Airway multiciliated cells (MCs) maintain respiratory health by clearing mucus and trapped particles through the beating of motile cilia. While it is known that ciliary lengths decrease along the proximal-distal (P-D) axis of the tracheobronchial tree, how this is regulated is unclear. Here, we demonstrate that canonical Notch signaling in MCs plays a critical role in stabilizing ciliary length.

Background: Vagal nerve denervation during the heart transplant procedure results in higher resting heart rates in these recipients compared to the general population. Relative bradycardia (RB) is a common and often temporary post-operative complication that can be managed with agents like terbutaline; however, little data exist on the efficacy, safety, and necessity of long-term terbutaline use post-heart transplant.

Methods: This was a single-center, retrospective, descriptive study conducted at a large academic medical center investigating oral terbutaline use for RB management in heart transplant recipients.

The protein corona formed on nanoparticles (NPs) has potential as a valuable diagnostic tool for improving plasma proteome coverage. Here, we show that spiking small molecules, including metabolites, lipids, vitamins, and nutrients into plasma can induce diverse protein corona patterns on otherwise identical NPs, significantly enhancing the depth of plasma proteome profiling. The protein coronas on polystyrene NPs when exposed to plasma treated with an array of small molecules allows for the detection of 1793 proteins marking an 8.

Background: Hypertrophic olivary degeneration (HOD) is a rare form of transsynaptic degeneration, caused by injury to the dentato-rubro-olivary pathway (DROP). Radiologically, this manifests as T2 hyperintensity, with or without enlargement of the inferior olivary nucleus. The purpose of the study was to evaluate the incidence, associated imaging characteristics, potential etiologies, latency period, and temporal progression of HOD in patients undergoing surgical resection of posterior fossa tumors (PFTs).

Pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries, paragangliomas, and syringomyelia are uncommon diseases. Furthermore, in the absence of any genetic link and with less than five reported adult patients surviving unrepaired rare form of Tetralogy of Fallot, our case shows noteworthiness. The possibility of definitive treatment of these conditions is rendered unsafe due to this persistent defect.

Article Synopsis
  • Tetrahedral carbon is a common structure, but recent theories suggest the existence of planar tetracoordinate carbon (ptC) structures that break traditional rules.
  • Researchers investigated a carbon cluster supported by phosphorus (C(P)) to identify a stable ptC configuration.
  • Their calculations found a five-atom ptC that is kinetically stable and may be detectable in experiments, with stability resulting from delocalized p-electrons and strong electrostatic interactions with the phosphorus framework.

Natural selection has driven the convergence toward a selected set of osmolytes, endowing them with the necessary efficiency to manage stress arising from salt diversity. This study combines atomistic simulations and experiments to investigate how two osmolytes, glycine and betaine, individually modulate the Hofmeister ion ordering of alkali metal salts (LiCl, KCl, and CsCl) near a charged silica interface. Both osmolytes are found to prevent salt-induced aggregation of the charged entities, yet their mode and degree of relative modulation depend on their intricate interplay with specific salt cations.

Article Synopsis
  • ALS is a serious disease that weakens muscles as people age, and it has different effects on different people.
  • Researchers found that a protein called FGF21 is significantly increased in the muscles of people with ALS, and it seems to help protect nerve cells when there’s stress on them.
  • High levels of FGF21 might mean the disease progresses more slowly and can help people live longer and healthier.

Hypothesis: Harnessing electrical energy from salinity gradients, particularly for powering micro and nanoscale devices, has become a focal point of recent research attention, due to its renewable and biocompatible nature. Much of the reported research in that direction revolves around optimizing the membrane architecture and the charge distribution to maximize the induced electric potential, with no particular emphasis on the fluid rheology. However, many of the modern miniature systems, typically the bio-inspired ones, concern fluids with complex rheological characteristics, where the results for Newtonian solvents may not trivially apply.
