Genome sequencing has identified numerous mutations in the DEAD‐box RNA helicases, DDX3X and DDX3Y, associated with cancer and other diseases, but monitoring of their functional consequences remains a challenge. Conventional helicase assays are laborious, often technically difficult, and are performed in cell‐free systems that do not address biologically relevant questions. Here, we developed an engineered

Photodynamic therapy (PDT) is a minimally invasive treatment that involves the administration of a light‐activatable drug followed by light activation of the lesion to produce reactive oxygen species that kill cancer cells. Visudyne®, a liposomal formulation of benzoporphyrin derivative (BPD) photosensitizer, is clinically approved for PDT of ocular diseases and is now being tested for PDT and imaging

One way to address the growing shortage of donated blood required for routine and emergency transfusion is to mass‐manufacture red blood cells (RBCs) in vitro. However, numerous biological and bioprocessing challenges must be overcome to realize this goal. In addressing these challenges, a promising solution is the erythroid progenitor cell line, BEL‐A (Bristol Erythroid Line—Adult). Despite this,

Spinal cord injury (SCI) triggers an immediate influx of immune cells that secrete pro‐inflammatory cytokines and reactive oxygen species that cause tissue damage that is secondary to the initial physical trauma. We aim to reprogram these immune cells to promote a less inflammatory and more pro‐regenerative environment. Herein, we investigated the window in time during which poly(lactide‐co‐glycolide)

Malignant cerebral edema (MCE) represents a significant medical emergency characterized by unmanageable intracranial pressure (ICP), frequently arising as a consequence of traumatic brain injury (TBI) or ischemic stroke. Decompressive craniectomy (DC) is a prevalent surgical procedure employed to mitigate elevated ICP by excising a segment of the skull to enhance intracranial volume. Nevertheless,

Bacteriophages are considered ideal vaccine platforms owing to their safety, intrinsic adjuvant properties, stability, and low‐cost production. One of the best strategies to prevent brucellosis in humans and animals is vaccination.

Using TCGA and GEO databases

Lentiviral vectors (LVVs) are emerging as an enabling tool in gene and cell therapies, yet the toolkit for purifying them at scale is still immature. A pivoting moment in LVV isolation technology was marked by the introduction of affinity ligands for LVVs pseudo‐typed with Vesicular Stomatitis Virus G (VSV‐G) protein. Camelid antibody ligands were initially discovered and utilized to functionalize

Nipple reconstruction in patients who undergo total mastectomy or nipple‐sparing mastectomy is currently limited by a consistent and significant loss of nipple projection over time, which can negatively affect patient satisfaction and quality of life. To address this issue, we have previously shown that 3D‐printed poly‐4‐hydroxybutyrate (P4HB) nipple‐shaped scaffolds promote long‐term maintenance of

Adalimumab (Humira) represents a major advance in rheumatoid arthritis (RA) therapy. However, with long‐term administration of Adalimumab, anti‐idiotypic antibody (anti‐Id Ab) accelerates the Adalimumab clearance rate and reduces the therapeutic effect. To avoid the interference of anti‐Id Ab, we used an autologous hinge region as a spatial‐hindrance‐based Ab lock and connected it to the N‐terminal

Colorectal precancerous lesions (CRP) are early signs of cancer development, and early detection helps prevent progression to colorectal cancer (CRC), reducing incidence and mortality rates. This study developed a serum detection platform integrating surface‐enhanced Raman scattering (SERS) with machine learning (ML) for early detection of CRP. Specifically, a microarray chip with Au/SnO2 nanorope

Atherosclerosis is a chronic, systemic, inflammatory disease associated with the build‐up of fatty deposits (“plaques”) in the arteries. A major global health burden, severe atherosclerosis progresses to ischemic heart disease, an underlying condition which can exacerbate the occurrence of fatal events such as heart attack and stroke. Over the past two decades, the use of in vitro models to study atherosclerotic

Managing delivery of complex multidrug infusions in anesthesia and critical care presents a significant clinical challenge. Current practices relying on manual control of infusion pumps often result in unpredictable drug delivery profiles and dosing errors—key issues highlighted by the United States Food and Drug Administration (FDA). To address these issues, we introduce the SMART (synchronized‐pump

Hypertrophic scar (HS) is one of the most common complications of skin injuries, with a lack of effective therapeutic approaches to date. Most current research has focused on the dysfunction of hypertrophic scar fibroblasts (HSFBs) and dermal vascular endothelial cells (HDVECs), neglecting the crucial role of the inflammatory microenvironment that causes them to be abnormal. In this study, we first

Rapid restoration of blood flow is critical in treating acute ischemic stroke. Current thrombolytic therapies using tissue plasminogen activator (tPA) are limited by low recanalization rates and risks of off‐target bleeding. Here, we demonstrate that a remarkably simple adjustment—using micrometer‐scale rather than sub‐micrometer particles to immobilize tPA—fundamentally improves thrombolysis. By merely

Volumetric muscle loss is the significant loss of skeletal muscle volume beyond the innate regenerative capacity, resulting in functional impairment. The current standard of care combines muscle autografting with physical therapy but is often insufficient to reach full recovery. Decellularized skeletal muscle (DSM) provides an interesting alternative to repair volumetric muscle loss. The native structure

The microvascular basement membrane (mvBM) is crucial in maintaining vascular integrity and function and, therefore, key to the health of major organs. However, the complex nature and the intricate interplay of biochemical and biomechanical factors that regulate the mvBM functional dynamics make it difficult to study.

Human Mpox disease (MPX) is an endemic zoonotic disease that develops when patients are infected with the Mpox virus (MPXV). MPXV shares a high level of genetic similarity to other poxviruses and the clinical presentation of MPX is similar to other poxvirus infections which can result in a delay in diagnosis. In addition, the MPXV virus is phylogenetically divided into two different clades which affects

Recent studies show that tumor cells undergo apoptosis after mechanical stretching, which promotes normal cell growth.
