Gender-typed play may contribute to gender disparities in spatial skills, but evidence of this link is limited. Gender-typed play and mental transformation, an important spatial skill, were studied using age-appropriate and comprehensive measures. Chinese children were tested at 5-6 years and at 11-14 years (N = 210), creating a long-term data set considering bidirectional associations.

Vivianite, a notable secondary mineral formed through dissimilatory iron reduction (DIR), demonstrates great potential in addressing both eutrophication and phosphorus deficiency. However, the presence of competition for electrons from the methanogenic pathway and the low rates of Fe(III) reduction limit the creation of vivianite. In this research, H was utilized as electron donor assisted by activated carbon (AC) to promote Fe(Ⅲ) reduction with FePO as electron acceptors.

As the role of RNA modification in gene expression regulation and human diseases, the "epitranscriptome" has been shown to be an important player in regulating many physiological and pathological processes. Meanwhile, the phenomenon of cancer drug resistance is becoming more and more frequent, especially in the case of cancer chemotherapy resistance. In recent years, research on relationship between post-transcriptional modification and cancer including drug resistance has become a hot topic, especially the methylation of the sixth nitrogen site of RNA adenosine-mA (N6-methyladenosine).

Article Synopsis
  • Repairing large bone defects involves complex processes where different cell types interact to regenerate bone, making it a complex but interesting area of study.
  • Exosomes, tiny vesicles that help cells communicate, play a crucial role in this repair process and have emerged as a promising treatment option due to their effective properties and ability to minimize immune reactions.
  • This study found that exosomes from a specific cell type (Krt14Ctsk) significantly boost the growth and migration of blood vessel cells, enhance bone formation markers, and improve healing in bone defects, indicating their potential for advancing bone repair therapies.

Article Synopsis
  • - The study focuses on creating a predictive nomogram for Klebsiella pneumoniae liver abscess (KPLA), a serious health issue primarily affecting Asia, using clinical and radiomics data from 255 patients with pyogenic liver abscess (PLA).
  • - Researchers divided the patients into training and validation groups and analyzed various clinical features and imaging data, ultimately identifying key predictors and developing a nomogram that incorporates both clinical and radiomics scores for better prediction accuracy.
  • - The nomogram demonstrated strong predictive performance with an area under the curve (AUC) of around 0.93 in both patient groups, indicating its effectiveness for early diagnosis of KPLA, which could lead to improved patient outcomes.

Article Synopsis
  • A highly valuable medicinal plant in China is suffering from replant disease, which is caused by factors like allelochemicals and microbes that create complex stress conditions.
  • This study established different treatments to investigate the plant's response to replant disease using sRNA-seq technology, leading to the identification of 201 miRNAs, with notable differences in expression profiles between continuously planted and normally planted samples.
  • The research found that certain miRNAs are downregulated in replant disease, hindering plant growth, while others that are upregulated can negatively affect root formation and nutrient metabolism, contributing to oxidative stress in the plant.

Background: The involvement of the larynx in many situations can have a substantial impact on a person's voice, breathing, and general health. Individuals with autoimmune thyroid disorders can experience a variety of conditions affecting the larynx. Autoimmune thyroid disorders, such as Hashimoto's thyroiditis [HT] and Graves' disease [GD], are prevalent conditions affecting the thyroid gland.

The exponential rise in metabolic dysfunction-associated steatotic liver disease (MASLD) parallels the ever-increasing consumption of energy-dense diets, underscoring the need for effective MASLD-resolving drugs. MASLD pathogenesis is linked to obesity, diabetes, "gut-liver axis" alterations, and defective interleukin-22 (IL-22) signaling. Although barrier-protective IL-22 blunts diet-induced metabolic alterations, inhibits lipid intake, and reverses microbial dysbiosis, obesogenic diets rapidly suppress its production by small intestine-localized innate lymphocytes.

Article Synopsis
  • - The MYB family of transcription factors, particularly the R2R3-MYB subfamily, plays a significant role in plant development and the production of secondary metabolites like flavonoids.
  • - A comprehensive study on Artemisia argyi identified 92 R2R3-MYB transcription factors and predicted their functions, revealing they are primarily hydrophilic proteins located in the nucleus, with some found in both the nucleus and cytoplasm.
  • - Expression analysis indicated that certain R2R3-MYB factors are predominantly active in leaves, and five key transcription factors were selected as candidates for their role in flavonoid synthesis and glandular trichome development, aiding future breeding efforts.

Ubiquitin (Ub) is a post-translational modification that largely controls proteostasis through mechanisms spanning transcription, translation, and notably, protein degradation. Ub conjugation occurs through a hierarchical cascade of three enzyme classes (E1, E2, and E3s) involving >1000 proteins that regulate the ubiquitination of proteins. The E2 Ub-conjugating enzymes are the midpoint, yet their cellular roles remain under-characterized, partly due to a lack of inhibitors.

Article Synopsis
  • Machine learning algorithms are used for counting people in crowds, and test-time adaptation methods help models adjust to specific conditions during testing by altering model parameters and using additional data augmentation.
  • Unlike traditional methods that require extensive unannotated data for each new target domain, the proposed CrowdTTA approach combines test-time adaptation with meta-learning for better adaptability in unknown conditions.
  • CrowdTTA generates pseudo labels using uncertainty from a dropout layer, facilitating dual-level optimization which improves model performance and accuracy in counting people under various crowd densities and scales during testing.

Background: Chronic cough in children is closely related to gastroesophageal reflux (GER). However, this association has not been adequately studied due to a lack of diagnostic tools. Combined esophageal multichannel intraluminal impedance and pH (MII-pH) monitoring is considered the most accurate method for evaluating the association between symptoms and reflux, but data on its use in children with chronic cough are still lacking.
