Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

One‐Pot Incorporation of Quantum Defects into Single‐Walled Carbon Nanotubes with Arylazo Sulfonates

Angewandte Chemie, EarlyView.
We present a photochemical strategy to create complex aromatic quantum defects in carbon nanotubes using arylazo sulfonates. It provides access to brighter carbon nanotubes without purification and simpler biofunctionalization. Abstract Single‐walled carbon nanotubes (SWCNTs) consist of a carbon monolayer and fluoresce in the near‐infrared (NIR, 800 ...

Infantile‐Onset Ascending Hereditary Spastic Paraplegia due to a Homozygous ALS2 Exons 24–25 Deletion: Expanding the Genotypic Spectrum

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a novel homozygous intragenic deletion in the ALS2 gene in an 8‐year‐old boy with Infantile‐onset Ascending Hereditary Spastic Paraplegia (IAHSP) and oculomotor apraxia, thereby contributing to the expanding genetic landscape of ALS2‐related disorders.

Long‐Read Genome Sequencing Establishes Biallelic Pathogenic Variants in DNM1 With Distinct Functional Effects as the Cause of Early Infantile Developmental and Epileptic Encephalopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous de novo and inherited biallelic pathogenic variants in DNM1 have been reported in association with autosomal dominant (AD) and autosomal recessive (AR) developmental and epileptic encephalopathy, respectively, due to aberrant dynamin function or expression, with each inheritance pattern associated with a different mechanism of ...

Noonan Syndrome Spectrum Disorders Predispose to Systemic Lupus Erythematosus: Case Report and Critical Review of the Literature

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT RASopathies are clinically overlapping neurodevelopmental syndromes resulting from germline mutations in genes involved in the rat sarcoma/mitogen‐activated protein kinases (RAS/MAPK) pathway. Historically, RASopathies have been described by clinical phenotypes, such as Noonan syndrome and Neurofibromatosis type I.

Epstein–Barr Virus, Lower Vitamin D, Low Sun Exposure, and HLA‐DRB1*1501 Risk Variant Share Common Epigenetic Pathways Leading to Multiple Sclerosis Onset

Annals of Neurology, EarlyView.
Objectives Multiple sclerosis (MS) onset risk factors include Epstein–Barr virus (EBV) indices (including host response), lower serum 25‐vitamin D (25(OH)D) levels, low sun exposure, and HLA‐DRB1*1501. The underlying molecular mechanisms are unclear. Here, we examined mediation through differential DNA methylation (DNAm) to better understand possible ...

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...
