Background: OnabotA is used to treat masseter muscle prominence (MMP).

Objective: To assess the safety and efficacy of OnabotA for MMP in a randomized study.

Methods: This 12-month, multicenter, double-blind, placebo-controlled, phase 2 study randomized adults (18-50 years of age) with marked/very marked bilateral MMP (≥4 on the Masseter Muscle Prominence Scale [MMPS]) to OnabotA (24, 48, 72, or 96 U) or placebo; retreatment occurred at day 180 if MMPS ≥4.

Article Synopsis
  • The study investigates the impact of hydrogen incorporation in layered superconducting nickelate films and its potential link to superconductivity.
  • Films are created by converting a stable parent compound into the desired phase using a reducing agent like CaH, but achieving highly crystalline nickelate films remains challenging.
  • Findings show that hydrogen incorporation is minimal across various samples, both superconducting and non-superconducting, suggesting that it’s not essential for achieving superconductivity in these nickelate systems.

Inflammation is essential to the disruption of tissue homeostasis and can destabilize the identity of lineage-committed epithelial cells. Here, we employ lineage-traced mouse models, single-cell transcriptomic and chromatin analyses, and CUT&TAG to identify an epigenetic memory of inflammatory injury in the pancreatic acinar cell compartment. Despite resolution of pancreatitis, our data show that acinar cells fail to return to their molecular baseline, with retention of elevated chromatin accessibility and H3K4me1 at metaplasia genes, such that memory represents an incomplete cell fate decision.

The process of vaccine production, manufacturing, is time-intensive, complex, expensive, and highly technical, requiring close coordination and collaboration among multiple companies with different inputs, from active pharmaceutical ingredients to glass, and specializations, and with the supply chains spread across many countries. Covid-19 pandemic highlighted that neglecting and ignoring the need for a global effort in vaccine manufacturing and delivery can have alarming, and devastating, repercussions, especially when the world needs a robust healthcare ecosystem to make sure that all of us are safe. So, the natural question is: what does the world need to be well-prepared for the next virus; what does it take to have the manufacturing of vaccines become less concentrated in a few countries and centers and diversified to more countries so that distribution can be more universal, so that all of us are safe? First will need to be the political recognition, and the acceptance, that no country can do or supply everything alone in the pharmaceutical sector - no country can be an island -and that binding international agreements will need to be adopted to make access to medicine more equitable and secure around the world.

Non-collinear antiferromagnets (AFMs) are an exciting new platform for studying intrinsic spin Hall effects (SHEs), phenomena that arise from the materials' band structure, Berry phase curvature, and linear response to an external electric field. In contrast to conventional SHE materials, symmetry analysis of non-collinear antiferromagnets does not forbid non-zero longitudinal and out-of-plane spin currents with polarization and predicts an anisotropy with current orientation to the magnetic lattice. Here, multi-component out-of-plane spin Hall conductivities are reported in L1 -ordered antiferromagnetic PtMn thin films that are uniquely generated in the non-collinear state.

The layered square-planar nickelates, NdNiO, are an appealing system to tune the electronic properties of square-planar nickelates via dimensionality; indeed, superconductivity was recently observed in NdNiO thin films. Here, we investigate the role of epitaxial strain in the competing requirements for the synthesis of the n = 3 Ruddlesden-Popper compound, NdNiO, and subsequent reduction to the square-planar phase, NdNiO. We synthesize our highest quality NdNiO films under compressive strain on LaAlO (001), while NdNiO on NdGaO (110) exhibits tensile strain-induced rock salt faults but retains bulk-like transport properties.

Since the discovery of high-temperature superconductivity in copper oxide materials, there have been sustained efforts to both understand the origins of this phase and discover new cuprate-like superconducting materials. One prime materials platform has been the rare-earth nickelates and, indeed, superconductivity was recently discovered in the doped compound NdSrNiO (ref. ).

Article Synopsis
  • Researchers developed short ceramide analogs that can be activated by light and modified using click chemistry.
  • These analogs have better cell permeability than longer versions, proven by mass spectrometry and imaging techniques.
  • The short analogs allow for optical control of apoptosis and serve as light-responsive substrates for sphingomyelin synthase 2, showing reversed light dependency compared to longer variants.

Recent renewed interest in layered transition metal dichalcogenides stems from the exotic electronic phases predicted and observed in the single- and few-layer limit. Realizing these electronic phases requires preserving the desired transport properties down to a monolayer, which is challenging. Surface oxides are known to impart Fermi level pinning or degrade the mobility on a number of different systems, including transition metal dichalcogenides and black phosphorus.

Background: Despite the increasing popularity of hookah bars, there is a lack of research assessing the health effects of hookah smoke among employees. This study investigated indoor air quality in hookah bars and the health effects of secondhand hookah smoke on hookah bar workers.

Methods: Air samples were collected during the work shift of 10 workers in hookah bars in New York City (NYC).
