Immunohistochemistry for PRAME in the Distinction of Nodal Nevi From Metastatic Melanoma

American Journal of Surgical Pathology, 2019
The distinction of metastatic melanoma from melanocytic nevi in lymph nodes can on occasion be difficult. As diffuse immunohistochemical (IHC) PRAME (PReferentially expressed Antigen in MElanoma) expression is detected in the majority of primary and ...

Non-Abelian topology of nodal-line rings in PT -symmetric systems [PDF]

Physical review B, 2019
Nodal lines inside the momentum space of three-dimensional crystalline solids are topologically stabilized by a π flux of Berry phase. Nodal-line rings in PT-symmetric systems with negligible spin-orbit coupling (here described as “nodal class AI”) can ...

Durability of Response to B‐Cell Maturation Antigen‐Directed mRNA Cell Therapy in Myasthenia Gravis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We report the 12‐month follow‐up outcomes from a Phase 2 clinical trial (NCT04146051) evaluating Descartes‐08, a BCMA‐directed RNA chimeric antigen receptor T‐cell (rCAR‐T) therapy for refractory generalized myasthenia gravis (MG).

Nerve Excitability in Asymptomatic Carriers and Amyotrophic Lateral Sclerosis Patients With C9orf72

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We investigated the effects of C9orf72 mutation carriership on peripheral nerve excitability in asymptomatic individuals from families with a history of C9orf72 amyotrophic lateral sclerosis (ALS) and patients. Methods We included 47 asymptomatic individuals from families with a history of C9orf72 ALS, of whom 23 were carriers (C9 ...

Constant-Parameter Average-Value Model of Power-Electronic Voltage-Source Converters With Direct Interface in Electromagnetic Transient Simulators

IEEE Open Journal of Power Electronics
Average-value models (AVMs) of voltage-source converters (VSCs) are widely used as numerically efficient alternatives to their discrete switching models in electromagnetic transient (EMT) simulations. Recently, a so-called directly-interfaced AVM (DI-AVM)

Programmable Reconfiguration of Hybrid 4D Chiral Metamaterials via Mechanical and Thermal Stimuli

Advanced Engineering Materials, EarlyView.
A class of hybrid chiral mechanical metamaterials is designed to achieve programmable reconfiguration through soft networks, hinges, and bilayer joints integrated with rigid units. Responsive to mechanical and thermal stimuli, these structures exhibit large volume changes, tunable deformation pathways, and both positive and negative thermal expansion ...

The Characteristics and Patterns of Drug-Resistant Pulmonary Tuberculosis in Eastern India

Tropical Medicine and Infectious Disease, 2022
Background: Drug-resistant tuberculosis is a major public health problem throughout the world and accounts for substantial morbidity and mortality rates in India, too. Early diagnosis is the corner stone of tuberculosis treatment. State-level and cluster-

Nodal rings and drumhead surface states in phononic crystals

Nature Communications, 2019
Three-dimensional topological nodal lines, the touching curves of two bands in momentum space, which give rise to drumhead surface states, provide an opportunity to explore a variety of exotic phenomena.
