Department of Rehabilitation, The First Affiliated Hospital of Chongqing Medical University, Chongqing 400016, China; Chongqing Key Laboratory of Neurology, The First Affiliated Hospital of Chongqing Medical University, Chongqing 400016,  China. Electronic address:

Background: Transcranial direct current stimulation (tDCS) has an impact on improving cognitive and motor dysfunction induced by ischemia-reperfusion injury. However, to use this technology more rationally in clinical practice, a deepened understanding of the molecular mechanisms behind its therapeutic effects is needed. This study explored the role of the brain-derived neurotrophic factor(BDNF) and its associated receptor tropomyosin-receptor kinase B(TrkB) while deciphering the underlying mechanisms in transcranial direct current therapy to treat ischemic stroke.

Article Synopsis
  • Machine learning, particularly deep learning with convolutional neural networks (CNNs), is being used to detect prostate cancer in tissue slides, but sample type differences affect model accuracy.
  • Research tested whether CNNs trained on one type of sample (biopsy or radical prostatectomy) could effectively analyze the other type, revealing a significant drop in performance across sample types.
  • Results indicated that models performed well on their own sample but poorly on the alternative type, highlighting the need to consider morphological differences in training to improve cancer detection accuracy in clinical settings.*

Background: Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective therapy that improves lung disease in people with cystic fibrosis (pwCF), but its effect on glucose tolerance and insulin secretion is unclear.

Methods: PROMISE is a multicenter prospective, observational study of ETI in pwCF ≥12 years and at least one F508del allele. The PROMISE Endocrine sub-study (PROMISE-ENDO) enrolled participants at 10 CF Centers where hemoglobin A1c (HbA1c) was collected and 3-hour oral glucose tolerance tests (OGTT) conducted to examine glucose tolerance, glucose excursions, insulin secretory rates (deconvolution of C-peptide) and sensitivity (oral minimal model) prior to ETI and 12-18 months (mos) and 24-30 mos following ETI initiation.

In randomized, placebo controlled clinical trials (RCT) in major depressive disorders (MDD), treatment response (TR) is estimated by the change from baseline at study-end (EOS) of the scores of clinical scales used for assessing disease severity. Treatment effect (TE) is estimated by the baseline-adjusted difference at EOS of TR between active treatments and placebo.The TE is function of treatment-specific and, non-specific (NSRT) effect (referred as placebo effect), and placebo response.

Three water isolates were previously identified as promising antibiotic producers from freshwater sources in Wisconsin, United States. Each isolate produced effective antibiotics against three or more bacterial relatives of antibiotic resistant pathogens. The isolates were identified as , , and through 16S rRNA sequencing and further characterized with biochemical tests to verify the genus and species of each isolate.

Empathy Development in Preschoolers With/Without Hearing Loss and Its Associations with Social-Emotional Functioning.

Res Child Adolesc Psychopathol

December 2024

Unit of Developmental and Educational Psychology, Institute of Psychology, Faculty of Social and Behavioral Sciences, Leiden University, Leiden, The Netherlands.

Empathy plays a crucial role in children's social-emotional development. There is an increasing trend in recent studies to recognize empathy as a multi-dimensional construct, consisting of three distinct hierarchical levels: emotion contagion, attention to others' feelings and prosocial behaviors (Hoffman, Motiv Emot, 14(2), 151-172, 1990). The present study is amongst the first to use a longitudinal approach to examine the development trajectories of the distinct empathic levels, based on a sample of Chinese preschoolers aged 2 to 6 years, half of the sample being deaf or hard-of-hearing (DHH).

Pediatric opioid use-associated neurotoxicity with cerebellar edema (POUNCE) syndrome.

Clin Toxicol (Phila)

Division of Medical Toxicology, Ronald O. Perelman Department of Emergency Medicine, NYU Grossman School of Medicine, New York, NY, USA.

Introduction: Unfortunately, children are not spared from the devastating effects of the ongoing opioid epidemic. In rare cases, young children exposed to opioids present with unique neuroimaging findings affecting the white matter, reminiscent of what was once seen with diacetylmorphine (heroin)-associated leukoencephalopathy. This constellation of findings is termed the pediatric opioid use-associated neurotoxicity with cerebellar edema (POUNCE) syndrome.

  • Heart and lung transplantation are important treatments for severe heart and lung failure, but there's a shortage of donor organs, prompting interest in thoracoabdominal normothermic regional perfusion (TA-NRP) to enhance organ availability from circulatory death donors.
  • A study evaluated a single-center TA-NRP program, highlighting essential processes and challenges in its adoption, noting an average TA-NRP initiation time of about 7 minutes and overall duration of 87 minutes.
  • Key factors for successful implementation included identifying stakeholders, maintaining communication, addressing ethical concerns, and developing care protocols for all phases of the donation process.

Though it has no catalytic activity toward GM2 ganglioside, the GM2 activator protein (GM2A) is essential for ganglioside hydrolysis by facilitating the action of lysosomal ß-N-acetylhexosaminidase. GM2A deficiency results in death in early childhood due to rapid central nervous system deterioration similar to the related GM2 gangliosidoses, Tay-Sachs disease and Sandhoff disease. This manuscript further characterizes a feline model of GM2A deficiency with a focus on clinical and biochemical parameters that may be useful as benchmarks for translational therapeutic research.

Deciphering the Photocatalysis Mechanism of Semimetallic Bismuth Nanoparticles.

J Phys Chem C Nanomater Interfaces

November 2024

Department of Chemistry and Biochemistry, University of North Carolina Asheville, 1 University Heights, Asheville, North Carolina 28804, United States.

Metallic nanoparticle photocatalysts have been developed in various catalytic systems over the past few decades, including diverse noble and non-noble metals with plasmonic properties. The hot-carrier-induced mechanism is one of the most appealing pathways as it can provide energetic electrons or holes for driving thermodynamically unfavorable reactions or increasing the reaction rate. In this work, we evaluate the photocatalytic performance of semimetallic bismuth nanoparticles and offer detailed mechanistic interpretations in terms of hot carriers and interband transitions.
