Triple-negative breast cancers (TNBCs) typically have a greater immune cell infiltrate and are more likely to respond to immune checkpoint inhibition (ICI) than ER+ or HER2+ breast cancers. However, there is a crucial need to optimize combining chemotherapy strategies with ICI to enhance overall survival in TNBC. Therefore, we developed a high-throughput co-culture screening assay to identify compounds that enhance CD8+ T-cell-mediated tumor cell cytotoxicity.

In this work, we evaluated two closo-borate salts (LiBH and LiBF) in propylene carbonate from theoretical and experimental perspectives to understand how the coordination environment influences their spectroscopic and electrochemical properties. The coordination environments of the closo-borate salts were modeled via density functional theory (DFT) and molecular dynamics (MD). Vibrational spectra calculated from the predicted coordination environments are in agreement with experimentally measured steady-state FTIR data.

Three-dimensional (3D) printer technology has seen a surge in use in medicine, particularly in orthopedics. A recent area of research is its use in peripheral nerve repair, which often requires a graft or conduit to bridge segmental defects. Currently, nerve gaps are bridged using autografts, allografts, or synthetic conduits.

Indigenous children and adolescents experience life circumstances that significantly affect their social and emotional well-being (SEWB) and limit their capacity to fulfil their potential. This contributes to inequities in health, education, employment, and justice system involvement. We aimed to synthesise the existing literature to comprehensively understand the protective and risk factors for SEWB of Indigenous youth in Canada, Australia, New Zealand, and the United States (CANZUS).

Background: Manual screening of a Kato-Katz (KK) thick stool smear remains the current standard to monitor the impact of large-scale deworming programs against soil-transmitted helminths (STHs). To improve this diagnostic standard, we recently designed an artificial intelligence based digital pathology system (AI-DP) for digital image capture and analysis of KK thick smears. Preliminary results of its diagnostic performance are encouraging, and a comprehensive evaluation of this technology as a cost-efficient end-to-end diagnostic to inform STH control programs against the target product profiles (TPP) of the World Health Organisation (WHO) is the next step for validation.

Background: The increasing incidence of breast cancer and disease burden is a significant public health concern. While 30% of breast cancers could be prevented through addressing modifiable risk factors, misconceptions among women about breast cancer risks hamper primary prevention. In the absence of primary prevention, secondary prevention such as mammography increases the early detection of breast cancer and improves health outcomes.

Article Synopsis
  • A study in Ucayali, Peru examined two methods for detecting soil-transmitted helminth infections in children: the old method called Kato-Katz (KK1.0) and a new method using artificial intelligence called KK2.0.
  • The researchers analyzed stool samples from 510 kids aged 5-14 and found that KK2.0 could detect more cases of Ascaris lumbricoides compared to KK1.0, especially at the 30-minute mark.
  • The results showed that while both methods had similar detection rates for other types of infections, KK2.0 was better at finding low levels of A. lumbricoides infection in the kids.

Polyergus kidnapper ants are widely distributed, but relatively uncommon, throughout the Holarctic, spanning an elevational range from sea level to over 3000 m. These species are well known for their obligate social parasitism with various Formica ant species, which they kidnap in dramatic, highly coordinated raids. Kidnapped Formica larvae and pupae become integrated into the Polyergus colony where they develop into adults and perform nearly all of the necessary colony tasks for the benefit of their captors.
