Effects of Low-Intensity Transcranial Magnetic Stimulation in Neuropsychological Development of Pediatric Subjects With Autism Spectrum Disorder: A Longitudinal Retrospective Approach.

Background: Autism spectrum disorder (ASD) is a heterogeneous neurobiological condition characterized by behavioral problems and delayed neurodevelopment. Although transcranial magnetic stimulation (TMS) has been proposed as an alternative treatment for patients with ASD because of its promising benefits in reducing repetitive behaviors and enhancing executive functions, the use of high-intensity pulses (Hi-TMS) appears to be related to the side effects of the therapy. Low-intensity TMS (Li-TMS) has been partially investigated, but it may have clinical effects on ASD and simultaneously increase treatment safety.

Global metabolomic alterations associated with endocrine-disrupting chemicals among pregnant individuals and newborns.

The Relative Reinforcing Value of Menthol Among Young Adult Cigarette Smokers: Results From a Behavioral Choice Task.

Introduction: Menthol cigarettes are associated with experimentation and progression to regular use. Although reinforcement processes likely underlie menthol's appeal, the reinforcing value of menthol cigarettes remains unknown.

Aims And Methods: This study examined the relative reinforcing value (RRV) of menthol versus nonmenthol cigarettes in young adult menthol (n = 54) and nonmenthol (n = 53) smokers, and differences in menthol's RRV by race, ethnicity, and sexual orientation.

Predictors of early child development for screening pregnant women most in need of support in Brazil.

Background: Home visiting programmes can support child development and reduce inequalities, but failure to identify the most vulnerable families can undermine such efforts. We examined whether there are strong predictors of poor child development that could be used to screen pregnant women in primary health care settings to target early interventions in a Brazilian population. Considering selected predictors, we assessed coverage and focus of a large-scale home visiting programme named Primeira Infância Melhor (PIM).

CRISPR-Cas9-mediated barcode insertion into for surrogate tracking.

Unlabelled: The use of surrogate organisms can enable researchers to safely conduct research on pathogens and in a broader set of conditions. Being able to differentiate between the surrogates used in the experiments and background contamination as well as between different experiments will further improve research efforts. One effective approach is to introduce unique genetic barcodes into the surrogate genome and track their presence using the quantitative polymerase chain reaction (qPCR).
