Human mobility and malaria risk in peri-urban and rural communities in the Peruvian Amazon.

Background: While the global burden of malaria cases has decreased over the last two decades, the disease remains a major international threat, even on the rise in many regions. More than 85% of Peruvian malaria cases are in the Amazonian region of Loreto. Internal mobility primarily related to occupation is thought to be primarily responsible for maintaining endemicity and introducing and reintroducing malaria parasites into areas of anophelism, a challenge for malaria eradication.

Exploring the Unique Role of Specialized Pro-Resolving Mediators in Cancer Therapeutics.

Unresolved chronic inflammation, a hallmark of cancer, promotes tumor growth and metastasis in various cancer types. In contrast to blocking inflammation, stimulation of resolution of inflammation is an entirely novel approach to "resolve" inflammation. Resolution of inflammation mechanisms in cancer includes clearance of tumor debris, counter-regulation of pro-inflammatory eicosanoids and cytokines, and suppression of leukocyte infiltration.

Plasma DNA Methylation-Based Biomarkers for MPNST Detection in Patients With Neurofibromatosis Type 1.

Malignant peripheral nerve sheath tumor (MPNST) development is characterized by an altered DNA methylation landscape, which presents a promising area for developing MPNST-specific biomarkers for screening patients with NF1. Genome-wide DNA methylation profiling of a cohort of 13 patients with MPNST (29 samples of tumor and adjacent neurofibroma tissues) and of NF1-MPNST cell lines was performed to identify and validate candidate MPNST-specific CpG sites (CpGs). A logistic regression prediction model was constructed to select MPNST-specific CpGs distinct from adjacent neurofibromas and normal tissues.

Targeting the Galectin-1/Ras Interaction for Treating Malignant Peripheral Nerve Sheath Tumors.

Background: Neurofibromatosis type 1 (NF1) is a common inherited neurological disorder that can lead to the development of malignant peripheral nerve sheath tumors (MPNSTs), a highly aggressive form of sarcoma. Current treatment options for MPNSTs are limited, with poor prognosis and high recurrence rates. This study aims to explore the potential of targeting the Galectin-1 (Gal-1) and Ras interaction as a novel therapeutic strategy for MPNSTs.

Recurrence patterns and evolution of submicroscopic and asymptomatic Plasmodium vivax infections in malaria-endemic areas of the Peruvian Amazon.

Background: In the Peruvian Amazon, Plasmodium vivax malaria transmission is maintained due to the high frequency of recurrences. By understanding the recurrence rates of submicroscopic and asymptomatic cases, we can develop informed strategies to prevent transmission more efficiently and disrupt the silent transmission cycle.

Methods: A three-year, population-based cohort study was conducted in two sites, Cahuide and Lupuna, within the Loreto region in Peru from 2013 to 2015.

An engineered ultrahigh affinity bi-paratopic uPAR targeting agent confers enhanced tumor targeting.

Urokinase-type plasminogen activator receptor (uPAR) is overexpressed on tumor cells in multiple types of cancer and contributes to disease progression and metastasis. In this work, we engineered a novel bi-paratopic uPAR targeting agent by fusing the binding domains of two native uPAR ligands: uPA and vitronectin, with a flexible peptide linker. The linker length was optimized to facilitate simultaneous engagement of both domains to their adjacent epitopes on uPAR, resulting in a high affinity and avid binding interaction.
