We examine peer violence trajectories among a purposive sample of urban poor adolescents over 3 years in Kinshasa, Democratic Republic of Congo (DRC); Shanghai, China, and Bandar Lampung, Denpasar, and Semarang, Indonesia. We examine peer violence experiences over time and seek to understand the relationship between gender norm perceptions and personal agency on peer violence experiences. A longitudinal (wave 1-3) panel was used from the three study sites outlined above ( = 6,660).

Interleukin-10 receptor subunit alpha (IL-10RA), a member of the type II cytokine receptor family, is predominantly expressed on macrophages and T cells and plays a crucial role in regulating immune cell metabolism and immune response. However, its role in the energy metabolic pathways of tumor cells remains unclear.

Damage to the blood-brain barrier (BBB) is implicated in anxiety, but its regulatory mechanisms remain unclear. Herein, we show that adrenomedullin 2 (ADM2), a novel angiogenic growth factor, alleviates autistic and anxiety-like behaviors in mice.

Identifying key molecules that enhance BC cells' cisplatin sensitivity can help improve the clinical efficacy of BC treatment. Hence, this study aimed to determine the expression level of long non-coding RNA (lncRNA) ADAM Metallopeptidase with Thrombospondin Type 1 Motif 9 Antisense RNA 1 () in BC and explore its related mechanism underlying the amplification of cisplatin sensitivity.

Methods: The study was based on focus group discussion data from 9 urban poor communities in Kinshasa (Democratic Republic of Congo), Blantyre (Malawi), Shanghai (China), Semarang and Denpasar (Indonesia), New Orleans (USA), Ghent (Belgium), São Paulo (Brazil), and Santiago (Chile). Translated transcripts from the focus group discussions were uploaded into ATLAS.
Cisplatin resistance in ovarian cancer cells is mainly apoptosis resistant. Although other types of programmed cell death are highly involved in chemoresistance, which type can overcome cisplatin resistance remains unclear. The present study observed that cisplatin-sensitive SKOV3 cells and cisplatin-resistant SKOV3/DDP cells had different levels of sensitivity to sulfasalazine (SAS).

Over recent years, the hybrid Problem-Based Learning (hPBL) model, a blend of Problem-Based Learning (PBL) and Lecture-Based Learning (LBL), has emerged as a novel approach in the medical education reform landscape of China. The application and efficacy of the hPBL model in medical experimental courses have piqued the interest of medical educators.

Metabolic dysfunction-associated steatotic liver disease (MASLD) affects approximately 25% of the world's population and has become a leading cause of chronic liver disease. In recent years, an increasing amount of data suggests that MASLD is associated with aging. As the population ages, age-related MASLD will become a major global health problem.

Ovarian cancer (OVCA) is a representative adipocyte‑rich associated cancer. In the present study, epithelial OVCA (EOC) was used to investigate the influence of ARM on chemoresistance with the aim of identifying novel targets and developing novel strategies to reduce chemoresistance.

However, its biological activity can be mediated by inducing conformational changes through interactions with specific certain small molecules and receptors. Nr4a3 is activated as an early stress factor under various pathological conditions and plays a regulatory role in various tissues and cells, participating in processes such as cell differentiation, apoptosis, metabolism, and homeostasis.

Hemostatic materials are of great significance for rapid control of bleeding, especially in military trauma and traffic accidents. Chitosan (CS) hemostatic sponges have been widely concerned and studied due to their excellent biocompatibility. However, the hemostatic performance of pure chitosan sponges is poor due to the shortcoming of strong rigidity.

The typical receptors for IMD are complexes composed of calcitonin receptor-like receptor (CLR) and receptor activity-modifying protein (RAMP), which leads to a biased activation towards Gα. As a diagnostic and prognostic biomarker, IMD regulates the initiation and metastasis of multiple tumors.
