effect of early life stress on adolescent animals and underscore the long-lasting and detrimental effects of childhood adversities.

Life was originated from inorganic world and had experienced a long period of evolution in about 3.8 billion years. The time for emergence of the pioneer creations on Earth is debatable nowadays, and how the scenario for the prebiotic molecular interactions is still mysterious.

Cannabis use during pregnancy is increasing; the study of adverse outcomes in cannabis-exposed pregnancies is therefore important. Previous articles in this series described increased risks of maternal adverse outcomes, fetal adverse outcomes, birth defects in newborns, and autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) in childhood. This article examines neuropsychiatric adverse outcomes in offspring gestationally exposed to cannabis.

Background And Purpose: Treatment of idiopathic scoliosis in childhood aims to prevent curve progression. It is generally accepted that curves > 50° have the highest risk of progression, but less well described is what happens with mild to moderate curves. The aim of this study was to assess long-term curve progression and health-related quality of life (HRQoL) and compare thoracic and thoracolumbar/lumbar (TL/L) curves.

Objectives: This study aimed to determine the metabolic syndrome (MS) prevalence in a sample of adolescents, to calculate their continuous metabolic syndrome scores, and to determine the associations of continuous metabolic syndrome score with overweight/obesity and selected cardiometabolic and lifestyle factors.
Methods: We enrolled a sample of 2,590 adolescents (1,180 males, mean age 17.1 ± 1.
Since microRNAs (miRNAs) serve as markers for early cancer diagnosis, it is crucial to develop a novel biosensor to detect miRNAs quickly, sensitively and selectively. Hence, we developed a fluorescence biosensor based on target miRNA-initiated rolling circle amplification (RCA) to generate RCA products with multiple tandem catalytic hairpin DNA templates that trigger primer exchange reactions (PER) which extend short single-strand DNA (ssDNA) primers into long ssDNA. Subsequently, the long ssDNA activates the -cleavage activity of the clustered regularly interspaced short palindromic repeats (CRISPR)/Cas12a system to cleave a fluorescent reporter chain, enabling ultrasensitive detection of miRNAs through the output fluorescence signal.
