Monomelic amyotrophy (MMA) is a lower motor neuron predominant disorder affecting an upper limb, which can mimic amyotrophic lateral sclerosis (ALS). It often presents with unilateral, distal upper limb weakness and atrophy, whose trajectory is one of an initial period of progression followed by a prolonged plateau, as opposed to the typically relentless progression as is seen in ALS. This case report describes a novel observation of a patient with MMA with an unexplained ipsilateral partial Horner's syndrome (miosis and ptosis).

Introduction: Blue light (peak wavelength 442 nm) has been shown to modulate the immune response in preclinical models of intra-abdominal sepsis and pneumonia. pathways involve optic nerve stimulation with transmission to the central nervous system, activation of parasympathetic pathways terminating at the spleen, and downstream immune effects including decreased inflammatory tissue damage and improved pathogen clearance. Related effects on pain mediators including proinflammatory cytokines (interleukin 6, TNF- α) and autonomic tone (increased parasympathetic outflow) suggest possible analgesic properties that would be highly relevant to a trauma population.

National Laboratory of Solid State Microstructures, School of Electronic Science and Engineering and Collaborative Innovation Center of Advanced Microstructures, Nanjing University, Nanjing 210093, China.

Two-dimensional (2D) materials offer strong light-matter interaction and design flexibility beyond bulk semiconductors, but an intrinsic limit is the low absorption imposed by the atomic thickness. A long-sought-after goal is to achieve complementary absorption enhancement through energy transfer (ET) to break this limit. However, it is found challenging due to the competing charge transfer (CT) process and lack of resonance in exciton states.

The neuronal ceroid lipofuscinoses (NCLs), more commonly known as Batten disease, are a group of fatal inherited neurodegenerative lysosomal storage disorders. Each form is caused by mutations in a different gene, resulting in lysosomal dysfunction, which, by largely unknown mechanisms, has a devastating impact on the central nervous system. The NCLs are grouped together owing to their broadly shared clinical presentations and the presence of autofluorescent storage material.

In ovarian cancer, resistance to conventional treatments has prompted the search for alternative targets and/or cells within the tumor microenvironment (TME) that could enhance tumor cell death. Ferroptosis, an iron-dependent, lipid peroxide-triggered form of cell death, is one such pathway. Cancer‑associated fibroblasts (CAFs) are key stromal cells in the ovarian TME that can impact therapeutic responses.

Human diseases caused by homozygous PTH1R mutations.

Front Endocrinol (Lausanne)

September 2025

Endocrine Unit, Massachusetts General Hospital, and Harvard Medical School, Boston, MA, United States.

The parathyroid hormone receptor type 1 (PTH1R) is a G protein-coupled receptor that mediates the actions of parathyroid hormone (PTH) in the regulation of blood calcium levels, as well as PTH-related protein (PTHrP) in the regulation of skeletal development. Severe loss-of-function homozygous mutations in PTH1R are incompatible with life as in Blomstrand's lethal chondrodysplasia, characterized by accelerated growth plate ossification. More recently, homozygous mutations located in the transmembrane helices, extracellular domains and C-tail of the PTH1R were identified in patients with milder conditions characterized by variable degrees of skeletal and mineral abnormalities.

From pathogens and computer viruses to genes and memes, contagion models have found widespread utility across the natural and social sciences. Despite their success and breadth of adoption, the approach and structure of these models remain surprisingly siloed by field. Given the siloed nature of their development and widespread use, one persistent assumption is that a given contagion can be studied in isolation, independently from what else might be spreading in the population.

An SRR1 domain-containing protein is required for efficient Orsay virus replication in .

J Virol

September 2025

Department of Molecular Microbiology, School of Medicine, Washington University in St. Louis, St. Louis, Missouri, USA.

Viruses depend on their hosts for completing their life cycle, and a better understanding of virus replication can inform therapeutic strategies. Using the Orsay virus- experimental platform, we identified by a forward genetic screen the host gene (renamed ) as a novel host factor critical for Orsay virus replication. Three distinct mutations of each resulted in a >1,000-fold reduction in Orsay viral load, demonstrating a pro-viral function of had no previously described function in , but in the absence of viral infection, deletion of the locus by CRISPR/Cas9 led to a reduction in brood size and a shortened lifespan.

In this work, we show that the combination of radiation therapy (RT) and an IL15/IL15Rα fusion complex (denoted IL15c) fails to confer anti-tumor efficacy; however, a CD8-driven anti-tumor immune response can be elicited with the concurrent administration of an aCD25 Treg-depleting antibody. Using IL15-/- and Rag1-/- knockout mouse models, we show that the response to RT + IL15c + aCD25 is dependent on both IL15 and CTLs. Furthermore, despite an equivalent survival benefit following treatment with RT + IL15c + aCD25 and combination RT and PD1-IL2v, a novel immunocytokine with PD-1 and IL2Rbg binding domains, CTL immunophenotyping and phospho-proteomic analysis of intracellular metabolites showed a significant upregulation of activation and functionality in CD8 T cells in the RT + PD1-IL2v regimen.

Sclerostin, a key regulator of Wnt/β-catenin signaling, exhibits dual therapeutic potential in bone disorders: its inhibition promotes bone formation in osteoporosis, while its mimicry suppresses aberrant bone growth in osteoarthritis (OA). Using structural insights from NMR studies, we identified two sclerostin-derived peptides: SC-1 (an 18-mer) from loop 2, and SC-3 (a 14-mer) from loop 3. Molecular modeling showed that SC-1 binds to the first ectodomain of LRP6, potentially displacing sclerostin through competitive inhibition to activate Wnt signaling.
