Melanophilin-induced primary cilia promote pancreatic cancer metastasis.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most malignant tumors because of its high metastatic ability. The glutamine (Gln)-deficient microenvironment contributes to PDAC metastasis; however, the underlying molecular mechanisms remain unclear. Here, we demonstrated that melanophilin (MLPH) promotes PDAC metastasis by inducing the regrowth of primary cilia.

Recombinant Thrombomodulin Domain 1 Modulates Macrophage Polarization and Enhances Healing in Corneal Alkali Burns.

Purpose: Corneal alkali burns are severe ocular injuries characterized by intense inflammation, tissue damage, and vision impairment, with current treatments often insufficient in restoring corneal function and clarity. This study aimed to evaluate the therapeutic effects of recombinant thrombomodulin domain 1 (rTMD1) in the treatment of corneal alkali burns, focusing on its impact on inflammation, tissue repair, fibrosis, and neovascularization.

Methods: A murine model of corneal alkali burn was utilized to investigate the therapeutic potential of rTMD1.

Eradication of Cancer Cells Using Doxifluridine and Mesenchymal Stem Cells Expressing Thymidine Phosphorylase.

Gene-directed enzyme prodrug therapy (GDEPT) has been developed over several decades as a targeted cancer treatment aimed at minimizing toxicity to healthy cells. This approach involves three key components: a non-toxic prodrug, a gene encoding an enzyme that converts the prodrug into an active chemotherapy drug, and a gene carrier to target cancer cells. In this study, the prodrug doxifluridine was enzymatically converted into the chemotherapy drug 5-fluorouracil via thymidine phosphorylase, using human mesenchymal stem cells (hMSCs) as delivery vehicles.

Mental and Physical Wellbeing of Carer-Employees in Canada.

Today, an increasing number of Canadian adults are providing unpaid care to their family members and friends while working full or part-time. We conducted a national survey of unpaid caregiving for older people in 2022 to learn who these people are, why they care, and to identify the social, economic, and health impacts of unpaid caregiving. Our findings show that many of these caregivers are also employees.

Wearable and implantable biosensors: mechanisms and applications in closed-loop therapeutic systems.

This review article examines the current state of wearable and implantable biosensors, offering an overview of their biosensing mechanisms and applications. We also delve into integrating these biosensors with therapeutic systems, discussing their operational principles and incorporation into closed-loop devices. Biosensing strategies are broadly categorized into chemical sensing for biomarker detection, physical sensing for monitoring physiological conditions such as pressure and temperature, and electrophysiological sensing for capturing bioelectrical activities.
