The Role of Innate Priming in Modifying Tumor-associated Macrophage Phenotype.

Front Biosci (Landmark Ed)

December 2024

Mackenzie Cancer Research Group, Department of Pathology and Biomedical Science, University of Otago Christchurch, 8011 Christchurch, Aotearoa New Zealand.

Tumor-associated macrophages (TAMs) are innate immune cells that exert far reaching influence over the tumor microenvironment (TME). Depending on cues within the local environment, TAMs may promote tumor angiogenesis, cancer cell invasion and immunosuppression, or, alternatively, inhibit tumor progression via neoantigen presentation, tumoricidal reactive oxygen species generation and pro-inflammatory cytokine secretion. Therefore, TAMs have a pivotal role in determining tumor progression and response to therapy.

Introduction: Cephalosporins can trigger hypersensitivity reactions in certain individuals. Consequently, strict regulations restrict the production of non-beta-lactam substances during or after cephalosporin manufacturing. Dry chlorine dioxide gas (dClO), together with ultra-performance liquid chromatography Mass spectrometry/mass spectrometry (UPLC-MS/MS) detection methods, has emerged as a promising method for decontaminating cephalosporin compounds.

Heat accumulation due to repetitive simple laser processing paths during building up a three-dimensional structure is a well-known issue that needs to be settled to reduce the excessively high residual stress and thermal deformation in a powder bed fusion (PBF) additive manufacturing process. Because of the dependency of laser path on the thermal dispersion, it is essential to analyze the heat accumulation phenomenon during laser processing. A computational fluid dynamics (CFD) analysis based on the volume of fraction method is used to optimize the laser path for minimizing the local heating up in the PBF process.

This paper examines the dynamics of 'irregularly regulated markets', specifically those dealing with what we term 'criminogenic collectables': antiquities, fossils, and wildlife. Through the lens of 'irregular regulation' we consider how inconsistencies and loopholes in legal frameworks contribute to criminal activities in these markets. We outline five ways that such markets can be considered irregular: socially, jurisdictionally, temporally, culturally and discursively.

Background: The gold standard of care for patients with severe peripheral nerve injury is autologous nerve grafting; however, autologous nerve grafts are usually limited for patients because of the limited number of autologous nerve sources and the loss of neurosensory sensation in the donor area, whereas allogeneic or xenografts are even more limited by immune rejection. Tissue-engineered peripheral nerve scaffolds, with the morphology and structure of natural nerves and complex biological signals, hold the most promise as ideal peripheral nerve "replacements".

Aim: To prepare allogenic peripheral nerve scaffolds using a low-toxicity decellularization method, and use human umbilical cord mesenchymal stem cells (hUC-MSCs) as seed cells to cultivate scaffold-cell complexes for the repair of injured peripheral nerves.

This review describes and evaluates the representation of women in cardiovascular randomized controlled trials (RCT), it reports significant under-representation of women in clinical trials both as participants and researchers and discusses the ethical implications of under-representation. The under-representation of women as participants in cardiovascular RCTs is evident in trials investigating cardiovascular drugs, acute coronary syndrome, heart failure and interventional procedures and devices. Under-representation of women is also evident in the authorship of cardiovascular clinical trials and in trial leadership roles, and under-representation of women as trial investigators is independently associated with under- recruitment of women as trial participants.
